How Much Does a Home Renovation Permit Cost in California?
Last reviewed: August 2026
If you are planning a home renovation in California, one of the first questions you may have is:
“How much will the building permit cost?”
Unfortunately, there is no single permit price that applies to every home renovation in California.
A permit for replacing a few windows may cost very differently from a permit for a major room addition. A kitchen remodel may have different fees from a second-story addition. An ADU, garage conversion, or structural remodel can involve additional reviews and fees.
The reason is simple:
Building permit fees are primarily determined by the local jurisdiction, the type and value of the work, and the reviews required for the particular project.
A homeowner may also encounter several different charges that are collectively referred to as “permit fees.”
This guide explains what homeowners should understand about renovation permit costs, what fees may be included, why prices vary from city to city, and how to budget for permitting before starting a project.
Important: Permit fees change periodically and vary by jurisdiction. The examples in this article are provided to explain how permit fees work and should not be treated as a quote for your project. Always verify the current fee schedule with the city or county responsible for your property before submitting an application.

What Is a Building Permit Fee?
A building permit fee is a charge collected by the city or county for processing and issuing a construction permit.
However, what homeowners often call “the permit fee” may actually consist of several different fees.
Depending on the project and jurisdiction, you may encounter charges for:
- Building permit issuance
- Building plan check
- Electrical permit
- Plumbing permit
- Mechanical permit
- Planning or zoning review
- Fire department review
- Public works review
- Historic review
- Energy-related review
- Records or technology fees
- State-mandated surcharges
- Impact fees
- Other agency fees
Not every project will have all of these charges.
The exact combination depends on the work being proposed and the jurisdiction where the property is located.
If you are unfamiliar with how the overall permitting process works, you may also find our guide on how building permits work helpful.
Is There a Standard California Permit Price?
No.
California does not have one universal residential renovation permit fee.
Local jurisdictions establish their own fee schedules within the applicable legal framework.
That means the permit cost for the same $100,000 renovation could be different in:
- Pasadena
- Los Angeles
- Glendale
- San Marino
- Arcadia
- San Gabriel
- Rancho Cucamonga
- Unincorporated Los Angeles County
- Another California city or county
Even within the same jurisdiction, two projects with similar construction costs can have different total fees if they require different types of review.
For example, a simple interior remodel may not require the same planning, fire, structural, or public works review as a major addition.
This is why a generic online statement such as “California building permits cost $X” should be treated very cautiously.
What Determines Home Renovation Permit Cost in California?
Several factors can affect the total permit cost.
- Project valuation
- Plan-check requirements
- Type of construction
- Electrical, plumbing, and mechanical work
- Planning and zoning review
- Other department reviews
- Impact fees or special charges
- The local jurisdiction
Let’s look at these individually.
1. Project Valuation
Many jurisdictions use the valuation of the proposed construction when calculating building permit and plan-check fees.
Project valuation generally represents the value of the construction work rather than simply the amount you paid a designer.
Depending on the jurisdiction, valuation may be determined using:
- Declared construction value
- Estimated construction cost
- Standard valuation tables
- Building valuation data
- A combination of these methods
For example, Pasadena’s FY 2026 fee schedule uses ICC Building Valuation Data together with gross square footage for valuation estimates for new buildings and structures.
This is important because a homeowner should not assume that the permit fee is simply a percentage of the contractor’s final contract price.
The jurisdiction’s fee schedule determines how the valuation is used.
2. Plan Check or Plan Review Fee
A plan check fee pays for the jurisdiction’s review of the submitted plans.
During plan review, the building department may evaluate whether the proposed project complies with applicable:
- Building codes
- Zoning requirements
- Structural requirements
- Energy requirements
- Fire and life-safety provisions
- Local ordinances
- Other applicable regulations
Some jurisdictions calculate plan-check fees as a percentage of the building permit fee. Others use different formulas.
For example, Los Angeles County’s building code establishes a general plan-check fee equal to 85% of the applicable building permit fee, subject to the County’s stated minimum and other provisions.
This is a good illustration of why the phrase “permit fee” can be misleading.
The building permit itself and the plan review can be separate charges.
If you want to understand what drawings may be required for this review, see our guide to building permit drawings.
3. Building Permit Fee
The building permit fee is generally associated with the actual permit for the construction work.
Many jurisdictions use a tiered fee schedule based on project valuation.
For example, Pasadena’s FY 2026 fee schedule lists building permit fees by valuation, with different rates for different valuation ranges. For projects valued above certain thresholds, the schedule uses a base amount plus an additional amount for each increment of valuation.
This means a project with a higher valuation will generally have a higher building permit fee.
But remember: the building permit fee is not necessarily the total amount you will pay to obtain the permit.
Other charges may be added.
