Campbell homeowners can typically build an ADU up to 1,200 square feet for a detached unit, or 50% of the existing primary dwelling's living area for an attached unit, not exceeding 1,200 square feet. The specific maximum size depends on your lot size and the existing primary dwelling's footprint, with a minimum size of 150 square feet. We always verify the exact allowable dimensions based on your property's zoning and specific parcel characteristics during the initial design phase. This ensures your ADU design is compliant from the outset, preventing issues during plan check.
The ADU permitting process in Campbell typically takes 3 to 6 months from initial submission to permit issuance, assuming a complete and compliant plan set. This timeline includes plan check reviews by the City of Campbell's planning and building departments, as well as any necessary revisions. Factors like the complexity of the design, the completeness of the initial submission, and the current volume of applications at the city can influence this duration. We prepare detailed plans and documentation to streamline this process, which helps minimize review cycles.
An ADU in Campbell requires independent utility connections for water, sewer, and electricity, or shared connections with the primary dwelling if approved by the utility provider and city. For sewer, a separate lateral connection to the main line or an adequate connection to the existing primary dwelling's sewer line is typically required, often necessitating an upgrade to the main line capacity. Electrical service usually involves extending power from the main panel or installing a new sub-panel, depending on load calculations. Water connections often involve a separate meter or a sub-meter, which means coordinating with San Jose Water Company. We handle all utility coordination and trenching, ensuring all connections meet current codes and capacity demands.
