Santa Clarita Building Permits — Cost, Timeline & Process

Building permits in Santa Clarita are administered by the City of Santa Clarita Building & Safety Division. The prior description of Santa Clarita as a contract city using LA County Building & Safety and EPIC-LA for ordinary city building permits was incorrect.

Current Building Codes

For residential and non-residential construction projects submitted on or after January 1, 2026, Santa Clarita enforces the 2025 California Building Standards Code together with City amendments. The current code family includes:

• 2025 California Building Code
• 2025 California Residential Code
• 2025 California Electrical Code
• 2025 California Mechanical Code
• 2025 California Plumbing Code
• 2025 California Fire Code
• 2025 California Wildland-Urban Interface Code
• 2025 California Energy Code
• 2025 California Green Building Standards Code
• City of Santa Clarita amendments

Projects submitted before January 1, 2026 remain subject to the applicable prior-code transition rules.

When You Need a Permit

A building permit is generally required for new construction, additions, structural alterations, regulated electrical/plumbing/mechanical work, pools, many accessory structures, demolition, and other work regulated by the California Building Standards Code and Santa Clarita amendments.

Some minor work can qualify for permit exemptions. Always check the City's current Building & Safety guidance before starting.

Online and Instant Permits

Santa Clarita provides online permit and permit-status services through its Building & Safety systems.

The City also offers Instant Online Permits for qualifying residential work, including selected:

• main electrical panel upgrades;
• water-heater changeouts;
• repipes;
• water-service work;
• rooftop photovoltaic systems; and
• energy-storage systems.

As of May 1, 2026, the City's former PVA permit process is being replaced by MEP permits obtained through Symbium for the affected permit types.

Wildland-Urban Interface and Fire Hazard

Santa Clarita's 2025 code package includes the California Wildland-Urban Interface Code and local amendments. Fire-hazard-zone status can affect materials, exterior construction, vents, roofing, access, and other project requirements.

Use the City's current GIS and Building & Safety guidance to determine the requirements for the specific parcel instead of assuming that every property is subject to the same WUI standards.

ADU Projects

Current California State ADU Law is codified primarily at Government Code §§66310–66342. Qualifying ADU and JADU applications are subject to ministerial review and the applicable state timelines.

Building-code approval, zoning compliance, fire-safety requirements, and other objective standards still apply.

Review Timing

Santa Clarita does not publish one universal permit duration for every project type. Review time depends on project scope, completeness, required Planning or Fire review, and correction cycles.

Qualifying minor residential projects may use instant-permit pathways. For projects requiring plan review, use the City's current permit record and Building & Safety guidance for status.

Typical Process

1. Confirm zoning and parcel constraints with the City of Santa Clarita.
2. Identify the applicable 2025 code requirements and City amendments.
3. Prepare plans and supporting documents.
4. Submit through the City's current permit system.
5. Complete plan review when required.
6. Respond to correction comments.
7. Obtain the issued permit before regulated work begins.
8. Schedule required inspections.
9. Complete final inspection and occupancy/closeout requirements where applicable.

Inspections

The City of Santa Clarita Building & Safety Division performs or administers building inspections for City permits. Required inspection stages depend on the project scope and can include foundation, framing, rough trade, insulation, drywall, energy/WUI-related items, and final inspections.

For current inspection scheduling, use the City's Building & Safety inspection service.
