Rent Control and Rent Stabilization: What Small Landlords Need to Know

Many small landlords think of rent control as a big-city problem, until a state passes a statewide cap. Whether you can raise rent at all, how much, and what paperwork you owe depends on where the unit sits, when the building was built, and who owns it. Getting that wrong can cost you refunds and penalties.

This guide explains what rent control and rent stabilization mean, where they apply, who is usually exempt, how to check coverage for a specific unit, and how to run your numbers when increases are limited. It is part of our compliance and legal hub for independent landlords and small property managers.

Note: This article is general education, not legal advice. Rent regulation varies by state and municipality and changes often, and the figures below are dated snapshots as of October 22, 2026. Confirm current rules with the agency that publishes them or with a local attorney before you set or change rent.

Rent control vs. rent stabilization: what the terms mean

People use the two terms loosely, and some statutes mix them. In general:

• Rent control traditionally means a hard limit on what a landlord may charge for a covered unit, often for older tenancies, sometimes with the rent tied to a government formula.
• Rent stabilization usually means a system that allows annual increases within a set range, often set by a board or a formula, while the unit stays in the program from tenant to tenant.
• Rent cap laws are the newer statewide versions. They let you raise rent each year up to a percentage ceiling.

The label matters less than the details: which units are covered, how much you may increase, what notice you owe, and whether you must register the unit.

Which states and cities limit rent increases

The map is uneven. The sections below cover the statewide caps and the best-known stabilization system. Many cities have their own ordinances, so check the city and county too.

California: the statewide cap under AB 1482

California's Tenant Protection Act, commonly called AB 1482, limits annual increases for covered units to 5 percent plus the regional change in the Consumer Price Index, or 10 percent, whichever is lower. The cap is codified in Civil Code section 1947.12, took effect January 1, 2020, and is scheduled to expire January 1, 2030, according to San Francisco's published guidance. The percentage changes with each period and by region. For example, San Francisco published a maximum of 8.8 percent for August 1, 2026 through July 31, 2027, which is 5 percent plus a 3.8 percent CPI figure. Your area may differ, so look up the figure for your region. A covered tenant also may not receive more than two increases in a 12-month period, and the combined total must stay within the cap.

Oregon: the statewide cap under ORS 90.323

Oregon limits increases for most tenancies after the first year. Under ORS 90.323, you may not raise rent during the first year of a tenancy, you must give at least 90 days of written notice after that, and you may raise rent only once in any 12-month period. The percentage cap is set each year by the state Department of Administrative Services as 7 percent plus CPI, with a ceiling of 10 percent. The department lists 9.5 percent for 2026 and 10 percent for 2027.

Washington: the statewide cap under HB 1217

Washington enacted its statewide cap in May 2025, under RCW 59.18.700. After the first year of a tenancy, increases in any 12-month period are limited to 7 percent plus CPI or 10 percent, whichever is less, and under RCW 59.18.140 landlords generally must give at least 90 days of written notice. The state Department of Commerce publishes the figure each year after the June consumer price data is released, and it lists 9.683 percent for calendar year 2026 and 10 percent for 2027.

New York City: rent stabilization

New York City runs the best-known stabilization program. Per New York State Homes and Community Renewal, rent stabilization generally covers buildings built after 1947 and before 1974, apartments removed from rent control, and buildings that receive J-51, 421-a or 421-g tax benefits, and each of those programs has its own rules about which apartments are covered. The Rent Guidelines Board sets the allowed increases for one-year and two-year renewal leases. In June 2026 the board voted to freeze rents on both lease lengths for leases starting October 1, 2026 through September 30, 2027, according to press reports. A landlord lawsuit challenging the freeze was still pending as of early October 2026, so confirm the status before you issue a renewal.

Everywhere else: preemption and local rules

Many states bar cities from adopting rent control at all. A 2019 National League of Cities analysis counted 36 states where cities lack authority to adopt rent control, so treat it as a starting point. In a preempting state, no local formula limits the amount, though your lease and state notice rules still apply. In places that allow local control, a city ordinance may be stricter than, or replace, the statewide cap. California's AB 1482 cap, for example, does not apply to units under a local ordinance that limits increases to less than 5 percent plus CPI, per San Francisco's guidance.

Typical exemptions for small landlords

Most laws exempt some properties, and small owners often qualify. Read the statute for your state. Common examples:

• New construction. California exempts units first built within the last 15 years on a rolling basis. Oregon exempts units whose first certificate of occupancy was issued less than 15 years before the increase notice. Washington exempts units for 12 years after the first certificate of occupancy under RCW 59.18.710.
• Owner-occupied small buildings. California exempts a two-unit property where the owner lived in one unit for the entire tenancy. Washington exempts certain owner-occupied small buildings, such as a duplex, triplex or fourplex where the owner lives in one unit at the start of the tenancy, if the owner is not a corporation or similar entity.
• Single-family homes and condos. In California, these are exempt only if the owner is not a real estate trust, a corporation, or an LLC with a corporate member, and the lease includes the required written exemption notice. Without the notice, the exemption does not apply, per San Francisco's guidance.
• Restricted affordable housing. Many caps also exempt certain regulated affordable housing, so read the exemption section of your state's statute.

In Oregon and Washington, a landlord who relies on an exemption must state the supporting facts in the increase notice. Document an exemption; do not assume it.

