How to read this
The Contractors State License Board lists complaints it has sent for legal action, citations it has issued, and warning letters. A complaint or accusation is an allegation, not a finding. A citation is the board's finding that a rule was broken; the contractor can appeal it. Complaints closed in the contractor's favor are never listed. Most contractors have no items.

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.

What to ask before you hire
About Matthew P Leffers
- The state lists a case on this license. A case is not a finding. Read it on the state's license page and ask the contractor about it.
- Ask who will do the work. Anyone they pay to work on your home must be covered by workers' comp.
- Ask what the warranty covers and for how long, in writing.
Worth asking any panel upgrade electrician
- Can you show me proof of liability insurance and your bond?
- What size panel, and does the utility need to change the service to my house?
- Who arranges the power shutoff with the utility?
- Who pulls the permit, and who meets the inspector?
