Vanderburgh County, Indiana requires Building Commission review for most construction, although a yard barn or gazebo no larger than 199 square feet and without utilities does not need that office's permit1. The Area Plan Commission administers zoning and subdivision rules, with separate city and county zoning ordinances2. Septic permits for addresses outside city limits come from the county Health Department, not the Building Commission3.

Do you need a building permit in Vanderburgh County, Indiana?
Yes, for most construction regulated by the Evansville-Vanderburgh County Building Commission1. A yard barn or gazebo of 199 square feet or less with no utilities does not need a Building Commission permit, but the Area Plan Commission may still require its own permit1. Start with the Area Plan Commission because its permits cover new buildings, additions, homes, accessory structures, pools and business signs13. Permitted work must receive the required inspections, and inspection scheduling requires the application number14. A new house also requires a certificate of occupancy after all final inspections and before anyone occupies the building15.
Who issues building permits in Vanderburgh County, and how do you reach them?
The Building Commission serves Evansville and Vanderburgh County and enforces building codes through every phase of residential, commercial and industrial construction16. Call the Building Commission at (812) 436-7885 for permit questions16. Contractors can request an inspection at (812) 436-7867 or inspectionrequests@evansville.in.gov16. The Building Commission directs applicants to contact the Area Plan Commission before requesting a building permit16. The Area Plan Commission is in Room 312 of the Civic Center Complex and can be reached at (812) 435-522613. An owner-builder path is conditional: an owner with more than two residential properties must use a licensed contractor unless the owner lives in the house or plans to live there for two years after completion, and commercial-property owners must use licensed contractors10.
Does Vanderburgh County have zoning?
Yes. Vanderburgh County's zoning ordinance governs county land use, and each parcel's allowed uses and development standards depend on its zoning district45. The Area Plan Commission handles land-use planning for Evansville, Vanderburgh County and Darmstadt, although that shared administration does not mean every municipality has identical rules17. Rezoning decisions are made at public hearings of the Area Plan Commission, City Council, County Commissioners or the Darmstadt Town Board, depending on the parcel2. The commission also administers and enforces subdivision ordinances18. For a single-family dwelling, the published minimum floor area is 720 square feet11. In the A district, the table lists a 6,000-square-foot minimum lot, a 35-foot height limit, 25-foot front and rear yards, a 5-foot side yard, and 30% lot coverage, subject to the table's notes and exceptions19202122. Confirm the parcel's exact district before using those dimensions.
How do septic permits work in Vanderburgh County?
For a new house outside city limits, the Building Commission requirements call for a septic permit from the Vanderburgh County Health Department; within city limits, they instead call for a sewer permit from the Evansville Water and Sewer Utility3. The Health Department administers onsite sewage permitting and inspection under state and local requirements6. The office evaluates the site, reviews the soil profile and tailors the system to the home and site23. For a new, repaired or replacement system, the installer must notify the department 24 hours before completion so staff can inspect system components before they are covered; additional inspections and corrections may be required before approval7. The Health Department's current FAQ lists a $200 permit, plus $3.95 for credit-card payment, and the permit is valid for one year824. An older Health Department process sheet listed $80 for a residential system, so confirm the current amount when you call9. Indiana's state rules prohibit an onsite system where a sanitary sewer is available within a reasonable distance, so check sewer access first25. Only about 12% of county soils rate free of severe limitations for a conventional drain field, so evaluate septic feasibility before fixing the house location or price26.
Can you live in an RV or tiny home on your land in Vanderburgh County?
We could not confirm a Vanderburgh County rule allowing long-term RV occupancy, temporary camping or tiny-home occupancy on a private parcel. Indiana's campground rule addresses regulated campgrounds rather than residential use of an individually deeded lot, so it does not answer whether an owner may live in an RV on private land27. The county's zoning table treats accessory living quarters (not for rental) and mobile home parks as special uses that need Board of Zoning Appeals approval and a public hearing, so a second dwelling or manufactured home is not simply allowed by right2829. Temporary camping also appears to run through the same special-use process30. Ask the Area Plan Commission how the parcel's zoning district treats an RV, a tiny home and occupancy during construction13. A tiny home proposed as a single-family dwelling must account for the county's published 720-square-foot minimum floor area11. Do not assume a wheeled unit, manufactured home or accessory dwelling qualifies as a conventional single-family house; ask the commission to identify the applicable use and approval path for the exact unit.
Building a home in Vanderburgh County: the steps, in order
- Ask the Area Plan Commission to identify the parcel's zoning district, allowed use, lot standards and any subdivision issue before design work begins518.
- Contact the Area Plan Commission about the required land-use permit before requesting the building permit1613.
- Outside city limits, obtain the county Health Department septic permit; within city limits, obtain the utility's sewer permit3.
- If the site is in a flood zone, prepare the certified site grading plan required before the Building Commission can issue its permit31.
- Submit the Building Commission application and plans required for the project1.
- Arrange the required building inspections using the application number, and have the septic installer notify the Health Department 24 hours before completing the system so its components can be inspected before covering147.
- For a new house, complete all final inspections and notify the office for the certificate of occupancy before moving in15.
What to check before you buy land in Vanderburgh County
Confirm the zoning district, permitted use, setbacks, lot coverage and subdivision status with the Area Plan Commission before making an offer5212218. If public sewer is unavailable, make the offer contingent on septic feasibility because only about 12% of county soils rate free of severe limitations for a conventional drain field26. Confirm whether the parcel lies in a flood zone: local permitting then requires a certified site grading plan, and occupancy approval requires a finished elevation certificate31. Most development in an Indiana floodway also falls under DNR Division of Water jurisdiction, while floodplain-fringe work has no state review but may still need local approval3233. For road access, ask the government that controls the road; an entrance on a state highway requires permission through INDOT's permit system34.
Watch-outs
- A utility-free yard barn or gazebo no larger than 199 square feet may skip the Building Commission permit, but the Area Plan Commission may still require its own permit1.
- A new house in a flood zone cannot receive a certificate of occupancy without a finished elevation certificate31.
- Vanderburgh County's owner-builder allowance narrows for owners with more than two residential properties and does not cover owners of commercial property10.

- 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.
