Massachusetts does not have a state law that forbids keeping an unregistered vehicle on private property in Massachusetts. The registration requirement in Chapter 90 applies to vehicles on public ways, not to a car sitting in your driveway or behind your house. The real restrictions come from your city or town, and they can be strict: many municipalities limit you to one unregistered vehicle on a residential lot, require permits or screening for more, and can turn an ignored citation into a lien on your property tax bill.
What State Law Actually Requires
Chapter 90, Section 9 prohibits operating, pushing, drawing, or towing an unregistered vehicle on any public way, and bars owners from letting an unregistered vehicle remain on a public way.1General Court of Massachusetts. Massachusetts General Laws Chapter 90 Section 9 The statute’s reach stops at the edge of the road. If your unregistered car never touches a public street, Chapter 90 itself does not penalize you for storing it.
The definition of “motor vehicle” under Chapter 90 also matters. It excludes vehicles that cannot exceed twelve miles per hour and are designed for off-road use, along with railroad cars, wheelchairs, electric bicycles, and motorized bicycles.2General Court of Massachusetts. Massachusetts General Laws Chapter 90 Section 1 Anything outside that definition never needed registration in the first place.
If you do drive an unregistered vehicle on a public road, a first conviction under Section 9 carries a fine of up to $100, and any subsequent offense a maximum of $1,000.1General Court of Massachusetts. Massachusetts General Laws Chapter 90 Section 9 A conviction is also treated as evidence of negligence in any lawsuit arising from a crash.
What Your City or Town Almost Certainly Restricts
Municipalities in Massachusetts use their police powers to regulate how vehicles are stored on residential property, and the rules vary from one town to the next. A typical bylaw limits a residential lot to one unregistered vehicle. Keeping more than that generally requires a permit from the selectboard or city council, sometimes after a public hearing, and often with conditions: a time limit, screening from public view, or restrictions on where on the lot the vehicles can sit.
Vehicles stored inside an enclosed building, such as a garage, are frequently exempt from these limits altogether. Farms, nurseries, and industrial properties usually get more leeway than purely residential ones, and commercial or industrial zoning tends to allow more flexibility than residential zoning.
Because these rules are local, the specific answer for your property lives in your town’s bylaw or zoning ordinance. Calling the planning department or zoning board before you park a project car in the yard is faster and cheaper than contesting a citation later.
How Bylaw Enforcement Escalates
The enforcement path for local violations follows a structured process. When the municipality issues a notice of violation, you have 21 days to pay the fine or request a hearing before a municipal hearing officer. Ignore the notice, and the town sends a follow-up letter (with a processing fee of up to $10) that gives you another 30 days to pay. After that, interest and additional penalties accrue, and the unpaid balance can be added to your property tax bill or become a lien against the real estate.3General Court of Massachusetts. Massachusetts General Laws Part I Title VII Chapter 40u Section 12 The lien stays in place until every dollar is paid, including filing and release costs.
Under many local bylaws, each day of a continuing violation counts as a separate offense. A modest starting fine for a junk car in the yard can snowball quickly if the notices go in a drawer.
When the Abandoned-Vehicle Statute Takes Over
Chapter 90, Section 22B applies to abandoned vehicles regardless of whether they sit on public or private property. Abandoning a vehicle on a public or private way, or on someone else’s property without permission, carries a civil penalty of $250 for a first offense and $500 for each subsequent abandonment, plus the municipality’s towing, storage, and disposal costs.4General Court of Massachusetts. Massachusetts General Laws Chapter 90 Section 22B
In municipalities that have adopted the non-criminal enforcement provisions of Section 22B, an officer or designee will tag the vehicle with the date, location, description, and a notice explaining the hearing process and the timeline before it may be towed. If the vehicle’s value is less than the cost of removing and storing it for three days, the municipality can direct a towing company to take it and dispose of it as refuse.4General Court of Massachusetts. Massachusetts General Laws Chapter 90 Section 22B A conviction for abandonment can also lead the RMV to revoke your license for up to three months and block you from registering another vehicle for a year.
Parking a dead car on a neighbor’s land or leaving one on the street is abandonment territory, and the penalties there arrive faster and heavier than routine bylaw enforcement.
Exceptions That Let You Keep the Vehicle Legally
Antique Plates
A vehicle over 25 years old maintained for exhibitions, club events, parades, or similar public-interest activities can receive antique registration plates through the RMV.5Massachusetts Registry of Motor Vehicles. Application for an Antique Motor Vehicle Plate or Year of Manufacture Registration Plate Antique plates come with use restrictions: no regular passenger or goods transportation, though test drives to prepare for events and trips to a repair shop are permitted. Because a vehicle with antique plates is registered, it is not “unregistered” for purposes of either state law or local bylaws. For collectors, this is the cleanest way to store a vintage car on the property.
Farm Tractors and Off-Road Equipment
Farm tractors that cannot exceed twelve miles per hour and are designed for off-road use fall outside the definition of “motor vehicle” and need no registration.2General Court of Massachusetts. Massachusetts General Laws Chapter 90 Section 1 Section 9 also permits unregistered tractors, trailers, and trucks to travel short distances on public roads for agricultural purposes: up to half a mile if uninsured, or up to two miles if insured.1General Court of Massachusetts. Massachusetts General Laws Chapter 90 Section 9 For longer road use, Section 5 provides farmer registration plates for vehicles principally used for farm-related activity; these plates cannot be used on a passenger vehicle.6General Court of Massachusetts.

Restoration Projects
State law does not carve out a blanket exemption for restoration projects. If the vehicle stays on your property and is not visible from the road, state-level problems are unlikely, but the local bylaw still governs. Many towns allow restoration if the vehicle is stored inside a building or behind screening; some require a permit for projects that will run longer than a set period. Check the bylaw before you start.
Fighting a Citation
The most straightforward defense is showing the rule does not apply to your situation. If the vehicle is inside a garage and the bylaw exempts enclosed buildings, the citation fails. If the vehicle has antique plates, it is registered, and the violation does not apply. Dated photographs of the vehicle’s location and condition are the most useful evidence.
Procedural defenses carry real weight under Chapter 40U. The statute requires proper notice and an opportunity for a hearing before penalties escalate, and the property owner of record must be notified by certified mail before a lien can be placed.3General Court of Massachusetts. Massachusetts General Laws Part I Title VII Chapter 40u Section 12 A town that skipped the notice step, imposed penalties without offering a hearing, or failed to follow its own procedures has given you grounds to challenge the action.
If the underlying zoning rule is the problem, a variance or special permit through the local zoning board of appeals is another path. A variance requires showing that strict application creates a hardship unique to your property. A special permit is generally easier and often turns on showing that the storage will not harm the neighborhood. Either route runs through a public hearing.
Selling a Property With Unregistered Vehicles on It
Massachusetts follows caveat emptor in real estate. Sellers are required to disclose only two specific conditions: the presence of lead paint and the existence of a septic system. There is no state law requiring you to volunteer that your property has bylaw violations tied to unregistered vehicles.
Lying in response to a direct question is a different matter and can expose you to fraud liability. And any outstanding municipal fine that has become a lien on the property tax bill will surface in a title search and must be cleared before closing. Resolving the vehicle issue before listing (by removing the car, registering it, or bringing storage into compliance) is almost always cheaper than dealing with a lien at the closing table or a buyer who walks.
