Does Hillsborough have a downtown?+
Hillsborough is primarily residential and does not have a conventional commercial downtown. Residents commonly use nearby Burlingame and San Mateo for shopping, dining, services, and Caltrain.
Are the areas on the map official neighborhoods?+
No. The map combines commonly used real-estate and local area names. Boundaries vary among MLS records, portals, historic subdivisions, and everyday usage, so the map is for orientation only.
Are all lots at least one-half acre?+
The Town states that a one-half-acre minimum lot-size policy has been in effect since 1953. Existing parcels and legal conditions can vary, so buyers should verify the specific parcel with the Town and title records.
Can a Hillsborough home be expanded or rebuilt?+
Possibly, but zoning standards and design review may address setbacks, height, lot coverage, massing, landscaping, grading, fencing, gates, and other exterior work. Feasibility should be checked before relying on a concept.
Why can nearby homes have very different values?+
Usable land, architecture, condition, privacy, views, street position, renovation quality, and development constraints can change the buyer pool. In Hillsborough, a citywide median is context—not a valuation method.
