Ron Morgan Construction – ADU Contractor and General Builder in Massachusetts
Ron Morgan Construction is a Massachusetts-based general contracting company offering both commercial and residential construction services, with a particular focus on Accessory Dwelling Units (ADUs). They handle projects from initial feasibility through to the final occupancy permit, managing design, permitting, and construction under one roof.
An Accessory Dwelling Unit is a smaller, self-contained home located on the same property as a primary residence. It can be attached to the main home, built as a standalone structure, or created by converting existing space such as a basement, attic, or garage. ADUs are commonly used to house family members, generate rental income, or provide independent living space for aging parents.
ADU Services Offered by Ron Morgan Construction
As an experienced ADU builder, Ron Morgan Construction works with homeowners across Massachusetts to plan, permit, and construct accessory dwelling units in a range of sizes and configurations. Their ADU offerings are grouped into practical categories based on square footage and layout:
- ADUs 300–500 sq ft – Compact studio or one-bedroom units suited to tighter lots and budgets. These are well-suited for guests, a home office, or aging-in-place arrangements. They typically feature efficient layouts with a full bath and kitchenette, and can be completed with shorter site work timelines.
- ADUs 600–700 sq ft – Roomier one- to two-bedroom units with a full kitchen, better storage, and improved circulation. These work well for multigenerational living or long-term guests.
- ADUs 700–900 sq ft – Typically two-bedroom, two-bath units with larger living areas, pantry space, and utility closets. These are often considered where local bylaws permit rentals.
- Above-Garage ADUs – Either adding a new garage with an ADU above, or building on top of an existing garage structure.
- Addition to Existing House – Expanding the home to include a new ADU with two means of egress.
- Conversions (Inside the House) – Reconfiguring attics, basements, or existing interior space to create a JADU or attached accessory dwelling unit.
Ron Morgan Construction is also an authorized Boxabl dealer, meaning they can price, permit, and install Boxabl prefabricated units alongside custom ADU builds, giving homeowners an additional option to consider.
Their process covers the full scope of an ADU project:
- Locating and confirming ADU placement on the property
- Supplying architectural drawings tailored to the homeowner's needs
- Civil engineering for site plans and utility connections
- Referring clients to lenders familiar with ADU financing
- Delivering a turnkey residence upon receipt of the occupancy permit
Massachusetts ADU Law and Local Permitting
On August 6, 2024, Governor Healey signed the Affordable Homes Act (Chapter 150 of the Acts of 2024) into law. Section 8 of this legislation amends the Zoning Act to allow ADUs up to 900 square feet to be built by right in single-family zoning districts across Massachusetts. This change has made it more straightforward for homeowners to pursue granny flat, in-law suite, or backyard cottage projects without requiring special zoning variances in many cases.
Ron Morgan Construction handles zoning, historic, building, and inspection permits as part of their service. Most projects begin with a 20–30 minute consultation and a site walkthrough to confirm feasibility. New construction ADUs typically start at around $90,000, with a concept-to-keys timeline ranging from 5 to 10 months depending on scope and permitting requirements.
Beyond ADU work, Ron Morgan Construction also takes on residential additions, remodels, and renovations, as well as commercial ground-up builds and tenant improvements for Massachusetts businesses.
