Quick answer
There is no single national building permit cost in 2026. The amount you pay depends on the local government, project type, project value or size, plan review, inspections, and other fees that apply to your project.
A small residential project may have a relatively simple fee structure, while a new home, large addition, or complex remodel can involve several separate charges.
Before starting a home improvement project, many homeowners ask the same question: How much does a building permit cost?
The answer is more complicated than one national dollar amount. Building permits are generally issued by local governments, and each jurisdiction can establish its own fee schedule.
Some jurisdictions calculate fees from the value of construction. Others use square footage, fixed fees, project type, occupancy, construction type, or a combination of several methods.
You may also see separate charges for plan review, inspections, zoning review, technology services, impact fees, development fees, or trade permits.
This guide explains the major factors behind building permit fees in 2026 and gives examples from current municipal fee schedules so you can understand how the calculation works.

Is There an Average Building Permit Cost in 2026?
Not in a way that can reliably predict the cost for every property in the United States.
A national average can be useful for general planning, but it can also be misleading because permit systems are local.
For example, Seattle says permit costs can depend on the size and complexity of the project, the value of the work, additional permits, plan review time, inspections, and technology fees.
Portland's 2026 fee schedule uses a valuation-based system for residential building permits and separately lists development services and plan review charges.
Phoenix also uses valuation-based building safety permit fees for new construction, additions, and remodels.
Location
The city or county sets the local fee schedule.
Project
A deck, remodel, addition, garage, and new home can have very different fee calculations.
Valuation
Some jurisdictions use the value of construction to determine permit fees.
Because of these differences, it is better to think of permit costs as a local calculation rather than a universal price.
How Are Building Permit Fees Calculated?
Most permit fee systems fall into a few common categories.
1. Project valuation
The jurisdiction calculates the value of the work and applies a fee schedule. The valuation may be based on the applicant's declared cost, a locally adopted valuation table, or whichever method the local rules require.
2. Square footage
Some fee calculations use the size of the building, addition, garage, or other permitted structure.
3. Fixed or minimum fees
Small projects may have a minimum fee even when the construction value is low.
4. Plan review
A jurisdiction may charge separately for reviewing drawings, structural plans, site plans, or other submitted documents.
5. Inspections
Some jurisdictions include a number of inspections in the base fee. Additional or special inspections can create additional charges.
The permit fee may not be the total project approval cost
A permit application can involve multiple charges. Before budgeting, ask the local authority whether plan review, zoning review, inspections, impact fees, development fees, and trade permits are included or billed separately.
Building Permit Cost by Project Type
The type of project can have a major effect on the permit fee. A small accessory structure does not necessarily use the same calculation as a new home or major addition.
| Project | What Can Affect Cost | Common Additional Fees |
|---|---|---|
| New home | Valuation, square footage, occupancy, construction type, plan review | Trade permits, inspections, impact or development fees |
| Home addition | New floor area, project valuation, structural review | Electrical, plumbing, mechanical, zoning |
| Garage | Size, valuation, detached or attached construction | Site review, electrical, zoning |
| Deck | Size, height, structure, location and local rules | Plan review, zoning or inspections where applicable |
| Shed | Size, height, location and whether a permit is required | Zoning or site-related charges where applicable |
| Remodel | Value of work and structural changes | Trade permits, plan review and inspections |
This table is a planning guide, not a fee schedule. Some projects may be exempt from a building permit while still being subject to zoning or other approvals. Other projects may require multiple permits.
Why Building Permit Costs Vary by Location
The same $50,000 home improvement project can produce different permit fees in different cities.
This happens because building departments have their own ordinances, fee schedules, valuation methods, administrative systems, and inspection structures.
Seattle's 2026 fee information, for example, states that permit cost can depend on project size and complexity, value of work, additional permits, review time, inspections, and technology fees.
Seattle also implemented 2026 fee changes. The city reported a 6.5% year-over-year inflationary increase to most fees and an 18% increase to construction permit and Master Use Permit fees.
