A co-owner can technically rent a jointly owned property on an Airbnb or another short-term rental platform without the other co-owner’s permission. However, in a partition action, the court can force the renting co-owner to account for the income, pay for any exclusive use, and ultimately end the co-ownership.
California treats co-owners as having an equal right to possession, but pairs that right with a duty to account for income generated from the property. When one co-owner monetizes the property through short-term rentals and refuses to share the proceeds, the other co-owner has clear statutory remedies.
A Co-Owner Can Rent a Property on Airbnb, but Must Account for the Income in a California Partition Action
Under California co-ownership law, each tenant in common has an equal right to possess the property, regardless of ownership percentage. For example, this means you still have possession rights even if you have only 33% ownership rights in a California property
The catch is the accounting duty. California Code of Civil Procedure Section 872.140 states:
The court may, in all cases, order allowance, accounting, contribution, or other compensatory adjustment among the parties according to the principles of equity.

In practice, the renting co-owner must account for the gross rental income from each booking, less legitimate operating expenses such as cleaning fees, platform fees, and a proportionate share of property taxes and insurance.
The net amount is then split according to ownership percentage. The renting co-owner cannot keep all of it, even if they did the work to manage the rentals. This is captured in the broader doctrine of partition offsets and accounting, which a qualified partition attorney quantifies at the end of the case.
Listing a jointly owned property on Airbnb often goes beyond simply renting it out. When paying guests occupy the property to the exclusion of the non-renting co-owner, the law calls that ouster.
Ouster is the legal term for excluding a co-owner from possession. Once a co-owner is ousted, they are entitled to damages for ouster in addition to a share of any income generated during the exclusion.
The leading authority is Hunter v. Schultz, which establishes that a co-owner in sole possession of jointly owned property can be charged with the rental value of the property. When a co-owner is using the property to run an Airbnb operation, the rental value calculation captures the income they are generating from each guest stay.
To formalize the claim, the excluded co-owner can serve a notice of ouster under California Civil Code Section 843, which puts the renting co-owner on legal notice of the exclusion.
Practical evidence in an Airbnb dispute includes platform listing screenshots, calendar bookings, payout records, and guest reviews, much of which is accessible to the platform host and increasingly easy to obtain by subpoena once a partition action is filed.
A California Partition Action Forces a Resolution When a Co-Owner Won’t Stop Airbnb Rentals
When the renting co-owner refuses to share income or stop the Airbnb operation, a partition action is the cleanest path to resolution.
Under California Code of Civil Procedure Section 872.210, any co-owner with a qualifying interest can file. And under California Code of Civil Procedure Section 872.710(b), partition “shall be as of right unless barred by a valid waiver.” Filing the action does three things at once:
- Triggers a lis pendens that clouds title and limits the renting co-owner’s flexibility
- Sets up the accounting under California Code of Civil Procedure Section 872.140 so every dollar of Airbnb income is on the table
- Moves the case toward either a buyout or a partition by sale that ends the dispute permanently
This is the leverage you do not have through ordinary negotiation. The renting co-owner who has been running an Airbnb without will need to has to account for every dollar collected and claimed expenses. Critically, a subpoena to Airbnb often simplifies this process through the production of a spreadsheet explaining each rental, payment, and expense.
