2101 Market St

2101 Market 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. 2101 Market 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: 90% of the building’s floor area sits within daylight reach of a facade; the drawing shows its typical floor, where the share is 87%. The shading is daylight, darkest at the windows and gone 35 ft in. The hatched area is windowless core: 5,578 sq ft per typical floor that must be renovated but can never be rented as an apartment. The dimension marks the deepest interior point, 61 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: 5,578 sq ft on the floor the screen scores, and 22,558 sq ft over 6 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 6 residential floors this building carries 22,558 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 1,336 ft of exterior wall, and across 6 residential floors the building carries 7,701 ft of it in total, divided among the 227 homes this screen estimates.

Its plate is elongated at 0.31: a slab or an L, which is why so much of the floor lies within reach of a window: the outline buys daylight that a square plan of the same area would not. How window line and plate shape are measured.

At the model’s 750 sq ft average, the plan works out at about 37.8 homes per floor. Its floors are not alike, though: the typical floor's deepest interior point is 61 ft from a facade, while its worst floor reaches 65 ft. The score follows the typical floor, so a podium that could not hold a bedroom does not by itself sink a slim tower above it — but it is there, and it is part of what would have to be drawn around.

Why 2101 Market St scores 80 out of 100

Daylight efficiency 100, Interior depth 46, Scale 100, Finance 58 — each out of 100, then weighted.

Score components for 2101 Market St. Points are the subscore times its weight.

Component	Subscore	Weight	Points
Daylight efficiency90% of the floor area within 35 ft of a facade, scored from 40% up to 90%	100	45%	45.0
Interior depthdeepest interior point 61 ft from a facade, scored from 80 ft down to 40 ft	46	25%	11.6
Scale227 estimated homes, scored from 0 up to 150	100	15%	15.0
Financeremaining gap is 25% of conversion cost, scored from 60% down to 0%	58	15%	8.7

Most of what it earns comes from daylight efficiency, and what holds it back most is interior depth, at 46 out of 100: deepest interior point 61 ft from a facade, scored from 80 ft down to 40 ft.

What the conversion would cost

$360 per square foot all-in across 235,459 sq ft of converted floor, or $84.8M in total — about $373K for each of the 227 homes.

All-in cost per square foot for 2101 Market 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 22,558 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 227 homes is $53.6M.

What would have to be true

A $31.2M gap before any grant, $21.2M after the modeled one. The smallest single change that would close it: average unit size 28% down.

The shortfall before any grant is $31.2M. Closing it from the value side means each of the 227 homes finishing at $373K rather than the $236K the model assumes — 58% more. Closing it from the cost side means getting all-in cost down from $360 to $228 per square foot.

A modeled RESIDE grant of $10.0M moves that threshold to $329K a home. That is still above the $236K assumed, leaving $21.2M uncovered, which is why the grant does not unlock this one.

Nor do all four levers have to move. For 2101 Market St, one alone would close the gap at:

How it compares in Greater Downtown Denver

2101 Market St ranks 76th of the 214 buildings screened here, against a median score of 72.

Its floor plate is better lit than 76% of them, and shallower than 36% of them at its deepest interior point. On size it is the 98th 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 Five Points

7th of 20 in Five Points — the comparison that shares its rules, rents and streets.

Denver places 20 of the screened buildings in Five Points. 2101 Market St ranks 7th of them against a median score of 68. 9 score 70 or more, their median deepest interior point is 61 ft from a facade against this building’s 61 ft, and together they would hold an estimated 5,122 homes. The group’s top scorer is 3355 Denargo St, at 90.

Its nearest match in size: 2900 N Fox St

The screened building closest to 2101 Market St in converted floor area is 2900 N Fox St: 237,608 sq ft over 8 stories, against 235,459 sq ft over 7 here.

2101 Market St scores 80 to its 58, and with the size held roughly equal most of that lead comes from daylight efficiency: 100 out of 100 here, 60 there (70% 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 1,700 ft apart.

Would it qualify for a RESIDE Act grant?

The model awards 2101 Market St $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.
