Summary
Pflugerville enforces the 2021 International Residential and Building Codes as its construction code. Under that code, a retaining wall taller than four feet, measured from the bottom of the footing to the top of the wall, needs a building permit and an engineer-designed plan before construction.
The following codes ... are hereby adopted as the city construction code, which is adopted by reference and made a part of this code as if set forth in full herein. ... (A) The following codes published by the International Code Council: (1) International Building Code, with appendices G, H, and I, 2021 edition. (2) International Residential Code, with amendments, with appendices H and J, 2021 edition.

Full Breakdown
City Code Section 150.02 adopts the 2021 International Building Code and 2021 International Residential Code as Pflugerville's construction code, enforced by the building official through Development Services. The adopted IRC exempts only retaining walls not over four feet, measured from the bottom of the footing to the top of the wall, and not supporting a surcharge; anything taller, or any wall holding back an added load, requires a building permit first. The IBC requires such walls to be designed to resist the applied soil loads, so the city expects engineer-stamped drawings for walls over four feet.
Violations & Fines
Building a retaining wall over four feet without the required permit violates Chapter 150. The building official can order the work stopped and pursue municipal-court fines until the wall is permitted, inspected, and brought into compliance.
