Custom Modular
ADUs in
Hingham, MA.

Hingham's historic district overlays add a layer of design review that doesn't exist in most other Plymouth County towns. ADUs in historic districts require Historic Commission sign-off — which Mike handles as part of the permitting process. Outside the historic zones, Hingham follows the standard 2024 ADU framework.

ADUs in Hingham

A Second Home
on Your Hingham Lot.

For families in Hingham looking to bring aging parents home, add rental income, or carve out a serious home office without leaving the property, modular ADUs are the fastest, most predictable way to add livable square footage. Same factory-built quality as a full custom modular home — just compressed into 400–900 square feet.

Building in Hingham (Hingham Center, Crow Point, World's End, Downtown Hingham, South Hingham, and the rest) means working through Hingham's specific permitting, septic, and zoning rules. Mike has been doing exactly that for 40+ years. He confirms by-right eligibility, setbacks, and septic capacity during your free site walk — before plans are drawn, before contracts are signed, before you're financially committed.

Pricing is identical to our full modular homes: $250 per square foot, locked in writing before groundbreaking. A 600 sq ft ADU is approximately $150,000. A 900 sq ft ADU is approximately $225,000. Turnkey — design, permits, factory build, foundation, crane set, finish work, final inspection.

Why ADUs in Hingham with Mike
  • 40+ years of Hingham permitting experience — knows every inspector personally
  • Historic district-aware ADU builds — local insight that off-South-Shore builders don't have
  • Handles septic capacity, setbacks, and zoning verification before you sign
  • Single set day on your Hingham property — minimal disruption
  • Fixed $250/sqft price + timeline locked before groundbreaking

"Every Hingham ADU project starts with a site walk. Before plans, before pricing, before anything else — I want to stand on your lot and confirm what's actually buildable. That step alone saves families months of wasted design fees on projects that wouldn't have cleared Hingham's rules."

What ADUs Are Used For

Four Ways
Hingham Families
Use ADUs.

Same shell, very different lives inside. The best ADU is the one designed around what your family actually needs — not a generic template.

01
In-Law Suite

Bring aging parents home without giving up privacy on either side. Single-floor layouts with wider doorways, walk-in showers, and zero stairs — designed for aging in place from day one.

02
Rental Income

Hingham has strong long-term rental demand for well-designed ADUs. Coastal towns command premiums on short-term platforms during summer. Many owners use rental income to recover a meaningful portion of their build cost.

03
Home Office / Studio

A real, separated workspace — not a corner of the dining room. Insulated, climate-controlled, hard-wired internet. Walk across the yard, close the door, do the work.

04
Guest House

Visiting family. College kids home for summer. Friends in town. A proper guest house means your main home stays your main home — no fold-out couches, no shared bathrooms.

05
Adult Children Returning

For families whose adult kids are saving for a first home or finishing graduate school. Privacy for both households without the cost of separate housing during a transitional season.

06
Property Value Add

A permitted, code-compliant ADU adds documented square footage and a separate income stream — both of which appraise. Well-designed ADUs typically support and grow your Hingham property's resale value.
