Wenham, MA
Wenham: estates, a lake, a swamp, and a bylaw that protects them.
Big lots, old Main Street homes and a lot of water: Wenham Lake, the Miles River and Wenham Swamp. Wenham's own water resources bylaw reaches further than the state's, so the plan starts with where the water is.
Know before you build
Wenham's water rules come first.
Wenham's Water Resources Protection Bylaw goes well beyond the state act. For a single residential lot, here's what it means in practice.
- 01
100 feet, and 200 on waterways
The regulated zone covers land within 100 feet of wetlands and 200 feet of lakes, ponds, rivers and streams. The Commission discourages any work there.

30 and 50 feet on a house lot
On a single residential lot, work closer than 30 feet to a resource area, or building closer than 50 feet, is presumed to harm it. The Commission may require a naturally vegetated strip at least 50 feet wide, or 100 on waterways.

Main Street historic district
The Wenham Historic District runs along Main Street from the Beverly line to the Hamilton line. At-grade terraces, walks and driveways are excluded from review, but walls and fences aren't on the exclusion list, so they likely need a Certificate of Appropriateness.

No daytime sprinklers, even on wells
From May 1 to September 30, sprinklers and irrigation systems can't run from 9 AM to 5 PM, on town water and private wells alike. When the Ipswich River runs low, non-essential use is banned.

Fence heights
Boundary fences up to 8 feet appear to be allowed, but view-blocking fences are limited to 36 inches within 20 feet of the street. This is from a third-party copy of the zoning bylaw, so confirm with the building department.

Wenham ground
Sandy uplands, mucky lowlands.
From the state's historical survey of the town. The land is mostly level, with Lord's Hill the high point at 173 feet.
- Central Wenham
- Sandy, fast-draining soils. Good for patio bases, tough on lawns in July.
- Northwest
- Wenham Swamp's mucky soils, draining to the Ipswich River.
- Lawns
- The Water Department advises reseeding before mid-May or after Labor Day, never in summer.
What we build here
Services in Wenham.
Patios, pavers, walls and fences, plus kitchens and pools for Wenham's larger properties.
On a Wenham estate lot there's usually plenty of room for a patio. The question is where the 50-foot line from the water falls.
We find it on the first visit.

How close to Wenham Lake can I build a patio?
Wenham's bylaw presumes building within 50 feet of a resource area harms it, and reaches 200 feet from lakes and ponds. Most patios get designed to stay well back.
I'm on a private well. Can I run my sprinklers midday?
No. Wenham's May-to-September 9-to-5 sprinkler ban applies to private wells too.
Do I need approval for a fence on Main Street?
Likely. Fences and walls aren't on the historic district bylaw's exclusion list, so plan on Historic District Commission review.
