Do you need a building permit in Vigo County, Indiana?
Yes: Vigo County requires an Improvement Location Permit for construction that adds square footage1. Vigo County's Building Inspections Department enforces county building codes, issues building, electrical, plumbing and demolition permits, and inspects construction14. The statewide 2020 Indiana Residential Code applies to residential construction in Vigo County, while local zoning, permits and inspections remain separate requirements15. Indiana's state design-release exemption for a building used only for agriculture on the land where it stands and not for retail trade does not establish an exemption from Vigo County permits or inspections10. Ask Building Inspections before treating a barn or shed as exempt.
Who is the Vigo County building department and how do you reach them?
The Vigo County Building Inspections Department, at 151 Oak St, Terre Haute, handles building, electrical, plumbing and demolition permits and inspects construction; call (812) 462-336514. An Improvement Location Permit for added square footage is a three-step process involving Area Planning, Building Inspections and the Vigo County Board of Health14. Area Planning is at 159 Oak St; call 812-462-3354 or email areaplan@vigocounty.in.gov with questions about which application to file16. Area Planning is allowed five business days to grant a zoning permit, but other departmental reviews may affect the full project timeline16.
Does Vigo County have zoning?
The Vigo County Unified Zoning Ordinance covers unincorporated Vigo County as well as Terre Haute, Riley, Seelyville and West Terre Haute through the Area Plan Commission and participating municipal bodies2. Dimensional rules are district-specific, not one countywide number: one cited residential district requires at least 5,500 square feet for a single-family lot and 3,500 square feet per dwelling unit for a two-family use4. In that cited district, front setbacks range from 25 feet on a minor or local street to 60 feet on an arterial, with separate side and rear setbacks5. The same district caps principal-building coverage at 40% and requires at least 25% vegetative cover17. Ask Area Planning for the parcel's district before using any of those figures in a site plan16.
How do septic permits work in Vigo County?
Vigo County's local board of health administers Indiana's residential on-site sewage rule through its health officer, and local ordinances may be stricter than the state baseline8. A home that will not connect to sanitary sewer needs a written septic construction permit before residence construction, system installation, repair, replacement or specified related work begins6. The application requires a soils evaluation and written plans, and the local health department must issue or deny it within 45 days after receiving the application and plans6. When installation is ready, notify the health officer under local procedures—or at least 48 hours or two working days before covering subsurface work if no procedure is published—and obtain final approval7. Only 3.8% of Vigo County soils are rated free of severe limits for a conventional drain field, so complete the site evaluation before committing to a house location18. Off-grid sanitation does not avoid this requirement: a dwelling without sewer service must have a septic tank and a nonfailed soil-absorption system19.
Can you live in an RV or tiny home on your land in Vigo County?
Indiana's campground rules do not answer whether you may live in an RV on your own Vigo County parcel20. We could not confirm a general Vigo County rule for private-land RV occupancy, so ask Area Planning how the parcel's zoning district treats the proposed use16. Tiny homes also are not governed by one countywide minimum: dwelling floor-area requirements vary by district, and a cited residential district requires at least 700 square feet, excluding garages, carports and open porches3. A tiny home must also fit the district's lot, setback and coverage rules4517. If a subdivision covered by the ordinance was recorded after its effective date, public or semipublic sewer and water connections may be mandatory21.
Building a home in Vigo County: the steps, in order
- Call Area Planning at 812-462-3354 to identify the zoning district, applicable lot and setback standards, and any flood-zone information required1645.
- Confirm whether the parcel must connect to public or semipublic sewer and water; that connection is mandatory for certain subdivisions covered by the ordinance21.
- If septic is allowed and planned, obtain the soils evaluation and submit the system plans with the construction-permit application6.
- Submit the Improvement Location Permit application for construction adding square footage; Area Planning, Building Inspections and the Board of Health participate in review114.
- Obtain the applicable building, electrical and plumbing permits from Building Inspections14.
- Arrange the septic final inspection before subsurface work is covered7.
- Secure road-access permission from the controlling government and DNR approval for regulated work in a state-waterway floodway2213.
What to check before you buy land in Vigo County
Before buying, ask Area Planning for the parcel's zoning district, allowed use, minimum lot area, setbacks, coverage limit and flood-zone status because those site standards vary by district451716. Confirm whether a covered subdivision must connect to public or semipublic sewer and water before budgeting for a well or septic system21. Where septic is permitted, evaluate the proposed drain field early because only 3.8% of Vigo County soils are rated free of severe limits for a conventional system18. Indiana generally does not require a high-capacity-well permit outside the Great Lakes Basin, but significant withdrawals may require registration and local rules may apply12. Confirm legal road access, floodway approvals and taxes; the effective property-tax rate is about 0.9%, and the median annual bill is about $1,25622132324.
Watch-outs
- A Vigo County project adding square footage goes through Area Planning, Building Inspections and the Board of Health as part of the Improvement Location Permit process14.
- Only 3.8% of Vigo County's soils are rated free of severe limits for a conventional septic drain field, so a site evaluation should happen before you finalize plans, not after18.
- A 700-square-foot dwelling minimum, 5,500-square-foot lot minimum and cited setbacks are district examples, not universal Vigo County standards; get the parcel-specific rules from Area Planning34516.
- We could not confirm a Vigo County owner-builder exemption; ask the Building Inspections Department before assuming you may self-perform work without a licensed contractor9.
