Lupa PoolFind — Unpermitted Pool Detection from Public Aerial Imagery
Satellite-based detection of swimming pools that were never permitted or never added to the tax roll. Cross-referenced against permit history and assessment records, delivered as a ranked list of assessment-gap leads for your audit team.
What Lupa detects
- Unpermitted pools — physical pool present on the parcel with no matching permit on file.
- Permitted but unassessed — permit was issued, but the pool never made it to the tax roll.
- Pool cages and screen enclosures — common in Florida, frequently missed in assessment.
- Above-ground vs. in-ground classification — important for jurisdictions that assess them differently or exempt above-ground units.
How it works
1. Aerial scan
Lupa processes publicly available aerial imagery (NAIP and county-flown sources) to identify pool footprints across every parcel in scope. Each detection includes a confidence score, type classification, and parcel ID.
2. Cross-reference
Each detection is matched against the parcel's permit history and current tax roll record. The output separates: detected + permitted + assessed (no action), detected + permitted + unassessed (review), and detected + no permit (priority).
3. Deliver
Findings arrive as a ranked lead list with parcel ID, owner name, detection confidence, permit status, and assessment status. Direct citation links let your audit team verify against the public source records before any outreach.
Florida note: §193.092 and revenue caps
Florida statute §193.092 limits back-assessment recovery on parcels where a permit was issued, which materially affects revenue projections on permitted-but-unassessed cases. Lupa surfaces unpermitted detections separately so your team can prioritize the cases where the §193.092 cap does not apply.
Who this is built for
- County property appraisers running periodic improvement audits across high-pool-density jurisdictions.
- Municipal assessors recovering assessment gaps in residential portfolios.
- State revenue agencies evaluating cross-county compliance program design.
Frequently asked questions
How does satellite pool detection work?
Public aerial imagery (NAIP and equivalent county-flown sources) is processed parcel-by-parcel to identify swimming pool footprints. Each detection is cross-referenced against the parcel's permit history and tax roll record.
What's the difference between pool detection and a permit audit?
A permit audit only sees pools that someone applied for. Pool detection sees pools that physically exist on the parcel — including ones built without a permit. The combination is what surfaces assessment gaps.
Does Lupa charge for imagery?
No. Lupa relies on publicly available aerial imagery (NAIP, county GIS programs, and similar). No per-image cost or commercial satellite subscription required.
How does Florida §193.092 affect this?
It caps back-assessment recovery on permitted parcels. Lupa surfaces unpermitted detections separately so your team can focus on cases where the cap does not apply.
