Home Renovation Permits: When You Need Them and How to Get Them
A homeowner's guide to building permits — which projects require them, how the process works, and what happens if you skip them.
Permits exist to ensure work meets safety codes. They protect you, future buyers, and your neighbors. While the process can feel bureaucratic, unpermitted work creates serious problems at resale, with insurance claims, and if a city inspector discovers it. Here's what every homeowner should know.
Projects That Typically Require Permits
- Structural changes — removing or adding walls, changing rooflines
- Electrical work — panel upgrades, new circuits, EV charger installation
- Plumbing — moving drains, adding fixtures, water heater replacement
- HVAC — new furnace, ductwork modifications, mini-split installation
- Additions and conversions — finishing a basement, building a deck over a certain height
- Window and door replacements that change opening sizes
Projects That Usually Don't Need Permits
Cosmetic work that doesn't affect structure, electrical, or plumbing systems is typically permit-free — but always confirm with your local building department, as rules vary by municipality.
- Interior painting and wallpaper
- Replacing fixtures in the same location (faucet, toilet, light fixture)
- Installing new flooring over existing subfloor
- Cabinet refacing or replacement without plumbing changes
- Landscaping that doesn't involve drainage or retaining walls
The Permit Process Step by Step
- Contact your local building department — many have online guides
- Submit plans or scope documentation (your contractor usually handles this)
- Pay permit fees — typically $50–$500+ depending on project scope
- Schedule inspections at required milestones (rough-in, final)
- Receive certificate of occupancy or final approval
Who Pulls the Permit — You or Your Contractor?
The permit should be in the contractor's name, not yours. When a contractor asks you to pull the permit, they're often avoiding accountability — if work fails inspection, the permit holder is responsible. A reputable licensed contractor pulls their own permits as standard practice.
Risks of Unpermitted Work
- Required tear-out and redo if discovered during a sale inspection
- Insurance may deny claims related to unpermitted work
- Fines from the municipality
- Difficulty refinancing or selling — title companies flag unpermitted additions
- Safety hazards from work that never passed inspection
Frequently Asked Questions
How much do renovation permits cost?
Permit costs vary widely by location and project scope. A simple electrical permit might cost $50–$100. A full kitchen remodel permit could run $200–$800. Major additions are often calculated as a percentage of project value. Your contractor should itemize permit costs in their bid.
How long does it take to get a permit?
Simple permits may be issued same-day or within a week. Complex projects requiring plan review can take 2–8 weeks. Factor permit lead time into your project timeline — starting demo before permits are approved is illegal in most jurisdictions.
Can I get a permit after work is already done?
Some municipalities allow retroactive permits, but expect higher fees, mandatory inspections of concealed work (which may require opening walls), and potential fines. It's far easier and cheaper to permit before you start.