4. Electrical, Plumbing & Mechanical Fees
A renovation may require separate permits or fees for:
- Electrical work
- Plumbing work
- Mechanical/HVAC work
For example, a kitchen remodel may involve new electrical circuits, relocated plumbing, new gas lines, or mechanical ventilation.
A major addition may involve even more systems.
Whether these are included in a combination permit, calculated separately, or handled through additional trade permits depends on the local jurisdiction.
This is one reason two projects with the same construction valuation can have different permit totals.
5. Planning and Zoning Fees
Not every project requires extensive planning review.
But some projects may require planning or zoning review because of:
- Setbacks
- Lot coverage
- Floor area
- Height
- Historic status
- Hillside conditions
- Specific zoning regulations
- Development standards
- Special districts
For example, Pasadena’s current fee schedules include separate planning-related fees for services such as preliminary zoning plan checks and hillside plan checks.
A project requiring additional planning review can therefore cost more than a straightforward building permit.
6. Other Department or Agency Fees
Depending on the project, additional departments may review portions of the application.
- Fire department
- Public works
- Planning
- Historic preservation
- Engineering
- Environmental review
- Transportation
- Utilities
Some jurisdictions separately identify planning, design or historic, fire, and public works plan-check components for valuation-based permits.
This is another reason it is better to think about the total permit-related cost rather than looking only at the building permit line item.
7. Impact Fees and Other Charges
Some projects may also involve additional fees or charges that are not simply building permit fees.
- Development impact fees
- School-related fees
- Utility connection fees
- Transportation-related charges
- Environmental filing fees
- Affordable-housing-related fees
- Other legally applicable charges
These are not automatically applicable to every residential renovation.
A homeowner should therefore ask:
“What fees are required for my specific project?”
rather than simply:
“How much is the building permit?”
Example: How Pasadena Calculates Permit Costs
Pasadena provides a useful example because the City publishes detailed fee schedules.
For FY 2026, Pasadena’s valuation-based building permit schedule includes separate amounts for building permit and plan-check services as well as several departmental review components.
- Building permit
- Building plan check
- Current Planning plan check
- Design and Historic plan check
- Fire Department plan check
- Public Works Department plan check
The schedule also identifies additional charges such as permit issuance and records-system-related charges.
Pasadena also publishes separate planning fees for certain services, such as preliminary zoning plan checks and hillside plan checks.
This demonstrates an important point:
The total cost of obtaining approval can be made up of several different fees.
A homeowner should not look at one line in the fee schedule and assume that it represents the complete permit cost.
Example: Unincorporated Los Angeles County
Unincorporated Los Angeles County uses a different fee structure.
The County’s published building fee schedule uses total project valuation to calculate the building permit fee and also identifies separate plan-check fees and other applicable charges.
The County’s general plan-check fee is calculated at 85% of the applicable building permit fee, subject to the County’s stated minimum and other provisions.
The County also provides for additional charges in certain circumstances when additional plan reviews are required because of changes, omissions, or errors attributable to the applicant.
The County’s fee schedule therefore illustrates why a Pasadena permit estimate should not simply be copied and used for a property in unincorporated Los Angeles County.
The jurisdiction matters.
How Much Does a Home Renovation Permit Cost in California?
This is where homeowners often want a simple answer.
Unfortunately, the most accurate answer is:
It depends on the project.
Here is a better way to think about it.
Kitchen Remodel
A kitchen remodel may involve:
- Building permit
- Electrical permit
- Plumbing permit
- Mechanical permit
- Plan review
However, the total depends heavily on the scope.
Cosmetic kitchen remodel
Replacing cabinets, countertops, flooring, paint, or certain appliances without major utility changes may require little or no building permit in some circumstances.
Structural or utility-heavy kitchen remodel
A project involving wall removal, new windows, new plumbing, new electrical circuits, gas relocation, or structural modifications can require a much more extensive permit application and plan review.
The phrase “kitchen remodel” alone is therefore not enough to estimate the permit fee.
Bathroom Remodel
A bathroom remodel can range from a relatively simple interior renovation to a substantial construction project.
Changing finishes, cabinets, or fixtures can be very different from:
- Relocating plumbing
- Moving walls
- Adding a new bathroom
- Modifying structural framing
- Changing windows
- Adding new electrical circuits
The more extensive the construction work, the more likely the project will require detailed plans and multiple permit components.
Room Addition
A room addition generally requires significantly more documentation than a cosmetic remodel.
Plans may need to show:
- Existing conditions
- Proposed floor plan
- Site plan
- Exterior elevations
- Roof plan
- Building sections
- Structural design
- Energy compliance
- Electrical
- Plumbing
- Mechanical systems
If you want to learn more about the drawings that may be needed for a permit application, see our guide to building permit drawings.
The project valuation will also generally be higher because new construction is being added.
