Which buildings could meet the RESIDE Act's vacant-and-abandoned test

The RESIDE Act pays to convert only “vacant and abandoned” buildings, a term the law defines narrowly. Here is the test, and how many of the buildings screened on this site have public records that could meet it.

What the law requires

The RESIDE Act authorizes HUD grants to convert a “vacant and abandoned building” into attainable housing. The definition has two parts. The building must have been built for use as a warehouse, factory, mall, strip mall, hotel, or another industrial or commercial use, which covers office buildings. And it must meet one of two conditions. Either a code enforcement inspection found it unsafe, at least 90 days have passed since the owner was notified of the deficiencies, and the owner took no corrective action. Or it is subject to court-ordered receivership or nuisance abatement related to abandonment, or otherwise meets the state’s legal definition of abandoned property.

An office building with a high vacancy rate, or even no tenants at all, meets neither condition on that fact alone. The first condition turns on an unsafe finding the owner has not fixed, the second on a court or state-law finding of abandonment.

How many screened buildings could meet the test

Each city's unsafe-building cases are matched to the screened footprints they fall in, or within 15 feet of.

Downtown San Jose

San Jose does not publish its code enforcement cases as open data. The test cannot be checked for Downtown San Jose.

Greater Downtown Denver

Denver does not publish its building code enforcement or neglected and derelict building cases as open data. The test cannot be checked for Greater Downtown Denver.

Center City Philadelphia

As of November 3, 2026, 1 of the 100 buildings screened in Center City Philadelphia has an open unsafe-building case at least 90 days old, a possible match for the first prong that would need checking in the city's file. That building is 1625 Market St. Source: Philadelphia Department of Licenses and Inspections, unsafe and imminently dangerous structures.

Downtown Boston

As of November 3, 2026, none of the 96 buildings screened in Downtown Boston has an open unsafe-building case at least 90 days old. 7 had unsafe findings that were later resolved. Source: City of Boston Inspectional Services, Building and Property Violations (unsafe-structure codes, 780 CMR 116 and 121).

Downtown San Francisco

As of November 3, 2026, none of the 205 buildings screened in Downtown San Francisco has an open unsafe-building case at least 90 days old. Source: San Francisco Department of Building Inspection, Notices of Violation citing an unsafe or vacant building.

No record does not mean ineligible. Receivership, nuisance abatement and state-law abandonment are recorded in court files that none of these cities publishes as data, and open data can lag or omit a city’s own findings. A building shown here without a record is unconfirmed. A city applying for a grant would document the test for each building it proposes.

How this is checked

Philadelphia’s Department of Licenses and Inspections publishes its open unsafe and imminently dangerous structure cases with the violation date. Boston’s Inspectional Services publishes building violations, filtered here to the state building code’s unsafe-structure sections (780 CMR 116 and 121); that dataset gives only the date of a case’s latest status, so the 90-day count runs from that date and can only understate a case’s age. San Francisco’s Department of Building Inspection publishes its notices of violation as free text, filtered here to items citing an unsafe or dangerous building; items about vacancy alone are left out, because vacancy is not a finding that a building is unsafe. Denver and San Jose do not publish code enforcement cases as open data.

A building is listed as a possible match when it has a case that is still open and dated at least 90 days before the check date. That is not proof the first prong is met. The law counts 90 days from when the owner was notified and requires that no corrective action was taken. A case’s violation or status date is not its notice date, and an open case does not show whether anything was fixed. Both are in the city’s file, which a city applying for a grant would check.

Questions

Which buildings qualify for a RESIDE Act grant?

Only a vacant and abandoned building: one built for use as a warehouse, factory, mall, strip mall, hotel or other industrial or commercial use that either (i) a code enforcement inspection found unsafe, with at least 90 days since the owner was notified and no corrective action, or (ii) is in court-ordered receivership or nuisance abatement related to abandonment, or meets a state-law definition of abandoned property. A building that is merely empty does not qualify.

Does an empty office building qualify?

Not on vacancy alone. It must also meet one of the two prongs above. Across the buildings this site screened in cities that publish unsafe-building records, 1 of 401 has an open unsafe case at least 90 days old, a possible match for the first prong that still needs verifying in the city's file.

How many buildings in Downtown San Jose could meet the test?

San Jose does not publish its code enforcement cases as open data. The test cannot be checked for Downtown San Jose.

How many buildings in Greater Downtown Denver could meet the test?

Denver does not publish its building code enforcement or neglected and derelict building cases as open data. The test cannot be checked for Greater Downtown Denver.

How many buildings in Center City Philadelphia could meet the test?

As of November 3, 2026, 1 of the 100 buildings screened in Center City Philadelphia has an open unsafe-building case at least 90 days old, a possible match for the first prong that would need checking in the city's file.

How many buildings in Downtown Boston could meet the test?

As of November 3, 2026, none of the 96 buildings screened in Downtown Boston has an open unsafe-building case at least 90 days old. 7 had unsafe findings that were later resolved.

How many buildings in Downtown San Francisco could meet the test?

As of November 3, 2026, none of the 205 buildings screened in Downtown San Francisco has an open unsafe-building case at least 90 days old.

Does a building with no record fail the test?

No. It is unconfirmed. Receivership, nuisance abatement and state-law abandonment are in court records that none of these cities publishes as data, and a city may have a finding its open data does not show. A city applying for a grant would document the test itself.
