Chillicothe, Missouri routes building-permit applications and building inspections through the city Codes and Zoning Department.1 Chillicothe applies its own zoning inside corporate limits, rather than the rules for unincorporated Livingston County.2 DHSS lists itself as Livingston County’s septic authority, but confirm the permitting route for a Chillicothe address before planning private sewage disposal.3

Do you need a building permit in Chillicothe, MO?
Chillicothe’s Codes and Zoning Department reviews construction drawings and building-permit applications and performs building inspections.1 Chillicothe has adopted the 2021 International Building Code, as amended, with the City Zoning Administrator as code official.4 Call the city office before remodeling or new construction, as the department requests.1 We could not confirm a complete list of residential permit triggers or exemptions; ask the city office about your specific scope, including owner-performed work.1
Who handles Chillicothe building applications and inspections?
The Chillicothe Codes and Zoning Department is at City Hall, 715 Washington; call 660-646-5636 about building-permit applications and inspections.1 The city building-permit application calls for a site plan showing proposed building locations, sizes and measurements from property lines, plus building drawings with structural, electrical and plumbing information.5 Site plans should show existing structures, easements, setbacks and an erosion control plan.5 The application asks applicants to notify the city 24 hours before required inspections; ask the department for the inspection schedule before work begins.5
Does Chillicothe have zoning, and can you live in an RV or tiny home?
Chillicothe zoning governs land and structures throughout the city’s corporate limits, including land legally annexed later.2 Subdivisions, resubdivisions and planned developments must conform to the applicable city zoning-district regulations and other city regulations.7 We could not confirm the detailed Chillicothe rules for residential RV occupancy, temporary camping, tiny homes or accessory dwellings; ask the city Codes and Zoning Department before buying for those uses.2 Request the parcel’s district and the applicable lot-size, setback, height and dwelling-size requirements rather than assuming a small structure is exempt from city regulation.2
How do septic permits work inside Chillicothe?
Missouri requires construction permits before installing or repairing most onsite wastewater systems, although some single-family residential lots may qualify for an exemption.6 DHSS lists itself as the onsite wastewater authority for Livingston County, while incorporated areas may have separate handling.3 Before planning septic inside Chillicothe, ask DHSS to confirm the appropriate permitting authority and ask the city office whether the parcel can use private sewage disposal.3 Do not begin onsite wastewater work until the appropriate authority issues a permit or confirms an exemption.6 DHSS application fees for onsite sewage construction, modifications and repairs are temporarily suspended effective August 28, 2026; confirm current fees when applying.8
Building a home in Chillicothe: what are the steps?
- Ask Chillicothe Codes and Zoning to identify the parcel’s zoning district and review the proposed residential use before preparing the design.2
- Contact the city department before new construction or remodeling and confirm the building-permit scope and inspection schedule.1
- Prepare the site plan and structural, electrical and plumbing drawings requested by the city building-permit application.5
- Resolve sewage disposal with the city and DHSS; if an onsite system is appropriate, obtain the required permit or confirmed exemption before installing it.6
- Arrange required city inspections with the advance notice requested on the application.5
What should you check before buying land in Chillicothe?
For land outside Chillicothe city limits, use the Livingston County guide: county building permits apply to new construction in unincorporated Livingston County, with an agricultural-structure exemption.9 Inside Chillicothe, ask the city office about floodplain review and access requirements before committing to a site plan.5 Missouri requires a permit for constructing or modifying driveways within MoDOT right-of-way; that rule does not establish requirements for every city driveway.10 For budgeting context, Livingston County’s effective property tax rate is 0.9%, a county-level figure rather than a parcel-specific Chillicothe tax quote.11
Watch-outs
- We could not confirm Chillicothe’s RV or tiny-home occupancy conditions; ask City Codes and Zoning before planning to live on a lot while building.2
- Livingston County’s agricultural building-permit exemption applies to unincorporated land; do not use that exemption as approval for construction inside Chillicothe.9
- A septic fee suspension does not remove the requirement to obtain a permit or confirm an exemption before onsite wastewater work begins.86
