What the work descriptions show

The patterns below were built on San Jose's coded work descriptions and are applied to Cupertino's descriptions unchanged; one record can match several patterns. A pattern with no row here matched no Cupertino description, which can mean the same work is described in different words.

Reported project value

Cupertino reports a valuation above $0 on only 25 of these 26 permits, which is too few to print a median that means anything. No typical-value figure is published for this trade; the dashboard shows reported values record by record where they exist.

Methodology

• Source. Public building-permit records published by each city, collected by PermitBriefly in its Monday refresh. This page is built from the snapshot collected November 9, 2026. Cupertino's own window in this snapshot is August 4, 2026 to October 30, 2026; the city publishes monthly reports, so its records lag the rolling-pull cities by one cycle.
• Counting. Every figure counts unique permits: records are deduplicated on city and permit number before any total, share, or valuation is computed, so a record a city lists twice is counted once.
• Trade categories. Assigned by PermitBriefly's automated filter over each record's work description. They are not classifications supplied by the city, and roughly half of all records land in "Other / unclassified" because their descriptions do not name a tracked trade.
• Valuations. The value the applicant reported to the city, printed only where at least 30 records in the group report a value above $0. A reported valuation is not a quote, a contract price, or a guarantee of project size.
• Company counts. Records are grouped with the same name normalization PermitBriefly uses in its own tooling, then matched against a hand-verified list of company names. Recorded names that are individuals, or that could not be verified as a company, are never printed.
• What is never published. Street addresses, property owner names, APNs, and individual permit rows stay off these public pages. They are the working data behind the subscriber dashboard.
