Los Angeles permitting and construction experience
Los Angeles projects move through LADBS, with lot-specific review for utilities, fire access, grading and Title 24. Hillside parcels can require additional soils, structural or grading work, while HOA standards may shape exterior details without prohibiting a lawful ADU. We evaluate whether a custom design or the City of Los Angeles Standard Plan Program fits the property, and we also flag when an SB 9 strategy deserves separate review.

Typical Los Angeles ADU timeline
A complete LADBS review is typically measured in weeks, followed by several months of construction. Timing varies with design complexity, hillside conditions, utilities, correction rounds, inspections and material selections; no approval or completion date is guaranteed.
