Building Permit Process: A Step-by-Step Guide for Homeowners

May 18, 2026

Why Permits Exist

Building permits are not bureaucratic obstacles — they're the mechanism by which trained inspectors verify that work was done safely. Electrical fires, structural failures, and plumbing failures that cause water damage are often the result of unpermitted work that was never inspected. Permits protect you, future buyers, and your neighbors.

What Typically Requires a Permit

Always Requires a Permit

• Any structural change — removing load-bearing walls, adding beams
• Home additions and ADUs
• Electrical panel upgrades, new circuits, subpanels
• New plumbing runs, relocating plumbing
• HVAC system replacement or ductwork extension
• Deck additions or expansions
• Basement conversions to livable space
• Fence over certain height limits (varies by city)
• Pool installation

Usually Does Not Require a Permit

• Painting and wallpaper
• Replacing flooring (same material type, same footprint)
• Cabinet replacement without moving plumbing
• Countertop replacement
• Like-for-like fixture replacement (faucet, toilet, light fixture)
• Minor landscaping

When in doubt, call your local building department. They will tell you definitively whether a permit is required — and it's a free phone call.

Step-by-Step Permit Process

Step 1: Determine What's Required

Contact your city or county building department (or check their website) to confirm which permits apply to your project. Bring your project description and scope of work.

Step 2: Prepare Your Application

For simple projects, a site plan and description may suffice. For structural work, additions, or complex mechanical projects, you'll need architectural drawings and possibly structural engineering documents stamped by a licensed professional.

Step 3: Submit and Pay Fees

Permit fees are typically calculated as a percentage of project value — often 0.5–2% of the construction cost. A $50,000 remodel might incur $500–$1,000 in permit fees. Many jurisdictions now accept online applications.

Step 4: Await Approval

The building department reviews your plans for compliance with local codes. They may issue comments requiring revisions before approval. Build permit review time into your project timeline — 2–8 weeks is standard, up to 12 weeks in busy cities.

Step 5: Post Permit and Begin Work

Once approved, post the permit where inspectors can see it (usually on a front window). Work may not begin before permit issuance.

Step 6: Schedule Inspections

Different phases of work require different inspections:

• Rough framing inspection — before walls close
• Rough electrical inspection — before drywall
• Rough plumbing inspection — before walls close
• Insulation inspection — before drywall
• Final inspection — when work is complete

A licensed contractor schedules inspections as part of their job. If you're hiring for a project requiring permits, confirm that permit-pulling is included in your contract.

Step 7: Receive Certificate of Occupancy or Final Sign-Off

After the final inspection passes, you receive a signed permit card or certificate of occupancy. Keep this document — you may need it when you sell the home. Find a licensed contractor in your city who routinely manages the permit process.
