Engineering & Permitting
Subject: The Engineering Behind Your Structure
Hi [First Name],
One of the questions we hear most often is about engineering and permits — what is included, what is required, and who handles what. The short answer: we handle the engineering. You handle the local permit. And we give you everything you need to make that process straightforward.
Here is how it works, and why it matters more than most people expect.
01
Every Kit Is Engineered
Every Western Timber Frame kit ships with a full set of stamped structural engineering plans. These plans are tailored to your structure’s design and adjusted for the load requirements of your specific location.
The engineering covers everything from post footings to ridge connections. It accounts for the roofing material you choose, the upgrades you select, and the environmental forces your structure will face over its lifetime.
This is included with every kit. You do not pay separately for engineering, and you do not need to hire your own structural engineer.
02
What the Engineering Covers
Designed for Your Site, Your Climate, Your Structure
Snow Load
Calculated for your specific location using local ground snow data. Roof pitch, span, and roofing material all factor into the design. Structures in heavy snow regions get heavier timber and reinforced connections.
Wind Load
Engineered to meet the wind exposure requirements for your site. Open terrain, coastal zones, and elevated locations each require different bracing and anchorage calculations.
Seismic
For locations in seismic zones, the engineering includes lateral force resistance and connection detailing that meets or exceeds local code requirements.
The engineering behind your structure is tailored to where it will stand, ensuring it is designed for the specific demands of your site rather than a one-size-fits-all standard.
03
Permitting
What to Expect and How We Help
Most municipalities require a building permit for an outdoor structure — especially one with a roof, electrical, or a permanent foundation. The permit process varies by location, but the core requirement is almost always the same: stamped structural engineering plans.
The engineering package we provide is designed to give your local building department what they need to approve the project. In most cases, our plans are accepted as submitted.
Occasionally, a local jurisdiction will request additional details or site-specific information. When that happens, we work directly with your building department to address their questions and provide whatever supplemental documentation they need.
We Handle
- Custom structural engineering for your kit
- Stamped plans ready for permit submission
- Load calculations (snow, wind, seismic)
- Responding to building department questions
- Supplemental documentation if requested
You Handle
- Submitting the permit application locally
- Paying any local permit fees
- Scheduling inspections with your building department
- Any site-specific requirements (property line setbacks, HOA approval)

How the Process Works
Most families are surprised by how smooth this process is. The engineering is already done. The plans are already stamped. The permit submission is usually a matter of dropping off or uploading the documents we provide.
05
What to Ask Your Building Department
Before you start the permit process, a quick call to your local building department can save time and set expectations. Here are the questions worth asking:
If your building department has questions about the engineering, let us know. We work with building departments across the country and are happy to speak with them directly.
You are not figuring this out alone. We have done this over 7,000 times. If you have questions about the engineering or permitting process for your specific location, we’re here to walk you through it. Every project is different, and I’d be happy to help you understand what to expect for yours.
Looking forward to helping you create a space you’ll love for years to come,
