New Haven County's housing: older cities, newer small towns

New Haven County holds 371,959 housing units across 27 towns, and taken together they lean older than the state. By the Census Bureau's 2019-2023 estimates, 70 percent of those units were built before 1980, against 67.7 percent for Connecticut, and 22.8 percent predate 1940, against 20.4 percent. Only 9.4 percent went up in 2000 or later, where the statewide share is 11.8 percent. Owners occupy 62 percent of the county's occupied homes, below the state's 66.2 percent, and single-family detached houses make up 54.2 percent of units, compared with 58.7 percent.

Much of that age sits in the cities. Three towns have a median year built before 1960: New Haven at 1952, Ansonia at 1954 and Waterbury at 1959, which makes the typical home in each about 74, 72 and 67 years old. New Haven is also the largest town, with 59,626 units, and it has both the county's highest prewar share, 40.8 percent, and its lowest owner share, 28.4 percent. Waterbury's owner share is 45 percent. In Meriden, 26.7 percent of units were built before 1940 and owners occupy 59.9 percent of homes. Where most homes are rented, the roof decision likely rests with a landlord rather than with the household living under it.

Two rules follow that age up the ladder. Housing built before 1978 is, with some exceptions, target housing under EPA's Renovation, Repair and Painting rule, and the 70 percent of the county's units built before 1980 include its pre-1978 housing. The rule reaches paid work that disturbs painted surfaces, which on a re-roof can mean fascia, rake boards or trim. Exterior jobs that disturb 20 square feet or less of paint fall under a minor-repair exclusion, though window replacement and demolition of painted surfaces do not. Separately, IRC R908.5 requires flashings, edgings, outlets and vents that are rusted, damaged or deteriorated to be replaced rather than reused, and on a prewar city house that metal deserves as close a look as the shingles.

The newest housing is in some of the smaller towns. Oxford is the only town with a median year built of 1980 or later: its median is 1986, putting the typical home at about 40 years old, and 33.6 percent of its units date from 2000 or later. Beacon Falls at 31.6 percent and Middlebury at 29.4 percent are close behind. Many of those houses are likely still under their first roof. InterNACHI gives 3-tab asphalt about 20 years and architectural about 30, and notes that weather, design, material quality and upkeep all move those figures, so roofs from the early 2000s are reaching the age where replacement comes up.

Connecticut's counties are no longer Census reporting areas, so no county-wide median year is given. Town estimates carry a margin of error, which is wider in smaller towns.
