Do I need a permit for a bathroom remodel?

It depends on the scope. Cosmetic updates like new tile, paint, or replacing a vanity with no plumbing changes typically do not need a permit. But if you're moving plumbing fixtures, adding new electrical circuits, or changing the layout, you'll need a permit in virtually every jurisdiction. When in doubt, call your local building department — it's a free call.

What happens if I do work without a permit?

Consequences include fines ($500-$10,000+), forced removal or demolition of the unpermitted work, difficulty selling your home (buyers' inspectors and title companies flag unpermitted additions), insurance claim denials for damage related to unpermitted work, and personal liability if someone is injured due to code-noncompliant construction.

How much do building permits cost?

Permit fees vary by municipality and project value. Typical ranges: minor mechanical permits (electrical, plumbing) run $75-$500. Renovation permits run $500-$2,500. New construction or addition permits run $2,000-$10,000+. Most jurisdictions calculate fees as a percentage of the project's estimated construction value, usually 1-2%.

How long does it take to get a building permit?

Simple permits (water heater replacement, electrical panel upgrade) are often issued same-day or within a week. Renovation permits typically take 2-4 weeks for plan review. Addition or new construction permits can take 4-12 weeks, depending on the complexity and your local building department's backlog. Some cities offer expedited review for an additional fee.

Who is responsible for pulling permits — me or the contractor?

Your general contractor should pull all permits. This is important because when the contractor pulls the permit, they are legally responsible for the work meeting code. If you pull the permit as a homeowner, that responsibility shifts to you. Additionally, permits pulled by a licensed contractor often receive more thorough inspection oversight.

Permit Requirements by Project Type: What Needs a Permit in 2026

April 16, 2026

Building permits exist to protect you. They ensure that construction work meets safety codes for structural integrity, fire protection, electrical safety, and plumbing sanitation. But homeowners are often confused about which projects require permits and which don't. This guide covers the most common residential projects and their permit requirements in 2026.

Projects That Almost Always Require a Permit

Home Additions

Any addition of new square footage — whether it's a sunroom, bedroom, second story, or garage conversion — requires a building permit everywhere in the United States. This includes a home addition of any size. You'll typically need:

A building permit (structural, framing, finish)
An electrical permit
A plumbing permit (if the addition includes a bathroom or kitchen)
A mechanical permit (HVAC)
Possibly a zoning variance if the addition affects setbacks or lot coverage

Typical cost: $2,000–$10,000 in permit fees. Timeline: 4–12 weeks for plan review and approval.

Structural Changes

Removing or modifying a load-bearing wall, adding a beam, cutting a new window or door opening, or altering the roofline all require structural permits. These projects usually need stamped engineering drawings showing that the new configuration can support the loads.

Typical cost: $500–$3,000 for the permit, plus $1,500–$5,000 for engineering drawings. Timeline: 2–6 weeks.

Electrical Work

Adding new circuits, upgrading the electrical panel, running new wiring, or installing a subpanel all require an electrical permit. In most jurisdictions, even adding a single new outlet requires a permit if it involves running new wire from the panel.

Typical cost: $75–$500. Timeline: Same-day to 2 weeks.

Plumbing Work

Moving or adding plumbing fixtures (sinks, toilets, showers, water heaters), rerouting drain lines, or connecting to the sewer main requires a plumbing permit. Replacing a faucet or toilet with the same type in the same location usually does not.

Typical cost: $75–$500. Timeline: Same-day to 2 weeks.

HVAC Installation or Replacement

Installing a new furnace, air conditioning system, heat pump, or ductwork requires a mechanical permit. Replacing an existing unit with the same type and capacity may or may not require a permit — check your local code.

Typical cost: $100–$500. Timeline: Same-day to 2 weeks.

Roofing

Full roof replacement almost always requires a permit. Many jurisdictions now require permits even for re-roofing over existing shingles. The permit ensures the roofing materials and installation method meet wind and fire ratings for your area.

Typical cost: $150–$500. Timeline: Same-day to 1 week.

Decks and Porches

Any deck more than 30 inches above grade requires a building permit in most jurisdictions. Many cities require permits for all attached decks regardless of height. Freestanding decks under 200 square feet and under 30 inches are exempt in some (but not all) areas.

Typical cost: $200–$1,500. Timeline: 1–4 weeks.

Fences

Fence permits depend heavily on local ordinance. Many cities require permits for fences over 6 feet tall, fences in front yards, or fences within a certain distance of property lines. Some cities require permits for all fences. Check with your building department or HOA.

Typical cost: $50–$300. Timeline: Same-day to 2 weeks.

Projects That Usually Do NOT Require a Permit

These projects are generally exempt from permits in most U.S. jurisdictions, but local rules vary:

Painting: Interior and exterior paint, wallpaper
Flooring: Replacing carpet, hardwood, tile, or laminate (no subfloor structural changes)
Cabinets: Replacing kitchen or bathroom cabinets in the same footprint
Countertops: Replacing countertops without plumbing changes
Fixtures: Swapping light fixtures, faucets, or toilets with same-type replacements
Drywall repair: Patching holes, retexturing
Landscaping: Planting, grading (unless it affects drainage patterns)
Small sheds: Under 120 sq ft and not on a permanent foundation (varies by city)

Important caveat: "Usually exempt" is not "always exempt." Some cities require permits for work that other cities consider minor. When in doubt, spend 5 minutes calling your local building department. They'll tell you what you need.

The Permit Process Step by Step

Submit an application. Your contractor fills out the application and submits it with project plans, engineering drawings (if required), and the fee. Many cities now accept online submissions.
Plan review. The building department reviews your plans for code compliance. They may request revisions. This takes 1-12 weeks depending on the project and jurisdiction.
Permit issued. Once approved, the permit is posted visibly at the job site.
Inspections during construction. The building inspector visits at key milestones — foundation, framing, mechanical rough-in, insulation, and final. Each inspection must pass before the next phase begins.
Final inspection and certificate of occupancy. After all work is complete and passes final inspection, the building department closes the permit. For additions, you may receive an updated certificate of occupancy.

Permit Costs by Project Type (2026 Averages)

Bathroom remodel (with plumbing changes): $200–$1,000
Kitchen remodel (with electrical/plumbing): $500–$2,000
Home addition (400 sq ft): $2,000–$6,000
Whole-house renovation: $3,000–$10,000
New deck (300 sq ft): $200–$1,000
Electrical panel upgrade: $100–$400
New HVAC system: $150–$500
Roof replacement: $150–$500
Fence (6 ft privacy): $50–$300

What Happens Without a Permit

Skipping permits is never worth the risk. Consequences include:

Fines: $500–$10,000+ depending on the jurisdiction and severity
Forced removal: The city can require you to tear out unpermitted work, even if it was done correctly
Insurance denial: If unpermitted electrical work causes a fire, your insurer can deny the claim
Sale complications: Buyers' inspectors and title companies flag unpermitted additions, additions that don't match tax records, and work that doesn't meet code. This can kill a sale or require expensive corrections at closing.
Liability: If someone is injured due to code-noncompliant work, you bear personal liability

Your contractor should handle the entire permit process. If they suggest skipping permits to save money or time, that's a serious red flag. Find a contractor who does it right — browse licensed contractors in your city.
