Ask ten manufactured housing operators where their maintenance responsibility ends and the resident's begins, and you will get ten answers. Most of them will involve the word "pedestal," said with more confidence than the law supports.

The confusion is understandable, because manufactured housing sits in a gap. In an apartment, the landlord owns everything and maintains everything. In a single-family rental, the same. In a land-lease community, the operator owns the ground, the roads, the utility infrastructure and the common areas — and a resident owns the building. Two owners, one piece of property, and a line between them that most states have never actually drawn.

Where states have drawn it, they have drawn it differently. Washington fixes the point at the utility hook-up. Colorado fixes it at the pedestal. Florida defers to whatever your lease says. California is the only state that has comprehensively addressed trees and driveways, and it assigns almost all of it to the operator. Washington's MH statute — despite what a good deal of operator guidance claims — does not mention trees at all.

This guide sets out what each side must actually maintain, where the demarcation sits, what changes when the community owns the home, and what it costs when an operator gets it wrong. It is about who is responsible. If you need the process for documenting and enforcing a breach once you have found one, that sits in the inspections and violation tracking guide.

General information for operators, not legal advice. Maintenance duties are state-specific and several of the statutes below have been amended in recent sessions — check your own before relying on any of it.

Key takeaways

• Only two of the six states surveyed fix the utility demarcation point by statute. Washington sets it at the hook-up connection; Colorado sets it at the utility pedestal or pad space. Everywhere else it is your lease.
• Washington's MH statute contains no provision on trees, skirting, carports or awnings. California and Oregon do. Operator guidance that says otherwise is wrong.
• California assigns tree responsibility on individual homesites to management — trimming, pruning and removal, at management's cost.
• A park-owned home is usually governed by a different statute entirely. Washington and Florida both say so expressly, which means you pick up full residential habitability duties for the structure.
• If you are behind a master gas meter, federal law makes you the pipeline operator for everything downstream of it under 49 CFR Part 192.
• Failure is expensive: Colorado authorises penalties up to $5,000 per violation per day, and Florida shifts attorney's fees to the prevailing party.

Why the MH split is different

In conventional residential tenancy, the implied warranty of habitability attaches to the dwelling. The landlord owns the dwelling, so the duty and the ownership sit in the same place.

In a manufactured housing community with resident-owned homes, they do not. You are leasing land, and the habitability question attaches to the space, the utilities you deliver to it, and the common areas — not to the structure the resident put on it.

That is why most states legislated separately for manufactured housing rather than letting the general landlord-tenant act do the work. And it is why the resulting statutes read so differently from one another: each legislature had to invent an allocation from scratch, and they did not converge.

What the operator must maintain

Three patterns are worth pulling out.

Roads are almost always yours. Washington and Colorado name them expressly. This is one of the few items with near-universal agreement, and it is also the largest single deferred-maintenance liability in most acquired communities.

"Vacant spaces" are covered too. Oregon's duty extends to vacant spaces and common areas, and Washington requires vacant lots be kept clear of noxious growth. An operator who lets empty homesites go wild is in breach in both states, regardless of whether anyone lives next door.

California uniquely imposes a repair clock — as soon as possible for health and safety, 30 days otherwise. Most states say "good working order" and leave timing to litigation.

What the resident must maintain

The resident's side is more consistent across states, and narrower than operators generally assume.

Florida (§723.023) requires the resident to keep the homesite "clean, neat, and sanitary, and maintained in compliance with all local codes," and to obtain written approval before any exterior modification or addition to the home.

Washington (RCW 59.20.140) requires the resident to keep the homesite "as clean and sanitary as the conditions of the premises permit," not to damage landlord property, and "not permit a nuisance or common waste."

Oregon (ORS 90.740) is the most detailed. The resident must install the home and "any accessory building or structure" in compliance with applicable law and the rental agreement, keep the space "free from all accumulations of debris, filth, rubbish, garbage, rodents and vermin," and "water and mow or prune any shrubbery or grass."

Arizona (A.R.S. §33-1451) requires the resident to "exercise diligence to maintain that part of the premises that the tenant has rented in as good condition as when the tenant took possession."

Notice what is almost entirely absent: the home itself. With the exception of Florida's exterior-modification approval requirement, these statutes say remarkably little about the condition of the structure. The resident owns it, so its condition is governed by your community rules rather than by statute — and community rules are only as good as the record showing they were applied consistently.

The demarcation point

This is the question operators actually ask, and the honest answer is that most states have not answered it.

Washington answers it directly- RCW 59.20.130(6) provides that "maintenance responsibility shall be determined at that point where the normal mobile home, manufactured home, or park model utilities 'hook-ups' connect to those provided by the landlord or utility company." Everything up to the connection is yours; everything past it is the resident's.

