ADU planning guide
ADU Permit Checklist for Los Angeles Homeowners
An ADU permit checklist is useful only if it helps you avoid the common handoff problem: plans that look finished but are not coordinated with engineering, energy compliance, site conditions, utilities, or construction reality.

1. Confirm the property and jurisdiction
Start with the address, governing authority, lot conditions, existing structures, and intended use. Do not assume the same path applies across every LA-area property.
02
2. Choose the ADU direction before drawings
Compare detached ADU, attached ADU, garage conversion, and JADU possibilities. The right path depends on privacy, access, existing structure condition, budget, and long-term goals.

3. Coordinate design, engineering, and energy requirements
Permit-ready plans need more than a floor plan. Structural coordination, energy documentation, utility assumptions, and site details should be resolved before submittal whenever possible.

4. Plan for comments and construction handoff
A good permit process includes responsibility for corrections and keeps construction context attached to the plan set. ADU Powerhouse keeps the same local team involved from evaluation through handover.

Questions homeowners ask

It should include property review, jurisdiction, ADU type, design, engineering, energy compliance, utilities, submittal, corrections, inspections, and construction planning.
Can I start permits before choosing a builder?
