Sign Permit: Los Angeles restaurant guide

LADBS

What it is

New or altered business signs need an LADBS permit; LADBS inspects sign construction and enforces the sign code, and illuminated signs also need electrical sign-off.

When a restaurant needs it

New, replaced or altered exterior signs (illuminated or not).

How to apply

A licensed sign contractor files plans with LADBS (plan check or express permit); signs in specific plans, sign districts or HPOZs need Planning clearance first.

Documents you’ll need

Sign elevation drawing with dimensions
Site plan showing building frontage
Structural/attachment details
Electrical details for illuminated signs
Planning/HPOZ clearance if applicable

Fee

Varies — see LADBS Permit Fee Calculator

Processing time

Days to a few weeks

Renewal

None

Who files

Usually pulled by a CSLB-licensed sign contractor (C-45).

Good to know

Check ZIMAS for a sign district or specific plan before ordering a sign — many corridors restrict size, lighting and placement.
