Your community rules document is doing more work than most operators realise. It is the basis of every enforcement action, evidence in a fair housing analysis, one of the factors relevant to a 55+ community's intent requirement, and in several states it can only be changed through a procedure set out in statute. A rule adopted incorrectly is a rule you may not be able to enforce.

This article describes general operational practice and cites specific state law only where noted. It is not legal advice. Rule adoption and amendment procedures are set by state law and vary considerably. Have your rules and your amendment process reviewed by counsel in each state where you operate.

Four Jobs the Rules Document Does

Most operators think of community rules as a list of what residents may not do. That is one of four functions, and probably the least important.

1. They are the foundation of enforcement:
   A violation notice has to cite a specific rule. If the rule is vague, or was never properly adopted, or nobody can produce the version in force on the date of the breach, the notice supporting a later termination is weak.

2. They are evidence in a fair housing analysis:
   Rules restricting children's use of common areas, or occupancy standards applied more tightly than the physical characteristics of a home justify, can constitute familial status discrimination regardless of the intent behind them.

3. They are relevant to the 55+ exemption:
   Written rules and regulations are among the factors relevant to demonstrating intent under the federal exemption for housing designed for persons 55 years of age or older.

4. They govern conduct at the point of sale:
   Home-only sales, buyer approval, home appearance standards and replacement home restrictions all typically live in the rules rather than in the lease.

That is a lot of weight for a document that in many communities was written decades ago and has not been read since.

What the Rules Should Cover

A workable set of community rules addresses, at minimum:

Home appearance and maintenance standards, including skirting, steps and decking. Homesite upkeep and what the resident is responsible for. Vehicle parking, storage and inoperable vehicles. Pets, including any size or breed provisions and where they may be exercised. Occupancy, including who may live in a home and for how long a guest may stay. Accessory structures such as sheds, awnings and fences. Use of common areas and amenities. Noise and conduct. Utility responsibilities and who maintains what. Procedures for selling a home in place. And the process for reporting and resolving violations.

Two things to avoid. Rules that restate the lease, which creates two documents saying the same thing slightly differently and an argument about which governs. And rules with no discernible purpose, which are the ones most vulnerable when challenged.

The Reasonableness Requirement

Several states frame the operator's authority in terms of reasonableness rather than as an unlimited right. Texas Property Code § 94.008 gives community owners the right to adopt and enforce reasonable community rules. That single word is where challenges start.

A rule serving a genuine health, safety, appearance or management purpose is defensible. A rule that serves no purpose anyone can articulate is difficult to defend, however clearly it is written and however consistently it is applied.

The practical test: for each rule, can you say in one sentence what problem it solves? If not, it is either doing nothing or doing something you have not examined.

Adopting and Amending: The Procedure Matters

This is where operators most often go wrong, because changing a rule feels like an administrative act rather than a legal one.

Arizona is specific about it. The Mobile Home Parks Residential Landlord and Tenant Act, published by the Arizona Department of Housing, provides that where a community owner adds, changes, deletes or amends any rule, written notice of all such additions, changes, deletions or amendments must be furnished to all tenants thirty days before they become effective, by first class or certified mail.

Note the detail. Thirty days, in writing, to all tenants, by a specified delivery method. A rule change communicated by notice board or newsletter would not meet that on its face.

The Illinois statute also makes the lease relationship relevant. The Mobile Home Landlord and Tenant Rights Act at 765 ILCS 745, published by the Illinois Department of Public Health, provides for a rule or regulation to be effective where thirty days' written notice of its adoption is given to the tenant and the rule is not in violation of the terms and conditions of the lease.

That second limb is easy to overlook. A rule can be properly noticed and still be unenforceable if it contradicts something you already agreed to in the lease. Which means amending rules and amending leases are related exercises, and doing one without checking the other creates a conflict you will discover at the worst moment.

Other states go further. Some require a meeting or a consultation process before implementation, and some impose a waiting period where residents object. Our 50-state index of manufactured housing community laws sets out how differently states approach community regulation, though rule amendment procedures need checking individually.                                                                                     

Where a statute specifies how notice must be given, the method carries the same weight as the content.

Arizona's provision names first class or certified mail. Illinois's Act contemplates written notice provided by hand delivery to the resident's home, by United States mail or recognised courier service, by posting in the community office or clubhouse or other area where residents gather, or by posting on a community bulletin board, depending on the notice in question.

Two states, different permitted methods. An operator running one process across both is running the wrong process in one of them.

Keep proof. Whatever method your state requires, the record of what was sent, when, to whom and how is what you will need if a rule is later challenged. That belongs with the community's dated activity record rather than in a folder someone maintains personally.

The Statement of Policy

Arizona provides an example of a distinct document that some states require alongside the rules.

Under the same Act, before execution of a rental agreement the landlord must provide the tenant with the statements of policy of the community and the date of expiration of each statement. Those statements must be attached to the rental agreement. And the landlord or any successor in interest may not delete or amend any statement of policy while it is in effect.

