Summary
Residential propane tanks get a double break in St. Louis County's zoning ordinance: they are classified as a no-permit Utility Facility Class I use, and the code's own definition of "Structure" specifically excludes them, so the setback and height rules that govern buildings do not apply to where a tank sits.
Structure - Anything more than 30 inches high placed, constructed, or erected with a fixed location on the ground, including portable buildings, mobile or manufactured homes, signs, earth sheltered homes, and above ground swimming pools. Fences, utility poles, lawn lights, non-commercial communication towers not containing dish antennas, non-commercial wind turbines and related minor equipment, privies, and residential propane tanks shall not be considered structures. W. ... Utility Facilities – Class I – A category of uses that includes but is not limited to: electrical lines, fuel tanks, ham radio towers, outdoor wood boilers 1. ... Allowed – No Permit Required: c. ... Utility Facilities – Class I
Full Breakdown
" Because a residential propane tank is not a "structure" under the ordinance, none of the Article III dimensional standards that govern structures, such as the 10-foot property line setback, the 75-foot shoreline setback or the 35-foot height cap, apply to how close a tank can sit to a lot line or the water. " A homeowner installing a residential LP tank therefore does not need a land use permit, a performance standard permit or a conditional use permit from the county to place it.
This zoning exemption only reaches placement and setbacks; it says nothing about the physical installation, tank sizing or clearance-from-ignition-source rules that Minnesota's fire and propane safety regulations impose separately, and the ordinance does not purport to override those state requirements.
Violations & Fines
Because no zoning permit is required, there is no permit-based violation for placing a residential propane tank itself. General Section 8.2 enforcement still reaches a tank if it is used to disguise or house an otherwise-regulated structure, or if a commercial-scale fuel tank installation is misclassified as "residential" to dodge the Utility Facilities Class II or III review that larger tank farms and bulk storage uses require elsewhere in the ordinance; the Director investigates such disputes and unresolved cases go to the County Attorney as a misdemeanor.
