951 16th St

951 16th 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. 951 16th 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 70%. The shading is daylight, darkest at the windows and gone 35 ft in. The hatched area is windowless core: 9,044 sq ft per typical floor that must be renovated but can never be rented as an apartment. The dimension marks the deepest interior point, 59 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: 9,044 sq ft on the floor the screen scores, and 63,310 sq ft over 8 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 8 residential floors this building carries 63,310 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

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

The typical floor has 772 ft of exterior wall, and across 8 residential floors the building carries 5,580 ft of it in total, divided among the 161 homes this screen estimates.

Its plate is moderately compact at 0.64: 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 20.1 homes per floor, repeated on every residential floor, since this building's outline does not change as it rises.

Why 951 16th St scores 61 out of 100

Daylight efficiency 61, Interior depth 52, Scale 100, Finance 36 — each out of 100, then weighted.

Score components for 951 16th St. Points are the subscore times its weight.

Component	Subscore	Weight	Points
Daylight efficiency71% of the floor area within 35 ft of a facade, scored from 40% up to 90%	61	45%	27.5
Interior depthdeepest interior point 59 ft from a facade, scored from 80 ft down to 40 ft	52	25%	13.1

Financeremaining gap is 38% of conversion cost, scored from 60% down to 0%	36	15%	5.4

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 215,015 sq ft of converted floor, or $77.4M in total — about $481K for each of the 161 homes.

All-in cost per square foot for 951 16th 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 63,310 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 161 homes is $38.0M.

What would have to be true

A $39.4M gap before any grant, $29.7M after the modeled one. The smallest single change that would close it: average unit size 43% down.

The shortfall before any grant is $39.4M. Closing it from the value side means each of the 161 homes finishing at $481K rather than the $236K the model assumes — 104% more. Closing it from the cost side means getting all-in cost down from $360 to $177 per square foot.

A modeled RESIDE grant of $9.7M moves that threshold to $421K a home. That is still above the $236K assumed, leaving $29.7M uncovered, which is why the grant does not unlock this one.

Nor do all four levers have to move. For 951 16th St, one alone would close the gap at:

How it compares in Greater Downtown Denver

951 16th St ranks 162nd of the 214 buildings screened here, against a median score of 72.

Its floor plate is better lit than 14% of them, and shallower than 47% of them at its deepest interior point. On size it is the 123rd 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 CBD and the D-TD zone

58th of 75 in CBD, 13th of 20 zoned D-TD — the comparison that shares its rules, rents and streets.

Denver places 75 of the screened buildings in CBD. 951 16th St ranks 58th of them against a median score of 71. 40 score 70 or more, their median deepest interior point is 56 ft from a facade against this building’s 59 ft, and together they would hold an estimated 33,698 homes. The group’s top scorer is 918 17th St, at 97.

20 of the screened buildings are zoned D-TD. 951 16th St ranks 13th of them against a median score of 69. 10 score 70 or more, their median deepest interior point is 57 ft from a facade against this building’s 59 ft, and together they would hold an estimated 8,599 homes. The group’s top scorer is 918 17th St, at 97.

Its nearest match in size: 820 16th St

The screened building closest to 951 16th St in converted floor area is 820 16th St: 213,352 sq ft over 10 stories, against 215,015 sq ft over 9 here.

951 16th St scores 61 to its 67, and with the size held roughly equal most of that shortfall comes from daylight efficiency: 61 out of 100 here, 78 there (79% of the floor area within 35 ft of a facade, scored from 40% up to 90%). On the money they sit in the same place: each falls short even with the modeled grant. The two stand about 400 ft apart.

Would it qualify for a RESIDE Act grant?

The model awards 951 16th St $9.7M, 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.
