This building does not pencil at default assumptions, even with a modeled RESIDE Act grant.
Every floor carries 6,154 sq ft of windowless core — area that must be gutted, re-plumbed and sprinklered but can never be rented as an apartment. Across 17 residential floors that is 104,626 sq ft of cost carrying no revenue.

The plan: window line, shape and floor rhythm
36 ft of exterior wall for each home the screen estimates — enough for two- and three-bedroom homes across the plan.
The typical floor has 729 ft of exterior wall, and across 17 residential floors the building carries 12,385 ft of it in total, divided among the 344 homes this screen estimates.
Its plate is moderately compact at 0.60: 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 20.2 homes per floor, repeated on every residential floor, since this building's outline does not change as it rises.
Why 1400 Stout St scores 66 out of 100

Score components for 1400 Stout St. Points are the subscore times its weight.

Most of what it earns comes from daylight efficiency, and what holds it back most is finance, at 32 out of 100: remaining gap is 41% of conversion cost, scored from 60% down to 0%.
What the conversion would cost
$360 per square foot all-in across 428,015 sq ft of converted floor, or $154.1M in total — about $448K for each of the 344 homes.
All-in cost per square foot for 1400 Stout 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 104,626 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 344 homes is $81.2M.
What would have to be true
A $72.9M gap before any grant, $62.9M after the modeled one. The smallest single change that would close it: average unit size 44% down.
The shortfall before any grant is $72.9M. Closing it from the value side means each of the 344 homes finishing at $448K rather than the $236K the model assumes — 90% more. Closing it from the cost side means getting all-in cost down from $360 to $190 per square foot.
A modeled RESIDE grant of $10.0M moves that threshold to $419K a home. That is still above the $236K assumed, leaving $62.9M uncovered, which is why the grant does not unlock this one.
Nor do all four levers have to move. For 1400 Stout St, one alone would close the gap at:

Within CBD and the D-C zone
52nd of 75 in CBD, 50th of 72 zoned D-C — the comparison that shares its rules, rents and streets.
Denver places 75 of the screened buildings in CBD. 1400 Stout St ranks 52nd of them against a median score of 71. 40 score 70 or more, their median deepest interior point is 56 ft from a facade against this building’s 58 ft, and together they would hold an estimated 33,698 homes. The group’s top scorer is 918 17th St, at 97.
72 of the screened buildings are zoned D-C. 1400 Stout St ranks 50th of them against a median score of 73. 39 score 70 or more, their median deepest interior point is 57 ft from a facade against this building’s 58 ft, and together they would hold an estimated 32,881 homes. The group’s top scorer is 721 19th St, at 95.
Its nearest match in size: 901 19th St
The screened building closest to 1400 Stout St in converted floor area is 901 19th St: 434,350 sq ft over 21 stories, against 428,015 sq ft over 18 here.
1400 Stout St scores 66 to its 69, and with the size held roughly equal most of that shortfall comes from daylight efficiency: 71 out of 100 here, 83 there (82% of the floor area within 35 ft of a facade, scored from 40% up to 90%). On the money they sit in the same place: each falls short even with the modeled grant. The two stand about 2,500 ft apart.
Would it qualify for a RESIDE Act grant?
The model awards 1400 Stout 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.
