A violation is the city telling you a filing was missed. PropCog works from the other end: the filing schedule first, the violation as a backstop.
City, county and state feeds sync on the source’s own schedule. No scraping, no middlemen, no stale spreadsheets.
Each building carries its own deadline clocks: the laws that apply, when they bite, and what they cost if missed.
New violations and code cases reach the right people instantly or as a daily digest, routed by building, group or role.
Per-user roles, building-level scoping and property groups keep admins in control of who sees and hears what.
Sync portfolios straight from AppFolio and Buildium, import a CSV, or add buildings one address at a time.
Records export cleanly. Work with any expeditor or attorney you want, whenever a case does land.
Type addresses, import a CSV, or sync your whole portfolio from AppFolio or Buildium.
Agency feeds stream in on the source’s own schedule: violations, code cases, permits and deadline clocks per building.
Instant alerts or a daily digest, routed to the right people, before the certified mail shows up.
Type an address and PropCog draws the record the city and county keep on it: what the building is, what is open against it, and what falls due next. Every figure is sourced and dated.
PropCog and the two market sites are tools we built on the Polywei platform. Your workspace holds your own buildings; Polywei joins them to the public record, so you can look up any building, see what it owes and when, and put reminders and compliance tasks on autopilot instead of reacting to letters.
Your portfolio, synced from your own systems into your Polywei workspace.
Every address joined to the agency feeds that mention it, kept current on the source’s schedule.
Calendars, reminders and compliance tasks run on their own, so nothing waits for a letter.
Your first property is free, no card required, and every paid plan begins with a free trial. Pick the market where your buildings are and your workspace is ready in a minute.
No ads, no trackers, no third-party analytics. The app holds the sign-in token and the account’s own data, and nothing else.
Official public records only. New York streams from NYC Open Data (DOB, HPD, ECB, OATH, DEP, DOF); South Florida syncs county and municipal systems across Miami-Dade, Broward and Palm Beach plus state DBPR records. Every figure is sourced and dated.

Sync it straight from AppFolio or Buildium, import a CSV, or add buildings one address at a time. Records export cleanly whenever you need them.
The sign-in token and the account’s own data: your email and user id, the addresses you save, and a device token so alerts can be delivered. No ads, no trackers, no third-party analytics. Location is asked once to pick a default market and is never stored.
