Can I Rent Out My ADU in California? (2026 Guide)

California law allows homeowners to rent out an ADU with almost no restrictions at the state level — no owner-occupancy requirement for standard ADUs, no rent control on units built after 2020 under Costa-Hawkins, and no state prohibition on short-term rentals. But local rules override on short-term rentals, and most California cities have them. Los Angeles caps short-term ADU rentals at 120 days per year. Sacramento requires a 30-day minimum lease for ADUs in most zones. San Diego prohibits short-term rentals in ADUs entirely outside the Mission Beach overlay. The right to rent out your ADU exists. The terms depend on your city.

California law says:

• Long-term rental (30+ days): Yes. Always allowed. Cities cannot prohibit it.
• Short-term rental (under 30 days): No. Banned for ADUs built after January 1, 2025.
• Owner-occupancy: Not required for standard ADUs. May be required for JADUs.
• Rent to family: Yes, including at below-market or no rent.
• Sale of ADU separately: Not allowed in most cases (ADUs cannot be sold independently from the primary home).

That covers the state-level rules. Local jurisdictions add their own layers, which is where it gets complicated.

Before 2024, California’s removal of the ADU owner-occupancy requirement was temporary — it was set to expire and potentially revert to allowing cities to require homeowners to live on the property. AB 976, signed into law in 2024, made the removal permanent.

What this means in 2026:

• You do not need to live on the property to build a standard ADU
• You do not need to live on the property to rent out a standard ADU
• You can own a property with an ADU, rent out both the primary home and the ADU, and live somewhere else entirely
• This applies to all ADUs permitted after January 1, 2020

The JADU exception: Junior ADUs (JADUs) — units under 500 sq ft built within the existing home footprint — may still require owner-occupancy. Under current law, the property owner must occupy either the primary residence or the JADU. This means you can rent out a JADU, but you need to live in the main house. Or you can live in the JADU and rent out the main house. You just can’t rent out both and live elsewhere.

If you’re building an ADU specifically as an investment rental, build a standard ADU (not a JADU) to avoid the occupancy restriction entirely.

This is the rule that catches the most people off guard. Effective January 1, 2025, California law prohibits short-term rental (less than 30 days) of ADUs and JADUs. This applies to all ADUs permitted on or after that date.

What the law says:

• ADUs permitted after January 1, 2025 cannot be listed on Airbnb, Vrbo, or any short-term rental platform for stays under 30 days
• ADUs permitted before January 1, 2025 may be subject to local short-term rental regulations (which vary by city)
• The 30-day minimum is a state-level floor — cities can impose stricter rules but cannot allow what state law prohibits

Why this matters for your budget: If you built your ADU expecting Airbnb income of $150 to $250 per night, that business model is no longer available for new ADUs. Long-term rental income at $1,400 to $3,200 per month is the realistic revenue expectation. Build your financial projections around long-term tenant income, not nightly rates.

State law sets the floor. Cities add their own regulations on top.

Sacramento

Sacramento has some of the most ADU-friendly rental rules in California:

• No additional rental registration or licensing required for long-term ADU rental
• No rent control on single-family properties with ADUs (California’s AB 1482 rent cap applies to properties with 2+ units, but single-family homes with ADUs are generally exempt if the owner provides proper notice)
• No local short-term rental ban beyond the state restriction — but ADUs permitted after 2025 are still subject to the state 30-day minimum
• Standard landlord-tenant law applies (California Civil Code)

Los Angeles

LA has the most complex ADU rental landscape in California:

• Rent Stabilization Ordinance (RSO): ADUs on properties with 2+ existing units may fall under LA’s rent stabilization, which limits annual rent increases. ADUs on single-family lots are generally exempt, but check with LA Housing Department (LAHD) for your specific property.
• Home-Sharing Ordinance: LA restricts short-term rentals to the host’s primary residence, with a maximum of 120 days per year. ADUs on properties where the owner lives on-site may qualify under certain conditions, but ADUs permitted after 2025 are still subject to the state 30-day ban.
• Rental registration: LA requires rental properties to be registered with LAHD. Register your ADU as a rental unit — failure to register can result in fines.
• Just Cause Eviction: AB 1482 (California Tenant Protection Act) applies statewide. You need a legally valid reason to evict a tenant. Month-to-month leases don’t give you the ability to remove a tenant at will.

San Diego

San Diego’s rental rules are more straightforward than LA’s:

• No city-level rent control (AB 1482 statewide cap still applies)
• Short-term rental ordinance restricts Airbnb-style rentals to primary residences — ADUs are not eligible for short-term rental permits regardless of when they were built
• No separate ADU rental registration requirement
• Standard California landlord-tenant law applies

ADU rental rates depend on size, location, finishes, and whether the unit has separate utilities. Here’s what ADUs are renting for across California’s major markets in 2026:

ADU Size	Sacramento	Los Angeles	San Diego
Studio / JADU (300 sq ft)	$1,100 – $1,400	$1,400 – $1,800	$1,300 – $1,700
1-bed (500 sq ft)	$1,400 – $1,800	$1,800 – $2,400	$1,700 – $2,200
2-bed (800 sq ft)	$1,800 – $2,300	$2,400 – $3,200	$2,200 – $2,800

How to price your ADU:

• Search Zillow, Apartments.com, and Craigslist for comparable 1-bed or studio rentals in your neighborhood. Your ADU should price 10% to 20% below equivalent apartment rent — it’s a backyard unit, not a standalone apartment building.
• If utilities are included, price accordingly. Tenants will pay more for all-inclusive rent, but your costs go up too.
• New, modern ADUs with in-unit laundry, a private entrance, and dedicated parking command the top of the range.
• Don’t overprice and sit vacant. A unit priced $100 below market that rents in a week beats a unit priced $200 above market that sits empty for two months.

