How Much Rent Can an ADU Earn in California? (2026)

A California ADU typically rents for about $900–$1,600 a month in Central Valley cities like Fresno and $2,500–$6,500 in San Francisco, based on ADUByCity city data, as of 2026. In our Fresno example below, a self-managed unit keeps about 71% of gross rent after vacancy, maintenance, insurance, and property tax, before loan payments.

Key takeaways

• ›Rent depends mostly on city, size, and finish level. Check your city page for its range.
• ›Budget for vacancy, maintenance, insurance, and a property tax increase before you count profit.
• ›Cities cannot require you to live on site to rent an ADU (AB 976). A JADU can carry an owner-occupancy rule only if it shares a bathroom with the main home (AB 1154).
• ›JADUs cannot be short-term rentals, and many cities also ban short-term rental of ADUs.

How much do ADUs rent for in California cities?

Monthly rent ranges from our city data, as of 2026. The low end is usually a small studio or conversion, the high end a larger new unit in a strong neighborhood:

To narrow it down, look at current listings for comparable units near you. Recent actual rents beat any guide. Compare more cities on the ADU cost index.

How do you calculate ADU rental income?

1. ›Gross rent: monthly rent x 12.
2. ›Vacancy: subtract 5–8% for turnover.
3. ›Operating costs: maintenance (budget 1–2% of build cost a year), insurance, a property tax increase (roughly 1% of the added assessed value a year), and property management if you hire it (commonly 8–12% of rent).
4. ›Net operating income (NOI): gross minus vacancy minus operating costs.
5. ›Cash flow: NOI minus loan payments.

The ROI calculator runs these numbers for you, and the rent vs. sell tool compares renting with cashing out.

Worked example: a one-bedroom ADU in Fresno

Fresno has some of the lowest build costs in our data. Based on ADUByCity city data, as of 2026, a new ADU costs $150–$220 per sq ft there and rents for $900–$1,600 a month.

Assume a 600 sq ft one-bedroom built for $110,000 (inside the $90,000–$132,000 range that the per-sq-ft figures imply), renting at $1,300 a month, self-managed:

That is about a 10% return on the $110,000 build cost before financing. Staying under 750 sq ft also avoids impact fees, which Fresno waives below that size in line with state law. If you borrowed the full amount, subtract your annual interest to get real cash flow (see ADU financing).

The same math in a high-cost city looks different. A $350,000 ADU earning the same $11,000 would return about 3%, so higher rents do not always mean higher yields.

What changes the numbers most?

• ›Self-managing: saves the 8–12% management fee. Practical if you live on the property.
• ›Size: a second bedroom usually adds more rent than it adds cost, so price both layouts with the size calculator.
• ›Furnishing: can raise rent near hospitals, campuses, and job centers, but brings more turnover.
• ›Build cost: the biggest lever on yield. A garage conversion is often cheaper than new construction (see how much an ADU costs).

Do you have to live on the property to rent an ADU?

No. Under AB 976, cities cannot require the owner to live on site for an ADU, so you can rent both the main home and the ADU.

JADUs are different. Under AB 1154, a city can require owner-occupancy for a JADU only if the JADU shares a bathroom with the main home. A JADU with its own bathroom cannot be subject to that rule.

Can you rent an ADU on Airbnb?

Not a JADU. State law (AB 1154) bars short-term rental of JADUs.

For regular ADUs, it depends on the city, and many say no. From our city data:

• ›Compton requires a recorded covenant that bars rentals under 30 days.
• ›Garden Grove prohibits short-term rental of the main home, ADU, or JADU.
• ›Redding does not allow short-term rentals in ADUs.
• ›Palm Springs requires a separate short-term rental permit, subject to caps.
• ›Napa restricts short-term rental of ADUs in many residential zones.

Check your city page before you plan around nightly income.

Is an ADU subject to rent control?

State rent caps under AB 1482 (Civil Code §1947.12) do not apply to housing issued a certificate of occupancy within the previous 15 years, so a newly built ADU is generally outside them for that period. Local rent control and just-cause eviction rules vary, especially in cities like Los Angeles, San Francisco, and Oakland. Check your city's rules before you sign a lease. Tenant protections still apply once someone lives in the unit.

If you own a multifamily building, see ADUs on multifamily property.
