Oak Park is an unincorporated community of Ventura County, and it was built out as a sequence of tracts from the late 1960s to the early 2000s under the county’s planning. Metropolitan Development Corporation bought the ranch land in the 1960s and the first houses went up on the valley floor in the late 1960s; the Municipal Advisory Council formed in 1975 and persuaded the county to cut the planned build-out from 26,000 residents to about 15,000, and the community seceded from Simi Valley Unified to form its own school district in 1977. The tracts of the 1980s and 1990s filled the slopes on either side of Kanan Road, and the last of them, above Deerhill Road, were finished in 2002.

Chaparral Estates is where the community began. The recorded sales are built from 1968 to 1979, the earliest houses in Oak Park, on the flat ground east of Kanan Road along Medea Creek; the MLS files the sales as Chaparral Estates and, for the older phases, simply as Oak Park. The county records show about 530 parcels inside the outline, which makes it the largest tract in the community. Secondary sources date it to the late 1970s and early 1980s and describe individually styled houses rather than repeated plans; the developer is not named in any source Gary Jacobs has been able to verify.

The record runs from a 1,680-square-foot three-bedroom to a 2,781-square-foot five-bedroom, median 2,212, and it is the most varied in Oak Park: single-story ranches, two-story houses and split levels from a decade of building. The top is $1,753,000 on Smoke Tree Avenue in June 2026 for a 2,399-square-foot five-bedroom on a 25,700-square-foot lot, $1,602,000 on Pinion Street in June 2025 for a 2,240-square-foot four-bedroom, and $1,599,000 on Maplegrove Street in March 2025 for a 1,996-square-foot single-story five-bedroom. The bottom is $757,000 on North Park View Drive in April 2020 for a 1,689-square-foot single story and $775,000 on Smoke Tree Avenue in June 2020. Twelve of the thirty sales are four-bedrooms, nine are three-bedrooms and nine are five-bedrooms; fifteen are single story, at a median of $1,185,000.

No plan sheet for Chaparral Estates is in the Conejo Simi Moorpark Association of Realtors archive that this guide series draws on, so there is no drawing to reproduce. The sale record shows homes of 1,680 to 2,781 square feet, median 2,212, with four bedrooms in twelve of the 30, three in nine, five in nine, and fifteen of the 30 recorded sales are single story.

Smoke Tree Avenue is the spine, with ten of the thirty sales, and the tree-named streets run off it: Maplegrove, Bayberry, Tamarind, Pinion, Joshua and Buttonwood, with Park View Drive along Oak Canyon Community Park. The lots run about 6,500 to 25,700 square feet, median about 7,800, and the largest are the creek-side and corner lots. This is the flattest ground in Oak Park, and the streets are the ones that walk to Brookside Elementary, the park and the Medea Creek trail.

The first reason is the single story: half the record, the largest supply of one-level houses in Oak Park. The second is the absence of a fee and of an architectural committee, which matters to an owner who wants to add on or build an accessory unit on a 7,800-square-foot lot. The third is the ground, flat and walkable to the elementary school, the park and the trail. The fourth is the variety: no two houses are the same, and a buyer who does not want a production tract has one here.

No association fee appears in any of the thirty recorded sales, and two secondary sources agree that Chaparral Estates has no homeowners association.

No association fee appears in the recorded sales, which means the constraint on an owner is the city and county permit process rather than an architectural committee. Confirm with the title report that no association or CC&Rs attach to the specific parcel.

Oak Park is its own school district, Oak Park Unified, a small independent K–12 district formed in 1977 and one of the main reasons buyers choose the community. The district publishes an elementary boundary street list, and every street in this tract’s sale record — Smoke Tree Avenue, Maplegrove Street, Bayberry Street, Tamarind Street, Pinion Street, Joshua Street, Buttonwood Avenue, Peregrine Circle, Woodcrest Place and Park View Drive — is assigned to Brookside Elementary. The district has one middle school, Medea Creek, and one high school, Oak Park High, so there is no boundary question above fifth grade. The street list this guide relies on is dated 2017; confirm the current assignment with the district office before relying on it.

Brookside Elementary, Oak Canyon Community Park with the duck pond and the splash pad, and the Medea Creek trail are inside or beside the tract, and the Oak Park Plaza is at the bottom of Kanan Road. Oak Park runs on its parks, its trails and its one shopping center: the Oak Park Plaza at Kanan Road and Lindero Canyon Road for the supermarket, the pharmacy and the everyday errands, Oak Canyon Community Park with the duck pond and the splash pad, Deerhill Park and Medea Creek Park for youth sports, the Medea Creek trail down the middle of the community, and the Palo Comado and Cheeseboro trailheads into the Santa Monica Mountains National Recreation Area. Everything else is in Agoura Hills or Westlake Village, five to ten minutes away, and the Ventura Freeway is reached down Kanan Road to the Kanan interchange or down Lindero Canyon Road to the Lindero interchange.

