Half of San Antonio's homes were built in 1985 or earlier, and 15.1% were built in 2010 or later. With only 15.1% of homes built since 2010, most San Antonio dryers vent through older ductwork: check the hose behind yours, since the USFA recommends replacing coiled-wire foil or plastic venting with rigid, non-ribbed metal duct.

In Texas, clothes dryers were the equipment involved in 4.1% of residential structure fires where the equipment was identified, in fire department records for 2020 to 2024, below the national 4.6%.

San Antonio dryer vent code rules

San Antonio enforces the 2024 International Residential Code, adopted by Ordinance 2025-01-30-0075 and in effect since May 1, 2025, according to the city's Chapter 10 building-related codes.

San Antonio's local amendments delete the residential code's makeup-air section for dryers (M1502.6). For commercial buildings under the mechanical code, the city adds mechanical equipment to the list of things a dryer exhaust must end at least 3 feet away from (section 504.4.1).

Under the 2024 International Residential Code, a dryer exhaust duct can run at most 35 feet, minus an allowance for each elbow (M1502.4.6.1); the hose behind the dryer must be one listed piece of 8 feet or less (M1502.4.3); and the duct must end outside with a backdraft damper and no screen (M1502.3), and domestic booster fans are not allowed (M1502.4.5).

Permits for dryer vent work in San Antonio

A cleaning is maintenance; a new vent or a reroute is construction. In San Antonio, residential permits go through the city's Development Services Department (210-207-1111). Ask it whether a reroute or new vent needs a permit.

Renting or in a condo in San Antonio

Most San Antonio households own their home; 47.8% rent, and 30% of homes are in buildings with five or more units. A duct inside walls or up to the roof generally falls to the owner or the condo association, so check your lease or association documents before booking; see apartment, condo and commercial dryer vent cleaning.

HomeGuide's ranges at the top of this page are national; the cost guide breaks them down by floor, problem and company.
