Do you need a building permit in Hancock County, Indiana?

Yes. Hancock County requires a building permit for a home in the unincorporated county, and the Building Department performs the required inspections for work it administers¹⁷. One- and two-family dwellings are governed by Indiana's statewide residential code, which adopts the 2018 International Residential Code with Indiana amendments¹⁰. A new home also needs an Improvement Location Permit for zoning review in the Planning Department's jurisdiction¹¹. If the parcel uses septic, obtain the Hancock County Health Department septic permit before the building permit⁵.

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 Shirley¹². 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.¹². The Planning Department shares that address and handles Improvement Location Permits, zoning enforcement, plats and new addresses; its phone number is 317-477-1134¹³. Start with Planning for a building location, lot split or zoning question, then use Building for the construction permit and inspections¹⁴⁷.

Does Hancock County have zoning?

Hancock County zoning applies to unincorporated land; municipalities outside the County Area Plan Commission may have separate rules¹⁵. The official zoning map identifies Agricultural, Residential, Commercial, Institutional, Industrial and Planned Unit Development districts¹⁶. Minimum living area ranges from 720 square feet in RMH to 1,200 square feet in A, RR, R1.0 and R2.5⁸. A and RR lots require 1.5 acres with septic or 1 acre with sewer; parcels without approved wastewater treatment or sanitary sewer service must follow A District lot and yard requirements, even where another district lists smaller lots⁹. A and RR have 50-foot front and 15-foot side and rear setbacks; height and coverage limits also vary by district¹⁷¹⁸¹⁹. An accessory dwelling is limited to 850 square feet, must be attached to the primary structure or above a detached garage or workshop, and requires a special exception in several districts²⁰. Subdivision rules apply in every zoning district; ask Planning which plat review or exception procedure applies before splitting or replatting land¹⁶²¹.

How do septic permits work in Hancock County?

The Hancock County Health Department issues septic permits, and the permit must be obtained before the building permit⁵. Apply through Environmental Health at 111 American Legion Place, Suite 150, Hancock County Annex, Greenfield, Indiana, or call 317-477-1125; permits are issued from 8 a.m. to 10 a.m. or by appointment²². County soils deserve early attention because 0% of surveyed soil is rated free of severe limitations for a conventional septic drain field²³. Indiana does not allow drywells or cesspools as on-site sewage treatment, but that restriction does not settle every alternative system²⁴. In a cluster subdivision with lots smaller than 43,000 square feet, connection to public or semipublic water and sanitary sewer is mandatory; that is not a countywide connection rule²⁵.

Can you live in an RV or tiny home on your land in Hancock County?

We could not confirm a Hancock County rule authorizing year-round RV living on an individually deeded lot; ask the Planning Department about the parcel and proposed duration¹³. Indiana campground rules do not answer residential RV occupancy on an individually deeded lot²⁶. We could not confirm a distinct tiny-home occupancy rule; a proposed tiny home still faces building permits and district-specific dwelling, lot and setback standards¹⁸⁹²⁷. For agricultural accessory structures, Hancock County allows a height exception when the landowner submits a signed affidavit to the Plan Director certifying exclusively agricultural use; that exception does not establish a general building-permit or zoning waiver²⁸.

Building a home in Hancock County: the steps, in order

1. Ask the Planning Department to confirm the mapped zoning district, wastewater-dependent lot and yard standards, minimum living area, and whether a division or replat needs review¹⁶⁹⁸²¹.
2. If the site will use septic, obtain the Health Department permit before applying for the building permit⁵.
3. Obtain the Planning Department's Improvement Location Permit for the proposed building location¹¹.
4. Apply to the Building Department for the building permit under Indiana's statewide residential code¹¹⁰.
5. Ask the Highway Department about county-road driveway requirements; a state-highway connection requires INDOT approval²⁹³⁰.
6. Arrange the Building Department's required inspections as work proceeds⁷.
7. Ask the Building Department what final occupancy approval applies because we could not confirm the county rule¹².

What to check before you buy land in Hancock County

Water: we could not confirm a Hancock County well-permit rule, so ask Environmental Health before drilling²². A cluster subdivision with lots under 43,000 square feet must connect to public or semipublic water and sewer, but we could not confirm a countywide connection mandate²⁵. Soils: 0% of surveyed soil is rated free of severe limitations for a conventional septic drain field, making early site evaluation important²³. Flood: Indiana DNR permits most floodway development, while flood-fringe work has no state permit but may face local rules; the County Surveyor participates in floodplain and drainage review³¹³²³³. Access: INDOT approval is required for a state-highway driveway³⁰.

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 Department¹³.
• 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 work³⁴.
• We could not confirm an owner-builder exemption from Hancock County building-permit requirements; ask the Building Department before assuming that building your own home waives the permit³⁵¹².
