ADU CONSTRUCTION

Expand Your Space. Increase Your Value. Build Smart.

At Mach 1 Construction Inc., we specialize in designing and building Accessory Dwelling Units (ADUs) that perfectly blend functionality, comfort, and long-term value. Whether you’re looking to create a rental unit, a private suite for family, or simply add usable space to your property, our experienced team delivers every project with precision, speed, and craftsmanship worthy of the Mach 1 name.

ADUs are one of the smartest investments California homeowners can make. They provide:

  • Passive income potential through rental opportunities

  • Flexible living solutions for family, guests, or home offices

  • Increased property value and long-term appreciation

  • Faster approval pathways under updated state ADU laws

  • Attached ADUs – Seamlessly integrated additions to your existing home.

  • Garage Conversions – Transform your unused garage into a modern living space.

  • Junior ADUs (JADUs) – Compact, cost-efficient units perfect for smaller lots or family members.