Colorado answers it directly- §38-12-212.3 obligates the landlord for lines "owned and provided by the landlord to the utility pedestal or pad space," and requires water furnished to each pedestal or pad space. Same principle, different physical marker.

Oregon answers it functionally- ORS 90.730 requires each of sewage, water and electrical to have "a connection to the space approved under applicable law at the time of installation and maintained in good working order." The duty runs to the connection.

Florida does not answer it- §723.022(4) obligates the park owner only for utility connections and systems "for which the park owner is responsible" — which is a circular reference back to your lease and prospectus. If those documents are silent or vague, you will be arguing about it.

We found no state agency guidance establishing a general demarcation rule beyond the above- Everywhere other than Washington, Colorado and Oregon, this is a contract question.

The practical consequence: if you operate in a state without a statutory demarcation, the lease and prospectus are doing load-bearing work, and most of them do it badly. Language like "resident is responsible for utilities serving the home" resolves nothing when a water line fails eight feet underground between the pedestal and the riser. Specify the physical marker — meter, pedestal, riser, point of connection — and specify who bears excavation.

The master meter changes everything

If your community buys gas at a master meter and distributes it, federal law treats you as the operator of a gas distribution pipeline system.

49 CFR §192.3 defines a master meter system as "a pipeline system for distributing gas within, but not limited to, a definable area (such as a mobile home park, housing project, or apartment complex) where the operator purchases metered gas from an outside source for resale through a gas distribution pipeline system."

That single definition pulls you into 49 CFR Part 192 — leak surveys, operator qualification, damage prevention, emergency response plans, records. This is not a landlord-tenant question and no lease clause escapes it. It is federal pipeline safety regulation, and the demarcation debate above is irrelevant to it: whatever your lease says about who maintains what, the regulatory obligation for the system downstream of the master meter is yours.

The same structural principle applies to master-metered water and electric, though under different regimes. If you are unsure whether your community is master-metered on any utility, that is the first thing to establish — not the second.

Trees, driveways and the things nobody assigned

Here the states diverge sharply, and a widely repeated claim in operator guidance turns out to be false.

California is the most explicit, and assigns most of it to you- Civil Code §798.37.5 makes management solely responsible for trimming, pruning or removing trees on individual rental spaces and in common areas, and for bearing the cost. Management must also maintain, repair, replace and seal driveways it installed, including damage from tree roots. Driveways the homeowner installed are the homeowner's. And "no homeowner may plant a tree within the mobilehome park without first obtaining written permission from the management."

Oregon splits trees by hazard- ORS 90.727 provides that the landlord "shall maintain a tree that is a hazard tree, that was not planted by the current tenant, on a rented space," while "a tenant is responsible for maintaining the trees on the tenant's space in a manufactured dwelling park at the tenant's expense." There is no landlord duty to maintain a tree for aesthetic reasons, and work on trees of eight inches diameter or more requires a licensed landscape construction professional. ORS 90.730 separately makes the landlord responsible for completing landlord-provided improvements such as carports, driveways and sidewalks.

Washington says nothing-A full-text search of RCW 59.20 returns no mention of trees, hazard trees, skirting, carports, awnings or accessory structures. Operator guidance that cites Washington on trees is citing something that is not there.

Skirting, steps, awnings and sheds are unassigned almost everywhere- No state statute we located allocates them by name. Oregon puts installation and code compliance of accessory structures on the resident. Florida requires operator approval before exterior modification. Beyond that, these are community-rule matters — which means your rules document is the only thing standing between you and an argument.

If you operate across state lines, this cannot be standardised into one national policy. The 50-state operator's index sets out where each state sits.

A park-owned home changes which law applies

This is the most consequential distinction in the article, and it is frequently missed.

When you rent the home as well as the site, you are usually no longer operating under the manufactured housing statute at all.

Washington states it expressly: RCW 59.20.040 provides that "rentals of mobile homes, manufactured homes, or park models themselves are governed by the residential landlord-tenant act, chapter 59.18 RCW." You have picked up the full RCW 59.18 habitability duty for the structure — roof, plumbing, heating, weatherproofing, the lot.

Florida states it expressly: §723.002 provides that Chapter 723 "shall not be construed to apply to any other tenancy, including a tenancy in which both a mobile home and a mobile home lot are rented or leased by the mobile home resident." Park-owned home rentals fall under Chapter 83, Part II — ordinary residential tenancy law.

Oregon reaches a similar result through the structure of ORS 90.505, though we could not verify express statutory language saying so.

So an operator running a mixed community may be subject to two different statutes simultaneously, with different maintenance duties, different notice periods and different remedies, on adjacent homesites. That is not a theoretical problem — it is a reason the park-owned versus tenant-owned decision carries operational cost beyond the maintenance budget, and a reason your records need to know which regime each homesite is under.

