New Haven conditions
What adu projects in New Haven actually take
New Haven's lot rules, setbacks, and parking requirements decide what's buildable before any design starts, so the firms we match confirm zoning feasibility on your specific parcel first. A small footprint loses heat fast, so in New Haven's Connecticut winters the envelope and mechanical sizing matter more per square foot than they would on the main house.
