San Jose

Every price on this page comes from a building permit filed with the City of San Jose. We pull the records directly from data.sanjoseca.gov, classify each permit by trade, and compute the typical cost for the metro. No surveys. No contractor self-reporting. No national averages.

San Jose is on our monthly refresh cadence. On the first of each month we ingest new permits filed during the prior month. The "Updated" date in the hero shows the last successful run.

This page covers the City of San Jose itself plus the broader San Jose metro where we have permit coverage. Suburban municipalities are added as their cities publish permit records. If you need a specific suburb, use the price alert sign-up below and we will notify you when it goes live.

Both. The valuation declared on a building permit is the contracted project cost the homeowner agreed to pay the contractor. It is the closest public record we have to the real out-of-pocket price for a project of that size in that city.

Use the typical cost as your negotiation anchor, not the final answer. Quotes vary with project scope, equipment quality, permits, labor market, and emergency timing. If your quote is more than double the typical cost shown here, ask for an itemized breakdown and a second opinion.
