- 1400 Wewatta St
This building does not pencil at default assumptions, even with a modeled RESIDE Act grant.
Across its 10 residential floors this building carries 124,347 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 22 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
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 1,504 ft of exterior wall, and across 10 residential floors the building carries 13,028 ft of it in total, divided among the 357 homes this screen estimates.
Its plate is elongated at 0.28: 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 35.7 homes per floor. Its floors are not alike, though: the typical floor's deepest interior point is 61 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 1400 Wewatta 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 28 out of 100: remaining gap is 43% of conversion cost, scored from 60% down to 0%.
What the conversion would cost
$360 per square foot all-in across 459,906 sq ft of converted floor, or $165.6M in total — about $464K for each of the 357 homes.
All-in cost per square foot for 1400 Wewatta 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 124,347 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 357 homes is $84.3M.
What would have to be true
A $81.3M gap before any grant, $71.3M after the modeled one. The smallest single change that would close it: average unit size 46% down.
The shortfall before any grant is $81.3M. Closing it from the value side means each of the 357 homes finishing at $464K rather than the $236K the model assumes — 97% more. Closing it from the cost side means getting all-in cost down from $360 to $183 per square foot.
A modeled RESIDE grant of $10.0M moves that threshold to $436K a home. That is still above the $236K assumed, leaving $71.3M uncovered, which is why the grant does not unlock this one.
Nor do all four levers have to move. For 1400 Wewatta St, one alone would close the gap at:

How it compares in Greater Downtown Denver
1400 Wewatta St ranks 162nd of the 214 buildings screened here, against a median score of 72.
Its floor plate is better lit than 22% of them, and shallower than 39% of them at its deepest interior point. On size it is the 59th 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 Union Station and the D-LD zone
41st of 55 in Union Station, 24th of 29 zoned D-LD — the comparison that shares its rules, rents and streets.
Denver places 55 of the screened buildings in Union Station. 1400 Wewatta St ranks 41st of them against a median score of 69. 23 score 70 or more, their median deepest interior point is 61 ft from a facade against this building’s 61 ft, and together they would hold an estimated 13,167 homes. The group’s top scorer is 1600 17th St, at 95.
29 of the screened buildings are zoned D-LD. 1400 Wewatta St ranks 24th of them against a median score of 68. 10 score 70 or more, their median deepest interior point is 61 ft from a facade against this building’s 61 ft, and together they would hold an estimated 5,069 homes. The group’s top scorer is 1600 17th St, at 95.
Its nearest match in size: 1301 N Broadway
The screened building closest to 1400 Wewatta St in converted floor area is 1301 N Broadway: 437,965 sq ft over 11 stories, against 459,906 sq ft over 11 here.
1400 Wewatta St scores 61 and 1301 N Broadway 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 87 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 6,400 ft apart.
Would it qualify for a RESIDE Act grant?
The model awards 1400 Wewatta 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.
