Folsom Building Department 2026: Permits, Inspections & Services

Folsom Building Permits, Inspections & City Services

If you are remodeling a home, replacing HVAC equipment, reroofing, installing an EV charger, building an addition, constructing an ADU, adding a pool, starting a commercial project, or trying to close an existing permit in Folsom, California, the City of Folsom Building Services Division is the main office for building permits, plan review and construction inspections inside city jurisdiction.

Folsom Building Department Contact Information

The building-permit function is handled through the City of Folsom Community Development Department’s Building Services Division. Building Services reviews plans for code compliance, issues residential and commercial permits, performs required inspections and answers building-code questions.

Do not rely only on a “Folsom” mailing address. If you are unsure whether the property is actually under City of Folsom permitting jurisdiction, give the Building Counter the exact street address before preparing a full permit package.

Do You Need a Folsom Building Permit?

A permit is commonly required when work affects a building’s structure, electrical system, plumbing, mechanical equipment, life-safety systems, occupancy, energy systems or other regulated components. The exact requirement depends on the work rather than simply its cost.

If your project is unusual, describe the entire scope when contacting the City. For example, saying “bathroom remodel” is less useful than saying “replace shower, move toilet drain, relocate electrical outlets and remove one wall.” That helps staff identify the correct permit path.

Minor Permit or Major Permit?

Folsom separates many building applications into Minor Permits and Major Permits. Choosing the correct path matters because the review process is different.

Minor permits

The City’s current Minor Permit guidance describes these as projects needing minimal plan review. A complete qualifying minor permit may be issued electronically through eTRAKiT, and the City’s handout states that minor permits can generally be issued within approximately 1–3 days of submittal when the submission is complete.

Examples listed by Folsom include:

• HVAC changeouts
• Water heater replacements
• Reroofing
• EV chargers
• Window replacement without structural work
• Some kitchen and bathroom remodels without structural work

Major permits

A major permit typically needs plan review by one or more City divisions. Folsom identifies projects such as new homes, commercial buildings, additions, ADUs, pools, photovoltaic systems, patio covers, retaining walls, sheds or pool houses, fire systems and signs among examples that can require the major-permit process.

For new applications, Folsom moved the major permit workflow to eTRAKiT beginning October 20, 2025. Older applications already being processed before the transition may remain in the previous ProjectDox workflow until approved.

How to Apply for a Folsom Building Permit Online

1. Confirm the project scope.
   Write down exactly what you are constructing, removing, replacing or changing. Include structural, electrical, plumbing and mechanical work.
2. Open the City’s ePermit Center.
   Use the official Folsom ePermit Center to review the City’s current process before starting the application.
3. Create or sign in to eTRAKiT.
   Go to Folsom eTRAKiT. A property owner or other public applicant can create a public account. Licensed contractors should use the contractor-registration process.
4. Start the correct permit application.
   Enter the project address, applicant information and a complete description of work. Do not choose a permit type simply because its name looks close to your project.
5. Upload the required documents.
   Add plans, calculations, specifications, Title 24 documents and other project-specific attachments requested for the permit type.
6. Submit the application.
   For a major permit, City staff perform a completeness check before routing plans for formal review.
7. Pay initial or plan-review fees when requested.
   Open your eTRAKiT dashboard and select the fee amount associated with the application.
8. Respond to correction comments.
   If reviewers request changes, revise the drawings and supporting documents carefully. Answer every correction rather than uploading a partially updated plan set.
9. Pay permit-issuance fees.
   When approvals are complete, the City calculates the remaining issuance charges. Pay them through eTRAKiT when the invoice appears.
10. Download the issued permit and approved documents.
    Do not begin regulated construction merely because plans were submitted or approved for review. Wait until the permit is actually issued.

What to Prepare Before You Submit

The exact plan package depends on the project. Preparing the complete package before clicking submit can prevent avoidable completeness-review delays.

Folsom Building Permit Fees in 2026

There is no single flat price for a Folsom building permit. The amount can depend on construction valuation, permit type, plan review, inspections, planning or engineering review, development impact fees and state or outside-agency charges.

The City publishes current Community Development fee information and a Master Fee Schedule. The City’s current finance page identifies its Master Fee Schedule as effective July 1, 2026.

