A TERNER CENTER REPORT - FEBRUARY 2021

savings realized in 833 Bryant arise from
the design of the building, which includes
small units and ecient programming. For
example, the project has very little common
space and the units are stacked vertically
and there is no need for excess circulation
spaces. There is a single oor plan for all
units, allowing the o-site manufacturer
to program one large construction run,
maximizing their production eciency.
While there are non-apartment uses in the
building, including two small retail spaces
and oces for the supportive services
sta, these uses comprise a relatively small
portion of the total building area.
The design of 1064 Mission is far less cost-
ecient than it could have been because the
use of public subsidies required additional
processes that aected the project’s design.
In many regards 1064 Mission will be very
similar to 833 Bryant: it is permanent
supportive housing composed of 100
percent small studio units developed by
Mercy Housing with o-site construction
by Factory_OS. The project is much larger,
with 256 units, compared to 833 Bryant’s
145. In theory economies of scale might
be expected to result in a lower per-unit
total development cost for 1064 Mission.
However, excluding acquisition costs,
1064 Mission will cost about 25 percent
more. 1064 Mission will cost $509,826 per
unit, relative to $382,917 for 833 Bryant.
Much of this higher cost came from cost-
inecient design decisions that arose due
to design review. For example, the Planning
Department expected the project to have
an active use on the rst oor on Mission
Street. For this reason, the project includes
a large commercial kitchen which will
provide space for a culinary arts training
program for unhoused individuals as well
as building residents. The project also has
a large amount of community space. The
number of units in the project relative to
the size of the site is substantially lower
than 833 Bryant because of community
concerns over the total number of units
in the project. The developers estimate
that an additional 20 units could have
been easily accommodated in the site,
through a combination of making the units
smaller and reprogramming space from
community uses to residential uses. The
studio units in 1064 Mission are about 35
percent larger than the units in 833 Bryant,
measuring 350 square feet compared to
833 Bryant’s 260 square feet.
The design of Mission Bay Block 9 was
made even more cost-inecient than 1064
Mission in large part because of additional
layers of public review. Mission Bay Block 9
will be 140 units of permanent supportive
housing composed of 100 percent studios
developed by BRIDGE Housing and
Community Housing Partnership with
o-site construction by Factory_OS.
The units for this project, however, cost
33 percent more than 833 Bryant, at
$573,218 per unit. The high per-unit
costs were driven in large part because
this supportive housing project contains
relatively little housing. The lot for Mission
Bay Block 9 is about three times the size
of 833 Bryant, but the project will have
fewer units. The dearth of housing on the
site is largely due to design review that was
required because the Oce of Community
Investment and Infrastructure (OCII,
formerly the San Francisco Redevelopment
Authority) provided the land and subsidy.
OCII required that the program for the
site conform to plans passed in the 1990s,
which limited the number of aordable
units on the site. The developers had
initially programmed the site for nearly
twice as many units, with 120 senior units
and 130 units for adults, instead of the
140 total units that were constructed. The
initial design had a height that was in line
