Siding Contractors in New Haven County, Connecticut

Siding rules town by town

Sources: historic review from Preservation Connecticut's list, checked September 17, 2026 (“None adopted” means no district or property is listed); homes built 1979 or earlier from Census ACS 2020–2024 table B25034, via Census Reporter; ultimate design wind speed from 2022 Connecticut State Building Code Appendix AY; phones from the state list of municipal building officials (updates as of April 6, 2026).

Historic district review across New Haven County

Connecticut lets a town create a local historic district by vote of its legislative body (CGS 7-147a) or designate a single historic property by ordinance (CGS 7-147p). Inside either, no building may be altered until the commission approves a certificate of appropriateness for its exterior architectural features, meaning the parts open to view from a public street, way or place (CGS 7-147d, 7-147s). The town may not issue the building permit first, and the certificate is required whether or not a permit is. The commission must weigh “the type and texture of building materials” (CGS 7-147f). Ordinary maintenance or repair that does not change the appearance or design is exempt (CGS 7-147j).

Here that review reaches neighborhoods, not only town greens. New Haven's three districts are urban neighborhoods; Madison added the mostly residential Old Elm Street district along the Boston Post Road in 2025; Cheshire's South Brooksvale is a rural neighborhood. Wallingford's three designated properties are houses, and Prospect's is the David Hotchkiss House, built in 1820. Middlebury's selectmen reviewed a proposed historic properties commission on September 8, 2026 and took no action (Patch).

A National Register listing is different: the National Park Service says it “places no restrictions on what a non-federal owner may do with their property” unless federal funding or permits are involved, though local laws may apply; Hamden's zoning, for one, requires a Special Permit to modify a register-listed building. Local district boundaries can differ from National Register ones, so check a house near a line with the town's commission.

Housing age and the EPA lead rule

Summed across the 27 towns, the Census Bureau's 2020–2024 estimates count 373,260 housing units, 259,011 of them (69.4%) built in 1979 or earlier and 55.9% in 1969 or earlier; because the Census groups the 1970s, the pre-1978 share falls between the two. By town, the pre-1980 share runs from 38.1% in Oxford to 86.6% in Ansonia, with West Haven at 80.3% and New Haven at 77.6%.

The year that matters is 1978. The EPA Renovation, Repair and Painting rule (40 CFR 745) covers paid renovation that disturbs painted surfaces on most pre-1978 housing, siding included, unless certified testing finds those components free of lead-based paint. Its exclusion for 20 square feet or less of painted exterior never applies to demolition, which EPA defines as removing a painted component in a way that destroys or ruins it, so a tear-off of painted siding done that way is covered at any size. The firm must be EPA-certified, hand over EPA's Renovate Right pamphlet before work starts, and cover the ground with impermeable sheeting at least 10 feet beyond the work.

Wind and code requirements for new siding

The 2022 Connecticut State Building Code is the building code in every town (CGS 29-253). It is based on the 2021 International Residential Code (IRC), and Connecticut does not amend the IRC's wall-covering chapter. Its successor, expected July 1, 2026, is delayed pending legislative approval (state Department of Administrative Services, checked September 17, 2026). Its permit exemption for siding stops at repairs limited to 25 percent of the siding within one calendar year (amended R105.2).

Design wind speed: 120 or 125 mph

Appendix AY sets an ultimate design wind speed of 125 mph in Branford, East Haven, Guilford, Madison, New Haven, North Branford and West Haven and 120 mph in the other 20 towns, and it places all 27 in the hurricane-prone region. Siding, backing and fasteners must resist the wind loads in Tables R301.2.1(1) and R301.2.1(2) (R703.1.2). At 120 mph, Table R703.3.2 sets no height limit on standard attachment in Exposure B, a 30-foot maximum mean roof height in Exposure C, and requires a design in Exposure D. Appendix AY assigns no exposure category.

Vinyl, fiber cement and stone veneer

Vinyl must be labeled to ASTM D3679 and insulated vinyl to ASTM D7793, both installed to the manufacturer's instructions (R703.11, R703.13). Where foam plastic is the only sheathing, Table R703.11.2 sets minimum ratings for mean roof heights of 30 feet or less: with interior gypsum wallboard, -37.4, -52.4 and -62.1 psf in Exposures B, C and D at 120 mph. The table permits linear interpolation, which gives about -41.2, -57.6 and -68.3 psf at 125 mph. Fiber-cement lap siding must meet ASTM C1186 Type A, Grade II minimum (or ISO 8336 Category A, Class 2) and lap at least 1-1/4 inches (R703.10.2). On stud walls, adhered stone veneer must stay at least 4 inches above the earth (R703.12.1). Behind any siding, R703.2 requires a continuous water-resistive barrier, and R703.4 requires flashing at windows, doors and wall-roof intersections.

Common questions about siding in New Haven County

What Connecticut law requires of any siding contractor

Connecticut's Home Improvement Act treats siding work on a private residence priced over $200 as a home improvement (CGS 20-419), and the contractor must hold a certificate of registration from the Department of Consumer Protection (CGS 20-420, 20-420a) and may not start before the permit is obtained (CGS 20-427). The signed, written contract must show start and completion dates, the registration number and the right to cancel (CGS 20-429). The owner may cancel until midnight of the third business day; Sundays and legal holidays do not count, and since July 1, 2025, Saturdays do not either (CGS 42-134a, 42-135a).
