Where Tampa's Dryer-Vent Fire Risk Concentrates
The single-family suburbs
Dryer-vent fire risk in Tampa Bay concentrates where homes are single-family — and the suburbs lead. In Riverview and Wesley Chapel, about 80% of homes are single-family houses, well above the metro-wide 62%; denser communities like Brandon carry a far larger share of multi-unit buildings (about 36%). That housing form is the risk axis, not a home's age: a single-family house has its own private dryer vent — often a long, bend-filled run (residential code allows a dryer exhaust duct up to 35 feet, reduced for every elbow) where lint collects far more than in the typically shorter vent runs of multi-unit buildings. And failure to clean is the leading cause of dryer fires — about a third (33%) of them. The more single-family the neighborhood, the more private vent runs there are to keep clear.

Methodology
This is a housing-stock risk profile, not a count of local fires. We compiled U.S. Census American Community Survey (2022 5-Year) housing data — units in structure, year built, and total units — for four Tampa-area communities (Brandon, Riverview, Wesley Chapel, Carrollwood) and read it against two sourced facts about dryer-fire risk: that failure to clean is the leading cause of dryer fires (NFPA), and that residential code caps a dryer exhaust duct at 35 feet (2021 IRC). The neighborhood-level connections we draw — more single-family homes means more private, longer vent runs to maintain — are reasoned inferences from that housing mix, not national research findings, and we do not claim any neighborhood's actual dryer-fire counts. One thing we deliberately do not assert: a home's age, on its own, is not treated here as a dryer-vent risk factor — public housing-age data can't establish that, so we make no age-based risk claim.
