A resident sells their 1978 single-wide to a buyer you have already screened and approved. Can you require the home to be removed from the community?

In Washington, no — and you could not have refused to let it in either. In Oregon, no, and the statute names age, size, style and original construction material so there is no argument. In Arizona, no if it was built after 15 June 1976, yes if it was built before — and separately, you could have refused the same home at the front gate regardless of when it was made. In California, only if it fails a specific inspection, because age alone is never sufficient. In Colorado, the sale is protected "regardless of the age of the home." In Florida, the statute says nothing about age at all.

Six states, six answers. And underneath them sits one structural rule that operators consistently miss: what you may do at the front gate is not what you may do to a home already sitting on a homesite. Arizona states that asymmetry expressly. Washington is the only state that closes it.

This guide sets out where each side of that line falls, what a defensible intake policy looks like, and why local ordinances imposing age limits are less reliable than they appear.

General information for operators, not legal advice. This is a per-state question with real penalties for getting it wrong, and the statutes below have been amended recently.

Key takeaways

• Washington prohibits age-based refusal outright — you may not prevent entry or require removal for the sole reason a home has reached a certain age.
• Oregon's bar is the broadest, covering age, size, style, original construction material, and pre-HUD-Code construction.
• Arizona splits intake from resale explicitly — you may bar an older home from moving in, but you may not force removal at resale of a post-1976 home.
• California requires age plus a failed inspection. Age on its own never justifies removal, and the burden of proof sits with management.
• North Carolina and Indiana ban local age ordinances, and Indiana voids existing ones retroactively.
• No FHA, Fannie or conventional financing exists for a pre-1976 home — the certification label is the gate.
• Retroactive age rules do not work in any state examined.

What happened on 15 June 1976 — and one correction

The federal standards apply by production date, not sale date. 24 CFR §3282.8 provides that the part "applies to all manufactured homes that enter the first stage of production on or after June 15, 1976."

A home built the day before carries no HUD certification label and was never subject to the federal construction and safety standards. Standards were strengthened again effective 13 July 1994, principally on wind resistance.

Now the correction, because it matters legally. Operators often say a pre-1976 unit "isn't legally a manufactured home." That is not right as a matter of federal definition. Neither 42 U.S.C. §5402(6) nor 24 CFR §3280.2 puts a date inside the definition — both define a manufactured home by physical characteristics, principally a structure transportable in one or more sections that is eight body feet or more wide or forty body feet or more long.

So the accurate statement is narrower and more useful: a pre-1976 unit meets the federal definition but was never subject to the federal standards and carries no certification label. It is not outside the definition; it is outside the certification regime.

That distinction has practical bite. Some state statutes do draw a legal line at the manufacture date — Arizona's does, as we will see — but you cannot assume the federal definition does the work for you.

The asymmetry that decides everything

Here is the structural finding that organises the rest of this article.

Statutes constrain what you can do to a home already in your community far more than what you can require at the front gate.

That makes sense once you see the interest being protected. A resident who has placed a home on your homesite has an asset they cannot practically move and a tenancy the legislature wanted to protect. Someone applying to bring a 1979 single-wide in next month has neither.

So your intake standard and your resale standard are two different policies, governed by different rules, and an operator who runs one policy for both will either be unlawfully forcing homes out or needlessly letting homes in.

Arizona is the only state we found that states the asymmetry outright. Washington is the only one that abolishes it.

Where you may not refuse: state by state

Washington is the strictest. RCW 59.20.070(9) lists as a prohibited act to "prevent the entry or require the removal of a mobile home, manufactured home, or park model for the sole reason that the mobile home has reached a certain age." Note "prevent the entry" — this is not a resale protection, it is a flat prohibition covering the gate as well.

The exception preserves what actually matters: nothing in the subsection limits a landlord's right to exclude or expel a home "for any other reason, including but not limited to, failure to comply with fire, safety, and other provisions of local ordinances and state laws." Condition and code compliance survive. Age alone does not.

