Retaining Wall Construction in Pasadena & Los Angeles
Retaining walls are engineered systems — not just landscaping. ATP manages retaining wall construction as part of the construction process — built to structural engineering plans, city-approved permits, and inspected at every required phase.
What Retaining Wall Construction Involves
A retaining wall is a structural system designed to hold back soil and manage grade changes on sloped or hillside lots. On most hillside properties and sites with significant elevation changes, retaining walls are required before foundation work can begin — and must be engineered, permitted, and inspected before they can be backfilled. ATP manages retaining wall construction in coordination with structural and civil engineering plans — ensuring walls are built to engineered specifications, pass city inspection, and are ready for the next phase of site development.

Frequently Asked Questions About Retaining Wall Construction
When is a retaining wall required?
Retaining walls are required when a site has significant grade changes — particularly on hillside and sloped lots where soil must be held back to create a stable building pad or prevent erosion. Most hillside projects require retaining walls before foundation work can begin. ATP reviews your specific site conditions during consultation to determine what is required.
Does a retaining wall require a permit?
Yes. Engineered retaining walls require structural plans, permit submission, and city inspection before they can be backfilled. ATP manages the full permitting and inspection process for retaining wall construction directly.
How does retaining wall construction coordinate with foundation work?
Retaining walls are typically built before or alongside foundation work — they must be completed and inspected before the site can be prepared for foundation construction. ATP coordinates both phases under active project management to keep your project on schedule.
