FAQ
Which permits and approvals should I plan for with a hillside project in Los Angeles?
A hillside project in Encino or elsewhere in Los Angeles is broader than a new house alone. Grading, drainage, Planning overlays, and civil clearances for hillside WORK sit on the path. 121 Design Build, a hillside architect team in Los Angeles, maps those desks before site work locks in.
Direct answer
Plan for grading, drainage, Planning overlays, and related clearances for hillside work.
Hillside architect Los Angeles permits start with the site, not only a floor plan. Encino slope work often needs grading and drainage plans, geotech input, and Planning overlay review when hillside ordinance or related rules apply. That package can support retaining, access roads, drainage improvements, or other hillside work — not only a new dwelling.
121 Design Build treats this as architect-led hillside PROJECT work: site constraints, civil coordination, and agency desks for the slope. That is distinct from hillside home builder permits for one HOUSE. City of LA / local AHJ decides what your APN requires.

Encino hillside project context
An Encino hillside project is site-first, not floor-plan-first.
Encino canyon lots often need stakes, haul-off planning, and drainage that protects neighbors before any framing conversation. Flat Encino streets can still need grading when slope and drainage move soil. City of LA / local AHJ decides.
