Garden Pagoda or Pergola – What is the Difference?
“Pagoda vs pergola” comes down to roof vs shade. A pagoda is a solid-roof, tiered structure inspired by East Asian architecture. A pergola is an open-rafter structure built for filtered light and airflow. The real decision is whether you want true weather coverage—or open-air shade.
What You Will Learn
- The simplest way to tell a pergola from a pagoda (and what most people actually mean when they use those words)
- Which structure gives you real rain cover vs. filtered shade
- How roof style changes permitting, price, and long-term durability
- The “terminology trap” that causes homeowners to buy the wrong structure
- Real-world examples so you can choose confidently
You Searched “Pagoda vs. Pergola.” Here’s the Better Question to Ask First.
If you’re Googling pagoda vs pergola, the short answer is this:
pagoda is usually a style direction; pergola is usually a shade structure.
The internet usually gives you two definitions and a stock photo.
That’s not what you need.
What you’re really asking is: What should I build—and what do these options actually do?
That’s a much more useful question. And the honest answer is more complicated — and more important.
That’s why the pagoda vs pergola comparison only helps when we translate the words into real-world decisions: shade, roofline, budget, and how you’ll actually use the space.
It’s the hidden reason the pagoda vs pergola search gets so frustrating—because the labels shift, but the structural requirements don’t.
The outdoor structure world has a terminology problem that can cost homeowners real money. “Pagoda,” “pergola,” “pavilion,” “gazebo,” “arbor,” and “patio cover” get used interchangeably across Pinterest, contractor quotes, and big-box listings — even though they can mean very different structures with different engineering, shade performance, permitting, and price.
We’ve seen it firsthand across 4,000+ projects over 16 years. Someone asks for a “pagoda” and describes an open-rafter pergola. Someone asks for a “pergola” but is picturing a solid-roof pavilion. Someone wants a “gazebo” and sends a photo of a rectangular pergola with knee braces.
No one is wrong — the terminology is just inconsistent. So let’s make it simple: what these structures actually are, what matters for your space, and a framework you can use to evaluate any builder — not just us..
Pagoda vs. Pergola vs. Pavilion: The Real Structural Differences
Before we get into which one is right for your yard, you need to understand what’s actually different about these structures — not just aesthetically, but structurally. Because the differences affect your shade, your budget, your building permit, and how your structure performs in ten years.
What Is a Pergola?
A pergola is an outdoor structure with vertical posts supporting an open-roof system of beams and rafters. The key word is open. A pergola’s roof allows light and air to filter through while providing partial shade. Pergolas can be freestanding or attached to the home.
The word comes from the Late Latin pergula, meaning “projecting eave.” In modern American use, “pergola” has become the umbrella term homeowners apply to almost any outdoor overhead structure — which is exactly where the confusion starts (Source: WTF Complete Glossary).
What a pergola gives you:
- Partial shade with natural light and airflow
- Open, airy feel — you’re outside, not in a room
- Simpler engineering and permitting in most jurisdictions (open roofs don’t catch wind or shed water like solid roofs)
- Lower material cost than solid-roof structures at the same footprint
- A design canvas — shade planks, lattice density, and rafter spacing let you control exactly how much sun filters through
What a pergola does NOT give you:
- Full rain protection (water comes through the open roof)
- Complete sun blockage (though this depends entirely on the design — more on this below)
- The enclosed, room-like feel of a solid-roof structure
What is a pagoda?
A pagoda is a tiered tower structure with multiple upward-curving roof eaves, rooted in the architectural traditions of South and East Asia — primarily China, Japan, Korea, India, Nepal, and Vietnam.
Historically, pagodas were built for sacred purposes. In Japanese tradition, the five-tiered pagoda represents five elements: earth, water, fire, wind, and void (sometimes translated as air or spirit). The number of tiers, the curvature of the eaves, and the proportions all carried symbolic meaning. The Hōryū-ji temple complex in Nara, Japan — built in the early 7th century — contains one of the oldest surviving wooden pagodas in the world, and it’s still standing after nearly 1,400 years. That’s not a style trend. That’s a structural testament.
Here’s the distinction: a true pagoda is a solid-roof structure. Each tier is a fully enclosed roof layer. That makes a pagoda functionally closer to a pavilion — a freestanding structure with a solid, enclosed roof and open sides — than to a pergola.
