This building's conversion pencils at default assumptions without any subsidy.
Every floor carries 3,198 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 15,989 sq ft of cost carrying no revenue.
Part of this building is already homes. San Jose's rental housing and condominium records list 130 condominiums here, fewer than half the homes this model estimates the building could hold. The figures here treat the whole building as convertible, so read them as an upper bound and check which floors are already housing.
Read with caution. This footprint carries 16 street addresses across 54,922 sq ft, which usually means the city’s GIS has merged a block or complex into a single polygon rather than describing one convertible building.

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 1,909 ft of exterior wall, and across 5 residential floors the building carries 9,547 ft of it in total, divided among the 275 homes this screen estimates.
Its plate is highly articulated at 0.19: a long, notched or wing-shaped outline with far more facade than its area needs — wasteful as an office envelope, and close to ideal for apartments. How window line and plate shape are measured.
At the model’s 750 sq ft average, the plan works out at about 55.0 homes per floor, repeated on every residential floor, since this building's outline does not change as it rises.

Score components for 111 Paseo De San Antonio. Points are the subscore times its weight.

| Financecompleted value covers conversion cost with 14% to spare, which tops out the component | 100 | 15% | 15.0 |
Most of what it earns comes from daylight efficiency, and what holds it back most is interior depth, at 84 out of 100: deepest interior point 46 ft from a facade, scored from 80 ft down to 40 ft.
What the conversion would cost
$405 per square foot all-in across 274,612 sq ft of converted floor, or $111.2M in total — about $404K for each of the 275 homes.
All-in cost per square foot for 111 Paseo De San Antonio: 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 15,989 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 275 homes is $116.9M.
What would have to be true
This one already clears the bar. The question is how much room it has before it stops.
At $425K a home, completed value covers the $111.2M of work with $5.7M to spare. Value per home would have to fall to $404K — 5% below the assumption — before the conversion stopped penciling, or all-in cost would have to rise from $405 to $426 per square foot. Neither is a wide margin in a market that moves, but this building does not need a grant to work.
Each of these, moved on its own, would be enough to undo that for 111 Paseo De San Antonio:

Would it qualify for a RESIDE Act grant?
The model awards 111 Paseo De San Antonio $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.
