Tiny House Regulations Maryland

Montgomery County Md Zoning Ordinance Text

Montgomery County, Maryland :  Now updated their county zoning ordinances to allow Tiny Houses and Accessory Dwelling Units with the exception of Silver Springs and Bethesda.  The Ordinance goes into effect December 2019.

  • Tiny house regulations and codes may vary by city, town, or county.
  • Tiny houses are not yet acknowledged by the state.
  • Laws are more friendly toward tiny houses on foundations, rather than tiny houses on wheels.
  • Tiny houses on wheels fall into the category of RV, but the only place they can be parked legally is in a dedicated RV park. Most RV parks have restrictions on length of occupancy.

While the demand is certainly there, some counties and cities in Maryland have zoning laws in place that greatly restrict people from living in tiny houses. The more rural a tiny homeowner is willing to go, the more likely they will be able to find a place to park or build a tiny house.


This state has not officially defined what tiny houses are or created statewide requirements and restrictions. Generally, laws at the city level classify tiny houses on wheels as recreational vehicles. Because of this, they can only be placed in a designated RV park in most areas. The specific restrictions, such as those related to dimensions and occupancy, are usually established by the RV parks. In many areas, tiny houses on foundations are acceptable, but zoning restrictions in urban and suburban areas may not be conducive. Because of this, many tiny homes in Maryland are found in rural areas that have fewer restrictions.
