Planning a room addition, second story or garage-to-living conversion and not sure what your building department expects to see? Download our free sample home addition and garage conversion permit drawing below. It is a real set we prepared for a past project, with client details removed, so you can see how the sheets are organized and what plan reviewers usually ask for.
What's in the free sample
The PDF has four sheets taken from a real permit set we drew for a past client:
- Room addition floor plan and wall section
- Room addition elevations
- Garage conversion floor plan
- Garage conversion elevations
Client names, addresses and parcel details have been removed, and every sheet is marked "Free sample – not for construction". The structural calculations, general notes and the remaining sheets are not included. This file is for reference only: it shows the level of detail a plan reviewer expects, but it cannot be submitted for a permit.

How to use this sample
- Compare it with your city or county permit checklist.
- Use it to sketch your own project and gather the information you need.
- Share it with your contractor so everyone agrees on the scope.
Important: this sample is for reference only. It is not stamped, and it was drawn for a different address, code and loads. Do not submit it for your permit.
Tips before you start
- Measure the existing rooms that connect to the addition.
- Photograph the attic and crawlspace so framing directions are clear.
- For garage conversions, check parking replacement rules in your city.
When you need custom drawings
Most cities need drawings made for your exact address, size and local code, and some also require a professional engineer's stamp. We prepare permit drawings for projects in all 50 states and send a fixed quote within 24 hours. If your city requires a stamp, it comes from an independent licensed PE under a separate arrangement.
