Cost and timing

All retrofit jobs in Los Angeles: $20,000 to $60,000

Half of 1,205 city permits list an amount in this range. Permit amounts are often lower than what you pay.

How to read this range

Contractors write a job value on the permit form, and the city uses it to set the permit fee. It is not the contract price, and it is often lower than what you pay. A quarter of the permits list less than this range, and a quarter list more. Use it to see if a quote is in the normal range.

Permit value (not a price)

Their typical permit lists $6,750 (half list more, half less)

That is the figure written on the permit form, which can be far from what you pay. What retrofit jobs cost in Los Angeles.

Permit timeline

This is not how long the crew works at your home: most of it is waiting for the inspection. Ask them how many days the work takes. Waiting for the permit adds about about 4 months. How long retrofit jobs take.
