On August 21, 2025, Governor Kelly Ayotte, Mayor Jay Ruais, and legislators, housing advocates, and builders celebrated new laws to tackle the housing crisis during a ceremonial bill signing at NeighborWorks in Manchester.
“Tackling our housing crisis is critical to keeping New Hampshire the best state in the nation for economic opportunity,” said Governor Ayotte. “From streamlining our state permitting process, to cutting unnecessary red tape, to expanding opportunities for new housing construction, and more, we made important strides this year. I thank the legislators, advocates, and private sector partners who worked to bring these bills to my desk, and I look forward to continuing to work together to bring more housing to our state for our young people, our seniors, and for all of New Hampshire.”
