There is no single reliable national price for a building permit, and permit requirements depend on the local authority, project scope, dimensions, and site conditions. Fees may be flat, based on floor area or construction value, or include separate plan-review, inspection, trade, and development charges. Check with the building department or authority having jurisdiction before work begins.
Use local fee schedules and project details—not a national average—to budget. Official examples from Rochester, New York; Portland, Oregon; and Miami, Florida show how rules and charges differ. Toronto’s schedule offers a Canadian comparison, not a U.S. price benchmark.
How Building Permit Fees Are Calculated
Depending on the jurisdiction and project, a permit fee may be a fixed category charge, a rate based on floor area, or a tiered or percentage-based charge tied to estimated or actual construction cost. A project’s total may also include plan review, inspections, separate trade permits, surcharges, or development fees. Not every charge applies to every project.
| Jurisdiction | Fee approach or example | What to keep in mind |
|---|---|---|
| Rochester, New York | The city’s 2026 guidance gives graduated fees based on actual work cost. Examples include $75 for work valued at $0–$2,000; $830 for $48,001–$50,000; and $235 + 0.014 × actual cost for the $60,001–$100,000 tier. | The city says building, electrical, plumbing, license, and certificate fees change effective July 1, 2026. Confirm the applicable schedule and do not extrapolate beyond its posted brackets. |
| Miami, Florida | The schedule adopted April 23, 2026, calculates residential master or trade building permit charges using a schedule-set percentage of estimated construction cost for new construction, additions, and remodeling; residential work under $2,500 has a fixed schedule rate. | Minimum fees and surcharges may apply. The displayed schedule excludes required Florida and Miami-Dade County surcharges. This is a Miami rule, not a national formula. |
| Portland, Oregon | A residential addition may draw charges from building, site-development, plumbing, and electrical fee schedules. | System development charges and other bureau fees may also apply. Ask for an estimate covering the whole project. |
| Toronto, Ontario | The 2026 schedule uses a service index multiplied by area for many project types and lists examination or inspection time at $92.79 per hour. | The schedule lists a $214.79 minimum fee. These are Canadian-dollar amounts and are for comparison only, not U.S. prices. |
Examples and figures above are from the City of Rochester, City of Miami, City of Portland, and City of Toronto schedules and guidance accessed October 5, 2026. Local schedules can change, so confirm the effective date and the amount assessed for your project.

What to Include in a Permit Budget
Ask the local authority which charges apply to your scope. A project may involve some of the following, but not necessarily all of them:
- Building permit and plan-review fees.
- Separate electrical, plumbing, mechanical, demolition, or other permits.
- Inspection or reinspection charges.
- Site-development, utility, school, impact, or system-development charges.
- State, county, or municipal surcharges and taxes.
- Zoning review or a separate zoning permit.
- Deposits, administrative charges, expedited review, or revisions, if listed locally.
- A fee multiplier or penalty if work began before a required permit was issued.
For example, Portland identifies multiple fee schedules and possible system-development charges for additions. Miami’s schedule excludes certain state and county surcharges and describes additional charges for work started without a required permit. Rochester lists distinct trade and other permit-related fees. These are jurisdiction-specific examples, not charges that every project will incur.
Which Projects May Need a Permit?
Permit triggers vary by jurisdiction. Work that changes a building’s footprint or structure commonly needs review, but the exact rules depend on local code, dimensions, scope, and site conditions. Separate building, zoning, electrical, plumbing, or mechanical approvals may apply. Use local examples as prompts for questions, not as nationwide rules.
| Project | Official example | What to verify locally |
|---|---|---|
| Addition or footprint expansion | Portland says enlarging an existing building’s footprint requires a building permit; its guidance also treats a dormer or new second story as an addition. | Building and zoning approvals, drawings, and any applicable trade permits. |
| Carport, garage, or shed | Portland requires a building permit to build, demolish, or alter one if it is greater than 200 square feet measured inside exterior walls, or greater than 15 feet high measured from finish floor to average roof height. | Local size and height thresholds, site placement, and separate electrical, plumbing, or mechanical work. |
| Fence | Portland requires a building permit for a fence taller than seven feet. | Your jurisdiction’s height threshold and any zoning or site restrictions. |
| Deck | Some Portland decks may be exempt from a building permit, but site conditions or placement may still require zoning approval. | Whether the proposed deck qualifies for an exemption and whether separate zoning approval applies. |
| Remodel or trade work | Portland says project-specific requirements vary; separate electrical, plumbing, or mechanical applications may apply. | Whether the scope, systems, or site conditions require building or trade permits. |
Portland’s project guidance says, “Every project is unique; every project has different requirements.” The City of Rochester likewise warns that its common-project list is not all-inclusive and directs people who are unsure to contact its Permit Office.

How to Find Out If Your Project Needs a Permit
- Identify the authority having jurisdiction for the property. This may be a city, county, or another agency; municipal boundaries matter.
- Describe the work precisely, such as an addition, structural change, interior renovation, deck, fence, shed, utility work, demolition, or change of use.
- Prepare the project address, dimensions, estimated value, site conditions, and drawings if available.
- Ask which building, zoning, trade, plan-review, and inspection approvals apply.
- Request a written or official online estimate that accounts for applicable fees and surcharges.
- Ask whether an exemption or fee waiver applies and what conditions or documents it requires.
- Confirm the permit has been issued before starting work, and keep the permit and inspection records.
When asking for an estimate, make clear whether the quoted amount includes plan review, trade permits, inspections, surcharges, and development fees. Portland offers an estimate route and notes that several fee tables may contribute to an addition’s total; Rochester directs uncertain applicants to its Permit Office at 585-428-6526.
Fee Waivers and Penalties Vary by Jurisdiction
Some jurisdictions offer waivers or reductions, and some charge extra when work starts without a required permit. Check the current local rules before relying on either.
Miami’s 2026 schedule describes a 50% reduction in city building permit fees for qualifying residential storm-proofing and sustainability upgrades. It states that the program is scheduled to sunset February 12, 2027, with a possible one-year extension by commission resolution. The schedule also says city building permit fees for solar panels are waived for residential and commercial properties, while state or county surcharges are not included in that waiver. These are Miami-specific, date-sensitive provisions; verify current eligibility and availability with the city.
Portland links to permit-fee waivers based on financial hardship and low income. Verify eligibility and current availability with the city before including a waiver in your budget.
Frequently Asked Questions
How much does a building permit cost?
There is no defensible single price based on the sources reviewed. Fees depend on the jurisdiction and project, and may be based on a category, floor area, or construction value. Additional plan-review, inspection, trade, surcharge, or development charges may apply.
Do I need a permit to remodel my house?
It depends on the work and local rules. Describe the scope, dimensions, and site address to your local building department and ask which building, zoning, and trade approvals apply before starting.
Do I need a permit to build a deck or shed?
Requirements vary. Portland, for example, says some decks may be exempt from a building permit but may still need zoning approval based on site conditions or placement. Its shed rules include size and height thresholds. Do not apply those Portland rules to another jurisdiction; check locally.
Can I start work while a permit is pending?
Confirm with the local authority before starting. Miami’s 2026 schedule describes multiplied charges for work started before a required permit is obtained, illustrating why you should verify issuance and applicable fees first.
How do I get an accurate permit estimate?
Give the authority the project address, precise scope, dimensions, estimated value, and drawings if available. Ask for a written or official estimate that identifies applicable building, zoning, trade, review, inspection, surcharge, and development charges.
