“Clients who build custom homes in LA for the first time are surprised by soft costs: architect (8–12% of construction), engineer (2–3%), geotechnical (0.5%), LADBS fees (1.5–3%), Title 24 compliance, interior design. Soft costs add 15–20% above construction cost. Build that into your total project budget from day one.”
Ask your architect for a 'code analysis' memo before design begins. This document summarizes the applicable zoning code, setbacks, height limits, FAR, lot coverage maximum, parking requirements, and fire zone requirements for your specific parcel. Understanding these constraints at project start prevents late-design discoveries that require significant redesign.
The most common custom home design mistakes in Northridge are: selecting a contractor based on price alone without verifying CSLB license and insurance, approving change orders verbally rather than in writing, and starting work before permits are issued. All three create financial and legal exposure that's avoidable with careful contractor selection and contract management.