ADU rental income is taxable. Here’s what you need to know:

Federal taxes:

• Rental income from your ADU is reported on Schedule E of your federal tax return
• You can deduct expenses directly related to the ADU: property taxes (proportional share), insurance, maintenance, repairs, utilities (if you pay them), and depreciation
• The ADU structure can be depreciated over 27.5 years — this is a significant tax deduction that many new landlords miss
• If you actively manage the rental, you may be able to deduct up to $25,000 in rental losses against your ordinary income (income limits apply)

California state taxes:

• Rental income is taxed as ordinary income at California’s marginal rate (up to 13.3%)
• Same deductions apply at the state level
• No special ADU tax exemptions in California

Property tax reassessment:

• Building an ADU triggers a supplemental property tax assessment on the improvement value only — not the entire property
• Your base property tax on the existing home does not change (Prop 13 protection applies)
• A $250,000 ADU might add $2,500 to $3,000 per year in property taxes — offset many times over by rental income

CalHFA grant tax note: If you received the $40,000 CalHFA ADU grant, that amount is reported as taxable income in the year received. Expect to owe $5,000 to $12,000 in additional taxes depending on your bracket. Read our CalHFA grant guide for details.

Renting an ADU makes you a landlord. California has specific rules about how you screen tenants and structure leases.

Tenant screening:

• You can check credit, income, rental history, and references
• You cannot discriminate based on race, color, religion, sex, gender identity, sexual orientation, marital status, national origin, ancestry, familial status, source of income, disability, or veteran status (California Fair Employment and Housing Act)
• Source of income protections mean you cannot reject a tenant solely because they pay rent with a housing voucher (Section 8)
• Application fees are capped at the actual cost of screening (California Civil Code Section 1950.6)

Lease requirements:

• Minimum lease term: 30 days (state law for ADUs built after 2025)
• Security deposit: Maximum 1 month’s rent for unfurnished, 2 months for furnished (as of July 1, 2024, under AB 12)
• Rent increases: Limited to 5% + CPI or 10%, whichever is lower, per year under AB 1482 (applies to most rental properties in California)
• Just cause eviction: Required under AB 1482 after 12 months of tenancy

1. Listing on Airbnb without checking the rules. If your ADU was permitted after January 1, 2025, short-term rental is illegal under state law. Even for older ADUs, most California cities restrict or ban short-term rental of ADUs. The fines can be significant — LA charges $2,000 per violation per day.

2. Not registering as a rental. Some cities (including Los Angeles) require rental unit registration. Failure to register can result in fines and loss of legal protections as a landlord.

3. Skipping the lease. A month-to-month verbal agreement might seem easier, but it leaves you unprotected. Use a written lease that specifies rent amount, payment date, security deposit terms, maintenance responsibilities, and utility arrangements. California landlord-tenant law applies regardless of whether you have a written lease — but proving terms without one is much harder.

4. Setting rent without market research. Overpricing your ADU by $200 per month costs you far more in vacancy than the extra rent would generate. Research comparable rentals in your neighborhood before listing.

5. Not separating utilities. If your ADU shares a water heater, electrical panel, or gas meter with the primary home, you’ll be paying the tenant’s utility costs and have no way to recover them fairly. Install separate meters or sub-meters during construction — it’s much cheaper during the build than as a retrofit.

Can I rent out my ADU in California?

Yes. California law prohibits local governments from banning long-term rental (30+ days) of permitted ADUs. If your ADU has a Certificate of Occupancy, you can legally rent it to a tenant.

Can I Airbnb my ADU in California?

No, for ADUs permitted after January 1, 2025. State law bans short-term rentals (under 30 days) for newly permitted ADUs. ADUs permitted before 2025 may be eligible depending on local regulations, but most California cities restrict or ban ADU short-term rentals.

Do I have to live on the property to rent out my ADU?

No, for standard ADUs. AB 976 permanently eliminated the owner-occupancy requirement for standard ADUs in California. You can rent out both the primary home and the ADU without living on-site. JADUs (junior ADUs) may still require owner-occupancy — the owner must live in either the main house or the JADU.

How much rent can I charge for an ADU in California?

ADU rental rates in California range from $1,100 to $1,400 per month for a studio in Sacramento, $1,400 to $1,800 in Los Angeles, and $1,300 to $1,700 in San Diego. One-bedroom ADUs rent for $1,400 to $2,400 depending on market. Rent increases are limited to 5% + CPI or 10% per year under AB 1482.

Do I pay taxes on ADU rental income?

Yes. ADU rental income is reported as ordinary income on both federal (Schedule E) and California state tax returns. You can deduct expenses including maintenance, insurance, proportional property taxes, and depreciation of the ADU structure over 27.5 years. Consult a tax professional for your specific situation.

Does building an ADU increase my property taxes?

Yes, but only on the value of the improvement. California Proposition 13 protects your base property tax assessment on the existing home. The ADU triggers a supplemental assessment on the new construction only — typically $2,500 to $3,000 per year in additional property taxes for a $250,000 ADU.

Can I rent my ADU to a family member?

Yes. You can rent your ADU to anyone, including family members, at any price — including below market or no rent at all. If you charge below-market rent, you may not be able to deduct rental losses on your taxes. The IRS requires you to charge fair market rent to claim rental expense deductions.

What is the minimum lease term for an ADU in California?

30 days. California law requires ADUs permitted after January 1, 2025 to be rented on leases of 30 days or more. This effectively bans nightly and weekly rentals. Month-to-month leases (30+ days) are permitted. There is no maximum lease term.