That last provision is worth reading twice. It binds a successor. If you acquire a community in Arizona, statements of policy in effect at the time of purchase continue to bind you until they expire.

The statements must include, among other things, the classification of the community as a family community or as housing for older persons. If you operate a 55+ community, that classification sits in a document you cannot unilaterally change mid-term, and it interacts with the federal intent requirements the exemption depends on.

Consistency Is the Whole Point

A rule that exists but is enforced selectively is worse than no rule at all, because the inconsistency is documented. Selective enforcement creates evidentiary problems in any later action, and where different treatment correlates with protected characteristics it creates fair housing exposure. The uncomfortable version: an operator who has enforced a rule against three residents and ignored it for twelve others has created a record that works against them.

Two practical consequences.

1. If you will not enforce it, amend it out. A rule nobody intends to apply is a liability dressed as a standard.

2. Apply new rules prospectively and consistently. A rule adopted this year, enforced against new residents but not existing ones, is an inconsistency you have deliberately built in.

Inherited Rules: The Acquisition Problem

Buy a community and you inherit its rules, whatever state they are in.

Three questions to ask in the first month.

1. When were they adopted, and by what procedure?
   If nobody can tell you, treat every rule as potentially vulnerable until reviewed.

2. Which version is actually in force?
   Communities frequently have multiple versions circulating, with residents holding different ones depending on when they moved in.

3. Do the rules and the leases agree?
   Where they conflict, you have a problem that surfaces the first time you try to enforce the rule.

Then read them for content. Rules written decades ago frequently contain provisions that would not be adopted today, particularly around occupancy, children's use of amenities, and community description. If you operate as 55+, terminology in the rules is one of the factors relevant to the intent requirement.

Fixing them requires following the amendment procedure, which is the point of this article. You cannot correct a problematic rule by simply ceasing to enforce it, because the rule remains on the books and the document remains evidence.

A Review Cadence

Rules are not a document you write once.

• Annually, read them. It takes an hour and it is the only way to notice that a rule stopped making sense three years ago.

• On acquisition, review in full against the three questions above.

• When the law changes in a state where you operate, particularly on rent increases, sale approval, occupancy or age restriction.

• When you find yourself unable to enforce something, which is a signal that the rule, the notice, or the record behind it has a problem.

And keep the versions. When a violation is challenged, the question is what the rules said on the date of the breach, not what they say now.

Conclusion

Community rules sit underneath more of a manufactured housing operation than most operators account for. Enforcement rests on them, fair housing analysis examines them, they are among the factors relevant to the 55+ intent requirement, and several states regulate how they may be changed.

Three things worth carrying away.

1. Adopting a rule is a legal act, not an administrative one:
   Arizona's Act requires written notice of any addition, change, deletion or amendment to a rule to be furnished to all tenants thirty days before it takes effect, by first class or certified mail. Illinois requires thirty days' written notice of adoption and that the rule not violate the terms of the lease. Check your states before changing anything.

2. A rule you will not enforce should be amended out:
   Selective enforcement is harder to defend than having no rule, and the record of inconsistency is the thing that gets used against you.

3. Inherited rules are a live liability until reviewed:
   If you cannot say when your rules were adopted, by what procedure, and which version is in force, that is the place to start.

Frequently Asked Questions

1. Can a mobile home park change its rules?
Generally yes, subject to the procedure your state requires. Arizona's Mobile Home Parks Residential Landlord and Tenant Act requires written notice of any addition, change, deletion or amendment to be furnished to all tenants thirty days before it takes effect, by first class or certified mail. Illinois requires thirty days' written notice of adoption and that the rule not violate the terms of the lease. Other states have their own procedures.

2. How much notice does a park have to give before changing the rules?
It depends on the state. Arizona and Illinois both specify thirty days for rule changes, with Arizona also prescribing the delivery method. Some states require a meeting or consultation process, and some impose a waiting period where residents object. Confirm the requirement in each state you operate in.

3. What makes a community rule unenforceable?
Several things. A rule that was never properly adopted under the applicable procedure. A rule that conflicts with the lease, which Illinois addresses expressly. A rule that is not reasonable, where the state frames the operator's authority in those terms as Texas does. And a rule that has been enforced selectively, which creates evidentiary and fair housing problems even where the rule itself is sound.

4. What should community rules cover?
Home appearance and maintenance, homesite upkeep, vehicles and parking, pets, occupancy and guests, accessory structures, common areas, noise and conduct, utility responsibilities, procedures for selling a home in place, and the violation process itself. Avoid restating the lease, and avoid rules whose purpose you cannot state in a sentence.

5. What happens to community rules when a park is sold?
You inherit them. Establish when they were adopted and by what procedure, which version is actually in force, and whether they conflict with the leases. In Arizona, statements of policy in effect cannot be deleted or amended by a successor in interest while they remain in effect, so some obligations transfer direct
