HB 1581 New Hampshire House · 2026 Regular Session

allowing municipalities to adopt a requirement that property owners be given notice when the assessed value of their property changes by certain amounts.

HB 1581 requires New Hampshire municipalities to mail property owners a notice within 14 days if their property's assessed value changes, unless the change is part of a town-wide revaluation. The notice must include the town hall's contact information and details on accessing assessment data online, if available. This applies to all property owners affected by individual assessment adjustments, not just those in municipal-wide revaluations. The bill has minimal fiscal impact, with estimated costs under $10,000 per municipality for printing and mailing notices.

MODERATE
The bill was fundamentally restructured from a mandatory requirement for all municipalities to send property assessment change notices into an optional program that municipalities may choose to adopt by vote. A $1,000 minimum change threshold and a full-revaluation-year exception were added, along with detailed ballot and voting procedures for adoption and annual rescission. The fiscal note was changed from an estimated cost to 'no fiscal impact' since the requirement is now opt-in.
SCOPE

The bill changed from mandating that ALL municipalities must send assessment change notices to allowing municipalities to optionally vote to adopt the requirement. This shifts the burden from every municipality to only those that choose to participate.

REQUIREMENT

A $1,000 minimum threshold was added: notice is only required when a property's assessed value changes by more than $1,000, meaning small adjustments no longer trigger a notice obligation.

New procedures were added for how municipalities adopt the option: by majority vote of the legislative body, or via official ballot at annual town meeting with specific ballot language provided. Cities and towns without town meetings use a legislative body majority vote.

ELIGIBILITY

An exception was added for years in which a full municipality-wide revaluation is conducted, during which the notice requirement does not apply.

ENFORCEMENT

If a municipality adopts the option, an annual question to rescind it must be placed on the official ballot at town meeting, giving residents ongoing control over whether the requirement continues.

FISCAL

The fiscal note changed from estimating an indeterminable increase of less than $10,000 per municipality in staff time, printing, and mailing costs to stating there is no fiscal impact, reflecting that the obligation is now optional rather than universal.