As a result, the permit-related cost is typically more substantial than for a small cosmetic remodel.
Garage Conversion
A garage conversion can have several different permitting considerations.
Depending on the project, you may need to address:
- Building code
- Structural conditions
- Insulation
- Windows
- Egress
- Fire separation
- Electrical
- Plumbing
- HVAC
- Energy compliance
If the garage is being converted into an ADU, additional ADU-specific requirements can apply.
For more information about ADUs and JADUs in California, see our guide to ADU & JADU in California.
The permit cost therefore depends on whether you are simply modifying the garage as part of the primary residence or creating a separate dwelling unit.
ADU Permit
ADU permits deserve special attention because an ADU can involve a complete additional dwelling unit.
Plans may include:
- Site plan
- Existing conditions
- Proposed floor plan
- Roof plan
- Elevations
- Sections
- Structural plans
- Electrical
- Plumbing
- Mechanical
- Energy documentation
California’s ADU laws also contain specific rules concerning fees, including restrictions on certain connection and impact fees depending on the type and size of ADU.
Because ADU laws and local fee schedules change, homeowners should verify the current fee requirements for the specific property and jurisdiction.
For a broader explanation of ADU and JADU definitions, types, state law, and local rules, see our ADU & JADU guide.
Second-Story Addition
A second-story addition can be one of the more complicated residential renovation projects.
In addition to normal building permit fees, the project may involve:
- Structural engineering
- Foundation evaluation
- Planning review
- Zoning review
- Energy compliance
- Fire and life-safety review
- Electrical
- Plumbing
- Mechanical
A second-story addition can therefore have significantly more permitting complexity than a simple interior remodel.
Permit Fees vs. Design and Drafting Costs
This is one of the most important distinctions for homeowners.
Permit fees are not the same as design or drafting fees.
A homeowner may have expenses for:
Design and professional services
- Drafting and design
- As-built documentation
- Structural engineering
- Energy calculations
- Surveying
- Geotechnical services
- Other consultants
Government fees
- Building permit
- Plan check
- Planning review
- Fire review
- Public works review
- Trade permits
- Other applicable charges
These are separate categories of expenses.
For example, if a designer charges $4,000 to prepare a permit plan set and the city charges $2,500 in permit-related fees, the total project pre-construction cost is not $2,500.
It is closer to:
$4,000 design + $2,500 government fees + other required services
This distinction is important when comparing project estimates.
Do Plan-Check Corrections Increase the Permit Cost?
They can.
A first-round plan check does not necessarily mean the project will be approved immediately.
The building department may issue comments or corrections requesting changes to the plans.
Some jurisdictions include a certain amount of review in the original fee structure. Additional reviews, revisions, or services can sometimes result in additional fees, particularly when repeated checks are required because of changes, omissions, or errors.
For example, Los Angeles County’s code provides for additional charges in certain circumstances when additional plan reviews are required because of changes, omissions, or errors on the applicant’s part.
This is another reason that complete and coordinated permit drawings matter.
A well-prepared plan set can help reduce unnecessary back-and-forth during plan check, although no designer can guarantee that a jurisdiction will not issue corrections.
For a deeper explanation of the review process, see our article on how building permits work.
Can You Get a Permit Without Architectural Plans?
Sometimes a very small project may not require the same level of drawings as a major renovation.
However, homeowners should not assume:
“I don’t need a full plan set, so I don’t need a permit.”
These are two different questions.
A project can require a permit even when the drawing requirements are relatively simple.
Conversely, some minor work may not require a building permit at all.
The correct answer depends on:
- Type of work
- Scope
- Existing conditions
- Local regulations
- Building code
- Whether structural work is involved
- Whether electrical, plumbing, or mechanical work is involved
For projects that do require plans, our building permit drawings guide explains the types of drawings homeowners may encounter during the permitting process.
How Can You Estimate Your Permit Cost?
The best way to estimate permit costs is to follow a few steps.
1. Identify the jurisdiction
First determine whether the property is located within a city, unincorporated county, or another permitting authority.
2. Define the project
Determine exactly what you are doing.
- Kitchen remodel
- Bathroom remodel
- Room addition
- Garage conversion
- ADU
- Second-story addition
- Whole-house remodel
3. Determine the approximate project valuation
The jurisdiction may use your declared construction value or its own valuation methodology.
4. Identify required reviews
Ask whether the project requires building, planning, fire, public works, historic, engineering, electrical, plumbing, mechanical, energy, or other reviews.
5. Check the current fee schedule
Use the jurisdiction’s current official fee schedule rather than an old contractor estimate or online article.
6. Ask about additional fees
Specifically ask whether there are technology fees, records fees, state surcharges, impact fees, utility fees, school fees, or special district fees.
