Retaining Walls in Oakley, CA
Oakley sits between Antioch and Brentwood along Highway 4, with newer subdivisions and a mix of lots. Whether you're planning a new wall or fixing one, here's what's specific to retaining walls in Oakley.
What the City of Oakley says about retaining walls
The City of Oakley's building permit FAQ on walls lists retaining walls "not over 4 feet in height measured from the bottom of the footing to the top of the wall" (City of Oakley). That is the same four-foot measure used in Brentwood's code. Zoning rules such as setbacks may still apply, so check with the City's Building Division before you build.
Newer neighborhoods and HOAs
Many Oakley homes are in newer subdivisions with HOAs. If yours is, get architectural approval before a wall is built or replaced, and ask the HOA whether grading or drainage on your lot is shared with neighbors, since a retaining wall can affect where water goes.
Not sure of the height? Measure from the bottom of the footing to the top of the wall, not just the part above ground. A contractor can confirm the number.
