Summerset

Independent Assessment

Summerset is strongly confirmed as a genuine, large-scale 55+ golf community, with multi-source agreement on its four-phase build-out (I: 471 homes/1994, Palms II: 431 homes/1998, Vista III: 464 homes/2000, Orchards IV: 647 homes/2002-2005 by Del Webb) totaling approximately 2,013 homes on 1,000 acres. The direct citation of California Civil Code Section 51.3(b)(4) in Summerset IV's own publicly available recorded CC&R document is an unusually strong, primary-source legal confirmation of age-restricted status. Because Summerset is organized as four separate HOAs rather than a single master association, reported HOA fees and specific amenity details should be treated as varying meaningfully phase by phase rather than as a single uniform figure; buyers should confirm the specific phase's current fees, CC&Rs, and amenity access directly with that phase's HOA.

Who May Find This Community Appealing

Buyers who want a large, established, golf-centered 55+ community with genuine legal confirmation of its senior-housing status, and who are comfortable navigating a multi-phase structure where each of four HOAs has its own clubhouse and fee schedule, are a strong fit for Summerset. Its Brentwood setting, with an on-site 18-hole golf course and 1,000-acre footprint, also suits buyers who want a more resort-scale, golf-oriented lifestyle within the same eastern Contra Costa County corridor as Trilogy at the Vineyards and Barcelona, but built out over a longer, more incremental timeline by multiple builders including Del Webb.

Homes, Builders & Development History

Summerset was developed in four sequential phases over roughly eleven years on a 1,000-acre site in Brentwood. Summerset I broke ground in 1994 and ultimately included 471 homes. Summerset Palms (Summerset II) followed beginning in 1998 with 431 homes. Summerset Vista (Summerset III) began in 2000 with 464 homes. The final phase, Summerset Orchards (Summerset IV), was built by Del Webb between 2002 and 2005 and added 647 homes, bringing the community's combined total to approximately 2,013 residences. All four phases are now fully built out, and current purchases across the community are resale.

Current Pricing & Market Positioning

A single, current, community-wide price range covering all four Summerset phases was not found. Given the community's eleven-year, multi-builder build-out (1994-2005) and its shared 18-hole golf course and 1,000-acre amenity base, pricing is likely to vary meaningfully by phase, home vintage, and lot/view premium; buyers should request current comparables specific to the target phase (I, Palms II, Vista III, or Orchards IV) from a local agent familiar with the Brentwood resale market.

New Construction vs. Resale Considerations

All four Summerset phases are fully built out (the most recent, Summerset Orchards/IV, completed by Del Webb in 2005), so current purchases across the community are resale. Given the range of construction dates (1994-2005), buyers should budget for a full independent inspection reflecting the specific phase's age and should request that phase HOA's current financials, reserve study, and CC&R documentation before purchasing.

Taxes, Insurance & Special Assessments

Homes across all four Summerset phases are subject to Contra Costa County property tax at the county's current rate. California's Proposition 19 allows qualifying homeowners 55 or older to transfer their existing assessed property value to a replacement home, separate from this community's own 55+ age-qualification threshold; buyers should confirm current eligibility and exact rates directly with the Contra Costa County Assessor's Office.

Golf

Summerset includes its own 18-hole golf course, with direct access reported across all four phases of the community, making it one of the more golf-centered 55+ communities in the eastern Contra Costa County/Brentwood cluster. Current green fees, membership structure, and whether the course is HOA-owned or separately operated have not been independently confirmed; golf-focused buyers should confirm current terms directly with the relevant Summerset phase HOA.

Community Layout & Lifestyle

Summerset offers a large-scale, golf-centered 55+ lifestyle spread across 1,000 acres and four sequentially built phases, each with its own clubhouse, pool, and fitness facilities, while all residents share access to the community's 18-hole golf course and extensive trail network. The phased, multi-builder development (culminating in Del Webb's Summerset Orchards) gives buyers a range of home vintages and price points within a single well-established, golf-oriented East Bay community, distinct from the resort-style, single-phase design of nearby Trilogy at the Vineyards.

Shopping, Healthcare & Airport Access

Summerset is located in Brentwood, in eastern Contra Costa County, California, roughly 30 miles east of San Francisco. The community's four phases sit within the broader Brentwood residential and golf corridor, with access to State Route 4 for commuting within the East Bay and the greater Bay Area.

Age Qualification & Material Ownership Restrictions

Summerset's recorded CC&Rs (confirmed for the Summerset at Brentwood IV Association) explicitly define the community as a "senior citizen housing development" under Section 51.3(b)(4) of the California Civil Code — the specific statutory provision within the Unruh Civil Rights Act governing senior housing developments' occupancy restrictions. This is a direct, primary-source legal confirmation of the community's age-restricted status. California's Unruh Act generally requires a 100%-occupied-unit standard, stricter than the federal HOPA 80% minimum. Buyers should confirm the current exact age-restriction percentage, minimum occupant age, and any caregiver or additional-occupant exceptions directly with the specific phase HOA relevant to the home under consideration, since each of the four Summerset associations maintains its own CC&R document.

Tradeoffs & Limitations

Because Summerset comprises four separately governed HOAs rather than a single association, buyers must confirm which specific phase (I, Palms II, Vista III, or Orchards IV) a given home belongs to, since fees, clubhouse access, and CC&R specifics can differ by phase even though all share the community's golf course and overall Summerset identity. Given the range of construction dates (1994 to 2005), buyers should expect meaningfully different home vintages, finishes, and renovation histories depending on the phase, and should budget for a full independent inspection on any resale purchase. A single current price range or HOA fee figure applicable across all four phases could not be confirmed; buyers should request phase-specific figures directly from the relevant HOA or a local agent.

Comparison With Nearby Communities

Within Brentwood's eastern Contra Costa County 55+ cluster, Summerset is considerably larger in scale (approximately 2,013 homes across four phases) than Shea Homes' single-phase Trilogy at the Vineyards (roughly 1,100 homes) or its smaller Barcelona enclave (72 homes), and is the only one of the three built out by multiple builders over more than a decade, including a Del Webb-built final phase. Unlike Trilogy at the Vineyards, which relies on an adjacent, separately owned golf club, Summerset includes its own 18-hole course with direct resident access across all four phases.

Is Summerset one community or four separate ones?

Summerset was built as four sequential, separately governed phases — Summerset I, Palms/II, Vista/III, and Orchards/IV — each with its own HOA, clubhouse, and CC&Rs, though all share the community's identity, golf course, and general amenities.

Is Summerset legally age-restricted?

Yes. Summerset's own recorded CC&Rs (confirmed for the Summerset IV Association) explicitly define it as a senior citizen housing development under California Civil Code Section 51.3(b)(4), the Unruh Act's senior-housing exemption.

Does Summerset have its own golf course?

Yes — Summerset includes its own 18-hole golf course with reported direct access across all four phases, distinguishing it from some nearby 55+ communities that rely on an adjacent, independently owned course.

Who built Summerset, and when?

Summerset was built by multiple builders across four phases from 1994 to 2005: Summerset I (1994, 471 homes), Palms/II (1998, 431 homes), Vista/III (2000, 464 homes), and Orchards/IV (2002-2005, 647 homes, built by Del Webb).
