Does a Contractor Need a Permit for That?

You’re getting bids on a basement finish, and one contractor says, “We’ll handle the permits — it’s included.” Another says, “You can save money if we skip the permit — the work’s the same.” The second offer feels tempting — it’s cheaper and faster, right?

Here’s the truth: work that requires a permit and doesn’t get one can cost you a lot more than the permit fee. We’re talking double permit fees, ripped-out walls, fines from the city, and headaches when you try to sell your house. Permits exist for a reason, and that reason is your safety.

This guide covers when a contractor needs a permit, what happens if they skip one, and how to protect yourself — without needing a law degree to figure it out.

When does work actually need a permit?

Building codes vary by state, county, and city — but the general rule is the same almost everywhere: if the work involves structural changes, electrical, plumbing, mechanical systems (HVAC), or certain types of exterior work, you need a permit.

Work that almost always requires a permit

New construction. Any new structure — a house, garage, shed over a certain size, deck, or addition — requires a building permit. The threshold for sheds and small structures varies by jurisdiction (anywhere from 100 to 200 square feet), so check with your local building department.

Structural changes. Moving or removing walls, cutting into ceiling joists or roof rafters, adding windows or doors where there weren’t any before, or changing the roofline. If you’re changing the structure of your home, a permit is required.

Electrical work. Adding new circuits, installing new outlets or switches, running wire for a new appliance, upgrading your electrical panel, or any work that involves the main service. Replacing an existing outlet or light fixture (same location, same wiring) usually doesn’t need a permit, but adding new ones does.

Plumbing work. Adding new plumbing lines, moving fixtures, installing a new water heater, or making changes to your main supply or drain lines. Replacing an existing faucet or toilet that connects to existing supply lines typically doesn’t need a permit.

HVAC work. Installing a new furnace, air conditioner, or ductwork. Replacing an existing unit with a like-for-like replacement usually requires a permit for the mechanical work, even if it’s a straightforward swap.

Major renovations. Gutting a kitchen or bathroom and moving plumbing or electrical lines — almost always needs permits. The threshold is usually whether you’re changing the layout or just replacing finishes.

Decks and porches. Most jurisdictions require permits for decks above a certain height (typically 30 inches above grade) or attached to the house. Freestanding ground-level decks may or may not need one.

Roofing. Some jurisdictions require permits for re-roofing, especially if you’re adding layers or changing the structure. Check with your local building department.

Water heater and furnace replacements. Even simple replacements often require permits because of gas line connections, venting requirements, and safety codes.

Work that usually doesn’t need a permit

Cosmetic updates. Painting, wallpapering, installing new flooring (if you’re not changing the subfloor), and replacing cabinet fronts — these are finish work, not structural changes.

Replacing fixtures (same location). Swapping out a faucet, changing a light fixture, replacing a toilet — as long as you’re connecting to existing supply and drain lines or wiring, most jurisdictions don’t require a permit for these.

Minor repairs. Fixing a leaky faucet, patching drywall, replacing a broken window pane, repairing a step — routine maintenance and minor repairs are generally exempt.

Fences under a certain height. Most jurisdictions allow fences up to 6 feet tall without a permit (some allow 7 feet for side and rear yards). Check your local rules.

One-story detached accessory structures. Small sheds and detached structures under a certain size and height are often exempt from permits but typically need to meet setback requirements.

Here’s the thing: the line between “needs a permit” and “doesn’t need a permit” varies by location. A city may require permits for roof replacement while the county next door doesn’t. Always check with your local building department — it’s usually a quick phone call or website lookup.

Who is responsible for pulling the permit?

This is one of the most common questions I get from homeowners. The short answer: it depends on who’s doing the work.

If you hire a contractor

When you hire a licensed contractor, they should pull the permits. In fact, many states require that the contractor pulling the permit be the one doing the work. The permit is tied to the contractor’s license, and they take legal responsibility for the work meeting code.

