Should your local government change zoning laws to allow more single-family homes on smaller lots?
A September 2026 survey from St. Anselm College found that 74% of New Hampshire residents support zoning changes to permit single-family homes on smaller lots. This sentiment reflects a significant shift from 2025 as families seek more affordable housing options.
Why it matters
Lawmakers argue that current restrictive zoning, which prevents smaller lots, acts as an exclusionary barrier for young families trying to enter the housing market. By potentially lowering land requirements, proponents hope to increase the supply of accessible starter homes.
The survey of 1,293 registered voters, which carries a 2.7% margin of error, highlights that 93% of current state zoning codes prohibit single-family homes on lots smaller than 1 acre. Support for these changes has climbed steadily from 29% in 2020 to the current 74%.
The players
Ellen Read
A Democratic Representative planning to introduce legislation in 2027 to limit municipal authority over minimum lot sizes.
St. Anselm College
A private liberal arts college that conducts regular public policy and political polling in New Hampshire.
The details
Currently, the vast majority of New Hampshire communities maintain strict minimum lot size requirements that dictate land use. Legislators like Representative Ellen Read are targeting these local mandates to lower the cost of entry for homebuyers. Plans for 2027 include potential legislation that would limit municipal control over lot size and permit manufactured homes by right in all residential zones.

The Home Front
This development follows the state's decision to place Senate Bill 84 into interim study, signaling a pause in legislative progress. The trend toward relaxing exclusionary zoning reflects a broader shift in how states approach affordable housing supply versus local control.
Homeowners should monitor upcoming town planning board meetings for local discussions on density and zoning amendments following the November 2026 election. Those looking to buy or renovate should track these shifts as they may change the future land-use requirements in your neighborhood.
The takeaway
Public support for housing density has grown significantly as young families demand more affordable options. Residents should watch for upcoming 2027 state legislative sessions where new bills concerning lot sizes and manufactured homes are expected to be introduced.
