Santa Clarita Local Requirements

While California state law provides baseline regulations, Santa Clarita may have additional local requirements. GatherADU's team stays current with Santa Clarita's specific zoning codes, architectural guidelines, and permit processes to ensure your ADU project meets all requirements.

Common local considerations in Santa Clarita include:

• Design review requirements and architectural standards
• Utility connection fees and impact fees
• Fire department access requirements
• Neighborhood-specific overlay zones

California law (AB 68, AB 881, SB 9, and subsequent legislation) guarantees your right to build ADUs. Cities cannot:

• Require owner-occupancy for ADUs permitted after 2020
• Require additional parking for ADUs near transit
• Charge impact fees for ADUs under 750 sq ft
• Deny ADUs that meet state minimum standards
• Impose lot coverage limits that prevent a 800 sq ft ADU

If you believe your ADU application is being unfairly denied, California HCD can intervene on your behalf.