Here’s why having the contractor pull the permit is almost always the better choice:

Liability. When the contractor pulls the permit, they’re taking legal responsibility for the work. If something goes wrong, it’s on them. If you pull the permit as an “owner-builder,” you’re taking on that liability yourself.

Knowledge and experience. Contractors know what inspectors look for, what documentation is needed, and how to navigate the local building department. They do it every day. You probably don’t.

Inspections. When the contractor pulls the permit, they schedule and manage the inspections. You don’t need to take time off work to meet the inspector.

Cost. Permit fees are usually modest — a few hundred dollars for most residential projects. Building them into the contract keeps everything clean and above board.

If you’re doing the work yourself (owner-builder)

You are legally allowed to pull permits as a homeowner and do the work yourself — or act as your own general contractor and hire subcontractors. This is called being an “owner-builder.”

Before you go this route, understand what you’re taking on:

• You’re responsible for ensuring the work meets code
• You’re liable if something goes wrong
• You schedule and attend all inspections
• You need to provide the plans and documentation the building department requires
• If you sell the house within a certain period (often one to three years), you may need to disclose that you acted as an owner-builder
• Many states restrict how often you can pull owner-builder permits (typically once per year or once per property)

The owner-builder route makes sense if you’re genuinely doing the work yourself. It doesn’t make sense if a contractor suggests it as a way to avoid liability.

Red flag: “You pull the permit, I’ll do the work”

If a contractor asks you to pull the permit and says they’ll do the work, that’s a major red flag. Here’s what that might mean:

• The contractor doesn’t have a license
• The contractor’s license doesn’t cover the type of work they’re proposing
• The contractor doesn’t want the liability of being the permit holder
• The contractor wants to avoid insurance requirements tied to permit-holding

A legitimate, licensed contractor pulls their own permits. Period.

What happens if work is done without a permit?

Let’s say you didn’t get a permit. Maybe you didn’t know you needed one. Maybe the contractor talked you into skipping it. Maybe you’re reading this after the work is already done. Here’s what can happen.

During construction

If an inspector notices work without a permit (from a neighbor complaint, a routine drive-by, or a permit check during another inspection), they can issue a stop-work order. Construction stops immediately. You may face fines, and you’ll need to apply for permits retroactively — which often costs more and involves opening up finished work for inspection.

After construction is complete

Unpermitted work can be discovered when you sell your home. The buyer’s inspection or title search may uncover it. Your options then are:

• Retroactive permits (legalization). You apply for permits after the fact and may need to open up walls or ceilings to prove the work meets code. This is expensive.
• Disclosure. You disclose the unpermitted work to the buyer and adjust the sale price accordingly.
• Removal. In extreme cases, you may be required to remove the unpermitted work entirely.

Insurance implications

If unpermitted work causes damage — a fire from bad wiring, a flood from improper plumbing — your homeowners insurance may deny the claim. They can argue that the work wasn’t done to code and wasn’t inspected, so they have no way of knowing it was done safely. This is not a hypothetical scenario. It happens.

Fines and penalties

Many jurisdictions impose fines for starting work without a permit. These can range from a few hundred to several thousand dollars, depending on the scope of work and whether it’s a first offense. Some cities charge double the original permit fee as a penalty for skipping it the first time.

Common permit myths (debunked)

I hear a lot of misconceptions about permits. Let’s clear up the most common ones.

“My contractor said permits aren’t needed for this type of work.” Contractors say this for three reasons: they don’t know the code (bad), they want to save time (worse), or they want to avoid liability (worst). Always verify with your local building department directly. A quick phone call costs nothing and can save you thousands.

“Permits are too expensive.” Permit fees for most residential projects are a few hundred dollars. Compared to the cost of ripping out unpermitted work, fines, or an insurance claim denial, that’s cheap.

