190 N 3rd St and the 1,000 ft of Downtown San Jose 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. 190 N 3rd St is outlined in its own score color at the outline it covers at ground level. Its windowless core is hatched. The inset places it among every building the screen covers.
69 ftAA100 ftDaylit 78%Core 6,401 sq ft
Floor plan: 78% of each floor sits within daylight reach of a facade. The shading is daylight, darkest at the windows and gone 35 ft in. The hatched area is windowless core: 6,401 sq ft per floor that must be renovated but can never be rented as an apartment. The dimension marks the deepest interior point, 69 ft from the nearest window. A–A is where the section beside it is cut.
Ground floor · no homesWindowless coreDaylit6 floors50 ft
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: 6,401 sq ft on the floor the screen scores, and 32,006 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.

Every floor carries 6,401 sq ft of windowless core — area that must be gutted, seismically braced and sprinklered but can never be rented as an apartment. Across 5 residential floors that is 32,006 sq ft of cost carrying no revenue.

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 873 ft of exterior wall, and across 5 residential floors the building carries 4,363 ft of it in total, divided among the 123 homes this screen estimates.

Its plate is moderately compact at 0.49: 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 24.6 homes per floor, repeated on every residential floor, since this building's outline does not change as it rises.

Why 190 N 3rd St scores 69 out of 100

Daylight efficiency 77, Interior depth 28, Scale 82, Finance 100 — each out of 100, then weighted.

Score components for 190 N 3rd St. Points are the subscore times its weight.

Most of what it earns comes from daylight efficiency, and what holds it back most is interior depth, at 28 out of 100: deepest interior point 69 ft from a facade, scored from 80 ft down to 40 ft.

What the conversion would cost

$405 per square foot all-in across 147,414 sq ft of converted floor, or $59.7M in total — about $485K for each of the 123 homes.

All-in cost per square foot for 190 N 3rd St: base cost plus the code work a change of use triggers.

Base conversion cost$260/sq ft
Seismic retrofit (change of use)$45/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$405/sq ft

That cost is charged across every converted square foot, including the 32,006 sq ft of windowless core, which has to be gutted, seismically braced and sprinklered like the rest of the building and then earns nothing. Against it the model sets a completed value of $425K a home, which for 123 homes is $52.3M.

What would have to be true

A $7.4M gap before any grant, $48K after the modeled one. The smallest single change that would close it: completed value per home under 1% up.

The shortfall before any grant is $7.4M. Closing it from the value side means each of the 123 homes finishing at $485K rather than the $425K the model assumes — 14% more. Closing it from the cost side means getting all-in cost down from $405 to $355 per square foot.

A modeled RESIDE grant of $7.4M moves that threshold to $425K a home. That is still above the $425K assumed, leaving $48K uncovered, which is why the grant does not unlock this one.

Nor do all four levers have to move. For 190 N 3rd St, one alone would close the gap at:

How it compares in Downtown San Jose

190 N 3rd St ranks 39th of the 82 buildings screened here, against a median score of 64.

Its floor plate is better lit than 59% of them, and shallower than 46% of them at its deepest interior point. On size it is the 67th largest by estimated homes. The full survey of all 82 buildings ranks and maps every one of them, and the list by address links each to its own page.

Within the DC zone

33rd of 72 zoned DC — the comparison that shares its rules, rents and streets.

72 of the screened buildings are zoned DC. 190 N 3rd St ranks 33rd of them against a median score of 61. 31 score 70 or more, their median deepest interior point is 68 ft from a facade against this building’s 69 ft, and together they would hold an estimated 23,276 homes. The group’s top scorer is 1 Almaden Blvd, at 100.

Its nearest match in size: 100 E Santa Clara St

The screened building closest to 190 N 3rd St in converted floor area is 100 E Santa Clara St: 132,842 sq ft over 6 stories, against 147,414 sq ft over 6 here.

190 N 3rd St scores 69 to its 93, and with the size held roughly equal most of that shortfall comes from interior depth: 28 out of 100 here, 81 there (deepest interior point 48 ft from a facade, scored from 80 ft down to 40 ft). On the money they part ways: 100 E Santa Clara St pencils without a subsidy, while 190 N 3rd St falls short even with the modeled grant. The two stand about 1,200 ft apart.

Would it qualify for a RESIDE Act grant?

The model awards 190 N 3rd St $7.4M, 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.

This building does sit in census tract 06085501000, a 2018 designated Opportunity Zone, which Section 201 lets HUD favor — one of the few statutory priorities this screen can actually check.
