Mansfield, TX Short-Term Rentals: Occupancy Limits (2026)

Mansfield has adopted the International Property Maintenance Code which governs habitable sleeping space. Under IPMC Section 404, every bedroom occupied by one person must contain at least 70 square feet of floor area, and bedrooms for more than one occupant must provide 50 square feet per occupant. Every unit must also have at least one bathroom accessible without passing through another bedroom. Mansfield zoning additionally limits the number of unrelated adults occupying a single dwelling, typically to four under the family definition, which can constrain party-style STRs. Common STR industry practice and insurance underwriting uses a 2 per bedroom plus 2 formula meaning a 3 bedroom home hosts up to 8 guests. Hosts should set a firm maximum and include the limit in the rental agreement. Mansfield fire code requires functional smoke detectors in every sleeping room, one on each level, and carbon monoxide detectors where fuel-burning appliances are present. Exceeding IPMC occupancy can trigger habitability complaints and zoning enforcement for operating effectively as a boarding house, which is a separate, regulated use.