This matters because:
- Solid roofs catch wind loads differently than open rafters (engineering changes significantly)
- Many building departments classify solid-roof structures differently for setback requirements and permitting
- Solid roofs require roofing materials, flashing, and drainage systems that open pergolas do not
- The cost profile changes — more material, more labor, more engineering complexity
When most American homeowners say “I want a garden pagoda,” they’re usually picturing one of three things:
- A true pagoda-style pavilion — solid tiered roof, curved eaves, Asian-inspired design. These are beautiful but complex to engineer, expensive to build correctly, and relatively rare in residential applications.
- A gazebo — a polygonal (usually hexagonal or octagonal) freestanding structure with a solid roof and open sides. The multi-sided shape is the defining feature that separates a gazebo from a rectangular pavilion.
- A pergola with Asian-inspired design elements — an open-rafter structure that borrows the tiered aesthetic, curved profiles, or proportional language of pagoda architecture without the solid roof. This is what most homeowners searching “garden pagoda” actually end up building.
What Is a Pavilion?
Since pagodas and pavilions share the solid-roof characteristic, it’s worth clarifying the distinction.
A pavilion is a freestanding structure with a solid, fully enclosed roof and open sides. It provides complete protection from sun, rain, and snow. Pavilions are typically rectangular, which distinguishes them from gazebos (polygonal) and pagodas (tiered).
The difference between a pavilion and a pagoda is primarily the roof profile. A pavilion has a single-plane roof (gabled, hipped, or flat). A pagoda has multiple tiered roofs with upward-curving eaves. Both provide full weather protection. Both require more engineering than an open

The Terminology Problem That Costs Homeowners Money
This isn’t just an academic vocabulary exercise. The terminology confusion has real financial consequences.
Scenario 1: You search “garden pagoda kit” and buy a $2,000 product online. It arrives in a flat box. The “pagoda” is a lightweight decorative garden ornament — thin metal, 6 feet tall, meant to look pretty next to a koi pond. It provides no usable shade, supports no furniture zone, and blows over in a 40 mph wind. You wanted a structure. You bought a decoration.
Scenario 2: You tell a contractor you want a “pergola” over your patio. The contractor builds an open-rafter structure. You’re disappointed because you wanted rain protection for outdoor dining. You were actually picturing a pavilion. Now you’re looking at a retrofit — adding a solid roof to an open structure that wasn’t engineered for the additional wind load, water drainage, or snow accumulation. That retrofit often costs more than building the right structure from the start.
Scenario 3: You search “pagoda-style pergola” and get quotes from three companies. Each company interprets “pagoda-style” differently. One quotes a solid-roof pavilion with curved eaves. One quotes a standard pergola with decorative rafter tails. One quotes a gazebo kit. The quotes range from $3,000 to $35,000. You can’t compare them because they’re not quoting the same thing.
The fix is knowing exactly what you mean before you call anyone. And now you do.
What Most People Actually Want (And Why a Pergola Usually Wins)
Here’s what we’ve learned: the vast majority of homeowners — including those who initially search for “pagoda” — end up choosing a pergola. Not because pergolas are better in every situation, but because what most people want from their outdoor space is best served by what a pergola does well.
Here’s why.
You Probably Want Shade, Not a Roof
This is the single most important distinction in the entire pagoda-vs.-pergola conversation.
A solid roof (pagoda, pavilion, or gazebo) gives you 100% shade. Always. Regardless of sun angle, time of day, or season. That sounds ideal — until you realize it also means zero natural light filtering through, and a darker, more enclosed feel that many homeowners don’t actually want.
A pergola gives you controllable shade. The amount of shade depends on the size of the rafters, the density of the shade planks, and the orientation relative to the sun.
Here’s where the physics starts.
We measure shade performance using ShadePrint™ — a proprietary metric that calculates actual shade coverage as a percentage of the structure’s footprint at peak sun angles. A standard Western Timber Frame pergola delivers 80%+ shade coverage through the combination of heavy timber rafters (3″ × 10″ on our 8,000 Series) and dense shade plank spacing.
For comparison, most mass-produced pergolas — especially lightweight aluminum or thin-timber kits — deliver 40–50% shade coverage. Same word. Same “pergola.” Half the shade.
The difference is timber size. A 2×2 rafter casts a 2-inch shadow. A 3×10 rafter casts a 10-inch shadow. Multiply that across 15–20 rafters plus shade planks, and the coverage gap becomes dramatic. This is physics, not marketing.