What happens when you do not maintain

Colorado's per-day structure deserves particular attention. A water line you did not fix for sixty days is not one violation — it is potentially sixty. And Florida's fee-shifting changes the economics of small disputes entirely: a resident with a valid $800 repair claim can pursue it because their lawyer gets paid if they win.

Where this belongs in your records

Maintenance allocation is a records problem before it is a repair problem. When a dispute arrives, the questions are always the same:

• Which statute governs this homesite — the MH act, or the general residential act because we own the home?
• Where is the demarcation for this utility on this site, and what document establishes it?
• Was this improvement installed by us or by the resident? California makes this dispositive for driveways; the same logic runs through carports, sheds and steps everywhere else.
• Who planted that tree, and when? Oregon's hazard-tree duty turns on whether the current resident planted it.
• What did we do, and when did we do it? Colorado's per-day penalty and Washington's "reasonable time" standard both run on dates.
• Have we treated comparable situations the same way?

Very few operators can answer all six for a homesite they took on three owners ago. That is the actual exposure — not the repair cost, but the inability to demonstrate where the line was and that you stayed on your side of it. The wider records architecture this sits inside is covered in the community operations guide.

For scale: UMH Properties reported community operating expenses of $95.3 million in FY2025 against rental and related income of $226.7 million — a 42.0% community operating expense ratio across 27,086 developed homesites, or roughly $3,500 per homesite per year all-in. Treat that as directional only: roughly 11,000 of those homesites carry company-owned rental homes, so the ratio reflects a heavy park-owned mix and overstates what a pure land-lease operator should expect. Neither UMH nor Equity LifeStyle breaks out repairs and maintenance separately, so a clean industry R&M-per-homesite figure does not exist in public filings.

How RIOO handles it

RIOO is a property management platform built natively on Oracle NetSuite, and the homesite is the record — which is what makes the allocation question answerable.

Each homesite carries its governing regime (MH act or general residential, driven by whether the home is park-owned), its utility demarcation reference, and an improvement register recording what was installed, by whom, and when. Maintenance work orders attach to the homesite rather than to a generic unit, so the history survives changes of resident, changes of home and changes of ownership.

Because the accounting is native NetSuite, maintenance cost sits against the homesite and the property in the same ledger as the revenue from it — which is what turns a repair log into an operating expense analysis rather than two disconnected records.

Conclusion

The maintenance line in a manufactured housing community is not a matter of custom or common sense. In two of the six states surveyed it is fixed by statute at a specific physical point. In one it is fixed functionally. In the rest it is whatever your lease says — which for most operators means it is unsettled.

Three things follow. If your state fixes the point, know where it is. If it does not, fix it yourself in the lease with a physical marker and an excavation clause. And if you own homes as well as sites, understand that you are probably operating under two statutes at once, with the heavier set of duties attaching to the homes you own.

The operators who lose these disputes are rarely the ones who neglected a repair. They are the ones who could not show where the line was.

Frequently asked questions

Q1. Where does the operator's responsibility for utility lines end?
In Washington, at the point where the home's utility hook-ups connect to those provided by the landlord or utility company. In Colorado, at the utility pedestal or pad space. In Oregon, at the approved connection to the space. In most other states there is no statutory demarcation and the lease controls.

Q2. Who is responsible for trees on a homesite?
It depends on the state. California assigns trimming, pruning and removal on individual spaces to management, at management's cost. Oregon makes the landlord responsible for hazard trees not planted by the current resident, and the resident responsible for the rest. Washington's MH statute does not address trees at all.

Q3. Who maintains skirting, steps, awnings and sheds?
No state statute we located assigns these by name. Oregon puts installation and code compliance of accessory structures on the resident; Florida requires operator approval before exterior modification. Beyond that these are community-rule matters, which is why the rules document needs to be specific.

Q4. Does the operator become responsible for the home if the community owns it?
Yes, and usually under a different statute. Washington expressly routes park-owned home rentals to the general residential landlord-tenant act; Florida expressly excludes them from Chapter 723 and routes them to Chapter 83, Part II. In both cases you assume full habitability duties for the structure.

Q5. What if we distribute gas from a master meter?
Federal pipeline safety regulation applies. 49 CFR §192.3 defines a master meter system to include a mobile home park purchasing metered gas for resale through a distribution system, which makes you the operator of that system under Part 192. No lease term changes this.

Q6. What can a resident do if the operator does not maintain?
It varies. Washington allows repair-and-deduct up to one month's rent per year after two bids. Oregon allows procure-and-deduct, damages, or substitute housing for essential service failures. Colorado authorises agency penalties up to $5,000 per violation per day. Florida shifts attorney's fees to the prevailing party.
