Accessory Dwelling Units by Four Brothers Design + Build
Following changes to the DC Zoning Regulations in 2016, residents in most residential zones across Washington, DC are now permitted to build Accessory Dwelling Units (ADUs) on their properties. This regulatory shift has opened up a range of possibilities for homeowners looking to add living space, generate rental income, or accommodate family members.
As an experienced ADU contractor operating across Northern Virginia, Maryland, and Washington, DC, Four Brothers Design + Build has overseen the construction of multiple accessory dwelling units in a variety of styles and configurations.
Types of ADUs Four Brothers Works With
The term "ADU" covers a broad range of architectural classifications. Four Brothers Design + Build has experience working with several of these common types, including:
- Basement apartments – converting existing below-grade space into a separate living unit
- In-law suites – attached or interior units designed for extended family use
- Garage conversions – repurposing an existing garage structure into habitable space
- Detached ADUs – standalone backyard cottages or small secondary structures on the property
Each of these project types comes with its own set of design, permitting, and construction considerations. As an ADU builder with hands-on experience across multiple jurisdictions, Four Brothers Design + Build has developed a working knowledge of what to watch for during the planning phase of each build type.
Planning Considerations for ADU Projects
Through their work as an accessory dwelling unit builder in the DC metro area, Four Brothers Design + Build has identified several key factors that tend to influence how a project comes together. Zoning compliance, lot coverage limits, utility connections, and access requirements are among the practical details that need to be addressed early in the process.
Whether the goal is a granny flat, a detached backyard cottage, or a garage conversion, careful upfront planning helps avoid costly changes later in the build. Four Brothers brings that planning experience to each project they take on in the region.
For homeowners in Washington, DC, Northern Virginia, or Maryland considering an ADU on their property, Four Brothers Design + Build offers design and construction services tailored to the specific requirements of each jurisdiction and property type.
