Do you need a building permit in Pevely, Missouri?

Start a Pevely building project with the city Code Enforcement office: the city provides a basic application and reviews applications weekly.1 Pevely has adopted building and residential codes, along with electrical, plumbing and other construction codes and local amendments.3 Ask the city Building Official which building applications, plans, fees and inspections your proposed work needs.8

Permission to move in is a separate checkpoint: Pevely requires a certificate of occupancy, and new construction, alterations or a change of use require a certificate of use and occupancy under the Building Code before an occupancy permit is issued.7

Who handles building applications and zoning in Pevely?

Contact Pevely Code Enforcement at 636-475-4452 ext 120 for application questions.1 The city says applications are reviewed once a week and applicants are contacted when approved applications are complete and ready for pickup; weekly review is not a promise of weekly approval.1

Pevely’s Code Enforcement and Building Department also covers zoning issues, occupancy inspections and building inspections on decks, sheds, pools, fences and driveways.8 Bring the parcel location and proposed use when asking about zoning or construction approval.8 For utility service, contact the Pevely Utility Department, whose work includes starting and ending service and scheduling building occupancies.9

Does Pevely have zoning, lot-size rules and setbacks?

Pevely has city-administered zoning, and the zoning map is available for examination at City Hall.2 Confirm the district before treating any residential standard as the rule for a particular parcel.2

In Pevely’s R-1 Low Density Residential District, a single-family dwelling needs a lot of at least 1 acre and a minimum lot width of 100 feet; qualifying lots of record have an exception to those area and width requirements.6 R-1 single-family setbacks are 40 feet front, 20 feet side and 40 feet rear, and the lot-of-record exception does not expressly waive setbacks.10 Buildings, including accessory buildings, may cover no more than 25% of an R-1 lot.11

How do septic permits and sewer connections work in Pevely?

Pevely requires a written permit signed by the Chief Sewer Operator before construction of a private sewage-disposal system.4 The applicant must notify the Chief Sewer Operator for final inspection before covering underground portions.12 Ask the Utility Department to route private sewage questions to the Chief Sewer Operator, and resolve state permitting jurisdiction with the Missouri DHSS Onsite Wastewater Treatment Program before starting work.91314

A qualifying Pevely property abutting a street, alley or right-of-way containing city sanitary sewer must connect at the owner’s expense within 90 days after official notice when the sewer is within 100 feet of the property line.15 Private sewage is the alternative where public sewer is unavailable, subject to city approval and applicable state rules.16

Can you live in an RV or tiny house in Pevely?

Pevely limits tiny houses to eligible locations and excludes them from its agricultural, conventional residential, planned residential, business, industrial and waterfront districts listed in the tiny-house provision.5 A Pevely tiny house is defined as 400 square feet or less, excluding lofts, and maximum occupancy is 2 persons.5 Tiny houses cannot be placed in floodplains or floodways, need an occupancy inspection before residents move in, and cannot be used for short-term lodging.5

We could not confirm whether Pevely allows living in an RV on private land or temporary camping while building; ask city Code Enforcement for the rule governing the parcel and proposed duration before buying an RV for that purpose.8

What steps should you take before building a home in Pevely?

  1. Confirm the Pevely zoning district at City Hall and have Code Enforcement review the proposed use and site layout.28
  2. Resolve sewer availability with the Utility Department; if private sewage is proposed, obtain the city approval and confirm applicable state approval before installation.9414
  3. Submit the city building application and ask Code Enforcement for the project’s required plans, fees and inspection schedule.18
  4. Complete the required occupancy approval before moving in.7

For floodplain land, Missouri requires a permit for development and an engineering No-Rise Certificate for proposed regulatory-floodway development; ask Pevely Code Enforcement about the city floodplain process.178 For property outside Pevely city limits, use the Jefferson County guide for the county building and zoning answers.1819

Watch-outs

  • Pevely’s R-1 lot-of-record exception addresses lot area and width; do not assume the exception also removes setbacks.610
  • A state wastewater exemption or fee suspension does not by itself remove Pevely’s written private sewage permit requirement; ask the Chief Sewer Operator and DHSS about the approvals and fees for your address.420
  • We could not confirm Pevely’s general minimum dwelling size, accessory-dwelling rules or an agricultural building-permit exemption; ask city Code Enforcement before choosing a design.8
