Living in Hillsborough Knolls
Hillsborough Knolls is one of Hillsborough's designated neighborhoods, near the center of town. It's entirely single-family homes on large lots, with no businesses, apartments or condos. It's one of the town's smallest markets, with only about 2 to 5 sales a year, so prices vary a lot from year to year; the median rose about 66% from 2015–16 to 2024–25, well ahead of the town's 34%.
Parking & walkability: Homes have driveways and multi-car garages, and Hillsborough has no sidewalks, so this is a driving neighborhood. Downtown San Mateo and Burlingame are each a few minutes away by car, and Highway 92, 280 and 101 are all within easy reach.
