A Texas investor bought a California MHP and implemented the same rent increase strategy that worked back home. Six months later, he was still paying for it in legal fees and tenant settlements. What's legal in Texas may violate California law—and getting regulations wrong can destroy your entire investment thesis.
This guide covers the regulatory markets that matter most for MHP investors. Use it to understand where you're investing and what rules apply.

Start by nailing down the legal relationship you actually have — owning a home and renting the site under it is a different relationship from renting the home itself — then check the rules that apply to the specific action you want to take. Federal requirements, state law, local ordinances, permits, leases, and financing documents can each add a requirement, so learning one of them doesn't tell you what you're allowed to do at your park. The examples below were checked against official sources on September 8, 2026: research starting points, not a complete fifty-state survey, and definitely not instructions for issuing a legal notice.
Identify the tenancy before applying a rule
First, write down what each resident actually has. Do they own the home and rent a site? Rent a park-owned home? Something else? Then check how your state defines those arrangements, along with the property's size, classification, and any exemptions.
A state might handle site tenancies under a manufactured-housing statute while applying different rules to a rental home. If you've got both, you may need to run the analysis twice.
When you bring this to counsel, bring the documents: the leases, the rules, the notice history, the site information, and what you're proposing to do. "Is this a landlord-friendly state?" is too broad a question to build a rent forecast on.
Separate the amount of a change from its process
Say you're planning a rent increase. That's five separate questions:
- Does a limit apply, and how is the allowable amount calculated?
- When may an increase occur, and how often?
- What written notice, wording, delivery method, and waiting period are required?
- Are utilities, fees, or service changes included or separately regulated?
- Do the lease, local rules, financing terms, or resident rights add requirements?
Keep the amount and the process in separate boxes. Staying under a percentage limit doesn't excuse you from the notice requirement. Perfect notice doesn't rescue an increase that was never allowed.
Selected state examples show why the details matter
Washington: distinguish manufactured-home site tenancies
Washington's Attorney General explains that the rent-stabilization law sets a 5% maximum annual increase for covered manufactured/mobile-home site tenancies. The summary also covers the first twelve months of tenancy and advance written notice. Confirm which provisions, exceptions, and process apply to your property. Washington Attorney General
Watch out for one easy mix-up: the state's general residential percentage is a different rule. Figure out which framework covers your tenancy before you reach for a number.
Oregon: facility size changes the published 2026 limit
Oregon's Office of Economic Analysis lists a 6% maximum for 2026 for tenancies subject to ORS 90.600(1) in facilities with more than 30 spaces. For covered facilities with 30 or fewer spaces, it lists 9.5%, along with specified other tenancy types. The page defines facilities to include manufactured dwellings and marinas.

Site count changes the answer, so your spreadsheet needs the property's classification and space count along with the rules for the right year. Read the underlying statutes, exclusions, timing, and notice requirements before you plug in a published percentage.
Florida: notice involves more than a rent number
Florida Statutes Section 723.037 requires at least 90 days' written notice for specified lot-rent increases, reductions in services or utilities, and rule changes under the chapter. The section also spells out who has to receive notice and lays out a process that goes beyond announcing a new payment. Florida Section 723.037
Confirm that Chapter 723 applies and work through every procedural step. A generic thirty-day rental notice won't carry over into a covered park transaction or operating plan.
California: check state law and the local ordinance
California Civil Code Section 798.30 requires management to give a homeowner at least 90 days' written notice before a rent increase takes effect. Local rules and other provisions need their own review. California Civil Code Section 798.30
Work from current statutory and local materials with counsel, especially around rent regulation, lease terms, exemptions, or closure. An older lease or a general residential rule may not speak to the question in front of you at all.
New York: increases and their justification need review
The New York Attorney General's manufactured-home tenant guide describes limits on increases and the circumstances that call for extra justification or procedure. It also covers rights that have nothing to do with rent, including leases and services. New York manufactured-home tenant guide
Read the process that applies to what you're doing. An exception or hardship mechanism exists for specific situations. It isn't a green light for a routine increase. Check local requirements and the current law for your intended action.
Texas: read the manufactured-home tenancy chapter
Texas Property Code Chapter 94 covers manufactured-home tenancies. Read its definitions and requirements next to your agreement and local rules. No rent cap doesn't mean no rules. Notices, lease obligations, utilities, and termination procedures are all still in play. Texas Property Code Chapter 94
Review obligations that do not appear in the rent forecast
Your rulebook should reach well past rent. Cover licenses and registration, water and wastewater responsibilities, utility billing, fees, deposits, maintenance, home sales, rule enforcement, renewal, termination, and resident communications.
Before a purchase, sale, or closure, look for resident notice, purchase, relocation, or other rights. Find out what triggers them and how much time they take, then commit to a transaction schedule.
If the park has agency financing, contractual resident protections come along with it. Fannie Mae publishes tenant site lease protections for its MHC financing, and those sit alongside applicable law rather than replacing it. Fannie Mae lease protections
One more layer that a state comparison won't cover: fair housing and your other federal obligations. Have qualified counsel look at screening, accommodations, notices, and how you administer rules.
Translate the rules into a realistic cash model
Let's put timing in dollars. Say your plan assumes a lawful $25 monthly increase across 36 occupied sites. Over a full twelve months, that's $10,800 in additional scheduled rent, before collection effects or related costs.
Now run it the way a notice period might force you to. The change can only take effect for the last six months of the modeled year. Same increase, and it produces $5,400. The monthly rent is identical. Timing moved the number, and timing is the part you can plan around once you've confirmed the rules.
To be clear, the example doesn't tell you a $25 increase is allowed at your park. Confirm the amount, timing, process, lease terms, and applicable rules first, then put it in the forecast.
The park analysis guide helps you keep today's income separate from tomorrow's operating plan.
Maintain the rulebook as an operating document
For each important action, record five things: the governing source, whether it applies, the required steps, who's responsible, and the date you last reviewed it. Keep copies of the documents and proof that you delivered or completed what was required.
Then revisit the record whenever the law changes, a lease renews, ownership changes, financing is modified, or you propose a different use. Let counsel sort out conflicts and any interpretation you're unsure about.
The first-90-days guide helps carry this work through the ownership transition, and the resident-service guide shows how clear communication supports all of it.
Frequently asked questions
Which state is best for mobile home park investors?
No state label can tell you whether a property fits your resources. Compare documented income, local demand, infrastructure, operating obligations, financing, and the rules that apply to that specific property. Price and execution matter every bit as much as regulation.
Can I raise rent immediately after buying a park?
Don't count on it. A sale doesn't reset leases, notice history, timing restrictions, or resident rights. Review the existing arrangements and the applicable law before you plan a change or mention it to anyone.
Do the same rules apply to park-owned homes and site rentals?
Often not. The resident's ownership arrangement and the statutory definitions can put you in a different framework. If you run both, plan on separate lease and compliance processes.
Can a lease waive statutory resident protections?
Maybe not, so don't build on that assumption. Have counsel check enforceability under the applicable law and any financing requirements. A signature makes a document signed. It doesn't make every provision in it valid.
Take the state your next deal sits in, spend an afternoon with its actual statute and your actual leases, and write down what you find with today's date on it. That one page will serve you better than any fifty-state chart, and your attorney will bill you less for reading it.
