The plan: window line, shape and floor rhythm
37 ft of exterior wall for each home the screen estimates — enough for two- and three-bedroom homes across the plan.
The typical floor has 676 ft of exterior wall, and across 6 residential floors the building carries 3,600 ft of it in total, divided among the 97 homes this screen estimates.
Its plate is moderately compact at 0.72: 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 16.2 homes per floor, repeated on every residential floor, since this building's outline does not change as it rises.
Why 1705 17th St scores 47 out of 100
Daylight efficiency 59, Interior depth 23, Scale 65, Finance 34 — each out of 100, then weighted.
Score components for 1705 17th St. Points are the subscore times its weight.

| Financeremaining gap is 39% of conversion cost, scored from 60% down to 0% | 34 | 15% | 5.2 |
Most of what it earns comes from daylight efficiency, and what holds it back most is interior depth, at 23 out of 100: deepest interior point 71 ft from a facade, scored from 80 ft down to 40 ft.
What the conversion would cost
$360 per square foot all-in across 131,440 sq ft of converted floor, or $47.3M in total — about $488K for each of the 97 homes.
All-in cost per square foot for 1705 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 39,829 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 97 homes is $22.9M.
What would have to be true
A $24.4M gap before any grant, $18.6M after the modeled one. The smallest single change that would close it: average unit size 39% down.
The shortfall before any grant is $24.4M. Closing it from the value side means each of the 97 homes finishing at $488K rather than the $236K the model assumes — 107% more. Closing it from the cost side means getting all-in cost down from $360 to $174 per square foot.
A modeled RESIDE grant of $5.8M moves that threshold to $428K a home. That is still above the $236K assumed, leaving $18.6M uncovered, which is why the grant does not unlock this one.
Nor do all four levers have to move. For 1705 17th St, one alone would close the gap at:

Within Union Station
55th of 55 in Union Station — the comparison that shares its rules, rents and streets.
Denver places 55 of the screened buildings in Union Station. 1705 17th St ranks 55th of them against a median score of 69. 23 score 70 or more, their median deepest interior point is 61 ft from a facade against this building’s 71 ft, and together they would hold an estimated 13,167 homes. The group’s top scorer is 1600 17th St, at 95.
Its nearest match in size: 1120 N Delaware St
The screened building closest to 1705 17th St in converted floor area is 1120 N Delaware St: 128,425 sq ft over 7 stories, against 131,440 sq ft over 7 here.
1705 17th St scores 47 to its 60, and with the size held roughly equal most of that shortfall comes from interior depth: 23 out of 100 here, 46 there (deepest interior point 62 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 7,400 ft apart.
Would it qualify for a RESIDE Act grant?
The model awards 1705 17th St $5.8M, 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.