The honest trade-off: If you need 100% rain protection — if you’re putting a TV, electronics, or fine furniture under the structure that can’t get wet — a pergola isn’t the right choice. You need a pavilion or a louvered roof system. A pergola with 80% shade coverage still lets 20% of rain through.
But if what you want is a shaded outdoor space that still feels like outside — with dappled light, natural airflow, and the feeling of being in a garden rather than in a room — a pergola with proper timber dimensions and shade engineering outperforms a solid-roof structure on livability for most use cases.
The Wind and Weather Factor Nobody Mentions
Solid-roof structures catch wind. Open-rafter structures let it pass through.
This isn’t a minor engineering detail. It fundamentally changes the structural requirements, the foundation requirements, and the cost.
A solid-roof pagoda or pavilion acts as a sail in high winds. The engineering must account for uplift forces, lateral loads, and the potential for the roof to become a lever that rips the entire structure from its foundation. This is why solid-roof structures require heavier posts, deeper footings, and more robust connections — and why they cost more.
A pergola with open rafters lets wind flow through the structure. It still needs proper engineering — our structures are rated for 160+ mph winds thanks to the EarthAnchor™ Structural Knife Plate system — but the wind loads on an open-rafter structure are fundamentally lower than on a solid roof of the same footprint.
What this means for your project: If you live in a high-wind area, a hurricane zone, or a location with severe seasonal storms, a solid-roof pagoda or pavilion requires significantly more engineering investment to achieve the same wind rating as an open pergola. That cost is invisible in most quotes — you won’t see “wind engineering surcharge” as a line item — but it’s built into the price.
Permitting Is Often Simpler for Open-Roof Structures
Rules differ from city to city, so always confirm with your local building department. Still, it’s one of the most helpful things to understand early when comparing pagoda vs pergola — because it can shape your options before you ever choose a style.
Pergolas Cost Less at Every Size Tier
Because pergolas use less material (no roofing, flashing, or drainage) and require less complex engineering than solid-roof structures, they cost less at every comparable size.
Here’s what custom heavy timber pergolas actually cost, by size tier:
|

(Source: WTF Complete Pricing Guide. These are heavy timber prices — Grade A Douglas Fir, CNC-cut, shop-stained with Sherwin-Williams UV-rated finish, stamped engineering drawings included. Lightweight aluminum or thin-wood “pergola kits” from big-box stores start at $1,500–$5,000 but are a fundamentally different product.)
A comparable solid-roof pavilion at the same footprint will typically cost 30–50% more due to roofing materials, additional structural engineering, and drainage systems. A true pagoda-style structure with tiered, curved eaves adds compound-angle joinery complexity that increases fabrication cost further.
The Pagoda-Style Pergola: Why It Might Be Exactly What You’re Looking For
Here’s where this becomes useful — because now we’re moving from terminology to what you’ll actually experience in your yard.
You don’t have to choose between a pagoda and a pergola. You can build a pagoda-inspired pergola that borrows the aesthetic language of Asian architecture — tiered roof profiles, upturned rafter tails, layered visual depth — while keeping the structural and practical advantages of an open-rafter timber frame.
This is something we’ve built. We’ve designed tiered open-roof pergolas that borrow the pagoda’s upturned roof profile, creating a multi-level rafter system where each tier steps up and out, echoing the stacked eaves of traditional Asian temple architecture. The result is a structure that reads as “pagoda” from across the yard but performs as a pergola — open airflow, controllable shade, simpler permitting, and lower cost than a solid-roof equivalent.
What makes this work is the joinery.
Traditional pagoda architecture relies on interlocking wood joints — no nails, no metal fasteners. The joints lock tighter under load, which is why structures like the Hōryū-ji have survived nearly 1,400 years of earthquakes, typhoons, and weathering.
Our Dovetail Difference™ joinery system operates on the same principle. Precision-cut interlocking timber joints that fit wood-to-wood — no visible bolts, brackets, or metal hardware from the exterior. The joints get tighter under gravity rather than loosening over time. It’s the same physics that kept Japanese pagodas standing for centuries, applied with CNC precision cutting and modern structural engineering.
That’s not a coincidence. It’s geometry.
