At $400 million, 11201 Chalon Road in Bel-Air was the highest-priced active Zillow listing we could verify on August 30, 2026. That makes it an extraordinary asking price—not a sale, an appraisal or proof that anybody will pay it.

The listing describes roughly 70,000 square feet across 7.86 acres, with 39 bedrooms and 59 bathrooms. The price works out to about $5,714 per interior square foot, $10.26 million per bedroom and $6.78 million per bathroom. Those divisions are deliberately ridiculous, but they reveal how little ordinary housing math explains a property marketed as a one-of-one trophy.

What $400 million is supposed to buy

The Beverly Hills Estates calls the property the “Crown Jewel of Los Angeles”—broker language, not an independent designation. Its listing credits architect and designer Peter Marino and builder Peter McCoy, says the estate was completed in 2018, and describes a main residence plus additional structures, extensive wellness and fitness spaces, and views stretching from downtown Los Angeles toward the Pacific.

Forbes reported that the owners spent more than $350 million developing the estate over roughly a decade. The brokerage materials separate family and staff accommodations, including ten family bedrooms and thirteen staff bedrooms. The remaining room count belongs to an estate designed less like a house than a private compound.

The price math is spectacle

A $400 million list price is more than three times the property’s Zillow-displayed tax assessment of about $123.5 million. Assessments are not appraisals and are governed by local tax rules, so that comparison does not tell us the “correct” value. It does show how far the public asking price sits outside familiar residential benchmarks.

If a sale closed near the ask, it would challenge the record books. Until then, the number is a marketing position chosen by the seller. Headlines that call it “the most expensive home in America” should preserve that distinction: it is the most expensive publicly offered residence reported by Forbes, not the most expensive completed transaction.
