Do I need a permit for addition or structural alteration in Allendale Charter Township?
Yes. In Michigan, addition or structural alteration generally requires a permit, and Allendale Charter Township is no exception.
State law requires scaled plans and a site plan with every building permit application (MCL 125.1510(1)); LARA notes an architect's or engineer's seal is not required for one- and two-family dwellings under 3,500 square feet of calculated floor area. Michigan's amendment to R109.1.4 requires the framing inspection only after the plumbing, mechanical, and electrical rough inspections are approved. When an addition or alteration needs a permit, the home must be brought up to current smoke alarm locations (R314.2.2 as amended), and carbon monoxide alarms are required where there is an attached garage or fuel-fired appliance (R315.3 as amended). The 2015 Michigan Residential Code remains in effect while a court order holds the 2021 update; confirm the edition with the enforcing agency.