How to check whether a property is covered

Work through these steps before you set rent on a new purchase, a renewal, or a vacancy:

1. Check the state. Does it have a statewide cap or a stabilization law, or does it preempt local rent control?
2. Check the city and county. Search the municipal code for rent stabilization or rent ordinance, and call the housing department if unclear.
3. Find the certificate of occupancy date. New construction exemptions run from that date, so a building department record matters more than a listing.
4. Identify the owner type and the unit count. An LLC, a corporation, or a trust may change the answer for a single-family rental.
5. Look at the unit history. In New York, ask the state housing agency about the apartment's registration and rent history to confirm whether it is stabilized.
6. Write down the result. Save the finding with the date and source.

Our guide to rental registration and licensing requirements for landlords by city covers the separate question of whether your city requires you to register the property at all.

Allowed increases, registration, and reporting

Stabilization programs add paperwork. In New York City and in towns that adopted the Emergency Tenant Protection Act, owners of rent stabilized buildings must file annual registration statements for each covered unit with the state, per New York State Homes and Community Renewal, and late filings can bring fines. Some other cities with their own rent boards may also ask for registration or fees, so check the local program even when a statewide cap applies.

Notice requirements and just-cause rules

Rent limits rarely stand alone. They usually arrive with notice rules and with just-cause protections that restrict how you may end a tenancy.

• Notice length. Oregon and Washington both require 90 days of written notice for increases. Confirm your state and city period before you send anything.
• Required content. Oregon notices must state the amount of the increase, the new rent, the effective date, and any facts supporting an exemption. Washington's 2025 law prescribes a rent and fee increase notice form that must include the facts supporting any claimed exemption, so use the current state form rather than a generic letter.

Our template guide shows how to write a rent increase notice with a template, and you should adapt it to your state's wording. Just-cause rules matter because a rent limit means little if you can end the tenancy freely. California's AB 1482 applies just cause once tenants have lived in a covered unit for 12 months, and a lease expiring on its own does not count as a reason. For the full picture, read our overview of just cause eviction laws and what landlords need to know.

Running the numbers when increases are capped

A cap changes how you plan, because you cannot always catch up in one year. Here is an example with round numbers. Assume your area allows 5 percent plus a CPI figure of 3 percent, which is 8 percent, under a 10 percent ceiling.

• Current rent: $1,800 per month
• Allowed increase: 8 percent, which is $1,800 x 0.08 = $144
• Maximum new rent: $1,800 + $144 = $1,944 per month
• Extra annual income: $144 x 12 = $1,728

Then compare that figure with your cost growth in taxes, insurance, and maintenance, and plan for any gap:

• Ask whether unused room carries forward. Do not assume it does. If it does not, skipping an increase can permanently lower your income.
• Ask your attorney what happens at turnover. Whether you may reset rent for a new tenant depends on the statute and on whether a stabilization program applies.
• Budget for the cap in purchase analysis. Underwrite deals in capped areas with the maximum allowed increase, not the increase you hope for.
• Watch the calendar. Caps change every year, and the period is not always a calendar year.

Our guide to calculating and communicating a rent increase at renewal without losing tenants pairs well with this step.

Penalties for getting it wrong

The consequences differ by state, but they are real. Under ORS 90.323, an Oregon landlord who violates the cap owes the tenant three months of rent plus actual damages. In Washington, a landlord may owe a refund of the excess, damages of up to three months of the unlawful amount, attorney fees, and civil penalties of up to $7,500 per violation, and both the Attorney General and tenants can bring claims, under RCW 59.18.700.

Frequently asked questions

Does rent control apply to single-family rentals?

Sometimes. In California, a single-family home or condo is exempt only if the owner is not a trust, corporation, or LLC with a corporate member and the lease includes the exemption notice. Other states and cities differ.

What is the difference between rent control and rent stabilization?

Rent control usually means a strict limit on the rent for a covered unit, while rent stabilization allows annual increases within a set range, often set by a board. Statewide caps work like stabilization limits on yearly increases.

Can I raise rent between tenants in a rent cap state?

It depends on the statute and on whether a local stabilization program applies. The statewide caps are written as limits on increases, so confirm with your state agency or attorney how they treat a new tenant.

How much notice do I need to raise rent under a cap?

Oregon and Washington require 90 days of written notice after the first year of a tenancy. Other states and cities differ, so follow the stricter state or local rule.

How do I find the current rent cap percentage?

Use the state agency that publishes it, such as Oregon's Department of Administrative Services or Washington's Department of Commerce, and check the figure for the current year. In California, the cap depends on the regional CPI for your area.

What to do next

Rent limits only work for you when the facts are on file: the coverage decision, the current rent for every unit, the notice you sent, and the date each tenant received it. Small landlords usually get into trouble when those records sit in different inboxes and folders.

Shuk keeps the operating records in one place. Property Documents stores your coverage research, certificates, registrations, and signed notices inside each property, in any file type. Unlimited Adobe-powered e-signatures let you send an addendum or a rent notice you upload to one or several signers and see when each one signed. Centralized in-app messaging keeps your conversations with each renter in a thread tied to the property and tenant, with email and push notifications. The Rent Roll and Active Lease Overview reports are built in and export to Excel and PDF, so you can review current rents against your cap.

At as low as $2 per unit per month, with no setup fees and no contract, and with White Glove Onboarding included at no additional cost, Shuk makes a documented, consistent rent increase process feasible for landlords and property managers up to 200 units.
