“The most common ADU mistake I see in LA: building to the maximum square footage without asking what the renter actually wants. A well-designed 500 sqft ADU with good natural light, real storage, and in-unit laundry rents for 15% more and stays occupied longer than a poorly designed 750 sqft unit.”
Verify your lot's utility lateral capacities before finalizing your ADU design. Some lots in older Valley neighborhoods have undersized sewer laterals or water service lines that need upgrading to serve a second unit. Discovery at permit submittal creates scope and budget changes; discovery in feasibility planning is manageable.
Most adu construction projects in Van Nuys that involve structural, electrical, plumbing, or mechanical changes require LADBS permits. Working without required permits in Van Nuys 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 adu construction projects in Van Nuys 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 Van Nuys's local conditions, permit office staff, and inspection procedures complete projects faster with fewer complications.
