Do you need a building permit in Henry County, Indiana?
Unincorporated Henry County requires an owner or agent to obtain a building permit before constructing, enlarging, altering or moving a structure1. The statewide 2020 Indiana Residential Code applies to covered one- and two-family dwellings and townhouses in Henry County; other covered construction falls under Indiana’s building-code rules910. Henry County requires plot plans for additions, new structures, roofline alterations and other exterior remodeling11. Indiana’s agricultural exemption concerns the state Class 1 design-release requirement for qualifying farm-use buildings; we could not confirm a Henry County exemption from local building or zoning requirements, so ask Planning & Zoning before relying on it12.
Who issues building permits in Henry County, and how do you reach the office?
Henry County’s Planning & Zoning Department handles county building and zoning applications at 1201 Race Street, New Castle, IN 47362; call (765) 529-740811. Bring a plot plan for a new structure, addition, roofline alteration or other exterior remodeling11. A complete and accurate application can take up to 10 days from acceptance to permit issuance11. The building application packet directs applicants to Henry County Health Department’s Environmental Health Division for septic installation and Henry County Highway Department for a driveway permit on a county road11. Ask Planning & Zoning which building and zoning authority serves the parcel before applying, especially inside municipal limits.
Does Henry County have zoning?
Henry County has a Development Code administered by its Planning Commission, with zoning districts and district-specific minimum lot sizes2. The county guidance here concerns unincorporated land; we could not confirm the complete boundary between county and municipal zoning authority. Ask Henry County Planning & Zoning which jurisdiction and district govern the parcel, then request the applicable setbacks, lot size and permitted uses11. We could not confirm Henry County’s rules for RV residence, tiny-home occupancy, accessory dwellings, minimum dwelling size, building height or lot coverage. Describe the proposed dwelling and use to Planning & Zoning before buying11.
How do septic permits work in Henry County?
Henry County requires septic permits through the Henry County Health Department, which also inspects and approves onsite sewage systems133. Submit a soil test and application; the department prepares the Technical Specification Data Sheet within 48 hours after receiving both14. A contractor must submit a system plan before the onsite evaluation; a compliant plan receives a septic permit, and the department conducts the final inspection1315. Published septic fees are $225 for new construction, $200 for replacement or expansion, $75 for component repair or replacement, $50 to connect to an existing system and $200 for commercial projects; conflicting renewal fees require confirmation with the Health Department16. Inside Shirley, where public sewer is unavailable, private sewage construction also requires notification through the Superintendent and Town Council permission; county health requirements still apply17. Henry County’s soil survey rates 0% of mapped land as free of severe limitations for conventional drain fields, making the parcel-specific soil test essential5.
Can you live in an RV or tiny home on your land in Henry County?
We could not confirm a Henry County rule that generally allows long-term RV residence or tiny-home occupancy on private land. Henry County does have zoning districts under its Development Code, so the Planning & Zoning Department should confirm the permitted use and dimensional rules for the specific parcel2. Indiana's campground rule addresses RV occupancy at regulated campground campsites, not residential occupancy on an individually deeded lot, so it does not answer whether you may live in an RV on your own Henry County land18. Before buying for either use, describe the structure, foundation, utilities, duration of occupancy and parcel location to Planning & Zoning at (765) 529-740811. Ask the Health Department separately how the proposed dwelling will satisfy sewage requirements3.
Building on land in Henry County: the steps, in order
- Ask Henry County Planning & Zoning to confirm the parcel's governing jurisdiction, zoning district, proposed use, setbacks and lot standards2.
- Order the required soil test and submit it with the septic application to Henry County Health Department13.
- Have the septic contractor submit a system plan, complete the onsite evaluation, obtain the septic permit and arrange the final inspection1315.
- Obtain a Henry County Highway Department permit for a new or modified driveway on a county road; an approach on a state highway instead requires permission through INDOT's permit system1920.
- Submit the county building and zoning application with a plot plan for new construction or exterior remodeling; a complete, accurate application may take up to 10 days for permit issuance11.
- If the site is in a floodway, determine whether Indiana DNR approval is required before construction21.
What to check before you buy land in Henry County
Make septic feasibility a purchase contingency: 0% of Henry County's mapped soils are rated free of severe limitations for a conventional drain field, but only a parcel-specific soil test can determine a workable design5. Identify whether access is from a county road or state highway because separate driveway authorities apply1920. Check flood maps as well: Indiana DNR oversees most floodway development, while flood-fringe work has no state permit but may still require local approval2122. Henry County's effective property-tax rate is about 0.7%, with a median yearly bill near $1,05078. Typical home insurance is about $1,529 per year23. The land is largely gentle: 98.9% is at a slope of 15% or less, while 12.4% is wooded2425. The nearest city of 100,000 or more is about 31 miles from the county center26.
Watch-outs
- We could not confirm an owner-builder exemption from Henry County’s building permit requirement; ask Planning & Zoning what permits and contractor requirements apply to your project4.
- The soil survey rates 0% of Henry County land as free of severe limitations for a conventional septic drain field, so require a parcel-specific soil test before assuming a lot can support the proposed system5.
- Indiana's campground and RV-park rules govern licensed campgrounds, not year-round RV living on your own deeded lot — confirm your specific rule with Henry County Planning & Zoning instead18.
