The plan: window line, shape and floor rhythm
39 ft of exterior wall for each home the screen estimates — enough for two- and three-bedroom homes across the plan.
The typical floor has 471 ft of exterior wall, and across 13 residential floors the building carries 6,137 ft of it in total, divided among the 158 homes this screen estimates.
Its plate is compact at 0.76: close to a square or a circle, the most efficient envelope an office can have and the least generous one for apartments: little perimeter to divide among homes. How window line and plate shape are measured.
At the model’s 750 sq ft average, the plan works out at about 12.2 homes per floor. Its floors are not alike, though: the typical floor's deepest interior point is 47 ft from a facade, while its worst floor reaches 56 ft. The score follows the typical floor, so a podium that could not hold a bedroom does not by itself sink a slim tower above it — but it is there, and it is part of what would have to be drawn around.

Most of what it earns comes from daylight efficiency, and what holds it back most is finance, at 59 out of 100: remaining gap is 24% of conversion cost, scored from 60% down to 0%.
What the conversion would cost
$360 per square foot all-in across 171,982 sq ft of converted floor, or $61.9M in total — about $392K for each of the 158 homes.
All-in cost per square foot for 1900 N Grant 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 23,545 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 158 homes is $37.3M.
What would have to be true
A $24.6M gap before any grant, $15.1M after the modeled one. The smallest single change that would close it: average unit size 28% down.
The shortfall before any grant is $24.6M. Closing it from the value side means each of the 158 homes finishing at $392K rather than the $236K the model assumes — 66% more. Closing it from the cost side means getting all-in cost down from $360 to $217 per square foot.
A modeled RESIDE grant of $9.5M moves that threshold to $332K a home. That is still above the $236K assumed, leaving $15.1M uncovered, which is why the grant does not unlock this one.
Nor do all four levers have to move. For 1900 N Grant St, one alone would close the gap at:

The group’s top scorer is 1776 N Grant St, at 97.
16 of the screened buildings are zoned C-MX-12. 1900 N Grant St ranks 7th of them against a median score of 85. 13 score 70 or more, their median deepest interior point is 44 ft from a facade against this building’s 47 ft, and together they would hold an estimated 2,011 homes.

Its nearest match in size: 110 16th St
The screened building closest to 1900 N Grant St in converted floor area is 110 16th St: 172,888 sq ft over 15 stories, against 171,982 sq ft over 14 here.
1900 N Grant St scores 86 to its 82, and with the size held roughly equal most of that lead comes from interior depth: 82 out of 100 here, 72 there (deepest interior point 51 ft from a facade, scored from 80 ft down to 40 ft). On the money they sit in the same place: each falls short even with the modeled grant. The two stand about 2,300 ft apart.
The city's own study picked this building too
In August 2023 Denver and the architecture firm Gensler rated 21 downtown office buildings good candidates for conversion to housing and published the top 16 by address. One of them resolves to this building: “1900 Grant St”.
That is an outside opinion reached by different means — architects reading plans, not a model reading outlines — and this screen agrees with it: 1900 N Grant St scores 86 out of 100 here, in the same top tier. The difference is the money rather than the geometry: at default assumptions the gap here is $24.6M, which no modeled RESIDE grant closes. A study asking whether a building can be converted and a model asking whether it would pencil are answering different questions.

Would it qualify for a RESIDE Act grant?
The model awards 1900 N Grant St $9.5M, 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.
