Permit and license fees vary widely by location, type of work, and your local government's cost structure

There is no single answer to what a permit costs because each city, county, and state sets its own fees. A plumbing permit in one county might cost $50, while the same work costs $200 in the next county over. Building permits, electrical permits, contractor licenses, and business licenses all have different fee schedules—and those schedules change. What you pay depends on the jurisdiction where the work happens, what kind of work it is, and sometimes how much the project costs.

The fee covers the cost of the inspector who reviews your plans, visits your site, and signs off that the work meets code. It is not a tax or a fine—it is payment for the service of inspection and approval. Some jurisdictions charge a flat fee; others charge based on the square footage of the project, the estimated cost of the work, or the number of fixtures involved.

Key Takeaways

  • Permit fees are set by your city or county, not by the state or federal government, so you must contact your local building department to learn the actual cost.
  • Most jurisdictions charge either a flat fee for straightforward work or a fee based on the project cost, square footage, or number of fixtures—ask which method applies to your project.
  • Contractor licenses and business licenses have separate fee schedules from work permits and may require renewal every one to three years.
  • Some jurisdictions offer reduced fees for homeowners doing their own work, while others charge the same rate regardless of who does the work.

How building departments set permit fees

Your local building department calculates permit fees to cover the cost of plan review, inspections, and administrative overhead. A small jurisdiction with fewer inspectors might charge less per permit than a large city, but that is not always the case—some small towns charge more because they have fewer permits to spread costs across. The fee structure is usually published on the building department's website or available by phone.

Most jurisdictions use one of three methods: a flat fee (the same cost for any permit of that type), a sliding scale based on project cost or square footage, or a per-unit fee (for example, $15 per fixture for plumbing). Some departments combine methods—a base fee plus an additional charge if the project exceeds a certain size or cost. Ask your building department which method applies to your specific project before you assume a cost.

Typical ranges for common permits

Building permits for residential work typically range from $100 to $500 for small projects like a deck or room addition, though large renovations can cost more. Electrical permits often run $50 to $200 depending on the scope. Plumbing permits are usually $50 to $150. HVAC permits fall in a similar range. These are rough figures based on what many jurisdictions charge; your actual cost will depend on your location and the specifics of the work.

Contractor licenses and business licenses are separate from work permits. A contractor license renewal might cost $100 to $500 per year, depending on the trade and your state. A general business license for a home-based business might be $50 to $200 annually. Some states charge based on gross revenue, which means the fee changes year to year. Check with your state licensing board and your local business tax office for the exact amount.

Why the same work costs different amounts in different places

Two neighboring jurisdictions can charge vastly different fees for identical work because they set their own rates independently. A city might charge $300 for an electrical permit while a county 10 miles away charges $75. This happens because each jurisdiction calculates what it costs to run its building department and divides that cost among the permits it issues. A city with more inspectors, more complex code requirements, or fewer permits issued per year will typically charge more.

Some jurisdictions also factor in the cost of code enforcement and complaint investigations. Others charge a lower base fee but add surcharges for expedited review or for work in historic districts. A few jurisdictions offer discounts for homeowners doing their own work, while others charge the same rate regardless of who performs the work. Always ask whether discounts explore to your situation.

How to find out what your permit will cost

Contact your local building department directly—by phone, email, or their website. Have ready a description of the work: what you are building or fixing, the square footage if it is a structure, and the estimated cost if you know it. Some departments have online fee calculators; others will quote you over the phone. A few require you to submit plans before they can give you a final cost, though they can usually give you an estimate based on your description.

If you are hiring a contractor, ask them what the permit cost will be. Many contractors include permit fees in their bid, and they know their local building department's rates. If you are doing the work yourself, call the building department and ask whether homeowner-permits cost the same as contractor permits—some jurisdictions charge less for owner-builders.

What happens if you do not get a permit

Work done without a permit is unpermitted work. If an inspector finds it, the building department can issue a violation, require you to tear out the work and redo it with a permit, or fine you. Unpermitted work can also affect your ability to sell the house—a title search or home inspection may uncover it, and a buyer's lender may refuse to finance a property with unpermitted additions or major systems work. Getting a permit after the fact is possible but more expensive and time-consuming than getting one before you start.

Some minor work—like painting, replacing fixtures, or routine maintenance—does not require a permit in most places. But structural work, electrical work, plumbing, HVAC, and additions almost always do. If you are unsure whether your project needs a permit, ask the building department. That call is free, and it protects you.

Frequently Asked Questions

Can I get a refund if I do not use the permit?

Most jurisdictions do not refund permit fees once issued, even if you decide not to do the work. A few allow you to cancel within a short window (usually 30 days) for a partial refund. Ask your building department about their cancellation policy before you pay.

Do I have to pay the permit fee upfront?

Yes, in nearly all jurisdictions you pay the permit fee when you explore. Some departments accept payment by check, credit card, or in person at the counter. A few allow online payment. The fee must be paid before the permit is issued.

What if the contractor does not pull a permit?

You are responsible for ensuring the work is permitted, even if you hired someone to do it. If the contractor skips the permit to save money, you face the risk of fines and unpermitted work on your property. Always verify that the contractor has pulled the permit before work begins.

Are there any work types that never need a permit?

Minor repairs and maintenance—like replacing a faucet, painting, or fixing drywall—typically do not require permits. But anything structural, anything involving electrical or plumbing systems, or any addition or major renovation does. When in doubt, call your building department.

How long is a permit valid?

Most permits are valid for 6 months to 1 year from the date of issue. If you do not start the work within that time, the permit expires and you must explore again. If work is ongoing, you may be able to request an extension before expiration. Check your permit or ask the building department about the validity period.