Oregon's bar is the broadest in wording. ORS 90.680(12) prevents a landlord, "because of the age, size, style or original construction material of the dwelling or home or because the dwelling or home was built prior to adoption of the National Manufactured Housing Construction and Safety Standards Act," from rejecting a purchaser's tenancy application or requiring the home be removed. Four grounds closed at once, including the pre-HUD-Code point explicitly.

Colorado protects the sale. Under C.R.S. §38-12-214(2.7)(a), management "shall not interfere with a home owner's right to sell a mobile home... in place or otherwise, to a buyer of the home owner's choosing, regardless of the age of the home," subject to enumerated exceptions around affordability, financial ability, legal compliance and criminal history screening.

Florida protects the sale but says nothing about age. §723.058 bars any rule that "denies or abridges the right of any mobile home owner... to sell his or her mobile home within the park," and bars requiring removal "solely on the basis of the sale thereof." A removal demand grounded on something other than the sale is not, on its face, reached — and the eviction grounds in §723.061 contain no age or condition ground either. Florida is genuinely unsettled here.

Where your state sits is the first thing to establish; the 50-state index is the starting point.

California: age is never enough on its own

California's rule repays close reading because it is the most carefully drafted, and because it shows what a legislature considers a fair standard.

Civil Code §798.73 starts from a prohibition: management "shall not require the removal of a mobilehome from the park in the event of the sale of the mobilehome to a third party during the term of the homeowner's rental agreement." Then four exceptions:

• The unit is not a mobilehome as defined
• A unit 20 feet or more wide and more than 20 years old (25 years if built after 15 September 1971) that fails an inspection against Health & Safety Code §§18550, 18552 and 18605
• A unit under 20 feet wide and more than 17 years old (25 years if post-September 1971) failing the same standards
• A home in "significantly rundown condition or in disrepair," where management bears the burden of demonstrating it and must exercise reasonable discretion

And a procedural gate: management may not require removal "unless the management has provided to the homeowner notice particularly specifying the condition that permits the removal."

Every age threshold is paired with a failed inspection. Age is a screening trigger that opens the door to an inspection; it is never itself the ground. An operator who sends a removal notice saying "your home is 24 years old" has sent a defective notice.

And there is a waiver trap in the companion section. §798.73.5 permits management to require repairs at resale only where the item is not owned and installed by management, is grounded in a local ordinance, state statute or regulation (or a park rule implementing one), and relates to the exterior. Management must supply a written summary of required repairs "no later than 15 business days following the receipt of a request." Miss it, and management "shall be deemed to have voluntarily waived any and all rights to require repairs or improvements," except health and safety mandates.

Fifteen business days, or you lose the right entirely.

Arizona's split, and why it is the clearest model

A.R.S. §33-1452(M) does three things in one subsection, and together they are the clearest statement of the intake/resale asymmetry in American law:

1. On the sale of a home "manufactured after June 15, 1976 to a tenant who is otherwise qualified for tenancy, a landlord shall not require removal of that mobile home from the mobile home park solely because of the age of the mobile home."
2. But a landlord "may require the removal of a mobile home on the sale of the mobile home solely because of the age of the mobile home if the mobile home was manufactured on or before June 15, 1976."
3. And separately, the subsection "shall not be construed to preclude a landlord from prohibiting a mobile home from being moved into a mobile home park solely because of the age of the mobile home without regard to its date of manufacture."

Read the third sentence again. Age-based intake screening is expressly permitted in Arizona, with no 1976 qualifier at all. Age-based forced removal at resale is prohibited for post-1976 homes.

That is the model to think in even outside Arizona: your gate policy and your resale policy are different instruments, and the gate is where your discretion actually lives. The resale side interacts with the resident's protected right to sell, covered in the selling homes guide, and with buyer approval, which is a separate process set out in the resident screening guide.

Local ordinances, and the states that ban them

Many municipalities impose their own age limits on homes moved into the jurisdiction. Real examples:

• A Texas city: "No manufactured home or mobile home may be moved into the city that is more than 10 years old."
• An Arizona city: the date of manufacture "shall not have been prior to ten (10) years from the date of application for a building/location permit."
• An Illinois village: "All replacement manufactured (mobile) homes shall be no more than five years old and shall show proof of age by a title or other legal documentation."

