    • Portfolio: Review the contractor’s previous work to ensure their style and quality align with your vision.
    • Licensing: Ensure the contractor is licensed to operate in California, indicating adherence to legal and safety standards.

      I recently worked with Golden State ADU's to build an Accessory Dwelling Unit (ADU) on my property, and I couldn’t be more pleased with the outcome. From start to finish, they were professional, communicative, and attentive to my needs. The ADU they built is exactly what I envisioned, well-designed, functional, and perfect in size. The attention to detail in the finishes, as well as the quality of materials, was outstanding. It’s clear that Golden State ADU’s takes pride in their craftsmanship, and they ensured that every aspect met high standards. Golden State ADU's exceeded my expectations. If you’re looking to add an ADU to your property, I highly recommend this company for their expertise, quality, and professionalism. I've attached a few photo's on the finished project!

      I worked with GSADUs for our 1200 SF detached ADU. A big selling point for going with them was their interior design package and their higher end finishes that stood out from the other companies I inquired with. From design to construction everything was very organized which made it a very easy process for us. All in all great company to work with for an ADU build.
