The plan: window line, shape and floor rhythm
34 ft of exterior wall for each home the screen estimates — enough for two- and three-bedroom homes across the plan.
The typical floor has 795 ft of exterior wall, and across 6 residential floors the building carries 4,769 ft of it in total, divided among the 140 homes this screen estimates.
Its plate is moderately compact at 0.64: 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 23.3 homes per floor, repeated on every residential floor, since this building's outline does not change as it rises.
Why 333 W Julian St scores 61 out of 100

Score components for 333 W Julian St. Points are the subscore times its weight.

| Financeremaining gap is 13% of conversion cost, scored from 60% down to 0% | 79 | 15% | 11.8 |
Most of what it earns comes from daylight efficiency, and what holds it back most is interior depth, at 35 out of 100: deepest interior point 66 ft from a facade, scored from 80 ft down to 40 ft.
What the conversion would cost
$405 per square foot all-in across 192,066 sq ft of converted floor, or $77.8M in total — about $556K for each of the 140 homes.
All-in cost per square foot for 333 W Julian 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 59,882 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 $425K a home, which for 140 homes is $59.5M.
What would have to be true
A $18.3M gap before any grant, $9.9M after the modeled one. The smallest single change that would close it: average unit size 12% down.
The shortfall before any grant is $18.3M. Closing it from the value side means each of the 140 homes finishing at $556K rather than the $425K the model assumes — 31% more. Closing it from the cost side means getting all-in cost down from $405 to $310 per square foot.
A modeled RESIDE grant of $8.4M moves that threshold to $496K a home. That is still above the $425K assumed, leaving $9.9M uncovered, which is why the grant does not unlock this one.
Nor do all four levers have to move. For 333 W Julian St, one alone would close the gap at:

Would it qualify for a RESIDE Act grant?
The model awards 333 W Julian St $8.4M, 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.
This building does sit in census tract 06085500800, a 2018 designated Opportunity Zone, which Section 201 lets HUD favor — one of the few statutory priorities this screen can actually check.
