Application Process

1. Confirm zoning and project requirements with the Planning Division if the project changes site use, exterior configuration, setbacks, parking, signage, or other land-use conditions.
2. Prepare the permit application and plan set. The City's permit issuance handout says room additions and tenant improvements require three sets of detailed plans; new structures require five complete plan sets plus two sets of soils reports and structural calculations. Grading plans go to Public Works/Engineering, and fire sprinkler plans go to the Fire Department.
3. Submit the application and plans at the Community Development counter during posted walk-in hours. Most permits are issued in person over the counter at City Hall.
4. Pay the required plan check deposit and permit fees. The City accepts cash, check, Visa, or MasterCard for permit-related counter payments.
5. Respond to plan check comments from Building, Planning, Engineering, and Fire as applicable, then obtain permit issuance once approvals are complete.
6. Call the inspection hotline at (909) 625-9448 before required inspections. Requests made before 5:00 p.m. are scheduled for the next business day.

Typical processing time: No general building plan review turnaround is posted on the City website. Permit issuance can be over the counter for qualifying permits; inspection requests made before 5:00 p.m. are scheduled for the next business day.

General Requirements

Montclair regulates construction, enlargement, alteration, repair, moving, removal, demolition, conversion, occupancy, equipment, use, height, area, and other improvements to real property through its adopted Title 24 codes. In practice, most structural, electrical, mechanical, plumbing, reroof, solar, tenant improvement, addition, and new-construction work requires permit review. Exterior changes may also require Planning review.

Required Documents

• Permit application
• project plans sized and detailed for the scope
• plot/site plan
• floor plans
• elevations
• framing/electrical/mechanical/plumbing details
• energy compliance forms where applicable
• soils report and structural calculations for new structures
• grading plans/soils report for projects involving grading
• and fire sprinkler plans when required

Permit validity

Montclair adopted the 2025 California Building and Residential Codes effective January 14, 2026. Those state codes generally provide that permits expire if work is not started within 180 days, or if work is suspended or abandoned for 180 days, unless extended by the building official.

Building code

Ordinance No. 25-1016 adopted the 2025 California Administrative, Building, Electrical, Fire, Green Building Standards, Mechanical, Plumbing, and Residential Codes, plus the 2024 International Property Maintenance Code, effective January 14, 2026.

Owner-builder

Property owners may obtain an owner-builder permit if they are the owners and are doing the work themselves, and they must sign a workers' compensation exemption form.

Contractor requirements

Permits issued to contractors require a valid contractor pocket license copy and proof of workers' compensation insurance. If the license holder does not appear in person, an authorized agent must present the license copy, a signed authorization letter on company letterhead, and workers' compensation information.

Fees

Minimum permit fee

No single universal minimum building permit fee was clearly posted. Many permit categories are flat-fee or table-based; examples include reroof permits starting at $100 and residential photovoltaic permits at $450 for 15 kW or less.

Plan check fee

The permit issuance handout states a plan check deposit is required on all submittals. The Master User Fee Schedule separately lists supplemental plan check at $99 for the first hour and $99 for each additional hour; Engineering plan check fees are also listed for grading, street, sewer, storm drain, and related work.

Permit fee formula

Mixed. Montclair uses flat fees for many common permit types and table-based inspection fees by occupancy/use and size for new construction, tenant improvements, signs, reroofing, solar, and other miscellaneous permits.

Reinspection fee

Compliance inspections, re-inspections, and pre-inspections are listed at $198. The 2025 building code ordinance also states the adopted codes include local fees and penalties, but the City page reviewed did not provide a consolidated penalty table.

Payment note

The City states applicable permit fees are paid in person at City Hall by check, cash, or credit card. Accepted cards listed are Visa and MasterCard.

Fees change. Verify current amounts at the official fee schedule.

Work That Does NOT Require a Permit

• Work that falls under the permit exemptions in the California Building Code and California Residential Code as adopted by Montclair generally does not require a building permit
• Typical state-code exemptions include small detached accessory structures below the code size threshold, certain low fences, certain window awnings, movable cases/counters/partitions below the code thresholds, some finish work, and limited minor repair work
• Certain minor electrical, plumbing, and mechanical repairs may also be exempt where the adopted California codes classify them as ordinary repairs

Important: Even when a building permit is exempt under the adopted state codes, separate Planning, zoning, fire, grading, encroachment, or homeowner association approvals may still apply. Exemptions are narrow and depend on scope, dimensions, location, and whether structural, life-safety, accessibility, energy, or fire-protection systems are affected. Applicants should confirm exemptions directly with the Building Division before starting work.
