Relating to a landlord's duty to provide and maintain a functioning air conditioning system or unit in an apartment.

HB 1099 would require landlords in Texas to provide and maintain a working air conditioning system in apartment units that keeps indoor temperatures at or below 85°F, or 10°F below the outdoor temperature - whichever is lower. The bill explicitly states landlords cannot waive this duty, and it adds failure to provide functional AC to the list of conditions landlords must repair under tenant rights laws. This directly affects all residential landlords renting apartments and their tenants, particularly in hot weather. Tenants could then pursue remedies under existing property code provisions if AC isn’t maintained, similar to other health/safety issues like lack of hot water.
