Case #/Title:  
ES-2025-02/Mobile Home Parks/Recreational Vehicle Parks 
Supervisor Districts: 
All Districts 
Applicant: 
Maricopa County Environmental Services Department (Department) 
Request: 
Approve proposed revision to Maricopa County Environmental 
Health Code (MCEHC), Chapter IX, Section 1-9. 
Support/Opposition: 
A stakeholder workshop was held on May 22, 2025.  One stakeholder 
spoke in support of the case as their park would no longer need a 
permit. No other comments, questions, or concerns were received for 
this case.  
Department 
Recommendation: 
The Department recommends that the Board of Supervisors (BOS) 
approve the proposed MCEHC revision.  
BOH  
Recommendation: 
The Board of Health (BOH) voted unanimously to approve the 
Department’s proposed revision and proceed according to the EROP 
expedited process.  
Executive Summary: 
This case aligns the MCEHC requirements for mobile home parks and 
recreational vehicle parks with the Arizona Administrative Code 
(A.A.C.). Currently, requirements in MCEHC are more restrictive than 
those outlined in the A.A.C. This alignment will result in deregulation 
by no longer requiring permits and routine inspections for mobile 
home parks that do not offer space for recreational vehicles. Parks 
that offer space for recreational vehicles will continue to be permitted 
and inspected according to the requirements outlined in the A.A.C., 
MCEHC, and in accordance with delegated responsibilities. It should 
be noted that the proposed changes will not impact the Department's 
ability to address public health nuisances in any mobile home park 
should they occur.  
1

The proposal does not increase fees; it updates the language found in 
MCEHC. 
In accordance with the Maricopa County Resolution, “Moratorium on 
Increased Regulatory Burdens,” the County Manager authorized the 
Department to proceed with this case on April 1, 2025, and the 
Maricopa County Board of Supervisors (BOS) was briefed on April 30, 
2025. 
The Department conducted a stakeholder workshop on March 22, 
2025. On July 28, 2025, the Department presented a Staff Report for 
this case to the Board of Health (BOH), at which time the BOH 
approved this case to proceed on the EROP expedited process for the 
BOS to adopt this proposed Department revision.

The department recommends that the Board of Health approve the

Park section of the MCEHC for consideration by the Board of Supervisors.    
Currently, requirements in MCEHC for mobile home parks are more 
restrictive than those outlined in the Arizona Administrative Code 
(A.A.C). The Department proposes aligning MCEHC requirements with 
the A.A.C. This alignment will result in deregulation by no longer

do not offer space for recreational vehicles. Parks that offer space for 
recreational vehicles will continue to be permitted and inspected

Background
Mobile Home Parks/Recreational Veh icle Parks in 
Maricopa Co unty 
Inspection and regulation of Recreational Vehicle Parks are delegated to the 
Maricopa County Environmental Services Department (Department) by the Arizona 
Department of Health Services (ADHS). 
Inspection and regulation of Recreational Vehicle Parks ensures:
Proper management and operation of the park, including all water supply
provided is safe, all sewage and human excreta is disposed of properly
The grounds are free of public health nuisances
Background
Mobile Home Parks/Recreational Vehicle Parks in 
Maricopa Co unty 
Currently, requirements in the Maricopa County Environmental Health Code 
(MCEHC) for mobile home parks are more restrictive than those outlined in the
Arizona Administrative Code (A.A.C.)
Mobile home parks, as defined in MCEHC, are not regulated in the A.A.C. nor  are 
they delegated by ADHS 
The Department is proposing changes to the MCEHC to align mobile home parks
and recreational vehicle park requirements with the A.A.C. This alignment will 
result in deregulation by no longer requiring permits and inspections for mobile 
home parks that do not offer space for recreational vehicles. 
Purpose of Proposed Code Change
Mobile Home Parks/Recreational Veh icle Parks in 
Maricopa Co unty 
If approved, the changes to the MCEHC would include:
Adopt Title 9, Chapter 8, Article 5 Sections 501 through 507 of the Arizona 
Administrative Code as the Recreational Vehicles and Parks Code of Maricopa 
County.
Eliminate Chapter 9, Sections 2 through 9 of the MCEHC.
Approximately 1/2 of the 467 permitted mobile home parks do not provide space 
for recreational vehicles and will no longer require permitting and inspection.

Minutes*: Amanda Bond covered the Enhanced Regulatory Outreach Program (EROP) process and 
how stakeholders can stay informed on this and other upcoming cases.  Brian Knisley explained 
that the Maricopa County Environmental Services Department (Department) proposes aligning 
Maricopa County Environmental Health Code (MCEHC) requirements with the Arizona 
Administrative Code (A.A.C.). This alignment will result in deregulation by no longer 
requiring permits and routine inspections for mobile home parks that do not offer space for 
recreational vehicles. Parks that offer space for recreational vehicles will continue to be 
permitted and inspected according to the requirements outlined in A.A.C., MCEHC, and in 
accordance with delegated responsibilities. Andy Linton added that the state changed their 
rules in 2019, and Pinal County aligned their local code with the state code. While Pinal 
County had one mobile home park that was opposed to the change, they were able to keep 
their permit by offering Recreational Vehicle spaces.  
Michelle Selbab says she appreciates the permit being eliminated, and so does the owner. 
Meeting adjourned.
