LA’s New 1-4% Rent Cap: What RSO Landlords Need to Know About the Biggest Change in 40 Years

If you own rent-stabilized property in Los Angeles, pay attention. The City Council just passed the most significant revision to the Rent Stabilization Ordinance since the law was created in 1979.

This isn’t a tweak. It’s a structural change to how rent increases work for roughly 650,000 units across the city—and depending on your portfolio, it could meaningfully affect your operating math.

Here’s what changed, what it means, and what you should be thinking about.

What Actually Changed

On November 12, 2025, the LA City Council voted 12-2 to revise the RSO’s rent increase formula. Under the new rules:

What Changed	Old Rules	New Rules
Annual Rent Increase Cap	3% to 8% based on CPI	1% minimum, 4% maximum (90% of CPI)
Utility Pass-Throughs	1-2% additional for landlord-paid gas/electric	Eliminated
Additional Tenant Surcharge	Allowed when tenant added dependents	Eliminated

The Council has directed the City Attorney to draft the formal ordinance language. Once ratified, the new rules are expected to take effect for rent increases in early 2026.

Who This Affects

The RSO applies to rental units in buildings constructed before October 1, 1978. That’s about 650,000 units in Los Angeles—mostly older apartment buildings, duplexes, and multi-family properties.

If you own RSO-covered property, this affects you directly. If your buildings were constructed after 1978, or if your units are exempt for other reasons (single-family homes, condos, certain subsidized housing), these changes don’t apply.

Not Sure If Your Property is RSO-Covered?

The LA Housing Department maintains a database of RSO properties. Check at housing.lacity.org/residents/rso-overview to confirm your status.

What This Means Practically

Let me be direct about what I’m seeing from landlords I work with:

The cap tightens your margin for error. With increases capped at 4% maximum—and likely lower in most years—your ability to recover from unexpected expenses through rent adjustments is more limited. Deferred maintenance, insurance spikes, and property tax increases eat into that margin faster.

Utility pass-throughs disappearing matters. If you’ve been relying on that 1-2% add-on for gas or electric, you’ll need to absorb those costs or find other efficiencies. For landlords who cover utilities, this is a real hit.

The dependent surcharge removal is less impactful for most. Most landlords I know weren’t charging this anyway—it was always awkward to enforce. But if you were using it, that revenue disappears.

The Bigger Picture

This change didn’t happen in a vacuum. LA has been under pressure for years to address housing affordability, and city leadership decided that tightening RSO protections was part of the answer.

Tenant advocates are calling this a major win. They argue it will stabilize rent burdens for hundreds of thousands of renters and make the city more accessible for long-term residents.

Landlord and developer groups have pushed back, warning that tighter restrictions could discourage investment in older buildings and make it harder for smaller landlords to cover rising costs—particularly insurance premiums, which have spiked across Southern California.

The Reality

Both perspectives have merit. This is the regulatory environment we’re operating in now. The question isn’t whether you agree with it—it’s how you adapt.

What Smart Landlords Should Do Now

Based on what I’m seeing in the field, here’s my advice:

• Get ahead of deferred maintenance. With tighter rent increase caps, you can’t count on future increases to cover today’s neglected repairs. Fix things now while you have the cash flow to absorb it.

• Know your compliance obligations. RSO properties in LA City already face significant regulatory requirements. Many also fall under RHHP if they’re in unincorporated County areas, or SB 721 if they have balconies. Stacking compliance failures creates compounding problems.

• Review your insurance strategy. Insurance costs have exploded, and you can no longer offset them with larger rent increases. Shop your coverage, adjust deductibles strategically.

• Document everything. In a tighter regulatory environment, your documentation is your protection. Inspection reports, maintenance records, tenant communications—all of it matters more.

• Consider your long-term strategy. For some landlords, tighter RSO restrictions may affect whether holding a property makes sense versus selling or converting. That’s a conversation worth having with your advisors.

The Bottom Line

LA’s rent control framework just got significantly tighter. Whether you think that’s good policy or not, it’s the reality for the foreseeable future.

The landlords who’ll navigate this best are the ones who maintain their properties proactively, stay ahead of compliance requirements, and operate with enough margin to absorb surprises.

The ones who’ll struggle are those running their buildings at the edge—deferred maintenance, minimal reserves, hoping rent increases will bail them out later.

If you’re not sure where your property stands from a compliance perspective—whether it’s RHHP readiness, SB 721 balcony requirements, or just general habitability—that’s what I do. A proactive inspection now costs a fraction of what reactive problems cost later.
