Foundation work in Darien
28% of Darien's homes were built before 1940, many on fieldstone, brick or early concrete foundations. Additions to those houses need new footings dug carefully beside the old walls so we don't undermine them.
Parts of Darien 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 Darien was built in 1957, older than the 1960s house that's typical statewide. That's older than nearby Stamford, where the median is 1972.

Concrete foundations in Darien: questions
Do I need a permit for a foundation in Darien?
Yes. New foundations, additions and garages need a building permit from Darien'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 Darien?
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. Darien's floodplain manager makes the call; we build to the approved plans.
Do you pour foundations near Darien?
Yes. We also pour foundations in Stamford, Norwalk and New Canaan, and across Fairfield County.
