Local Context

Why Wakefield is a strong market for ADU and excavation work.

Wakefield and Sanbornville sit on the NH side of our driveway. Lake lots and village streets both show up in the same week. We already know the soils and the planning office.

Setbacks

Front, side, and rear in Wakefield.

NH RSA 674:71-73 (HB 577) — one ADU by right on a single-family lot

Wakefield and Sanbornville sit next to our Maine yard. RES-I is the district we quote most. Shorefront lots also sit under the state shoreland act.

District	Front	Side	Rear	Lot / cover
RES-I · primary Residential I Table 2 standard lots. Wetland setback 30 ft. Side can drop to 10 ft on some grandfathered lots.	20 ft	20 ft	10 ft	43,560 sf · 45% building
RES-II Residential II — Shorefront Generally within 500 ft of lakes. 150 ft shoreline frontage. NH Shoreland Act still applies.	20 ft	20 ft	10 ft	43,560 sf · 45% building

VR Village / Residential	20 ft	10 ft	10 ft	21,780 sf · 45% building

ADU setbacks match the district. We do not treat Sanbornville as a separate town — it is Wakefield.
Lake lots need the shoreland setback in addition to the table above.