Oak Park has no freeway of its own. Kanan Road runs south to the Ventura Freeway at Agoura Hills in about eight to twelve minutes from most streets, and Lindero Canyon Road runs south to the Lindero Canyon interchange in Westlake Village; the north-side tracts add a few minutes to either. Errands are at the Oak Park Plaza on Kanan Road or in Agoura Hills and Westlake Village; the Westside is forty-five minutes on a good day and ninety on a bad one, and a buyer who commutes should time it at 7:30 in the morning before deciding.

The figures in this section were current when this guide was last reviewed. The sale record in the facts above and the listings below are drawn live from the MLS each time the page loads.

In the two years through September 2026, 20 homes in the tract sold through the MLS, at prices from $1,025,000 to $1,753,000 and a median of $1,255,000. Over the longer record since April 2020, 30 sales ran from $757,000 to $1,753,000 with a median of $1,250,000. The top of the record is $1,753,000 on Smoke Tree Avenue in June 2026 for a 2,399-square-foot five-bedroom; $1,602,000 on Pinion Street in June 2025 for a 2,240-square-foot four-bedroom; $1,599,000 on Maplegrove Street in March 2025 for a 1,996-square-foot five-bedroom. The bottom is $757,000 on N Park View Drive in April 2020; $775,000 on Smoke Tree Avenue in June 2020; $928,430 on Smoke Tree Avenue in October 2020. Single-story homes account for fifteen of the 30 sales, at a median of $1,185,000.

Thirty sales in six years from $757,000 to $1,753,000 is a wide band because the houses are so different from one another: a 1,689-square-foot single story on a 6,500-square-foot lot and a five-bedroom on a 25,700-square-foot lot are both Chaparral Estates. What the record shows is $750,000 to $950,000 in 2020 for the smaller houses, and a band from $1,150,000 to $1,750,000 since 2024 with the renovation and the lot deciding the place in it. The single-story houses, half the record, trade at a median of $1,185,000 against $1,250,000 for the whole. Gary Jacobs keeps the full sale-by-sale history and can say where a given house sits in it.

No lease is recorded in the MLS sources this guide draws on, so it does not quote a rent for Chaparral Estates; a current figure should come from the leasing agents who work these streets. A detached house in this district at this size is a scarce rental, and the tenants it draws are families relocating for the schools who want a year or two to buy.

These homes date from 1968 to 1979, and the inspection carries the late-1960s list: original galvanised supply lines, original electrical panels of brands insurers now flag, single-pane aluminum windows where not replaced, original furnaces and ductwork, and roofs and sewer laterals at or past end of life. Slope lots add drainage and retaining-wall questions that a general inspector will flag but a geotechnical engineer should answer; pools of this age often have original equipment and plaster. None of this is unusual; all of it is negotiable if it is found before the contingency comes off rather than after.

In a tract of this era the remodels that return their cost are the ones that bring a 1960s plan to the way people live now: the kitchen opened to the family room, the primary bath and closet, the floors and the glass, and, on the right lot, the pool. What does not return its cost is the addition that pushes the house past what the street will support; the record shows the top sales are renovated versions of the original plans on the better lots, not the biggest houses.

The comparison is the tracts around it. Country Glen, 1986 to 1987, is 1,348- to 2,925-square-foot houses on the slopes above at a median of $1,075,000 with a fee near $175 a month. Ridgefield, 1986 to 1987, is 1,840- to 2,459-square-foot houses at a median of $1,250,000 with a fee near $200. Morrison Estates and Sutton Valley, 1986 to 1989 on the north side, is the step up, at a median of $2,000,000 on quarter-acre lots. Chaparral Estates is older than all of them, has no fee, has the single stories, and sits on the flattest, most walkable ground in the community.

Start with the house, because it is fifty years old: the inspector briefed for the late 1960s and 1970s, the sewer lateral scoped, the panel and the plumbing named, and the permit history of every addition pulled from the county, since these houses have been added to for five decades. Then the lot, the creek side and the drainage. Then the title report, to confirm that no association or CC&Rs attach to the parcel. A buyer who wants a house that needs nothing should look at Chambord or Regency Hills instead.

Families first, for Brookside, the park and the flat streets. Buyers who want a single story second. Buyers who want to build third, an addition or an accessory unit, for the lot and the absence of a committee. Long-time Oak Park owners fourth, moving within the community to the one-level house.

For a buyer, read the plan off the square footage and the level, walk the lot before the house, and brief the inspector for the 1960s. Pull the permit history of any addition, pool or converted garage from the county. Confirm the school assignment for the exact address.

For a seller, the comparable is the same plan and level, and the top of the record — $1,753,000 — is the renovated house on the better lot. Price to the record for the plan, say the association fee and the school assignment in the first lines of the listing, and let the condition argue for the top of the band.
