Is Lotorb a listing site like Zillow or Redfin?

No. Lotorb does not publish MLS listings, sale prices, or owner contact information. We focus on permit-derived property intelligence — renovation history, system ages, and upgrade opportunity signals.

What data sources does Lotorb use?

Municipal building permits, county assessor records, hazard datasets, utility territory signals, and local cost benchmarks. Coverage is strongest in Orange and Riverside County, California.

Can I look up building permits by address?

Yes. Lotorb normalizes permit records into address-level timelines. Search any California address to see whether we have documented roof, HVAC, solar, plumbing, or electrical permit events.
