Do you need a building permit in Perryville, MO?

Perryville has a residential building permit process, with construction plans reviewed by the city’s Building Inspector / Zoning Administrator for new development, additions and renovations.¹² Perryville’s published new-residential-construction fee is $0.07 per finished square foot, with a $50 minimum and a $175 maximum; the residential certificate of occupancy fee is $25.¹

Perryville’s building office states that the city enforces the 2021 International Building Code and the 2023 National Electrical Code.² We could not confirm a city owner-builder exemption; ask the building office what your own construction work requires before starting.²

Who issues building permits and schedules inspections in Perryville?

For Perryville building-plan review and construction inspections, contact the Building Inspector / Zoning Administrator at (573) 547-2594 or visit 215 N. West St. Perryville, MO 63775.² Perryville accepts many city applications and payments through the online portal linked from its Applications & Permits page; forms unavailable online can be downloaded and submitted by email or delivered to City Hall.⁷

Call City Hall to arrange construction inspections during normal office hours, and keep the building plans available on site.² A contractor representative must attend inspections, and the required inspections precede the certificate of occupancy needed to occupy the building.²

Does Perryville have zoning, and can you live in an RV or tiny home?

Perryville enforces city zoning ordinances through its Building Inspector / Zoning Administrator.² Ask that office to identify the parcel’s zoning district and confirm the proposed dwelling use, setbacks and lot-size requirements before choosing a house plan.²

Perryville’s residential code requires at least one habitable room of 120 square feet in every dwelling unit; that is a room-area requirement, not a confirmed minimum total house size or approval for tiny-home occupancy.⁶ We could not confirm permission to live in an RV or tiny home on a private Perryville lot; request an address-specific answer from the city zoning administrator.² Perryville prohibits camping on public property, subject to specified authorizations, and city-park overnight camping requires written park-board permission.⁵

How do septic permits work inside Perryville?

Perry County Health Department directs septic applicants to Missouri DHSS following the state’s takeover of septic installs for Perry County in July 2025; start with the DHSS Onsite Wastewater Treatment Program if a Perryville property needs private sewage disposal.³ Contact DHSS at 573-751-6095 or [email protected] to confirm the permitting authority and any exemption for the address.⁸

Missouri requires a construction permit before most onsite wastewater installations or repairs, and work must wait for an issued permit or a confirmed exemption.⁴ Residential property under 3 acres requires a construction permit under the cited state rule, but acreage exemptions do not apply everywhere.⁴ DHSS application fees for construction, modification and repair are temporarily suspended effective August 28, 2026; the suspension does not remove the construction permit requirement.⁹⁴

Building a home in Perryville: what are the steps?

Use Perryville’s city building office for plan review and construction inspections, and Missouri DHSS for questions about a proposed private septic system.²³

1. Ask the city zoning administrator to check zoning compliance for the proposed home and site.²
2. Submit the appropriate city application through the online portal or deliver a downloaded form to City Hall when online submission is unavailable.⁷
3. If private septic is proposed, obtain the construction permit or have the appropriate authority confirm an exemption before wastewater work begins.⁴
4. Schedule city inspections, including foundations with reinforcing in place and open walls before insulation and covering structural members.²
5. Complete required inspections and obtain the certificate of occupancy before occupying the building.²

What should you check before buying land in Perryville?

For land outside Perryville city limits, use the Perry County guide: the county’s no-residential-building-permit answer applies to unincorporated land, rather than replacing Perryville’s city building process.¹⁰¹

For a Perryville parcel, ask the city building office about water and sewer arrangements and driveway curb cuts; we could not confirm the city’s mandatory utility-connection threshold or private-well authorization rule.² Perryville lists a $75 residential driveway curb-cut fee, while entrances connecting to MoDOT right-of-way require the separate MoDOT entrance permit.¹¹¹ Missouri requires a permit for floodplain development, with an engineering No-Rise Certificate required for proposed regulatory-floodway development before the community can issue the floodplain development permit.¹² Ask the city to identify the community floodplain contact for the parcel.²

Watch-outs

• Perryville’s 120-square-foot requirement concerns a habitable room; it does not establish permission to occupy a tiny home on a particular lot.⁶
• Perryville’s prohibition on public-property camping does not answer private-lot RV occupancy; ask the city zoning administrator about the address.⁵²
• Missouri’s temporary DHSS septic application-fee suspension does not authorize starting wastewater construction before a permit or confirmed exemption.⁹⁴
