Do you need a building permit in Miner, Missouri?

Miner has adopted the 2018 International Building Code and International Residential Code, subject to local amendments and provisions for subsequent editions.2 We could not confirm the general building-permit requirement, ordinary construction inspection schedule, certificate-of-occupancy requirement or an owner-builder exemption for Miner; ask City Hall for the requirements for your proposed home, addition or outbuilding.3

The confirmed city approvals are more specific: connecting to Miner public sewer requires a written permit from the inspector, and covered development in the city’s floodplain requires a floodplain development permit.411 Ask for the applicable building-permit application and current code edition before commissioning final plans.3

Who handles building-permit and zoning questions in Miner?

Start with Miner City Hall, whose published telephone number is 573-471-8520.3 Ask City Hall to connect you with the office responsible for building permits, the zoning administrator, the sewer inspector and the city floodplain administrator.3 Request project-specific forms, fees and inspection instructions rather than treating a sewer connection form as a building-permit application.123

Miner’s zoning and construction codes govern the city questions; septic regulation on the Scott County side stays with the Scott County Health Department.125 For property outside city limits, use the Scott County guide for the county contacts and unincorporated-land questions.13

Does Miner have zoning, minimum lot sizes and setbacks?

Miner has its own zoning ordinance, with districts including Agricultural, Single-Family Residential, Multiple-Family Residence, and Manufactured Homes and Parks.14 Ask City Hall to identify the parcel’s zoning district before comparing lot sizes or proposing a different residential use.3

In Miner’s R-2 district, a detached single-family dwelling requires a lot of at least 7,000 square feet; two-family and multifamily structures require 3,000 square feet of lot area per dwelling unit.9 In Miner’s A-1 district, rural non-farm single-family dwellings are permitted on parcels of at least 2.5 acres.10 These are district-specific lot requirements, rather than minimum house floor areas.910 We could not confirm the applicable setbacks, height, lot coverage or minimum dwelling floor area; request the dimensional schedule for your district from City Hall.3

How do sewer connections and septic permits work in Miner?

Miner public sewer connections require a written permit from the inspector, with application on a city-provided form and inspection of the connection under inspector supervision; the owner pays connection costs.412 Ask the city inspector about sewer availability before planning an onsite system.12

Most septic installations and repairs in Miner require a construction permit, and work should wait until the permit is issued or an exemption is confirmed.7 For the Scott County portion, the Scott County Health Department reviews the soil morphology report and application, visits the site, and performs a final inspection after installation.1516 For the Mississippi County portion, ask that county’s Environmental program to confirm whether the county or Missouri DHSS processes the city parcel’s application.6 Missouri’s DHSS-program application fees were temporarily suspended effective August 28, 2026; confirm any local charges with the responsible health department.17

Can you live in an RV or tiny home in Miner?

Miner requires a permit for primitive camping on yards, lots or grounds unless a stated exemption applies; primitive camping means designated campsites without running water and electricity.8 That camping provision does not establish permission to use an RV as a permanent residence.8 Ask City Hall specifically about residential RV occupancy, temporary living during construction and the applicable zoning district.3

We could not confirm a Miner rule specifically authorizing tiny-home occupancy or accessory dwelling units, or a minimum dwelling floor area; ask City Hall to evaluate the proposed dwelling and its location.3 Miner’s adopted residential code and zoning remain relevant to the proposal.21 Include the wastewater plan in that discussion: public sewer connection and onsite sewage construction have separate approval requirements.47

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

  1. Ask Miner City Hall to confirm the parcel’s zoning district, permitted use, dimensional requirements and building-permit application for the proposed dwelling.13
  2. Resolve wastewater service: request the city sewer connection form, or confirm septic jurisdiction and obtain the required permit or confirmed exemption before onsite work begins.12756
  3. Ask the city floodplain administrator whether the site needs a floodplain development permit, including for manufactured-home placement.11
  4. If driveway work enters MoDOT right-of-way, obtain the required state driveway permit; that rule is specific to MoDOT right-of-way.18
  5. Request the city’s construction inspection and occupancy instructions, and arrange the sewer connection inspection or Scott County septic final inspection as applicable.31216

For a private well proposal, ask City Hall about municipal restrictions and the Scott County Health Department about water testing; Missouri’s well-construction and installer-permit rules apply separately.31920

Watch-outs

  • Miner’s agricultural district does not establish a city building-permit exemption; the cited Missouri county agricultural land-use exemption excludes incorporated territory.1021
  • A sewer connection permit is separate from a floodplain development permit for covered development in Miner.411
  • Confirm the septic agency for the parcel’s county before applying: Scott County Health Department regulates the Scott County portion, while the Mississippi County portion needs confirmation of the city allocation.56
