AB 768 amends Civil Code §798.21 to change when a mobilehome space is exempt from local rent‑control ordinances and to add procedural protections for homeowners. The bill replaces the current “principal residence” trigger with a new 30‑day “used as permanent housing” occupancy test, requires park management to provide an explanation and the documents relied on before changing rent or other tenancy terms, and creates a homeowner rebuttable presumption against management’s reclassification.
The measure also narrows existing exemptions by limiting them to mobilehomes that are actively held available for sale. For park operators, landlords, local rent boards, and resident‑owners, the bill alters who can be subject to local rent limits and how disputes about residency status are decided — shifting compliance costs and evidentiary burdens toward park management while giving homeowners a clearer, though contestable, defensive tool.
At a Glance
What It Does
Replaces the ‘principal residence’ standard with a rule that treats a space as used as permanent housing only if the homeowner or an approved tenant occupies it for at least 30 consecutive days; before adjusting rent or tenancy terms based on a change in occupancy status, management must explain its determination and provide the documents it relied on. The homeowner may submit a statement refuting the claim, which the bill treats as creating a rebuttable presumption in the homeowner’s favor.
Who It Affects
Resident‑owners of mobilehomes, park operators and managers who perform residency reviews, local governments and rent boards that enforce rent limits, and parties buying or selling mobilehomes in parks. Investors or homeowners who rent spaces short‑term will see changes to whether local rent controls apply.
Why It Matters
The bill tightens procedural safeguards around reclassifying spaces for rent‑control purposes and narrows a prior exemption; that combination alters who falls inside local rent caps and how quickly management can change rents, potentially shifting litigation and enforcement over residency status from courts and agencies back into park‑level processes.

What This Bill Actually Does
Previously, Civil Code §798.21 treated a mobilehome as a homeowner’s principal residence unless state or county records showed otherwise, and allowed certain rentals by homeowners who did not occupy the space as their principal residence to be exempt from local rent‑control limits. AB 768 replaces that “principal residence” yardstick with a functional occupancy test: a space counts as being used as permanent housing only if the homeowner or an approved tenant occupies it for at least 30 consecutive days.
That changes the baseline question managers and local officials will ask when deciding whether local rent limits apply.
When a manager concludes after a records review that a space is not being used as permanent housing and therefore potentially subject to different rent or tenancy terms, the bill requires the manager to notify the homeowner and to provide both an explanation of the determination and copies of the documents relied on. The homeowner can respond with a statement refuting the manager’s claim; AB 768 makes that homeowner statement create a rebuttable presumption in the homeowner’s favor, which prevents management from immediately changing rents or tenancy terms unless it overcomes the presumption.AB 768 also narrows several of the prior categorical exemptions: rentals remain exempt from local rent‑control only when the mobilehome is actively held available for sale under the bill’s language.
That removes broader exclusions that previously applied when a space simply was not the homeowner’s principal residence. Altogether, the bill puts new procedural hurdles on managers who want to reclassify spaces while tightening the circumstances in which the exemption from local rent caps is available.For compliance teams and park operators the practical consequences are straightforward: update residency review procedures to account for the 30‑day occupancy threshold, prepare written explanations and documented records to justify any reclassification, and expect homeowner statements to block immediate rent or tenancy changes unless management collects additional evidence.
For local rent boards and enforcement officials the bill clarifies some standards but also creates new factual disputes about temporary occupancy, approved tenants, and what constitutes being “actively held available for sale.”
The Five Things You Need to Know
The bill substitutes a 30‑consecutive‑day “used as permanent housing” occupancy test for the prior ‘principal residence’ standard when determining exemptions from local rent limits.
Before modifying rent or other tenancy terms because a space is deemed not used as permanent housing, management must notify the homeowner and provide an explanation plus copies of the documents it relied on.
A homeowner’s written statement refuting management’s claim creates a rebuttable presumption in the homeowner’s favor and prevents management from implementing changes unless it later rebuts that presumption.
Exemptions from local rent‑control ordinances are limited under the bill to mobilehomes that are ‘actively held available for sale,’ narrowing the pool of exempt rentals.
