A manager drives the community and sees three things: an overgrown homesite, a shed nobody approved, and a set of steps coming away from a home.

Those look like one problem. They are three, governed by three different bodies of law, and treating them as one is how operators end up with a rule they can no longer enforce against anybody.

The overgrown site is probably a resident duty under a statute. The shed is an add-on that federal law explicitly does not regulate, which throws it to local building code and your own rules. The steps might be the resident's, or yours, depending on the state and on whether you own the home.

And underneath all three sits the question that decides whether any of it is enforceable: are your rules actually part of the tenancy, and have you applied them the same way to everyone? In New York, a rule not applied uniformly carries a rebuttable presumption that it is "unreasonable, arbitrary and capricious." Washington and Arizona make fair application a condition of enforceability outright.

This guide covers rules, inspections, violations and enforcement. It does not cover who has to fix what — that split is set out separately in the maintenance responsibilities guide — and it does not cover eviction for nonpayment, which is a different process entirely.

General information for operators, not legal advice. Rule enforcement is state-specific, and one of the federal standards below changed three months ago.

Key takeaways

• A rule is only enforceable if it meets statutory conditions — Washington and Arizona each impose six, including that the rule "apply to all tenants in a fair manner."
• Inconsistent enforcement is not a soft risk. New York creates a rebuttable presumption of unreasonableness where a rule is not applied uniformly.
• Cure periods range from 7 days to 90 — California 7, Florida 7, New York 10, Washington 20, Oregon 30, Colorado 90.
• Changing the rules is slow. California requires a meeting, 10 days' notice of it, and six months' notice of the amendment. Oregon lets residents of 51% of eligible spaces veto a change.
• HUD permanently rescinded its 2020 assistance-animal guidance on 22 May 2026 and replaced it with a narrower, training-based standard. Any policy written against the old guidance is out of date.
• Sheds, decks and carports sit in a federal gap. HUD's rules expressly do not govern add-ons — but the add-on must not compromise the home's HUD Code compliance.

Why MH inspections are different

In an apartment building, an inspection is an inspection of your own property. Everything you find is yours to fix, and the only question is when.

In a land-lease community, an inspection produces findings on three different sides of a line. Some belong to you — roads, common areas, the infrastructure you own. Some belong to the resident under statute. Some belong to the resident under your community rules, which is a weaker and more procedurally demanding basis than statute.

That last category is where the work is, because a community rule only binds if it survives four tests: it was properly incorporated into the tenancy, it is substantively reasonable, it was properly noticed, and it has been applied consistently. An apartment operator rarely has to prove any of that. An MH operator has to prove all four before a court will look at the violation itself.

Where your community rules get their force

Rules are not enforceable because they are in a binder. They are enforceable because a statute makes them part of the tenancy and they meet the statute's conditions.

Florida does the incorporation explicitly: §723.031(10) provides that "the rules and regulations and the prospectus shall be deemed to be incorporated into the rental agreement."

Washington imposes conditions. RCW 59.20.045 makes a rule enforceable only if, among other things, "their purpose is to promote the convenience, health, safety, or welfare of the residents, protect and preserve the premises from abusive use, or make a fair distribution of services and facilities," they "apply to all tenants in a fair manner," and they "are not retaliatory or discriminatory in nature."

Arizona imposes a near-identical six-part test under A.R.S. §33-1452, adding a specificity requirement — the rule must be "sufficiently explicit in prohibition, direction or limitation of the tenant's conduct" — and a pre-tenancy disclosure requirement: the prospective resident must have "a copy of the current rules and regulations before the prospective tenant enters into the rental agreement." Since 31 May 2016, new rules imposing recurring financial obligations are unenforceable against existing residents.

New York requires that rules "shall not be unreasonable, arbitrary or capricious," delivered when the written lease is first offered.

Colorado goes furthest. Under §38-12-214, rules imposing costs on homeowners or restricting their control of the home are presumed unreasonable unless management can show strict necessity for health or safety, legal compliance, voluntary agreement, or homeowner-organisation approval. In Colorado the burden runs against the operator by default.

Practical test: take any rule in your book and ask which of the statutory purposes it serves, whether it is explicit enough that a resident could tell what conduct is prohibited, and whether every resident received it before signing. A rule that fails any of those is decoration.

A condition is not automatically a violation

Not everything an inspection finds is enforceable against a resident.

