Building Capacity:
Building capacity of 0 sq ft is not enough for a backyard cottage
Newton sets FAR (Floor Area Ratio) limits for residential lots which dictates your lot’s capacity, or how much may be built. It’s not possible to definitively calculate your capacity without taking real-world measurements, so this is an estimate. We estimate that your lot does not have sufficient capacity to build new structures. We estimated your habitable space; contact us if you’d like to learn more.
