This is the city’s permit record, not a license check. It does not show whether the state license is active, bonded or insured. How to read these records
Permits filed each year
How long permits take
Each point is the quarter the permits were filed, for stairs across San Francisco. A median counts only permits that have finished, so the shaded recent quarters look faster than they will end up: their slow permits have not finished yet. Hover a point for the slowest 10%. Gaps mean fewer than 5 permits. A rise in the issue line is the city’s review backlog, not the contractor. Too few of this contractor’s permits have finished to plot them.
Stairs permits
4 stairs permits: 2 completed, 2 in progress. Typically 13 days from filing to permit and 264 days from permit to final inspection.
