Looking for privacy, land, and understated luxury within easy reach of San Francisco and Silicon Valley? Hillsborough checks all three boxes, but each pocket of town delivers a different feel and value story. If you are comparing Carolands, Country Club Manor, and the practical split between Lower and Upper Hillsborough, the right choice depends on how you weigh lot size, convenience, views, and budget. This guide gives you a clear, side‑by‑side understanding so you can focus your search and negotiate with confidence. Let’s dive in.
Hillsborough is an estate town by design. Since 1953 the Town has emphasized large residential lots and a rural estate character, including a long‑standing policy of a half acre minimum for most parcels. You should always confirm a specific lot’s legal status and setbacks with Town planning, but this policy sets the baseline for the town’s feel and privacy. You can read more on the Town’s history and planning context on the Town of Hillsborough site.
The market sits in the ultra‑luxury band. Recent snapshots commonly show town‑level median sale prices in the mid single‑ to low seven‑figure millions, often around $5.0 million to $5.5 million depending on the month and data window. Price per square foot regularly clears $1,000 per square foot, though product type matters a lot. Because inventory is thin, a few large estate sales can swing medians in any 12‑month period.
What drives value here is straightforward: usable land and privacy, architecture and heritage, views, proximity to private clubs, and overall scarcity. The sections below apply those drivers to the neighborhoods most luxury buyers ask about.
Carolands grew from the historic Carolands estate, anchored by the Beaux‑Arts Carolands Chateau. The chateau’s presence gives the area long‑standing prestige and a classic estate vibe. For a quick history refresher, see the Carolands Chateau overview.
You will find many parcels in the 0.5 to 1+ acre range, with a mix of mid‑century ranches, traditional homes, and larger remodels or rebuilds. Streets are leafy and quiet with generous setbacks. The feel is residential and established rather than flashy.
Most recent activity clusters in the $4 million to $7 million band for the bulk of transactions. Trophy estates exist and can trade much higher, but they are not the norm in a given year. Treat Carolands as a reliable large‑lot, mid‑to‑upper Hillsborough segment where you can secure privacy without always chasing the town’s very top tier.
As the name suggests, Country Club Manor sits by the Burlingame Country Club. This club adjacency is a defining lifestyle feature and a reason buyers target the area when golf access and green outlooks are priorities.
Parcels often run about 0.4 to 0.6 acres, with some larger estates. You will see renovated single‑story ranches alongside newer two‑story builds. Streets feel tidy and manicured, and some properties enjoy semi‑open fairway views.
Active ranges often land in the $5 million to $9 million bracket, with clear premiums for golf‑facing homes and comprehensive new construction. Inventory is thin in this pocket, so year‑to‑year availability varies.
Lower Hillsborough informally refers to the flatter, more accessible areas closest to Burlingame, El Camino, and Highway 101. Lots remain large by Peninsula standards, commonly near the Town’s half‑acre baseline, and the neighborhood pattern is suburban and convenient. Many transactions fall in the $4 million to $7 million range depending on house size and condition.
Upper Hillsborough, sometimes also described as East Hillsborough in local usage, tends to be hillier and more secluded. Select pockets feature 1 to 3 acre parcels, stronger Bay‑view potential, and a deeper estate feel. Pricing here often represents the town’s upper‑middle and top end, with many sales in the $7 million to $15 million+ range and rare trophy properties trading much higher. A single eight‑figure sale can move local averages.
“Lower” and “Upper” are practical brokerage terms rather than official boundaries. Interpretations vary slightly by map and agent, so always confirm a property’s exact location, elevation, and lot attributes when you compare comps.
Burlingame offers walkable retail districts and strong transit access. Many buyers choose it for convenience and street life, accepting smaller lots in return. Hillsborough is different by design. With no commercial district and a half‑acre baseline feel, it delivers far greater privacy, larger yards, and an estate‑oriented lifestyle. While parts of Burlingame are very expensive, town‑level medians and the ultra‑top in Hillsborough typically run higher due to lot scale and exclusivity.
For perspective on the rare top of the market, recent headlines highlighted an $88 million Hillsborough estate listing, which shows how high the town’s ceiling can reach. That kind of listing is exceptional rather than typical, but it underscores Hillsborough’s standing among the Peninsula’s elite markets. See the related coverage in SFGATE.
If you want legacy land and an established estate feel without always chasing the very top of the market, Carolands is a smart starting point. If country‑club proximity and manicured streets are non‑negotiable, Country Club Manor delivers that daily lifestyle with a corresponding premium. If you need a faster commute, Lower Hillsborough often balances lot size with convenience. If you crave maximum privacy, larger acreage, and view potential, Upper Hillsborough is where you will likely land.
The right move is to anchor your search to the feature that matters most to you, then compare like‑for‑like lots across pockets. When it is time to step in, structure your offer or listing strategy around the parcel’s land advantages and the micro‑market range you are truly competing in.
