Carnassa Park

The single most important fact about Carnassa Park is the no-subdivision covenant. Decades of deed restrictions have fixed the lots at their current size, so the enclave holds a small, set number of detached homes on multi-acre parcels inside the Princeton municipal boundary. That structural cap on supply, combined with Princeton Public Schools and a quiet northeast-Princeton setting, is what defines the neighborhood and shapes what buyers are choosing between.

The homes

The housing stock reflects two eras layered on top of each other. The originals are modest mid-century houses from the late 1940s and 1950s, often well under 2,000 square feet. A meaningful share have since been taken down and replaced with significantly larger custom homes built from the late 1990s through the 2010s, with finished sizes well above 5,000 square feet. Both vintages share the same multi-acre lots and the same legal envelope, so a buyer here is typically choosing between a smaller original home priced for renovation or eventual replacement and a recently rebuilt home that has already absorbed the cost of a new structure and systems.

Streets and setting

Carnassa Park sits in the northeast section of Princeton, with homes on Littlebrook Road, Littlebrook Road North, and Random Road. The original deed restrictions trace back to the 1940s era when RCA was building out its Princeton research campus and recruiting employees into nearby housing, and those restrictions barred future splits of the parcels. The result, decades later, is a pocket of multi-acre lots inside the Princeton municipal boundary that cannot get denser, which is unusual this close to town.

Schools and commute

Every home is served by Princeton Public Schools, with the specific elementary catchment depending on street address. The location keeps the neighborhood inside the Princeton municipality, so downtown Princeton and Princeton University are a short trip away, and the setting stays residential and low-density because of the no-subdivision covenant.

Market position

The structural cap on supply is what underwrites values on the rebuilt homes, and the spread between an original house on a large lot and a fully rebuilt custom home is wide. Recorded sales show that spread directly: a 6-bedroom, 6,203-square-foot home built in 1996 at 34 Littlebrook Road sold for $2,463,000 in 2023, while a 5-bedroom, 5,124-square-foot home built in 2019 at 109 Littlebrook Road sold for $3,695,000 in November 2025. Turnover is rare, with only a handful of sales in a typical year, so pricing a home accurately against the few true comparables is where working with an agent who knows the community pays off.
