Los Angeles Building Permits — Cost, Timeline & Process

Last updated: Verified:

The Los Angeles Department of Building and Safety (LADBS) issues building, electrical, plumbing, mechanical, and grading permits for construction inside the City of Los Angeles. The current Los Angeles code cycle became effective January 1, 2026: the Los Angeles Building Code and Residential Code adopt the 2025 California Building Code and 2025 California Residential Code with local amendments.

This guide explains the basics in plain English. Always verify specifics with LADBS before submitting an application, because fees and procedures change.

When You Need a Permit

You generally need a permit from LADBS for:

  • New construction, additions, and accessory structures (including ADUs and JADUs)
  • Structural alterations, load-bearing wall changes, and foundation work
  • Electrical, plumbing, mechanical (HVAC), and gas line changes
  • Roofing replacement (tear-offs) and new window or door openings in exterior walls
  • Swimming pools, spas, and retaining walls above a height threshold
  • Demolitions and grading work
  • Sign installations and certain site work

Minor cosmetic work — interior painting, floor coverings, cabinet replacement without plumbing or electrical changes, and similar repairs — is typically exempt. Check with LADBS if you are not sure, because the list of exemptions is narrower than many homeowners expect.

Permit Costs

LADBS fees have several components. Rather than a single flat number, expect a stack of charges:

  • Building permit fee — calculated from the project's declared valuation (construction cost). The fee rises on a published schedule as valuation increases.
  • Plan check fee — assessed when plans require LADBS review; the amount depends on the applicable fee schedule and project scope.
  • Separate MEP permit fees — electrical, plumbing, and mechanical (HVAC) work each generate their own permit and inspection fees.
  • Development impact fees — for new construction or added habitable area these may include school fees, park fees, sewer facility charges, and similar fees collected on behalf of other agencies.
  • Issuance and processing fees — small flat fees added at issuance.

For the exact dollar amounts for your project, use the LADBS Permit Fee Calculator on dbs.lacity.gov or contact LADBS directly. Fees are updated periodically, so quotes from older projects are not reliable. Certain ADUs under 750 square feet are exempt from most development impact fees under California state law.

Review Timing

LADBS does not publish one citywide permit turnaround time. The review path depends on the project:

  • Express Permits are for qualifying simple work that does not require plan check and can be obtained online through PermitLA.
  • Counter Plan Check is available for qualifying simple projects that do require plan review; LADBS states that these plans are reviewed the same day as submittal.
  • Expanded Counter Plan Check is used for certain modest projects; LADBS states that plans are assigned within a few days of submittal.
  • Regular Plan Check is used for larger or more complex projects; LADBS says plans are returned within weeks depending on workload.
  • ADU applications are subject to California's statutory ministerial review rules, including the 60-day action period for a completed application in the circumstances covered by state law.

Do not use a fixed 4–8 week or 3–6 month estimate as a guaranteed Los Angeles permit timeline. Corrections, clearances from other agencies, project complexity, and the selected plan-check path can materially change the schedule.

The Process

  1. Zoning check — Look up your property on ZIMAS to confirm zoning, overlay districts, and specific-plan constraints before designing.
  2. Prepare plans — Drawings must comply with the current Los Angeles Building Code and other applicable 2025 California code provisions as locally amended. Whether plans must be signed and stamped by a California architect or professional engineer depends on the project. LADBS policy provides exemptions for qualifying conventional light-frame construction and other work allowed by state law and the Los Angeles codes.
  3. Create an Angeleno account — Required to use ePlanLA, LADBS's online plan check and permit system.
  4. Submit the application — Express Permits go through PermitLA (no plan review). Anything that needs plan check goes through ePlanLA, where you upload drawings and pay initial fees.
  5. Plan check — LADBS reviewers check for building, residential, electrical, plumbing, mechanical, energy, green, and disabled-access code compliance. Other agencies (Planning, Fire, Public Works, Urban Forestry) may review in parallel.
  6. Corrections — Address comments in a resubmittal. Multiple cycles are normal.
  7. Permit issuance — Once plans are approved, pay the remaining fees and pull the permit. Work can now begin.
  8. Inspections — Schedule each required inspection through the LADBS online portal, LADBS Go app, or by phone.
  9. Final inspection — Pass the final inspection. For new dwellings, this leads to a Certificate of Occupancy.

Inspections

LADBS conducts construction-related inspections for residential and commercial buildings. Typical inspection stages for a residential project include:

  • Setbacks / site layout
  • Excavation and foundation (forms, steel, holdowns)
  • Underground plumbing and electrical
  • Rough framing
  • Rough plumbing, electrical, and mechanical
  • Insulation
  • Drywall nailing
  • Lath and exterior finish (if applicable)
  • Final building, plumbing, electrical, and mechanical

Each stage must be signed off before the next phase of work can proceed. LADBS offers online scheduling and, for qualifying cases, virtual inspections. Always keep the job card and approved plans on site during inspections.

Common Reasons for Denial or Correction

  • Plans do not meet the current Los Angeles Building Code or applicable California Title 24 requirements
  • Missing structural calculations or engineer's wet stamp
  • Zoning conflicts (setbacks, height, lot coverage, FAR, Baseline Mansionization)
  • Hillside Ordinance issues for properties in designated hillside areas
  • Very High Fire Hazard Severity Zone (VHFHSZ) defensible-space or materials requirements not addressed
  • Historic Preservation Overlay Zone (HPOZ) or Coastal Zone review not completed
  • Missing clearances from DWP, Sanitation, or Public Works
  • Incomplete disabled-access (ADA / CBC Chapter 11) compliance for commercial work

FAQ

How much does a building permit cost in Los Angeles?
LADBS fees are project-specific and depend on valuation, scope, work type, and whether plan check is required. Use the current LADBS Permit Fee Calculator rather than a fixed per-square-foot estimate.
How long does the building permit process take in Los Angeles?
There is no single LADBS turnaround time. Qualifying Counter Plan Check projects are reviewed the same day, Expanded Counter Plan Check projects are assigned within a few days, and Regular Plan Check is returned within weeks depending on workload. Corrections and outside-agency clearances can extend the process.
What work requires a building permit in Los Angeles?
Most structural work, additions, new construction, demolitions, grading, swimming pools, retaining walls, electrical, plumbing, and mechanical (HVAC) changes require a permit from LADBS. Minor cosmetic work — painting, floor coverings, cabinet replacement without plumbing or electrical changes — is generally exempt. When in doubt, contact LADBS before starting work.
Can I apply for a Los Angeles building permit online?
Yes. LADBS operates two online systems: PermitLA for Express Permits (no plan review required) and ePlanLA for projects that require a plan check. You must first create an Angeleno account to access ePlanLA. Some services are also available through the LADBS Go mobile app.
What happens if I build without a permit in Los Angeles?
Unpermitted work can trigger a code enforcement case and an Order to Comply from LADBS, require retroactive permitting with investigation fees, and must be disclosed when you sell the property. In severe cases the city can require removal of the work. Always verify permit requirements with LADBS before starting construction.
