This building does not pencil on its own, but a modeled RESIDE Act grant would close the gap if the building qualified for one.
This footprint has no windowless core at all: every point on the floor plate is within 35 ft of a facade, which is unusual and is the main reason it scores as well as it does.

The plan: window line, shape and floor rhythm
51 ft of exterior wall for each home the screen estimates — enough for two- and three-bedroom homes across the plan.
The typical floor has 427 ft of exterior wall, and across 5 residential floors the building carries 2,134 ft of it in total, divided among the 42 homes this screen estimates.
Its plate is moderately compact at 0.55: a squarish plan, with enough perimeter for a conventional double-loaded corridor. How window line and plate shape are measured.
At the model’s 750 sq ft average, the plan works out at about 8.4 homes per floor, repeated on every residential floor, since this building's outline does not change as it rises.
Why 1067 Market St scores 89 out of 100
Daylight efficiency 100, Interior depth 100, Scale 28, Finance 100 — each out of 100, then weighted.
Score components for 1067 Market St. Points are the subscore times its weight.

Most of what it earns comes from daylight efficiency, and what holds it back most is scale, at 28 out of 100: 42 estimated homes, scored from 0 up to 150.
Built in 1924
San Francisco records this building as going up in 1924, which puts it in the interwar stock.
As a rule, steel or concrete frames with punched windows and plates still narrow enough for daylight to reach the middle, often with high ceilings. Among the most convertible stock there is, and the reason so many early conversions were of buildings this age. That is the era’s general tendency rather than a finding about this building — the model reads an outline and a height, and can see nothing inside — but it is the first thing an architect would want to know, and it colours how much confidence the 100% daylight figure above deserves.
What the conversion would cost
$405 per square foot all-in across 39,504 sq ft of converted floor, or $16.0M in total — about $381K for each of the 42 homes.
All-in cost per square foot for 1067 Market St: base cost plus the code work a change of use triggers.
| Base conversion cost | $260/sq ft |
|---|---|
| Seismic retrofit (change of use) | $45/sq ft |
| Plumbing risers to every unit | $40/sq ft |
| Operable windows and glazing | $30/sq ft |
| Additional egress stair | $18/sq ft |
| Fire sprinklers (NFPA 13R) | $12/sq ft |
| All-in | $405/sq ft |
That cost is charged across every converted square foot, including the circulation and service area that earns nothing directly. Against it the model sets a completed value of $366K a home, which for 42 homes is $15.4M.
What would have to be true
A $627K gap before any grant, which the modeled $2.5M closes. What would reopen it soonest: circulation efficiency 10% down.
The shortfall before any grant is $627K. Closing it from the value side means each of the 42 homes finishing at $381K rather than the $366K the model assumes — 4% more. Closing it from the cost side means getting all-in cost down from $405 to $389 per square foot.
A modeled RESIDE grant of $2.5M moves that threshold to $321K a home. That is below the assumed value, which is why this building counts as unlocked by the grant — subject to it qualifying under the law's vacant-and-abandoned test, which this data cannot show.
Each of these, moved on its own, would be enough to undo that for 1067 Market St:

How it compares in Downtown San Francisco
1067 Market St ranks 80th of the 205 buildings screened here, against a median score of 87.
Its floor plate is better lit than 100% of them, and shallower than 96% of them at its deepest interior point. On size it is the 184th largest by estimated homes. The full survey of all 205 buildings ranks and maps every one of them, and the list by address links each to its own page.
Within South of Market and the C-3-G zone
6th of 14 in South of Market, 5th of 22 zoned C-3-G — the comparison that shares its rules, rents and streets.
San Francisco places 14 of the screened buildings in South of Market. 1067 Market St ranks 6th of them against a median score of 82. 9 score 70 or more, their median deepest interior point is 45 ft from a facade against this building’s 24 ft, and together they would hold an estimated 2,045 homes. The group’s top scorer is 431 Natoma St, at 100.
22 of the screened buildings are zoned C-3-G. 1067 Market St ranks 5th of them against a median score of 76. 13 score 70 or more, their median deepest interior point is 51 ft from a facade against this building’s 24 ft, and together they would hold an estimated 2,588 homes. The group’s top scorer is 40 Leavenworth St, at 92.
Its nearest match in size: 118 2nd St
The screened building closest to 1067 Market St in converted floor area is 118 2nd St: 38,861 sq ft over 6 stories, against 39,504 sq ft over 6 here.
The two land within a few points of each other — 89 here, 89 there — so at this size the screen reads them as much the same prospect. On the money they sit in the same place: each pencils only with the modeled RESIDE grant. The two stand about 4,200 ft apart.
Would it qualify for a RESIDE Act grant?
The model awards 1067 Market St $2.5M, on the assumption it qualifies. Whether it does, no published dataset can say.
That figure assumes the building meets the Act’s vacant-and-abandoned test, which turns on code-enforcement and receivership records no city publishes.
It does not sit in a 2018 designated Opportunity Zone, so it would not draw that Section 201 priority.
