What this page is

This page counts San Jose permits whose work description matches PermitBriefly's water heater filter. It is a market-activity page for Water Heater contractors and suppliers. It is not a list of available jobs, and it publishes no addresses or individual permit rows.

Permits by month

Records in this snapshot begin August 25, 2026, so August is a partial month, not a full month.

Month	Permits	Share
August 2026	62	7.8%
September 2026	307	38.6%
October 2026	352	44.2%
November 2026	75	9.4%

What the work descriptions show

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

Pattern in the city description	Records	Share
WH-R code: like-for-like replacement	627	78.8%
WH-HP code: heat-pump water heater	111	13.9%

Reported project value

San Jose reports a valuation above $0 on only 9 of these 796 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. San Jose's own window in this snapshot is August 25, 2026 to November 7, 2026; its records arrive as a rolling pull, accumulated weekly.
• 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.
