1575 N Sherman St

1575 N Sherman 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. 1575 N Sherman 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: 88% of the building’s floor area sits within daylight reach of a facade; the drawing shows its typical floor, where the share is 86%. The shading is daylight, darkest at the windows and gone 35 ft in. The hatched area is windowless core: 1,712 sq ft per typical floor that must be renovated but can never be rented as an apartment. The dimension marks the deepest interior point, 54 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: 1,712 sq ft on the floor the screen scores, and 12,530 sq ft over 10 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 10 residential floors this building carries 12,530 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

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 446 ft of exterior wall, and across 10 residential floors the building carries 3,971 ft of it in total, divided among the 96 homes this screen estimates.

Its plate is compact at 0.78: 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 9.6 homes per floor, repeated on every residential floor, since this building's outline does not change as it rises.

Why 1575 N Sherman St scores 78 out of 100

Daylight efficiency 96, Interior depth 65, Scale 64, Finance 61 — each out of 100, then weighted.

Score components for 1575 N Sherman St. Points are the subscore times its weight.

Financeremaining gap is 24% of conversion cost, scored from 60% down to 0%	61	15%	9.1

Most of what it earns comes from daylight efficiency, and what holds it back most is finance, at 61 out of 100: remaining gap is 24% of conversion cost, scored from 60% down to 0%.

What the conversion would cost

$360 per square foot all-in across 103,440 sq ft of converted floor, or $37.2M in total — about $388K for each of the 96 homes.

All-in cost per square foot for 1575 N Sherman 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 12,530 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 96 homes is $22.7M.

What would have to be true

A $14.6M gap before any grant, $8.8M after the modeled one. The smallest single change that would close it: average unit size 23% down.

The shortfall before any grant is $14.6M. Closing it from the value side means each of the 96 homes finishing at $388K rather than the $236K the model assumes — 64% more. Closing it from the cost side means getting all-in cost down from $360 to $219 per square foot.

A modeled RESIDE grant of $5.8M moves that threshold to $328K a home. That is still above the $236K assumed, leaving $8.8M uncovered, which is why the grant does not unlock this one.

Nor do all four levers have to move. For 1575 N Sherman St, one alone would close the gap at:

How it compares in Greater Downtown Denver

1575 N Sherman St ranks 84th of the 214 buildings screened here, against a median score of 72.

Its floor plate is better lit than 65% of them, and shallower than 57% of them at its deepest interior point. On size it is the 161st 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 North Capitol Hill and the C-MX-16 zone

27th of 41 in North Capitol Hill, 5th 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. 1575 N Sherman St ranks 27th 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 54 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. 1575 N Sherman St ranks 5th 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 54 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: 1711 19th St

The screened building closest to 1575 N Sherman St in converted floor area is 1711 19th St: 102,474 sq ft over 8 stories, against 103,440 sq ft over 11 here.

The two land within a few points of each other — 78 here, 79 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 6,100 ft apart.

Would it qualify for a RESIDE Act grant?

The model awards 1575 N Sherman St $5.8M, 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.
