Rental registration and inspection
Hartford requires a four-year Rental License for each building with three or more units, except owner-occupied three-families, and the Fire Marshal inspects licensed buildings every year of the term.
For investors: The license replaces the $25-per-unit Certificate of Apartment Occupancy for units in the building, and its fee covers only the first housing and fire code inspections. Buildings with five or more housing code violations can be pulled into the program ahead of schedule.

Non-owner-occupied Hartford three-unit buildings, the program's final phase, must apply between July 1 and October 31, 2026, at $60 plus $50 per unit; a late application adds a $1,000 penalty.
For investors: A non-owner-occupied three-family bought this fall still has to be licensed by October 31, 2026, or the $1,000 late penalty applies, and renting unlicensed can bring daily per-unit fines. Four- to nine-unit buildings had their 2025 window, so ask the seller for that license.
