Air Conditioning Requirements in Montgomery County

Announcement Date: Sunday, June 1, 2025

As of March 2nd, 2020, Bill 24-19 "Landlords-Tenant Relations-Obligations of Landlord-Air-Conditioning" was signed into law. The law requires landlords of townhomes and multifamily rental properties to provide and maintain central air conditioning or individual air conditioning units in good working condition to protect the health and safety of tenants.

 

All rental dwelling unit air conditioning systems must have the capacity to cool habitable spaces to eighty degrees Fahrenheit (80F) or less from June 1st to September 30th. Detached single-family rental properties and rental dwellings located on a site listed in the National Register of Historic Places are excluded from the air conditioning requirement.

If your rental dwelling unit lacks functioning air conditioning, notify the landlord. If your landlord does not take action to provide functioning air conditioning within a reasonable time, you may file a complaint by calling 311 or (240) 777-0311 or online.
