Sunnyvale has more than 1,000 Eichler homes built between 1949 and 1972, and the city's Eichler Design Guidelines call for design review of exterior changes to those homes and to other homes in mapped Eichler neighborhoods. Under those guidelines, design review also applies to floor area increases of 20 percent or more and to any second-story element, while interior improvements are not covered.
ADUs that qualify for streamlined review need only a Building Permit, while a new ADU over 800 square feet on a single-family lot first needs a Miscellaneous Plan Permit from the Planning Division.