“Permits take too long.” For most residential work, permits are issued in days or weeks, not months. Even if it takes a few weeks, that’s better than a stop-work order halfway through your project.

“If the work is done well, permits don’t matter.” The quality of work and the safety of work are two different things. You can have beautiful tile work hiding dangerous electrical wiring. Permits and inspections catch the things you can’t see.

“Inspectors are just looking for reasons to fail you.” Most inspectors want you to pass. Their job is safety, not punishment. A good inspector will explain what needs to be fixed and how to do it. A failed inspection is usually a learning opportunity, not a catastrophe.

How to check if a permit has been pulled for your project

If your contractor says they’ll pull permits, here’s how to verify it actually happens:

Ask for the permit number. Any contractor who has pulled a permit can give you the permit number immediately. It’s not confidential information.

Check with the building department. Most local building departments have online permit search tools. Enter your address and see what permits are listed. If nothing shows up, call and ask.

Get a copy of the permit. Your contractor should provide you with a copy of the permit and post it at the job site (most jurisdictions require this).

Ask about inspections. Permits come with inspections — typically rough-in inspections for electrical, plumbing, and mechanical, followed by a final inspection. Ask when each inspection is scheduled and what the results were.

Don’t pay for work that requires inspections before the inspection passes. If your contract includes progress payments tied to milestones, make sure those milestones include passed inspections. Don’t pay for rough electrical work until the electrical inspection has passed.

What to do if your contractor starts work without a permit

You’ve just realized the contractor started your kitchen demolition without a permit. Here’s what to do:

Stop the work (if possible). If work has just started, it’s easier to pause and get the permit than to deal with the consequences later. Tell the contractor you want to stop until the permit is in place.

Talk to the contractor directly. Ask why they started without a permit. Their response will tell you everything you need to know. A good contractor will apologize and get the permit filed immediately. A bad one will make excuses.

Call the building department. Ask what you need to do to get a permit for the work that’s already started. Most building departments would rather help you get into compliance than punish you.

Document everything. Take photos of the work that’s been done. Save any text messages or emails about permits (or the lack of them). This documentation is valuable if there’s a dispute.

Consider a different contractor. If a contractor started work without a permit against your wishes, that’s a breach of trust. It may be worth finding someone else for the remainder of the project.

Quick Answers

How much does a building permit cost?

Permit fees vary by location and project value. For most residential projects, expect $200 to $1,500. A kitchen remodel might cost $300-$700; a new deck $150-$400; a bathroom remodel $200-$500. These are estimates — your local building department can give you exact numbers.

How long does it take to get a building permit?

For simple projects (water heater replacement, like-for-like fixture swaps), permits are often issued the same day or within a few days. For more complex projects (structural changes, additions), plan on two to six weeks for plan review and approval.

Can I pull a permit myself as a homeowner?

Yes, in most jurisdictions. You’ll be acting as an owner-builder and taking legal responsibility for the work. This makes sense if you’re doing the work yourself. It’s not recommended if a contractor is doing the work — they should pull the permit.

What’s the difference between a permit and an inspection?

A permit is the approval to do the work. An inspection is the verification that the work meets code. Most permits include multiple inspections — for example, a rough-in inspection after wiring is installed but before drywall goes up, and a final inspection when everything is complete.

Does every contractor need to be licensed to pull a permit?

Yes. In most jurisdictions, only licensed contractors can pull building permits. If a contractor asks you to pull the permit, that’s a sign they may not be properly licensed.

Will skipping a permit affect my home insurance?

It can. If unpermitted work causes damage — like a fire from unpermitted electrical work — your insurance company may deny the claim. Some insurers also ask about permits during the application process and may decline coverage for homes with unpermitted work.

What if a previous owner did unpermitted work?

You’re not automatically liable for a previous owner’s unpermitted work, but it can complicate a future sale. Your options are to get it legalized (retroactive permits), disclose it to buyers, or in some cases, just leave it alone if it’s not causing problems.
