Summary
Pearland exempts retaining walls up to 4 feet tall, measured from the bottom of the footing to the top of the wall, from building permit requirements under its locally amended 2021 International Building and Residential Codes. Walls taller than 4 feet, or any wall carrying a surcharge load, need a permit from the city's Division of Permits and Inspections before work starts.
R105.2 Work exempt from permit. Exemption from permit requirements of this code shall not be deemed to grant authorization for any work to be done in any manner in violation of the provisions of this code or any other laws or ordinances of this jurisdiction. Permits shall not be required for the following: Building: 1. One-story detached accessory structures, provided that the floor area does not exceed 200 square feet. 2. Retaining walls that are not over 4 feet in height measured from the bottom of the footing to the top of the wall, unless supporting a surcharge.

Full Breakdown
Pearland adopts the 2021 International Building Code for commercial work under Article II, Sec. 7-13, and the 2021 International Residential Code for one- and two-family homes under Article VII, Sec. 7-81, both most recently amended by Ord. No. 1296-2024, adopted January 22, 2024. Sec. 2, and Sec. 2, both titled Work Exempt From Permit. Each version lists a retaining wall not over 4 feet in height, measured from the bottom of the footing to the top of the wall, alongside small accessory sheds and water tanks under 5,000 gallons as work that does not require a permit.
1. The commercial version adds a second trigger the residential version does not: a wall impounding Class I, II, or IIIA liquids loses the exemption regardless of height, because those flammable and combustible liquid classes carry added life-safety risk. 1 before the building official can approve any modification. The 4-foot line is the same number on both sides of the code, so a homeowner terracing a backyard slope and a business owner stepping down a parking lot grade answer to the identical threshold.
Violations & Fines
Building a retaining wall over 4 feet, or one carrying a surcharge, without first pulling a permit is treated as work commenced before a permit issued: Sec. 7-13.1(i) doubles the normal permit fee under the city's amendment to IBC/IRC Section 109.4. The Division of Permits and Inspections can issue a stop-work order and require the wall opened for a footing inspection before signing off, on top of the doubled fee.
