Does Bellefontaine Neighbors, Missouri have zoning?

Yes. The City of Bellefontaine Neighbors zones its own land under Chapter 29 of the city code, which divides the city into eight districts1. The districts are R-1, R-2 and R-3 single-family, C-1 and C-2 business, PD planned development, and M-1 and M-2 industrial5.

The single-family districts are designated by lot size: R-1 at 20,000 square feet9, R-2 at 10,000 square feet10 and R-3 at 7,500 square feet11. In R-1, an accessory building that is not part of the principal building must sit at least 60 feet from the front lot line12. Land that is unclassified or newly annexed without zoning restrictions is placed in R-19.

We could not confirm building height limits, lot coverage, minimum house size, or rules on RVs, tiny homes, manufactured homes and accessory dwellings. Ask the city's code compliance officer, who handles permits and zoning2.

Do you need a building permit in Bellefontaine Neighbors, and who issues it?

The city's building department lists permits for HVAC, roofing, siding, dumpsters, concrete, excavation and construction, and applications are made in person at City Hall or by mail or drop-box13. Bellefontaine Neighbors has adopted the 2009 International Building Code and International Residential Code2.

A construction permit fee is calculated on the cost of the project: $100.00 for the first $1,000.00 and $5.00 for each additional $1,000.00 or part thereof13.

The St. Louis County building code applies only in unincorporated St. Louis County14. Inside Bellefontaine Neighbors, start with the city's building department, and confirm with City Hall whether any county service is involved in your project, since we could not confirm that. The county's own answer for land outside city limits is on the St. Louis County page.

How do septic permits work in Bellefontaine Neighbors?

Where a public sewer is available, every building with plumbing fixtures must connect to it6. A sewer counts as available when a line sits in a street, alley, right-of-way or easement that adjoins the lot6.

Where no sewer is available, the city code calls for an individual sewage disposal system approved by the city director of public health and sanitation3. The same chapter also refers to county health approval, so the split between city and county is not settled in what we reviewed3. Missouri requires a construction permit before installing or repairing most onsite wastewater systems, although some single-family lots may be exempt15. Ask the St. Louis County Department of Public Health before work begins16.

The state has temporarily suspended application fees for onsite sewage disposal permits as of August 28, 202615.

Building a home in Bellefontaine Neighbors: the steps, in order

  1. Confirm the parcel's zoning district (R-1, R-2, R-3 or another) with the city code compliance officer25.
  2. Check whether a public sewer adjoins the lot6; if not, confirm septic approval with the city and the county health department3.
  3. If you are dividing land, review the city's Chapter 24 subdivision rules7.
  4. Apply for the construction permit at City Hall13.
  5. If the lot touches a floodplain, ask about floodplain rules; the city code has a flood chapter we could not review, and the county's separate floodplain rules apply to unincorporated land17.

What stays with St. Louis County and the state?

Well permits come from the state: Missouri requires a non-restricted permit to construct or repair a water well, and landowners may install their own well or pump without a permit under the cited law4. We could not confirm any additional city well rule.

Septic permitting involves the county health department and, in some cases, the plumbing department18. Driveways onto a state highway need a MoDOT permit19.

St. Louis County's effective property tax rate is about 1.2%8, and the median county property tax bill is $3,193 a year20.

Watch-outs

  • We could not confirm height, lot coverage, minimum house size, RV, tiny home or accessory dwelling rules in Bellefontaine Neighbors; ask the city code compliance officer before buying2.
  • The city's septic rules reference both the city director of public health and county health approval, so confirm which office signs off on your lot3.
  • Sewer connection rules may have moved to the Metropolitan Sewer District; confirm the current rule before relying on the city code6.