The bill shifts the recordkeeping and initial evidentiary burden to park management by requiring them to produce the documents supporting a reclassification decision before altering terms.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Replace ‘principal residence’ with a 30‑day ‘permanent housing’ occupancy standard
This provision changes the legal trigger used to decide whether a homeowner’s rental of a mobilehome space is exempt from local rent caps. Instead of deeming a mobilehome the homeowner’s principal residence unless records show otherwise, the code will treat a space as used as permanent housing only if occupied by the homeowner or an approved tenant for at least 30 consecutive days. Practically, managers and local officials must evaluate actual occupancy patterns, not just recorded addresses.
Management must explain determinations and provide relied‑on documents
When management’s review leads it to conclude a space is not used as permanent housing, the bill requires written notice to the homeowner that includes an explanation of the determination and copies of the documents management used. This creates a contemporaneous record and prevents surprise changes; it also creates a tactical necessity for managers to assemble and retain documentary support before attempting to modify leases or rents.
Homeowner’s statement halts immediate changes unless rebutted
The homeowner can submit a statement refuting management’s claim that the space is not used as permanent housing. AB 768 treats that statement as creating a rebuttable presumption in favor of the homeowner, which bars management from altering rent or other terms while the presumption stands. The provision reduces the ability of managers to rely solely on records searches and forces them to obtain counter‑evidence to overturn a homeowner’s assertion.
Exemptions narrowed to units actively held available for sale
Where prior law exempted certain rentals from local rent regulations in broader circumstances, the bill restricts those exemptions to mobilehomes that are actively held available for sale. That narrows the class of spaces that automatically fall outside local rent limits and compels owners who are not actively marketing a unit to accept the applicability of local rent ordinances.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Homeowners who occupy their mobilehome as their primary residence: they gain a procedural shield because their written rebuttal creates a presumption that prevents immediate rent or tenancy changes.
- Resident‑owners who occasionally rent out space short‑term: the 30‑day test clarifies that very short stays may not trigger loss of permanent‑housing status, depending on facts, giving some predictability.
- Local enforcement bodies and compliance officers: a clearer occupancy standard and a required documentary disclosure give regulators better evidence to adjudicate disputes when management seeks to reclassify spaces.
Who Bears the Cost
- Park operators and management companies: they must assemble records, provide written explanations, and meet a higher initial evidentiary burden before changing rents, increasing administrative and legal costs.
- Homeowners who rent their space but do not actively list it for sale: they may lose prior broad exemptions and become subject to local rent controls, which could reduce rental income or complicate transfers.
- Tenants who occupy mobilehomes non‑permanently: where exemptions still apply, such tenants may face market rents rather than local‑cap rents, and enforcement of occupancy standards may produce uncertainty for short‑term occupants.
Key Issues
The Core Tension
The central dilemma is balancing homeowner autonomy against the risk of circumvention: AB 768 protects homeowners by treating their rebuttal as presumptive evidence, which guards against wrongful reclassification, but that same protection can be exploited to avoid local rent controls unless management is given clear, workable standards and a fair, prompt process to rebut homeowner statements.
The bill tightens process but leaves several operational gaps. It does not define key terms in the text provided here — notably “used as permanent housing,” “approved tenant,” and what qualifies as being “actively held available for sale.” Those gaps will force managers, homeowners, and local agencies to litigate or seek regulatory guidance over definitions and proof standards.
The requirement that management provide documents and an explanation before changing terms improves transparency, but it does not specify a time window for homeowner responses or a timeline for management to rebut the homeowner’s statement; those procedural details will determine whether the presumption is practically effective or merely symbolic.
Another implementation risk is creating incentives for strategic behavior. Homeowners might submit boilerplate statements to block legitimate reclassifications, while managers may seek more invasive record searches or heightened documentation (utility records, lease history) to overcome the presumption.
Narrowing exemptions to units actively held for sale clarifies some cases but raises questions about what constitutes active marketing (listed on MLS, participation of a broker, presence of a ‘for sale’ sign, open escrow) and how to verify that status without invading privacy or triggering litigation.