7. Ask when fees are due
Some fees may be due at application. Others may be due later in the process.
How Much Should a Homeowner Budget for Permitting?
Instead of setting aside one universal dollar amount, it is better to create a permit budget based on the project.
Your budget should consider:
Government fees
+
Design/drafting
+
Engineering
+
Energy compliance
+
Survey or site information
+
Other consultants
+
Potential plan-check revisions
This gives you a more realistic picture of the pre-construction cost.
For a simple remodel, the government fees may represent a relatively small portion of the total project budget.
For a large addition or ADU, the combined cost of design, engineering, energy documentation, and government fees can be substantially higher.
Common Mistakes Homeowners Make
Mistake #1: Looking for one California-wide permit price
There isn’t one universal residential permit fee.
Mistake #2: Assuming the permit fee equals the total permitting cost
Plan check, planning, fire, public works, trade permits, and other charges may be separate.
Mistake #3: Using an old fee schedule
Cities and counties update their fees. Always check the current schedule.
Mistake #4: Assuming a neighbor’s permit cost will be the same
Even similar houses can have different project scopes and review requirements.
Mistake #5: Confusing design fees with permit fees
Your designer’s fee and the government’s permit fee are completely different expenses.
Mistake #6: Underestimating engineering and other consultants
A project may require structural engineering, energy documentation, surveying, geotechnical work, or other professional services.
Mistake #7: Assuming a permit guarantees approval
Paying a permit fee does not mean the plans automatically comply with every applicable requirement.
The plans still have to go through the applicable review process.
What Should You Do Before Submitting Your Plans?
Before submitting a renovation permit application, it is helpful to have a clear understanding of both the project and the expected costs.
Step 1: Confirm your project scope
Know exactly what you are changing.
Step 2: Identify the jurisdiction
Determine which city or county is responsible for the property.
Step 3: Check zoning and planning requirements
This is especially important for additions, ADUs, second stories, and projects that change the exterior.
Step 4: Determine what drawings are required
The permit package may need more than a floor plan.
Step 5: Prepare accurate plans
Existing conditions and proposed work should be clearly documented.
Step 6: Coordinate structural and other supporting documents
Don’t wait until after the permit plans are finished to discover that structural or energy documentation is required.
Step 7: Check the current fee schedule
Use the jurisdiction’s official fee schedule.
Step 8: Budget for the entire permitting process
Think beyond the building permit itself.
For a better understanding of the drawings that may be needed before submission, see our building permit drawings guide.
Why Permit Costs Should Not Be the Only Thing You Compare
When homeowners compare renovation proposals, they sometimes focus heavily on the permit fee.
But the government fee is only one part of the process.
“What will it take to get the project properly designed, submitted, reviewed, and approved?”
A very inexpensive plan set may result in:
- Missing information
- Multiple corrections
- Delays
- Additional consultant costs
- More plan-check cycles
- Construction changes
On the other hand, a properly coordinated plan set can make the permitting process more predictable.
There is never a guarantee that a project will receive approval without corrections, because the final determination belongs to the reviewing jurisdiction.
But good preparation can reduce avoidable problems.
Final Takeaway
There is no single answer to the question:
“How much does a home renovation permit cost in California?”
The better question is:
“What fees will apply to my specific project in my specific jurisdiction?”
Permit costs can depend on:
- Project valuation
- Type of construction
- Building permit fees
- Plan-check fees
- Electrical, plumbing, and mechanical work
- Planning and zoning review
- Fire review
- Public works review
- Historic review
- Impact fees
- Utility charges
- Other jurisdiction-specific requirements
For example, Pasadena’s current fee schedules use valuation-based building permit fees and separately identify several plan-check and departmental charges.
Unincorporated Los Angeles County uses a different valuation-based fee structure and separately calculates plan-check fees and applicable charges.
So if you are planning a renovation, addition, garage conversion, ADU, or other residential project, don’t rely on a generic online permit-cost estimate.
Identify the jurisdiction, define the project, determine the required reviews, and check the current official fee schedule.
And remember:
Permit fees are only one part of the cost of getting a project ready for construction.
The complete budget may also include drafting, engineering, energy compliance, surveying, geotechnical work, and other professional services.

Important Update Note
Last reviewed: August 2026
Permit fee schedules can change periodically, and different jurisdictions use different methods to calculate and collect fees.
The examples in this article are based on official fee information available at the time of review, including current 2026 Pasadena information and published Los Angeles County fee information.
For a specific project, homeowners should verify the current fees directly with the jurisdiction having authority over the property before submitting an application.
CADnest Design prepares plans based on the laws, codes, and jurisdictional requirements in effect at the time of drafting. Permit fees and final fee calculations are determined by the applicable jurisdiction, and the final determination of required fees and permit approval rests with the authority having jurisdiction (AHJ).
