In Antioch, the question that decides a rental's numbers is not the rent. It is the date on the certificate of occupancy. Antioch's Rent Stabilization Ordinance caps rent increases on many older rentals at a figure far below what state law allows, and whether a building is covered turns largely on whether it was first occupied before February 1, 1995. Separately, the city's just-cause eviction rules reach well beyond the rent cap, including single-family homes.
Here is how the ordinance works, which properties it covers, and what I would check before writing an offer on any Antioch rental.
What does Antioch's Rent Stabilization Ordinance limit?
The ordinance sits in Title 11 of the Antioch Municipal Code, "Tenant Protections." For covered units, section 11-3.04 limits a rent increase to the lesser of 3 percent or 60 percent of the most recent 12-month change in the Consumer Price Index for the San Francisco-Oakland-Hayward area. Only one increase is allowed in any 12-month period, and the code treats a reduction in housing services as an increase in rent.
Because the CPI figure the city uses is published every other month, the allowable percentage changes several times a year. The City of Antioch posts the current figure in a table on its Rent Program page. Check that table on the date you plan to serve a notice, not the date you bought the property.
Which Antioch rentals are covered, and which are exempt?
Section 11-3.08 lists the exemptions. The two that matter most to buyers come from Costa-Hawkins, the state law that limits local rent control:
- Units first issued a certificate of occupancy after February 1, 1995
- Units that can be sold separately from any other unit, such as a single-family home or a condominium
The city's FAQ puts it plainly for houses: the ordinance does not apply to a single-family home unless it was first occupied on or before February 1, 1995 and shares a parcel with another unit. A pre-1995 duplex, triplex or apartment building, or a house with an ADU on the same lot, is where coverage usually applies. Other exemptions include owner-occupied units and rooms in a home where the owner lives and shares a kitchen or bath.
Does the ordinance matter if the property is exempt from the rent cap?
Yes, and this is the part investors most often miss. Antioch's just-cause eviction rules in Chapter 6 apply to residential rentals generally. The exemptions in section 11-6.03 are narrow and cover things like hospitals, certain transitional housing and short hotel stays. They do not exempt single-family homes or newer buildings.
That chapter sets rules for owner move-in, including a 60-day notice and a requirement that the owner or qualifying relative move in within 90 days and stay for at least two years. It also requires relocation payments for no-fault terminations, set in section 11-6.06. A separate anti-harassment chapter applies to landlords and tenants citywide.
How does Antioch's ordinance fit with California's AB 1482?
California's Tenant Protection Act, Civil Code 1947.12, caps increases at 5 percent plus inflation or 10 percent, whichever is lower, and exempts units built within the last 15 years on a rolling basis. Units already covered by a stricter local ordinance follow the local rule. So a pre-1995 Antioch fourplex follows Antioch's lower cap, while a single-family rental may fall under the state law instead, depending on ownership and whether the required exemption notice was given to the tenant.
What should you check before buying an Antioch rental?
- The certificate of occupancy date. Before or after February 1, 1995 changes everything.
- How the parcel is configured. A house that shares a lot with a second unit is treated differently from one that stands alone.
- The rent history. Ask for the date and amount of every increase. The 12-month clock runs from the last one.
- Any Fair Return Petition history. Increases above the cap, including to recover capital improvements, go through that process.
- The landlord business license. Antioch charges an annual business license tax on rentals, listed on the city's Landlords page as $250 per single-family unit or $150 per attached multifamily unit plus application fees (checked September 2026). It is owed whether the unit is profitable or vacant.
- Existing leases and notices. Current tenants, and the protections attached to them, transfer with the property.

Frequently asked questions about rent stabilization in Antioch
Does Antioch have rent control?
Yes. Antioch's Rent Stabilization Ordinance limits increases on covered units to the lesser of 3 percent or 60 percent of the most recent 12-month change in the San Francisco-Oakland-Hayward CPI, with one increase per 12 months.
Is a single-family home in Antioch covered by the rent cap?
Usually not. The city says the ordinance applies to a single-family home only if it was first occupied on or before February 1, 1995 and shares a parcel with another unit.
Where do I find the current allowable increase in Antioch?
The City of Antioch publishes it in a table on its Rent Program page. The figure changes as new CPI data is released, so check it on the date you serve notice.
Do Antioch's just-cause eviction rules apply to newer homes?
The just-cause chapter applies to residential rentals broadly. Its exemptions are narrow and do not exclude single-family homes or newer buildings, so confirm the rules for any specific tenancy.
Does a landlord in Antioch need a business license?
Yes. The city's Landlords page lists an annual business license tax on rental units, owed whether the property makes a profit, a loss or sits vacant.
The Bottom Line on Buying a Rental in Antioch
Antioch has two layers of tenant rules. The rent cap turns on the building's date and configuration. The just-cause and relocation rules reach much further. Read both before you model the numbers, and get the rent history in writing before you are in contract.
