Building permits, zoning and septic rules 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 signs⁶. Permitted work must receive the required inspections, and inspection scheduling requires the application number¹. A new house also requires a certificate of occupancy after all final inspections and before anyone occupies the building¹.

The Building Commission serves Evansville and Vanderburgh County and enforces building codes through every phase of residential, commercial and industrial construction⁷. Call the Building Commission at (812) 436-7885 for permit questions⁷. Contractors can request an inspection at (812) 436-7867 or inspectionrequests@evansville.in.gov⁷. The Building Commission directs applicants to contact the Area Plan Commission before requesting a building permit⁷. The Area Plan Commission is in Room 312 of the Civic Center Complex and can be reached at (812) 435-5226⁶. 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 contractors¹.

Yes. Vanderburgh County's zoning ordinance governs county land use, and each parcel's allowed uses and development standards depend on its zoning district². 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 rules². 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 ordinances⁸. For a single-family dwelling, the published minimum floor area is 720 square feet². 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 exceptions². Confirm the parcel's exact district before using those dimensions.

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 Utility¹. The Health Department administers onsite sewage permitting and inspection under state and local requirements³. The office evaluates the site, reviews the soil profile and tailors the system to the home and site³. 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 approval⁴. The Health Department's current FAQ lists a $200 permit, plus $3.95 for credit-card payment, and the permit is valid for one year^5,9. An older Health Department process sheet listed $80 for a residential system, so confirm the current amount when you call⁵. Indiana's state rules prohibit an onsite system where a sanitary sewer is available within a reasonable distance, so check sewer access first¹⁰. 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 price¹¹.

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 land¹². 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 right². Temporary camping also appears to run through the same special-use process². Ask the Area Plan Commission how the parcel's zoning district treats an RV, a tiny home and occupancy during construction⁶. A tiny home proposed as a single-family dwelling must account for the county's published 720-square-foot minimum floor area². 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.

1. Ask the Area Plan Commission to identify the parcel's zoning district, allowed use, lot standards and any subdivision issue before design work begins^2,8.
2. Contact the Area Plan Commission about the required land-use permit before requesting the building permit^6,7.
3. Outside city limits, obtain the county Health Department septic permit; within city limits, obtain the utility's sewer permit¹.
4. If the site is in a flood zone, prepare the certified site grading plan required before the Building Commission can issue its permit¹.
5. Submit the Building Commission application and plans required for the project¹.
6. 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 covering^1,4.
7. For a new house, complete all final inspections and notify the office for the certificate of occupancy before moving in¹.

Confirm the zoning district, permitted use, setbacks, lot coverage and subdivision status with the Area Plan Commission before making an offer^2,8. 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 field¹¹. 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 certificate¹. 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 approval¹³. For road access, ask the government that controls the road; an entrance on a state highway requires permission through INDOT's permit system¹⁴.
