## Which authority and approval steps control the project?

The notes below give architects and building designers a **high-level orientation** to permitting in the City of Los Angeles. Fees, forms, plan-check timelines, and submittal requirements are set and updated by LADBS — the **[official LADBS site (ladbs.org)](https://www.ladbs.org)** is always the authoritative source for a specific project.

## The authority: LADBS

The **Los Angeles Department of Building and Safety (LADBS)** is the AHJ for the City of Los Angeles. It performs plan check, issues building and combination permits, and conducts field inspections. Confirm your site is inside the City of Los Angeles — unincorporated LA County and neighboring cities (Long Beach, Pasadena, Santa Monica, and others) each have their own building department.

## Typical steps

| Step | What to expect |
| --- | --- |
| 1. Zoning / planning check | Confirm zoning, entitlements, and any Planning conditions before building permit |
| 2. Prepare the set | Drawings and calcs per California/LA codes and Title 24 energy compliance |
| 3. Plan check submittal | Submit for plan check; intake confirms the set is complete |
| 4. Corrections | Address plan-check comments and resubmit |
| 5. Permit issuance | Approved plans and paid fees produce the permit |
| 6. Inspections & CO | Staged inspections through construction, then certificate of occupancy |

## Codes and energy

Los Angeles enforces the **Los Angeles Building Code (LABC)** and **Municipal Code (LAMC)**, which adopt and amend the **California Building Standards Code (Title 24)** — including the California Building Code and Title 24 energy standards. Local seismic, grading, and zoning amendments apply on top, so work from the current LADBS-published editions.

## Bring a clean set to plan check

The process is the same shape everywhere — LA just has its own codes, agencies, and portal. Prepare and coordinate the full set in Harth, walk the [submittal checklist](https://harth.build/resources/permits/building-permit-submittal-checklist.md), review [typical review timelines](https://harth.build/resources/permits/how-long-does-plan-review-take.md), and see the general [permit process](https://harth.build/resources/permits/building-permit-process-explained.md). Then confirm the specifics — always — at ladbs.org.

## Frequently asked questions

### Who issues building permits in Los Angeles?

The Los Angeles Department of Building and Safety (LADBS) is the AHJ for the City of Los Angeles. It runs plan check, issues building and combination permits, and conducts inspections. Projects in unincorporated LA County or in other cities within the region (for example Long Beach or Pasadena) are handled by a different building department, so confirm which jurisdiction your site falls in.

### What codes apply to a Los Angeles project?

Los Angeles enforces the Los Angeles Building Code (LABC) and Los Angeles Municipal Code (LAMC), which adopt and amend the California Building Standards Code (Title 24), including the California Building Code and the Title 24 energy standards. Local amendments — seismic, grading, and zoning among them — matter, so rely on the current LADBS-published editions rather than the base California code alone.

### Is there an express or online permit option in LA?

LADBS offers online services and, for eligible minor scopes, express or over-the-counter paths, alongside standard plan check for larger projects. Eligibility, current processing options, and fees change, so check the live LADBS site for the applicable path for your project type.