These are convenient for an operator — the municipality does the excluding for you. But they are less durable than they look.

North Carolina bans them. G.S. §160D-910 provides that a local government "may not adopt or enforce zoning regulations or other provisions that have the effect of excluding manufactured homes from the entire zoning jurisdiction or that exclude manufactured homes based on the age of the home." Appearance and dimensional criteria remain permitted. A North Carolina appellate decision struck a county ordinance barring homes older than ten years on exactly this basis.

Indiana bans them and voids the existing ones. IC §36-7-2-12 prohibits a unit from adopting or enforcing a regulation "based on the age of, a mobile home, a manufactured home or an industrialized residential structure," and makes offending provisions "void and unenforceable regardless of when the regulation or provision was originally adopted or imposed."

On federal preemption: we found no case invalidating a municipal age ordinance on federal grounds. The invalidations we located are state-law based. So do not assume a local age limit is federally vulnerable — but do check whether your state has legislated against it, because two have, and more may follow.

The practical risk for an operator: if you have built your intake policy on a municipal ordinance rather than your own community rules, and the state legislature voids that class of ordinance, your policy disappears with it. Write your own rule regardless.

The practical case: financing and fire

Two sourced reasons an age standard is defensible on its merits, independent of preference.

Financing simply does not exist below the line. 24 CFR §203.43f(c)(1) requires that a home eligible for FHA-insured financing be constructed in conformance with the federal standards "as evidenced by a certification label affixed thereto." No label, no FHA loan. Fannie Mae's selling guide requires compliance with the standards established 15 June 1976 and photographic evidence of the HUD data plate or certification label.

An archived HUD reference guide put it more bluntly: "Manufactured houses built before June 15, 1976, must be rejected. No exceptions are allowed." (Archived HUD Homeownership Center reference guide, 2012 — superseded by Handbook 4000.1, cited here for the plain statement rather than as operative policy.)

The consequence for you: a pre-1976 home in your community can only ever be sold for cash or on a chattel note. Your buyer pool is permanently narrower, and so is the resident's exit.

Fire outcomes differ measurably. NFPA's analysis found that "the 2007-2011 death rate was 57% lower for post-standard manufactured home than for pre-standard manufactured homes." NFPA attaches its own caveat, which we repeat because it belongs with the figure: "there are so few deaths in fires with year of manufacture reported among 2007-2011 fires that these estimates should be regarded with caution." Dated data, small sample, directionally clear.

One claim we are not making. Operator guidance routinely asserts that older homes cannot be insured. We could not find a single citable government, regulator or actuarial source quantifying carrier availability for pre-1976 homes — every source is broker or carrier marketing. If that is part of your rationale, source it to your own state insurance department rather than to a trade claim.

On scale: the Housing Assistance Council estimated, from 2014–2018 American Community Survey data, that "an estimated one-fifth of currently occupied manufactured homes were built before 1980." Note the threshold is 1980 rather than 1976, and the data is roughly a decade old. No agency publishes a pre-1976 count.

Retroactive age rules do not work

Can you adopt a rule requiring existing homes over a certain age to be removed or upgraded?

On the evidence, no — and two states foreclose it outright.

Washington is dispositive: the prohibition on requiring removal "for the sole reason that the mobile home has reached a certain age" carries no sale trigger. A standing age rule applied to existing residents is unlawful regardless of whether anyone is selling.

Oregon bars age-based removal requirements at sale.

California's provisions operate only "in the event of the sale," and require particularised written notice of the qualifying condition — so even the age-plus-failed-inspection exceptions are enforceable at resale, not as a standing rule against sitting residents.

Colorado protects the sale regardless of age. Arizona's removal provision is sale-triggered, and its intake carve-out is phrased prospectively — homes "being moved into" the park.

We found no case law or attorney general opinion authorising retroactive application beyond these statutes. And there is a separate problem even where a state is silent: a rule change of this kind must survive the reasonableness and adoption requirements every MH statute imposes on rules, which are covered in the inspections and violation tracking guide. A rule that forces a resident to remove an asset they cannot move is not an easy reasonableness argument.

