California Squatters Rights and Adverse Possession Laws (2026)

In California, a squatter must occupy a property for 5 continuous years, hold it adversely to the record owner's title, and pay all property taxes during that period to claim adverse possession under Cal. Civ. Proc. Code §§321 and 325. Removing an unauthorized occupant requires a court order, and which court action applies depends on whether the occupant ever had a tenancy, a licence, or any other permission to be there.

Adverse Possession in California: Period and Elements

Under Cal. Civ. Proc. Code §321, a person who establishes legal title is presumed to have been in possession, and anyone else's occupation is deemed to be under and in subordination to that title unless the property "has been held and possessed adversely to such legal title, for five years before the commencement of the action."

California courts describe that adverse holding through five elements, which must all be satisfied for the full 5 years:

1. Actual possession - The claimant must physically occupy the property.
2. Open and notorious - The occupation must be visible and obvious, sufficient to put the true owner on notice.
3. Exclusive - The claimant cannot share possession with the public or the true owner.
4. Continuous - Occupation must be uninterrupted for the full 5-year period.
5. Hostile - Possession must occur without the owner's permission or consent.

These elements are not all housed in a single section. Section 321 supplies the adverse-holding requirement and the 5-year clock, §325 supplies the permitted modes of possession and the tax requirement, and the open-and-notorious and exclusivity elements come from California case law rather than from the code itself.

Section 325(a) adds a possession requirement that is stricter than most states, and its own text limits where it applies. It governs "an adverse possession by a person claiming title, not founded upon a written instrument, judgment, or decree," and it deems such land possessed and occupied "in the following cases only": where it has been protected by a substantial enclosure, or where it has been usually cultivated or improved. On that track, vague or sporadic use is not enough.

Critically, §325(b) provides that "in no case shall adverse possession be considered established under the provision of any section of this code" unless the land has been occupied and claimed for five continuous years and the claimant has timely paid all state, county, or municipal taxes levied and assessed on the land for that period. Payment must be established by certified records of the county tax collector. This tax-payment requirement is one of the most significant barriers to a successful adverse possession claim in California.

Under Cal. Civ. Proc. Code §322, a claimant holding color of title (meaning they entered under a written instrument purporting to convey the property, or under the decree or judgment of a competent court) may establish adverse possession after 5 years of continued occupation. What counts as possession on that track is set by §323, not by §325(a), and §323 is broader. It deems land possessed and occupied where it has been usually cultivated or improved; where it has been protected by a substantial inclosure; where, although not inclosed, it has been used for the supply of fuel, or of fencing timber for the purposes of husbandry, or for pasturage, or for the ordinary use of the occupant; and where a known farm or single lot has been partly improved, in which case the part left uncleared or uninclosed is deemed occupied for the same length of time as the improved and cultivated part.

Because §325(b) applies its tax-payment requirement to adverse possession under any section of this code, a §322 color-of-title claimant must still pay all state, county, and municipal property taxes for the full 5-year period, provable through certified county tax collector records. Section 322 also provides that where the property consists of a tract divided into lots, possession of one lot is not deemed possession of any other lot of the same tract.

How to Remove a Squatter in California

California law requires property owners to use the court process to remove an unauthorized occupant. Self-help methods are prohibited.

What owners cannot do:

• Change the locks without a court order
• Shut off electricity, water, or gas to force a squatter to leave
• Remove or dispose of a squatter's personal property
• Physically remove or threaten a squatter

Any of these actions can expose the property owner to civil liability.

Which court action applies:

The correct filing turns on the occupant's relationship to the property. This is where general squatter guidance most often goes wrong, because unlawful detainer is not a catch-all.

• Unlawful detainer (Cal. Civ. Proc. Code §1161) is written for tenants. The section opens, "A tenant of real property, for a term less than life, or the executor or administrator of the tenant's estate ... is guilty of unlawful detainer," and each numbered branch turns on a tenant or subtenant. Subdivision 1 also reaches a person who "became the occupant of the premises as a servant, employee, agent, or licensee" once that relationship "has been lawfully terminated." A holdover tenant, a subtenant, a former resident manager, or a guest whose permission was revoked can be removed this way. A person who never had permission of any kind is none of those things.
• The 3-day notice to quit in §1161a(b) is not a general notice for unauthorized occupants. It applies only to a person holding over after specific transfers: a sale on a writ of execution, a foreclosure sale under a mortgage or a power of sale, a trustee's sale under Civil Code §2924, a sale by the occupant, or a sale under Health and Safety Code §18037.5, in each case where title under the sale has been duly perfected.
• Forcible detainer (§1160) covers a person who, in the night-time or during the occupant's absence, unlawfully enters real property and then refuses to surrender it after a demand held out for five days. Section 1160(b) limits the "occupant" who may use it to someone who, within the five days preceding the unlawful entry, was in "peaceable and undisturbed possession" of the land, so this route fits a very recent intrusion rather than a settled occupation.
• Ejectment or quiet title is the route against a true stranger to title. Ejectment is a common-law action to recover possession, and a quiet title action may be brought under Cal. Civ. Proc. Code §760.020(a) "to establish title against adverse claims to real or personal property or any interest therein." Quiet title is also how an asserted adverse possession claim gets decided.
• Criminal trespass may run alongside the civil case. Under Penal Code §602.5(a), entering or remaining in a noncommercial dwelling house, apartment, or other residential place without the consent of the owner, the owner's agent, or the person in lawful possession is a misdemeanor, and §602.5(b) makes it aggravated trespass where a resident or other authorized person is present. Whether officers act is a local decision, and where the occupant asserts a colorable right to be there, police routinely refer the matter to civil court.

The unlawful detainer steps, where §1161 or §1161a applies:

1. Serve the written notice the statute requires - a 3-day notice to pay rent or quit under §1161(2), the notice fixed by the tenancy for a holdover, or the 3-day notice to quit under §1161a(b) after a qualifying sale. There is no general 3-day notice to quit for a person who never had permission to be on the property.
2. File an unlawful detainer complaint - If the occupant does not vacate after the notice period, file the complaint and pay the filing fee at the Superior Court for the county where the property is located.
3. Serve the occupant - The occupant must be formally served with the summons and complaint.
4. Attend the court hearing - The judge will hear both sides. If the owner prevails, the court issues a judgment for possession.
5. Obtain a writ of possession - The court clerk issues a writ authorizing the sheriff to physically remove the occupant.
6. Sheriff enforces the writ - Only a law enforcement officer may carry out the removal.

The California Courts Self-Help Center explains this process at selfhelp.courts.ca.gov, but its eviction guide is written for landlords removing tenants under a rental agreement and does not cover occupants who never had one. An owner facing a true stranger-occupant should expect an ejectment or quiet title action instead, and should get a California-licensed attorney involved early.

No California statute gives property owners an expedited or fast-track sheriff removal aimed specifically at squatters. Removal runs through the ordinary civil actions described above. SB 448, the anti-squatting bill introduced in the 2025-2026 session, was placed on the Senate Appropriations suspense file on May 12, 2025, held in committee, and returned to the Secretary of the Senate under Joint Rule 56 on February 2, 2026 without becoming law.

Timelines vary by county and caseload, but owners should plan for the process to take 30 to 45 days or longer from filing to physical removal, and longer still for an ejectment or quiet title case, which is an ordinary civil action rather than a summary one. Consulting a California-licensed real estate or eviction attorney is strongly recommended to avoid procedural errors that can delay the case.
