The plan: window line, shape and floor rhythm
41 ft of exterior wall for each home the screen estimates — enough for two- and three-bedroom homes across the plan.
The typical floor has 1,001 ft of exterior wall, and across 11 residential floors the building carries 10,583 ft of it in total, divided among the 259 homes this screen estimates.
Its plate is elongated at 0.28: a slab or an L, which is why so much of the floor lies within reach of a window: the outline buys daylight that a square plan of the same area would not. How window line and plate shape are measured.
At the model’s 750 sq ft average, the plan works out at about 23.5 homes per floor. Its floors are not alike, though: the typical floor's deepest interior point is 35 ft from a facade, while its worst floor reaches 64 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.
Why 724 17th St scores 94 out of 100
Daylight efficiency 100, Interior depth 100, Scale 100, Finance 62 — each out of 100, then weighted.
Score components for 724 17th St. Points are the subscore times its weight.
| Component | Subscore | Weight | Points |

| Financeremaining gap is 23% of conversion cost, scored from 60% down to 0% | 62 | 15% | 9.3 |
Most of what it earns comes from daylight efficiency, and what holds it back most is finance, at 62 out of 100: remaining gap is 23% of conversion cost, scored from 60% down to 0%.
What the conversion would cost
$360 per square foot all-in across 256,035 sq ft of converted floor, or $92.2M in total — about $356K for each of the 259 homes.
All-in cost per square foot for 724 17th 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 13,171 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 259 homes is $61.1M.
What would have to be true
A $31.0M gap before any grant, $21.0M after the modeled one. The smallest single change that would close it: average unit size 26% down.
The shortfall before any grant is $31.0M. Closing it from the value side means each of the 259 homes finishing at $356K rather than the $236K the model assumes — 51% more. Closing it from the cost side means getting all-in cost down from $360 to $239 per square foot.
A modeled RESIDE grant of $10.0M moves that threshold to $317K a home. That is still above the $236K assumed, leaving $21.0M uncovered, which is why the grant does not unlock this one.
Nor do all four levers have to move. For 724 17th St, one alone would close the gap at:

Within CBD and the D-C zone
5th of 74 in CBD, 3rd of 70 zoned D-C — the comparison that shares its rules, rents and streets.
Denver places 74 of the screened buildings in CBD. 724 17th St ranks 5th of them against a median score of 71. 38 score 70 or more, their median deepest interior point is 57 ft from a facade against this building’s 35 ft, and together they would hold an estimated 33,455 homes. The group’s top scorer is 918 17th St, at 97.
70 of the screened buildings are zoned D-C. 724 17th St ranks 3rd of them against a median score of 72. 36 score 70 or more, their median deepest interior point is 58 ft from a facade against this building’s 35 ft, and together they would hold an estimated 32,185 homes. The group’s top scorer is 721 19th St, at 95.
Its nearest match in size: 1351 16th St
The screened building closest to 724 17th St in converted floor area is 1351 16th St: 247,546 sq ft over 12 stories, against 256,035 sq ft over 12 here.
724 17th St scores 94 to its 77, and with the size held roughly equal most of that lead comes from interior depth: 100 out of 100 here, 54 there (deepest interior point 58 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 2,100 ft apart.
Would it qualify for a RESIDE Act grant?
The model awards 724 17th 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.
