HB 1588 establishes a process for cities and towns to create special assessment districts to fund infrastructure improvements (like roads, water, and sewer systems) directly tied to new housing developments. Municipalities can finance these projects through property assessments on benefiting parcels - collected over up to 20 years - without using general tax revenue. The bill also expands an existing state grant program to fund municipal infrastructure upgrades for new housing, with a $1 appropriation for fiscal year 2027. This directly affects municipalities planning new housing projects and property owners within designated districts who may face assessments based on their specific benefit from improvements.
HB 1357 permits the placement of new manufactured homes on individual lots in all residentially zoned areas across New Hampshire without requiring special local permits. The bill defines "new manufactured homes" as those built after 1976 under federal safety standards and not previously placed, and requires all municipalities to update zoning ordinances to allow these homes within one year. Municipalities must apply the same general lot size and design standards to manufactured homes as to traditional homes but may set more flexible requirements, such as smaller lot sizes, for manufactured housing. This law directly affects homeowners seeking affordable housing options and municipalities responsible for zoning enforcement.
HB 1662 requires New Hampshire's Housing Finance Authority (HFA) to offer loan guarantees for accessory dwelling unit (ADU) development. The bill directs the HFA to provide guarantees covering 80-100% of a loan amount based on the completed ADU's appraised value, with an annual cap of $100 million in total guarantees. It directly affects ADU developers and homeowners seeking financing, as well as approved lenders participating in the program. The bill appropriates $25,000 for administrative costs in fiscal years 2027 and 2028, funded from the General Fund.
SB 419 expands the "housing champion" designation to include local governments that adopt zoning rules allowing child care centers near jobs (like on commercially zoned land without special permits, meeting health department standards). It allocates $5 million to the housing champion program fund and $10 million to the affordable housing fund for the 2026-2027 biennium, both non-lapsing. These funds will support affordable housing projects and local efforts to improve housing access. The bill directly affects towns and cities that change zoning to integrate childcare with commercial development.
SB 508 requires all grounds for appealing zoning board decisions to be stated in the initial appeal notice, directly affecting applicants, municipalities, and planning boards. It adds a new provision mandating that cities and towns must stamp and accept revised zoning plans within 3 business days of submission, provided the revisions address specific comments from the initial review. The bill also limits applicants to one revision round unless original comments were unaddressed, preventing repeated requests for changes beyond the initial review conditions. These changes aim to streamline the zoning approval process by setting clear timelines and revision limits. The bill applies to all municipalities in New Hampshire with zoning boards of adjustments.
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.
HB 1525 requires New Hampshire municipalities to permit at least two unrelated people per bedroom in single-family homes located within areas zoned for multi-family residential use. This change applies specifically to single-family dwellings on individual lots in multi-family zones, without altering state building or fire safety codes. The bill defines a "bedroom" as any room primarily intended for sleeping, even if used for other purposes, and clarifies that local regulations cannot override this occupancy standard. It directly affects homeowners, renters, and local governments by expanding housing flexibility in designated multi-family zones.
HB 1619 establishes new protections for property owners by prohibiting rent controls, limiting municipal zoning authority to basic health/safety needs, and requiring prompt permit processing. It repeals the InvestNH Program (which provided grants for affordable housing) and the New Hampshire Housing Champion designation. The bill prohibits government takings for private development without just compensation and bans municipal subsidies for specific housing types. These changes directly affect property owners, municipalities, and housing developers by reducing government regulation in housing markets.
HB 1625 requires New Hampshire's Office of Planning and Development to produce an annual report on accessory dwelling units (ADUs), including data on their type (attached/detached), occupancy (owner, tenant, vacant), use as short-term rentals, affordability status, and conversions from existing structures. The report must include specific metrics to help state and local governments plan for housing growth and development. The bill takes effect July 1, 2026, and does not change ADU construction rules or funding requirements. The state anticipates the reporting system will require new staff and cost between $100,000 and $500,000 annually.
This bill changes how towns regulate manufactured homes. It requires municipalities to allow siting on residential lots with the same zoning rules as single-family homes (not just in parks), and mandates "reasonable efforts" to accommodate them. Existing manufactured housing parks must follow NFPA 501A fire safety standards for expansions. It also allows disaster victims to temporarily live in manufactured homes on their property for 30 days after a building permit is issued, while rebuilding their primary residence.
