By home value

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: Marin County assessed land and improvement values from MarinMap parcels (Proposition 13 values, which usually sit well below market value). Under Proposition 13 a home bought decades ago 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.

Marin County files the fewest windows & doors permits in January (79 against an average month of 100) and the most in July (145). If you can choose, ask for quotes in a quiet month.

How these numbers are made

Source: Marin County Community Development Agency building permits on homes in unincorporated Marin (the County's open-data permit and inspection files). The window is October 2023 through September 2026; a permit filed after that isn't here yet.

Usual is the middle permit: half were filed for less, half for more. Only permits with a filed value count; a value of $0 or none is left out.

The spread is approximate: we keep seven points of each firm's own range of filed values, not every permit, and pool them.

Common questions

  • How many quotes should I get for a windows & doors job in Marin County (unincorporated)?At least three. In the permit record the middle half of Marin County (unincorporated) windows & doors firms usually file between $10,000 and $16,200 a job, so two ordinary firms can sit 1.6 times apart and both be normal for Marin County (unincorporated). A third quote shows which one is the outlier. Filed values are what contractors wrote on permits, not quotes, so use them to judge the spread, not to price your own job.
  • What range is normal for windows & doors jobs in Marin County (unincorporated)?Half of permits were filed between $5,700 and $24,900; 8 in 10 between $2,700 and $50,000. These are approximate, pooled from each firm's own spread.
  • How much do window installers charge in Marin County?The usual windows & doors job is filed at $12,214; the middle half of firms usually file between $10,000 and $16,200. The 10 firms with the most permits in the last 12 months usually file $10,912, less than the usual. See every firm's usual job →
  • Why is this different from the per-window prices I see online?Online prices are quoted per window. A filed value is one number for the whole job on one permit, often many windows plus the work around them, and the Marin County file does not record how many each job covered, so we can't turn $12,214 into a price per window.
  • How much is the windows & doors permit fee in Marin County?Marin County's published base fee is Window/Door Replacement (non-structural): $493.91 (Marin County Permit Base Fees, read October 2026). These are base fees; the County adds impact fees and taxes, and other approval agencies can charge their own. The fee is separate from the contractor's price.
  • Do bigger houses get bigger bills?In the file, yes for the firms: those working on the upper third of homes by value usually file $16,200, the lower third $10,000. That is firms, not single jobs.
  • Where does this data come from?Marin County Community Development Agency building permits on homes in unincorporated Marin (the County's open-data permit and inspection files), read October 2026. How the records work in Marin County (unincorporated) →
