In Troy, Michigan, subdividing property requires coordination with the City Planning Division, compliance with the City zoning and floodplain rules, and permits from Building and Engineering. This guide explains typical steps, what floodplain rules mean for lot configuration, where to find official forms, and how enforcement and appeals usually work so you can plan correctly for development in Troy.

Overview of the process

Start by confirming zoning and floodplain status for the parcel with the City of Troy Planning Division and by reviewing the City of Troy Code of Ordinances for floodplain and subdivision rules. Visit the City Planning page for subdivision filing instructions and pre-application guidance City of Troy Planning Division[1] and consult the municipal code for regulatory text on zoning and floodplain regulations City of Troy Code of Ordinances[2].

Get a zone and floodplain map early to avoid redesigns.

Step-by-step checklist

  • Confirm current parcel zoning, lot size minimums, and permitted uses with Planning.
  • Order or check floodplain mapping for the parcel; if any portion lies in a regulated floodplain, additional restrictions or elevations will apply.
  • Prepare a preliminary subdivision plat or land division sketch showing lots, access, utilities, and drainage; submit for pre-application review.
  • Coordinate required stormwater, grading, and utility plans with the Engineering Division and include any floodproofing or elevation measures.
  • Submit formal plat or land division application with required fees, application forms, and supporting documents; attend any required public hearings or Planning Commission meetings.
  • Pay review, inspection, and recording fees as billed; record approved plats with the County Register of Deeds as instructed.
Early meetings with Planning reduce the risk of noncompliance and rework.
