Private and Class VI roads are a common feature across New Hampshire's rural and mountain communities, and recent legislation has changed how building permits work on them. Before you fall in love with a property tucked down a quiet lane, our real estate agents want you to walk through what that means for you.

Why Private Roads Are So Common in New Hampshire

Many of the state's most desirable properties, particularly in the White Mountains and Lakes Region, sit off private or Class VI roads. Many rural properties are accessed by private roads or Class VI highways, where municipal maintenance and services may be limited or nonexistent.

That arrangement can work beautifully when it's set up right. It can also become a source of real headaches when it isn't. Understanding the difference and the legal changes that now govern building permits on these roads will save you from surprises later.

What Makes a Private Road Different

A private road shifts maintenance responsibility away from the town and onto the property owners who use it. That distinction affects several things you'll want to evaluate closely:

• Snow removal and grading costs, which are split among road users rather than covered by tax dollars
• Road surface quality, since gravel and dirt roads require more frequent upkeep than paved ones
• Emergency access, particularly during mud season or after a heavy storm
• Insurance and financing, as some lenders scrutinize private road access more closely

New Hampshire Just Changed the Building Permit Rules

Under the state's longstanding permit law, a building permit generally could not be issued unless the lot had frontage on a qualifying road, such as a Class V or better highway, or met one of the statute's exceptions. For properties on private or Class VI roads, the law historically required an additional approval process involving the municipality's governing body, along with recorded notice limiting municipal responsibility and liability.

That case-by-case approach created a patchwork of outcomes across the state. Some towns capped how far a lot could sit from a maintained road. Others attached conditions to one owner's permit that never applied to the neighbor next door. As detailed in this recent legal analysis of the 2025 reforms, that inconsistency is exactly what lawmakers set out to fix.

What Changed for Private Roads

Effective September 13, 2025, municipalities gained a new option for handling permits on private roads. A town may adopt a formal policy establishing standards for private roads. If a road complies with that policy, the governing body can act without first obtaining review and comment from the planning board. Towns are not required to adopt such a policy, so buyers should ask how the municipality handles building permits on private roads.

What Changed for Class VI Roads

A separate reform for Class VI roads took effect July 1, 2026. An owner can now obtain a building permit without governing-body approval by meeting the requirements established under the amended law. An owner can secure a building permit by signing and recording the required liability waiver rather than seeking governing-body approval. That waiver generally needs to acknowledge a few things:

• The municipality will not maintain the road or provide services to the property
• The town accepts no responsibility for losses tied to that lack of services
• Responsibility for services the municipality will not provide falls on the applicant

The new rule also requires the owner to show that the lot and any structures on it can be insured, which is a fresh requirement worth discussing with your insurance provider well before closing.

The Road Maintenance Agreement Still Matters

Even with these legislative changes, the road maintenance agreement remains one of the most important documents in the transaction. This is the private contract that spells out who pays for what, how decisions get made, and what happens when someone doesn't hold up their end.

A solid agreement typically addresses the following:

• Cost allocation among the properties that share the road
• A clear process for collecting dues and handling nonpayment
• Who is authorized to hire plow drivers or contractors
• How disputes between neighbors get resolved

If no formal agreement exists, that's not automatically a dealbreaker, but it is a flag worth discussing with your attorney and lender before you move forward. Ask yourself whether you're comfortable relying on informal, handshake arrangements for something as important as winter access to your home.

Zoning Can Still Complicate Things

Meeting the state's permit requirements does not automatically clear local zoning. Many town ordinances still require frontage on a paved or town-maintained road, so a property owner building on a private or Class VI road may need a variance from the zoning board of adjustment regardless of the new state rules. This is exactly the kind of detail worth confirming before you write an offer.

Common Questions About Private and Class VI Road Properties

Do I still need to plow my own driveway on a private road?

Yes. Road maintenance agreements typically cover the shared road itself, not individual driveways, so you'll still be responsible for your own snow removal unless a separate arrangement exists.

Can a bank deny a mortgage because a home is on a private or Class VI road?

It's possible. Financing requirements vary, and lenders may scrutinize access and road-maintenance arrangements. For private roads, that can include documentation of legal access and maintenance responsibilities. Class VI properties raise somewhat different issues, including the state's new insurability requirement, so buyers should address financing and insurance early.

Does the new legislation mean any private road property can get a building permit automatically?

Not quite. For private roads, the reforms create a clearer path in towns that adopt a policy. For Class VI roads, a separate process took effect July 1, 2026, including a recorded waiver. But local zoning requirements can still apply on top of that, so each property needs its own review.
