Foundation work in Fairfield
With 50% of homes built before 1960, Fairfield has a lot of older foundations. Additions and garages here mean new footings next to old walls, dug carefully so we don't undermine what's already there.
Parts of Fairfield near Long Island Sound are in FEMA flood zones, where additions and rebuilds can require elevated foundations with flood vents. The town's floodplain manager decides, and we build to the approved plans.
The median home in Fairfield was built in 1960, close to the 1960s house that's typical statewide. That's newer than next-door Bridgeport (median 1954) and older than Westport (1968).

Concrete foundations in Fairfield: questions
Do I need a permit for a foundation in Fairfield?
Yes. New foundations, additions and garages need a building permit from Fairfield's building department, and most towns inspect footings before the pour. Deck and porch footings are usually part of the deck permit.
How deep are footings in Fairfield?
42 inches below grade, the same as everywhere in Connecticut. The state building code sets the frost depth statewide, and towns can't change it.
Do flood zone rules affect a foundation near the shore?
They can. In a FEMA flood zone, additions and substantial rebuilds may need elevated foundations with flood vents. Fairfield's floodplain manager makes the call; we build to the approved plans.
Do you pour foundations near Fairfield?
Yes. We also pour foundations in Bridgeport, Westport and Weston, and across Fairfield County.
