A Rare Offering
Iconic Nob Hill Elegance

Nestled atop storied Nob Hill and directly across from the landmark Mark Hopkins Hotel, 843 Mason Street is a rare architectural treasure. Designed in 1917 by the legendary Willis Polk, this home is part of an exclusive row of classic townhouses that embody the timeless sophistication of early 20th-century San Francisco.

This stunning residence seamlessly combines refined classical detailing with grand proportions, resulting in a private urban home that feels both impressive in scale and peaceful in character. One of only a handful of homes in this historically significant enclave, it presents a rare opportunity to own a lasting piece of San Francisco’s architectural legacy.

Spanning approximately 4,427 square feet (per Open Homes floor plan), the residence unfolds across four thoughtfully designed levels, offering a rare combination of versatility, scale, and timeless charm. The entry level welcomes you through a gated courtyard and features a guest suite with kitchenette, a family/media room, powder room, laundry, and a flexible bedroom or office spaces. One level up, the main living floor is perfectly suited for both everyday comfort and elegant entertaining, with a formal living room and fireplace, a gracious dining room, and a generous eat-in kitchen bathed in natural light from French doors and windows.

On the third level, two spacious en suite bedrooms offer privacy and comfort, with one opening to a west-facing deck ideal for enjoying San Francisco’s golden-hour light. The top floor is dedicated to a luxurious primary suite—a private sanctuary with direct access to a rooftop terrace offering sweeping city views.

Set in one of the city’s most prestigious neighborhoods, 843 Mason is surrounded by iconic landmarks and amenities. Grace Cathedral, Huntington Park, the Fairmont and Mark Hopkins hotels, world-class restaurants, and the cable car line are just steps away, with Union Square, the Financial District, and Russian Hill close by. Leased parking is conveniently available nearby at the Crocker Garage.

This is more than a home—it’s a timeless piece of San Francisco’s architectural heritage, designed by a master and located in one of the city’s most celebrated settings.
