Buffalo conditions

Building adu for Buffalo conditions

Buffalo'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 Buffalo's Northeast winters the envelope and mechanical sizing matter more per square foot than they would on the main house.
