Mobile Home Park Regulations: Key States Investors Must Understand

Mobile home park regulations by state: rent caps, notice requirements, and tenant protections.

My Real Estate Calculator Editorial
Data-driven analysis for real estate investors.

A Texas investor bought a California MHP and implemented the same rent increase strategy that worked back home. Six months later: $180,000 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 10 most important regulatory markets for MHP investors, organized by investor-friendliness. Use it to understand where you're investing and what rules apply.

State-by-State Analysis

Tier 1: Landlord-Friendly States

These states have minimal rent restrictions and favor property owner rights.

Texas (5,176 parks as of 2024 — largest MHP market)

FactorStatus
Rent controlProhibited statewide since 1990s
Maximum increaseNo limit
Notice required30 days (month-to-month)
Eviction restrictionsMinimal
The reality: Texas is the most landlord-friendly major market. Cities and counties cannot implement rent control. Rent increases are limited only by lease terms and market tolerance. Investment implication: Maximum operational flexibility. Returns depend on market dynamics, not regulatory caps.

Arizona

FactorStatus
Rent controlProhibited by state law
Maximum increaseNo limit
Notice required30 days (month-to-month)
Eviction restrictionsMinimal
The reality: State law explicitly prohibits cities and towns from creating rent control. Increases limited only by discrimination and retaliation prohibitions. Investment implication: Flexible market similar to Texas. Growing Sun Belt demand supports rent growth.

Florida (3,785 parks as of 2024 — third largest market)

FactorStatus
Rent controlBanned statewide since 1977
Maximum increaseNo limit (exception: West Palm Beach)
Notice required30 days
Eviction restrictionsMinimal
The reality: Statewide rent control ban covers most of the state. West Palm Beach is the notable exception—limiting MHP increases to 5% or CPI (whichever is greater) with 90-day notice.

Investment implication: Favorable regulations, but significant climate and insurance risks (covered separately).


Tier 2: Moderate Regulation States

These states have procedural requirements without strict rent caps.

Colorado

FactorStatus
Rent controlNo cap on amount
Maximum increaseUnlimited, but procedural requirements
Notice required60 days
Increase frequencyOne per 12 months maximum
RegistrationPark must be registered with state
Key requirement: The park must be actively registered with the Division of Housing at the time of rent increase notice, or the notice is invalid. Dispute resolution: Mobile Home Park Oversight Program (MHPOP) handles tenant complaints. Investment implication: No rent cap, but strict procedural compliance required. Administrative burden higher than Texas/Florida.

New York

FactorStatus
Rent control6% cap unless hardship approved
Maximum increase6% above current rent
Notice requiredVaries by lease type
Eviction restrictionsStrong tenant protections
Dispute processCourt-based, tenant can challenge
Key provisions: Investment implication: Most restrictive East Coast market. Underwrite conservatively with 6% cap assumption.

Tier 3: Tenant-Protective States

These states have significant rent restrictions and tenant rights.

California (~4,000 parks as of 2024 — second largest market)

FactorStatus
Statewide rent controlNo statewide cap
Local rent controlCommon — varies by jurisdiction
Notice required90 days
Eviction restrictionsOnly 7 allowable reasons
RegistrationRequired in many jurisdictions
The complexity: California has no statewide MHP rent cap, but many cities and counties have local rent stabilization ordinances (RSOs):
Jurisdiction2024-2025 Limit
Los Angeles County4% maximum
Mountain View1.6% (2025)
San JoseCPI-based
Other citiesVaries widely
Eviction protections: The Mobilehome Residency Law (MRL) limits eviction to 7 specific reasons. Lease expiration is NOT grounds for eviction if tenant owns their home. Investment implication: Research specific city/county rules before buying. Some California markets are effectively impossible for value-add strategies; others have no local restrictions.

Washington

FactorStatus
Rent control5% maximum annual increase (MHPs)
Grace periodNo increases in first 12 months
Notice required90 days written notice
General housing7% + inflation or 10%, whichever lower
Key protections (HB 1217, effective May 2025): Investment implication: The 5% MHP-specific cap is more restrictive than general housing. Underwrite conservatively.

Oregon

FactorStatus
Rent control10% maximum annual increase
Pending legislationHB 3054 (CPI-based cap proposed)
Notice requiredPer state law
Eviction restrictionsStrong tenant protections
Current status: 10% cap is less restrictive than Washington's 5%, but proposed legislation would tie increases to CPI (typically 2-4%). Investment implication: Monitor HB 3054. If passed, Oregon becomes significantly more restrictive.

Federal Scrutiny

Senator Maggie Hassan's 2024 investigation targeted six major MHP firms:

The investigation requested internal documents on business practices and impact on residents. Federal legislation remains unlikely, but scrutiny creates reputation risk and may encourage state action.

Federal scrutiny of MHP operators has increased significantly. While legislation remains unlikely, the reputational risk for aggressive rent practices is real—and may encourage state action.

State-Level Momentum

States considering new protections (as of 2024-2025):

The trend is toward more protection, not less. Build this into long-term planning.

Resident-Ownership Models

Several states are promoting resident-owned communities (ROCs) as an alternative to investor ownership:

This doesn't affect existing investor-owned parks directly but signals policy direction.


How Regulation Affects Your Investment Thesis

Due Diligence Checklist

Before buying in any market:

Do not rely on general information. Laws change, and local regulations can differ significantly from state law.


Analyze Deals in Your Target Market

Understanding regulations is essential—but so is running the numbers with realistic rent growth assumptions. In restrictive states, model conservatively (cap rate or below). In landlord-friendly states, you have more flexibility.
