What should Boylston homeowners know before adding on?
Plan around the reservoir, the town’s own utilities and its historic center. Boylston is a small, mostly residential town of 4,849 people (2020 census), and a few local details shape how an addition goes.
- The Wachusett Reservoir. About 5,000 acres of the reservoir sit in the northwest part of town. Land near the reservoir and its tributaries falls under the state’s watershed protection rules, which limit building close to the water.
- Town-run light and water. Boylston has its own Municipal Light Department and Water District, so a new service or a bigger electrical panel is coordinated with them.
- A historic district commission. The town has a Historic District Commission. If your house sits inside a local historic district, exterior changes can need its approval before a building permit.
- Wells, septic and wetlands. If the house runs on a septic system, adding a bedroom brings in the state’s Title 5 rules through the Board of Health, and work near wetlands goes to the Conservation Commission.
Town offices are at 221 Main Street. Background on the town is on Wikipedia.

Do I need a permit for an addition in Boylston?
Yes. An addition needs a building permit from the town and inspections as it goes. We prepare and file the permit and meet the inspectors on site.
Does adding a bedroom affect my septic system?
It can. Under Title 5, a septic system is sized by the number of bedrooms, so the Board of Health needs to confirm the system can handle one more before the building permit is issued. We raise this at the first visit so it is settled early.
Can I build near the reservoir?
It depends on how close the house is to the water and its tributaries. Watershed protection rules restrict building in those zones, so we look at the lot and talk through what review applies before any design work.
How far do you travel to Boylston?
Not far. Our office is in Northborough, which borders Boylston, so Boylston is one of the closest towns we serve.
Can we stay in the house during an addition?
Yes, for most of the job, since most of an addition is built outside the existing walls. Before work starts we go over which rooms will be affected and when.
