Rental registration and inspection
New Haven's Residential Rental Business License, run by the Livable City Initiative, covers non-owner-occupied two- and three-family homes and buildings of four or more units; single-family rentals and owner-occupied two- and three-families are exempt.
For investors: A house hack in a two- or three-family stays exempt while the owner lives there, but the license applies once the owner moves out. Condominiums and buildings where every tenant holds a Housing Authority of New Haven voucher are also exempt.

New Haven's licensing page lists fees of $225 for the first two units and $60 per additional unit, from the fee schedule the Board of Alders approved for fiscal 2022-23.
For investors: Under that schedule a three-family costs $285 and a six-unit building $465. City code ties the fee to the annual budget, so confirm the current amount with the Livable City Initiative before closing, along with any second re-inspection or missed-appointment fees.