A broken community-owned streetlight is a maintenance item. A tree limb over a homesite may be your responsibility or the resident's, depending on the state and on who planted it. Peeling paint on a resident-owned home is only a violation if a properly adopted rule says so.

The discipline is to route each finding to the right workflow at the moment it is recorded: operator maintenance, resident duty under statute, or resident duty under community rule. Those carry different obligations, different notices and different remedies. Mixing them produces notices of violation for things that were never the resident's problem — which is the fastest route to a selective-enforcement defence.

Who owes what, state by state, is set out in the maintenance responsibilities guide. Whether the community owns the home changes the answer materially, and that distinction runs through the park-owned versus tenant-owned analysis.

Changing the rules mid-tenancy

Operators routinely underestimate this. It is not a matter of issuing a new binder.

California — Civil Code §798.25 requires that "when the management proposes an amendment to the park's rules and regulations, the management shall meet and consult with the homeowners in the park," with "written notice given to all the homeowners in the park 10 days or more before the meeting." The amendment then takes effect with the individual homeowner's consent, or without it "upon written notice of not less than six months." Sixty days applies to recreational-facility rules and legally mandated amendments.

Florida — §723.037 requires at least 90 days' notice of a change in rules and regulations, to each affected homeowner and the HOA board, and a meeting with a homeowner-designated committee "no later than 60 days before the effective date."

Oregon — ORS 90.610 makes the change effective not less than 60 days after notice, and gives residents 30 days to object. The change takes effect "unless tenants of at least 51 percent of the eligible spaces in the facility object in writing." Residents have a genuine veto.

Washington — 30 days' written notice, plus "at least three months to comply with the new or amended rule after the thirty-day notice period," during which violations draw warnings only.

Colorado — 60 days' written notice, in English and Spanish, posted in a common area and conspicuously on each lot, with a 60-day window for a homeowner to file a complaint challenging the amendment.

Between the meeting requirements, the notice periods and the compliance grace periods, a rule change in California realistically takes seven months from decision to enforceability. Plan accordingly.

The notice of violation and the cure period

California's wording is worth having exactly: management may not proceed "unless and until the management has given the homeowner written notice of the alleged rule or regulation violation and the homeowner or resident has failed to adhere to the rule or regulation within seven days."

Note the citation. The rule-violation ground is now §798.56(a)(4), not the widely quoted §798.56(d) — the section was restructured in 2025 and (d) is now a definition of "financial institution." A notice citing the old subsection is citing the wrong provision.

Florida is prescriptive about delivery: written, "posted on the premises and sent to the mobile home owner and tenant or occupant by certified or registered mail, return receipt requested," and deemed given five days after postmark. Posting alone is not service.

Repeat violations

This is where a tracked history converts into a legal position — and where an untracked one throws it away.

Florida. A second violation of the same rule within 12 months is a ground for eviction, but only if you gave written notice "within 30 days after the first violation," specifying the conduct and allowing seven days to correct. And there is a hard cut-off: violations "occurring more than 1 year after the first violation of the same rule or regulation" do not constitute a ground.

Read that carefully. Miss the 30-day window on the first notice and the second violation gives you nothing. Wait 13 months and the clock has reset.

California. Where a homeowner "has been given a written notice of an alleged violation of the same rule or regulation on three or more occasions within a 12-month period," no written notice is required for a subsequent violation.

Oregon. If the resident cures but "substantially the same act or omission recurs within six months after the termination date," the landlord may terminate on at least 20 days' notice and the resident "has no right to correct the violation and avoid termination."

Washington. "Substantial violation, or repeated or periodic violations, of an enforceable rule" is a ground, but the notice must state that failure to cease, or any subsequent violation of that or any other rule, will result in termination.

Every one of these turns on the same two facts: which rule, and when. An operator who cannot produce a dated notice history per homesite per rule cannot use any of them.

Uniform enforcement, or no enforcement

The strongest express authority is New York's RPL §233: where "a rule or regulation is not applied uniformly to all manufactured home tenants of the manufactured home park there shall be a rebuttable presumption that such rule or regulation is unreasonable, arbitrary and capricious."

Washington's "apply to all tenants in a fair manner" and Arizona's identical language operate the same way — non-uniform application makes the rule unenforceable, not merely contestable.

