Central OC: Santa Ana Bans Algorithmic Rent Software
Santa Ana just became one of the few cities in California to ban the rent-pricing software landlords use to synchronize increases.
Market Intel
📏 Price/SqFt: $715 (Tustin: $673 | Santa Ana: $602)
⏱️ Days on Market: 33 days (healthy pace with buyer choice)
📦 Active Listings: 1,012 homes (↑45 vs last week)
💰 List-to-Sale Ratio: 99.0% (competitive market near asking price)
What This Means: The Central Orange County market is entering a transitional phase characterized by rising inventory levels and a cautious but active buyer pool responding to mortgage rates in the low 6% range. While the regional Unsold Inventory Index remains at a relatively tight 3.8 months, the divergence between the high-velocity mid-tier segment and the slower luxury bracket suggests a move toward a more balanced environment. Sellers of turnkey properties continue to hold pricing power, but the overall increase in active listings across cities like Santa Ana and Costa Mesa provides buyers with the most leverage observed in the previous three spring cycles.

[Santa Ana] City Bans Rent Algorithm Software — A First for Central OC
Santa Ana's City Council formally approved an ordinance on March 12 prohibiting the use of algorithmic rent-setting software, targeting platforms that allow property managers to coordinate pricing in ways the city argues artificially inflates rents for residents. The ban directly affects multifamily property operations throughout the city, adding a new layer of municipal oversight to how landlords set and adjust rents. For renters in Santa Ana neighborhoods like the Lacy district and Downtown, the ordinance signals the city is willing to use technology regulation as a housing affordability tool. For landlords and multifamily investors, this is a compliance shift that will require reviewing current pricing tools and contracts with software vendors. Santa Ana joins a short list of cities nationally that have taken this step, making this week's vote a potential model for neighboring municipalities watching closely.
[Costa Mesa] Tenant Protection Ordinance Amendments Head to City Council Tuesday
Costa Mesa's City Council holds a public hearing tomorrow, March 17, on proposed amendments to its Tenant Protection Ordinance that could tighten the definition of "just cause" evictions and expand relocation assistance requirements for displaced renters. The hearing follows a broader review period in which housing advocates and landlord groups have offered competing interpretations of the ordinance's current language. If passed, the amendments would raise operational costs for property managers in Costa Mesa's high-density rental corridors, including Eastside Costa Mesa, where luxury rental stock is concentrated. The council is also reviewing concurrent Housing Element zoning and fee amendments that could update impact fees for new construction, adding further complexity to the development pipeline in the city.
[Tustin] Public Input Opens on 500 Remaining Acres at Tustin Legacy
The City of Tustin launched a major public outreach effort this week inviting residents and stakeholders to weigh in on the future of the final 500 undeveloped acres at Tustin Legacy, the former Marine Corps Air Station that represents one of the largest infill development opportunities in California. The outreach, announced March 10, focuses specifically on the land surrounding Tustin's iconic blimp hangars, where the city is evaluating configurations of residential, commercial, and open space uses. The outcome of this community input process will shape master plan amendments that directly influence housing supply, commercial anchors, and long-term property values for the Tustin Legacy neighborhood and surrounding areas in the 92782 zip code. Residents can submit input through the Engage Tustin platform, with formal planning sessions expected to follow this spring.
What's Developing
[Costa Mesa] Fairview Developmental Center's Future Takes Shape at March Workshop
The City of Costa Mesa has scheduled three public workshops — March 24, 26, and 30 — to discuss the future land use of the Fairview Developmental Center, a large state-owned site that has been a focal point for regional housing advocates and developers. The site's conversion potential, which could yield thousands of new housing units depending on state and local approvals, makes it the most consequential long-term development signal in the city. Proximity to Mesa Verde neighborhoods means that whatever uses are ultimately designated will significantly affect property values and traffic patterns in that area for years to come.
[Santa Ana] $4.6M Street Rehabilitation Projects Move Forward on Fairview and Grand
Santa Ana's City Council has awarded contracts for two road improvement projects that will reshape key corridors in the city. The $3.4 million Fairview Street project will rehabilitate the stretch from Sunflower to Alton with new asphalt, updated medians, and video detection traffic signals, with the City of Costa Mesa contributing $96,000 for work within its boundaries. The $1.2 million Grand Avenue project covers Edinger to McFadden and prioritizes pedestrian safety and ADA-compliant sidewalks. Both projects are expected to complete by August 2026, improving commute corridors that connect Santa Ana to neighboring employment centers.