The aesthetic options for a pagoda-inspired pergola include:
- Tiered rafter profiles — multiple horizontal layers that create the stepped-roof silhouette
- Curved rafter tails — the upturned eave profile cut into decorative rafter tail ends
- Deeper knee braces — angled supports that echo the diagonal struts visible in pagoda architecture
- Layered shade planks — varying widths and spacings across tiers to create visual depth and shadow patterns that shift with the sun
- Color choices — from traditional muted tones (our Rich Cordoba or Natural finishes) to bolder statements (Black for dramatic contrast, or custom color matching for homeowners who want the vibrant palette associated with East Asian architecture)
All eight standard stain colors — Rich Cordoba, Canyon Grey, Early American, Rich Sequoia, Wild Olive, Black, Natural, and Alpine White — are shop-applied Sherwin-Williams UV-rated exterior stain, 2 backrolled coats, applied before shipping. Touch-up stain is included with every kit. Custom color matching is also available for homeowners who want a specific hue.
Garden Structures: Matching the Right Structure to Your Landscape
Both pagodas and pergolas have deep roots in garden design. If your primary goal is creating a garden focal point — Zen garden, xeriscape, botanical collection, or simply a beautiful anchor for your landscape — here’s how to think about which structure serves which purpose.
The Zen Garden or Japanese-Inspired Landscape
Zen gardens (karesansui, or “dry landscape” gardens) use carefully placed rocks, raked gravel, and minimal plantings to evoke natural landscapes in miniature. Islands, mountains, and flowing water are suggested through stone placement and gravel patterns.
A structure in a Zen garden needs to complement this restraint — not compete with it. This is where a smaller pergola (Lounge size, 10×10 to 12×12) in a natural or muted stain often works better than a visually complex pagoda. The heavy timber posts frame the garden view without overwhelming it. The open rafters allow the sky to remain part of the composition.
For homeowners who want the pagoda reference, a simple tiered rafter profile with curved tails on a Lounge-size pergola achieves the Asian-inspired aesthetic while keeping the structure proportional to the garden. Think of it as a haiku, not an epic — restrained, intentional, and more powerful for what it leaves out.
The Botanical or Collector’s Garden
For gardens built around plant collections, shade control is the design driver. Different plants need different light levels, and an open-rafter pergola lets you tune the shade by adjusting plank spacing — dense coverage for shade-loving species, wider spacing for sun-tolerant plants.
Heavy timber pergolas also provide excellent support for climbing plants — wisteria, climbing roses, jasmine, grapevines. The 8×8 posts of our 8,000 Series can support significant vine weight without the structural compromise that lightweight structures experience when mature vines add hundreds of pounds of dead load over time.
A physics note on climbing plants and pergolas: Mature wisteria can add 40–60 pounds of weight per linear foot of beam. A lightweight aluminum pergola with 2×2 posts was not engineered for that load. A heavy timber pergola with 8×8 posts and 4×12 beams was. If you’re planning a vine-covered garden pergola, the structural capacity of the frame isn’t just about wind and snow — it’s about the living weight that accumulates over years.
The Poolside or Patio Garden
Pools and gardens share a common need: shade that doesn’t feel like a ceiling. A pergola beside a pool creates a shaded retreat while keeping the open-sky feel that makes poolside areas inviting. A solid-roof pagoda or pavilion next to a pool can feel like a wall between the pool area and the sky.
This is also where material choice matters most. Pool environments mean water exposure, chemical splash, reflected UV, and people touching the structure in swimwear.
Heavy timber has a critical advantage here: thermal mass. Wood absorbs heat slowly and releases it slowly. On a 100°F day, a heavy timber post is touchable — warm to the hand but not painful, typically staying below 115°F even in direct sun. An aluminum or steel structure in the same sun can exceed 150°F — hot enough to burn skin on contact.
If you have children running between the pool and the pergola, grabbing posts, leaning against beams, this isn’t an aesthetic preference. It’s a safety consideration.

Regardless of which structure type you choose, the quality questions are the same. Here’s a framework you can use to evaluate any outdoor structure company.
