Building permits, zoning and septic rules in Delaware County, Indiana

Unincorporated Delaware County, Indiana requires a building permit, and the county's Building Commissioner's Office issues permits for projects in the unincorporated county^1,2. Indiana currently applies the 2020 Indiana Residential Code to covered one- and two-family dwellings and the 2014 Indiana Building Code to covered buildings⁹. Permitted Delaware County projects require inspections, with additional inspections possible depending on the work³. All construction phases must be complete for the final inspection, which must occur before the owner occupies the structure and receives a certificate of occupancy³. We could not confirm an owner-builder exemption, so ask the Building Commissioner's Office before assuming you can pull the permit without a licensed contractor⁵.

Delaware County's Building Commissioner's Office is a division of the Delaware-Muncie Metropolitan Plan Commission and also serves as the county's Zoning Administrator². Reach the office at (765) 747-7799, at 100 W Main St, Muncie, Indiana². General, electrical, plumbing and HVAC contractors working in unincorporated Delaware County must register annually and maintain current insurance coverage². After permit issuance, schedule required building inspections 24 to 48 hours ahead; missing an appropriate inspection can result in fines³. A covered commercial project must also obtain an Indiana design release before local building permits are issued^2,6.

Delaware County has zoning in the unincorporated county, administered by the same Building Commissioner's Office that also issues building permits, acting as the county's Zoning Administrator². A landowner who wants to subdivide land outside a municipality must record a correct, surveyor-certified plat with the county recorder, and once Delaware County's subdivision-control ordinance applies, the plan commission has exclusive control over approving that plat¹⁰. Because the specific district rules, setbacks and allowed dwelling types come from the county's own zoning ordinance and map rather than from a statewide rule, confirm your parcel's zoning district with the Building Commissioner's Office at (765) 747-7799 before you buy².

Delaware County septic permits go through the Delaware County Health Department's Environmental Health Division under Indiana's statewide onsite-sewage rules^4,11. Start with soil testing by an IRSS-certified soil scientist, locate the fresh-water well, and submit a detailed system design to the Health Department¹². The proposed septic system must sit more than 50 feet from a private well and more than 200 feet from a public water-supply well; plan review may take up to 45 days¹². A new-system permit costs $180 and a repair or replacement application costs $70⁴. Give 48 hours' notice for the county's final inspection and leave system components uncovered; approval for use follows satisfactory inspection¹². If sanitary sewer is available within a reasonable distance, an onsite system is prohibited and the property must connect to sewer¹³. Only about 0.4% of county soils avoid a severe USDA limitation for a conventional drain field, so make soil approval a purchase contingency⁷.

Indiana's statewide campground rule only governs licensed campgrounds with ten or more tents, RVs or vacation mobile homes, and caps occupancy at one RV per designated campsite there; it does not authorize or address long-term residential RV living on an individually deeded rural lot¹⁴. Whether you can live in an RV or place a tiny home on your Delaware County land is a zoning question for the Building Commissioner's Office, since Delaware County's own zoning ordinance, not a statewide rule, decides what a specific parcel allows². A temporary campground under Indiana's rules is capped at ten consecutive days per event and thirty days a year, which is a short-term event rule, not a residential-occupancy rule, so it likewise does not answer whether you can live on your land in an RV¹⁴. Call the Building Commissioner's Office at (765) 747-7799 before you buy to ask specifically about RV and tiny-home occupancy for your parcel's zoning district².

1. Confirm the parcel's zoning district with the Building Commissioner's Office at (765) 747-7799².
2. Ask whether sanitary sewer is available; Delaware County cannot approve an onsite sewage system when sewer is available within a reasonable distance¹³.
3. For a septic site, hire an IRSS-certified soil scientist, locate the well and submit the system design to the Health Department¹².
4. Apply for the county building permit through the Building Commissioner's Office^1,2.
5. Obtain any required state design release, state-highway driveway permit or floodway approval^6,15,16.
6. Schedule building inspections 24 to 48 hours ahead and the septic final inspection 48 hours ahead^3,12.
7. Keep septic components uncovered for inspection, finish every construction phase, and obtain septic approval for use and the building certificate of occupancy before moving in^3,12.
