Senate Commerce committee adopts amended SB 170 after contested hearing on housing rules and wildlife review

The Senate Commerce Committee on Oct. 27 recommended passage of Senate Bill 170 with a committee amendment that narrows several local land‑use limits while changing the bill’s effective date to July 1, 2026.

Sponsor Senator Robert Murphy summarized a multi‑part replace‑all amendment that would: prohibit local rules requiring occupants in a dwelling to be related by blood or marriage; require municipalities to use New Hampshire Department of Environmental Services (DES) test‑pit and well‑siting standards; limit municipalities’ ability to restrict dead‑end road lengths so long as the road meets State Fire Code access requirements; permit utilities and some septic/well infrastructure in open space or perimeter buffers under certain circumstances; and cap required front/side/ rear setbacks at 50 feet in some situations. Murphy said the revisions were intended to reduce regulatory obstacles that builders and developers describe as delaying housing production.

The committee heard detailed testimony and follow‑up questions at a public hearing. Mike Marchand, supervisor of the Nongame and Endangered Wildlife Program at New Hampshire Fish & Game, said his agency did not support language in the amendment that would replace existing wildlife review practice with a 5‑year lookback for recorded rare species sightings, arguing that the change would “substantially reduce our protections for species” and “basically eliminate the vast majority of our occurrences that we do reviews for.” Marchand told the committee that his agency’s current practice uses a 20‑year standard in many cases and that some species may require long timeframes to detect.

Meredith Hatfield of The Nature Conservancy echoed Fish & Game’s concerns and asked the committee to remove the proposed five‑year limit and to reconsider sections affecting wetlands and agricultural zones. She said Fish & Game and DNCR reviews are already integrated into the permitting sequence and urged caution before altering that process.

Matt Mayberry, CEO of the New Hampshire Home Builders Association, testified strongly in favor of SB 170. Mayberry described the bill as a “game changer” that would curb what he called local micromanagement, prevent repeated plan‑change demands that delay projects, and remove “outdated” familial‑status occupancy rules in some towns. He urged the committee to retain the bulk of the amendment while accepting some edits proposed by committee members.

Committee members negotiated several changes on the floor. Senators agreed to delete the proposed 5‑year limit language affecting wildlife review (lines 6–9 on page 2 of the amendment), to remove wetlands from a later provision that would have limited setback requirements, and to add a short deadline (three days) for a planning board’s initial scoping review to stamp and accept plan revisions after the first formal review. The committee also changed the bill’s effective date to July 1, 2026 to give municipalities additional time to adjust.

After the amendment was modified on the floor, the committee voted to recommend SB 170 as amended. The chair instructed OLS to place the three‑day language at the appropriate spot in the draft. The committee’s action will send the bill, with the committee amendment, to the full Senate.

The hearing transcript records that Fish & Game and The Nature Conservancy requested striking the five‑year wildlife provision and warned that revising the statutory review timing could undermine long‑term protections; the Home Builders Association urged passage to reduce planning delays and lower development costs. Several senators pressed for targeted edits instead of wholesale removal of the bill’s provisions.

The committee’s motion and subsequent voice vote indicate an affirmative recommendation to pass SB 170 with the committee amendment and the agreed edits; the amendment is recorded as 872s with the changes described above.

Looking ahead, senators agreed to leave the bill in the sponsor’s name and advance the amended version for further consideration on the Senate floor.

Votes: committee voice vote on the committee amendment and an aye voice vote for Senate Bill 170 as amended. No roll‑call vote was recorded in the transcript.
