As we outlined earlier this year:

The ground for the 141-unit modular development to rise on Mission Bay South Block 9, adjacent to San Francisco’s new Public Safety Building and across the street from Phase 2 of the Giants’ massive Mission Rock development, is tentatively slated to be broken this June.

If everything goes as planned, the four-story development will take around 17 months to complete (versus closer to 24 months if fully built on-site) and should be ready for occupancy by the end of next year.

The development will be managed by BRIDGE Housing and Community Housing Partnership.

And once again, the 141 studio units, which will average around 400 square feet apiece and had been projected to cost around $427,000 per unit to develop, including common areas but not accounting for the value of the underlying (publicly-owned) land, will be made available to currently homeless and extremely low-income households earning less than 30 percent of the area median income, the individual threshold for which is currently $25,850 per year or $29,550 for a couple.

While the ground floor of the building will be constructed on-site, the upper floor modules will be constructed by Factory OS on Mare Island in Vallejo and trucked to the Block 9 site for final assembly, as newly rendered below.

And the total budget for the 141-unit development, which now includes $13.6 million in soft costs and a $3.11 million developer fee, but still doesn’t account for the value of the underlying, publicly-owned land (which is being leased for a buck), is up to $81,359,601 or roughly $577,000 per unit and $812 per square foot.

  1. Would it actually cost *more* than $812/sqft to build if non-modular construction technology was being use?

      1. So-called “affordable” housing is some of the most expensive housing to create — as everyone needs to get their “slice-of-the-pie”, the unions, the politicians, the “non-profit” developers, whose developer fee is double of what is standard in the “marketrate” sector.

        This project is even more expensive per square foot then the notorious Sunnydale re-build reported on last year.

        “Luxury” housing — for the lucky few –,brought to you courtesy of the taxpayers.

    1. I think that’s a reasonable question to ask. The statewide average for a new affordable unit under the Low-Income Housing Tax Credit (LIHTC) program (not saying that’s the same program the above project used) is $700 per ft² as of 2019. The majority of those units are not modular construction.

      Maybe the selling point is that modular construction isn’t as susceptible to the quality shortcuts that on-site stick construction contractors like to pull all the time in multi-family projects.

    2. We now have two more recent data points. Tahanan Supportive Housing (at 833 Bryant St.) completed in winter 2021, was built 30 percent faster than traditional stick construction ’cause the project was designed as 145 units of modular — prefabricated off-site — over a concrete podium, using the same modular housing supplier as 410 China Basin Street (the project featured in the above main post, a.k.a. HomeRise at Mission Bay) at a cost of roughly $400,000 per unit, around $1530 per ft.².
      The other one is 1633 Valencia St. which didn’t go all in on modular. From a piece bylined by Kevin Nguyen published in The San Francisco Standard (This group just built affordable housing in SF for half the price and twice as fast), 2nd ‘graph:

      The affordable community for 145 formerly homeless seniors in the Mission was unveiled Tuesday, just 19 months after breaking ground, at a cost of approximately $525,000 per unit. That’s about half of the $1 million per unit cost for most Bay Area housing projects.

      Such radical savings were possible because the developer, Mercy Housing, and its partners and lenders were aligned from the very start and made compromises rather than waiting for ideal settings – declining interest rates or the return of federal or state funding – according to Housing Accelerator Fund CEO Rebecca Foster.

      Rather than follow the industry template of soliciting public money before construction — which would have triggered more applications and locked in strict rules for how 1633 Valencia could be built and operated — Mercy Housing used HAF’s private funding upfront to provide its partners with the financial certainty to start construction quickly.
      Rather than figuring out how to achieve time and cost savings, developers are often jumping through hoops required by their capital, Foster said.

      With HAF’s financing secured, Mercy Housing turned its attention to building smarter – starting by bringing back the architect and contractor from a 2022 project at 833 Bryant St. and reusing elements of that design.
      However, rather than relying on modular construction…the designers of 1633 Valencia used select prefabricated elements where practical, Foster said.

      Read the whole thing if you have any interest in affordable housing. The San Francisco Department of Homelessness and Supportive Housing was able to select affordable housing developer Mercy Housing California without competitive bidding because of a clause in the city’s administrative code that allows it to bypass the process if services are tied to addressing homelessness.
      The per-unit cost of approximately $525,000 works out to around $1750 per ft.².

    1. Agreed. I think this is a case where, especially given the taller context of much of the area, the case for going higher is pretty inarguable.

  2. I’m curious, how do the management (Bridge and Community Housing Partnership) go about recruiting tenants? Is there a lottery like other BMR units? Do they stop by the local encampments and sign people up?

    Would tenants ever move out of units like this? I certainly wouldn’t if I were making 30% of the AMI…

    1. This project is reserved for the currently homeless — so if you don’t fall into this category, you’re outta luck.

  3. Two questions –
    1. How did cost get to $800 per sq ft without land cost?
    2. How does a person making $25K afford a $570K mortgage?

    But GLAD to see project like this which, hopefully, proves to the CITY it is not that smart at all…..

    1. The units will be rentals and residents will pay 30 percent of their monthly income toward rent, with a target income of up to 30 percent of the Area Median Income (AMI) for new residents and a maximum allowable income of up to 60 percent of the AMI (which would equate to a maximum rent of $1,293 per month based on the current AMI), allowing for both stability and upward mobility at the same time.

    2. Prevailing wage labor
      Impact fees
      Fixed percentage development fee – more expensive, bigger fee
      Not sure about the funding (probably tax-credit?) but not traditional profit-driven incentives

  4. The map (showing the intersection of 4th Street and MB Blvd South) is wrong by several blocks for the location of the proposed building.

  5. $577k per unit is pretty good, especially given today’s LA Times story about a waylaid affordable project that would cost $1.1 million per unit. Granted the unit sizes are totally different, but I’ll take our victories on cost when we get them.

  6. Parcel 9 is 1.08 acres next to waterfront, a premium piece of land. Any commercial RE out there? Curious to what is the appraisal value of the land if placed on the market for sale to private developers like the Warriors, a bio tech, condo builder, hotel builder? $50 million?

  7. Houses can be bought on Ohio for $50 a sq. ft. But we have to spend $800 a sq. ft to value signal for a very exclusive few lottery winners in San Francisco. “Progressive” politics are truly the road to hell paved with allegedly “good” intentions.

      1. Anonymous is practicing “ad hominem” attacks by primarily denigrating the motives of Clyde Benke, instead of his argument. Therefore, Anonymous displays cowardice (in the name choice), as well as the very qualities purported to exist in another.

  8. It is probably a better use of money to sell the land to the highest bidder, and then donate the development funds to fund homeless people moving to a different area–with a lower cost of living (and where more could be assisted and are more likely to be gainfully employed). This would assist in breaking the cycle of systemic poverty in an increasingly service and technology-based economy that will continue to gentrify and become more expensive.

    However, the vested interests of the local homeless-development complex would lose their own employment and/or societal virtue signaling in this scenario. Therefore, it will never happen.

    1. This isn’t housing targeted at the recently homeless. You’ve invented a counter-factual thing to argue against.

      1. “will be made available to currently homeless and extremely low-income households”
