Hingham’s zoning bylaws divide the town into residential, commercial, industrial, and open-space districts, each with its own list of allowed uses and its own limits on lot size, building height, and setbacks; projects that don’t fit those rules need a special permit or a variance from the Zoning Board of Appeals. The bylaw is adopted under Massachusetts General Laws Chapter 40A, which also governs how relief is granted and appealed.1Massachusetts Government. Massachusetts General Laws Chapter 40A – Zoning Before you draw plans, hire a contractor, or sign a purchase and sale agreement, find your district on the zoning map and read the rules that apply to it.
Find Your District First
Every parcel in Hingham sits in one zoning district, and that designation controls what you can do with the land. The town maintains five residential tiers (Residence Districts A through E) along with Business A and B, Office Park, Waterfront Business, Waterfront Recreation, Industrial, Industrial Park, Limited Industrial Park, Business Recreation, and Official and Open Space.2Town of Hingham. Hingham Zoning By-Law Section III
Each district has a Use Table in the bylaw. The table shows whether a given activity is allowed by right, requires a special permit, or is prohibited. A retail shop that’s fine in Business A may be banned in an industrial district. A single-family home allowed by right in a residential zone may need a special permit in a waterfront district. Pull your map reference and the Use Table before anything else; projects designed around the wrong assumption can cost months of rework.
Dimensional Rules That Shape What You Can Build
Even when a use is allowed, your structure has to fit within the physical envelope that Section IV of the bylaw sets for the district.3Town of Hingham. Hingham Zoning By-Law Section IV The dimensional table controls minimum lot area, frontage, height, setbacks, and lot coverage.
In the residential districts, the numbers vary. Residence District A, the densest, requires a 20,000 square-foot minimum lot with 125 feet of street frontage. Residence Districts B and E both require 30,000 square feet. Residence District C requires 40,000.3Town of Hingham. Hingham Zoning By-Law Section IV Residential building height is generally capped at 35 feet or two and a half stories. In Residence District A, the front setback is 25 feet with 15 feet on the sides and rear.
Lot coverage limits restrict how much of your lot can be covered by impermeable surfaces like roofs and pavement. These rules work together to preserve spacing, light, and emergency access. The table is dense, so pull the row for your specific district before drafting plans.
Special Permit or Variance: Which One You Need
When a project doesn’t fit cleanly, two paths to relief exist. They are not interchangeable, and treating them as such is one of the most common mistakes property owners make.
Special Permits
A special permit is for uses the bylaw already allows in your district but only with board oversight. The Use Table flags these, directing you to either the Board of Appeals or the Planning Board. The board evaluates whether your specific proposal, at your specific lot, will work without creating undue problems for the neighborhood. Under state law, approval requires a supermajority: four votes on a five-member board, or two-thirds of a larger board.4Massachusetts Government. Massachusetts General Laws Chapter 40A Section 9 One or two skeptical members can block a project.
Variances
A variance asks the town to waive a rule entirely. Massachusetts law requires you to prove three things: that the shape, topography, or soil conditions of your lot create a hardship unique to your property and not shared with the surrounding neighborhood; that enforcing the rule would cause substantial hardship; and that granting relief won’t harm the public interest or undermine the purpose of the bylaw.5General Court of Massachusetts. Massachusetts General Laws Chapter 40A Section 10 A variance cannot authorize a use that the bylaw prohibits in your district. It’s limited to dimensional relief, like reducing a setback or exceeding a height limit. The hardship test is strict; thinly supported variances get overturned on appeal.
Overlay Districts That Add Rules on Top
Overlay zones layer extra requirements on top of your base district without replacing it. Three matter most to Hingham owners.
Flood Plain Protection
As a coastal town, Hingham maintains a Flood Plain Protection Overlay District covering areas identified on FEMA maps as having at least a one-percent annual chance of flooding.6FEMA. Change Your Flood Zone Designation Properties inside the overlay face additional construction requirements, including elevation standards and limits on what can be built in the floodplain.
Historic Districts
The Historic Districts Commission reviews all proposed exterior alterations, renovations, and new construction within Hingham’s local historic districts.7Hingham, MA. Historic Districts Commission If your property is inside one, you need Commission approval before changing the exterior, even if the zoning bylaw and building code would otherwise let the work proceed. The review is separate from zoning, and skipping it can lead to an order to undo completed work.
Downtown Hingham Overlay
The Downtown Hingham Overlay District applies special use and design rules along and near Main Street, North Street, and South Street. Certain uses inside the overlay require special permits with criteria beyond the standard evaluation, aimed at keeping pedestrian-oriented commercial activity in the primary downtown area.2Town of Hingham. Hingham Zoning By-Law Section III
Recent State Laws That Override Local Rules
Two Massachusetts statutes have reshaped what Hingham can and cannot regulate.
Accessory Dwelling Units Allowed By Right
The Affordable Homes Act, passed in August 2024, legalized accessory dwelling units statewide as of February 2, 2025. Every Massachusetts city and town must now allow at least one ADU by right on any property in a single-family residential zoning district.8Metropolitan Area Planning Council. Accessory Dwelling Units (ADUs) in the Commonwealth Owner-occupancy requirements are prohibited, and the amount of additional parking a town can demand is limited. Short-term rental use of an ADU can still be regulated locally.
For Hingham homeowners, this means an in-law suite over the garage, a basement apartment, or a converted carriage house no longer requires a special permit or variance in the Residence Districts. The town retains control over design and dimensional standards but cannot ban the use itself.
