Dos Vientos is the planned community that defines Newbury Park's southern half — roughly 4,000 homes spread across hillside tracts south of the 101, with construction that began in 1992 and is still active in 2026. It's the largest single master-planned development in Thousand Oaks, built in four distinct phases by national homebuilders including Lennar, KB Home, Pulte, Toll Brothers, and Shea. The community offers modern floor plans, gated and semi-gated neighborhoods, on-site parks and schools, and direct access to the Conejo Open Space trail system. But Dos Vientos also carries mandatory Mello-Roos assessments, HOA fees, and age-based inventory issues in the oldest phases. This guide covers phase-by-phase evolution, financial obligations, schools, amenities, and what due diligence buyers and sellers need to understand to navigate this market confidently.

Dos Vientos by the numbers — 2026

Median sale price across the entire community sits around $1.55M. The range spans from approximately $1.0M for smallest townhome footprints to $3.0M+ for newer 5,500+ square-foot custom homes in the northernmost phases. Roughly 4,000 total homes have been built since 1992, spread across 25+ distinct tracts and neighborhoods. Lot sizes vary dramatically: townhome communities feature 4,000–4,500 square-foot lots, while custom hillside estates exceed 12,000 square feet. Active inventory in 2026 typically ranges from 35–55 listings at any given time. Days on market trend between 28 and 45 days for homes priced at or near market value.

The four-phase evolution — 1992 to 2026

Phase 1 (1992–1998): Lennar and KB Home built the foundation of Dos Vientos with 2,200–3,500 square-foot single-family homes on 5,000–7,000 square-foot lots. These original homes represent the most affordable entry into Dos Vientos today, with sales typically ranging $1.0M–$1.4M. Many are occupied by original owners or second-generation families. Phase 1 homes tend to show age and benefit from updates in kitchens, bathrooms, and mechanicals; condition and renovation quality vary widely. Some Phase 1 buyers today are primarily motivated by lot size, single-story layout, and lower price point to enter the community.

Phase 2 (1999–2008): Lennar, Pulte, and Toll Brothers expanded northward with 3,000–4,500 square-foot homes on larger 6,500–8,500 square-foot lots. These mid-range properties represent the growth middle class of Dos Vientos and typically command $1.2M–$1.7M. Phase 2 homes are newer enough to avoid the mechanical wear of Phase 1, but old enough to have experienced two decades of Southern California seasons. This phase includes many communities with strong HOA amenities and established landscaping, making them attractive to buyers seeking that "lived-in but not aged" sweet spot.

Phase 3 (2009–2018): Toll Brothers and Shea Homes introduced upscale tract homes with 3,800–5,500 square-foot floor plans on premium hillside and valley-view lots of 7,500–10,000+ square feet. Pricing typically ranges $1.4M–$2.1M. These homes feature modern construction standards, energy efficiency upgrades from the 2010s era, and superior architectural design. Phase 3 commands premium pricing both for newness and lot premium. However, Phase 3 and Phase 4 carry the newest and highest Mello-Roos CFD assessments, which buyers must factor into their long-term financial planning.

Phase 4 (2019–2026): Toll Brothers and Lennar are currently completing the final build-out of Dos Vientos with 4,500–6,500 square-foot custom-leaning homes on premium hillside lots. Pricing ranges $1.7M–$2.6M, with some custom homes exceeding $3.0M. Phase 4 represents the newest construction, highest energy codes, smart-home readiness, and the most restrictive HOA architectural guidelines. These homes appeal to buyers seeking turnkey new construction and the prestige of "newest phase" positioning, but they also carry the highest annual Mello-Roos assessments and HOA fees.

Mello-Roos CFD assessments — the tax that's not a tax

Every home in Dos Vientos carries a Mello-Roos Community Facilities District assessment. These are voter-approved bonded assessments used to finance infrastructure—roads, schools, parks, water, and sewage improvements—at the time of development. They appear on property tax bills as a separate line item and are senior to all other liens on the property.

Phase 1 assessments: Issued in 1992–1994, many Phase 1 bonds have already been retired or are approaching final payoff within 5–10 years. Some Phase 1 homes carry assessments as low as $400–$800 per year, while others may still owe $1,200–$1,500 annually, depending on which exact tract and bond series. Request the seller's most recent property tax statement to see the exact CFD amount.

Phase 2 and Phase 3 assessments: These typically run $1,500–$2,800 per year. Phase 2 assessments issued in the late 1990s and early 2000s still have 15–25 years of payment remaining. Phase 3 assessments (issued 2009–2012) have 25–30 years remaining.

