Rental registration and inspection
Rochester requires a renewable Certificate of Occupancy, issued after inspection, for buildings with rental units; owners living in their own one- or two-family home are exempt, with narrower relief inside the Lead High-Risk Area.
For investors: A home lived in by the owner's spouse, parent, child or sibling can claim an exemption that is renewed every three years. Since 2026, a pre-1980 owner-occupied double inside the high-risk boundary still needs a certificate, with only the owner's own unit spared from inspection.

Rochester's code, amended in June 2026, sets Certificate of Occupancy fees per building at $150 for a single-family, $250 for a two-family and $350 for three to five units, doubled when renewal is late.
For investors: The fee is per building, so a lot with a front house and a rear cottage pays twice. It doubles if the renewal application arrives more than 40 days after the city's notice, or if title transfers without a required certificate.
