Hamilton, MA
Horse country. Big lots, sandy soil and a strict wetlands bylaw.
Hamilton grew from farms to estates to horse properties to large-lot neighborhoods after Route 128. Zoning runs up to 80,000 sq ft lots. There's room to build, and a bylaw that decides where.

Know before you build
Hamilton's wetlands bylaw sets two lines.
Hamilton's own bylaw is stricter than the state act, with a no-disturbance zone and a no-build zone that depend on when your lot was created.
Older house lots: 25 and 50 feet
On residential lots occupied or permitted by the end of 2007, there's a 25-foot no-disturbance zone and a no-build zone out to 50 feet from a wetland.
Source: Hamilton Wetlands Protection Bylaw ↗Everything else: 50 and 75 feet
In other cases the no-disturbance zone is 50 feet and the no-build zone runs to 75. Around vernal pools, the whole 100 feet is no-disturb.
Source: Hamilton Wetlands Protection Bylaw ↗What the zones allow
The no-disturbance zone allows no construction or vegetation removal, and not even dumping leaves or clippings. The no-build zone bars anything that needs a building permit, but driveways and fences may be allowed.

From May to September, sprinklers and irrigation systems on town water can't run from 8 AM to 8 PM, and irrigation systems need rain sensors. When the Ipswich River runs low, the town can ban sprinklers entirely, including on private wells.

The Hamilton Historic District on Bay Road reviews changes visible from a public way. The current handbook exempts walls, fences and at-grade walks and terraces, though the Commission has proposed reviewing walls and fences. Check before you build.

What we build here
Services in Hamilton.
Big Hamilton properties suit big patios, fire pits and outdoor kitchens. Fences are a natural fit on horse properties.
Hamilton ground
Sandy and fast-draining, with wet ground by the river.
From the state's historical survey of the town.
- Central & east
- Sandy outwash soils drain fast: great for patio bases, thirsty for lawns.
- Upland hills
- Well-drained loamy till on Brown's, Willow and Sagamore Hills.
- Miles River & swamp
- Very poorly drained muck near the Miles River and Wenham Swamp.

How close to a wetland can I build a patio in Hamilton?
It depends on when your lot was created. Older house lots have a no-build zone out to 50 feet, other lots out to 75. Anything needing a building permit can't go in that zone.
Can a fence go near a wetland in Hamilton?
The no-build zone bars anything needing a building permit, but the bylaw says fences and driveways may be allowed. We'll check with the Commission.
Can I water my new lawn during the day?
Not with sprinklers from May to September: they're banned from 8 AM to 8 PM on town water. Early morning or evening watering is the plan.
