relative to zoning procedures concerning residential housing.

SB 84 sets maximum lot sizes for single-family homes based on water and sewage infrastructure availability. For lots without municipal sewer, the cap is 66,000 square feet; with municipal water, 44,000 square feet; and with municipal sewage, 22,000 square feet. Municipalities must provide empirical evidence if they seek to exceed these limits due to infrastructure capacity concerns. The bill directly affects local zoning regulations in New Hampshire municipalities with single-family residential zoning.
