LA County rent registry due September 30
The Los Angeles County rent registry is due September 30 every year. Registering a fully covered unit costs $90.00 per unit per year, a registration filed after that date carries a 10% late penalty, and until the unit is registered the annual increase is not yours to take.

What filing requires
-
September 30
LA County rent registry annual filing due
File the annual rent registry for every covered unit and pay the registry fee.
A 10% late penalty applies after the deadline, and County Code §8.52.050.B lets you impose an annual increase only once the unit is registered, the fees are paid and you are in compliance. Unregistered, the increase is not yours to take.

Small property landlord self-certification: file before you use the extra 1%
The +1% (2.919% instead of 1.919%) only applies if you have self-certified as a small property landlord with DCBA, under penalty of perjury, and said so in the rent-increase notice. It is an annual certification, and DCBA's form tells you to file it with your annual registration.
On a $2,500 rent that extra 1% is about $300 a year per unit that you are otherwise not allowed to collect.
About this date: DCBA publishes no separate due date for the self-certification. Its form says to provide a copy when you submit the annual registration for the property, so we place the reminder on the September 30 registration deadline. If you plan to use the higher cap before then, file it first.

What being late costs

DCBA's rent registry page says a 10 percent late fee may be assessed on a registration submitted after the September 30 deadline.

We are not fully confident in this number. DCBA publishes the 10% but does not publish what it is charged on, or whether it repeats. Treat it as the floor of the cost of being late, not the whole of it.
§8.52.050.B: a landlord may impose an annual rent increase only upon registering the unit in the County's Rent Registry System, paying the annual registration fees required by §8.52.080, and being in compliance with federal, State and local laws and requirements. An increase taken without all three is unlawful, and §8.52.050.K lets the tenant raise that as a defence. DCBA's rent increase bulletin adds two more conditions to the same list: the tenant must have been given the Notice of Tenant Rights (§8.52.120), and the increase notice must carry the small property landlord or luxury unit statement where either higher cap is being used.

What we do not hold
- DCBA does not publish a standalone due date for the small-property-landlord self-certification. Its form directs you to file it with the annual registration, so our reminder sits on the September 30 registration deadline and the calendar entry says so.
- DCBA publishes a 10% late fee for registering after September 30 but does not publish the base it is charged on. We carry the 10% with that stated on the figure.
