If you own rental property in Los Angeles, registration is not paperwork you can put off. Until your units are registered and the fees are paid, you cannot legally raise the rent, and you cannot pursue an eviction that survives a tenant’s challenge. Los Angeles landlord registration is the precondition to almost every right you hold as a property owner, and the city and county enforce it through the one lever that hurts: your ability to collect.
Borna Houman Law represents landlords, property owners, and investors across Los Angeles County, from the Westside to the San Fernando Valley. Registration rules differ by jurisdiction, the deadlines are unforgiving, and a missed filing can stall an eviction you otherwise would have won.
Key Takeaway: Landlords in the City of Los Angeles must register rent-stabilized units every year with the Los Angeles Housing Department (LAHD) and pay the per-unit fee, and most other rentals must be registered under the city’s Just Cause Ordinance. In unincorporated Los Angeles County, owners register with the DCBA Rent Registry within 30 days of a new tenancy. An owner who fails to register cannot lawfully demand a rent increase or maintain an unlawful detainer.
Do you have to register your rental property in Los Angeles?
Yes, in almost every case. In the City of Los Angeles, units covered by the Rent Stabilization Ordinance, generally those in buildings with a certificate of occupancy issued before October 1, 1978, must be registered with LAHD each year under Los Angeles Municipal Code section 151.05. The city’s Just Cause Ordinance now reaches most other rentals as well, which means even newer buildings and many single-family rentals have a registration obligation.
In unincorporated Los Angeles County, registration runs through the Department of Consumer and Business Affairs under County Code sections 8.52.080 and 8.57.080. If you own a rental in an unincorporated area, you register within 30 days of the start of a tenancy and renew on the County’s annual cycle. Owner-occupied single-family homes that you do not rent out are not required to register.
What is the LAHD Rent Registry and who must use it?
The LAHD Rent Registry is the City of Los Angeles system where landlords record each rental unit, the current rent, and the tenancy details, then pay the annual registration fee. The city treats registration as complete only when every outstanding fee is paid and the required rent and tenancy information is submitted. A partial filing is not compliance.
The annual RSO registration fee runs about $38.75 per unit, and the ordinance allows the owner to pass half of it through to the tenant. The fee is small. The consequence of skipping it is not, because the city ties your right to collect a rent increase directly to a current registration. In our experience advising LA owners, the registration fee is the cheapest insurance a landlord buys all year, and it is the one most often forgotten on inherited or newly acquired buildings.
What happens if you do not register your LA rental?
An unregistered landlord cannot legally demand or accept a rent increase, and cannot maintain an unlawful detainer based on nonpayment of an increase that was never valid. Under LAMC section 151.05, a landlord who has not registered may not collect rent increases until the registration is current. Tenants and their counsel raise non-registration as a defense in eviction cases, and it can defeat an otherwise solid case.
The city and county also impose delinquency fees that grow the longer registration lapses. The real cost, though, is the stalled eviction. We have seen owners forced to dismiss an unlawful detainer, register, re-serve notices, and start over, losing months of possession because a registration lapse surfaced mid-case. Registering on time is far cheaper than curing a lapse in the middle of litigation.
How does LA County registration differ from the City?
The City of Los Angeles and unincorporated Los Angeles County run separate systems with separate deadlines, and a building’s location decides which applies. This table summarizes the major Los Angeles area registration regimes for owners.
| Jurisdiction | Who must register | Deadline | If you miss it |
|---|---|---|---|
| City of Los Angeles (LAHD) | RSO units and most Just Cause Ordinance rentals | Annual cycle; covered units on the city schedule | No rent increase collection; unlawful detainer defense; delinquency fees |
| Unincorporated LA County (DCBA) | RSO units and mobilehome spaces | Within 30 days of a new tenancy; annual renewal by Sept 30 | Late fees and enforcement actions |
| Culver City | Covered rental units | Re-register annually by July 31 | Penalties and rent increase limits |
| Santa Monica, Beverly Hills, West Hollywood | Rent-controlled units | Annual, set by each city’s rent board | Cannot raise rent; per-unit fees |
If you own across multiple cities, you are managing multiple calendars. A building in Culver City, a fourplex in the City of LA, and a unit in an unincorporated pocket near Altadena each answer to a different registry and a different due date.
What are the deadlines and fees for landlord registration?
The City of Los Angeles runs an annual registration cycle, and the County asks unincorporated-area owners to register within 30 days of a new tenancy and renew by September 30 to avoid late fees. Culver City requires annual re-registration by July 31. Santa Monica, Beverly Hills, and West Hollywood each set their own annual deadlines through their rent boards.
Fees are charged per unit, and several jurisdictions let the owner pass a portion to the tenant. Because the dollar amounts are modest, owners tend to treat registration as low priority, which is the exact mistake that later blocks a rent increase or an eviction. Calendar every deadline that applies to each property and confirm payment posted, not just that a form was submitted.
How does registration connect to rent increases and evictions?
Registration is the gate. A valid rent increase in a rent-stabilized unit requires current registration, so an unregistered owner who serves an increase has served an unenforceable one. The same logic reaches terminations: when you serve a compliant 60-day notice or move to evict for breach of lease, a registration lapse hands the tenant a defense.
Registration also interacts with the money you may owe a tenant at the end of a tenancy. Many LA jurisdictions tie relocation assistance for Los Angeles landlords to the same ordinances that require registration, so an owner out of compliance on one rule is often out of compliance on several. Getting registration right is the foundation for everything else, which is why it sits at the center of our work on rent control and regulatory compliance for owners.
Frequently asked questions about Los Angeles landlord registration
Do I have to register my rental property in Los Angeles?
Yes, in nearly all cases. City of LA RSO units and most Just Cause Ordinance rentals must register with LAHD, and unincorporated County rentals register with the DCBA. Only an owner-occupied home you do not rent out is generally exempt.
What happens if I do not register my LA rental?
You cannot legally collect a rent increase, and you cannot maintain an unlawful detainer that depends on an unregistered, invalid increase. You also accrue delinquency fees until registration is current.
How much is the Los Angeles rental registration fee?
The City of LA RSO registration fee is roughly $38.75 per unit per year, and the owner may pass half to the tenant. Other jurisdictions set their own per-unit amounts.
When is the registration deadline?
The City of LA runs an annual cycle, unincorporated County owners must register within 30 days of a new tenancy and renew by September 30, and Culver City requires re-registration by July 31. Confirm the exact date for each property you own.
Can I evict a tenant if my property is not registered?
It is risky. A registration lapse gives the tenant a defense and can force you to dismiss, register, re-serve notices, and restart the case. Register before you serve any notice.
