Do ADUs require permits in West Hills?

ADUs in West Hills must comply with local zoning regulations, building codes, setback requirements, and utility standards established by the City of Los Angeles. Permit approvals are required because ADUs involve structural construction, electrical systems, plumbing, ventilation, and life-safety requirements. Depending on the project type, homeowners may also need architectural plans, engineering documentation, and inspections throughout the construction process. California ADU laws have expanded opportunities for homeowners to build secondary dwelling units, but compliance with local requirements remains essential. Working with an experienced contractor or design-build team helps simplify the permit process while reducing delays and helping ensure the project meets all applicable standards.