This illustrates why an old permit-cost article can become inaccurate even when the basic permit process has not changed.
Always check the current fee schedule
A fee schedule from 2024 or 2025 may not be the fee schedule used in 2026. Before budgeting for a project, check the current local fee schedule or confirm the fee with the permitting department.
Portland, Oregon: 2026 Building Permit Fee Example
Portland provides a useful example because its 2026 fee schedule shows how a valuation-based system can work.
The City's residential development services fee schedule, effective July 10, 2026, starts with a minimum fee of $21.19. For construction values from $2,001 through $25,000, the schedule lists a $35.74 charge for the first $2,000 plus $3.74 for each additional $1,000 or fraction thereof through $25,000.
| Construction value | Published residential fee component |
|---|---|
| $1–$500 | $21.19 minimum |
| $501–$2,000 | $21.19 + $0.97 per additional $100 |
| $2,001–$25,000 | $35.74 + $3.74 per additional $1,000 |
| $25,001–$50,000 | $121.76 + $2.81 per additional $1,000 |
| $50,001–$100,000 | $192.01 + $1.88 per additional $1,000 |
| $100,001+ | $286.01 + $1.58 per additional $1,000 |
These are not necessarily the final charges a homeowner will pay. Portland's schedule separately identifies the building permit fee and plan review/process fee, along with other possible charges.
For example, the 2026 schedule lists a residential building permit fee starting at $167 for construction values of $1 to $500. It then increases according to the project's calculated permit valuation.
Portland also states that its structural permit valuation for new construction and additions can use the ICC Building Valuation Data Table and that the calculated valuation or the applicant's stated value, whichever is greater, can be used under its methodology.
Phoenix, Arizona: 2026 Valuation-Based Permit Fees
Phoenix provides another clear example of a valuation-based permit system.
The city's development fee information lists building safety permit fees for new construction, additions, and remodels. The fee calculation is based on project valuation.
The published schedule states that valuation can be based on building square footage multiplied by a standard rate for the occupancy. It also explains that minimum valuation can be determined by the Building Official using nationally recognized standards.
What this means for homeowners
You cannot always assume that the number on your contractor's estimate is the exact number the city will use to calculate the permit fee.
Some jurisdictions use their own valuation tables or minimum valuations. The permitting authority may therefore calculate a permit value differently from the retail project price.
This is one reason it is important to check the local fee schedule before assuming that a percentage of your contractor's quote will equal your permit cost.
Seattle, Washington: 2026 Building Permit Fees
Seattle's 2026 guidance gives another useful example of how several factors can influence permit costs.
The city states that permit cost can depend on:
- The size and complexity of the project
- The value of the work
- Additional permits
- Plan review
- Inspection fees
- Technology fees
Seattle's 2026 fee changes also demonstrate how quickly local permit costs can change. The city reported that most fees received a 6.5% inflationary increase for 2026, while construction permit and Master Use Permit fees increased 18% year over year.
Lesson from Seattle
Searching for an old "Seattle building permit cost" article may not give you the current answer. Always look for the current year's fee code or official fee estimator.
Additional Building Permit Fees You May Need to Budget For
The basic building permit fee is only one possible part of your total permitting expense.
Plan review fee
Charged for reviewing plans and documents where the local fee schedule requires it.
Inspection fee
Some jurisdictions include inspections while others may charge separately for certain inspections or additional inspections.
Zoning or land-use review
A project may need zoning review in addition to a building permit.
Electrical permit
Electrical work may require its own permit depending on the jurisdiction.
Plumbing permit
New or modified plumbing can require a separate trade permit.
Mechanical permit
HVAC and mechanical work can have separate permitting requirements.
Development or impact fees
Some projects may trigger development, infrastructure, or impact-related charges.
Reinspection fees
Failed or additional inspections can create extra charges under some local fee schedules.
Does the Cost of Construction Affect the Permit Fee?
Often, yes.
Many jurisdictions use a valuation-based system. In simple terms, the more valuable the permitted work is, the higher the fee can become.
