An unsafe building isn't only the owner's problem — a compromised structure, an open vacant property, or a sudden demolition affects everyone on the block. Philadelphia records these hazards publicly. Here's how to find them, how to read them, and how to report one near you.
Several kinds of public record flag an unsafe building in Philadelphia:
The distinction that matters most is open vs. resolved: a closed, corrected issue is a very different signal than one still outstanding.
These records are tied to specific addresses, so you can check a property directly. Our guide to looking up code violations is the place to start; read the results alongside the property's permit history for context. A cluster of open violations, an unsafe-structure finding, and a nearby demolition together tell a story no single record does.
By the time an unsafe building makes the news, its public record usually saw it coming. The information was there — just not in front of the people living next to it.
Report unsafe structures to L&I; non-emergency property concerns can also go through 311. If a building is an immediate threat — a partial collapse, falling masonry, an open vacant structure children can get into — treat it as an emergency, not a routine complaint. Include the address, what you observed, and photos with dates if you can.
The danger of unsafe buildings is that they degrade quietly until something happens. BlockWatcher watches your address, block, or district for new violations, unsafe-structure findings, and demolitions, and emails you when they post — turning a scattered feed into an early warning. See why every block needs a watcher and reading a neighborhood before it changes.
The city publishes L&I violations, unsafe-structure findings, and demolition activity tied to addresses. Look these up by property to see whether a building near you has been flagged and whether the issue is open or resolved.
Report unsafe structures to L&I; non-emergency concerns can go through 311. If a building is an immediate threat, treat it as an emergency.
Vacant, unmaintained buildings more often accumulate open violations and structural problems and can affect the safety of nearby properties. Their public records are how that risk becomes visible.
It's the city's classification for a structure considered an immediate hazard, which can lead to emergency stabilization or demolition — the kind of event worth knowing about right away.
