We pull it together and make it readable, so buyers, sellers, and agents can have the same conversation using the same facts.
Philadelphia keeps detailed records on every property: violations, permits, tax history, complaints, deed transfers. But that information is scattered across a half-dozen city databases, written in bureaucratic shorthand, and practically invisible to the people who need it most: the ones about to make a six-figure decision.
Flagstone was built to fix that.
We pull official city records into a single, plain-English report that anyone can understand, whether you're a first-time buyer, a seasoned investor, a real estate agent, or an attorney reviewing a deal. No jargon. No guesswork. The clearest picture available, typically in under a minute.
In most Philadelphia property transactions, there's an information gap. Sellers know the history of their property. Agents know which questions to ask and which to skip. But buyers? They're expected to spend hundreds of thousands of dollars on a property whose violation history, permit record, tax status, and neighborhood patterns they've never seen.
The information exists. It's public. It's free. But it's buried across L&I's eCLIPSE system, OPA's property search, the city's 311 portal, the deed registry, FEMA flood maps, and police incident data, each with its own interface, its own shorthand, and no connection to the others.
A motivated buyer might spend three or four hours piecing it together. Most don't. They skip it entirely and hope their agent or inspector catches everything. Sometimes they do. Sometimes the new owner discovers unpermitted basement work, an open code violation, or a tax lien that followed the property, not the seller, to settlement.
We believe no one should close on a property without knowing what the city already knows about it.
Real estate transactions work best when both sides have the same information. When a buyer can see the same violation history, permit record, and tax status that a seller already knows, the conversation changes. It becomes a negotiation between equals, not a test of who did more homework.
Philadelphia publishes property data across multiple city systems. But "public" doesn't mean "accessible." If it takes a real estate professional to navigate L&I's eCLIPSE portal, or to know that an expired permit doesn't always mean a problem, then that information is public in name only. We translate city records into language anyone can act on.
The buyer has their Zillow listing. The seller has their disclosure form. The agent has their MLS sheet. The attorney has their title search. Everyone's working from different documents with different data. Flagstone gives everyone the same page to look at: one report, drawn from official city and federal sources, that becomes one shared reference for the entire transaction.
We don't cover the whole country. We cover Philadelphia, deeply. We know what a CMX-2 zoning designation means for your renovation plans. We know that a 2019 permit closure on a 1925 rowhouse is worth a closer look. We know what a cluster of 311 complaints on your block actually signals. National tools can't tell you that. We can.
We're not here to tell you whether to buy a property. We're here to make sure you know what you're buying. A Flagstone report doesn't replace your inspector, your attorney, or your own judgment. It gives all of them, and you, the same foundation of facts to work from.

Philadelphia has one of the most complex municipal record systems of any major U.S. city. L&I manages violations and permits through eCLIPSE. OPA handles assessments and ownership. The Revenue Department tracks tax delinquency. PhilaDox holds deed records. 311 handles service requests. FEMA maps the flood zones. None of these systems talk to each other.
For a city where the median home price has risen significantly in recent years, and where entire neighborhoods are transforming block by block, that fragmentation is a real problem. Buyers making the biggest financial decision of their lives are doing it with incomplete information, not because the data doesn't exist, but because it's too scattered and too opaque to access practically.
We started with Philadelphia because this is where the problem is sharpest and where we can go deepest. Every data source, every risk signal, every line of our analysis is calibrated for how property works in this specific city. That's not a limitation. It's the whole point.
Flagstone is a small, local team focused on one thing: making Philadelphia's property records useful to the people who need them.
