Temecula Local Requirements

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

Common local considerations in Temecula include:

• Design review requirements and architectural standards
• Utility connection fees and impact fees
• Fire department access requirements

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

• Require additional parking for ADUs near transit
• Charge impact fees for ADUs under 750 sq ft
• Deny ADUs that meet state minimum standards
