When planning your new ADU, there are several important site preparation, design, and construction considerations we bear in mind.
Your accessory dwelling unit needs to fit in with the style and look of the surrounding property and neighborhood.
This depends on whether you plan to rent your ADU or use it as a family annex. If renting in Bay Area, some tenants may require certain levels of privacy
Before making any designs, we consider how you want to use your dwelling unit and ensure enough space. If it is too small, the unit could feel restrictive, while if it is too big, it may fall foul of Bay Area ADU construction laws.
Ensuring all units have an open route to the street for accessibility and safety reasons. If you have tenants, it’s important to consider more private access routes that bypass your main home area and other accessibility features such as wheelchair ramps and handrails.
Depending on your location, Bay Area ADU construction regulations and local zoning laws will guide us through the structural design of your unit.
We take site analysis and preparation seriously to get the right type of foundation and structural quality for your unit.
Our ADUs are more spacious by considering brilliant views, windows/doors, and outdoor spaces for better living.
Choosing the right contractor is critical for a successful ADU project. As experienced Hillsborough ADU contractors, we bring hands-on construction expertise, strong project management, and local regulatory knowledge to every build.

In Hillsborough, homeowners can typically build one ADU per single-family lot. ADUs are allowed on properties with a primary single-family home, and in some multi-family zones, additional ADUs may be permitted based on local regulations.
Hillsborough allows ADUs up to 800 square feet for most single-family lots. Larger lots may support ADUs with more living space or additional bedrooms, depending on zoning and lot size. Converted ADUs within an existing home are generally limited to 25% of the main structure’s size.
Detached ADUs in Hillsborough must follow standard property setbacks, typically 4 feet from side and rear property lines. When built above a garage, the same minimum setbacks apply, and placement must ensure proper access and fire safety clearances.
Detached ADUs may reach up to 16 feet in height, while those built above a garage can go up to 24 feet, or match the height of the main house if it is taller. Height limits may vary based on zoning and roof design.
Hillsborough has specific planning considerations that directly impact ADU construction, including zoning regulations, lot coverage limits, and architectural review standards. Our local expertise allows us to anticipate challenges related to approvals, utilities, and inspections.
