Does Irvine restrict short-term rentals (Airbnb / VRBO)?
Irvine does not run a short-term rental permit or registration program the way San Diego or Sacramento do. Instead, Zoning Code Chapter 3-25 prohibits rental of a dwelling unit for periods under 30 days across the city's residential zoning districts, and the city's code enforcement division treats a listed unhosted stay as a zoning violation from the first night. The city's own STR enforcement page states administrative fines can reach $1,500 per day once a notice of violation is issued and ignored — a materially higher exposure than the flat per-violation fines used by neighboring Orange County cities that instead license STRs.
