Santa Ana's Rent Cap Is Now 2.87% — Here's What That Means for Your ROI

The City of Santa Ana officially announced that the maximum allowable rent increase under the Rent Stabilization and Just Cause Eviction Ordinance (Ordinance No. NS-3027) is 2.87% — effective September 1, 2026 through August 31, 2027.

‍ ‍

If you own a rent-stabilized property in Santa Ana, that number governs exactly how much more income you can collect over the next twelve months, no matter what the market is doing around you.

‍ ‍

Here's what 2.87% actually means in dollars — and why the more important question isn't about the cap at all. It's about whether holding makes sense compared to what you'd net from a sale right now.

‍ ‍

How the 2.87% Cap Is Calculated

‍ ‍

Santa Ana's rent stabilization formula applies to buildings built on or before February 1, 1995 (per Costa-Hawkins). The cap is set annually at the lesser of 3% or 80% of the change in the Consumer Price Index for the prior 12-month period.

‍ ‍

For the current cycle: the CPI change from May 2025 through May 2026 was 3.59%. Eighty percent of that is 2.87% — which falls under the 3% ceiling, making 2.87% the allowable increase.

‍ ‍

For context, the caps over the last three years have been:

‍ ‍

  • 2024–2025: 3.00% (80% of CPI hit the 3% ceiling)

  • 2025–2026: 2.42%

  • 2026–2027: 2.87%

‍ ‍

Santa Ana's local ordinance is materially stricter than state law. Under California's AB 1482, most other Orange County landlords can raise rents up to 8% this year (5% plus the local CPI of 3%). Santa Ana property owners are working with a cap that's roughly a third of what their Anaheim or Garden Grove counterparts can charge.

‍ ‍

What 2.87% Actually Means for Your Cash Flow

‍ ‍

Let's put this in real numbers.

‍ ‍

If your unit is currently renting for $2,400/month, a 2.87% increase adds $68.88/month — or $826.56 for the year.

‍ ‍

If you're at $2,800/month, you get $80.36 more per month, or $964.32 for the year.

‍ ‍

That's before accounting for any increase in operating costs — property taxes, insurance, maintenance, and management fees — which aren't capped and have been climbing faster than 2.87% annually in most categories.

‍ ‍

The math on holding gets harder when you layer in the just cause eviction requirements that come alongside the ordinance. If a tenant stops paying, the path to resolution is longer and more expensive in Santa Ana than in unprotected markets. The income ceiling is strict; the cost floor is not.

‍ ‍

This is the core of what we've been tracking as Santa Ana's rent control cap quietly compresses landlord returns over the long run. The problem isn't any single year's cap — it's the compounding effect of below-market increases stacking up year after year while the property's underlying value keeps climbing.

‍ ‍

What the Market Is Doing While Your Rents Are Capped

‍ ‍

Here's where the comparison gets real.

‍ ‍

Santa Ana home prices are up 6.6% year-over-year as of mid-2026, with a median sale price of $879,000. Homes are selling at 100.92% of list price — meaning above asking — and 48.57% of properties closed above list (up from 25% the year before). Average days on market sits around 45 days.

‍ ‍

The appreciation your property has generated this year is almost certainly larger than the total additional income 2.87% will produce. For most landlords, that gap is significant.

‍ ‍

That's the tension: your income is capped at 2.87%, but your equity isn't capped at all. If you're holding a rent-stabilized property primarily for cash flow, you may be optimizing the wrong metric.

‍ ‍

The Santa Ana ADU market update for August 2026 shows that properties with ADUs are trading at a meaningful premium over standard comps — buyers are underwriting the income potential, and in a market where inventory is tight, those properties are moving quickly.

‍ ‍

The Real ROI Question: Hold vs. Sell

‍ ‍

The decision to hold or sell a rent-stabilized property isn't really about 2.87% in isolation. It's about your total return — income plus appreciation — versus what you'd clear from a sale and what you could redeploy that capital into.

‍ ‍

Here's a simplified comparison:

‍ ‍

If you hold:

‍ ‍

  • Income growth: capped at 2.87% annually

  • Appreciation: potentially 5–7% based on current market trajectory

  • Carrying costs: rising (taxes, insurance, maintenance)

  • Tenant risk: just cause protections add friction to turnover

  • Liquidity: zero until you sell

‍ ‍

If you sell now:

‍ ‍

  • You capture the full appreciation stack built over your hold period

  • Proceeds can be redeployed into a newer property not subject to RSO (Costa-Hawkins exempts buildings built after 1995)

  • Or structured into a 1031 exchange to defer capital gains

‍ ‍

The 45/180-day 1031 exchange clock is where a lot of Santa Ana landlords trip up when they decide to exit. If you're thinking about selling and rolling proceeds into another investment property, understanding that timeline — and pre-identifying replacement properties — is the difference between a clean exit and a taxable one.

‍ ‍

ADU Properties Have a Different Calculation

‍ ‍

If your property has a permitted ADU, the analysis shifts. ADU units in Santa Ana are subject to RSO if the primary structure was built before February 1, 1995 — which means the cap applies to the ADU rent as well, not just the main unit.

‍ ‍

But the property's value is still being set by what buyers are willing to pay — and buyers are increasingly sophisticated about income properties with ADUs. They're underwriting cap rates, not just purchase price. Understanding how an income property with an ADU is actually valued when you go to sell is critical — because the capped income stream is one input into that calculation, not the whole picture.

‍ ‍

In a market where comparable ADU properties are clearing quickly and trading above list, the buyer pool for a well-positioned income property is real. And selling a tenant-occupied multi-unit — even with RSO-protected tenants in place — is more straightforward than most owners assume. Investors buying income properties want tenants. They're underwriting the rent roll, not planning to move in.

‍ ‍

Who Should Be Reassessing Right Now

‍ ‍

If any of the following describes you, the 2.87% cap announcement is a useful forcing function to actually run the numbers:

‍ ‍

You've owned the property for 10+ years. Your basis is low, your equity is high, and the gap between your capped rents and current market rents is probably substantial. The longer you hold, the more that gap compounds — but so does the capital gains exposure, which is another reason to look at a 1031 now rather than later.

‍ ‍

Your operating costs have risen faster than your income. Taxes, insurance, and maintenance increases aren't capped. If your NOI has been compressing year over year, 2.87% doesn't change the trajectory — it just gives you a number for the spreadsheet.

‍ ‍

You're at or approaching a major capital expenditure. Roof, HVAC, plumbing — big-ticket repairs on an RSO property with capped income and just cause protections are hard to recover from financially. Selling before that capex hits is often a cleaner outcome than selling after you've absorbed it.

‍ ‍

Your property has appreciated significantly. The appreciation you've built is real money, but it's not liquid until you sell. In a market trading at 100%+ of list, that equity isn't going anywhere — but it also isn't compounding.

‍ ‍

The Bottom Line

‍ ‍

2.87% isn't the story. The story is that your property's income is capped at 2.87% while appreciation, buyer demand, and the premium for ADU-enabled properties are all moving in the other direction.

‍ ‍

If you own a rent-stabilized multi-unit or ADU property in Santa Ana and haven't done a serious hold-vs.-sell analysis in the last 12 months, now is the right time. The market is moving; the cap isn't.

‍ ‍

Reach out if you want to run the actual numbers on your property — what it's likely worth today, what the income picture looks like held vs. sold, and whether a 1031 exchange makes sense for your situation. That conversation doesn't cost anything, and the math usually tells you more than the cap announcement does.
