Houston's new short-term rental (STR) ordinance, effective Jan. 1, 2026, regulates rentals under 30 days, enforcing noise rules, taxes, and safety codes. Registrations start Aug. 1, costing $275 annually. STRs must display emergency contacts, complete human trafficking training, and cannot advertise as event spaces. Non-compliance fines range from $100 to $500 daily. Platforms like Airbnb must remove non-compliant listings within 10 days of city notice.
