TL;DR
Riverside: no local rent control, AB 1482 controls. The applicable CPI is the Riverside–San Bernardino–Ontario metro figure, distinct from LA. No general rental registry. Standard habitability enforcement.
The Inland Empire CPI distinction
Riverside falls into the Riverside–San Bernardino–Ontario CPI-U metro for AB 1482 purposes. This figure is published separately from the LA–Long Beach–Anaheim metro and tracks Inland Empire economics. The percentages diverge from year to year — using LA-metro CPI numbers on a Riverside unit is a defective rent increase notice.
State framework otherwise
AB 1482's 5% + local CPI cap, the 10% ceiling, just-cause after 12 months for covered units, SB 567 OMI/substantial-remodel rules — all apply normally. No local overlay.
Habitability and STRs
Code Enforcement under §1941.1 plus city housing code. STR registration required for short-term rentals.