[Garden Grove] Brookhurst Place Phase IIA Adds 120 Apartments and 58,000 Sq Ft of Commercial Space
Construction is progressing on Brookhurst Place Phase IIA in Garden Grove's Koreatown district, the largest mixed-use development project in the city's history. The phase will deliver 120 new apartment homes alongside 58,000 square feet of commercial space, with an anticipated opening in 2026. The project anchors the ongoing revitalization of the Brookhurst corridor and follows the completion of the adjacent Garden Brook Senior Village. For buyers and renters tracking inventory in Garden Grove, Brookhurst Place represents a material addition to supply in a submarket that has historically had limited new multifamily product.
[Westminster] Mendez Tribute Monument Park and Freedom Trail Moves Toward Construction
Westminster is advancing the Mendez Tribute Monument Park and Freedom Trail, a civic infrastructure project that will create pedestrian connectivity between the city's Civic Center and the Little Saigon district. The project is designed to improve walkability, community identity, and foot traffic for businesses along the Bolsa Avenue corridor — a signal that Westminster is actively investing in the physical environment around its most economically active district, ahead of the broader Westminster Mall redevelopment timeline.
Neighborhood Pulse
[Garden Grove] City Moves to Ban Nitrous Oxide Use in Public Spaces
Garden Grove officials moved in early March to ban recreational use of nitrous oxide — commonly called whippets — in parks and commercial areas throughout the city. The ordinance targets a recurring nuisance issue in central Garden Grove and is part of a broader effort to improve livability in neighborhoods adjacent to the Koreatown and Little Saigon corridors. For homeowners and landlords in the area, the ban signals that city leadership is using code tools proactively to maintain neighborhood quality alongside ongoing economic development investments.
[Villa Park] Water Rate Decision Approaching for High-Value Homeowners
The Serrano Water District is holding its third and final Rate Study Workshop on March 19, the last opportunity for public input before the district finalizes water rate adjustments for the next fiscal year. Villa Park's large-lot residential properties carry above-average landscaping water demands, meaning rate increases represent a meaningful shift in carrying costs for homeowners. Property owners should attend or review the workshop findings as they factor into annual ownership cost projections.
[Santa Ana] Residents Get a Say on $2.7M in Unallocated Quality-of-Life Funds
Santa Ana has scheduled three community budget meetings — March 19, March 24, and April 9 — where residents can provide input on how $2.7 million in unallocated quality-of-life funding will be spent. The Washington Square and Riverview West neighborhoods have emerging high-demand priorities around park maintenance. For homeowners in those areas, the outcome of these meetings will influence neighborhood conditions and long-term livability scores that factor into home values.
[Garden Grove] Code Enforcement Ramps Up in Koreatown and Little Saigon
Garden Grove's 2026 Strategic Plan, finalized after the February city council retreat, identifies code enforcement as one of the city's top two priorities this year. Officials began intensifying commercial signage enforcement in the Koreatown and Little Saigon corridors on March 10, targeting unpermitted signage that the city says impacts neighborhood aesthetics and property presentation. Business owners along the Brookhurst and Garden Grove Boulevard corridors should review their signage compliance before formal notices are issued.
[Westminster] Planning Commission Fills Backlog After Quorum Delay
Westminster's Planning Commission, which was forced to adjourn its March 4 meeting due to a lack of quorum, successfully reconvened on March 10 and worked through backlogged Sign Update ordinance items including Ordinance No. 2633. The commission is also accepting applications for an unscheduled vacancy through March 18. The quorum issue caused a temporary delay to several pending land use hearings, though the commission confirmed all backlogged items are now on track.
Client Conversation Starters
When your client asks about renting out a property in Santa Ana... here's what to say:
Santa Ana just approved an ordinance banning algorithmic rent-setting software, which means landlords can no longer use platforms that coordinate pricing across properties to set or adjust rents. If your client owns or is considering a multifamily investment in Santa Ana, they should review any active software subscriptions used for rent management and confirm those tools aren't affected. This is a new compliance layer that's specific to Santa Ana right now, but it's worth watching whether neighboring cities follow with similar rules.
When your client asks whether Costa Mesa is a good place to own a rental... here's what to say:
Costa Mesa's City Council is holding a public hearing this Tuesday on amendments to its Tenant Protection Ordinance that would tighten eviction procedures and potentially require larger relocation payouts for displaced tenants. The city is also reviewing its Housing Element fees at the same meeting, which could affect development costs for new projects. For existing landlords, the practical takeaway is that relocation assistance costs may rise. For buyers evaluating Costa Mesa rentals, it's worth waiting until after Tuesday's vote to fully assess the operating environment.
When your client asks about buying in Tustin Legacy... here's what to say:
Tustin just opened a public input process for the final 500 undeveloped acres at Tustin Legacy, particularly around the historic blimp hangars. What gets built on that land — more housing, commercial space, or open space — will directly shape what it's like to live there long-term. The process is in early stages, so buyers who get in now are essentially buying ahead of that master plan decision. That's upside if the outcome is favorable, and it's worth staying engaged with the Engage Tustin platform to track how the plans evolve.
