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 764 ft of exterior wall, and across 11 residential floors the building carries 9,193 ft of it in total, divided among the 256 homes this screen estimates.
Its plate is moderately compact at 0.55: 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 23.3 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 99 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.

Score components for 303 E 17th Ave. 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 23 out of 100: remaining gap is 46% of conversion cost, scored from 60% down to 0%.
What the conversion would cost
$360 per square foot all-in across 362,902 sq ft of converted floor, or $130.6M in total — about $510K for each of the 256 homes.
All-in cost per square foot for 303 E 17th Ave: 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 122,185 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 256 homes is $60.4M.
What would have to be true
A $70.2M gap before any grant, $60.2M after the modeled one. The smallest single change that would close it: average unit size 50% down.
The shortfall before any grant is $70.2M. Closing it from the value side means each of the 256 homes finishing at $510K rather than the $236K the model assumes — 116% more. Closing it from the cost side means getting all-in cost down from $360 to $166 per square foot.
A modeled RESIDE grant of $10.0M moves that threshold to $471K a home. That is still above the $236K assumed, leaving $60.2M uncovered, which is why the grant does not unlock this one.
Nor do all four levers have to move. For 303 E 17th Ave, one alone would close the gap at:

Within North Capitol Hill and the PUD zone
40th of 41 in North Capitol Hill, 17th of 21 zoned PUD — the comparison that shares its rules, rents and streets.
Denver places 41 of the screened buildings in North Capitol Hill. 303 E 17th Ave ranks 40th of them against a median score of 85. 32 score 70 or more, their median deepest interior point is 47 ft from a facade against this building’s 59 ft, and together they would hold an estimated 8,820 homes. The group’s top scorer is 1776 N Grant St, at 97.
21 of the screened buildings are zoned PUD. 303 E 17th Ave ranks 17th 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. The group’s top scorer is 300 E 17th Ave, at 96.
Its nearest match in size: 1101 13th St
The screened building closest to 303 E 17th Ave in converted floor area is 1101 13th St: 342,702 sq ft over 12 stories, against 362,902 sq ft over 12 here.
303 E 17th Ave scores 56 to its 71, and with the size held roughly equal most of that shortfall comes from daylight efficiency: 53 out of 100 here, 87 there (83% 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 4,500 ft apart.
Would it qualify for a RESIDE Act grant?
The model awards 303 E 17th Ave $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.
