Summary
A retaining wall taller than 4 feet in Killeen must be designed on engineer- or architect-sealed drawings before the city will issue a permit. Code Section 8-191(4) treats tall retaining and masonry walls the same as foundation slab repairs, requiring a state-registered design professional's stamp on the submittal documents.
Section R106.1 of the International Residential Code for One- and Two-Family Dwellings, 2024 Edition, is amended by adding Section R106.1.1.1 to read as follows: "R106.1.1.1 Submittal Documents. Engineered documents are required to perform structural repairs or structural changes to buildings covered by this code to include foundation slab repair projects; including masonry or concrete columns or walls or retaining walls, all over four (4) feet in height."
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 38 Update 1).
Full Breakdown
1, requires "engineered documents" for any retaining wall, masonry column, or concrete wall over four feet in overall height, grouping that requirement with structural repair projects and foundation slab repairs. 1, and again in Section 8-187(4), the parallel amendment to the Existing Building Code. Under the base submittal-documents rule these three sections amend, the design professional must be "an architect or engineer legally registered under the laws of this state" and must affix an official seal to the drawings, specifications and accompanying data before the building official will review the permit application.
The building official retains authority to waive the sealed-drawing requirement only for work found not to need design-professional review to confirm code compliance; that waiver is discretionary and is not available as of right just because a wall is close to the four-foot line. A retaining wall four feet or under does not trigger the engineering-seal requirement under these sections, though it may still need a standard construction permit and inspection like any other structure regulated under Chapter 8, including the form-check placement verification required under Section 8-32 confirming the wall does not encroach into a required setback.
Violations & Fines
Submitting an unsealed design for a retaining wall over four feet, or building one without the required construction permit, is enforced as a general Chapter 8 violation under Section 1-8, punishable by a fine and treated as a continuing offense for each day the noncompliant wall remains standing. Starting the work before a permit issues doubles the eventual permit fee under Section 8-11(b).