MBTA Communities Act
Because Hingham is served by commuter rail and ferry, Section 3A of Chapter 40A requires the town to adopt at least one zoning district that permits multi-family housing by right, without age restrictions and suitable for families with children. The district must allow at least 15 units per acre and sit within half a mile of a transit station or ferry terminal.9Massachusetts Government. Multi-Family Zoning Requirement for MBTA Communities
Non-compliant communities lose eligibility for several state funding programs, including the Housing Choice Initiative, the Local Capital Projects Fund, and the MassWorks infrastructure program, and face potential civil enforcement and fair-housing liability.9Massachusetts Government. Multi-Family Zoning Requirement for MBTA Communities Hingham’s proposed compliance plan would create a multi-family overlay near the ferry terminal and commuter rail stations with capacity of roughly 1,490 units. If you own near those transit areas, the overlay could meaningfully change what’s buildable on your land.
If Your Property Predates the Current Rules
Buildings and uses that were lawful before current zoning took effect are legally non-conforming, or grandfathered. The bylaw cannot force you to remove a structure or stop a use that was legal when it began.10Massachusetts Government. Massachusetts General Laws Chapter 40A Section 6
Changes to a non-conforming structure or use require a finding from the permit granting authority that the modification won’t be “substantially more detrimental” to the neighborhood than what exists.10Massachusetts Government. Massachusetts General Laws Chapter 40A Section 6 One exception matters: alterations to a single-family or two-family home that don’t increase the non-conforming nature of the structure can proceed without that finding. Adding a deck on the conforming side of your lot is usually fine. Pushing a wall closer to a lot line that already violates the setback usually isn’t.
Abandonment is the other risk. State law allows a town’s bylaw to treat a non-conforming use discontinued for two years or more as abandoned.10Massachusetts Government. Massachusetts General Laws Chapter 40A Section 6 Once abandoned, the grandfathered status is gone and current zoning applies. If you own a non-conforming property and pause use, document continued activity or clear intent to resume.
Filing for Zoning Relief
Special permit and variance applications go to the Board of Appeals. Download the application forms and checklist from the Town of Hingham website.11Hingham, MA. Application Forms Each application identifies the property by assessor’s map reference and cites the exact bylaw section you need relief from.
You’ll need a certified plot plan from a registered land surveyor showing existing structures, proposed changes, and precise measurements to all lot lines. The plan is the backbone of the application; a sloppy one will stall the process. Gather your deed, any prior zoning decisions on the property, and a written narrative explaining what you’re proposing and why the standard for relief is met.12Hingham, MA. Board of Appeals Guide
File a complete package with the Town Clerk and pay the filing fee. Current fees:
- Residential variance: $300
- Commercial variance: $300 for the first 2,000 square feet, plus $100 for each additional 1,000 square feet
- Special permit: $300 for the first 2,000 square feet, plus $100 for each additional 1,000 square feet
- Sign permits: $300
- Comprehensive permit: $250 per unit, plus postage and legal notice costs
- All other applications: $400
These are administrative fees only. Budget separately for the surveyor’s plot plan, which can run from several hundred to several thousand dollars depending on the lot, and for any attorney or architect helping you present.11Hingham, MA. Application Forms
The Public Hearing and Abutter Notice
Once your application is in, the town schedules a public hearing. Massachusetts law defines “parties in interest” broadly: direct abutters, owners of land across the street, and abutters to the abutters within 300 feet of your property line all receive mailed notice, including landowners in neighboring towns if they fall within that radius.13General Court of Massachusetts. Massachusetts General Laws Chapter 40A Section 11 Notices typically go out about two weeks before the hearing.
At the hearing, you present and the board hears from abutters and other interested parties. Be ready to show how your proposal meets the legal standard for the relief you’re seeking. For a special permit, that the use won’t be detrimental to the neighborhood. For a variance, the hardship unique to your lot. Board members will press on specifics, and neighbor opposition can shape the vote even when it isn’t a technical legal objection.
The 20-Day Appeal Window
After the board votes, it files a written decision with the Town Clerk. A 20-day appeal window runs from that filing date. During those 20 days, no construction permits are issued and no work begins, even on approved projects.12Hingham, MA. Board of Appeals Guide Any aggrieved person, whether or not they spoke at the hearing, can appeal to land court, superior court, or district court by filing within that window.14Massachusetts Government. Massachusetts General Laws Chapter 40A Section 17
A court doesn’t retry the application. It reviews whether the board acted within its legal authority and whether the record supports the decision. Boards get substantial deference, and courts generally uphold decisions unless the board acted arbitrarily, abused its discretion, or exceeded its authority. The 20-day deadline is absolute. Miss it by a day and you lose the right to appeal.
What Happens If You Skip the Process
Hingham’s building inspector enforces the bylaw. The inspector can withhold building permits for work that would violate zoning and refuse occupancy permits for uses that aren’t allowed in a district.15General Court of Massachusetts. Massachusetts General Laws Chapter 40A Section 7 Building without zoning approval exposes you to more than a stop-work order.
State law caps zoning fines at $300 per violation, but each day a violation continues is a separate offense.15General Court of Massachusetts. Massachusetts General Laws Chapter 40A Section 7 A violation that runs two months can generate over $18,000 in penalties. Superior court and land court can order you to tear down a non-compliant structure or stop an unauthorized use. Anyone can request enforcement in writing, and the building inspector must respond within 14 days with a decision and reasons.
Time limits do exist, which matters when buying an older property. If a building was constructed under a valid permit and used consistently with it, the town generally has six years from the start of the alleged violation to act. For structural violations, the window is ten years.15General Court of Massachusetts. Massachusetts General Laws Chapter 40A Section 7 After those deadlines, enforcement is barred.
