HB 60 (2025)
After six months of renting, this bill adds the expiration of the term of the lease or tenancy as grounds for an eviction.
The Senate amended the bill so that it will only take effect if there is a 4% vacancy rate in the state. The amended bill also increases in the minimum lease term to twelve months before eviction.

The Senate added some of this bill to HB 710.
SB 284 (2025)
Limits zoning laws to require no more than one parking spaces per residential unit, with exceptions for certain workforce housing and multi-family developments.

SB 295 (2025)
Removes the household income limit to participate in the Education Freedom Account (EFA) program.

SB 62 (2025)
Prohibits state and local government from blocking law enforcement participation in a federal 287(g) program. That program allows local law enforcement to perform some immigration enforcement duties.

Should NH add an income tax on earned income?
Against an income and/or sales tax. On a property tax cap: "The 'some formula' that I have seen discussed is to base the cap on income. Capping property tax for lower income taxpayers would necessarily shift the burden to the upper income levels. This would, in effect, turn the property tax into an income tax. I am opposed to the income tax."
