Application Process

1. Confirm the project requires a permit and download the applicable forms and handouts from the City's Applications and Online Documentation page.
2. For eligible permit types, apply through the Citizen Access Portal; for other projects, submit the plan check and permit application and supporting plans/documents to Building and Safety. Applicants can also make an appointment with a Permit Technician in Room 12.
3. Building and Safety reviews the application, and other City departments may also review plans for compliance with laws under their jurisdiction. Some minor project types may qualify for over-the-counter plan review, subject to staff approval and complete submittal.
4. Pay required fees. The Building Official issues the permit after confirming code compliance and payment of required fees.
5. Keep the approved plans on site, complete the work, and request required inspections online or by email. Final inspection is required for the permit to be complete.
6. If work must be done in an emergency, submit the permit application by the next working business day.

Typical processing time: No general citywide turnaround is published. Norwalk states certain smaller project types may qualify for over-the-counter plan review.

General Requirements

Norwalk requires a permit before an owner or authorized agent constructs, enlarges, alters, repairs, improves, moves, demolishes, or changes the use/occupancy of a building or structure, performs grading, or installs/replaces regulated electrical, gas, mechanical, or plumbing systems. The Building and Safety page also states permits are required for new construction, modifications to existing development, and most plumbing, mechanical, and electrical improvements.

Required Documents

• Typically a completed plan check and permit application plus plans, specifications, computations, and other supporting data required by the Building Official. Depending on project type, Norwalk also posts residential and commercial plan review requirements, agency approval checklists, owner-builder declaration forms, and trade-specific handouts/checklists on its Applications and Online Documentation page.

Permit validity

Permit applications are deemed abandoned after 180 days unless pursued in good faith or a permit is issued; the Building Official may grant extensions of up to 90 days each. Issued permits expire if work does not start within 12 months, or if work is suspended/abandoned for 180 days. Extensions may be granted in writing for up to 180 days each with justifiable cause.

Building code

Norwalk adopted the 2025 California Building Code, based on the 2024 International Building Code, plus local amendments. The city also states it adopted CALGreen and enforces other state and city codes through Title 15.

Owner-builder

A permit may be issued to the property owner shown on the grant deed. The owner must show California ID and sign an Owner Builder Declaration accepting responsibility for the project. Norwalk states electrical permits must be issued to a C-10 licensed contractor.

Contractor requirements

Contractors must obtain a City business license, show their state pocket license, and show workers' compensation coverage.

Fees

Minimum permit fee

$95 base building permit fee under the valuation table for projects valued from $1 to $2,000. Norwalk also lists a $95 permit issuance fee.

Plan check fee

Standard building plan review fee is 85% of the permit fee when applicable. Expedited plan check is 1.5x the standard plan check fee. Over-the-counter plan review is listed at 65% of permit-related plan review charges, with hourly billing in 15-minute increments for applicable OTC review.

Permit fee formula

Mixed. Norwalk uses flat fees for many common permit types, a valuation-based table for new buildings/additions/TI/residential remodels, and an alternative inspection-count table for stand-alone or combination permits not otherwise listed.

Reinspection fee

Reinspection fees apply after the first reinspection per the adopted fee schedule.

Penalty (no permit)

Investigation fees apply for work done without permits, in addition to regular permit fees.

Payment note

Norwalk's fee schedule notes that additional permit processing fees, planning review fees, and fees collected on behalf of other agencies may apply. Valuation may be adjusted by the Building Official using ICC or Marshall Swift valuation data if the application valuation is underestimated.

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