Do you need a building permit in Hancock County, Indiana?
Yes. Hancock County requires a building permit for a home in the unincorporated county, issued by the Hancock County Building Department under the Indiana Residential Code1. The Building Department also performs all required inspections for construction under county jurisdiction, although the county's public page does not list every inspection stage or exemption2. Indiana adopts and amends the model codes used statewide, including the Indiana Residential Code9. A new home also needs an Improvement Location Permit from the Planning Department for zoning review3. If the parcel uses septic, the Hancock County Health Department's septic permit must come before the building permit45.
Who is the Hancock County building department, and how do you reach them?
The Hancock County Building Department issues building, electrical, pool and sign permits and performs required inspections for unincorporated Hancock County, Spring Lake and Shirley10. Reach the Building Department at 111 American Legion Place, Suite 146, Hancock County Annex, Greenfield, Indiana, or by phone at 317-477-1133, Monday through Friday from 8 a.m. to 4 p.m.10. The Planning Department shares that address and handles Improvement Location Permits, zoning enforcement, plats and new addresses; its phone number is 317-477-113411. Start with Planning when a project involves a new building location, a lot split or a zoning question, then use Building for the construction permit and inspections122.
Does Hancock County have zoning?
Yes. The Hancock County Planning Department administers zoning and Improvement Location Permits in unincorporated Hancock County; incorporated municipalities may apply separate local rules3. Setbacks depend on the zoning district and street: the ordinance has district-specific front, side and rear yards, special front-yard treatment for specified county roads and local subdivision streets, and a separate cul-de-sac rule6. Building height also varies by district and structure type; outside the listed A-1, I-1 and I-2 exceptions, principal structures are capped at 45 feet and accessory buildings at 16 feet7. Agricultural accessory structures may qualify for a different height treatment only when the owner files the required affidavit certifying exclusive agricultural use8. Hancock County also regulates subdivisions through its subdivision ordinance and Planning Commission process, so ask Planning before dividing or replatting land12.
How do septic permits work in Hancock County?
The Hancock County Health Department administers residential septic permits and inspections, while Indiana's statewide on-site sewage rules also apply413. The county requires the septic permit before it will issue the building permit5. Apply through Environmental Health at 111 American Legion Place, Suite 150, Hancock County Annex, Greenfield, Indiana, or call 317-477-1125; septic permits are issued from 8 a.m. to 10 a.m. or by appointment5. County soils deserve early attention because 0% of surveyed soil is rated free of severe limitations for a conventional septic drain field14. Indiana permits temporary holding tanks only in limited circumstances and does not allow drywells or cesspools as residential on-site sewage treatment15.
Can you live in an RV or tiny home on your land in Hancock County?
We could not confirm a Hancock County rule that authorizes year-round RV living on an individually deeded lot, so ask the Planning Department about the parcel and proposed duration before relying on an RV as housing11. Indiana's campground rules govern regulated campgrounds, not residential occupancy on an individually deeded lot, and therefore do not answer that question16. We also could not confirm a distinct county tiny-home occupancy rule; a tiny home still needs review under the parcel's zoning, setbacks and applicable building-permit process361. Do not assume an agricultural label removes those reviews: the documented county agricultural exception concerns the height of qualifying accessory structures and requires an affidavit of exclusive agricultural use8.
Building a home in Hancock County: the steps, in order
- Ask the Planning Department to confirm the parcel's zoning district, setbacks, height limits and whether a lot split or replat needs subdivision review6712.
- If the site will use septic, obtain the Hancock County Health Department permit before applying for the building permit45.
- Obtain the Planning Department's Improvement Location Permit for the proposed building location3.
- Apply to the Hancock County Building Department for the building permit under the Indiana Residential Code19.
- Get the road authority's approval for the driveway; INDOT uses its Electronic Permit System for connections to a state highway17.
- Arrange the Building Department's required inspections as work proceeds2.
- Before occupancy, ask the Building Department what final approval is required because we could not confirm the county's certificate-of-occupancy rule10.
What to check before you buy land in Hancock County
Water: Indiana says some local health departments require a permit before a residential well is drilled or its pump installed, but we could not confirm whether Hancock County does, so ask Environmental Health before drilling185. Soils: 0% of Hancock County's surveyed soil is rated free of severe limitations for a conventional septic drain field, making an early site evaluation especially important14. Flood: Indiana DNR permits most development in a floodway, while flood-fringe work has no state permit but can still face local rules; the County Surveyor participates in technical review of floodplain and drainage issues192021. Access: INDOT approval is required for a driveway connection to a state highway17. Lot layout: verify district-specific setbacks and height rules before closing, and ask Planning about subdivision review if the parcel will be divided6712.
Watch-outs
- We could not confirm that Hancock County permits an RV as a year-round dwelling on an individually deeded lot, so confirm the parcel and proposed use with the Planning Department11.
- Building without a permit doubles your permit fee under Hancock County's fee schedule, so pull your Improvement Location Permit and building permit before you start work22.
- We could not confirm an owner-builder exemption from Hancock County's building requirements; call the Building Department before planning to build without a licensed contractor2310.
