Does a kitchen remodel require a permit?

A kitchen remodel that moves plumbing, adds new circuits, or changes gas lines requires a permit in most states. A cosmetic remodel — new cabinets, countertops, or appliances in the same location without moving plumbing or electrical — typically does not. When in doubt, ask your local building department before work begins. If a permit is required and your contractor skips it, the work may have to be demolished and redone.

Does a bathroom remodel require a permit?

Any bathroom remodel that moves plumbing — relocating a toilet, shower, or drain — requires a permit in most states. Replacing a toilet or faucet in the same location typically does not. Adding a bathroom where none existed always requires a permit. Full bathroom gut-renovations that expose framing or change electrical circuits also require permits in most jurisdictions.

What happens if my contractor does renovation work without a permit?

Unpermitted work creates three problems: your homeowner's insurance may deny claims related to the work, you must disclose unpermitted work when you sell (it can reduce your home's value or delay closing), and the work was never inspected for code compliance. To remedy unpermitted work, you typically need to open walls so an inspector can verify the work, which is expensive. Stop work immediately if you discover your contractor is skipping permits.

How do I check if my contractor pulled a permit for my project?

Search your local building department's online permit portal by your property address. Most county and city building departments have a free public permit search. Look for the permit type, issue date, contractor name, and permit status. If no permit appears within two weeks of the project start date, ask your contractor for the permit application number directly.

Do I Need a Permit for My Renovation? A State-by-State Guide

Whether your renovation needs a permit depends on three things: what you're doing, how much it costs, and where you live. The same deck addition that requires a permit in California might not require one in Montana. The bathroom remodel that sails through in Texas might trigger three separate inspections in New York City. Here's what you need to know before your contractor starts.

This guide covers which renovation types typically require permits, how states differ, and what happens when a contractor skips the permit process.

What types of home renovations require a permit in most states?

Structural changes, electrical work, plumbing modifications, HVAC installations, and additions almost always require a permit regardless of state. Cosmetic changes — painting, flooring, cabinet replacement, fixture swaps — almost never do. The gray area is in the middle: decks, fences, window replacements, and bathroom remodels vary significantly by jurisdiction.

The projects that reliably require permits in most states:

Any structural work (load-bearing walls, foundations, framing changes)
Electrical panel upgrades, new circuits, or service changes
Plumbing that moves or adds drain, waste, or vent lines
HVAC system installation or replacement (in most states)
Room additions, accessory dwelling units (ADUs), or garage conversions
Roofing replacement in most jurisdictions (not all)
Decks over a certain height (typically 30 inches) or over a certain square footage
Fences over a certain height (typically 6 feet)

The projects that often do not require a permit:

Interior painting and wallpaper
Flooring replacement (hardwood, tile, carpet) without subfloor changes
Kitchen cabinet replacements without moving plumbing or gas lines
Fixture replacements (faucets, light fixtures, toilets) in the same location
Insulation replacement without structural changes

How do permit requirements differ by state?

States don't set individual permit requirements — local building departments do, within a framework set by state building codes. This means permit requirements vary not just state to state, but city to city. However, states can be grouped into general permitting categories based on how closely they follow the International Residential Code (IRC) and how aggressively local jurisdictions enforce it.

Permitting Category	States	Characteristics	Typical Threshold
Strict	California, Florida, New York, New Jersey, Massachusetts, Maryland, Connecticut, Hawaii	Close IRC adoption, active enforcement, permits required for most renovations; inspections mandatory	Most structural, electrical, plumbing, HVAC, and exterior work
Moderate	Arizona, Colorado, Georgia, Illinois, Michigan, Minnesota, North Carolina, Oregon, Pennsylvania, Virginia, Washington, Wisconsin	IRC adopted with amendments; enforcement varies by city/county; major work almost always requires permit	Structural, electrical, plumbing; some exterior work; HVAC varies
Variable	Texas, Ohio, Indiana, Missouri, Kansas, Nebraska, South Dakota, Wyoming	No statewide building code in some; local enforcement varies widely; rural areas may have minimal requirements	Structural and electrical often required in cities; rural areas may require nothing
Lighter	Montana, Idaho (rural areas), Arkansas, Mississippi, Alabama (rural areas)	Lower enforcement density; rural areas often operate without active permit inspection	Primarily structural and health/safety work; cosmetic and moderate renovations often not required

What happens if your contractor skips the permit?

Unpermitted work creates three problems that outlast the renovation itself: insurance risk, resale risk, and code compliance risk. Your homeowner's insurance may deny claims for damage from unpermitted work. When you sell, buyers and their lenders will discover unpermitted work in a title search or home inspection — and they can require it to be permitted or demolished before closing.

Unpermitted work also means no inspections occurred. Inspections aren't bureaucratic obstacles — they catch real defects. Electrical defects are among the most common issues found in renovations done without permits, and missed wiring errors are a leading cause of residential fires.

If you discover mid-project that your contractor hasn't pulled a permit, stop work. Don't let additional work proceed on an unpermitted foundation. Ask the contractor to pull the permit immediately or hire a permit expediter if the contractor is unwilling. See our guide on how to check if your contractor pulled a permit for the steps to verify permit status yourself.

Can a homeowner pull their own permit?

In most states, homeowners can pull permits for work on their own primary residence — this is the owner-builder exemption. It allows you to act as your own contractor for permitting purposes. The risk is that the owner-builder exemption can complicate home sales: some states require disclosure of owner-pulled permits, and buyers may view them with skepticism.

The more practical issue is that if you pull the permit for work a contractor is performing, you become legally responsible for the work meeting code. If the contractor does defective work on your owner-pulled permit, your legal recourse against them is more complicated. Most real estate attorneys recommend letting the licensed contractor pull their own permit for exactly this reason.

How do you verify your contractor pulled the permit before work starts?

Search your local building department's online permit portal by your property address. Most counties and cities have a public permit search tool. Look for the permit type (it should match your project), the issue date, the contractor name, and the permit status (open, closed, approved). If no permit appears within two weeks of the contractor starting work, ask for the permit application number.

A contractor who resists showing you the permit number or delays pulling the permit has already told you something important about how they operate. Permit-pulling is a baseline professional behavior — not a burden. Before you hire, verify the contractor's license is active and check whether they have a history of permit violations or disciplinary complaints.
