- 800 16th St
This building does not pencil at default assumptions, even with a modeled RESIDE Act grant.
Across its 10 residential floors this building carries 19,956 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 51 apartments 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
42 ft of exterior wall for each home the screen estimates — enough for two- and three-bedroom homes across the plan.
The typical floor has 1,063 ft of exterior wall, and across 10 residential floors the building carries 6,438 ft of it in total, divided among the 154 homes this screen estimates.
Its plate is elongated at 0.35: 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 15.4 homes per floor, repeated on every residential floor, since this building's outline does not change as it rises.
Why 800 16th St scores 85 out of 100
Daylight efficiency 96, Interior depth 71, Scale 100, Finance 61 — each out of 100, then weighted.
Score components for 800 16th St. 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 61 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 165,032 sq ft of converted floor, or $59.4M in total — about $386K for each of the 154 homes.
All-in cost per square foot for 800 16th 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 19,956 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 154 homes is $36.3M.
What would have to be true
A $23.1M gap before any grant, $13.8M after the modeled one. The smallest single change that would close it: average unit size 26% down.
The shortfall before any grant is $23.1M. Closing it from the value side means each of the 154 homes finishing at $386K rather than the $236K the model assumes — 63% more. Closing it from the cost side means getting all-in cost down from $360 to $220 per square foot.
A modeled RESIDE grant of $9.2M moves that threshold to $326K a home. That is still above the $236K assumed, leaving $13.8M uncovered, which is why the grant does not unlock this one.
Nor do all four levers have to move. For 800 16th St, one alone would close the gap at:

Within CBD and the D-C zone
17th of 75 in CBD, 14th of 72 zoned D-C — the comparison that shares its rules, rents and streets.
Denver places 75 of the screened buildings in CBD. 800 16th St ranks 17th 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 52 ft, and together they would hold an estimated 33,698 homes. The group’s top scorer is 918 17th St, at 97.
72 of the screened buildings are zoned D-C. 800 16th St ranks 14th of them against a median score of 73. 39 score 70 or more, their median deepest interior point is 57 ft from a facade against this building’s 52 ft, and together they would hold an estimated 32,881 homes. The group’s top scorer is 721 19th St, at 95.
Its nearest match in size: 1250 14th St
The screened building closest to 800 16th St in converted floor area is 1250 14th St: 161,849 sq ft over 11 stories, against 165,032 sq ft over 11 here.
800 16th St scores 85 to its 80, and with the size held roughly equal most of that lead comes from daylight efficiency: 96 out of 100 here, 88 there (84% 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 1,700 ft apart.
Would it qualify for a RESIDE Act grant?
The model awards 800 16th St $9.2M, 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.
