FAQ
Common questions.
How does the LucidIQ score work?+−
LucidIQ combines verified tenant reviews (60% weight) with public data — violation counts, complaints, DOB filings, and zip-level crime — into a letter grade (A–F) and a 0-to-5 numeric score. A building with no open violations and strong reviews scores around 4.5.
Is Lucid Rents free?+−
Yes. Every building report, LucidIQ score, and tenant review is free — forever. We never sell tenant data and never run paid listings.
Where does the data come from?+−
Official city agencies (HPD, DOB, 311 for NYC; LAHD and REAP for LA; Chicago's Building Services and RLTO tracking; Miami-Dade Code Enforcement; Harris County Code for Houston) plus tenant-submitted reviews.
What is the Chicago RLTO?+−
The Residential Landlord & Tenant Ordinance sets Chicago-specific rules on security deposits, heat provision, repair timelines, and lease termination. We track RLTO violations per building.
How does Chicago's heat ordinance work?+−
Between September 15 and June 1, indoor temperature must reach 68°F daytime and 66°F overnight. Heat complaints filed with 311 show up on the building's record.