We looked for MH-specific appellate authority holding that a park owner lost a rule through selective enforcement, and did not find one. The substantial body of selective-enforcement, waiver and estoppel case law sits in condominium and HOA law rather than under Chapter 723 or the MRL. That is an honest gap — but the statutory conditions above do not need case law to bite, because they are conditions of enforceability on their face.

One useful protection: Florida's §723.061(5) provides that accepting part of the lot rental amount with knowledge of noncompliance, after notice and termination, does not waive the termination — though you must account for the rent at final hearing.

What this means in practice: the enforcement record is the rule. If three homesites have unapproved sheds and you have noticed one, you have not enforced a rule — you have created a defence for the other two and arguably for the one you noticed.

Fair housing changed in May 2026

This is the most important update in this article, and it is recent enough that most published guidance has not caught up.

Assistance animals- On 22 May 2026, HUD's Assistant Secretary for Fair Housing and Equal Opportunity issued enforcement guidance stating: "I am permanently rescinding FHEO's 2020 notice regarding assistance animals." The replacement standard is materially narrower — FHEO "will find reasonable cause for failure to provide a reasonable accommodation involving the waiver of a pet policy only where the animal has been individually trained to perform work or perform tasks directly related to the complainant's disability."

FHEO-2020-01 is no longer operative guidance. If your pet policy, your accommodation request form, or your manager training references it, they are out of date. Take advice before changing how you handle requests — federal enforcement posture is one input, and state fair housing law is another that has not necessarily moved.

Occupancy standards- HUD's Keating memo remains the reference point: "the Department believes that an occupancy policy of two persons in a bedroom, as a general rule, is reasonable under the Fair Housing Act." It is rebuttable, and the factors include bedroom size and configuration, age of children, septic capacity, state and local law — and evidence of discriminatory intent, which expressly includes selective enforcement against families with children and limits stated as a number of children rather than persons.

Reasonable modifications- Under the HUD/DOJ joint statement, where a resident requests a structural change — a ramp, grab bars, a widened driveway — "the housing provider must permit the modification, the tenant is responsible for paying the cost." Restoration may be required only for interior modifications, and only where reasonable and requested. Exterior and common-area modifications carry no restoration obligation. That directly affects how you treat a ramp under an unauthorised-structures rule.

Unauthorised structures sit in a federal gap

Sheds, carports, decks, awnings and additions are the most-litigated category in community rules, and the federal position surprises people.

24 CFR §3282.8(j) provides that "an add-on including an attached accessory building or structure added by the retailer or some party other than the manufacturer is not governed by the standards and is not subject to the regulations in this part."

HUD does not regulate them. Which means the governing authority is local building code plus your own community rules — and given the enforceability conditions above, your rules had better be explicit, uniformly applied and properly noticed, because there is no federal standard to fall back on.

There is one federal hook, and it is important: the same section provides that "the addition of any add-on or attached accessory building or structure must not affect the ability of the manufactured home to comply with the standards." A deck bolted through a wall in a way that compromises the home's HUD Code compliance is a genuine safety issue with a federal dimension, not merely a rule violation. That distinction is worth recording, because it changes how urgently the finding should be handled.

Where you may and may not enter

Inspection rights are narrower than most operators assume, and the line is almost always at the skin of the home.

California — Civil Code §798.26(a): "the ownership or management of a park shall have no right of entry to a mobilehome or enclosed accessory structure without the prior written consent of the resident." Management may enter the land at reasonable times for utility maintenance, tree and driveway care, premises maintenance the resident has neglected, and park protection. Entry into the home without consent is permitted only in an emergency or where the home has been abandoned. Written consent is revocable at any time.

Florida — §723.025: "a mobile home park owner has no right of access to a mobile home unless the mobile home owner's prior written consent has been obtained or unless to prevent imminent danger." Entry onto the lot is permitted for utility repair and park protection at reasonable times, "but not in such manner or at such time as to interfere unreasonably with the mobile home owner's quiet enjoyment."

Oregon — ORS 90.725: access runs to the rented space, "not including the tenant's manufactured dwelling or floating home or an accessory building or structure." Non-emergency entry requires "at least 24 hours' actual notice," and the resident may deny consent before or during the attempt.

New York — RPL §233: entry to a homeowner's home without consent only in an emergency.

The operational rule: inspect from the homesite, document from the homesite, and never enter the home or an enclosed accessory structure without written consent. Note that California and Oregon both extend the protection to accessory structures — the shed you are trying to document is itself off-limits inside.