Phase 4 assessments: The newest tracts issued in 2019–2023 carry the highest annual charges, typically $2,500–$4,500 per year, with 35–40 years of remaining bond life. A $3,500 annual Phase 4 CFD assessment adds roughly $290 per month to the effective cost of ownership—a fact that Phase 4 buyers must understand when comparing to older phases or communities without Mello-Roos.

Buyer due diligence: Always request the seller's property tax bill and CFD payoff schedule from the title company. Calculate the net present value of remaining CFD payments, especially in Phase 3 and Phase 4 homes. Some buyers choose Phase 1 homes specifically to avoid decades of CFD payments, while others accept Phase 4 CFD costs in exchange for new construction and warranty coverage.

HOA structure, fees, and architectural review

Most Dos Vientos tracts are governed by individual HOAs (each neighborhood typically has its own), rather than a single master association. This creates a fragmented landscape in which HOA fees, amenities, and rules vary significantly tract-to-tract.

HOA fee range: Dues typically run $150–$400 per month depending on phase and tract, with older Phase 1 communities at the lower end and Phase 4 gated neighborhoods at the higher end. Fees fund landscape maintenance, pool operations (where applicable), community centers, security (in gated tracts), reserve contributions, and insurance.

Architectural review: All Dos Vientos tracts enforce architectural review for exterior modifications, including paint color, fencing, landscaping, roof replacements, and additions. Phase 1 and Phase 2 HOAs tend to have more lenient design guidelines, while Phase 4 is notably restrictive. Buyers planning any exterior work should review the HOA design guidelines and budget time for approval—typically 2–4 weeks.

Reserve funding: Quality of HOA management varies. Some tracts maintain healthy reserves and fund capital projects proactively; others operate on a collection basis. Always request the HOA's current reserve study, financial statements, and list of planned assessments or special levies before closing.

Schools serving Dos Vientos

Dos Vientos is zoned to Newbury Park High School (8/10 on academic rating scale), which serves the entire southern portion of Newbury Park and some Thousand Oaks boundaries. Elementary school assignment splits between Sycamore Canyon Elementary (K–5), which is located directly within Dos Vientos, and Maple Elementary, depending on specific tract. Sycamore Canyon Elementary carries a strong reputation for arts integration, parent involvement, and academic performance, and is a primary draw for families relocating to the area.

Middle school is Sequoia Middle School (6/10 academic rating), which feeds into Newbury Park High. Newbury Park High School carries solid test scores and a college-prep curriculum, with strong athletic programs and performing arts offerings. School attendance is mandatory, not lottery-based. Families relocating from the Bay Area and Westside Los Angeles often cite school access as a secondary driver alongside new construction and master-planned amenities.

Parks, trails, and Conejo Open Space access

Dos Vientos is bookended by extensive recreational infrastructure. The Dos Vientos Community Park (47 acres) sits at the southern edge and includes a zero-entry pool, sports courts, picnic areas, and a network of trails. Sycamore Canyon Park provides additional trails and gathering spaces. The community is directly connected to the Conejo Valley Open Space trail system, which extends 2,000+ acres of oak woodland and chaparral with non-motorized trail access.

Most Phase 1 and Phase 2 homes can access major trailheads on foot (10–20 minute walk). Phase 3 and Phase 4 hillside homes often have direct trailhead access. The proximity to Conejo Open Space—unique among Thousand Oaks suburbs—is a meaningful differentiator for active families and outdoor enthusiasts. Mountain biking, hiking, and off-leash dog parks drive a segment of Dos Vientos relocations.

Retail, dining, and service proximity

The Promenade at Westlake (upscale shopping, dining, and services) sits about 5 minutes east, in Westlake Village. Janss Marketplace (regional shopping and food court) is roughly 8 minutes north in central Thousand Oaks. Newbury Park has limited commercial district activity south of the 101, so most Dos Vientos residents shop and dine via brief freeway trips to the Promenade or scattered shopping plazas in Westlake Village and Thousand Oaks proper. This is not a walkable village; it's a car-dependent suburb with convenience nearby rather than on-site.

Commute patterns and freeway access

Dos Vientos sits just south of the 101 Freeway, with multiple on-ramps (Dos Vientos Drive, Westlake Boulevard, Newbury Park Boulevard). Commutes to downtown Los Angeles average 45–60 minutes during peak hours, depending on the final destination. Commutes to the Westside (Brentwood, Santa Monica) run 35–50 minutes. The biotech cluster at Amgen (Thousand Oaks, Route 23 corridor) is roughly 15 minutes. Many Dos Vientos residents work locally or remote, reducing freeway commute dependency. Bay Area relocations often cite less gridlock and shorter regional commutes as lifestyle improvements over Silicon Valley or Peninsula traffic.

