FAQ
Which permits and approvals should I plan for with a hillside home project in Los Angeles?
A hillside home in Encino or elsewhere in Los Angeles usually needs more than a standard building permit. Grading, soils, the hillside ordinance, and LADBS plan check for a HOUSE sit on the path. 121 Design Build, a hillside home builder in Los Angeles, maps those desks before you frame.
Direct answer
Plan for grading, soils, hillside ordinance review, and LADBS for one house.
Hillside home builder Los Angeles permits work starts with the slope. A house on an Encino canyon lot often needs a soils report, grading and drainage plans, and hillside ordinance clearances before LADBS issues a building permit for the dwelling. Retaining walls that hold the house or access may need their own structural permits.
121 Design Build treats this as a HOUSE project — one dwelling, foundations, walls, and roof — not a general hillside site improvement alone. That distinction matters for how LADBS, grading, and Planning see the package.

What sits in a hillside home permit stack
Soils, grading, hillside ordinance, LADBS building, and related desks for a house.
Soils and grading for the house
A hillside Encino house almost always needs a current soils or geotechnical report. That report drives grading quantities, drainage, and how deep foundations and retaining walls go. Grading permits often clear before or alongside the building permit for the dwelling.
Hillside ordinance and Planning
Many Encino and LA hillside lots fall under hillside ordinance or Planning overlays that shape height, grading limits, and haul routes for a new house. City of LA / local AHJ decides what applies to your APN. We coordinate; we do not invent legal conclusions.
LADBS building permit for the house
Architectural, structural, and energy documents for the HOUSE go through LADBS plan check. Retaining walls that support the dwelling, fire sprinklers, and DWP or BOE clearances often ride with that package. Call (424) 600-2100 to scope the desk list for your Encino lot.
Encino hillside house context
An Encino hillside house is not a flat-lot building permit path.
Encino has steep canyon streets where a new house means haul-off, temporary shoring, and tighter access for concrete and lumber. Flat Encino streets can still need soils work, but the hillside ordinance and grading desk show up more often on slope lots. City of LA / local AHJ decides.
Our office at 17801 Ventura Blvd, 2nd floor, Encino, CA 91316 can walk a hillside home permit path from soils through LADBS. Email info@121designbuild.com.
