Summary

Houston requires a building permit and code-compliance review to construct any retaining wall, and walls eight feet or taller also need a development plat under Chapter 42's subdivision platting rules.

Full Breakdown

City Code Section 10-2 routes every building permit application involving retaining wall construction to the Planning and Development director for compliance review against Chapters 26, 33 and 42, plus a nonrefundable review fee set by the city fee schedule. Houston has no zoning, so wall placement and height are controlled through this permit-review and platting process rather than a zoning setback. Section 42-22 separately exempts a 'retaining wall, masonry wall or fence under eight feet high' from the citywide development-plat requirement, meaning a retaining wall at or above eight feet triggers development-plat review in addition to the building permit review under Section 10-2.

Violations & Fines

Building a retaining wall without the required permit and compliance review lets the building official issue a stop-work order under Section 10-4; the wall must be brought into compliance or removed, and violations can carry additional Code penalties.

Frequently Asked Questions

Do I need a permit for a small retaining wall in Houston?
Yes. Section 10-2 requires code-compliance review for "the construction of any retaining wall" at any height before the building permit issues, with a review fee.
Does a tall retaining wall need more than a building permit?
Yes. Section 42-22 exempts retaining walls under eight feet from the development-plat requirement, so a wall at eight feet or taller must also go through plat review.
