“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.
Most custom home design projects in Tarzana that involve structural, electrical, plumbing, or mechanical changes require LADBS permits. Working without required permits in Tarzana creates unpermitted improvement disclosure obligations at sale. Your contractor should pull all required permits before work begins — this protects both your investment and your legal standing.
Verify CSLB license at cslb.ca.gov, request 3+ references from completed custom home design projects in Tarzana or nearby, confirm active insurance and worker's comp coverage, and ensure the contractor can explain the permit process for your specific project. Contractors who know Tarzana's local conditions, permit office staff, and inspection procedures complete projects faster with fewer complications.
