Key Takeaways
- LADBS issues certain routine jobs, including re-roofs and same-size A/C replacement, as Express Permits without plan check.
- Replacing more than half of a roof in Los Angeles triggers the cool-roof requirement.
- Express Permits still require inspections and a final sign-off.
- Jobs outside the Express list go through plan check, which takes longer.
- California also has statewide rules for solar and ADUs that interact with LADBS permits.
Re-Roof Express Permits
Re-roofing with Class A or B coverings weighing under 6 lb/sq ft is an Express Permit. Class A roofing is required in Very High Fire Hazard Severity Zones. Replacing more than 50% of a roof triggers the cool-roof requirement for a rated product.

What "Express" Means in Los Angeles
LADBS Information Bulletin P/GI 2020-003 lists the work that can be issued as an Express Permit: the permit is issued without plan check because the scope is routine. You still apply, pay fees and pass inspections. The two most common home projects on the list are re-roofing and replacing an air-conditioning unit with one of the same size. Because there is no plan review, Express Permits are typically much faster than standard permits, though LADBS does not promise a fixed turnaround on the bulletin.
The Cool Roof Rule
The LADBS cool roof fact sheet explains that when more than 50% of a roof is replaced, the new roofing must meet cool-roof requirements, which set minimum solar reflectance and thermal emittance for the roofing product. Most roofing manufacturers rate their products, so ask your roofer to confirm the product meets the requirement and to list it on the permit. Repairs that replace less than half the roof are not caught by this rule.
Tip: keep the product data sheet with your permit records; it shows the roof met the cool-roof rule if a buyer asks later.
When You Need Plan Check Instead
Anything structural, any change in roof framing, a larger or relocated HVAC system, additions and ADUs fall outside the Express list and need plan check. California's statewide ADU laws, explained by the state housing department, limit how cities can restrict ADUs; see ADU Permit Requirements: What Homeowners Need to Know. For solar, see Solar Panel Permit Rules for Homeowners.
Questions to Ask a Los Angeles Contractor
- Is this job on the LADBS Express Permit list, or does it need plan check?
- If more than half the roof is being replaced, which cool-roof product will you use?
- Who will pull the permit and schedule inspections?
- Will you provide proof of the final inspection before final payment?

Checking a Los Angeles Permit Record
Los Angeles publishes issued building permits as open data. Search by address to confirm a permit was issued and finaled; How to Look Up Building Permits for a House explains how.
How to Apply for an LADBS Express Permit
- Confirm the job is on the Express list in Information Bulletin P/GI 2020-003.
- Gather details: address, scope, and for re-roofs the roofing product and whether more than half the roof is being replaced.
- Apply through LADBS (typically by the contractor) and pay the fees.
- Do the work and request inspections as the permit requires.
- Get the final and keep the permit and product information.
If LADBS determines the work is outside Express scope, it will be routed to plan check. Ask early to avoid surprises. For what to expect at each inspection, see Building Permit Inspections: What Inspectors Check and When.
Express Permits and Home Sales
Because Express Permits are recorded like any other permit, they show up in the city's permit history for the address. A re-roof or A/C replacement with a finaled Express Permit is easy for a buyer to verify, while the same work without one raises questions. That is one more reason to make sure your contractor pulls the permit and books the final.
Who Issues Permits in Los Angeles
Residential permits in Los Angeles are issued by the Los Angeles Department of Building and Safety (LADBS). Its website has the current application portal, fee schedule and inspection scheduling. Issued permits are published as open data in LADBS Building Permits Issued 2020–Present, which is the source of the permit counts and recent permits shown on our Los Angeles pages. Rules and fees change, so confirm with the department before you start work.
