1300 N Fox St

1300 N Fox 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. 1300 N Fox 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: 71% of the building’s floor area sits within daylight reach of a facade; the drawing shows its typical floor, where the share is 66%. The shading is daylight, darkest at the windows and gone 35 ft in. The hatched area is windowless core: 14,229 sq ft per typical floor that must be renovated but can never be rented as an apartment. The dimension marks the deepest interior point, 62 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: 14,229 sq ft on the floor the screen scores, and 34,165 sq ft over 5 residential floors. 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 34,165 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

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

The typical floor has 959 ft of exterior wall, and across 5 residential floors the building carries 3,188 ft of it in total, divided among the 88 homes this screen estimates.

Its plate is moderately compact at 0.58: 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 17.6 homes per floor, repeated on every residential floor, since this building's outline does not change as it rises.

Why 1300 N Fox St scores 53 out of 100

Daylight efficiency 62, Interior depth 45, Scale 59, Finance 36 — each out of 100, then weighted.

Score components for 1300 N Fox St. Points are the subscore times its weight.

Most of what it earns comes from daylight efficiency, and what holds it back most is finance, at 36 out of 100: remaining gap is 38% of conversion cost, scored from 60% down to 0%.

What the conversion would cost

$360 per square foot all-in across 117,000 sq ft of converted floor, or $42.1M in total — about $479K for each of the 88 homes.

All-in cost per square foot for 1300 N Fox 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 34,165 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 88 homes is $20.8M.

What would have to be true

A $21.4M gap before any grant, $16.1M after the modeled one. The smallest single change that would close it: average unit size 38% down.

The shortfall before any grant is $21.4M. Closing it from the value side means each of the 88 homes finishing at $479K rather than the $236K the model assumes — 103% more. Closing it from the cost side means getting all-in cost down from $360 to $178 per square foot.

A modeled RESIDE grant of $5.3M moves that threshold to $419K a home. That is still above the $236K assumed, leaving $16.1M uncovered, which is why the grant does not unlock this one.

Nor do all four levers have to move. For 1300 N Fox St, one alone would close the gap at:

How it compares in Greater Downtown Denver

1300 N Fox St ranks 187th of the 214 buildings screened here, against a median score of 72.

Its floor plate is better lit than 15% of them, and shallower than 30% of them at its deepest interior point. On size it is the 169th 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 Civic Center and the D-GT zone

16th of 23 in Civic Center, 14th of 15 zoned D-GT — the comparison that shares its rules, rents and streets.

Denver places 23 of the screened buildings in Civic Center. 1300 N Fox St ranks 16th of them against a median score of 67. 10 score 70 or more, their median deepest interior point is 62 ft from a facade against this building’s 62 ft, and together they would hold an estimated 5,064 homes. The group’s top scorer is 1314 N Elati St, at 92.

15 of the screened buildings are zoned D-GT. 1300 N Fox St ranks 14th of them against a median score of 76. 8 score 70 or more, their median deepest interior point is 54 ft from a facade against this building’s 62 ft, and together they would hold an estimated 2,397 homes. The group’s top scorer is 1314 N Elati St, at 92.

Its nearest match in size: 1621 18th St

The screened building closest to 1300 N Fox St in converted floor area is 1621 18th St: 113,796 sq ft over 6 stories, against 117,000 sq ft over 6 here.

1300 N Fox St scores 53 to its 60, and with the size held roughly equal most of that shortfall comes from interior depth: 45 out of 100 here, 61 there (deepest interior point 56 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 6,000 ft apart.

Would it qualify for a RESIDE Act grant?

The model awards 1300 N Fox St $5.3M, 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.
