You're building in an area where the local jurisdiction has amended the Michigan Building Code to require additional seismic provisions. What is your obligation as a contractor?
Correct Answer
D) Follow the more restrictive of state or local requirements
When local amendments exist, contractors must follow the more restrictive requirements between state and local codes to ensure compliance with all applicable regulations.
Why This Is the Correct Answer
When a local jurisdiction has adopted amendments to the Michigan Building Code that are more stringent than the state code, contractors are legally required to follow the more restrictive of the two sets of requirements. Michigan law permits local governments to adopt amendments that increase (but not decrease) requirements above the state minimum. A contractor must comply with both state and local codes, and when they conflict, the stricter standard governs to ensure maximum public safety.
Why the Other Options Are Wrong
Option A: Choose which code to follow based on cost
Choosing which code to follow based on cost is never acceptable in regulated construction. Code compliance is not optional or cost-dependent. A contractor who ignores stricter local requirements to save money faces license revocation, fines, stop-work orders, and civil liability.
Option B: Follow only the state Michigan Building Code
Following only the state Michigan Building Code is insufficient when a local jurisdiction has lawfully adopted more stringent amendments. Local amendments that exceed state minimums are legally enforceable, and contractors must comply with them in addition to the state code.
Option C: Get homeowner approval for which code to use
Getting homeowner approval for which code to use is not legally valid. Building codes are public safety laws — they cannot be waived or selected by private agreement between a contractor and homeowner. The local building official enforces the applicable code regardless of owner preference.
Memory Technique
Remember 'Strictest Wins.' When multiple codes apply (state + local), always follow the most restrictive one. Think of it as a safety competition — whoever demands more safety wins. 'More restrictive = more protection = required.'
