City of Mission Viejo

Mission Viejo requires a building permit for constructing, moving, altering, converting, improving, repairing, or demolishing a structure within the city, subject to listed exemptions. The city's exempt-work handout cites Mission Viejo Municipal Code Title 8, Chapter 8.02 and CBC Section 105.2.

• Exempt Countertop replacement where no drywall is removed or reinstalled
• Exempt Decorative finish work such as carpet, linoleum, tile, painting, or cabinet door-only replacement
• Exempt Appliance repairs that do not alter the original appliance rating
• Exempt Like-for-like replacement of electrical breakers and fuses
• Exempt Replacement of existing outlets and switches without modifying the box
• Exempt Faucet or toilet repair or replacement without changing locations
• Exempt Roof repairs or replacements under 10% of total roof area, with no framing changes
• Exempt Awnings projecting no more than 54 inches from exterior walls
• Exempt Detached one-story accessory structures of 120 square feet or less, with no electrical or plumbing
• Exempt Driveways and walkways not more than 30 inches above grade
• Exempt Fences or garden walls not exceeding 6 feet in height
• Exempt Retaining walls not exceeding 3 feet in height
• Exempt Portable electrical or mechanical equipment
• Exempt Minor repair of 3 or fewer electrical outlets or lights
• Exempt Clearing plumbing stoppages where no pipes inside walls or underground are replaced

Note: The city's handout states permit exemptions do not authorize work that violates code or other laws, and other approvals such as zoning, grading, or environmental review may still apply. Work affecting structural integrity still requires a permit. The exempt-work handout was updated May 20, 2025 and cites CBC 2022 Section 105.2; Mission Viejo has since adopted the 2025 code editions in Municipal Code Section 8.02.010.

Building code

Mission Viejo Municipal Code Section 8.02.010 adopts the California Building Code, California Residential Code, California Electrical Code, California Plumbing Code, California Mechanical Code, California Energy Code, California Green Building Standards Code, California Historical Building Code, California Existing Building Code, California Referenced Standards Code, and International Swimming Pool and Spa Code, 2025 editions.

Permit validity

Mission Viejo charges a $35 plan review or permit extension fee, a permit-renewal fee equal to 35% of the building or MEP fee, and a plan-review renewal fee equal to 100% of the plan review fee. The public city pages reviewed confirm extensions and renewals are part of the process, but they do not restate the exact expiration period on the pages reviewed.

Owner-builder

Homeowners pulling permits must use the owner-builder disclosure path and submit an Owner Builder Notification where required. The city's owner-builder declaration cites Business and Professions Code Sections 7031.5 and 7044 and states owner-builders must either perform the work themselves or through employees on work not intended for sale, or contract exclusively with properly licensed contractors.

Contractor requirements

The city requires contractor permit disclosure forms and, when applicable, a contractor pocket card or letter of authorization. Mission Viejo's owner-builder declaration also requires permit applicants to state either their contractor license number and that it is in full force and effect, or the legal basis for exemption.
