Buying Land in Morgan County, Indiana
Seat Martinsville, roughly midway between Indianapolis and Bloomington on I-69. Morgan County has a working countywide zoning system through its Advisory Plan Commission, plus a real, currently-unfolding residential growth story tied directly to the interstate's recent completion.
Zoning: the Advisory Plan Commission covers unincorporated land -- four towns opt out
Morgan County zoning runs through the Morgan County Advisory Plan Commission, a nine-member body that reviews and rules on subdivision, development, and rezoning petitions for unincorporated county land. The county's Planning & Zoning Department, headquartered at 180 S Main St in Martinsville, administers the resulting Unified Development Ordinance (UDO), which covers building permits, inspections, floodplain rules, and 911 addressing in addition to zoning itself.
That UDO explicitly stops at the edge of four incorporated jurisdictions: Martinsville, Mooresville, Monrovia, and Morgantown each administer their own separate municipal zoning ordinance rather than falling under the county's. A buyer looking at land near any of these towns -- Martinsville and Mooresville especially, both of which sit closest to the growth described below -- should confirm which zoning authority actually governs the specific parcel before relying on the county's UDO or assuming its terms apply.
A real growth story: I-69's completion has changed Martinsville's trajectory
The final 26-mile stretch of Interstate 69 connecting Indianapolis to Evansville -- the last leg of a project decades in the making -- opened through Morgan County a few years before this research pass, and independent reporting from Indiana Public Media, Inside INdiana Business, and the Morgan County Economic Development Corporation all describe the same basic pattern since: new subdivision activity concentrated around Martinsville, driven by buyers priced out of Indianapolis and Bloomington but still commuting to one or both. As of the most recent reporting available, roughly 450 new home lots were platted and ready for construction, one builder (Arbor Homes) had a 200-plus-home development underway, and year-over-year home sales in the county were reported up around 30% (May 2024 to May 2025).
The county's own economic development office describes this as a deliberate, if cautious, embrace of growth -- targeting modest population gains rather than rapid transformation -- but the volume of new subdivision and rezoning activity moving through the Advisory Plan Commission is real and worth understanding before you buy raw acreage anywhere near Martinsville or along the new interstate corridor. See our dedicated subdivision-development page for Morgan County for what this means for land near the growth corridor specifically.
Septic, GIS, and other departments to know
For a new or repaired septic system on unincorporated Morgan County land, the Morgan County Health Department (also at 180 S Main St, Martinsville) reviews the application and typically completes a site inspection within 2-3 working days once paperwork -- a sketch showing the system, house, other structures, well location, and setback distances from lot lines and waterways, plus a legal description of the property -- is submitted. Septic installers must be registered with the health department under the county's own septic ordinance before pulling a permit or performing work.
Morgan County GIS data and plat copies are available at no charge through the county's online GIS portal, and the County Auditor's and Assessor's offices (both at 180 S Main St, different suites) hold parcel numbers and property records; the Recorder's office holds deeds, easements, and plats. Given the pace of new subdivision activity in and around Martinsville, a buyer evaluating land in that corridor specifically should pull current plat and zoning information directly rather than relying on an older listing description, since nearby parcels may have been platted, rezoned, or annexed more recently than expected.