8 Questions to Ask Any Outdoor Structure Company
|
#Question |
Why It Matters |
What a Strong Answer Sounds Like |
|---|---|---|
|
What is the shade coverage percentage? |
“Pergola” means nothing without a shade metric. 40% shade and 80% shade are different experiences. |
A specific number or range, measured by a defined methodology. Vague answers (“plenty of shade”) are a red flag. |
|
What are the actual timber dimensions? |
Post size, beam depth, and rafter width determine visual presence, structural capacity, shade, AND cost. |
Specific dimensions (e.g., “8×8 posts, 4×12 beams”). If they can’t tell you, they may not know. |
|
What species and grade is the wood? |
Grade determines knot density, grain consistency, and long-term performance. Species determines rot resistance, stain behavior, and aging. |
Grade A Douglas Fir, Coast Redwood, or Western Red Cedar — with the grade specified. “Premium wood” is not an answer. |
|
Is the hardware custom-engineered or off-the-shelf? |
Off-the-shelf hardware from a big-box store is not equivalent to hardware specced for a specific structure’s loads. |
Custom-engineered for each project. If it comes from a catalog, it’s generic. |
|
What protects the post base from moisture? |
Ground contact is the #1 rot point. Without a moisture barrier, the posts begin deteriorating from day one. |
A concealed structural system (like an EarthAnchor™ Structural Knife Plate) that creates a moisture barrier AND structural anchor. |
|
What protects the top joint from water? |
The post-to-beam connection is the #1 overlooked moisture-pooling point in outdoor structures. |
A dedicated cap or seal system. If they don’t have an answer, they haven’t thought about it. |
|
Does the quote include stamped engineering drawings? |
Stamped engineering means a licensed professional has certified the structure meets code for your specific location — snow loads, wind loads, seismic. |
“Yes, included with every project.” If it’s an add-on or not available, the structure may not be engineered for your site. |
|
Can I run electrical without exposed conduit? |
If you want lights, fans, heaters, or outlets, how you get power to the structure matters for aesthetics and long-term function. |
Integrated wiring inside the posts (like TimberVolt® Power Posts). If the answer is “hire an electrician after,” you’ll have visible conduit forever. |
Use this for any company, any structure type. A good company will welcome these questions. A company that deflects or can’t answer them is telling you something important about what they’re actually building.
Honest Limitations: When a Pergola Isn’t the Right Answer
We design and build timber structures of all kinds. And our goal isn’t to steer you into a pergola by default — it’s to help you choose the structure that actually serves your space.
Choose a pavilion or solid-roof structure instead of a pergola if:
- You need 100% rain protection — outdoor TV setups, fine furniture, electronics, or commercial dining where weather closures cost revenue
- Your climate has extended rainy seasons and the structure is your primary outdoor living space
- You want a fully enclosed feel — some homeowners prefer the “room” experience over the “garden” experience, and that’s a legitimate preference
Choose a decorative garden pagoda (not a structural pergola) if:
- You want a small ornamental accent for a garden, not a functional shade structure
- Your budget is under $3,000 and you’re looking for a visual focal point rather than usable outdoor living space
- The structure won’t be used for seating, dining, or gatherings
A custom heavy timber pergola may not be right for you if:
- You’re renting your home or planning to move within 1–2 years (though pergolas do add resale value — see our ROI guide)
- Your total outdoor structure budget is under $8,000 (our Lounge tier starts there — below that, you’re looking at lightweight kits, which serve a different purpose)
- You need the structure installed within a week (custom engineering, CNC fabrication, and shop-applied stain take time — we’re building furniture-grade outdoor architecture, not assembling a kit)
We’d rather tell you that upfront than discover it after you’ve invested time in the design process. That honesty is part of how we operate.

How Climate Should Influence Your Pagoda vs. Pergola Decision
Your climate doesn’t just affect which structure looks right. It affects which one lasts.
Hot, Arid Climates (Desert Southwest, Southern Utah, Arizona)
Shade is the primary need, not rain protection. A pergola with 80%+ ShadePrint™ coverage handles this efficiently. Solid-roof structures can trap heat underneath, creating an oven effect — the opposite of comfort. Open rafters allow hot air to rise and escape.
Stain maintenance is more frequent on south-facing structures in desert climates. UV degradation is primarily cosmetic, but pigmented stains (Rich Cordoba, Canyon Grey, Black) slow the process significantly compared to the Natural clear finish.
Cold, Snowy Climates (Wasatch Front, Park City, Mountain West)
Snow load is the engineering driver. Pergola rafters shed snow as it accumulates (it falls through the open gaps). Solid-roof structures must be engineered to hold the full snow load — which in mountain jurisdictions can be 60+ pounds per square foot. That’s serious structural weight that requires heavier beams, deeper footings, and more robust connections.
