Boonville is the Warrick County seat, and that matters more than you might expect when you start a home project here: the county building department and the city planning office are two different desks, in two different buildings, and a lot of projects touch both. Here is what a Boonville homeowner actually needs to know before work starts.
Boonville by the numbers
Boonville is the Warrick County seat, about 17 miles east of Evansville. The 2020 census counted 6,712 residents in the city, with a July 2025 estimate of 6,689 — essentially flat. Warrick County as a whole is the growth story: 63,898 in 2020 and an estimated 66,803 by July 2025, up 4.6%. County offices sit at 107 West Locust Street.
Permits: two offices, not one
City of Boonville — Improvement Location Permit. Required for new residential and commercial structures, described by the city as any structure that adds pavement and/or roofing to the footprint of the property, and for signage. Residential is $50, commercial $100, signs $100 for the first and $10 each additional. You need a scaled drawing showing lot dimensions and the footprint tied to the property lines, plus the application. Planning & Zoning is at 135 South Second Street, (812) 897-1230, zoning@boonville.in.gov, Monday to Friday 8:00–5:00 with a midday close from 12:00 to 1:00. City permit page.
Warrick County Building Department. Enforces building codes across the county and issues remodeling, utility and road right-of-way permits. Office is at 107 West Locust St, Suite 208, Boonville, (812) 897-6188, Monday to Friday 8:00–4:00. One practical detail worth knowing before you print anything: residential plans go in at application time and cannot exceed 11 x 17 inches, because they are scanned. County building department.
The short version: a new slab, a covered structure or anything that adds roofing or pavement to your footprint starts at the city; the build itself is a county building department matter. When in doubt, call both before you schedule a crew — it costs one phone call and saves a stop-work conversation.
Clearing out: Warrick County
Boonville sits in Warrick County, so county clear-out programs — dump days, tire collection, household hazardous waste — run on Warrick’s calendar rather than Evansville’s. As of our last check, no 2026 calendar was findable online for Warrick County, which is worth knowing before you drive somewhere with a trailer. We track every county’s programs and sources on the Tri-State Clear-Out Calendar, and we say plainly when dates have not been posted rather than repeating last year’s.
What the weather does to houses here
Boonville gets the same Ohio Valley pattern as the rest of the Tri-State: humid summers, freeze-thaw winters, and a spring storm season that arrives fast. Practically, that means three things for a homeowner. Outdoor concrete needs proper base prep and drainage away from the house, because freeze-thaw finds every low spot. Gutters and grading matter more than they do in a drier climate. And roofs age from storm events as much as from years — a roof that looks fine from the ground can have lost granules or lifted shingles after a wind event.
Before you dig
Call 811 before any excavation — fence posts and deck footings included. It is free, it is the law, and it is a great deal cheaper than hitting a gas line.
Weather, water and what actually floods here
Boonville is not on the Ohio River — that is the county’s southern edge, at Newburgh. Boonville sits inland along Cypress Creek, and FEMA’s Flood Insurance Study for Warrick County names Cypress Creek as the mapped flooding source near the city, noting park and residential areas within its flood plain. The county’s effective flood maps date to August 2, 2012.
There is no NWS river forecast point on Cypress Creek at Boonville, so creek flooding will not show up on a river gauge the way the Ohio does. Check your own address on the FEMA Flood Map Service Center or the Indiana Floodplain Information Portal. Floodplain development permits come from the Warrick County Area Plan Commission; inside city limits, Boonville Planning & Zoning administers flood plain regulations.
Forecasts and warnings for Warrick County come from NWS Paducah under zone INZ087.
Emergency alerts
Warrick County Emergency Management Agency — Director Matthew Goebel, 107 W. Locust St., Suite 307, Boonville; 812-897-6178, Monday through Friday 8:00am–5:00pm. The county’s outdoor warning sirens are activated for an NWS severe weather warning covering Warrick County, a tornado sighted by a public safety officer, or a trained Skywarn spotter report, and are tested each Saturday at 1:00pm unless weather says otherwise.
A gap worth knowing: the county EMA page does not name a resident sign-up alert system, and we could not confirm one from an official county source. If you want phone alerts, call the EMA at the number above and ask what is currently active rather than signing up through a link you found elsewhere.

How to use this hub
- Read the cost guides for range and cost drivers — not for a local price.
- Sketch your scope: size, finish, must-haves, and any floodplain or drainage constraint.
- Confirm permits with the authority named above for your address, not your neighbor’s.
- Get two or three written quotes through the directory or a match request.
- Compare scopes, not bottom lines — how to read a contractor quote walks through the line items.