Fire safety, FAIR Plan, and insurance

Southern Newbury Park, including Dos Vientos, is classified as a high-fire-hazard zone (Wildfire Urban Interface). Insurance carriers have become increasingly selective in renewing policies; some major carriers have stopped accepting new business or raised rates substantially. New homebuyers should obtain an insurance quote early in the purchase process and factor potential rate increases into affordability calculations. Many Dos Vientos properties are insurable in the standard market, but older homes with certain roof materials or in specific tracts may face FAIR Plan placement, which costs 30–50% more than standard market rates.

Why families relocate to Dos Vientos

Relocations from the Bay Area dominate the Dos Vientos buyer base, typically driven by: new construction availability and warranty protection, modern floor plans and energy-efficient mechanical systems, master-planned community amenities and trail access, schools rated acceptably relative to Bay Area alternatives, and significantly lower entry prices than comparable Marin County or Silicon Valley markets. Westside Los Angeles relocations cite similar drivers: new construction, lot size, and escape from dense urban density without accepting rural isolation.

Military families transferring to Naval Base Ventura County (Ojai) and aerospace/defense workers at Amgen or Raytheon represent secondary but meaningful buyer cohorts. Retirees and second-home buyers from out-of-state represent a smaller segment, typically Phase 3 and Phase 4 buyers seeking California vacation property.

Buyer due-diligence checklist

For Phase 1 and Phase 2 homes: Hire a thorough pre-purchase home inspection and budget for deferred maintenance in mechanicals, roof, and structural systems. Many Phase 1 homes will need roof replacement, HVAC refresh, or plumbing updates within 3–5 years. Verify foundation integrity in Phase 1 tracts (older foundations may settle). Request HOA financial statements and reserve study.

For Phase 3 and Phase 4 homes: Verify the Mello-Roos payoff schedule and calculate the total remaining CFD cost over the life of the bond. Request warranty coverage details from the builder. Confirm builder-maintained landscaping and irrigation systems are properly installed. Review HOA architectural guidelines if planning any future modifications.

For all phases: Request the seller's property tax statement and verify the exact CFD amount. Obtain HOA CC&Rs and design guidelines. Confirm school attendance zones. Check flood insurance requirements and FEMA flood maps. Request a title report early to identify any easements, HOA liens, or special assessments not yet paid.

Seller-side positioning by phase

Phase 1 homes: Position on lot size, location within the community, and price entry point. Highlight any recent renovations (kitchen, bathroom, roof) that reduce buyer perception of age. Emphasize low or near-zero Mello-Roos remaining. Market to downsizers and first-time Dos Vientos buyers.

Phase 2 and Phase 3 homes: Lead with floor plan, finishes, and lot premium (especially Phase 3 hillside views). Emphasize modern construction relative to Phase 1. Address Mello-Roos transparently and show payoff timeline. Market to families trading Bay Area homes for equivalent Newbury Park quality at lower price.

Phase 4 homes: Leverage new construction, warranty, and energy efficiency. Position as turnkey and move-in ready. Manage expectations on Mello-Roos by calculating monthly impact and explaining long-term infrastructure benefit. Target active builders' buyer bases and warranty-conscious relocations.

Dos Vientos vs. alternatives in the Conejo Valley

Newbury Park outside Dos Vientos (north of 101, older inventory): Lower price entry ($900K–$1.3M median), no Mello-Roos, larger established lots, but homes are 30–50 years old and lack modern floor plans. Most original construction from the 1970s–1990s.

Westlake Village master-planned tracts (Westlake, Fairfield, North Ranch): Older planned communities (built 1960s–1990s), no Mello-Roos, no HOA restrictions, larger lots, golf course access, but limited new construction inventory. Median prices $1.4M–$2.2M, pricing above some Dos Vientos phases due to age and established reputation.

Big Sky in Simi Valley: Master-planned community 25 minutes north, newer construction, comparable pricing to Dos Vientos Phase 3 and Phase 4, carries Mello-Roos, HOA fees, and similar infrastructure financing. Attractive alternative if Simi Valley schools and commute patterns suit the buyer.

Moorpark and Camarillo: Lower-price alternatives ($1.0M–$1.4M median) but older inventory, less master-planning infrastructure, longer commutes to urban job centers, and less school demand.
