Planning board reviews zoning edits to comply with new state laws on housing and parking

The Planning Board on Wednesday discussed a set of draft zoning amendments intended to bring the town ordinance into compliance with multiple recent state law changes, including a new limit on municipal residential parking requirements and other 2025 land-use bills.

Planning staff summarized a consolidated draft of edits that would (1) modify accessory dwelling unit (ADU) parking references to follow the town's parking section, (2) change multifamily housing in Highway Commercial from a special exception to a permitted use where state law requires it, and (3) remove ordinance language that differentiates occupants by family relationship where the state law now forbids doing so.

Board members and staff said the packet was intended as a minimalist, compliance-first approach to the multiple legislative changes summarized by the New Hampshire Municipal Association.

Joseph, a staff member who presented the draft, told the board the packet included a red-line summary and a proposed single amendment that would capture most state-law changes in one place. "This is a starting point," Joseph said, adding that the draft keeps changes minimal while flagging areas that may need more policy discussion.

Why it matters: several of the state changes take effect quickly and will limit what the town can require from builders. Board members emphasized they wanted to comply with state law while reserving policy choices for later discussion at future meetings.

Most substantive points discussed

- ADU parking: The ADU section originally required an additional parking space beyond two spaces required for the single-family dwelling. Joseph said the draft replaces that fixed number with a cross-reference to the town's parking section so ADU parking will follow whatever the town's parking rules specify. The board cited S B 284 (mentioned in the staff summary) as the legislative change that reduces the maximum number of spaces a municipality may require per residential unit to 1. Board members noted the bill becomes effective immediately and said the town must ensure its ordinance references do not conflict with state law.

- Multifamily in Highway Commercial: The draft would change multifamily residential from a special exception to a permitted use in the Highway Commercial zone to conform with the state requirement for multifamily. The board discussed whether to also permit other residential types (single-family detached, two-family, townhouses) but the group generally agreed to make only the change required by statute at this stage.

- Village commercial street-level residential criteria: The draft removes special-exception language that distinguished occupants by relationship (because state law forbids such distinctions) and questioned whether remaining special-exception criteria — for example, that a facade "shall be residential in character" and that window signs be prohibited — actually accomplish the board's goals. Multiple members suggested replacing vague language like "residential in character" with a transparency/window-area requirement that would make future conversion back to commercial easier.

- Parking policy interactions: Board members and staff pointed out an interaction between the state limit of one space per unit and the town's existing clause that limits an applicant from providing more than 25% above required spaces in most zones without a special exception. Joseph said the draft flips the rule to allow residential developments to exceed the 25% cap so homeowners and smaller residential developments can provide reasonable off-street parking without repeatedly seeking zoning relief. The board discussed the transition window between the effective date of the state law and town meeting adoption of the local zoning changes.

Board direction and next steps

There was no formal vote on the substantive zoning amendments at the meeting. The board instructed staff to continue refining language and to return with examples and options on several targeted issues: (1) sample language for facade/window transparency requirements for village-commercial street-level units; (2) suggested cross-references between site plan review design standards and zoning to avoid inconsistent requirements; and (3) an analysis of the parking-cap interaction and interim implications for applications filed during the period before any local amendments are adopted at town meeting.

The board generally favored a conservative approach: make the minimum changes necessary to comply with state law now, and defer more prescriptive design or density policy choices until the board can review illustrative language and, where appropriate, public feedback.

Ending note: Staff said the packet includes a New Hampshire Municipal Association summary and a red-line draft; board members requested a follow-up packet showing specific language alternatives and examples for the next work session.
