The state’s laws encourage ADU development, but local regulations can vary, highlighting the importance of working with a knowledgeable contractor.

Why Choosing the Right ADU Contractor is Important?

The right contractor ensures your ADU project is completed efficiently, compliantly, and to your satisfaction. They navigate the complexities of permits, design, and construction, avoiding costly mistakes and delays. 

A trusted ADU contractor in California will also understand local zoning laws, maximizing your project’s potential.

Steps to Choose an ADU Contractor

The following steps will help you find a suitable ADU contractor in California for your project:

  1. Research and Referrals: Start with online research and seek referrals from friends or family who’ve completed similar projects. Look for contractors with specific ADU experience in California.
  2. Check Credentials: Ensure the contractor is licensed, insured, and has a clean record with California’s licensing board. This step is crucial for legal and safety reasons.
  3. Review Their Portfolio: Assess their previous ADU projects to gauge their expertise, design style, and quality of work. This will give you insight into whether they’re a good fit for your vision.
  4. Get Multiple Bids: Request detailed bids from several contractors to compare costs, timelines, and the scope of work. Be wary of bids that seem too low, as they may indicate shortcuts or hidden fees.
  5. Conduct Interviews: Meet potential contractors to discuss your project in detail. This is a chance to assess their communication skills, professionalism, and understanding of your goals.
