Do you need a permit for toilet installation in San Francisco, CA?
Usually no
A permit is usually not required for toilet installation on its own. San Francisco still applies zoning rules such as setbacks, lot coverage and HOA approval, and any structural, electrical or plumbing work added to the job does need a permit.
San Francisco sits in San Francisco County, California. Seismic bracing, energy-code (Title 24) compliance and coastal exposure all factor into permit scope and material selection. Work outside city limits is permitted by the county building department rather than the city.

Why is the installed price higher than the fixture price?
Labour includes removal, disposal, a new seal and supply, and levelling the fixture. Rotted flanges and damaged subfloor are the most common reasons a simple swap becomes a larger job.

1-3 hours of work. Permit review and inspection scheduling are usually the largest source of variation.
What changes the price the most?
The largest cost drivers are fixture price, from builder-grade two-piece to wall-hung or bidet models; flange repair, riser or subfloor damage found after removal; rough-in distance and whether the drain has to move.
