Retaining Wall Permit Requirements in Grandville, MI
The City of Grandville (Kent County) contracts all building, electrical, mechanical, plumbing, and sign permits and inspections to Professional Code Inspections of Michigan (PCI), operating from its Jenison office, per the official cityofgrandville.com Community Development page. PCI is the enforcing agency, so the AHJ is the city (city_dept model) administered by a third party, not the State of Michigan. Permit applications are submitted through the PCI BS&A Online portal (Jenison uid 3129) or downloadable PDF forms. Residential work follows the 2015 Michigan Residential Code (2015 IRC base); the 2021 IRC update was filed effective Aug 29 2025 but remains enjoined by a Michigan Court of Claims order as of June 2026.
