Overview
About Lambert Ranch
Lambert Ranch does not appear in the City of Irvine's village layer. The city records it instead as master homeowner association 6.2, the Lambert Ranch Maintenance Corporation, and the polygon the city draws for that association is the boundary used here: about 48 acres sitting entirely inside the Portola Springs village and inside Planning Area 6. Inside it the city's address record carries 170 residential addresses on nine streets, Cunningham with 34, Harrison with 31, Clifford with 28, Forbes with 19, Parson Brown with 18, Everett with 15, Peacevine with 10, Heirloom with 9 and Andrews with 6. The parcel record for the same ground carries 249 parcels, 39 of them classified Private Street, which is why the roadway here is association property rather than public street, and the city's gated community entrance layer places two entrance points on the boundary. One master association governs all of it with no second tier beneath it, managed by Keystone Pacific Property Management, so an address here answers to one set of governing documents rather than two.
The shared building is the Ranch House at the center of the plan. The builder describes it as a recreation and social building of 2,000 square feet holding a 1,500 square foot club room with catering facilities, an outdoor verandah and view deck, a Junior Olympic sized swimming pool, a wading pool, a spa, an outdoor kitchen with barbecues and a loggia. The project architect records the same single story building at 2,154 square feet on a 0.9 acre site with a community room, bar, kitchen, covered outdoor areas, restrooms and outdoor showers, and the two published sizes are left as they were published rather than averaged. Three pocket parks and a 0.75 acre playground the builder calls the Children's Adventure Park sit inside the same boundary, and the city's parcel record classifies four parcels here as Neighborhood Park and another 34 as Landscape Maintenance. Every campus is Irvine Unified, and the city's school district layer records no other district over this ground: Portola Springs Elementary and Loma Ridge Elementary both name Jeffrey Trail Middle and Portola High as their feeders, and Portola High's published attendance area covers northeastern Irvine east of Sand Canyon Avenue, naming the Portola Springs village this community sits inside.

How Lambert Ranch was built
The name on the gates belonged to a family that actually farmed here. The Lambert family started a ranch on this ground in 1915 and worked it while the Irvine Ranch, and then the city of Irvine, grew up around them. When the land was finally sold for development the heirs, two sisters who were by then both in their nineties, chose to stay on the property, and the family house was kept rather than cleared. That is a rare thing in a city where almost everything standing was built after residents voted to incorporate in December 1971.
The New Home Company of Aliso Viejo built the community, 169 detached houses on about 43 acres behind gates, a little under four homes to the acre. Robert Hidey Architects did the land planning, the lotting, the community theming and every house type, along with the community buildings. The houses went up in 2012 and 2013 across three neighborhoods named The Field, The Hill and The Grove, running from about 2,730 to 5,125 square feet. At the center of it the architects put the Ranch House, a single-story building of 2,154 square feet holding a community room, a bar, a kitchen, restrooms and covered outdoor space, which serves all 169 homes.

Schools serving Lambert Ranch
Lambert Ranch is inside the Irvine Unified School District, and the city's school district layer records no other district over this ground. Portola High School's published attendance area covers northeastern Irvine east of Sand Canyon Avenue and names Portola Springs, the village this community sits inside, so Portola High is the assigned high school. The elementary and middle assignment is a different matter. Two Irvine Unified elementary campuses stand in the village, Portola Springs Elementary and Loma Ridge Elementary, and each names Jeffrey Trail Middle and Portola High as the campuses it feeds. No published source places either elementary attendance boundary over Lambert Ranch, so neither is presented here as the assigned school and both are shown on the same footing. Irvine Unified adjusts boundaries periodically, so confirm the assignment for a specific address with the district before relying on it.

FAQs
Common questions about Lambert Ranch
What do homes in Lambert Ranch sell for?
No median is published on this page, because there is no defensible sample to compute one from. Lambert Ranch has no MLS area of its own. Matching the City of Irvine's 170 Lambert Ranch addresses against every CRMLS export held in this vault returns three listings in total, of which one has closed, and a single closing is not a market figure. All three are filed under MLS Area PS - Portola Springs with the subdivision written in as Lambert Ranch, all three are detached single family homes, and all three carry a build year of 2013. Portola Springs, the wider village this community sits inside, closed 85 homes at a median of $1,785,000 between 15 January and 17 July 2026, but most of what closed there was attached housing, so that number describes the village rather than this community. Pricing an address here is a comparable-by-comparable exercise across the nine streets and the three floor plan groups, not a lookup.
Is there Mello Roos at Lambert Ranch?
The builder announced on 21 February 2012 that there would be no Mello Roos taxes at Lambert Ranch, and called it the only new home community in Irvine at that time offering no additional tax assessment. That is the builder's statement, dated 2012. The City of Irvine's own map of Irvine Unified community facilities districts is consistent with it: a query at the center of the community returns no district, and the two nearest districts touch only the edge of the boundary. That layer covers school district districts alone, and a special tax or assessment can come from other agencies, so the answer for a specific address is the county tax bill and the transfer disclosure package rather than a community-wide claim.
Which schools serve Lambert Ranch?
All of them are Irvine Unified, and the city's school district layer records no other district over this ground. Portola High School serves grades 9 through 12 with 2,693 students, reports a 94.6 percent graduation rate and offers 98 AP courses, and its published attendance area covers northeastern Irvine east of Sand Canyon Avenue and names Portola Springs, the village Lambert Ranch sits inside. Below that the assignment is not established for this community by any source read here. Jeffrey Trail Middle School serves grades 7 and 8 with 1,049 students at 76 percent English and 74 percent math met or exceeded, and is named as the feeder middle school by both elementary campuses in the village. Those two campuses are Portola Springs Elementary, K through 6 with 948 students at 72 percent English and 71 percent math, and Loma Ridge Elementary, PK through 6 with 766 students at 75 percent English and 71 percent math. Neither is shown here as the assigned elementary, because no published source places either boundary over Lambert Ranch. Confirm the assignment for the exact address with Irvine Unified before it matters.
Is Lambert Ranch in a fire hazard severity zone?
Yes, and the zone changes from street to street inside the community. Sampling one address on each of the nine residential streets against the City of Irvine's fire hazard severity zone layer returned Very High at 55 Parson Brown, 66 Heirloom, 62 Peacevine, 66 Clifford and 78 Harrison, and High at 74 Forbes, 55 Cunningham, 54 Andrews and 56 Everett. All nine sit in the Local Responsibility Area, which puts the city rather than the state in charge of fire protection there. The zone drives insurance quotes and the defensible space and building material requirements that come with it, so pull the zone for the exact address rather than for the community.
What is the Ranch House?
It is the community's recreation and social building, the only shared building inside the boundary. The builder describes it as 2,000 square feet holding a 1,500 square foot club room with catering facilities, an outdoor verandah and view deck, a Junior Olympic sized swimming pool, a wading pool, a spa, an outdoor entertaining area with a fireplace, an outdoor kitchen with barbecues, a permanent ping pong table and a loggia. Robert Hidey Architects, who designed it, records the same single story building at 2,154 square feet on a 0.9 acre site with a community room, bar, kitchen, covered outdoor areas, restrooms and outdoor showers. The two published sizes are left as they were published. The 2006 approval that created the community required a 1.77 acre neighborhood park with a resort and lap pool and a community building, and the city's parcel record shows four park parcels inside the boundary, the largest of them 1.606 acres.
