Los Angeles Building Permit Guide 2026 — What Every Homeowner Needs to Know
One of the most confusing aspects of construction in Greater Los Angeles is figuring out which building department handles your property — and what permits you actually need. Los Angeles County contains 88 cities. Many have their own independent building departments. The rules, fees, and timelines vary significantly from city to city. This guide gives you a clear map of the LA permit landscape so you go into your project informed.
The Big Misconception: “LADBS Handles All of LA”
Many homeowners assume the Los Angeles Department of Building and Safety (LADBS) handles all construction permits in the Los Angeles area. It doesn’t. LADBS only covers properties within the incorporated City of Los Angeles. Many cities within Los Angeles County operate completely independent building departments.

ADU Permit Process in Los Angeles — Step by Step
- Site evaluation and feasibility: APLA assesses your lot, confirms setbacks, coverage, and ADU type eligibility
- Architectural drawings: ADU floor plans and elevations prepared and submitted with permit application
- Plan check submission: Submitted to LADBS or your city’s building department
- Plan check review: 45–70 days at LADBS under the state’s 60-day ADU mandate; independent cities vary
- Corrections (if any): Plan checker may request changes or clarifications — APLA responds and resubmits
- Permit issuance: Building permit issued; construction can begin
- Construction inspections: Foundation, framing, MEP rough-in, insulation, drywall, and final
- Certificate of Occupancy: Issued after final inspection; ADU is now legal and rentable
How Much Do Building Permits Cost in Los Angeles?
Permit fees in Los Angeles are based on the estimated value of construction. General ranges:
- Kitchen remodel (City of LA): $1,500–$4,000
- Bathroom remodel (City of LA): $1,200–$3,500
- ADU permit (LADBS): $3,000–$8,000
- Room addition (City of LA): $4,000–$12,000
- New construction (City of LA): $10,000–$30,000+
- Santa Monica and Pasadena: Generally 20–40% higher than LADBS fees
What Happens If You Build Without a Permit?
Unpermitted work in Los Angeles carries serious consequences:
- Mandatory disclosure: Unpermitted work must be disclosed to buyers when selling — it depresses your home’s value
- Demolition orders: The city can order unpermitted structures demolished at your expense
- Insurance voidance: Homeowner’s insurance typically won’t cover damage related to unpermitted work
- Retroactive permits: Getting a permit after the fact (“as-built” permits) requires opening walls, demonstrating compliance, and paying double fees — often more expensive and disruptive than doing it right the first time
- Fines: LADBS can issue fines for work performed without required permits
APLA never performs work that requires a permit without pulling one. It’s not just the law — it protects you.
Frequently Asked Questions — LA Building Permits
Can I pull my own permit in Los Angeles as a homeowner?
Yes. California law allows homeowners to pull permits for work on their own primary residence (owner-builder permit). However, if you sell within 1 year of completing permitted work as an owner-builder, you must disclose this to the buyer. For most homeowners, having a licensed contractor pull the permit is simpler and provides more legal protection.
How do I check if my property has unpermitted work in Los Angeles?
You can search LADBS’s online permit records at epermits.ladbs.org using your address. For independent cities, each has its own online permit portal. An unpermitted room, garage conversion, or addition will not appear in the permit records. A pre-purchase inspection by a licensed inspector can also identify unpermitted work.
Does APLA handle permits for projects in all LA cities?
Yes. APLA manages permit submissions to LADBS, Pasadena, Glendale, Burbank, Santa Monica, Culver City, Torrance, Manhattan Beach, Redondo Beach, Long Beach, and all other cities in our service area. We know each department’s specific requirements and submission formats.
How long does it take to get a building permit in Los Angeles in 2026?
For ADUs: 45–70 days at LADBS (state-mandated 60-day target). Kitchen and bathroom remodels: 3–6 weeks at LADBS. Room additions and structural work: 5–10 weeks. Independent cities vary — Culver City tends to be faster, Santa Monica and Pasadena may run longer for complex projects.
