Flint, MI Short-Term Rentals: Occupancy Limits (2026)

Maximum occupancy of a Flint short-term rental is governed by the International Property Maintenance Code as applied through Michigan's Construction Code Act (Public Act 230 of 1972, MCL 125.1501 et seq.) and enforced via Flint's rental certification program under Public Act 247 of 2014 (MCL 125.526). IPMC Section 404.4.1 ('Room area') requires every habitable room to have at least 70 square feet of floor area. IPMC Section 404.4.2 sets minimum bedroom area at 70 sq ft for one occupant plus 50 sq ft for each additional occupant, so a 120-sq-ft bedroom legally sleeps two adults and a 170-sq-ft bedroom legally sleeps three. IPMC Section 404.5 fixes a minimum total dwelling-unit area based on total occupants. Children under 12 typically count as one-half person under IPMC Section 404.4.4, and infants under 1 year are generally not counted. Flint's housing stock includes many older single-family homes built in the auto-industry boom decades with small bedrooms by modern standards, so advertising a Flint home as 'sleeps 10' frequently violates IPMC. Inspectors with the Department of Buildings & Safety Inspections measure rooms during the rental inspection cycle and at any complaint inspection, and the Code Official has authority under IPMC Section 108 to order an overcrowded unit vacated until corrected. STR hosts should calculate the legal maximum by adding bedroom-by-bedroom occupancy and confirming the result against the IPMC dwelling-total floor.
