Retaining Walls, Decks and Additions in Hacienda Heights
Retaining walls, raised decks and additions in Hacienda Heights, drawn for Los Angeles County plan check with load paths, drainage and setbacks shown.
Because Hacienda Heights is unincorporated, the permit for a deck, retaining wall or addition there comes from Los Angeles County, and county plan checkers read every structural sheet we submit. They want to see how each load reaches the soil, how water leaves the site, and where the new work sits against the property lines. Our drawings carry those answers from the first submittal.
What the county reviewer reads
For a retaining wall, the county looks at the height measured from the bottom of the footing, the soil it holds back, and anything resting above it, such as a driveway or a deck. A wall carrying that kind of extra weight needs engineered calculations. For a raised deck, the checker follows the path from the boards to the joists, beams, posts and footings, and expects connection hardware called out at each step. Any grading that moves soil around the lot is drawn with finished levels marked.
Inspections in the field
Once the permit is issued, a county inspector visits at set stages. Footing trenches are inspected with steel in place before any concrete is poured. Framing is checked while it is still open, and the final visit confirms that drains, guards and stairs match the approved set. If the lot falls away from the house, the soils engineer may also have to sign off on the bearing ground before forms go in. Nearby Rowland Heights is unincorporated as well and goes through this same county process.
