Oak Park is an unincorporated community of Ventura County, built out as a sequence of tracts from the late 1960s to the early 2000s under the county’s planning. Regency Hills and Chambord are the last chapter, on the east-side slopes above Deerhill Road, and Regency Hills came first: 1997 to 1999 in the recorded sales, with Chambord following in 2000 to 2002. A secondary source treats the two as one development phase and describes them as production-built, not gated, with Spanish and Mediterranean elevations and three-car garages. The builder is not named in any source Gary Jacobs has been able to verify, and this guide does not guess.

What the sale record shows is a tract of large late-1990s houses built for big families: five and six bedrooms in eight of the ten sales, on lots a little larger than Chambord’s, at a price a step below.

No plan sheet for Regency Hills 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 three plans: a 2,854-square-foot five-bedroom at the entry; a 3,308- to 3,428-square-foot five- or six-bedroom in the middle, the most common house; and a 3,644- to 3,716-square-foot five-bedroom at the top. All are two story. The six-bedroom count is unusual for the Conejo Valley and comes from a plan that gives up a bonus room or a loft for a sixth bedroom.

Deerbrook Road carries the most sales, with Ellesmere Way, Marquis Court and Lambourne Place behind it. The top of the record is on Deerbrook Road: $2,165,000 in May 2026 for a 3,308-square-foot six-bedroom on an 11,100-square-foot lot, and $2,029,500 in April 2023 for a 3,395-square-foot six-bedroom. The lot is what separates those from the $1,630,000 on Marquis Court in September 2025 for the smallest plan on 7,000.

The reasons buyers choose Regency Hills over the 1980s tracts are the things that are hard to retrofit: a family room open to the kitchen, a real primary suite, a downstairs bedroom and bath in most plans, higher ceilings, a three-car garage, copper or PEX plumbing rather than the late-1980s question mark, and dual-pane glazing from the start. Against Chambord next door, Regency Hills is a few years older and a size smaller, and trades about $350,000 lower at the median; against Morrison Estates and Sutton Valley, it is a decade newer on a lot two-thirds the size at a median about $250,000 lower.

The first reason is bedrooms: five or six in most of the record, which is rare anywhere in the Conejo Valley below $2,000,000. The second is the house, a late-1990s plan with the family room, the primary suite and the three-car garage. The third is the district, with a Brookside assignment that has no ambiguity in the street list. The fourth is the price against Chambord: the same street network, a few years older, about $350,000 less at the median.

2026 sales show the Regency Hills fee at $200 a month; listings since 2020 have reported $133 to $200 a month, and the amenities they carry are greenbelt, hiking trails, a picnic area, pickleball and landscape maintenance; one listing also carries security. The community is not gated according to a secondary source, so the fee is for common-area landscaping, the trail connections, the courts and architectural review; what it actually covers, and what the CC&Rs restrict, is not confirmed in any source Gary Jacobs has been able to verify. Take the budget, the reserve study and the CC&Rs from the seller’s disclosure package and read them before removing a contingency.

For underwriting, $200 a month on a $1,750,000 house is a small line. The practical effect of the association is on exteriors: paint, front yards and anything visible from the street go through review.

Regency Hills is in the Oak Park Unified School District, a small independent K–12 district that is one of the main reasons buyers choose Oak Park. The district publishes an elementary boundary street list, and every street in this tract’s sale record — Deerbrook Road, Ellesmere Way, Marquis Court and Lambourne Place — 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.

Regency Hills is on the east side of Oak Park above Deerhill Road, close to the Kanan and Lindero Canyon shopping center with the supermarket, restaurants and everyday services; everything else is in Agoura Hills or Westlake Village. Deerhill Park, with the community’s youth sports fields, is on the road below, and the Medea Creek trail is within walking distance. The Ventura Freeway is reached down Kanan Road to Agoura Hills, about eight to twelve minutes in normal traffic; like Chambord, Regency Hills is on the freeway side of the community.

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 May 2026, 5 homes in the tract sold through the MLS, at prices from $1,630,000 to $2,165,000 and a median of $1,750,000. The top three — $2,165,000 on Deerbrook Road in May 2026, $2,029,500 on Deerbrook Road in April 2023, $2,005,000 on Ellesmere Way in March 2023 — are six- and five-bedrooms of 3,308 to 3,644 square feet on the larger lots. The bottom is the 2020 baseline: $1,350,000 for a 3,308-square-foot six-bedroom on Ellesmere Way in July 2020 and $1,480,000 for a 3,716-square-foot five-bedroom on Marquis Court that November.

The shape of the six years is the same as the rest of Oak Park: a jump from 2020 into 2022 and a band since. A six-bedroom that sold for $1,350,000 in 2020 has traded at $2,029,500 to $2,165,000 since 2023 in comparable condition, a rise of roughly half. Ten sales in six years is a low turnover rate, and it is one reason the record is short: owners here stay.

These houses are about twenty-seven years old, and the list is the late-1990s one: original furnaces, water heaters and condensers at end of life; original appliances; tile-roof underlayment approaching the end of its span; and the questions about builder-grade windows, slab cracks and stucco that apply to any production house of the period. The plumbing is not the question it is in the 1980s tracts. On slope lots ask about drainage and retaining walls, and on any lot with a pool ask for the equipment’s age.

No lease is recorded in the MLS sources this guide draws on, so it does not quote a rent for the tract; a current figure should come from the leasing agents who work these streets. A five- or six-bedroom of the late 1990s in the Oak Park district is a scarce rental and is usually taken by a family relocating for the schools.

Start with the lot, because the record prices it: the two top sales are on the largest lots. Walk the yard and understand the slope. Then the plan, and whether six bedrooms is what you want or a bonus room would serve better. Then the association, from the disclosure package. Then the house, with the inspector briefed on the late-1990s list. A buyer who needs a single story should look elsewhere; every recorded sale here is two story.

Large families first, for whom the sixth bedroom is the point. Families moving up from a 1990s tract in Oak Park second, who want the bigger house without leaving the district. Relocations third, who arrive knowing the district’s reputation and want a house of this size at a price below Chambord and the county-line comparisons in Agoura Hills.

The comparison that matters most is Chambord, next door: 2000 to 2002, 3,075- to 4,010-square-foot five-bedrooms on lots around 7,100 square feet at a median of $2,100,000. Regency Hills is a few years older, a size smaller, on lots a little larger, and about $350,000 less. Morrison Estates and Sutton Valley, 1986 to 1989 on the north side, are 2,500- to 4,315-square-foot houses on lots around 12,900 at a median of $2,000,000, with a single-story option. Rolling Hills Estates, 1988 to 1989, is the step down: 1,860- to 3,136-square-foot houses on lots around 6,400 at a median of $1,185,000 with no fee.

For a buyer, read the plan off the square footage and the bedroom count, walk the lot, and brief the inspector on the late-1990s list. Pull the permit history of any pool or addition from the county, and take the fee and the CC&Rs from the disclosure package. Expect little inventory: ten sales in six years means a buyer who wants Regency Hills should be ready when one comes.

For a seller, the comparable is the same plan, and the top of the record — $2,165,000, $2,029,500, $2,005,000 — is the six- and five-bedrooms on the larger lots. If the lot is one of the large ones and the kitchen and baths are done, price to those; if not, price to the $1,630,000 to $1,850,000 band and let the bedroom count argue for the top of it.
