HB 1540 New Hampshire House · 2026 Regular Session

relative to municipal health ordinances and accessory dwelling units and relative to on-premises licenses for licensed barbershops and salons.

HB 1540 establishes statewide rules for accessory dwelling units (ADUs), allowing one ADU per single-family home as a matter of right in most zoning districts without extra lot size or design requirements beyond those for the main home. In protected shoreland areas, municipalities may permit ADUs as a matter of right or through conditional permits, and they can choose to allow detached units if they meet specific environmental and zoning standards. The bill prohibits multiple ADUs per home, ADUs in townhouses (attached multi-family properties), ADUs on rented land, and separate sales of ADUs from the main house without municipal approval. It provides municipalities with clear guidance for zoning, permitting, and environmental protections related to ADUs while standardizing requirements across the state.

As Amended by the House As Amended by the Senate · 6 edits
MODERATE
The Senate significantly expanded the bill's scope by adding an entirely new section creating a two-tier alcohol licensing system for barbershops and salons, allowing them to serve or sell one drink per customer per appointment. The original House version only addressed municipal authority over septic systems related to accessory dwelling units. The Senate also split the effective date so the ADU provisions take effect July 1, 2026, while the new barbershop/salon licensing takes effect 60 days after passage.
Scope change
The bill expanded from a single-topic measure on municipal septic authority for accessory dwelling units to a two-part bill that also creates a new alcohol licensing framework for barbershops and salons, fundamentally broadening its subject matter.
SCOPE

A new Section 2 was added amending RSA 178:21, III to allow licensed barbershops and salons to obtain on-premises alcohol licenses in two tiers.

ELIGIBILITY

Tier 1 license allows serving one free drink per customer per appointment (16-oz beverage, 6-oz wine, or 1.5 oz liquor) for a $100 fee. Tier 2 license allows selling one drink per customer per appointment at the same size limits for a $480 fee.

Salons or barbershops located within a private residence are explicitly prohibited from receiving a license under this section.

REQUIREMENT

Licensees must keep records of patrons served (Tier 1) or beverages sold (Tier 2), make those records available to the commission, complete a management training seminar, and ensure sales are incidental to barbering/cosmetology services rather than a standalone bar operation.

ENFORCEMENT

The liquor commission must submit an annual report to the speaker of the house and president of the senate by November 1 each year listing licenses applied for, granted, denied, inspections performed, and total violations.

TIMELINE

The effective date was split: Section 1 (ADU/septic provisions) still takes effect July 1, 2026, but the new barbershop/salon licensing section takes effect 60 days after passage instead of a fixed date.
