California SB 1092: 360‑day notice and resident option to purchase mobilehome parks

Extends advance notice, creates a 180‑day resident matching window, allows assignment to public/qualified entities, and imposes stiff civil penalties for noncompliance.

The Brief

SB 1092 replaces California’s existing limited notice-to-residents scheme with a new, resident‑focused purchase opportunity framework for mobilehome parks. Under the bill, park management that intends to accept an offer to sell, lease, or otherwise transfer a park must give detailed notice at least 360 days before a final unconditional acceptance; resident organizations then have 180 days to submit a proposed purchase agreement supported by homeowners of more than 50 percent of the park’s homes.

If the resident organization’s proposal matches the price and substantially the same terms of the offer management plans to accept, the resident organization gains the right to purchase the park on those terms; management must otherwise negotiate in good faith and explain any rejections.

The measure also creates a Department of Housing and Community Development (HCD) certification process for “qualified entities” (local, regional, or national nonprofits and public agencies) and allows resident organizations to assign their rights to municipalities, housing authorities, state agencies, or certified qualified entities. The bill establishes civil penalties (the greater of $100,000 or 20 percent of the sales price) and authorizes actions by resident organizations and public prosecutors; it is drafted to be liberally interpreted to preserve affordable housing.

At a Glance

What It Does

Requires management to provide a written notice at least 360 days before making a final unconditional acceptance of an offer to sell, lease, or transfer a park, including price and contract terms. Gives a resident organization 180 days after that notice to deliver a written purchase proposal supported by more than 50% of homeowners, with a right to buy if its proposal matches the price and substantially the same terms of the conditional offer; enables assignment of rights to municipalities, housing authorities, state agencies, or HCD‑certified qualified entities.

Who It Affects

Park owners and managers, nonprofit resident organizations (including cooperatives), local governments and housing authorities, HCD (for certification and list maintenance), and prospective private purchasers who will face an extended notice period and potential matching rights. Attorneys and prosecutors also gain enforcement roles.

Why It Matters

It materially expands residents’ window to organize and assemble financing and inserts public and nonprofit actors into park acquisition pathways, increasing chances of preserving parks as affordable housing. The bill creates operational duties for management and a new HCD certification role, and it attaches substantial monetary penalties for noncompliance—changing the economics and risk calculus of park sales.

What This Bill Actually Does

SB 1092 overhauls how mobilehome park sales, leases, and transfers are handled when management receives an offer it intends to accept. Instead of the old, limited notice regime, management must now inform each household and several public entities at least 360 days before it makes a final, unconditional acceptance of any offer.

The notice must set out the intended transaction, homeowners’ statutory rights, the applicable deadlines, and the price, terms, and conditions of the offer or a copy of the purchase contract. If the transaction bundles multiple parks or unrelated properties, the notice must state both the aggregate price and the specific price allocated to the affected park.

After notice, a resident organization—defined broadly to include nonprofit corporations or cooperatives and able to designate an agent—has 180 days to submit a written proposed purchase agreement and a statement that homeowners of more than 50 percent of the park’s mobilehomes support the proposal (support may be shown by petition or signed document). Management must treat the resident organization’s proposal as a bona fide purchaser: it must make to the resident organization the same information provided to other prospective buyers and negotiate in good faith.

If management rejects the proposal, it must provide a written good‑faith reason within three days.If the resident organization’s proposed purchase agreement matches the price and substantially the same terms and conditions of the offer management has conditionally accepted or intends to accept, the resident organization gains the contractual right to purchase the park on those terms; management may not unreasonably delay or refuse execution or closing. The bill forbids rejecting a proposal solely because it includes a financing contingency, a particular financing type, payment method, or time to close.

If the parties sign a purchase agreement, the resident organization has 180 days to arrange financing (or a longer commercially reasonable period by agreement); failure to obtain financing within that period ends management’s duties under the article.The bill also allows a resident organization that represents at least 50 percent of homeowners to assign its statutory rights to the municipality, a local housing authority, a state agency, or a qualified entity certified by HCD, with the assignee able to exercise those acquisition rights; the resident organization may rescind any assignment at any time. HCD must create and annually update a list of certified qualified entities (local, regional, or national nonprofits and public agencies) based on demonstrated California experience and capacity; management must provide notice to qualified entities that request it.

The statute lists narrow exemptions (certain lot leases, financing‑related conveyances, eminent domain, and initial resident organization offers) but requires that exempt transactions not be a bad‑faith device to evade the law. Enforcement comes through civil actions by resident organizations and public prosecutors, with penalties set at the greater of $100,000 or 20 percent of the sales price and equitable relief such as injunctions available; ignorance of the statute is not a defense.

The Five Things You Need to Know

1

Management must send detailed notice to each resident household and to the local mayor/board chair, local housing authority, and HCD at least 360 days before a final unconditional acceptance of any offer to sell, lease, or transfer a mobilehome park.

2

A resident organization has 180 days after that notice to submit a written purchase agreement supported by homeowners of more than 50% of the park’s mobilehomes; support can be evidenced by signed petitions or similar documents.

3

If the resident organization’s proposal matches the price and substantially the same terms and conditions of the conditional offer management intends to accept, the resident organization gets the right to buy the park on those terms and management must not unreasonably delay or refuse closing.

4

Resident organizations may assign their rights to a municipality, local housing authority, state agency, or an HCD‑certified qualified entity (and may rescind that assignment at any time); HCD must certify qualified entities and maintain an annual list.

5

Management that violates the article faces a civil penalty equal to the greater of $100,000 or 20% of the total sales price; resident organizations and public prosecutors may seek penalties and injunctive relief.

