Torrance data is refreshed by the city about quarterly and includes status and job value. Rancho Palos Verdes is checked daily, but its public search shows only permit type, address and filing date (no description, status or value). Hermosa Beach is checked daily from the city's public permit search. San Pedro and Wilmington come from City of LA (LADBS) open data, refreshed weekly, building permits only. Manhattan Beach is checked daily from the city's public permit search. Gardena comes from the city's monthly issued-permits report (about a month behind). Palos Verdes Estates, Rolling Hills, Rolling Hills Estates, Lomita (incl. Harbor Hills), Carson and Lawndale don't publish searchable permits; their leads come from LA County records (Fire plan checks, address requests, county referrals), which capture larger projects only. Property details: LA County Assessor. “Potential opportunity” lists trades that may want the lead: for projects still in plan review it includes the permitted work itself, since the contractor may not be chosen yet; once issued, only adjacent trades. Permit data is public record; contact homeowners in line with telemarketing rules (TCPA / Do Not Call). Saved leads are stored in this browser only.
