SummerHill Reworks Hillsdale Inn Redevelopment Into 277 Homes, Leaning Into Two-Bedroom Units in San Mateo

SummerHill Apartment Communities has filed a third set of plans in nine months for the shuttered Hillsdale Inn site beside Highway 101, trimming the project to 277 homes while shifting its apartment mix away from compact urban units and three-bedrooms toward two-bedroom layouts and leaning on mechanical stackers to fit its garage.
