Here are five tips that a residential architect should keep in mind when designing an Accessory Dwelling Unit (ADU):

​

1. Be Familiar with the Local Codes and Regulations

• Check to see how hard it is to permit a garage conversion to an ADU with proper off-site parking.

• Research and understand the specific zoning requirements, setbacks, height limits, and other regulations that apply to ADUs in the area. This includes attached and detached ADUs. They might be different.

  • Compliance with these regulations is crucial to gaining necessary permits and approvals.

 

2. Site Analysis and Integration

• Space Utilization: Carefully assess the existing property layout and available space to determine the best location for the ADU, considering factors like accessibility, privacy, and orientation.

• Complementary Design: Design the ADU to complement the main residence in terms of architectural style, materials, and landscaping, ensuring a cohesive and harmonious appearance.

​

3. Functionality and Flexibility

• Multi-Purpose Spaces: Design the ADU's interior layout to maximize space utilization and accommodate various functions, such as living, sleeping, and working areas.

• Flexible Design: Consider adaptable features like fold-down furniture or sliding partitions that allow the ADU's spaces to serve different needs over time.

 

4. Accessibility and Universal Design

• Barrier-Free Entry: Incorporate universal design principles to ensure the ADU is accessible to people of all abilities, including features like a step-free entry and wider doorways.

• Aging in Place: Design with the long-term in mind, making the ADU suitable for aging residents by considering features like grab bars, lever handles, and non-slip flooring. This could include a curbless shower or a shower with a bench and wand.

5. Utilities and Infrastructure

• Utility Connections: Plan for utility connections, including water, sewage, electricity, and gas, and ensure that the existing systems can support the additional load.

• Efficiency Considerations: Integrate energy-efficient features like insulation, energy-efficient windows, and energy-conscious appliances to reduce the ADU's environmental impact and operational costs.

• Check to see if the client prefers a shared or separate meter. Separate meter and service upgrade can be an 8 - 10 month process and should be started as soon as the client has made their decision.
