575 Market St

Where 575 Market St is

Its block in Downtown San Francisco, drawn from San Francisco's own building outlines and street centerlines.

The plan: window line, shape and floor rhythm

38 ft of exterior wall for each home the screen estimates — enough for two- and three-bedroom homes across the plan.

The typical floor has 476 ft of exterior wall, and across 39 residential floors the building carries 18,564 ft of it in total, divided among the 489 homes this screen estimates.

Its plate is moderately compact at 0.71: 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 12.5 homes per floor, repeated on every residential floor, since this building's outline does not change as it rises.

Why 575 Market St scores 97 out of 100

Daylight efficiency 100, Interior depth 96, Scale 100, Finance 88 — each out of 100, then weighted.

Most of what it earns comes from daylight efficiency, and what holds it back most is finance, at 88 out of 100: remaining gap is 7% of conversion cost, scored from 60% down to 0%.

Built in 1975

San Francisco records this building as going up in 1975, which puts it in the late-modern stock.

As a rule, typically the hardest to convert: the deepest plates of any era, large central cores, and floor-to-floor heights tight enough that running residential drainage under a ceiling can be the thing that ends a project. 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 91% daylight figure above deserves.

What the conversion would cost

$405 per square foot all-in across 502,172 sq ft of converted floor, or $203.4M in total — about $416K for each of the 489 homes.

That cost is charged across every converted square foot, including the 43,437 sq ft of windowless core, which has to be gutted, seismically braced and sprinklered like the rest of the building and then earns nothing. Against it the model sets a completed value of $366K a home, which for 489 homes is $179.0M.

What would have to be true

A $24.4M gap before any grant, $14.4M after the modeled one. The smallest single change that would close it: average unit size 8% down.

The shortfall before any grant is $24.4M. Closing it from the value side means each of the 489 homes finishing at $416K rather than the $366K the model assumes — 14% more. Closing it from the cost side means getting all-in cost down from $405 to $356 per square foot.

A modeled RESIDE grant of $10.0M moves that threshold to $395K a home. That is still above the $366K assumed, leaving $14.4M uncovered, which is why the grant does not unlock this one.

Nor do all four levers have to move. For 575 Market St, one alone would close the gap at:

Within Financial District/South Beach and the C-3-O(SD) zone

29th of 165 in Financial District/South Beach, 7th of 66 zoned C-3-O(SD) — the comparison that shares its rules, rents and streets.

San Francisco places 165 of the screened buildings in Financial District/South Beach. 575 Market St ranks 29th of them against a median score of 88. 121 score 70 or more, their median deepest interior point is 47 ft from a facade against this building’s 42 ft, and together they would hold an estimated 40,456 homes. The group’s top scorer is 870 Market St, at 100.

66 of the screened buildings are zoned C-3-O(SD). 575 Market St ranks 7th of them against a median score of 72. 37 score 70 or more, their median deepest interior point is 59 ft from a facade against this building’s 42 ft, and together they would hold an estimated 18,546 homes. The group’s top scorer is 140 New Montgomery St, at 100.

Its nearest match in size: 600 Market St

The screened building closest to 575 Market St in converted floor area is 600 Market St: 462,327 sq ft over 38 stories, against 502,172 sq ft over 40 here.

575 Market St scores 97 to its 85, and with the size held roughly equal most of that lead comes from interior depth: 96 out of 100 here, 66 there (deepest interior point 54 ft from a facade, scored from 80 ft down to 40 ft). On the money they sit in the same place: each falls short even with the modeled grant. The two stand about 700 ft apart.

Would it qualify for a RESIDE Act grant?

The model awards 575 Market St $10.0M, 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.
