Hillsboro homeowners can build an Accessory Dwelling Unit up to 800 square feet or 75% of the primary dwelling living area, whichever is smaller, according to Hillsboro Planning Department regulations. ADU Construction in Hillsboro follows these exact local guidelines. The maximum size applies to the interior habitable space, not including garages or unheated storage. Hillsboro ADU builders also must follow specific height restrictions, typically limiting Accessory Dwelling Units to one story or a maximum of 25 feet if two stories, depending on the zoning district. Understanding these limits early in the design phase is very important for a compliant and approvable project.
Hillsboro homeowners are generally not required to build separate utility connections for an ADU. An Accessory Dwelling Unit can share utility services with the primary dwelling. The ADU can connect to the existing water, sewer, and electrical services of the main house. Sharing these services will reduce infrastructure costs for the project. Property owners often install separate sub-meters for electricity and water inside the ADU. These sub-meters allow for easier tracking of utility usage and tenant billing. Our ADU contracting team always verifies specific utility requirements with the City of Hillsboro during the planning phase.
