40 Jessie St

Where 40 Jessie 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

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

The typical floor has 356 ft of exterior wall, and across 4 residential floors the building carries 1,422 ft of it in total, divided among the 27 homes this screen estimates.

Its plate is moderately compact at 0.65: 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 6.8 homes per floor, repeated on every residential floor, since this building's outline does not change as it rises.

Why 40 Jessie St scores 88 out of 100

Daylight efficiency 100, Interior depth 100, Scale 18, Finance 100 — each out of 100, then weighted.

Most of what it earns comes from daylight efficiency, and what holds it back most is scale, at 18 out of 100: 27 estimated homes, scored from 0 up to 150.

Built in 2008

San Francisco records this building as going up in 2008, which puts it in the modern stock.

As a rule, newer systems and better structure, but usually built deep and sealed for office use, and rarely cheap enough to buy at a price that lets a conversion pencil. 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 26,055 sq ft of converted floor, or $10.6M in total — about $391K for each of the 27 homes.

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 27 homes is $9.9M.

What would have to be true

A $670K gap before any grant, which the modeled $1.6M closes. What would reopen it soonest: completed value per home 10% down.

The shortfall before any grant is $670K. Closing it from the value side means each of the 27 homes finishing at $391K rather than the $366K the model assumes — 7% more. Closing it from the cost side means getting all-in cost down from $405 to $379 per square foot.

A modeled RESIDE grant of $1.6M moves that threshold to $331K 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 40 Jessie St:

How it compares in Downtown San Francisco

40 Jessie St ranks 98th 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 78% of them at its deepest interior point. On size it is the 200th 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 Financial District/South Beach and the C-3-O(SD) zone

82nd of 165 in Financial District/South Beach, 19th 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. 40 Jessie St ranks 82nd 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 32 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). 40 Jessie St ranks 19th 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 32 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: 647 Mission St

The screened building closest to 40 Jessie St in converted floor area is 647 Mission St: 24,953 sq ft over 5 stories, against 26,055 sq ft over 5 here.

The two land within a few points of each other — 88 here, 88 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 1,100 ft apart.

Would it qualify for a RESIDE Act grant?

The model awards 40 Jessie St $1.6M, 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.
