According to testimony before the Senate Committee on Housing and Human Services, many individuals are facing challenges with housing access, and manufactured housing has traditionally been an option for attainable housing; however, homeowners of manufactured homes are reportedly experiencing unjustifiable rent increases and declining infrastructure in manufactured housing communities. It has been suggested that licensing standards for the communities be updated and that LARA be given additional tools to enforce the proposed standards for the improvement of the manufactured homes market.

The bills would have a significant but indeterminate fiscal impact on State government and an indeterminate fiscal impact on local units of government.


Senate Bill 486 would restructure the licensing system for mobile home parks and related licenses under the Mobile Home Commission Act. Currently, the term for a mobile home park license is three years. The bill would revise this period to one year, beginning on January 1, 2025. Licenses issued on or before December 31, 2022, would expire on December 31, 2024. As of October 2023, approximately 1,000 licenses would fall into that expiration category. Less than 1% of these licenses are for seasonal parks.


The changes to the license fees included in the bill are shown in the table below:


Proposed Changes Under SB 486


Current Law

(every three years)

Oct. 1, 2023, to Dec. 30, 2024


On and after Dec. 31, 2024


Mobile Home Park




Per site fee for home sites in excess of 25




Mobile Home Park, Seasonal




Per site fee for home sites in excess of 25





These license fees are deposited into the Mobile Home Code Fund. The Fund is used for the Bureau of Construction Codes, the Bureau of Fire Services, and other overhead expenses within LARA upon appropriation by the Legislature. The proposed changes likely would result in significantly increased revenue to LARA, although the exact amount would depend upon the number of licenses applied for and that met the new criteria required under the bill. Based on the core annual fees alone and current license counts, it is likely that LARA would collect $500,000 or more in additional annual revenue under the bill if the number of licensees did not change significantly. It is possible that due to the more stringent requirements, fewer individuals would qualify as licensees; however, the increase in fees likely would offset this loss.


The bill also would create a new provisional license for mobile home parks. Beginning July 1, 2024, a mobile home park not previously licensed would need a provisional license to operate. No fee for a provisional license is specified in the bill.

The bills would require LARA to employ "an appropriate number" of qualified employees to implement and enforce the Act as well as the rules promulgated under it. Although LARA currently enforces and administers the Mobile Home Commission Act and most related rules, the changes made under the bill, as well as the new and revised rules that could be required under it, likely would necessitate one or more additional Full Time Equivalents (FTE) and appropriations to fully satisfy the Department's duties and responsibilities. The average cost of an FTE, including benefits, is $137,500 per year. The number of employees needed would depend partially on the number of applicants who qualify under the new licensee parameters.

Additional duties for LARA would include additional inspections. Senate Bill 487 would allow LARA to contract this work out to local governments, which could bear minor additional costs related to the development and administration of these agreements; however, in the absence of such an agreement, the cost of these inspections would fall to LARA. As described above, it is possible that LARA could need to engage additional inspectors.


The Department also would have to establish a publicly accessible database of owners that would contain key licensing information, by July 1, 2025. It currently has such a database but is possible that it could need additional funding to ensure compliance with the bills. The Department could charge a $100 processing fee if an owner failed to update contact information as required under the bill.


The Department could elect to conduct a background check on an applicant or a person who holds a beneficial interest in a park. The number of background checks performed could increase due to the expansion of the definition of a person with beneficial interest included in the bill. The Department could use the background system maintained by the Department of State Police for this purpose. The cost to conduct a single search is $10. The bill does not specify whether LARA would charge the applicant or person with interest for the cost of the search.


Senate Bill 486 would require LARA to revise the Mobile Home Code by July 1, 2025. This process likely would be covered by existing appropriations, but additional staff time and administrative costs could increase expenditures. The Department would need to consult with additional entities to develop these recommendations.


Senate Bill 486 also would allow LARA to impose an administrative fine of not more than $5,000, following appropriate steps as required under the Administrative Procedures Act, if a licensed owner failed to post a copy of the owner's license as required under the bill. It also would require the payment of all previously assessed fees and administrative fines for an individual to be considered to have completed an application. The Department could assess a late renewal fee of up to 50% of the license application fee if a renewal were submitted more than seven days after the expiration of a license. All revenue from fines assessed under the Mobile Home Commission Act is deposited into the Mobile Home Code Fund.


Senate Bill 489 retains the current $50,000 cap on civil fines assessed for violations of the Act; however, it would require a fine of up to $100,000 to be assessed if an unlicensed owner of a mobile home park did not apply for licensure within a 30-day period after being notified by LARA that the owner was required to obtain a license. The bill directs LARA to refer cases of nonpayment to the Attorney General for possible civil action.


The revenue from fines would depend upon the number of violations found and fines levied.


The Department of Environment, Great Lakes, and Energy (EGLE)


In addition to promulgating rules, EGLE could enter into agreements with local governments


to enforce rules under its purview. While any costs would depend upon the specific details of any such agreement, it is likely that the bills would have a negligible fiscal impact on EGLE.


Department of State


The bill would have a negligible fiscal impact on the Department of State. The provisions that would require the Department to send out notifications of abandoned mobile homes would require some additional staff time, but those costs likely would be absorbable within annual appropriations.




The bills would not have a significant fiscal impact on district or circuit courts. The addition of certain prohibitions against unlicensed park owners potentially could reduce district court caseloads, while the provisions that direct certain cases to circuit courts could result in some additional circuit court hearings; however, these costs likely would be absorbed by current appropriations levels.


Attorney General


The bills could result in minor costs to the Department of Attorney General should LARA decide to bring a civil action against individuals who neglected to pay the new $100,000 fine for failure to acquire a license; however, the Attorney General may exercise authority over similar violations under current law. The Department of Licensing and Regulatory Affairs would be unlikely to refer enough cases to the Attorney General to meaningfully affect costs.


Local Government


The bills likely would not have a significant fiscal impact on local units of government. It is possible that agreements between a local government and LARA or EGLE for inspections or enforcement could create minor administrative costs for local offices; however, these costs would depend on the specific details of any such contract. Under the bills, these costs would default to the State in the absence of an agreement.
