County outlines are regional context. Use parcel attributes and agency records to verify jurisdiction.
The basemap is OpenStreetMap. Parcel shapes, TRPA’s regional boundary, South Lake Tahoe’s city boundary, and optional district layers are requested from TRPA’s public GIS services.
TRPA records are read from its public Permit Records service. The initial view requests the 100 most recently filed records. This is a limited window, not a complete permit inventory or a live construction count. Multiple records can share a parcel.
Map markers identify a parcel’s bounding-box center, not a construction footprint. Selected parcel outlines retain the geometry returned by TRPA. Map records may lag the agency’s permit system.
The county overview layer is derived from a 1:2,000,000-scale source. It is unsuitable for property-line decisions. Parcel shapes are reference GIS, not surveys. A boundary or record is not a determination of permit requirements or approval.
Local government portals are linked separately. Their records are not yet ingested. Truckee lies outside TRPA’s basin coverage; use Truckee’s permit portal for its records. Fire, utility, state, federal, or tribal authorities may also be relevant to a property; this directory is not an exhaustive list of approvals.
Searches are sent to TRPA; map tiles are requested from OpenStreetMap. This prototype has no accounts, analytics, submissions, or stored searches.
