1 New Section; Single Family Housing Acreage. Amend RSA 674 by inserting after section 16-a the following new section:
674:16-b Single Family Housing Acreage.
I. In a majority of land area that is zoned to permit single-family residential uses in a municipality, for lots not serviced by municipal or community sewer infrastructure, no ordinance shall require lot sizes for single-family residential uses larger than is required by the department of environmental services for individual sewage disposal systems pursuant to RSA 485-A and chapter Env-Wq 1000, unless the municipality provides empirical evidence that the health or safety of the community will be meaningfully impacted without the ability to require larger lot sizes. ?In determining what constitutes a majority of land area zoned for residential uses, the municipality may include areas serviced by municipal sewer infrastructure.
II. For lots serviced by municipal or community sewer infrastructure, no ordinance shall require lot sizes greater than 22,000 square feet for single-family residential uses, provided there is adequate sewage system capacity to accommodate development on such lots, unless the municipality provides empirical evidence that the health or safety of the community will be meaningfully impacted without the ability to require larger lot sizes.
III. ?The requirements in paragraphs I and II shall not be construed to limit the potential for development of lots created prior to July 1, 2025.
IV. Nothing in this section shall be construed so as to override or supersede applicable municipal zoning regulations unrelated to minimum lot sizes.
