Do you need a building permit in Warrick County, Indiana?
Unincorporated Warrick County requires building permits for residential construction; the Building Department reviews plans and conducts inspections for compliance with state and local laws1. Residential applications must include blueprints or computer-generated house plans, with drawings no larger than 11 by 17 inches for scanning1213. The published single-family building-permit fee is $0.08 per square foot with a $200 minimum; additional inspections outside the normal sequence cost $25 each14. Applicable one- and two-family construction follows the 2020 Indiana Residential Code, based on the 2018 International Residential Code1516. Buildings used only for agriculture on the land where that activity occurs, without retail trade, avoid Indiana's state Class 1 design-release classification; confirm local building-permit and zoning requirements separately with the Building Department and Area Plan Commission171318.
Who issues building permits in Warrick County, and how do you reach them?
The Warrick County Building Department, at 107 West Locust St, Suite 208 in Boonville, reviews plans, issues building permits and conducts construction inspections1319. Call 812-897-6188 or email buildingcomm@warrickcounty.gov13. Start with the Area Plan Commission at 812-897-6190 to identify the zoning and Improvement Location Permit paperwork for the parcel, then confirm the required building applications with the Building Department1218. Warrick County publishes an Area Plan fee schedule as well as residential building-permit fees, including a $100 mobile-home permit fee2014.
Does Warrick County have zoning?
The Warrick County Area Plan Commission administers zoning in unincorporated Warrick County and identifies Elberfeld, Lynnville and Tennyson within its planning jurisdiction2. Boonville has its own Unified Development Ordinance, and Newburgh and Chandler have their own zoning ordinances212223. Septic permits remain with the Warrick County Health Department24. Ask the Area Plan Commission for the current district table for a county-zoned parcel: the ordinance history records a 0.5-acre minimum in CON and A, setback standards in R-2B, and a 45-foot maximum height in R-225262728. Covered plats and replats need commission approval before recording or selling a proposed subdivision parcel8.
How do septic permits work in Warrick County?
The Warrick County Health Department's Sanitarian/EHS office issues septic permits, reviews septic plans, performs site evaluations and oversees system improvements and repairs24. Where sanitary sewer is available within a reasonable distance, an on-site sewage system is prohibited and sewer connection is required4. In covered subdivisions without public sewer, private septic systems require Health Department approval and zoning permission29. Only 4.1% of Warrick County soils rate free of severe limits for a conventional drain field, so obtain a site evaluation before assuming a standard system will work724. Indiana requires a compliant septic tank and soil-absorption system where a dwelling cannot connect to sewer; drywells and cesspools are not allowed30. Inside Lynnville, private sewage installations also require final inspection by the town Superintendent before underground portions are covered31.
Can you live in an RV or tiny home on your land in Warrick County?
We could not confirm a Warrick County rule allowing long-term RV living or tiny-home occupancy on an individually deeded parcel; ask the Area Plan Commission before planning residential occupancy18. Ask the Area Plan Commission about the parcel's zoning district, the proposed dwelling, district-specific setbacks and any temporary-use approval before buying52718. Indiana's campground rule does not answer the private-lot question because it governs regulated campgrounds rather than individually deeded lots32. In covered subdivisions without public sewer, an approved private septic system is allowed, but that sanitation rule does not by itself authorize an RV or tiny home as a residence29.
What are the steps to building a home in Warrick County?
- Confirm which jurisdiction controls the parcel: the county ordinance excludes Boonville, Newburgh and Chandler3.
- Ask the Warrick County Area Plan Commission for the zoning district, use rules, setbacks and Improvement Location Permit paperwork; if land will be divided, ask about plat approval before recording or selling a parcel258.
- If public water or sewer is unavailable in a subdivision, take the proposed private well and septic plan to the Health Department for approval3334.
- Contact the Sanitarian/EHS office at 812-217-5528 to establish whether sewer connection is required or a septic site evaluation and permit are appropriate435.
- Ask the Building Department at 812-897-6188 which applications and inspections apply, then submit the required house plans121913.
- Budget the published residential permit fee, including the $200 minimum for a single-family dwelling14.
- For access to a state highway, apply through INDOT's Electronic Permit System9.
What should you check before buying land in Warrick County?
Soils: only 4.1% of Warrick County soils rate free of severe limits for a conventional drain field, so get a Health Department site evaluation before relying on a standard septic layout736. Utilities: covered subdivision land without public sewer or water must use an approved private septic system and potable-water source, but a separate county well-permit requirement could not be confirmed3334. Zoning: confirm whether the parcel falls under the county ordinance or the separate rules of Boonville, Newburgh or Chandler37. Land division: covered plats and replats need Area Plan Commission approval before recording, and proposed subdivision parcels cannot be sold before approval and filing8. Flood: Indiana DNR oversees most floodway development, while floodplain-fringe work has no state permit but may still need local approval3839. Access: state-highway driveways need INDOT permission9. Taxes: the median property-tax bill is about $1,497 a year at an effective rate near 0.7%1011.
Watch-outs
- We could not confirm an owner-builder exemption from Warrick County building permits or contractor requirements; ask the Building Department before planning to pull your own building permit613.
- Zoning standards vary by district, and the available ordinance history does not provide every current setback, lot-size or height rule; ask the Area Plan Commission for the current district table262728.
- Only 4.1% of Warrick County soils rate free of severe limitations for a conventional septic drain field, so do not assume a standard system until the Sanitarian/EHS office evaluates your site7.

- Share of soils USDA rates "not limited" for a conventional septic drain field (SSURGO). A strict rating: the median county is about 6% and a tenth of counties are 0%, so a low figure means most lots need a site evaluation or an engineered system, not that septic is impossible.
