The plan: window line, shape and floor rhythm
51 ft of exterior wall for each home the screen estimates — enough for two- and three-bedroom homes across the plan.
The typical floor has 1,147 ft of exterior wall, and across 7 residential floors the building carries 5,221 ft of it in total, divided among the 102 homes this screen estimates.
Its plate is elongated at 0.33: 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 14.6 homes per floor. Its floors are not alike, though: the typical floor's deepest interior point is 59 ft from a facade, while its worst floor reaches 68 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 1711 19th St scores 79 out of 100
Daylight efficiency 100, Interior depth 54, Scale 68, Finance 70 — each out of 100, then weighted.
Score components for 1711 19th St. Points are the subscore times its weight.
| Component | Subscore | Weight | Points |

| Financeremaining gap is 18% of conversion cost, scored from 60% down to 0% | 70 | 15% | 10.5 |
Most of what it earns comes from daylight efficiency, and what holds it back most is interior depth, at 54 out of 100: deepest interior point 59 ft from a facade, scored from 80 ft down to 40 ft.
What the conversion would cost
$360 per square foot all-in across 102,474 sq ft of converted floor, or $36.9M in total — about $362K for each of the 102 homes.
All-in cost per square foot for 1711 19th 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 6,024 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 102 homes is $24.1M.
What would have to be true
A $12.8M gap before any grant, $6.7M after the modeled one. The smallest single change that would close it: average unit size 18% down.
The shortfall before any grant is $12.8M. Closing it from the value side means each of the 102 homes finishing at $362K rather than the $236K the model assumes — 53% more. Closing it from the cost side means getting all-in cost down from $360 to $235 per square foot.
A modeled RESIDE grant of $6.1M moves that threshold to $302K a home. That is still above the $236K assumed, leaving $6.7M uncovered, which is why the grant does not unlock this one.
Nor do all four levers have to move. For 1711 19th St, one alone would close the gap at:

Within Union Station and the PUD zone
16th of 55 in Union Station, 10th of 21 zoned PUD — the comparison that shares its rules, rents and streets.
Denver places 55 of the screened buildings in Union Station. 1711 19th St ranks 16th 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 59 ft, and together they would hold an estimated 13,167 homes. The group’s top scorer is 1600 17th St, at 95.
21 of the screened buildings are zoned PUD. 1711 19th St ranks 10th of them against a median score of 77. 12 score 70 or more, their median deepest interior point is 49 ft from a facade against this building’s 59 ft, and together they would hold an estimated 5,808 homes.

Its nearest match in size: 1845 N Sherman St
The screened building closest to 1711 19th St in converted floor area is 1845 N Sherman St: 107,568 sq ft over 8 stories, against 102,474 sq ft over 8 here.
1711 19th St scores 79 to its 63, and with the size held roughly equal most of that lead comes from daylight efficiency: 100 out of 100 here, 78 there (79% 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 4,900 ft apart.
Would it qualify for a RESIDE Act grant?
The model awards 1711 19th St $6.1M, 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.
