Half of San Jose's homes were built in 1976 or earlier, and 8.9% were built in 2010 or later. With only 8.9% of homes built since 2010, many San Jose homes are older; the USFA recommends replacing coiled-wire foil or plastic venting with rigid, non-ribbed metal duct.
In California, clothes dryers were the equipment involved in 5.9% of residential structure fires where the equipment was identified, in fire department records for 2020 to 2024, above the national 4.6%.

San Jose dryer vent code rules
San Jose's Building Division says that effective Jan. 1, 2026, the 2025 state building codes replaced the 2022 codes, and that the 2025 codes became applicable to all building permit applications made on or after January 1, 2026. The 2025 codes the city lists as adopted include the California Residential Code (CCR Title 24 Part 2.5) and the California Mechanical Code (Part 4).
In the San José Municipal Code text we read, the city's amendments to the California Residential Code are at Sections R301.2, R309 and R602.10, none of them the dryer exhaust rules, and for the California Mechanical Code the city does not adopt Sections 1.8.4, 1.8.5, 1.8.7, 1.8.8 and 1.8.9. The California Residential Code's own dryer exhaust section was not available for us to read, so this page gives no dryer duct length limits for San Jose.
Permits for dryer vent work in San Jose
San Jose's Development Services Permit Center says the installation or replacement of ducts, furnaces and other mechanical equipment requires a mechanical permit, and notes that insurance companies may deny claims related to unpermitted work; its mechanical projects page does not mention dryer vents. Among work for which a mechanical permit shall not be required, San José Municipal Code section 24.02.140 lists "Replacement of any component part of assembly of an appliance which does not alter its original approval and complies with other applicable requirements of the technical codes." The Permit Center is on the 1st Floor of San José City Hall, 200 E. Santa Clara St., and its phone line, 408-535-3555, is answered Monday to Friday, 7am to 4pm.

The Permit Center's smoke and carbon monoxide alarm page (updated 04/14/2026) says carbon monoxide alarms are required in dwelling units that have a fireplace, an attached garage with any kind of opening to the dwelling unit, or a fuel-fired appliance, and the fuel-fired appliances it names include the clothes dryer. Where any of those exist, the page says to place a carbon monoxide alarm outside each sleeping area in the immediate vicinity of the bedrooms and on every occupiable level of the dwelling unit, including basements.
Code Enforcement's Multiple Housing Inspection Program inspects multiple housing buildings on a rotational basis, with the frequency set by each building's tier: Tier 3 buildings on a 3-year cycle covering 50% of units, Tier 2 on a 5-year cycle covering 25% of units, and Tier 1 on a 6-year cycle with mandatory annual self-certifications, in which the city audits 10% of self-certified units. The program's tier page says any change to the structural, electrical, plumbing or mechanical configurations of any part of a building requires a permit and inspection, and that work without the required permits or final inspection approval can result in a lower tier assignment. It adds that the City of San José has required permits for building construction and improvements since 1928.
