Title of proposed rule set:  
Construction Code - Part 9A Mechanical Code  
Comparison of Rule(s) to Federal/State/Association Standard  
1. Compare the proposed rules to parallel federal rules or standards set by a state or national licensing agency or  
accreditation association, if any exist.  
There are no federal rules or standards that regulate construction codes. The proposed rules update the Part 9a.  
Mechanical rules, of the General Rules of the Construction Code as mandated by 1972 PA 230.  
A. Are these rules required by state law or federal mandate?  
State law mandates these rules in MCL 125.1504(5), which states that the director shall add, amend, and rescind rules  
to update the Michigan Mechanical Code not less than once every 3 years to coincide with the national code change  
cycle. There are no federal mandates.  
B. If these rules exceed a federal standard, please identify the federal standard or citation, describe why it is  
necessary that the proposed rules exceed the federal standard or law, and specify the costs and benefits arising out  
of the deviation.  
There are no federal standards that regulate construction codes.  
2. Compare the proposed rules to standards in similarly situated states, based on geographic location, topography,  
natural resources, commonalities, or economic similarities.  
The proposed rules incorporate by reference the 2021 edition of the International Mechanical Code (IMC) with  
Michigan amendments, additions, or deletions published by the International Code Council (ICC). All the surrounding  
Great Lakes state follow the International Mechanical Code and have similar regulations. There are only an estimated  
three states in the whole United States that do not follow the IMC.  
A. If the rules exceed standards in those states, please explain why and specify the costs and benefits arising out of  
the deviation.  
The International Mechanical Code is a nationally recognized model code used throughout the United States as a  
minimum standard for mechanical installations. The Michigan rules do not exceed the standard of any of the other  
Great Lake’s states.  
3. Identify any laws, rules, and other legal requirements that may duplicate, overlap, or conflict with the proposed  
rules.  
MCL 24.245(3)  
RIS-Page 2  
There are no federal, state, or local laws, rules, or other legal requirements that may duplicate, overlap, or conflict  
with the proposed rules.  
A. Explain how the rules have been coordinated, to the extent practicable, with other federal, state, and local laws  
applicable to the same activity or subject matter. This section should include a discussion of the efforts undertaken  
by the agency to avoid or minimize duplication.  
There are no federal, state, or local laws, rules, or other legal requirements that may duplicate, overlap, or conflict  
with the proposed rules.  
4. If MCL 24.232(8) applies and the proposed rules are more stringent than the applicable federally mandated  
standard, provide a statement of specific facts that establish the clear and convincing need to adopt the more  
stringent rules.  
There are no federal rules or standards that regulate construction codes. The proposed rules update the Part 9a  
Mechanical rules, of the General Rules of the Construction Code as mandated by 1972 PA 230.  
5. If MCL 24.232(9) applies and the proposed rules are more stringent than the applicable federal standard,  
provide either the Michigan statute that specifically authorizes the more stringent rules OR a statement of the  
specific facts that establish the clear and convincing need to adopt the more stringent rules.  
There are no federal rules or standards that regulate construction codes. The proposed rules update the Part 9a  
Mechanical rules, of the General Rules of the Construction Code as mandated by 1972 PA 230.

actual practices, to eliminate unnecessary requirements in the code, and to have an easier interpretation and  
clarification of these codes.  
7. Identify the harm resulting from the behavior that the proposed rules are designed to alter and the likelihood  
that the harm will occur in the absence of the rule.  
There is no harm anticipated from behavior related to the proposed rules and there is little likelihood that harm will  
occur in the absence of the proposed rules.  
A. What is the rationale for changing the rules instead of leaving them as currently written?  
The purpose of the proposed rules is to give greater clarity to the code and to continue to protect public health and  
safety.  
8. Describe how the proposed rules protect the health, safety, and welfare of Michigan citizens while promoting a  
regulatory environment in Michigan that is the least burdensome alternative for those required to comply.  
The proposed rules are administrative in nature and are amended and added to bring the administrative application of  
the Michigan Mechanical Code rules in line with actual practices. These rules protect the health, safety, and welfare of  
Michigan citizens by preventing improper installations of mechanical systems. The changes will clarify code  
requirements which will make compliance less burdensome.  
9. Describe any rules in the affected rule set that are obsolete or unnecessary and can be rescinded.

RIS-Page 3  
R 408.30902a, R 408.30908a, R 408.30910a, R 408.30912a, R 408.30927a, R 408.30947a and R 408.30948 are  
being rescinded because the committee decided to go with the International Mechanical Code language.  
Fiscal Impact on the Agency  
Fiscal impact is an increase or decrease in expenditures from the current level of expenditures, i.e. hiring additional staff,  
higher contract costs, programming costs, changes in reimbursements rates, etc. over and above what is currently  
expended for that function. It does not include more intangible costs for benefits, such as opportunity costs, the value of  
time saved or lost, etc., unless those issues result in a measurable impact on expenditures.  
10. Please provide the fiscal impact on the agency (an estimate of the cost of rule imposition or potential savings  
for the agency promulgating the rule).  
There is no additional fiscal impact to the agency beyond the current operational costs.  
11. Describe whether or not an agency appropriation has been made or a funding source provided for any  
expenditures associated with the proposed rules.  
The proposed rules will not result in additional fiscal impact on the agency. Thus, there is no need for an additional  
appropriation or funding source because of the changes to the rules.  
12. Describe how the proposed rules are necessary and suitable to accomplish their purpose, in relationship to the  
burden(s) the rules place on individuals. Burdens may include fiscal or administrative burdens, or duplicative  
acts.  
The proposed rules are administrative in nature and are amended and added to bring the administrative application of  
the Michigan Mechanical Code rules in line with actual practices. These rules protect the health, safety, and welfare  
of Michigan citizens by preventing improper installations of mechanical systems. The changes will clarify code  
requirements which will make compliance less burdensome.

school districts) as a result of the rule. Estimate the cost increases or reductions for other state or local  
governmental units (i.e. cities, counties, school districts) as a result of the rule. Include the cost of equipment,  
supplies, labor, and increased administrative costs in both the initial imposition of the rule and any ongoing  
monitoring.  
There is no anticipated increase or decrease in revenues to other state or local governmental units because of the  
proposed rules. Therefore, other state or local governmental unit should also not accumulate cost increase of  
reductions of such equipment, supplies, labor, and administrative costs during the initial imposition of the rule and  
ongoing monitoring.  
14. Discuss any program, service, duty, or responsibility imposed upon any city, county, town, village, or school  
district by the rules.  
The proposed rules do not require any additional or new responsibilities on behalf of governmental units to be in  
continued compliance with the rules.  
A. Describe any actions that governmental units must take to be in compliance with the rules. This section should  
include items such as record keeping and reporting requirements or changing operational practices.
