Trousdale Estates

Trousdale Estates has an exact legal definition. The Beverly Hills city code defines it as all property north of Doheny Road and east of Schuyler Road, except the Greystone Mansion property and a small area zoned R-1.X. In practice that's the hillside rising from Doheny Road near Sunset up to the city line, with Loma Vista Drive as the main road through the middle and the City of Los Angeles on the east and north.

The houses sit on flat graded pads cut into the hill, most of them one level because of the height limit, and many with pools and glass walls turned toward the view. Greystone, the 1928 Doheny mansion, sits at the foot of the neighborhood, next to the ranch land Trousdale was carved from. Sunset Boulevard and the Beverly Hills Hotel are a few minutes down the hill, and Rodeo Drive is about 3 miles by car.

County records show about 540 houses in the neighborhood and about 40 vacant residential parcels. The median lot is about 22,000 square feet, roughly half an acre, and the middle half of lots run from about 20,400 to 28,400 square feet. The median house on record is about 4,700 square feet.

Every structure in Trousdale Estates is limited to 14 feet in height. The limit grew out of a fight in the 1980s: in 1987 the Los Angeles Times reported that about two thirds of the neighborhood was under a temporary 14-foot limit while homeowners argued over making it permanent. Today the code treats October 15, 1987 as the cutoff. A building that was legally taller on that date can be rebuilt within its old envelope, and adding height beyond 14 feet takes a Trousdale R-1 permit, with story poles put up first so neighbors can see the size.

The code also keeps building on the level pad. No part of a building can extend beyond the pad, except for fences and hedges that meet the rules, and structures built past the pad before October 15, 1987 can be kept but not expanded. No lot can be regraded to raise the pad, and grading that needs a permit isn't allowed on slopes steeper than 1 foot vertical for every 5 feet horizontal.

Floor area follows the same formula as the flats: all buildings on the lot together can't exceed 1,500 square feet plus 40% of the lot, and the main house has to be at least 1,600 square feet. A two-unit project under SB 9 shares that cap, and a lot split doesn't add floor area. Hedges and fences have their own limits, topping out at 8 feet in rear yards.

All of Trousdale sits in a Very High Fire Hazard Severity Zone on CAL FIRE's 2025 map, and the Beverly Hills Fire Department inspects every property in that zone for brush clearance on or after April 1 each year. On Red Flag days the city restricts parking on some streets north of Sunset so fire trucks can get in and residents can get out.

Get the insurance priced first. Many owners in high fire-risk areas now rely on the California FAIR Plan, which covers fire only and caps a house at $3 million per location, and its average rates were approved to rise 29.1% on policies starting October 15, 2026. A Trousdale house usually needs more coverage than that plus a second policy for liability and other risks, so get written quotes on the specific address.

Construction here has its own rules. After a construction-truck accident on Loma Vista Drive in 2014, the city suspended heavy hauling in Trousdale, and in 2015 it adopted Ordinance 15-O-2683. Heavy trucks now need city certification, a registered jobsite and 24 hours' notice, hauling is allowed only from 8:30 a.m. to 3:15 p.m., no vehicle of 50,400 pounds or more may use the streets, and no more than two construction vehicles per site can park on the street. If you're planning a rebuild, those rules shape the schedule and the budget.

I start with the height and the pad. Is any part of the house over 14 feet, and if so, was it legal on October 15, 1987? Does anything sit beyond the level pad, and was it permitted? Those answers decide what you can rebuild and what you'd lose in a teardown.

Then the view. I ask whether the house has been part of a view restoration case on either side, look at which neighbors' trees are within 500 feet of the view, and check the lots below for anything that could change the picture. The ordinance doesn't apply to city-owned trees, so a view over a park or a street tree isn't protected the same way.

Last, fire and cost of ownership: brush-clearance history, a written insurance quote, and the construction rules if you plan to rebuild. I have all of that done before anyone flies in to see houses.
