Vacancy is reported before it is recorded
The earliest public signal that a building is empty in Cleveland is not a filing by the city. It is a resident calling 311. 16,060 vacant-property reports came in since January 2024 — the largest housing-related 311 category the city has, behind only trash and recycling across all categories.
That makes it early and noisy in equal measure. A 311 report is somebody's observation, not an inspection, and one report is a data point rather than a finding. A cluster of them on a block, sustained over months, is something else.
The second signal: illegal dumping
9,572 illegal-dumping reports over the same window. Dumping tracks vacancy closely for an obvious reason — a lot nobody is watching is a lot somebody will use — and it is often reported before the vacancy itself is.
The same five neighbourhoods
Vacancy reports concentrate in Broadway–Slavic Village (2,281), Glenville (1,696), Union–Miles (1,249), Mount Pleasant (1,085) and Collinwood–Nottingham (791).
Those are the same five neighbourhoods, in nearly the same order, that lead the city on condemnation. The two records are produced by different processes — one is residents calling, the other is inspectors filing — and they agree. Where two independent measures agree, the signal is stronger than either alone.
Reading the three together
- 311 vacancy reports are the earliest and the least reliable individually.
- Illegal dumping is the corroborating condition signal on the same ground.
- Condemnation is the city's own finding, filed late and worth the most.
A property carrying all three is telling a consistent story. One carrying only the first is telling you somebody made a phone call.
