Los Angeles Building Permits

Los Angeles processes more building permits than any other city in California, handling over 130,000 permit applications annually through LADBS. The department operates multiple district offices throughout the city, with the main office located in downtown LA. Since 2020, LADBS has significantly expanded online permitting capabilities through the BuildLA portal, allowing homeowners and contractors to submit applications, schedule inspections, and track permit status digitally. The city uses a tiered fee structure based on project valuation, with plan check fees typically running 65-75% of the base permit fee.

The LA permit process begins with plan submission through BuildLA or in-person at a district office. Standard residential projects go through plan check review, which takes 4-6 weeks for most projects. Complex projects or those requiring discretionary approvals may take 3-6 months. LADBS offers Express Plan Check for qualifying projects under $500,000 valuation, reducing review time to 2-3 weeks. Once plans are approved, the permit is issued and construction can begin. Required inspections vary by project type but typically include foundation, framing, electrical rough-in, plumbing rough-in, and final inspection.

Standard permit timelines in Los Angeles range from 4-8 weeks for simple projects to 6-12 months for major additions or new construction. Counter permits for minor electrical, plumbing, or mechanical work can often be obtained same-day. ADU permits have been streamlined under state law, with ministerial approval required within 60 days of a complete application. Expedited plan check services are available for an additional 50% fee, cutting review times roughly in half.

In 2024, Los Angeles expanded its Affordable ADU program offering pre-approved plans and reduced fees for income-qualified homeowners. The city also implemented new EV-ready requirements for all new construction and major renovations. LADBS continues to modernize its permitting system, with plans to fully integrate all permit types into BuildLA by 2026.
