Overview
Independent Assessment
The Knolls is confirmed as a genuine, established, ranch-style 55+ townhome condo community with consistent multi-source agreement on its general location (Knolls Drive, off Oxhead Road), unit configuration (predominantly 2 bed/2 bath, attached one-car garage, sun-room), and clubhouse/pool/bocce/shuffleboard amenity base. A minor discrepancy in the community's opening year was found across sources (1981 per most, circa-1984 per at least one listing) and in unit count (approximately 180 per one source, though this was not independently corroborated against a recorded plat); both are reported rather than resolved to a single figure. Reported HOA fees also show an increase over time (from roughly $355/month in an October 2017 listing to approximately $455/month in more recent listings), which is treated as ordinary fee escalation rather than a conflict. Nothing in the sources reviewed independently confirmed the identity of the original developer.
Who May Find This Community Appealing
Buyers who want an established, ranch-style 55+ townhome with an attached garage and sun-room, in a quiet North Shore setting near Stony Brook University Hospital, and who value a full slate of low-key social clubs (bridge, bingo) alongside a heated pool, are a strong fit for The Knolls. Its position among the cluster of three similarly styled Stony Brook communities also suits buyers comparison-shopping within a single, familiar neighborhood.
Homes & Prices
Homes, Builders & Development History
Most sources place The Knolls' opening in 1981 (at least one listing describes a circa-1984 build), delivering ranch-style, attached townhome-style condominium units in groupings, predominantly two bedrooms and two baths with some one-bedroom and 1.5-bath layouts. Each home has an attached one-car garage, a sun-room, central air conditioning, electric heat, and a backyard patio. The identity of the original developer was not independently confirmed, and the build-year discrepancy across sources was not fully reconciled. The community is fully built out, and current purchases are resale.
Current Pricing & Market Positioning
Nearby comparable sales in the vicinity of The Knolls reported prices roughly between $300,000 and $650,000 (averaging around $420 per square foot), with one documented 2025 sale at $540,000. Buyers should request current closed comparables specific to the unit and floor plan under consideration from a local agent familiar with Stony Brook, since broader neighborhood comparables may not perfectly reflect The Knolls' own recent transaction history.
New Construction vs. Resale Considerations
The Knolls has been fully built out since the early-to-mid 1980s (sources vary between 1981 and circa-1984), so all current purchases are resale. Buyers should budget for a full independent inspection and should request the association's current financials, reserve study, and governing-document package before purchasing.

Restrictions
Age Qualification & Material Ownership Restrictions
The Knolls is marketed as an Active Adult (55+) community, consistent with the federal Housing for Older Persons Act (HOPA) framework requiring at least one resident 55 or older in at least 80% of occupied units. The community's own recorded governing-document age-restriction language or verification procedures were not independently reviewed; buyers should confirm the exact current standard directly with the HOA before purchasing.
Pros & Tradeoffs
Tradeoffs & Limitations
Sources show some inconsistency in The Knolls' exact opening year (1981 vs. circa-1984) and total unit count, so buyers should independently confirm both directly with the HOA rather than relying on any single secondary source. Reported HOA fees have apparently risen over the years (from roughly $355/month in 2017 to approximately $455/month more recently), so buyers should confirm the current figure and recent fee-increase history. The Knolls' amenities are more modest than the newer nearby Oaks community (no tennis or putting green), so buyers wanting that fuller amenity set should compare directly.