How to write an intake policy that holds

1. Separate the two policies. One standard for homes entering the community, a different and narrower one for homes changing hands in place.
2. Check your state before writing either. Washington closes the gate policy entirely. Oregon and Colorado close the resale policy. Arizona expressly leaves the gate open.
3. Make condition the ground and age the trigger. Every state that limits age-based refusal preserves condition and code grounds. An intake standard framed as "homes must meet these condition and code requirements, with an inspection required for homes over X years" survives where "no homes over X years" does not.
4. Write the condition standards down, specifically, in the rules — not in a manager's head.
5. Disclose in advance. California's fifteen-business-day waiver provision is the sharpest illustration of a general principle: undisclosed requirements are unenforceable requirements.
6. Never rely solely on a municipal ordinance. Two states have voided that class of ordinance, one of them retroactively.
7. Apply it to everybody. An intake standard enforced selectively is not a standard.
8. Do not apply it backwards. Existing homes are governed by the resale rules, not the gate rules.

The installation and code requirements that a condition standard should reference sit in the moving and installing guide.

How RIOO fits

RIOO is a property management platform built natively on Oracle NetSuite, and the home is an object on the homesite with its own attributes — which is what makes an age and condition policy administrable rather than anecdotal.

Manufacture date, HUD label status and data plate detail sit on the home record, so the population your policy actually touches — pre-1976 homes, homes approaching a resale inspection threshold — is a filter rather than a walk around the community. Intake inspections and condition findings attach to the home with dates, which is the evidence a condition-based standard depends on.

Because the applicable rule version is recorded against each homesite, you can show which standard was in force when a given home entered, which is what separates a policy applied uniformly from one applied to whoever came up last.

See how RIOO handles manufactured housing communities.

Conclusion

The question "can I refuse an older home?" has no national answer, but it has a reliable shape: you have real discretion at the gate and very little once the home is on a homesite.

Build the policy accordingly. Screen hard at intake where your state allows it, framed around condition and code with age as the trigger for inspection rather than the ground for refusal. Then accept that a home already sitting in your community is, in most states, protected — and that the tool for a deteriorating home is a condition standard enforced consistently, not an age rule applied retroactively.

The operators who get into trouble here are not the ones with old homes. They are the ones who wrote "no homes over 20 years" into a rulebook and then tried to apply it to a resident who has lived there since 1998.

Frequently asked questions

Q1. Can a mobile home park refuse to let an older home move in?
It depends on the state. Arizona expressly permits age-based intake screening regardless of manufacture date. Washington expressly prohibits it — you may not prevent entry for the sole reason a home has reached a certain age. Most states are silent on intake, which generally leaves room for a properly adopted rule.

Q2. Can I make a resident remove an old home when they sell it?
Usually not on age alone. Washington and Oregon prohibit it. Colorado protects the sale "regardless of the age of the home." California permits it only where age is combined with a failed inspection against specified Health and Safety Code standards, with the burden on management. Arizona permits it only for homes built on or before 15 June 1976.

Q3. Is a pre-1976 home legally a manufactured home?
Yes, under the federal definition, which turns on physical characteristics rather than date. What a pre-1976 home lacks is the certification label and the federal construction standards, which apply to homes entering first-stage production on or after 15 June 1976. Some state statutes do draw a legal line at that date.

Q4. Can I adopt a rule requiring existing old homes to be removed?
No state examined supports it, and Washington prohibits it outright with no sale trigger. Age-based removal provisions elsewhere are tied to a sale, and a retroactive rule would additionally have to survive the reasonableness and adoption requirements applying to park rules.

Q5. Are local ordinances banning older homes reliable?
Less than they appear. North Carolina prohibits local governments from excluding manufactured homes based on age, and an appellate decision struck a ten-year ordinance. Indiana prohibits such regulations and voids existing ones retroactively. Write your own community rule rather than depending on the municipality's.

Q6. Why does the 1976 date matter so much commercially?
Financing. FHA requires a certification label, which only exists on homes produced on or after 15 June 1976, and Fannie Mae requires compliance with those standards plus photographic evidence of the label or data plate. A pre-1976 home can be sold for cash or on a chattel note, and nothing else.
