Kerman Morris Architects is responsible for the design. Renderings show a familiar vernacular style with sawtooth bay windows capped by an overexaggerated cornice. The building’s rear will feature several setbacks to provide space for private balconies overlooking Market Street.

The roughly 40-foot-tall structure is expected to yield around 24,140 square feet. Unit sizes will vary somewhat, with a two-bedroom residence, four three-bedroom units, and four four-bedroom units. Parking will be included for 12 cars and 16 bicycles.

Public records show the existing two-story house was constructed in the early 20th century. The building is not listed, and the architect is unknown, but it is considered age-eligible for historic resource designation.

The 0.16-acre property is located between Corbett Avenue and Market Street, close to the Rooftop TK-8 Elementary School. The estimated cost and timeline for construction have not yet been shared.

  1. Thanks for covering this. As a nearby neighbor, I’m surprised by the high parking space to unit ratio. I hope that the developer is aware of the very good bus service on Corbett Avenue (in addition to great service on Clayton nearby, along with 24/7 service at the Market and Clayton intersection). Our large family lives well without a car here.

      Per ChatGPT, a bus runs past Corbett Ave every 20-30 minutes. I wouldn’t call that very good, but it’s in the eye of the beholder I suppose…

    • As someone who also lives on that street, I can’t imagine not having a car. Most units there would be DOA without car parking. The bus isn’t frequent enough, and the climb down to Noe Valley is pretty steep. The proposed plans look great.

      • I appreciate your different perspective. As new housing is built that encourages car ownership and use (such as the 1&1/3 parking space per unit ratio here), we’re not only welcoming new neighbors but also more congestion, noise and air pollution and making our neighborhood (and city) less livable as a result.

        This increase in automobile use slows Muni (and increases its operating costs while discouraging ridership). Corbett Avenue is narrow and existing traffic levels impede Muni’s route 37 at times. Corbett Avenue is also a bicycle route and, in the absence of heavy car traffic, well suited for bicycling. Nearby Clayton Street has become very impacted by congestion over the past decade and this greatly slows Muni’s route 33 at numerous times throughout the day.

        Our future is being built around us and I believe we’d all be better off if such new housing was less welcoming of new cars.

  2. this is awesome. Great use of space. We need more of this all over the city.

        “The project will replace a single-family house with nine dwelling units.”

        More San Franciscans, yay! I don’t want SF to become Manhattan, either. I just want it to be Brooklyn (about double its current density).

  3. Corbett was once a toll road taking folks to the race tracks and truck farms west of Twin Peaks. There are lots of old Victorians and Edwardians on Corbett. I guess, in time, they will all be destroyed.

  4. As a long-time resident of the Twin Peaks area, I’m really tracking how this new development might impact our local community footprint. I noticed the article mentions Modern Art Construction as the firm behind the project, but details on the overall corporate backing and timeline seem a bit scarce. While searching for more background on their broader portfolio and financial reliability, I came across a highly detailed corporate transparency review on GuiadeLuvaBetbrasil.com which raised some interesting questions about how modern digital brands disclose their ownership. Does anyone know if there is a similar, comprehensive independent audit available for local San Francisco contractors like Modern Art Construction so we can verify their track record before construction begins?

  5. I think the project looks great. I’ve seen other developments from this builder, and they deliver beautiful homes that are much needed.

  6. Bottom line: we need to increase housing supply. Net gain for the win. Great that this project won’t take away valuable street parking!

  7. This looks like a terrific project! I particularly like that it includes units to meet the needs of larger families.

  8. One of my favorite features of houses on Corbett is when you’re passing by and there’s suddenly a passage through which you see an incredible view. Sadly, this building doesn’t have one.

  9. Does the city need more multimillion dollar housing? Developer is abusing the new planning laws to push this through without committee oversight. Check public records for his other projects and felonies. Seems a bit shady.

    bus rider, not everyone works in the city & so some must have cars to go to work. Not all transit goes everywhere & the way the city is going that bus you count on might not be there in the future, so u might be walking or paying for Uber to take you places. Everyone thinks bikes are great, but unfortunately they, electric & scooters r not regulated & can be quite dangerous. Hope your children don’t get hit by some young person w/o a license driving an electric bike @ 40 mph. Not that a regular bike would be on Corbett St hills. So maybe parking that is not taking up city streets could be welcome too.