This is why stamped engineering drawings matter. A pergola “rated for 30 psf snow load” on a generic spec sheet means nothing if your jurisdiction requires 60 psf. Every Western Timber Frame project includes stamped structural engineering specific to your location.
Coastal Environments
Salt air accelerates finish degradation, corrodes standard hardware, and attacks metal structures aggressively. A custom timber pergola for a coastal location should include stainless steel hardware (not standard galvanized), marine-grade sealants, and shorter stain maintenance cycles. See maintenance tips.
We factor coastal specifications into the quote when the customer identifies a coastal location — stainless fasteners and upgraded treatment are included, not sold as a surprise add-on.
High-Wind Regions
As discussed above, open-rafter pergolas handle wind better than solid-roof structures. But “handles wind better” doesn’t mean “doesn’t need engineering.” The EarthAnchor™ Structural Knife Plate system — concealed aluminum plates within the post that serve as both moisture barrier and structural anchor — contributes to our 120+ mph wind rating. That’s hurricane-rated. It’s also completely invisible. No one sees the engineering from the outside. They just see timber.
A Brief History: Why These Structures Both Exist
Understanding the history isn’t just interesting — it explains why the design principles work.
Pagodas evolved from Indian stupas (Buddhist reliquary mounds) that traveled along the Silk Road into China, Japan, Korea, and Southeast Asia beginning around the 1st century CE. As the form adapted to local architectural traditions, it developed the characteristic tiered, upward-curving roof profile. Japanese pagodas — particularly the five-story gojū-no-tō — are engineering marvels. The central shinbashira (heart pillar) acts as a massive pendulum that counterbalances seismic forces, which is why these wooden towers have survived 1,400 years of Japanese earthquakes. The interlocking wood joinery distributes load through friction and geometry rather than fasteners — a principle that still outperforms bolt-dependent connections in long-term durability.
Pergolas trace to ancient Egypt and Rome, where they covered walkways in gardens and vineyards. The Roman pergula supported grapevines over outdoor passages — functional shade that also produced wine. The form spread through Italian Renaissance gardens, where pergolas became central to the idea of designed outdoor space as an extension of architecture. In modern American residential design, the pergola has become the most popular outdoor structure type because it bridges the gap between “inside” and “outside” better than any solid-roof alternative.
Both traditions arrived at the same conclusion: heavy timber, interlocking joinery, and respect for the physics of load, weather, and time. The styles look different. The engineering principles are remarkably similar.

In the end, “pagoda vs. pergola” is a bit like arguing over whether you want a “sports car” or a “coupe.” The words are real, but they’re not what you actually live with. What you live with is shade (or not), rain protection (or not), whether the structure feels like a garden accent or a proper outdoor room, and whether it behaves politely in wind, snow, and real life. So yes—learn the definitions. Then ignore them and choose based on outcomes. The right question isn’t “What is it called?” It’s “Will this make an ordinary Tuesday outside better?”
Frequently Asked Questions
What is the difference between a pagoda vs pergola?
A pagoda is traditionally a tiered, solid-roof structure inspired by East Asian architecture and designed for shelter. A pergola is an open-rafter structure that provides filtered shade and airflow rather than full rain protection. The key difference is roof coverage versus open shade.
Does a pergola protect from rain?
A traditional pergola does not provide full rain protection because it has open rafters. It creates filtered shade and partial coverage. If full rain protection is desired, a solid-roof pavilion or covered structure is typically a better option.
Is a pagoda the same as a pavilion?
Not exactly. A pagoda refers to a specific architectural style with tiered rooflines and East Asian origins. A pavilion is a broader term for a freestanding structure with a solid roof supported by posts. Some pavilion designs can incorporate pagoda-style roof elements.
Which is better for a backyard, a pagoda or a pergola?
The better choice depends on how you want to use the space. If you want filtered sunlight and airflow, a pergola is often ideal. If you want full overhead protection from rain and stronger shade coverage, a solid-roof pavilion or pagoda-style structure may be more appropriate.
Do pagodas require permits?
Permit requirements depend on local building codes, structure size, and whether the structure has a solid roof. Solid-roof structures such as pavilions or pagoda-style roofs are more likely to require permits than open pergolas.
