Lewisville, TX Rental Property Rules: Repairs & Habitability (2026)

The city adopted the 2021 International Property Maintenance Code with local amendments under City Code § 9-87. 2 requires dwellings to have heating facilities capable of maintaining 68°F (20°C) in all habitable rooms, bathrooms, and toilet rooms. 3 goes further for rental housing specifically: any owner or operator who rents, leases, or lets a dwelling unit or sleeping unit, whether by express or implied terms, to furnish heat to occupants must actually supply heat maintaining that 68°F minimum, and the exception that existed in the base IPMC text was deleted by the local amendment, tightening the landlord's obligation.

4 sets a 65°F (18°C) floor for occupied indoor work spaces, with exceptions for processing/storage areas needing special temperatures and spaces used for vigorous physical activity. 14 requires every door, window, and other opening used for ventilation of habitable rooms or food areas to carry tightly fitting screens of at least 16 mesh per inch, with self-closing screen doors, unless an approved alternative like an air curtain is used. The city's neighborhood and inspection services department administers the code (a copy is kept on file with that office), and notices and orders for violations must comply with City Code § 4-245. 3.
