The office approves lot splits in unincorporated portions of Ashtabula County and reviews and accepts applications for replats and major subdivisions that are brought before the Ashtabula County Planning Commission.  Planning must stamp approved on lot splits (Minor Subdivisions) 5 acres or less in unincorporated  areas of the county before property is transferred.  All splits require review by Township zoning and the sewerage authority (Health Department or Environmental Services) prior to approval.  Consultation with staff is recommended when considering a lot split prior to surveying. 

Townships with zoning submit zoning text and map amendments to Planning and Development for review and submission to the Planning Commission. 

The Department of Planning and Development also assigns address numbers for property within unincorporated areas of all townships, except Ashtabula Township which issues its own address numbers.
  1. Minor Subdivision
  2. Major Subdivision
  3. Address Assignment
