What a bathroom job costs
Half of the 3,299 bathroom permits declared between $40k and $125k (median $68k).
Declared permit valuation, not total project cost
Bay Area permits from the last 24 months to Oct 18, 2026. The value is what the applicant wrote on the permit, so it is not what a homeowner paid in total. Not every permit lists a value, so we take each contractor's median value and weight it by its permit count; it covers 3,299 permits from 813 contractors. Source: DataSF, San José open data. For an estimate by size and finish, use the home construction cost calculator.
B or B-2: which license fits your job
Both classes can act as your prime contractor. A B-2 is limited to remodels of an existing wood-frame house. If your plan changes the structure, look for a B.
| Job | B General Building | B-2 Residential Remodeling |
|---|---|---|
| Kitchen or bath remodel in an existing house | Yes | Yes, when the contract covers 3 or more unrelated trades |
| Addition or new rooms | Yes | No |
| Moving or removing a load-bearing wall | Yes | No |
| New home | Yes | No |
| Commercial or tenant work | Yes | No |

California rules for your contract
A down payment on a home improvement contract can't be more than $1,000 or 10% of the price, whichever is less. No progress payment can be more than the work done or materials delivered.
Source: California B&P Code 7159.5, checked Oct 18, 2026
Work under $1,000 in total (labor and materials) that needs no building permit doesn't require a license. The exemption doesn't apply if the person advertises as a contractor, has employees, or splits a job to stay under the limit.
Source: California B&P Code 7048, checked Oct 18, 2026
Every licensed contractor must keep a $25,000 contractor's bond on file with CSLB. That has been the amount since January 1, 2023.
Source: CSLB, bond requirements, checked Oct 18, 2026
A contractor with employees must carry workers' comp. Until 2028, a B contractor with no employees can legally file an exemption, so check which one yours did. From January 1, 2028, a workers' comp certificate is required for every license.

How this list is built
San Francisco permits come from DataSF, matched by license number. San Jose permits come from the city's open data, matched by business name. A contractor is listed only with evidence for bathroom work: a permit record whose description matches, or a source the contractor gave us.
License class, status, dates, bond and workers' comp come from CSLB's public data files: Master file Oct 16, 2026, workers' comp file Oct 17, 2026, processed Oct 18, 2026. Each card links to that license's live CSLB record. Full method.
