- 140 E 19th Ave
This building does not pencil at default assumptions, even with a modeled RESIDE Act grant.
This footprint has no windowless core at all: every point on the floor plate is within 35 ft of a facade, which is unusual and is the main reason it scores as well as it does.

The plan: window line, shape and floor rhythm
50 ft of exterior wall for each home the screen estimates — enough for two- and three-bedroom homes across the plan.
The typical floor has 319 ft of exterior wall, and across 7 residential floors the building carries 2,236 ft of it in total, divided among the 45 homes this screen estimates.
Its plate is compact at 0.76: 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 6.4 homes per floor, repeated on every residential floor, since this building's outline does not change as it rises.
Why 140 E 19th Ave scores 86 out of 100
Daylight efficiency 100, Interior depth 100, Scale 30, Finance 77 — each out of 100, then weighted.
Score components for 140 E 19th Ave. Points are the subscore times its weight.

| Financeremaining gap is 14% of conversion cost, scored from 60% down to 0% | 77 | 15% | 11.6 |
Most of what it earns comes from daylight efficiency, and what holds it back most is scale, at 30 out of 100: 45 estimated homes, scored from 0 up to 150.
What the conversion would cost
$360 per square foot all-in across 42,919 sq ft of converted floor, or $15.5M in total — about $343K for each of the 45 homes.
All-in cost per square foot for 140 E 19th Ave: 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 circulation and service area that earns nothing directly. Against it the model sets a completed value of $236K a home, which for 45 homes is $10.6M.
What would have to be true
A $4.8M gap before any grant, $2.1M after the modeled one. The smallest single change that would close it: average unit size 14% down.
The shortfall before any grant is $4.8M. Closing it from the value side means each of the 45 homes finishing at $343K rather than the $236K the model assumes — 45% more. Closing it from the cost side means getting all-in cost down from $360 to $247 per square foot.
A modeled RESIDE grant of $2.7M moves that threshold to $283K a home. That is still above the $236K assumed, leaving $2.1M uncovered, which is why the grant does not unlock this one.
Nor do all four levers have to move. For 140 E 19th Ave, one alone would close the gap at:

Within North Capitol Hill and the C-MX-16 zone
15th of 41 in North Capitol Hill, 2nd of 7 zoned C-MX-16 — the comparison that shares its rules, rents and streets.
Denver places 41 of the screened buildings in North Capitol Hill. 140 E 19th Ave ranks 15th of them against a median score of 85. 32 score 70 or more, their median deepest interior point is 47 ft from a facade against this building’s 29 ft, and together they would hold an estimated 8,820 homes. The group’s top scorer is 1776 N Grant St, at 97.
7 of the screened buildings are zoned C-MX-16. 140 E 19th Ave ranks 2nd of them against a median score of 79. 6 score 70 or more, their median deepest interior point is 51 ft from a facade against this building’s 29 ft, and together they would hold an estimated 556 homes. The group’s top scorer is 1905 N Sherman St, at 87.
Its nearest match in size: 1673 N Sherman St
The screened building closest to 140 E 19th Ave in converted floor area is 1673 N Sherman St: 41,481 sq ft over 7 stories, against 42,919 sq ft over 8 here.
The two land within a few points of each other — 86 here, 84 there — so at this size the screen reads them as much the same prospect. On the money they sit in the same place: each falls short even with the modeled grant. The two stand about 1,100 ft apart.
Would it qualify for a RESIDE Act grant?
The model awards 140 E 19th Ave $2.7M, 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.
