The City of Santa Ana has officially announced the maximum allowable rent increase under its Rent Stabilization and Just Cause Eviction Ordinance (Ordinance No. NS-3027). Starting September 1, 2026, through August 31, 2027, landlords can increase rent by a maximum of 2.87% for qualifying residential units and mobilehome spaces. Calculated strictly using a local formula capped at the lesser of 3% or 80% of the Consumer Price Index (CPI), this new cap is a slight increase from the previous year’s limit of 2.42%.
The enforcement of this cap introduces strict operational hurdles for property owners. Landlords are prohibited from enacting an increase unless the property is completely compliant with city codes, all required repairs are documented as complete, and the rental unit is accurately registered with the city. Furthermore, landlords are restricted to a single increase within any 12-month period and must issue an explicit written notice detailing tenant rights under the local law.

Is the Ordinance Actually Helping Housing Costs?
Local data indicates that while the Rent Stabilization Ordinance shields specific, existing tenants from sudden price spikes, it is not lowering the broader cost of housing across Santa Ana. Since the law primarily applies to older multi-family structures built before February 1, 1995, a large portion of the city’s housing stock remains entirely unaffected.
Market metrics show that overall average asking rents in Santa Ana have historically stayed high, driven by standard supply-and-demand metrics rather than legislative caps. To prevent landlords from navigating around these price limits, the Santa Ana City Council recently had to pass a secondary ordinance on March 3, 2026, banning the use of algorithmic rent-setting software. This secondary intervention highlights that landlords continue to maximize market rates where gaps exist, proving that rent control acts more as a localized safety net for specific individuals than a tool to lower market-wide housing costs.
Southern California Rental Market Trends
The implementation of this cap comes at a fascinating time, as broader Southern California housing trends are shifting without the help of government intervention. According to recent market reports, landlords trimmed rents in 60% of Southern California cities. A cooling regional economy, stagnant population growth, and a modest local construction boom have collectively driven up multifamily vacancy rates…
