A provision in New Hampshire's dam-funding bill imposes a new recurring fee on waterfront small businesses—and most owners don't know it's coming.
Most New Hampshire property owners and managers haven't heard of HB1655, the bill establishing a funding source for maintaining state-owned dams. But buried in that legislation is a provision that will create a new annual monetary obligation for any small business owning waterfront real estate near a state dam—starting in 2026.
Under Section 1 of RSA 77:22(II), municipalities must annually assess a fee on qualifying waterfront property:
This is not a one-time charge. It recurs annually and is enforceable like other property tax obligations. If the fee goes unpaid, the state can impose 8% annual interest and place a tax lien on the property—the same enforcement mechanism used for property taxes.
The fee applies to small businesses owning real estate that meets two criteria:
This includes marinas, boat launches, waterfront restaurants, lodges, rental properties, and other commercial operations. Residential property owners and larger commercial entities may be treated differently under the statute, but any small business in the affected zone should verify its status with its municipality.
The provision becomes effective July 1, 2026. However, the Department of Revenue Administration (DRA) estimates that actual collection will not begin until spring 2028—giving municipalities time to identify qualifying properties and establish assessment procedures.
Property owners should not assume they have until 2028 to prepare. Municipalities may begin notifying affected owners well before collection starts, and the fee will likely be retroactive to the effective date once billing begins.
If your small business owns waterfront property near a state dam, you should:
For businesses operating on thin margins or managing multiple waterfront properties, this new fee represents a material change in operating costs. Early awareness allows you to factor it into budgets and pricing before bills arrive.
