Its block in Greater Downtown Denver, drawn from Denver's own building outlines and street centerlines.
- Already housing

- 1200 N Acoma St
This building does not pencil at default assumptions, even with a modeled RESIDE Act grant.
Across its 10 residential floors this building carries 171,248 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 0 condominiums here, alongside 11 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.
Read with caution. This footprint carries 6 street addresses across 100,443 sq ft, which usually means the city’s GIS has merged a block or complex into a single polygon rather than describing one convertible building.

The plan: window line, shape and floor rhythm
41 ft of exterior wall for each home the screen estimates — enough for two- and three-bedroom homes across the plan.
The typical floor has 1,551 ft of exterior wall, and across 10 residential floors the building carries 14,210 ft of it in total, divided among the 348 homes this screen estimates.
Its plate is moderately compact at 0.53: 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 34.8 homes per floor, repeated on every residential floor, since this building's outline does not change as it rises.
Why 1200 N Acoma St scores 35 out of 100
The weighted components add to 41, but the score is capped at 35 because its deepest interior point is 149 ft from a facade, past the 80 ft threshold beyond which conversion requires carving a light well.
Score components for 1200 N Acoma St. Points are the subscore times its weight.
| Component | Subscore | Weight | Points |
|---|---|---|---|
| Daylight efficiency66% of the floor area within 35 ft of a facade, scored from 40% up to 90% | 51 | 45% | 23.1 |
| Interior depthdeepest interior point 149 ft from a facade, scored from 80 ft down to 40 ft | 0 | 25% | 0.0 |

| Financeremaining gap is 49% of conversion cost, scored from 60% down to 0% | 19 | 15% | 2.8 |
Most of what it earns comes from daylight efficiency, and what holds it back most is interior depth, at 0 out of 100: deepest interior point 149 ft from a facade, scored from 80 ft down to 40 ft.
What the conversion would cost
$360 per square foot all-in across 498,318 sq ft of converted floor, or $179.4M in total — about $516K for each of the 348 homes.
All-in cost per square foot for 1200 N Acoma 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 171,248 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 348 homes is $82.1M.
What would have to be true
A $97.3M gap before any grant, $87.3M after the modeled one. The smallest single change that would close it: average unit size 51% down.
The shortfall before any grant is $97.3M. Closing it from the value side means each of the 348 homes finishing at $516K rather than the $236K the model assumes — 118% more. Closing it from the cost side means getting all-in cost down from $360 to $165 per square foot.
A modeled RESIDE grant of $10.0M moves that threshold to $487K a home. That is still above the $236K assumed, leaving $87.3M uncovered, which is why the grant does not unlock this one.
Nor do all four levers have to move. For 1200 N Acoma St, one alone would close the gap at:

How it compares in Greater Downtown Denver
1200 N Acoma St ranks 203rd of the 214 buildings screened here, against a median score of 72.
Its floor plate is better lit than 5% of them, and shallower than 1% of them at its deepest interior point. On size it is the 60th largest by estimated homes. The full survey of all 214 buildings ranks and maps every one of them, and the list by address links each to its own page.
Within Civic Center
19th of 23 in Civic Center — the comparison that shares its rules, rents and streets.
Denver places 23 of the screened buildings in Civic Center. 1200 N Acoma St ranks 19th of them against a median score of 67. 10 score 70 or more, their median deepest interior point is 62 ft from a facade against this building’s 149 ft, and together they would hold an estimated 5,064 homes. The group’s top scorer is 1314 N Elati St, at 92.
Its nearest match in size: 3600 Blake St
The screened building closest to 1200 N Acoma St in converted floor area is 3600 Blake St: 493,252 sq ft over 10 stories, against 498,318 sq ft over 11 here.
3600 Blake St scores 56 and 1200 N Acoma St only 35, and the difference is a hard fail rather than a matter of degree: the lower one is capped at 35 because its deepest interior point is 149 ft from a facade, past the 80 ft threshold beyond which conversion requires carving a light well. On the money they sit in the same place: each falls short even with the modeled grant. The two stand about 12,800 ft apart.
Would it qualify for a RESIDE Act grant?
The model awards 1200 N Acoma 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.
