Building Setbacks & Zoning in Stamford, CT

If you live in Stamford or are thinking about moving there, building setbacks & zoning are one of those things you probably won't think about until they affect you directly. Stamford has 3 specific rules on the books covering different aspects of building setbacks & zoning, and some of them might surprise you.

Setback Rules

In Stamford's R-6 Single- and Two-Family District, single-family homes need a 15-foot front yard (or 40 feet from the street centerline), a 35-foot rear yard, and side yards of 6 feet on one side and 10 feet on the other, 16 feet combined.

Key details: Front yard (single-family): 15 ft from street line. Rear yard: 35 feet. Side yards: 6 ft + 10 ft, 16 ft combined. District: R-6 Single- and Two-Family. Reduced side yard option: 6/12 ft with driveway easement.

Building within the required yard without approval violates the Zoning Regulations; the Zoning Enforcement Officer can order the encroachment removed or corrected, with penalties under City Charter § 248 and Connecticut General Statutes.

Structure Height Limits

Stamford's R-6 Single- and Two-Family District caps houses at two and a half stories or 30 feet, whichever comes first; non-residential uses allowed in the same district can reach three stories or 35 feet.

Key details: Max height (single/two-family): 2½ stories or 30 ft, lesser. Max height (non-residential): 3 stories or 35 feet. District: R-6 Single- and Two-Family. Governing instrument: Stamford Zoning Regulations § 5.Z.4. Current through: May 31, 2026 amendments.

A Building or Structure that exceeds the height limit cannot get a Zoning Permit or Certificate of Zoning Compliance; the Zoning Enforcement Officer can order the violation remedied, with penalties under City Charter § 248 and Connecticut General Statutes.

Lot Coverage Limits

In Stamford's R-6 Single- and Two-Family District, total lot coverage, including every building, driveway, walkway and hardscaped surface, cannot exceed 55% of the lot for a Single-Family Dwelling, 65% for a Two-Family Dwelling, or 75% for a permitted non-residential use. The cap sits in Zoning Regulations § 5.Z.4(f), current through the May 31, 2026 amendments, and is enforced by the Zoning Enforcement Officer.

Key details: Single-family cap: 55% lot coverage. Two-family cap: 65% lot coverage. Non-residential cap: 75% lot coverage. Counted surfaces: driveways, hardscape, artificial turf all count. Enforced by: Zoning Enforcement Officer, § 1.C.1.

Under § 1.C.2, the Zoning Enforcement Officer may institute action to restrain, correct or abate a lot-coverage violation, prevent occupancy of the building or land, and prevent any illegal construction or use connected with it. Penalties for exceeding the coverage limit or violating a related permit condition are set "as provided by General Statutes and City Charter section 248," so the Regulations route enforcement to those two sources rather than fixing a Regulations-set fine themselves.

The Bottom Line

Stamford's building setbacks & zoning rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Stamford is broadly strict or permissive.