What the violation record must contain

Working backwards from everything above, a defensible violation record needs:

• Homesite ID, so the history survives changes of resident and home
• The specific rule, cited by number to the version in force at the time — not "community rules"
• Date observed, date noticed, date served, and the method of service
• The cure deadline calculated from the state's period
• Photographs, taken from the homesite, dated, and showing enough context to identify the location
• The cure outcome and its date
• Prior notices of the same rule at the same homesite, because Florida's 30-day and 12-month windows, California's three-in-twelve and Oregon's six-month recurrence all run off this
• Comparable findings across the community, because that is what answers a selective-enforcement challenge

Photographs matter, and photographs alone are not enough. A photograph proves a condition existed. It does not prove the rule was in force, properly noticed, uniformly applied, or that the cure period was honoured. Those are record questions.

The last item is the one nobody keeps. Answering "how have we treated this rule everywhere else in the portfolio?" requires the violation history to be queryable across communities, not filed per resident.

How RIOO fits

RIOO is a property management platform built natively on Oracle NetSuite, and the homesite is the primary record — which is what makes violation tracking work at portfolio scale.

Inspections and violations attach to the homesite, so the history survives a change of resident, home or manager. Each violation carries the rule cited by version, the dated notice and service method, and the calculated cure deadline, which is what makes Florida's 30-day window and California's three-in-twelve count readable rather than reconstructable. Findings are routed at the point of capture into operator maintenance or resident compliance, so the two never merge into one queue.

Because the record is queryable across communities, the selective-enforcement question — how has this rule been handled everywhere else — is a report rather than an archaeology project.

See how RIOO handles manufactured housing communities.

Conclusion

Rule enforcement in a manufactured housing community is not a question of finding violations. Violations are easy to find. It is a question of whether the rule is enforceable at all — properly incorporated, substantively reasonable, correctly noticed, and applied the same way to everybody.

Three of those four are settled before an inspector ever drives the community. The fourth is settled by the record you have been keeping, or not keeping, for the last several years.

And the ground moves. HUD's assistance-animal standard changed three months ago. California's statutory subsections were renumbered last year. An enforcement programme that is not reviewed against current law is a programme accumulating defective notices — each one a small liability that only becomes visible when you need the rule to work.

Frequently asked questions

Q1. Are community rules legally binding on residents?
Only if they meet the statutory conditions. Florida deems rules incorporated into the rental agreement. Washington and Arizona each impose six enforceability conditions, including that the rule serve a permitted purpose, be sufficiently explicit, and apply to all residents fairly. Colorado presumes rules imposing costs on homeowners are unreasonable unless management shows necessity.

Q2. How long must I give a resident to cure a rule violation?
It varies widely: California and Florida 7 days, New York 10, Washington 20, Oregon 30, Colorado 90. Check your own statute — these are not interchangeable.

Q3. Can I evict for a repeat violation?
Often, but only on the statute's terms. Florida requires the first notice within 30 days of the first violation and cuts off after 12 months. California removes the notice requirement after three notices of the same rule in 12 months. Oregon removes the cure right where substantially the same conduct recurs within six months.

Q4. What happens if I have enforced a rule inconsistently?
In New York, a rule not applied uniformly carries a rebuttable presumption that it is unreasonable, arbitrary and capricious. In Washington and Arizona, fair application is a condition of enforceability — inconsistent enforcement makes the rule unenforceable, not merely disputable.

Q5. Has the assistance animal rule changed?
Yes. On 22 May 2026 HUD permanently rescinded its 2020 assistance-animal notice and adopted a narrower standard focused on animals individually trained to perform work or tasks related to a disability. Policies written against the 2020 guidance need review, and state fair housing law may differ.

Q6. Can I enter a resident's home to inspect it?
Generally no. California, Florida, Oregon and New York all bar entry into a resident-owned home without prior written consent except in an emergency. California and Oregon extend the protection to enclosed accessory structures. Entry onto the homesite is permitted, with limits and, in Oregon, 24 hours' notice.

Q7. Who regulates sheds and carports added to a home?
Not HUD. 24 CFR §3282.8(j) expressly excludes add-ons from the federal standards, leaving local building code and your community rules as the governing authority. The one federal constraint is that an add-on must not affect the home's ability to comply with the HUD Code.
