The short answer
Yes — many houses are permitted from stock plans every year. But a stock plan is designed to sell nationally, not to satisfy your county. Expect to add local information, and don't be surprised by a correction letter on the first submittal.
Why stock plans get permit corrections
- No local loads — wind, snow and seismic design values vary by location.
- Generic foundation — frost depth, soil conditions and foundation type differ.
- No climate-zone energy data — insulation and window values are rarely included.
- Local amendments — counties modify the IRC; stock plans follow the base code, sometimes an older edition.
- No site plan — setbacks, drainage and utilities are always site-specific.
- Stamp requirements — some jurisdictions require an engineer's or architect's seal on residential plans or on structural sheets.
What usually needs to be added or adapted
| Item | Who |
|---|---|
| Site plan with setbacks, drainage, utilities | Drafter / surveyor |
| Foundation adapted to local frost depth and soil | Drafter or engineer |
| Energy notes for your climate zone | Drafter; compliance report per local rules |
| Local wind/snow/seismic design, braced walls | Drafter (prescriptive) or engineer |
| Smoke/CO, egress and stair details per local amendments | Drafter |
| Engineer or architect seal, where required | Licensed professional |
Call your building department before submitting and ask what they require for plans not drawn locally. It's the cheapest five minutes of the project.
Licenses and modifications
Stock plans are copyrighted. Check what your license allows before anyone edits the drawings: many plan sellers offer a reproducible or CAD license that permits modifications by a local professional. If you want layout changes as well, see our plan modification service.
Our stock house plan review flags what your county is likely to ask for — from $99.
See stock plan reviewGetting a stock plan permit-ready
- Buy the right license — CAD or reproducible if changes will be needed.
- Ask the building department about stamps, energy compliance and required sheets.
- Get a plan review to catch problems before submittal (stock house plan review).
- Add local information — site plan, foundation, energy, loads.
- Submit a complete set and respond fully to any corrections.

Already submitted and got corrections?
That's the most common path. Upload the correction letter and your stock plan set to our Permit Correction Service. You'll see instantly which comments are drafting fixes and which need an engineer. We fix every drafting comment and write the response letter — $499 flat — provided you own the plans or your license allows modifications.
Frequently asked questions
Can I get a building permit with a stock house plan?
Yes, many homes are permitted from stock plans. Most need local additions — site plan, foundation for local conditions, energy notes and sometimes an engineer’s seal.
Why was my stock house plan rejected by the building department?
Usually because it lacked local information: design loads, foundation for your frost depth and soils, energy code values for your climate zone, local amendments or a site plan.
Do stock house plans need an engineer stamp?
It depends on the jurisdiction and the design. Some require sealed structural sheets; many accept prescriptive IRC design for simple houses.
Can someone else modify my stock plan for the permit?
Yes, if your plan license allows modifications. Many sellers offer a CAD or reproducible license for this.
Can you fix permit corrections on a stock plan?
Yes — $499 flat for every drafting comment, provided you own the plans or your license allows modifications. Engineering items are listed separately.
