Re‑roof permits in Los Angeles: who issues them and what they check
Almost every re-roof in Los Angeles needs a permit, and which office issues it depends on where the house is. Here's how it works in the city, in the county's other cities and in unincorporated areas.
By Sadie Yancey, Roofing Guides Editor · Updated September 2026
Inside the City of Los Angeles, re-roof permits come from LADBS; in other cities they come from that city's building department, and in unincorporated areas from Los Angeles County. Published LADBS roofing permit figures run $250-$1,200, and inspectors check fire ratings, cool-roof rules and how the roof was installed.
Which office issues the permit
Los Angeles County has 88 incorporated cities, and each runs its own building department. A house in El Sereno, Highland Park or the San Fernando Valley is in the City of Los Angeles and goes through LADBS; a house in Alhambra or Burbank goes through that city; and a house in an unincorporated community such as Altadena goes through Los Angeles County Public Works.
Your roofer should know which applies before quoting.
What it costs
Published figures put LADBS roofing permits at $250-$1,200, with a standard residential re-roof around $370. Other cities set their own fees, usually based on the job's value or the roof area.
The permit is a small share of a re-roof, and skipping it can cost far more later.
What the inspector checks
Inspectors look at the roof assembly against the code: the fire rating required for the address, the cool-roof rule where it applies, underlayment and flashing, and how many layers are on the roof. Some re-roofs also need the deck inspected before the new covering goes on.
Cool-roof rules are covered in our Title 24 cool roof guide.
Layers and tear-offs
Codes limit how many layers of roofing a house can carry. A roof that already has two layers has to be torn off to the deck before a new one goes on, which also lets the deck be checked and repaired.
Even where an overlay is allowed, a tear-off is often the better job.

Fire zones and historic districts
Homes in Very High Fire Hazard Severity Zones need Class A assemblies and ember-resistant details, and homes in historic districts may need review before materials change. Our HPOZ guide covers the historic side.
Both are checked through the permit process, so they belong in the scope from day one.
Why the permit matters later
A closed permit is proof the roof was installed to code. Buyers, lenders, appraisers and insurers may ask when the roof was replaced and whether it passed inspection, and the permit answers that in one document.
An unpermitted roof can complicate a sale or an insurance claim.
Who pulls the permit
On most jobs the roofer pulls the permit and schedules the inspections as part of the work. Make sure the scope says so, and ask for a copy of the final sign-off for your records.
If a roofer suggests skipping the permit to save money, that's a reason to keep looking.