Section-by-Section Breakdown

Every bill we cover gets an analysis of its key sections. Expand all ↓

Section 798.11.1

Definition: resident organization

Creates a broad statutory definition of “resident organization” to include nonprofit corporations formed under Revenue and Taxation Code Section 23701v, cooperative corporations, or other resident groups, and allows the organization to designate an agent. Practically, this lowers technical barriers for groups to qualify as resident organizations and signals the bill’s intent to let a range of resident‑led entities trigger the purchase process.

Section 798.11.2

Definition: qualified entity

Defines “qualified entity” as an organization certified by HCD under the new certification process. The label is the gateway for municipalities, housing authorities, and nonprofits to receive notices and to act as assignees of resident rights; certification therefore becomes a practical prerequisite for public or nonprofit acquisition strategies.

Section 798.83.1

360‑day notice: who gets it and what must be included

Specifies notice content and delivery methods: certified mail with return receipt, first‑class mail with tracking, and email if provided. Notices must go to each household and to the mayor/board chair, local housing authority, and HCD. For multi‑asset transactions the owner must state aggregate and park‑specific prices, which affects how residents evaluate the deal and whether resident acquisition is feasible.

4 more sections
Section 798.83.2

HCD certification and qualified‑entity list

Directs HCD to set up a certification process for local/regional/national nonprofits and public agencies that can operate the property for its useful life, maintain an annually updated list, and make it available to management. Management must send notice copies to qualified entities that request them. This creates an administrative role for HCD and a transparency mechanism for potential nonprofit or public purchasers.

Sections 798.83.3 and 798.83.4

180‑day submission window, >50% homeowner support, and good‑faith negotiation

Allows resident organizations to deliver a written proposed purchase agreement within 180 days of notice and requires a statement showing homeowner support by owners of more than 50% of the park’s mobilehomes. Management must negotiate in good faith, provide the same information it gives other buyers, and, if it rejects a proposal, supply a written good‑faith reason within three days. If the resident proposal matches the price and substantially equivalent terms of the conditional offer, the resident organization obtains the right to buy on those terms; management cannot reject solely for financing contingencies or the type/timeframe of financing.

Sections 798.83.5 and 798.83.6

Assignment, rescission, and narrow exemptions

Permits resident organizations representing at least 50% of homeowners to assign their rights to municipalities, housing authorities, state agencies, or certified qualified entities and to rescind assignments at any time; the assignee then inherits the acquisition rights. Lists exemptions—certain lot leases, financing‑incidental conveyances, eminent domain, and initial resident‑led offers—but conditions them on good‑faith commercial or familial purpose so they cannot be used simply to evade the statute.

Sections 798.83.7 and 798.83.8

Enforcement, penalties, and interpretive directive

Authorizes civil actions by resident organizations and by public prosecutors (AG, district attorneys, county/city attorneys) and allows courts to grant injunctions and other relief. Sets penalties at the greater of $100,000 or 20% of the sale price and states that lack of knowledge is not a defense. The article directs liberal construction to preserve affordable housing—an interpretive signal likely to influence courts’ approach to ambiguities.

Who Benefits and Who Bears the Cost

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.

Who Benefits

  • Mobilehome homeowners in affected parks — gain a long advance notice, a structured window (180 days) to organize and attempt to buy the park, and protection from quick closed‑door sales that could threaten long‑term affordability.
  • Resident organizations and cooperatives — obtain a statutory right to present a purchase agreement, access to seller information, a right to match equivalent offers, and the ability to assign rights to public or nonprofit actors to preserve park use.
  • Municipalities, housing authorities, and certified nonprofit housing operators — get a formal route to intervene or acquire parks (via assignment) to retain them as community assets or affordable housing without racing the private market.

Who Bears the Cost

  • Park owners and management — face extended pre‑closing notice obligations, the duty to negotiate in good faith, documentation burdens, potential delay to transactions, and exposure to substantial civil penalties for noncompliance.
  • Private prospective buyers and investors — may see deal uncertainty and longer timelines, and could lose transactions if resident proposals match the seller’s conditional offer; they also bear the business risk of potential litigation.
  • Department of Housing and Community Development — must build and run a certification process and maintain an annual list of qualified entities, creating administrative workload and staffing needs without an explicit funding source in the text.

Key Issues

The Core Tension

The central dilemma is balancing residents’ interest in preserving affordable, community‑controlled parks against owners’ and market participants’ interest in predictable, marketable real property transactions: the bill empowers residents and public actors to interrupt and match deals to preserve parks, but doing so imposes delay, uncertainty, and administrative burdens that can chill investment and complicate legitimate sales.

The bill tilts heavily toward resident acquisition and public/nonprofit intervention but leaves several operational and legal questions unresolved. “Substantially the same terms and conditions” is a key phrase that will generate disputes: does it permit minor funding or closing‑date variations, or will purchasers litigate over minute contract language? The statute prohibits rejecting proposals solely for including financing contingencies or for a particular financing vehicle, yet it gives the resident organization only 180 days after signing to secure financing—creating a tension between preventing contractual discrimination and ensuring a realistic closing timeline.

Buyers, sellers, and courts will need to work out how those two rules coexist in practice.

The 360‑day advance notice and the affirmative HCD certification role change transaction dynamics: sellers face a long exposure window in which resident organizations or public entities can marshal offers, and HCD must vet and list qualified entities without a funding mechanism in the bill text. The assignment/rescission construct is also double‑edged: it lets municipalities and housing authorities step in, but a rescindable assignment could produce uncertainty for private purchasers and complicate financing.

Finally, the penalty structure (the greater of $100,000 or 20% of the sale price) is large enough to deter violations, but it also creates high stakes for borderline technical breaches that could lead to contentious litigation over procedural compliance versus substantive fairness.
