How can our HOA stop Airbnb and short-term-rental parking abuse?

Quick answer. The single most effective control is owner-occupant verification combined with a per-resident monthly pass cap and manager approval for over-cap requests. Together they block the LLC-owned shell-units that operate as STRs and stop any unit from issuing 30+ guest passes a month. Add STR-pattern anomaly alerts (out-of-state plate clusters, weekend-only patterns) to give the board evidence for code enforcement.

Why STR parking abuse is so hard to stop

STR operators register units under shell LLCs so the resident roster looks legitimate. They generate dozens of QR guest passes per week and screenshot them to renters. They pressure the on-site manager into approving over-cap requests at midnight when new tenants arrive. The HOA's clipboard-and-spreadsheet system can't tell the difference between a legitimate guest visit and a $4,000/week vacation rental's Saturday turnover.

The five controls that actually work

1. Owner-occupant verification by mailed code. STR operators (especially absentee LLCs) can't intercept mail at a unit they don't actually live at — catches roughly 60% of unlicensed STRs.
2. Per-resident monthly pass cap with manager approval queue. Default cap of 15 passes/resident/month. STRs that issue 30+ passes a month go straight to the queue.
3. Plate-bound, anti-sharing passes. Screenshotting and sharing the QR code does nothing — different plate at the gate generates UNAUTHORIZED.
4. STR-pattern anomaly alerts. Board's email pings when a unit issues passes to 5+ different out-of-state plates in a 30-day window.
5. Watchlist with auto-fine. Plates with prior violations get automatic fines on next sighting; gate stays closed.

Most HOAs see pass abuse drop ~80% in the first 30 days.
