Firms split into thirds by the usual value of the homes they work on, with each third's usual filed value weighted by permits. Home values: San Francisco Assessor-Recorder 2025 assessed values (Proposition 13 values, which usually sit well below market value). Under Proposition 13 a home assessed at its 1980s purchase price can carry a value far below what it would sell for today, so treat the home-value matching and the price-versus-similar-jobs comparison as rough.
| Firms working on | Usual home value | Usual filed value | Firms | Permits |
|---|---|---|---|---|
| Lower third | under $766,100 | $25,000 | 333 | 491 |
| Middle third | $766,100–$1,635,046 | $25,000 | 333 | 643 |
