All panel upgrade jobs in San Francisco: $2,000 to $10,000

- 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 value (not a price)
Their typical permit lists $4,000 (half list more, half less)
That is the figure written on the permit form, which can be far from what you pay. Over their last 12 months (91 permits) it was $5,000. Kitchen jobs alone: typical permit $6,000 (41 permits). What panel upgrade jobs cost in San Francisco.
