918 17th St is a 10-story building in Greater Downtown Denver with 100% of its floor area within daylight reach of a facade. This screen estimates 176 homes and scores it 97 out of 100 for office-to-residential conversion suitability.
CO-1 · Screened 2026-10-04 · Strong candidate
No address point in Denver’s records falls inside this footprint, so it is named by the closest one that no other screened building claims — usually a site entrance, but check the outline on the plan below before relying on the street number.

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
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 879 ft of exterior wall, and across 9 residential floors the building carries 7,431 ft of it in total, divided among the 176 homes this screen estimates.
Its plate is elongated at 0.34: 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 19.6 homes per floor, repeated on every residential floor, since this building's outline does not change as it rises.
Why 918 17th St scores 97 out of 100
Daylight efficiency 100, Interior depth 100, Scale 100, Finance 78 — each out of 100, then weighted.
Score components for 918 17th St. Points are the subscore times its weight.
| Component | Subscore | Weight | Points |

| Financeremaining gap is 13% of conversion cost, scored from 60% down to 0% | 78 | 15% | 11.7 |
Most of what it earns comes from daylight efficiency, and what holds it back most is finance, at 78 out of 100: remaining gap is 13% of conversion cost, scored from 60% down to 0%.
What the conversion would cost
$360 per square foot all-in across 165,233 sq ft of converted floor, or $59.5M in total — about $338K for each of the 176 homes.
All-in cost per square foot for 918 17th 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 circulation and service area that earns nothing directly. Against it the model sets a completed value of $236K a home, which for 176 homes is $41.5M.
What would have to be true
A $17.9M gap before any grant, $7.9M after the modeled one. The smallest single change that would close it: average unit size 16% down.
The shortfall before any grant is $17.9M. Closing it from the value side means each of the 176 homes finishing at $338K rather than the $236K the model assumes — 43% more. Closing it from the cost side means getting all-in cost down from $360 to $251 per square foot.
A modeled RESIDE grant of $10.0M moves that threshold to $281K a home. That is still above the $236K assumed, leaving $7.9M uncovered, which is why the grant does not unlock this one.
Nor do all four levers have to move. For 918 17th St, one alone would close the gap at:

Within CBD and the D-TD zone
1st of 74 in CBD, 1st of 20 zoned D-TD — the comparison that shares its rules, rents and streets.
Denver places 74 of the screened buildings in CBD. 918 17th St ranks 1st of them against a median score of 71, the top score in the group. 38 score 70 or more, their median deepest interior point is 57 ft from a facade against this building’s 31 ft, and together they would hold an estimated 33,455 homes.
20 of the screened buildings are zoned D-TD. 918 17th St ranks 1st of them against a median score of 69, the top score in the group. 10 score 70 or more, their median deepest interior point is 57 ft from a facade against this building’s 31 ft, and together they would hold an estimated 8,565 homes.
Its nearest match in size: 1250 14th St
The screened building closest to 918 17th St in converted floor area is 1250 14th St: 161,849 sq ft over 11 stories, against 165,233 sq ft over 10 here.
918 17th St scores 97 to its 80, and with the size held roughly equal most of that lead comes from interior depth: 100 out of 100 here, 72 there (deepest interior point 51 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 1,800 ft apart.
Would it qualify for a RESIDE Act grant?
The model awards 918 17th 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.