How to get a useful fee estimate

1. Open the official Community Development fee page.
2. Select the current fee schedule that applies to the property and project.
3. Identify whether your project has a valuation-based building permit fee.
4. Add applicable plan-review and processing charges.
5. Check whether Planning, Engineering, Fire, impact or other agency fees apply.
6. For a project-specific figure, provide Building Services with the address and complete project description.

Paying fees through eTRAKiT

For an active permit:

1. Sign in to eTRAKiT.
2. Open My Dashboard.
3. Select the amount shown in the Fees Due column.
4. Review the shopping cart.
5. Proceed to checkout.
6. Select the available payment method and complete payment.
7. Save the emailed or printable receipt.

Payment-service charges can change. Review the amount shown by the official checkout screen before submitting payment.

How to Schedule a Folsom Building Inspection

Building inspections are scheduled online through eTRAKiT. The City states that its old automatic phone scheduling system is no longer used.

Schedule an inspection step by step

1. Make sure the permit is issued. An application that is still under review cannot proceed like an active construction permit.
2. Find the permit number. In eTRAKiT, choose Permits → Search for a Permit and search by address.
3. Open the issued permit.
4. Review the preloaded inspection list. Folsom places required inspection types on the permit.
5. Select the inspection you are ready for.
6. Choose an available date and submit the request.
7. Keep the approved plans and permit available at the job site.

Before the inspector arrives

• Make sure the requested work is complete and visible.
• Do not cover framing, wiring, plumbing, reinforcement or other work that requires inspection.
• Keep the permit and approved plans available.
• Provide safe access to the work area.
• Complete previous correction items before requesting reinspection.
• Confirm that the inspection requested matches the stage of construction.

Need to cancel an inspection?

The City allows applicants to cancel through eTRAKiT or contact the Building Counter at EPC@folsom.ca.us. Folsom also publishes individual inspector contacts on its inspection page.

What Building Code Does Folsom Use in 2026?

Folsom states that the 2025 California Building Standards Code, Title 24 became effective January 1, 2026. New building permit applications submitted on or after that date must generally comply with the 2025 code cycle along with Folsom’s applicable local requirements.

The statewide code family can include building, residential, electrical, mechanical, plumbing, energy, fire, existing-building, CALGreen and other Title 24 requirements depending on the project.

For a plain-English explanation of the statewide code cycle, see our California Building Code 2026 guide. You can also review our city building code guide to understand how statewide standards and local amendments work together.

For a Folsom project, however, the City’s adopted rules and project-specific review control. Start with the official Folsom Building Services page.

Special 2026 Situations Worth Knowing

ADUs

Folsom updated its ADU requirements in 2026. A building permit is required for an ADU, and the City now handles applicable design review as part of the building-permit review rather than making every qualifying project complete a separate public-hearing process.

Before designing an ADU, use the City’s current ADU checklists and workbooks rather than an older third-party checklist. Planning questions go to PlanningEPC@folsom.ca.us or 916-461-6202; building-permit questions go to EPC@folsom.ca.us or 916-461-6201.

Residential solar and battery projects

Folsom has an Instant Solar Permitting process through Symbium for eligible residential solar and battery projects. Applicants complete the qualifying solar application in Symbium and use eTRAKiT for applicable City permit-fee payment and final permit documents.

Review Folsom’s Instant Solar Permitting instructions ↗

Fire permits and fire inspections

Some commercial construction and fire-protection work also involves the Folsom Fire Prevention Division. Fire plan review or construction inspection requirements can apply separately from ordinary building inspections, so do not assume a building inspection automatically clears the fire portion of a project.

Folsom Permit Expiration and Extensions

Permit deadlines are easy to miss when a project pauses.

• Folsom states that a building permit application expires 180 days after filing if a permit has not been issued, subject to applicable rules.
• Under current state-law rules described by the City, an issued permit can expire if qualifying work does not begin within the required period or if too much time passes between required approved inspections.
• Folsom’s Municipal Code also establishes a two-year permit-expiration provision.
• The City states that a one-time 180-day extension may be granted when a written request is made before expiration and justifiable cause is shown.

Common Problems and the Best Next Step

Before You Start Construction
