Our team at LADU has worked with hundreds of Los Angeles homeowners on ADU projects. Time and again, we see the same preventable mistakes derail timelines, blow up budgets, and create legal headaches that could have been avoided entirely.
We put together this free guide to help you navigate the process with confidence — whether you're just starting to explore your options or already have a builder lined up.
What's Inside the Guide
We cover the seven most common — and most costly — mistakes LA homeowners make:
- Mistake #1: Skipping the feasibility check before you invest
- Mistake #2: Underestimating permitting complexity and timelines

- Mistake #4: Poor design decisions that hurt rental income
- Mistake #5: Hiring a contractor without ADU-specific experience

Each section includes what goes wrong, why it happens, and exactly what to do instead — based on real projects from our team.
