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 392 ft of exterior wall, and across 5 residential floors the building carries 1,775 ft of it in total, divided among the 35 homes this screen estimates.
Its plate is moderately compact at 0.70: 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 7.0 homes per floor, repeated on every residential floor, since this building's outline does not change as it rises.

Score components for 1485 Delgany 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 23 out of 100: 35 estimated homes, scored from 0 up to 150.
What the conversion would cost
$360 per square foot all-in across 33,170 sq ft of converted floor, or $11.9M in total — about $341K for each of the 35 homes.
All-in cost per square foot for 1485 Delgany St: base cost plus the code work a change of use triggers.
| Base conversion cost | $260/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 | $360/sq ft |
That cost is charged across every converted square foot, including the 304 sq ft of windowless core, which has to be gutted, re-plumbed and sprinklered like the rest of the building and then earns nothing. Against it the model sets a completed value of $236K a home, which for 35 homes is $8.3M.
What would have to be true
A $3.7M gap before any grant, $1.6M after the modeled one. The smallest single change that would close it: average unit size 14% down.
The shortfall before any grant is $3.7M. Closing it from the value side means each of the 35 homes finishing at $341K rather than the $236K the model assumes — 45% more. Closing it from the cost side means getting all-in cost down from $360 to $249 per square foot.
A modeled RESIDE grant of $2.1M moves that threshold to $281K a home. That is still above the $236K assumed, leaving $1.6M uncovered, which is why the grant does not unlock this one.
Nor do all four levers have to move. For 1485 Delgany St, one alone would close the gap at:

Its nearest match in size: 333 W Colfax Ave
The screened building closest to 1485 Delgany St in converted floor area is 333 W Colfax Ave: 31,760 sq ft over 6 stories, against 33,170 sq ft over 6 here.
The two land within a few points of each other — 85 here, 85 there — so at this size the screen reads them as much the same prospect. On the money they sit in the same place: each falls short even with the modeled grant. The two stand about 5,400 ft apart.
Would it qualify for a RESIDE Act grant?
The model awards 1485 Delgany St $2.1M, 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.
