- 1111 14th St
This building does not pencil at default assumptions, even with a modeled RESIDE Act grant.
Across its 45 residential floors this building carries 153,439 sq ft of windowless core — area that must be gutted, re-plumbed and sprinklered but can never be rented as an apartment.
Part of this building is already homes. Denver's property records list 203 condominiums here, alongside 2 non-residential records. The figures here treat the whole building as convertible, so read them as an upper bound and check which floors are already housing.

The plan: window line, shape and floor rhythm
40 ft of exterior wall for each home the screen estimates — enough for two- and three-bedroom homes across the plan.
The typical floor has 519 ft of exterior wall, and across 45 residential floors the building carries 24,577 ft of it in total, divided among the 614 homes this screen estimates.
Its plate is moderately compact at 0.65: 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 13.6 homes per floor. Its floors are not alike, though: the typical floor's deepest interior point is 49 ft from a facade, while its worst floor reaches 81 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 1111 14th St scores 74 out of 100
Daylight efficiency 78, Interior depth 77, Scale 100, Finance 32 — each out of 100, then weighted.
Score components for 1111 14th St. Points are the subscore times its weight.
| Component | Subscore | Weight | Points |

| Daylight efficiency79% of the floor area within 35 ft of a facade, scored from 40% up to 90% | 78 | 45% | 35.1 |

| Financeremaining gap is 41% of conversion cost, scored from 60% down to 0% | 32 | 15% | 4.7 |
Most of what it earns comes from daylight efficiency, and what holds it back most is finance, at 32 out of 100: remaining gap is 41% of conversion cost, scored from 60% down to 0%.
What the conversion would cost
$360 per square foot all-in across 729,333 sq ft of converted floor, or $262.6M in total — about $428K for each of the 614 homes.
All-in cost per square foot for 1111 14th 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 153,439 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 614 homes is $144.9M.
What would have to be true
A $117.7M gap before any grant, $107.7M after the modeled one. The smallest single change that would close it: average unit size 43% down.
The shortfall before any grant is $117.7M. Closing it from the value side means each of the 614 homes finishing at $428K rather than the $236K the model assumes — 81% more. Closing it from the cost side means getting all-in cost down from $360 to $199 per square foot.
A modeled RESIDE grant of $10.0M moves that threshold to $411K a home. That is still above the $236K assumed, leaving $107.7M uncovered, which is why the grant does not unlock this one.
Nor do all four levers have to move. For 1111 14th St, one alone would close the gap at:

Within CBD and the D-TD zone
35th of 75 in CBD, 9th of 20 zoned D-TD — the comparison that shares its rules, rents and streets.
Denver places 75 of the screened buildings in CBD. 1111 14th St ranks 35th of them against a median score of 71. 40 score 70 or more, their median deepest interior point is 56 ft from a facade against this building’s 49 ft, and together they would hold an estimated 33,698 homes. The group’s top scorer is 918 17th St, at 97.
20 of the screened buildings are zoned D-TD. 1111 14th St ranks 9th of them against a median score of 69. 10 score 70 or more, their median deepest interior point is 57 ft from a facade against this building’s 49 ft, and together they would hold an estimated 8,599 homes. The group’s top scorer is 918 17th St, at 97.
Its nearest match in size: 1999 N Broadway
The screened building closest to 1111 14th St in converted floor area is 1999 N Broadway: 830,340 sq ft over 46 stories, against 729,333 sq ft over 46 here.
1111 14th St scores 74 to its 83, and with the size held roughly equal most of that shortfall comes from daylight efficiency: 78 out of 100 here, 100 there (91% 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 2,900 ft apart.
Would it qualify for a RESIDE Act grant?
The model awards 1111 14th 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.
