Hamilton County Regional Planning Commission (Subdivision Administrator)

Minor Subdivision (lot split) — final submission

This record reaches a business only when land is being divided or platted rather than simply built on — splitting a parcel to sell off a pad site, carving a lot for a second building, or platting for a new commercial development. The county's development-process page states that 'All subdivision functions within the unincorporated townships in Hamilton County are coordinated through the Hamilton County Subdivision Administrator in the Planning and Development Department', working to the Regional Planning Commission's Rules and Regulations for Plats and Subdivision of Land within the Unincorporated Territory of Hamilton County. Appendix C-1 of those regulations, effective 1 January 2026, prices a minor subdivision (a lot split) final submission at $255.00 per lot plus the 5 per cent technology fee that has applied to these schedules since 17 January 2017. A larger project is priced quite differently: a major subdivision of more than five lots pays a $2,178 base fee for 6 to 20 lots plus $109.00 for each lot above 20, capped at $16,023.00, and the improvement plan and record plat are each $1,283.00 unless already paid at the preliminary plan stage. A subdivision variance is $450.00. Because the platting step produces the lots that everything else attaches to, it runs ahead of the zoning certificate and the building permit, and the stormwater submittal explicitly covers inspections for one year after the record plat is recorded.
