Hartford, CT Building Setbacks & Zoning: Setback Rules (2026)

The House A Building Type is Hartford's large, wide residential building on an oversized lot, set back from the front and corner side lot lines so the yard can stay landscaped. Section 4.14.2 of the Zoning Regulations sets its siting numbers for three districts: MX-1, MX-2 and N-1. The table was last amended on 12-13-2022.

In MX-1 the front build-to zone runs within 10 feet of the Building Line, and in MX-2 it runs within 20 feet. A build-to zone is a placement band, not a minimum: the building must reach toward the street rather than hang back. Under 4.18.1, at least 80 percent of each building must sit inside the build-to zone, and the remaining 20 percent must sit inside it or within 6 feet behind it. In N-1 there is no build-to band at all; the table says the Building Line is the minimum setback line, so the building can sit on that line or farther back.

Corner lots get a second band. The corner build-to zone is within 5 feet of the Building Line in MX-1 and within 15 feet in MX-2, and N-1 again treats the Building Line as the minimum setback. Corner occupation is required in MX-1 and MX-2, which means a principal building must be located at the intersection of the front and corner build-to zones.

The fixed setbacks are 10 feet at the side in MX-1, 15 feet in MX-2 and 10 feet in N-1. Rear setbacks are 15 feet in MX-1, 20 feet in MX-2 and 30 feet in N-1. Awnings, bays, eaves and cornices may project into a side setback up to 2 feet from the lot line, and porches or stoops may project into the front yard by at least 5 and no more than 10 feet, or to the established veranda line, whichever is more restrictive.

Coverage limits sit alongside the setbacks. MX-1 and MX-2 allow 35 percent building coverage, 70 percent maximum impervious area and 15 percent additional semi-pervious area. N-1 allows 30 percent, 40 percent and 10 percent. Note 2 adds that impervious and semi-pervious area in any front yard is capped at 25 percent. Parking is kept to the rear yard, with limited side yard parking in MX-1 and MX-2 for lots wider than 150 feet.
