1790 N Logan St

1790 N Logan St and the 1,000 ft of Greater Downtown Denver around it. The streets are drawn at the width of the right-of-way they run down, sidewalks included, and named, and every building on these blocks is drawn. What is left open and stippled is neither: a surface lot, a plaza or a vacant parcel. The screened buildings are colored by the ramp above, the same one the district map uses, carry their score, and each is a link to its own page. Each casts a shadow as long as its measured height lets it, so towers stand out from the low buildings around them; the unscreened buildings have no measured height and cast none. 1790 N Logan St is outlined in its own score color at the outline it covers at ground level. Dashed inside it is the typical floor, the one the floor-plate figure below draws, because this building steps back as it rises. Its windowless core is hatched. The inset places it among every building the screen covers.

Typical floor plan: 100% of the building’s floor area sits within daylight reach of a facade; the drawing shows its typical floor, where the share is 99%. The shading is daylight, darkest at the windows and gone 35 ft in. The hatched area is windowless core: 153 sq ft per typical floor that must be renovated but can never be rented as an apartment. The dimension marks the deepest interior point, 40 ft from the nearest window. A–A is where the section beside it is cut.

Section A–A: cut across the depth of the plate, through the middle of the core. Daylight reaches 35 ft in from every facade, fading as it goes, and the hatched stripe left between the lit edges is floor that gets converted and can never be rented: 153 sq ft on the floor the screen scores, and 153 sq ft over 5 residential floors. The steps are where the building sets back as it rises. The shaded ground floor is converted like the rest and counted as no homes.

This building does not pencil at default assumptions, even with a modeled RESIDE Act grant.

Across its 5 residential floors this building carries 153 sq ft of windowless core — area that must be gutted, re-plumbed and sprinklered but can never be rented as an apartment.

The plan: window line, shape and floor rhythm

53 ft of exterior wall for each home the screen estimates — enough for two- and three-bedroom homes across the plan.

The typical floor has 1,200 ft of exterior wall, and across 5 residential floors the building carries 3,571 ft of it in total, divided among the 67 homes this screen estimates.

Its plate is highly articulated at 0.23: a long, notched or wing-shaped outline with far more facade than its area needs — wasteful as an office envelope, and close to ideal for apartments. How window line and plate shape are measured.

At the model’s 750 sq ft average, the plan works out at about 13.4 homes per floor, repeated on every residential floor, since this building's outline does not change as it rises.

Why 1790 N Logan St scores 89 out of 100

Daylight efficiency 100, Interior depth 100, Scale 45, Finance 79 — each out of 100, then weighted.

Score components for 1790 N Logan St. Points are the subscore times its weight.

Financeremaining gap is 13% of conversion cost, scored from 60% down to 0%	79	15%	11.9

Most of what it earns comes from daylight efficiency, and what holds it back most is scale, at 45 out of 100: 67 estimated homes, scored from 0 up to 150.

What the conversion would cost

$360 per square foot all-in across 62,995 sq ft of converted floor, or $22.7M in total — about $338K for each of the 67 homes.

All-in cost per square foot for 1790 N Logan 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 153 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 67 homes is $15.8M.

What would have to be true

A $6.9M gap before any grant, $2.8M after the modeled one. The smallest single change that would close it: average unit size 13% down.

The shortfall before any grant is $6.9M. Closing it from the value side means each of the 67 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 $4.0M moves that threshold to $278K a home. That is still above the $236K assumed, leaving $2.8M uncovered, which is why the grant does not unlock this one.

Nor do all four levers have to move. For 1790 N Logan St, one alone would close the gap at:

Within North Capitol Hill and the C-MX-12 zone

10th of 41 in North Capitol Hill, 4th of 16 zoned C-MX-12 — the comparison that shares its rules, rents and streets.

Denver places 41 of the screened buildings in North Capitol Hill. 1790 N Logan St ranks 10th 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 40 ft, and together they would hold an estimated 8,820 homes. The group’s top scorer is 1776 N Grant St, at 97.

16 of the screened buildings are zoned C-MX-12. 1790 N Logan St ranks 4th of them against a median score of 85. 13 score 70 or more, their median deepest interior point is 44 ft from a facade against this building’s 40 ft, and together they would hold an estimated 2,011 homes.

Its nearest match in size: 201 E Colfax Ave

The screened building closest to 1790 N Logan St in converted floor area is 201 E Colfax Ave: 64,073 sq ft over 6 stories, against 62,995 sq ft over 6 here.

1790 N Logan St scores 89 to its 71, and with the size held roughly equal most of that lead comes from interior depth: 100 out of 100 here, 62 there (deepest interior point 55 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 1,700 ft apart.

Would it qualify for a RESIDE Act grant?

The model awards 1790 N Logan St $4.0M, 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.
