Cost and timing
All panel upgrade jobs in San Francisco: $2,000 to $10,000
Half of 11,145 city permits list an amount in this range. Permit amounts are often lower than what you pay.
- Panel upgrades in San Francisco: $2,000 to $10,000 (6,396 permits)
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 timeline
Across San Francisco, a panel upgrade permit stays open about 77 days, from permit to final inspection
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. The permit itself is usually issued the same day. How long panel upgrade jobs take.
