Tiny homes on foundations in Takoma Park must meet Montgomery County building code minimum standards for habitable dwellings. There is no specific tiny home ordinance, but homes on permanent foundations may be permitted as ADUs under county zoning.

Carport Rules

Carports in Takoma Park require a Montgomery County building permit as they are classified as accessory structures.
