LAHD is the Los Angeles Housing Department, the City of Los Angeles agency that administers the Rent Stabilization Ordinance (RSO) and the Just Cause Ordinance (JCO). It collects the annual registration fee on every rental unit in the city, receives the rent registry, takes eviction and buyout filings, and handles tenant complaints.
It is a city agency, so it has no authority outside City of Los Angeles limits. A building in Glendale, Santa Monica, or unincorporated LA County answers to a different office.
LAHD touches an owner at six points:
LAHD's annual bill page lists three per-unit charges. The delinquent amount applies if payment is not in by the last day of February:
Two details cost owners money. Fees are per unit and not prorated, so a unit rented for one month owes the full amount. And LAHD says a bill that never arrived does not excuse the fee or waive the penalty: the owner must pay and keep contact information current.
An owner can pass half of the RSO fee to the tenant as a $1.61 monthly surcharge with 30 days' written notice. LAHD no longer allows collecting it as a lump sum.
For July 1, 2026 through June 30, 2027, LAHD's Allowable Rent Increase Bulletin sets the annual RSO increase at 3%. The rule behind it: each year's percentage comes from the average CPI for the twelve months ending September 30, bounded between 1% and 4%. It is applied once every 12 months and is not cumulative or retroactive. Two 2026 changes matter: since February 2, 2026, no extra percentage for utilities, and no increase when an added occupant is a dependent.
A 3% increase also needs written notice: 30 days for increases under 10% within a year, 90 days for more.
A buyer's attorney will not ask whether you registered. The attorney will ask whether you can show the rent was collected legally. A missing certificate, an unfiled rent registry, or unpaid delinquent fees turn into a fix-it list in escrow, and a fix-it list becomes a price conversation.
Here is the uncomfortable part. The Rent Registry is the rent you told the city you charge. Your rent roll is the rent you say you collect. A buyer can lay the two side by side, and any gap between them is a question you have to answer with the contract open.
Fix it before you list: pay the arrears, file the registry, and pull the certificate. For a new owner, LAHD gives 45 days to register after acquiring the property and to file any temporary exemptions. See how rent control affects your sale price.

What does LAHD stand for?
Los Angeles Housing Department, the City of Los Angeles agency that runs rent stabilization, just cause eviction rules, and annual rental registration.
Is LAHD the same thing as RSO?
No. RSO is the law, and LAHD is the department that enforces it. LAHD also administers the Just Cause Ordinance, which covers most rental housing in the city that RSO does not.
Do I have to register with LAHD if my building is not rent-controlled?
Probably yes. LAHD states that annual registration is mandatory for all residential rental units in the City of Los Angeles. Non-RSO units pay the JCO fee instead of the RSO fee, and SCEP applies to units subject to it. Confirm your building's status with LAHD.
When is LAHD registration due, and what happens if I am late?
The annual fee is due in January, and a delinquent fee applies after the last day of February. The delinquent RSO fee is $58.13 per unit, against $38.75 on time. Collecting rent without a Registration Certificate is not allowed.
How much can I raise rent on an RSO unit?
LAHD's bulletin sets 3% for July 2026 through June 2027. Each year's number comes from CPI, with a 1% floor and a 4% ceiling, and applies once every 12 months.
I just bought an LA apartment building. How long do I have to register?
LAHD gives new owners 45 days to register the property and file any temporary exemptions.
How do I check or pay my LAHD registration?
Use LAHD's online customer portal to pay the annual bill and view statements. The Rent Registry is filed through the Rent Registry Portal at HousingBill.LAcity.gov. Registration is complete only after the fees are paid and the rents are submitted.
Does LAHD handle tenant buyouts?
It receives them. For an RSO unit, the owner must give the tenant a signed disclosure notice before the offer, and file the notice and signed agreement with LAHD within 60 days. The tenant has 30 days to cancel without penalty.
Does LAHD cover buildings outside the City of Los Angeles?
No. Unincorporated LA County has its own program under the DCBA, and other cities set their own rules.
Most owners do not learn what their LAHD file says until a buyer's attorney reads it aloud.
