Summary
Antioch Municipal Code § 11-3.10 requires landlords to give tenants written notice of their Rent Stabilization Ordinance rights at move-in and again with every rent increase notice. A rent hike is not legally effective until the landlord has met every notice requirement in the chapter.
§ 11-3.10 NOTICE REQUIREMENTS.
(A) On or before the date of commencement of a tenancy, the landlord of any residential real property subject to this Rent Stabilization chapter shall deliver to the tenant written notice of the following in a form prescribed by the city:
(1) The tenancy is regulated by this Rent Stabilization chapter, Antioch Municipal Code, Title 11, Chapter 3; and
(2) The tenant has a right to submit a complaint to the city pursuant to § 11-3.13 or a rent reduction petition pursuant to § 11-3.06 for rent charged in violation of this Rent Stabilization chapter; and
(B) At the same time and with any notice to increase rent, the landlord must deliver written notice of the following:

Violations & Fines
Serving a rent increase without the § 11-3.10 notice makes the increase legally ineffective under § 11-3.09(A)(1), meaning the tenant can keep paying the old rent and the landlord cannot enforce the higher amount through eviction. A tenant who is billed the increase anyway can file a petition to determine compliance with a city Hearing Officer under § 11-3.09(C), or a rent reduction petition under § 11-3.06.
