Creating a public county registry of the monthly rent charged by landlords for each owned unit and prohibiting landlords from using algorithms or software to determine rental rates.

In one paragraph

New Hampshire's HB 558 would create a public county registry of monthly rents kept by registers of deeds, require landlords to file rent lists and a notarized affidavit that they used no algorithm or software to set rents, and prohibit landlords from using any algorithm or software to determine rental rates. The House Housing Committee recommended Inexpedient to Legislate (10-8) and the House adopted that on March 20, 2025, so the bill did not pass.

What it means for business

None: the bill did not pass. It would have barred New Hampshire landlords from using any algorithm or software to set rents and required annual rent filings.

Key provisions

  1. New RSA 478:17-k: each register of deeds would keep a public registry of the monthly rent and specifications (square footage, bedrooms, bathrooms, location, amenities) of leased properties in the county
  2. Landlords owning property in the county would have to submit the list to the register of deeds annually by December 31, with a signed, notarized affidavit that they used no algorithm or software to determine the rent
  3. A landlord who changes the rent would have 30 days to notify the register of deeds
  4. New RSA 540-A:3, X: no landlord could use any algorithm or software to determine the rent for any rental unit
  5. As introduced the act would take effect 60 days after passage; the fiscal note says counties would face an indeterminable cost increase