But this does not mean every city simply charges a fixed percentage of your contractor's invoice.
A jurisdiction may use a fee table with different rates at different valuation levels. It may also use a standard construction valuation table rather than the exact amount stated on your estimate.
Do not understate project value just to reduce the permit fee
Permit applications should contain accurate project information. Some jurisdictions have their own methods for determining or verifying construction value.
How Much Does a Home Renovation Permit Cost?
Home renovation permit costs depend on what you are changing.
Replacing finishes may have different requirements from removing walls, changing structural framing, adding square footage, relocating plumbing, installing new electrical circuits, or changing the use of a room.
A renovation involving multiple trades can therefore require several permits instead of one simple building permit.
Before starting a major remodel, ask the local permitting department which permits apply to each part of the work.
How Much Does a Permit Cost for a Deck, Shed, or Garage?
There is no universal permit price for these projects either.
A deck permit may depend on the deck's size, height, structure, attachment, and location. A shed may be permit-exempt in one jurisdiction but require approval in another. A garage can involve building, zoning, setback, foundation, electrical, and other requirements.
This is why a homeowner should not choose a project budget by searching for one national "deck permit cost" or "garage permit cost" number.
Deck
Check height, size, setbacks, attachment and local permit requirements.
Shed
Check size exemptions, height, placement and zoning.
Garage
Check setbacks, foundation, structure, size, zoning and applicable trade work.
How to Avoid Unexpected Building Permit Costs
The best way to control permit costs is to understand the complete fee structure before submitting your application.
Confirm the authority
Determine which city, county, township, or other authority regulates the property.
Identify every permit
Determine whether building, electrical, plumbing, mechanical, zoning, or other approvals are needed.
Ask how valuation is calculated
Find out whether the authority uses your stated construction value, a standard valuation table, square footage, or another method.
Check plan review charges
Ask whether plan review is included in the permit fee or charged separately.
Check inspection and reinspection fees
Find out how many inspections are included and what happens if additional inspections are required.
Find out what permit requirements may apply to your property.
Permit costs are only one part of the process. Your address, municipality, project type, zoning, setbacks, and local requirements can all affect what you need before construction.

Frequently Asked Questions
How much does a building permit cost in 2026?
There is no single national building permit cost in 2026. Local governments set their own fees. Depending on the jurisdiction and project, fees can include a permit fee, plan review fee, inspection charges, technology fees, zoning fees, impact fees, and separate trade permits.
What determines the cost of a building permit?
Building permit costs may depend on project valuation, square footage, project type, construction type, occupancy, location, plan review requirements, inspections, zoning review, and additional permits required for electrical, plumbing, mechanical, or other work.
Is a building permit fee based on the cost of construction?
In many jurisdictions, yes. Some cities use the declared or calculated project valuation to determine permit fees. Other jurisdictions may use square footage, fixed fees, or a combination of methods.
How much does a permit cost for a home addition or remodel?
The cost depends on the local fee schedule and the size and value of the work. A larger addition may have higher valuation-based fees and additional plan review or inspection charges. A small remodel may use a lower fee or a different calculation.
Are building permit fees the same in every city?
No. Building permit fees are local. Cities and counties can use different fee schedules, valuation methods, minimum fees, plan review charges, inspection fees, and additional charges.
Final Answer: How Much Should You Budget for a Building Permit?
The most accurate answer to "How much does a building permit cost?" is: it depends on the project and the local jurisdiction.
Do not use one national number as your final budget. Instead, identify the authority that regulates your property, determine which permits are required, and check the current fee schedule.
Ask whether the fee is based on construction value, square footage, project type, or a fixed schedule. Then check for separate plan review, inspection, zoning, development, electrical, plumbing, mechanical, or other charges.
Before applying for your permit, check these five things
- Which local authority issues the permit?
- What permits are required for the complete project?
- How does the authority calculate project valuation?
- Are plan review and inspection fees included?
- Are there additional zoning, development, impact, or trade fees?
