Overview of Accessory Dwelling Units (ADUs) in Maryland/Washington DC

Accessory Dwelling Units, or ADUs, are becoming increasingly popular in the Maryland and Washington DC areas as a creative and flexible solution to affordable housing challenges. ADUs, which are small, self-contained living units located within a larger residential property, can take many forms, including carriage houses, basement apartments, and granny flats. By creating a separate living space within their existing property, homeowners can leverage their existing property investment while providing an affordable housing option within their community. Despite some bureaucratic red tape involved in obtaining permitting and zoning approvals, more and more local jurisdictions are recognizing the potential benefits of ADUs and streamlining the regulatory process. As demand for affordable housing solutions grows, so does interest in the prospects of ADUs.

Rules Regarding ADU Placement Near Homes in Maryland/Washington DC

In Maryland and Washington DC, there are strict rules regarding the placement of accessory dwelling units (ADUs) near existing homes. This is to ensure that the new unit does not negatively impact the surrounding community. ADUs, also known as granny flats or in-law suites, are becoming increasingly popular as a way to create additional living space on an existing property. However, homeowners must follow specific rules regarding setbacks, lot coverage, and parking to be able to build an ADU on their property. It’s important to consult with local zoning ordinances and regulations to ensure that the proposed ADU placement complies with the rules and regulations set in place. For Maryland and Washington DC, ADUs can be installed in your home lot at any distance from your home, as long as it is still within your property.

By working with experienced professionals and following local regulations, property owners can ensure that their ADUs are safe, functional, and fully compliant with local zoning laws. Whether you are looking to add space to your home or create a new source of income, ADUs can be an excellent investment with long-term benefits.
