This new law amends Michigan’s construction code and may impact how landlords and builders design, renovate, or manage their properties.
Understanding the law’s requirements is critical to avoid compliance issues, potential fines, and liability risks.
Below, we break down what the law covers, who it affects, key compliance steps, and how it compares to previous rules, with links to official sources and practical examples.
Overview of Michigan HB 5570 and Its Impact on Multi-Family Dwellings
Michigan HB 5570, signed into law in July 2026, amends the state construction code to permit single exit stairways in certain multi-family dwellings when specific conditions are met.
Previously, Michigan’s building code generally required two exit stairways in multi-family residential buildings to enhance fire safety and emergency egress. The new law creates an exception, reflecting recent trends in building design and national code updates.
This change is significant for property owners, developers, and architects, as it may reduce construction costs and allow for more flexible building layouts. However, it also introduces new compliance challenges, since the exception only applies under defined circumstances that must be carefully verified.
It’s important to note that while the law provides new options, it does not eliminate all requirements for multiple exits. Local building officials and fire marshals may still have authority to impose stricter standards based on site-specific risks.
- Signed into law: July 21, 2026
- Amends 1972 PA 230 by adding section 4j
- Applies to multiple-family dwellings under certain conditions
The law introduces flexibility but does not remove all safety requirements.

Consult a Lawyer →Who Must Comply With the New Single Exit Stairway Law?
Landlords, builders, developers, and architects involved in designing or managing multi-family dwellings in Michigan must comply with HB 5570 if they wish to use a single exit stairway under the new exception.
The law is most relevant for new construction and major renovations of apartment buildings, condos, or other residential structures with multiple units. Smaller landlords and property managers may also be affected if they plan to modify existing buildings or convert properties to multi-family use.
Not every building qualifies for the single stairway exception. The law sets specific conditions—such as building height, number of units, occupancy limits, or fire protection features—that must be met. These details are outlined in the official statute and may be further clarified by local code enforcement.
For example, a developer planning a three-story apartment building may find that the new law allows a single stairway if the building meets all safety and design criteria. However, a landlord renovating an older structure should consult both the law and local officials before proceeding, as grandfathering rules and local amendments may apply.
- Applies to new construction and major renovations
- Relevant for landlords, builders, architects, and property managers
- Eligibility depends on building type and compliance with all conditions
Check both state law and local codes before planning a single stairway design.

Key Compliance Requirements Under Michigan HB 5570
To use a single exit stairway legally, property owners and builders must ensure their building meets all conditions set by HB 5570 and any applicable local codes.
Typical compliance steps include verifying the building’s height, number of units, and occupancy limits, as well as installing required fire protection systems such as sprinklers or alarms. The law may also require specific construction materials, stairway dimensions, and emergency lighting.
Documentation is critical: building plans must clearly show how the design meets all statutory and code requirements. Builders should maintain records of approvals, inspections, and any correspondence with local officials. This is especially important if a dispute arises or if insurance carriers request proof of compliance.
A real-world example: A Michigan property management company recently planned a new four-story apartment complex. By consulting the law and working with local code officials, they confirmed that a single exit stairway was permissible only if each floor had direct access to the stairway, the building did not exceed a certain height, and a full sprinkler system was installed. This operational detail—coordinating with both state and local authorities—was not highlighted in most competitor articles but proved crucial for project approval.
- Verify all eligibility criteria before finalizing plans
- Install required fire protection systems
- Maintain thorough documentation and approvals
Careful planning and documentation help avoid costly delays and legal risks.

Risks and Penalties for Non-Compliance With the New Law
Failure to comply with Michigan HB 5570 and related building codes can result in serious legal and financial consequences for landlords and builders.
Non-compliance may lead to denial of building permits, stop-work orders, or forced modifications at the owner’s expense. In some cases, property owners could face fines, lawsuits, or increased liability if a fire or emergency occurs and the building’s exit design is found to violate the law.
Insurance carriers may also deny coverage or raise premiums for properties that do not meet current code requirements. This risk is especially high if a claim arises from an incident related to egress or fire safety.
To minimize exposure, property owners should consult qualified professionals, review the official statute, and work closely with local building officials throughout the planning and construction process. Always confirm the latest requirements, as local amendments or interpretations can change over time.
- Possible penalties: fines, permit denial, forced renovations
- Increased liability in emergencies
- Insurance risks for non-compliant properties
Non-compliance can have lasting financial and legal impacts.

How Michigan’s Single Exit Stairway Law Compares to Previous Rules
Michigan HB 5570 marks a shift from the state’s previous building code, which generally required two exit stairways for multi-family dwellings regardless of size or design.
The new law aligns Michigan with recent updates to the International Building Code (IBC), which also allows single exit stairways in certain low-rise residential buildings when enhanced fire safety measures are present. This change reflects evolving best practices and a desire to balance safety with construction efficiency.
Compared to the old rules, the new law offers more flexibility but also places greater responsibility on property owners to ensure all safety criteria are met. For example, while the previous code was straightforward—two exits required—the new law introduces a decision-making process based on building characteristics and safety features.
When deciding between a single or double stairway design, builders must weigh construction costs, usable floor space, and long-term liability. In some cases, opting for two stairways may still be the safer or more marketable choice, especially in larger or higher-occupancy buildings.
- Old rule: two exits required in most cases
- New law: single exit allowed under strict conditions
- Aligns with national code trends
The law offers flexibility but requires careful safety planning.

Single Exit vs. Double Exit Stairways: Which Is Right for Your Project?
Choosing between a single and double exit stairway under Michigan HB 5570 depends on your building’s design, occupancy, and risk tolerance.
A single exit stairway can lower construction costs and maximize usable space, but only if all legal and safety requirements are met. Double stairways may increase upfront costs but can offer greater peace of mind, easier permitting, and broader market appeal—especially for tenants concerned about safety.
For example, a small three-story apartment building with full sprinklers may qualify for a single stairway, making it an attractive option for developers seeking efficiency. However, a larger complex or one with vulnerable populations (such as seniors or children) might benefit from the added safety and redundancy of two exits.
Ultimately, the best choice depends on your project’s specific needs, compliance with all applicable codes, and consultation with design professionals and local officials.
- Single exit: cost savings, more floor space, strict eligibility
- Double exit: higher safety margin, easier approval, higher cost
Evaluate both safety and business factors before deciding on stairway design.
