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
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 686 ft of exterior wall, and across 8 residential floors the building carries 4,971 ft of it in total, divided among the 130 homes this screen estimates.
Its plate is moderately compact at 0.46: 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 16.3 homes per floor, repeated on every residential floor, since this building's outline does not change as it rises.
Why 1651 N Logan St scores 95 out of 100
Daylight efficiency 100, Interior depth 100, Scale 87, Finance 79 — each out of 100, then weighted.
Score components for 1651 N Logan St. Points are the subscore times its weight.
| Component | Subscore | Weight | Points |

| Financeremaining gap is 12% of conversion cost, scored from 60% down to 0% | 79 | 15% | 11.9 |
Most of what it earns comes from daylight efficiency, and what holds it back most is finance, at 79 out of 100: remaining gap is 12% of conversion cost, scored from 60% down to 0%.
What the conversion would cost
$360 per square foot all-in across 122,008 sq ft of converted floor, or $43.9M in total — about $338K for each of the 130 homes.
All-in cost per square foot for 1651 N Logan 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 circulation and service area that earns nothing directly. Against it the model sets a completed value of $236K a home, which for 130 homes is $30.7M.
What would have to be true
A $13.2M gap before any grant, $5.4M after the modeled one. The smallest single change that would close it: average unit size 13% down.
The shortfall before any grant is $13.2M. Closing it from the value side means each of the 130 homes finishing at $338K rather than the $236K the model assumes — 43% more. Closing it from the cost side means getting all-in cost down from $360 to $251 per square foot.
A modeled RESIDE grant of $7.8M moves that threshold to $278K a home. That is still above the $236K assumed, leaving $5.4M uncovered, which is why the grant does not unlock this one.
Nor do all four levers have to move. For 1651 N Logan St, one alone would close the gap at:

Its nearest match in size: 1115 N Acoma St
The screened building closest to 1651 N Logan St in converted floor area is 1115 N Acoma St: 119,272 sq ft over 8 stories, against 122,008 sq ft over 9 here.
1651 N Logan St scores 95 to its 90, and with the size held roughly equal most of that lead comes from finance: 79 out of 100 here, 67 there (remaining gap is 20% of conversion cost, scored from 60% down to 0%). On the money they sit in the same place: each falls short even with the modeled grant. The two stand about 3,500 ft apart.
Would it qualify for a RESIDE Act grant?
The model awards 1651 N Logan St $7.8M, 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.
