1550 N Broadway

1550 N Broadway 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. 1550 N Broadway 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: 75% of the building’s floor area sits within daylight reach of a facade; the drawing shows its typical floor, where the share is 75%. The shading is daylight, darkest at the windows and gone 35 ft in. The hatched area is windowless core: 8,214 sq ft per typical floor that must be renovated but can never be rented as an apartment. The dimension marks the deepest interior point, 71 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: 8,214 sq ft on the floor the screen scores, and 169,799 sq ft over 23 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 23 residential floors this building carries 169,799 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

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

The typical floor has 866 ft of exterior wall, and across 23 residential floors the building carries 18,369 ft of it in total, divided among the 534 homes this screen estimates.

Its plate is moderately compact at 0.55: a squarish plan, with enough perimeter for a conventional double-loaded corridor. How window line and plate shape are measured.

At the model’s 750 sq ft average, the plan works out at about 23.2 homes per floor, repeated on every residential floor, since this building's outline does not change as it rises.

Why 1550 N Broadway scores 56 out of 100

Daylight efficiency 69, Interior depth 23, Scale 100, Finance 27 — each out of 100, then weighted.

Score components for 1550 N Broadway. Points are the subscore times its weight.

Financeremaining gap is 44% of conversion cost, scored from 60% down to 0%	27	15%	4.1

Most of what it earns comes from daylight efficiency, and what holds it back most is interior depth, at 23 out of 100: deepest interior point 71 ft from a facade, scored from 80 ft down to 40 ft.

What the conversion would cost

$360 per square foot all-in across 670,843 sq ft of converted floor, or $241.5M in total — about $452K for each of the 534 homes.

All-in cost per square foot for 1550 N Broadway: 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 169,799 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 534 homes is $126.0M.

What would have to be true

A $115.5M gap before any grant, $105.5M after the modeled one. The smallest single change that would close it: average unit size 46% down.

The shortfall before any grant is $115.5M. Closing it from the value side means each of the 534 homes finishing at $452K rather than the $236K the model assumes — 92% more. Closing it from the cost side means getting all-in cost down from $360 to $188 per square foot.

A modeled RESIDE grant of $10.0M moves that threshold to $434K a home. That is still above the $236K assumed, leaving $105.5M uncovered, which is why the grant does not unlock this one.

Nor do all four levers have to move. For 1550 N Broadway, one alone would close the gap at:

How it compares in Greater Downtown Denver

1550 N Broadway ranks 180th of the 214 buildings screened here, against a median score of 72.

Its floor plate is better lit than 27% of them, and shallower than 10% of them at its deepest interior point. On size it is the 33rd 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 D-C zone

39th of 41 in North Capitol Hill, 64th of 72 zoned D-C — the comparison that shares its rules, rents and streets.

Denver places 41 of the screened buildings in North Capitol Hill. 1550 N Broadway ranks 39th 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 71 ft, and together they would hold an estimated 8,820 homes. The group’s top scorer is 1776 N Grant St, at 97.

72 of the screened buildings are zoned D-C. 1550 N Broadway ranks 64th of them against a median score of 73. 39 score 70 or more, their median deepest interior point is 57 ft from a facade against this building’s 71 ft, and together they would hold an estimated 32,881 homes. The group’s top scorer is 721 19th St, at 95.

Its nearest match in size: 2001 16th St

The screened building closest to 1550 N Broadway in converted floor area is 2001 16th St: 648,985 sq ft over 22 stories, against 670,843 sq ft over 24 here.

The two land within a few points of each other — 56 here, 58 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 6,700 ft apart.

Would it qualify for a RESIDE Act grant?

The model awards 1550 N Broadway $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.
