Environmental protection: hazardous products; Michigan statewide microplastics strategy; establish. Amends 1994 PA 451 (MCL 324.101 - 324.90106) by adding pt. 151.

Maddy summarySB 505 requires Michigan's Department of Environment, Great Lakes, and Energy (DEGLE) to create a statewide research and monitoring plan focused on microplastics in the Great Lakes by July 2026. The plan must assess microplastic impacts on drinking water, human/animal health, and the Great Lakes ecosystem, establish baseline data, identify sources, and propose reduction strategies using federal standards (like EPA and NOAA guidelines). It mandates annual updates, public reporting, and requires DEGLE to collaborate with universities and leverage existing federal efforts. The bill directly affects state agencies, researchers, and Great Lakes water quality management, with implementation deadlines set for 2026 and 2028.

Trade: consumer goods and services; personal care products containing plastic microbeads; prohibit manufacture and acceptance for sale. Amends 1994 PA 451 (MCL 324.101 - 324.90106) by adding subpt. 3 to pt. 147.

Maddy summarySB 503 prohibits the manufacture, sale, or distribution of plastic microbeads (intentionally added solid plastic particles ≤5mm) in personal care products (like face scrubs and toothpaste) and cleaning products (including floor cleaners) in Michigan. Starting January 1, 2027, these products cannot contain microbeads unless the concentration is below 1 part per million by weight. The law applies to manufacturers, sellers, and distributors within the state, with enforcement by the Department of Environment, Great Lakes, and Energy. Violations carry civil fines up to $2,000 per day, and the department must report on enforcement annually. The bill does not affect air care products or materials used in non-personal care applications.

Housing: landlord and tenants; reuse of certain tenant screening reports; allow. Amends title & sec. 1 of 1972 PA 348 (MCL 554.601) & adds secs. 1e, 1f, 1g & 1h.

Maddy summarySB 372 allows landlords to reuse tenant screening reports prepared by prospective tenants within the previous 45 days, reducing costs for renters. Landlords who accept these reusable reports cannot charge a rental application fee, while those who decline may charge up to $25 only if they first disclose all screening criteria in writing. The bill requires landlords advertising rentals to state whether they accept reusable screening reports. It directly affects prospective tenants (who pay less for applications) and landlords (who must adjust their screening processes and fee structures). The bill amends Michigan's Landlord and Tenant Act to streamline screening and limit fees.

Civil procedure: evictions; court records of summary proceedings; provide for the sealing and expungement of. Amends 1961 PA 236 (MCL 600.101 - 600.9947) by adding sec. 5755.

Maddy summarySB 374 changes Michigan's eviction court record rules to help tenants by making it easier to seal or remove their records. It requires courts to seal eviction records until a judgment for possession is entered and allows sealing after judgment if the tenant vacated before the case, received emergency rental assistance, or owed less than $900 in rent. The bill automatically removes (expunges) records three years after a judgment becomes final and restricts access to sealed records - only allowing limited release for scholarly, educational, or legal purposes with court approval. This directly affects tenants in eviction cases and landlords who might otherwise use sealed records to deny housing.

Housing: landlord and tenants; limitations on fees charged to tenants; provide for. Amends secs. 2 & 3 of 1978 PA 454 (MCL 554.632 & 554.633).

Maddy summarySB 375 amends Michigan's Truth in Renting Act to clarify that "rent" includes essential services like heat, water, electricity, and pest control provided by landlords. It prohibits landlords from charging unreasonable fees, such as late fees exceeding $30 or 3% of rent, fees for non-renewal notices beyond one month, or fees for third-party services. The bill also requires rental agreements to include specific terms like tenant/landlord names, property description, rent amount, and payment schedule. These changes directly affect Michigan tenants and landlords by increasing transparency and preventing unfair financial burdens.

Health facilities: other; hyperbaric oxygen inspection fund; create. Amends 1978 PA 368 (MCL 333.1101 - 333.25211) by adding sec. 21224 to pt. 212. TIE BAR WITH: SB 0803'26, SB 0804'26, SB 0805'26

Maddy summarySB 806 creates a dedicated "hyperbaric oxygen therapy inspection fund" in the state treasury, funded by licensing fees paid by freestanding hyperbaric oxygen therapy facilities. The fund is managed by the state treasurer and administered by the state health department, with all money used solely for inspecting these facilities. This bill directly affects hyperbaric oxygen therapy providers and the state's inspection process for their facilities. The fund ensures consistent, dedicated funding for inspections, replacing general appropriations for this specific purpose.

Health facilities: other; licensure of freestanding hyperbaric oxygen therapy facilities; provide for. Amends secs. 20104, 20106, 20155, 20161, 20162 & 20164 of 1978 PA 368 (MCL 333.20104 et seq.). TIE BAR WITH: SB 0804'26, SB 0805'26, SB 0806'26

Maddy summarySB 803 creates a new licensure requirement for freestanding facilities that provide hyperbaric oxygen therapy (HBOT), a medical treatment using pressurized oxygen. It directly affects businesses operating standalone HBOT centers and patients receiving this therapy by establishing specific safety and operational standards. The bill amends Michigan's Public Health Code to add licensing rules for these facilities, ensuring they meet state health and safety criteria. This change applies to facilities not located within hospitals, requiring them to obtain state licensure before operation.

Maddy summarySB 804 adds new licensing requirements for freestanding hyperbaric oxygen therapy facilities in Michigan, directly affecting these specialized treatment centers. The bill requires facilities to appoint a medical director and safety coordinator, comply with national fire safety standards (NFPA 99), and ensure staff meet specific licensing qualifications. It defines key terms like "accreditation organization" and "qualified health professional" to establish clear operational standards. The legislation is contingent on three related bills (SB 803, 805, 806) also being enacted.

Criminal procedure: sentencing guidelines; sentencing guideline for facility that receives or maintains an adult who requires residential psychiatric care when the facility's license has been revoked or suspended or it has refused to renew its license; enact. Amends sec. 13j, ch. XVII of 1927 PA 175 (MCL 777.13j). TIE BAR WITH: SB 0799'26

Maddy summarySB 800 amends Michigan's sentencing guidelines to add specific provisions for cases involving adults requiring residential psychiatric care who are placed in facilities with revoked, suspended, or unrenewed licenses. It directly affects courts and correctional facilities by establishing a new sentencing guideline (under MCL 777.13j) for such placements. The bill creates a standardized sentencing consideration when a facility loses its license but continues to house patients needing psychiatric care. This change ensures courts account for facility licensing status when determining sentences for these cases. (Note: The bill text provided does not include specific policy details beyond the title and amendment reference.)
