How to Get a Building Permit (Step by Step)
The typical homeowner permit process: documents, review, inspections, timelines and costs — plus where to start.
The exact paperwork differs by jurisdiction, but the homeowner permit process almost always follows the same arc. Use the permit checker to confirm your project needs one, then start at your county or city portal.
1. Determine if you need a permit
Call or check your local building department. Structural changes, electrical/plumbing/HVAC, decks, roofs, fences over height, and ADUs almost always require one; painting, flooring, and cabinets usually don't.
2. Prepare the documents
Completed application, project/site plans, contractor license + insurance, proof of ownership, and energy or HOA documents if required. Complex work may need engineered plans.
3. Submit and pay
Most large cities offer online permitting; smaller ones still use paper. Fees are usually based on project valuation (commonly ~$5–$15 per $1,000 of value), with plan-review fees often extra.
4. Plan review
Simple projects can be same-day to ~5 business days; standard residential work 5–20 business days; complex or new construction 4–8+ weeks. Incomplete applications are the top cause of delay.
5. Receive the permit and post it
Keep the approved plans on site and post the permit where inspectors can see it.
6. Schedule inspections
Foundation/footing, framing & rough-in (electrical/plumbing/mechanical), insulation, and final. Don't cover work before it passes.
7. Final approval
The final inspection closes the permit. Keep the record with your property permanently.
