Renovation contractor in Belmont, MA
Kitchens, bathrooms and full renovations in Belmont, managed by a licensed Massachusetts Construction Supervisor from plans to 100% complete.
Magno & Co renovates homes in Belmont, MA, from its base at 55 Davis Square, Somerville. Founder Mateus Magno (MA Construction Supervisor CS-123658, HIC #220484, Lead-Safe Renovator Supervisor) manages kitchens, bathrooms, full renovations and owner's representative projects through final inspection, and pulls the permits in Belmont on the jobs he builds. Belmont still uses PDF permit packets, and work near wetlands may need Conservation Commission approval first.

Renovating in Belmont: what to know
Belmont has about 10,881 homes: 57% were built in 1939 or earlier and 83% (9,062) before 1970 (U.S. Census, ACS 2020–2024), so most homes here predate 1978 and many renovations disturb paint covered by lead-safe work rules. That's why every Belmont job I run starts with a walkthrough for lead paint, old wiring, old plumbing and framing, so they're priced up front as much as possible.

Permits in Belmont
- Office of Planning & Building, Building Division, 19 Moore St, 2nd floor, Belmont, MA 02478 · 617-993-2650 · official page
- Belmont has no online permit portal yet (the town says an OpenGov portal is coming); permits use the town's PDF application packets.
- Massachusetts requires a licensed Construction Supervisor to oversee most structural work, and an HIC-registered contractor for work on existing owner-occupied 1–4 family homes. I hold both (CS-123658 · HIC #220484) and pull the permits myself on the jobs I build.
- Planning a backyard cottage? Since February 2, 2025, state law allows one ADU up to 900 sq ft (or half the main home, if smaller) by right in single-family zones, including in Belmont. mass.gov · ADU Studio
Local rules that can affect your project

- Wetlands: work in a wetlands buffer zone or riverfront area may need Conservation Commission approval before the building permit. Source
- Energy code: Belmont uses the Massachusetts Specialized Opt-in Energy Code (since 1/1/2025). It mainly changes the rules for new construction; I confirm what applies to your project. Source

Is my Belmont house subject to demolition delay?
Only if it's on Belmont's List of Significant Buildings. If it is, demolition needs review first. I check the list before we plan an addition or a teardown.
