Los Angeles — Permits & Forms

Last reviewed: July 6, 2026

Overview

In the City of Los Angeles, building permits are administered by the Los Angeles Department of Building and Safety (LADBS) under the Los Angeles Building Code (LAMC Chapter IX) and the adopted California Building Standards Code. Most simple scopes can be issued online as Express Permits through PermitLA, while anything that needs plans goes through ePlanLA for plan check. Core application forms (e.g., the Application for Building Permit or Grading & Certificate of Occupancy) and trade-permit forms are standardized citywide.

The most important timing rule: an application is deemed abandoned if inactive for 180 days and an issued permit generally expires if work doesn’t start within 12 months; extensions require written justification (see § 105.3.2 and § 105.5.1).

Permit Pathways (LADBS)

• Express permits (no plan check)
  • Use the online portal for small-scope work that does not require plan review. LADBS issues these via PermitLA (Express Permits). Eligibility is determined by the portal’s checklist and intake logic. Verify scope eligibility in the portal.
• Plan-check permits (plans required)
  • Submittals are made electronically through ePlanLA. LADBS routes plans for interdepartmental clearances (e.g., Fire, Sanitation/LID, Public Works/BOE) as needed.

LADBS acts on permit applications “within a reasonable time” at plan check intake; the codes do not fix a specific number of days for first review.

Official LADBS Forms and Portals (What you’ll actually file)

• Core building application
  • Application for Building Permit or Grading & Certificate of Occupancy (PC/STR/App.01) — used for most buildings, grading, and C/O workflows.
• Trade permits (often separate from the building permit)
  • Electrical Permit Application (PC/ELEC/App.02) — required for electrical scopes.
  • Plumbing Permit or Plan Check (PC/MECH/App.05) — required for plumbing/mechanical scopes.
  • Fire Sprinkler Permit or Plan Check (PC/MECH/App.03) — when fire protection work is proposed.
• Owner-builder
  • Notice to Property Owner for Owner-Builder Permits — acknowledgement required when permits are pulled as owner-builder.
• Digital submittal and express issuance
  • ePlanLA (Electronic Plan Review) — upload plans, respond to corrections, and track reviews.
  • PermitLA (Express Permits) — online intake and issuance for eligible, no-plan-check work.

Related entitlements or clearances may also require forms from other departments:

• Los Angeles Fire Department (LAFD) — Fire/Life Safety Plan Review and LAFD Plan Check Application.
• LA Sanitation & Environment (LASAN) — LID WebUI for Low Impact Development submittals.
• Public Works/BOE — BOE Public Permits Portal and Class “A” Permits for work in the public right-of-way.

What the Code Says About Timing, Validity, and Fees

• Application intake and review
  • LADBS examines permit applications and amendments “within a reasonable time” before approval or written rejection. See § 105.3.1.
  • Applications are abandoned after 180 days of inactivity unless extended for just cause in writing; see § 105.3.2.
• Permit validity and expiration
  • Issued permits generally expire if work does not commence within 12 months, or if work is suspended/abandoned for 12 months after start; extensions require a written request and cause; see § 105.5.1.
  • The permit must be kept on-site until project completion; see § 105.7.
• Plan-check fees and logistics (LAMC)
  • No fee is charged to verify required corrections from LADBS or other departments; however, revisions unrelated to corrections can trigger supplemental plan-check fees; see § 91.107.3.1.8.
  • LADBS may collect specific preinspection fees for hillside grading, signs, demolition, or where the Department determines a preinspection is necessary; see § 91.107.3.2.
  • Off-hour plan check is available upon request (paid under § 98.0422 as referenced in § 91.107.3.3).
  • Paper plan logistics still appear in the code (e.g., number of sets), but LADBS accepts digital plans via ePlanLA; if submitting paper, the number of plan sets is “one more than the number of permit applications”; see § 91.107.3.1.7.3. Verify with LADBS for current practice.

Cross-checks before you file

• Confirm your project is allowed by base zoning and any overlays; start with the Los Angeles Zoning Code (Chapter 1) and Chapter 1A, and see the Los Angeles zoning & planning overview.
• Ensure your proposal meets Los Angeles Development Standards and any required Los Angeles Parking.
• If in a design-controlled area, check Los Angeles Design Review and Los Angeles Overlay Districts; historic properties may trigger Los Angeles Historic Preservation.
• For new or modified signage, see Los Angeles Signage.
• For accessory units, use Los Angeles ADUs and the state-adopted California Building Standards Code as the governing construction code baseline.

Permit Timing & Fees — Key Rules (Decision Table)

Plan Check Routing and Clearances (Typical)

• Fire/life safety: LAFD plan review is often required for larger commercial/industrial scopes before LADBS approval.
• Stormwater/LID: Many projects must submit LID plans through LASAN’s LID WebUI.
• Public right-of-way: BOE may require A‑Permits/B‑Permits or other clearances when modifying driveways, sidewalks, or utilities.

These clearances commonly appear in LADBS submittal scenarios (e.g., multifamily new construction, tenant improvements) and are handled in parallel with ePlanLA reviews. Verify with the jurisdiction for your project’s exact routing.

Checklist

• Confirm your zoning, overlays, and any design/historic triggers using the Los Angeles Zoning resources; obtain planning entitlements if needed.
• Decide your LADBS path: Express Permit via PermitLA (no plans) or ePlanLA plan check (plans required).
• Prepare and submit the correct LADBS forms:
  • Application for Building Permit or Grading & C/O (PC/STR/App.01) for building/grading.
  • Separate trade applications for electrical, plumbing/mechanical, and fire sprinklers, as applicable.
  • If applying as owner-builder, include the Owner-Builder Notice.
• Upload plans to ePlanLA and respond to correction cycles; keep the permit active and avoid 180‑day application lapses.
• Anticipate preinspection fees if in hillside grading areas, for signs, or for demolition.
• Coordinate required clearances (LAFD, LASAN/LID, BOE) early to reduce plan-check delays.
• Post the issued permit on site and request inspections; mind the 12‑month expiration clock and request extensions in writing if needed.

Risks & Ambiguities

Plain-English Summary

In Los Angeles, small jobs can be permitted online with PermitLA, while anything needing plans runs through ePlanLA and LADBS plan check. Keep your application active, respond to corrections promptly, and remember the 180‑day application and 12‑month permit clocks; if you need more time, request an extension in writing. Some projects also need Fire, Sanitation/LID, or Public Works approvals before LADBS can issue your permit.
