Summary
In the City of Blue Springs, Missouri, a retaining wall four feet tall or less, measured from the bottom of the footing to the top of the wall, needs no building permit under City Code Section 500.020(A)(1)(b)(4). Any taller wall, or any wall holding back a surcharge or storing certain Class liquids, must go through the Community Development Department's standard building permit process.
b. Work Exempt From Permit. A building permit shall not be required for the following: ... (4) Retaining walls which are not over four (4) feet in height measured from the bottom of the footing to the top of the wall, unless supporting a surcharge or impounding Class 1, 11 or 111A liquids.
Full Breakdown
Blue Springs folds its retaining-wall threshold into the 2024 International Building Code's Section 105 permit exemptions, adopted locally at Section 500.020(A)(1)(b). A wall stays exempt from a permit only while it is four feet or less measured from the bottom of its footing to the top of the wall, and only if it is not supporting a surcharge or impounding Class 1, 11, or 111A liquids; a wall that crosses either line needs a permit like any other structure covered by Chapter 500. Once a wall requires a permit, the normal Building Code machinery applies: Section 500.070(A) requires the permit before work starts, the fee is set from the Blue Springs Building Permit Fees Table under Section 500.030, and Section 500.090 requires accompanying plans, with commercial project plans signed and sealed by a Missouri-licensed architect or engineer unless the Codes Administrator decides that is unnecessary for the scope of work.
The Codes Administrator, who also serves as the City's Building Official and Chief Building Inspector under Section 500.050, reviews and enforces this permit threshold, and Section 500.100 bars issuing any permit until the submitted plans have been approved.
Violations & Fines
Building or altering a retaining wall above the four-foot exempt threshold without first obtaining a permit violates Section 500.040's general Building Code penalty: a fine up to the amount set in Section 100.080(C), imprisonment of up to ninety days, or both, with each day the unpermitted wall remains standing treated as a separate violation.
