Updated plans have been shared for a potential residential expansion at 45 Montclair Terrace in San Francisco’s Russian Hill neighborhood. The proposal would replace a single-family house with a two-unit building half a block away from the city’s iconic winding block of Lombard Street. Domaine Montclair LLC is listed as the project applicant.

The roughly 54-foot-tall structure is expected to yield around 9,700 square feet, including a four-bedroom 7,980 square foot primary residence above a 665 square foot one-bedroom accessory dwelling unit. Parking will be included for two cars and two bicycles.

San Francisco-based Y.A. Studio is responsible for the design. Illustrations show a bare contemporary-style design with floor-to-ceiling windows clad in cement plaster. The exterior will be split to appear like two separate structures using setbacks, a mid-building terrace, and rooftop decks.

The property is located along Monclair Terrace between Lombard Street and Chestnut Street. Public records show the property last sold in 2021 for $3.75 million. Construction is expected to cost around $1.4 million, a figure that does not include all development costs.

  1. This is great. We should encourage the mega-millionaires build their dream homes in SF. Let’s assume this house is valued at $15M. They will be paying $177,000 in property taxes *every year* to SF. They will be employing construction workers, architects and interior designers for at least a year, and likely a variety of cleaning, nannies or other staff ongoing. Any of the doom and gloom about the finances of SF, such as the sales tax decline, or the woes of downtown, gets offset a tiny bit, every time one of these mansions gets built and that new ongoing growth kicks in.

  2. Interesting that the current home is blurred out on Google Streetview, the only blurred house on that cut-de-sac. Presume fabulous Bay views, but the only street outlet is to the crooked block of Lombard, which could be a hassle many months. Good luck with the project.

    God forbid we have any vegetation showing on this desolate tech bro pad. Tech ruined San Francisco. They don’t appreciate its charm at all. I honestly don’t know why they come here. I am hoping for an AI bust just as much as an obituary for our dear leader.

    • By its charm, do you mean when Hayes Valley had a freeway running through it, with drug dealing and prostitution underneath? When Mission Bay and Dogpatch were just a series of parking lots and warehouses? When Dolores Park had grass three feet tall? When Alamo Square had murders on it all the time? When you couldn’t get a taxi ride at all if you lived in certain neighborhoods? When SoMa was filled with surface parking lots? When the Ferry Building was obfuscated by a freeway? When Market St was filled with strip clubs? When was this magical time?

        Of course, many things have changed for the better, and several of those things you mentioned I had a hand in realizing – fun fact!

        But you can’t deny that the tech bro aesthetic, with its harsh, functional, mechanistic, stripped-down aesthetic does not allow for any messiness, history, patina, flowers, weeds, or funkiness. Everything has to look like an apple store or a Dave n’ Buster’s.

        Maybe it’s because I am a Gen X liberal arts major, but I don’t want to see every flower-filled lot with a funky-ass cottage destroyed to make way for a hulking tech bro pad where the inhabitants contribute nothing to the community….ordering Uber Eats and driving into their massive garage, on their way back from Silicon Valley, in their Wankpanzer, err, Cybertruck.

        Fortunately, they haven’t destroyed everything yet. There is still lots of unprogrammed funk and happenstance in much of the city, including 24th Street in the Mission, the Inner Sunset, Glen Canyon, the Excelsior, etc.

        You can keep Hayes Valley and your industrial restaurants in the Marina.

        • “a hulking tech bro pad where the inhabitants contribute nothing to the community…”

          This home will contribute $177,000 every year to the city in the form of property taxes. Never mind the millions of dollars of one-time economic impact to build it, and the hundreds of thousands per year of ongoing money this individual will be spending locally in the area. This person may also be an employer of other people.

          We need people like this.

  4. YAY Super expensive single-family house with a TINY unit that will NEVER, EVER be a rental unit. Just what we need! These folks are using Wiener’s legislation to build a McMansion for themselves…don’t be fooled. Why is YIMBY touting this like some amazing solution?

      YIMBY is all about servicing the Big Development that feeds them.

      • Rental prices peaked in San Francisco around 2015 and started dropping in 2016, right in the middle of the boom. Wonder why that is? Thanks to a new supply of housing that started coming online. The tech wave wasn’t going to be stopped and a one bedroom would have been $4,500. YIMBY saved SF.

          Except that is not true. Rents peaked in San Francisco in 2019 right before the Pandemic. The only reason they came down is that the Libertarian tech bros fled to Austin and Miami because they didn’t like wearing masks.

          P.S., what did YIMBY have to do with all of those new luxury buildings like NEMA that emptied out during the Pandemic?
