Parts of Guilford 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.

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