- 2000 Arapahoe St
This building does not pencil at default assumptions, even with a modeled RESIDE Act grant.
Across its 12 residential floors this building carries 23,738 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 52 condominiums here, alongside 1 non-residential record. 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
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 574 ft of exterior wall, and across 12 residential floors the building carries 5,774 ft of it in total, divided among the 140 homes this screen estimates.
Its plate is compact at 0.73: close to a square or a circle, the most efficient envelope an office can have and the least generous one for apartments: little perimeter to divide among homes. How window line and plate shape are measured.
At the model’s 750 sq ft average, the plan works out at about 11.7 homes per floor, repeated on every residential floor, since this building's outline does not change as it rises.
Why 2000 Arapahoe St scores 74 out of 100
Daylight efficiency 89, Interior depth 44, Scale 93, Finance 57 — each out of 100, then weighted.
Score components for 2000 Arapahoe St. Points are the subscore times its weight.

| Financeremaining gap is 26% of conversion cost, scored from 60% down to 0% | 57 | 15% | 8.5 |
Most of what it earns comes from daylight efficiency, and what holds it back most is interior depth, at 44 out of 100: deepest interior point 63 ft from a facade, scored from 80 ft down to 40 ft.
What the conversion would cost
$360 per square foot all-in across 155,461 sq ft of converted floor, or $56.0M in total — about $400K for each of the 140 homes.
All-in cost per square foot for 2000 Arapahoe 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 23,738 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 140 homes is $33.0M.
What would have to be true
A $22.9M gap before any grant, $14.5M after the modeled one. The smallest single change that would close it: average unit size 28% down.
The shortfall before any grant is $22.9M. Closing it from the value side means each of the 140 homes finishing at $400K rather than the $236K the model assumes — 69% more. Closing it from the cost side means getting all-in cost down from $360 to $213 per square foot.
A modeled RESIDE grant of $8.4M moves that threshold to $340K a home. That is still above the $236K assumed, leaving $14.5M uncovered, which is why the grant does not unlock this one.
Nor do all four levers have to move. For 2000 Arapahoe St, one alone would close the gap at:

How it compares in Greater Downtown Denver
2000 Arapahoe St ranks 103rd of the 214 buildings screened here, against a median score of 72.
Its floor plate is better lit than 57% of them, and shallower than 24% of them at its deepest interior point. On size it is the 140th 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 Five Points
9th of 20 in Five Points — the comparison that shares its rules, rents and streets.
Denver places 20 of the screened buildings in Five Points. 2000 Arapahoe St ranks 9th of them against a median score of 68. 9 score 70 or more, their median deepest interior point is 61 ft from a facade against this building’s 63 ft, and together they would hold an estimated 5,122 homes. The group’s top scorer is 3355 Denargo St, at 90.
Its nearest match in size: 2005 17th St
The screened building closest to 2000 Arapahoe St in converted floor area is 2005 17th St: 157,607 sq ft over 12 stories, against 155,461 sq ft over 13 here.
2000 Arapahoe St scores 74 to its 87, and with the size held roughly equal most of that shortfall comes from interior depth: 44 out of 100 here, 87 there (deepest interior point 45 ft from a facade, scored from 80 ft down to 40 ft). On the money they sit in the same place: each falls short even with the modeled grant. The two stand about 3,600 ft apart.
Would it qualify for a RESIDE Act grant?
The model awards 2000 Arapahoe St $8.4M, 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.
