Why Attend Our ADU Seminar

If you’ve been thinking about how to build an ADU on your property, this online session is the perfect place to start. Our live seminar will walk you through everything you need to know about Accessory Dwelling Units—from local zoning rules to design choices and financing options.

You’ll hear from our experienced ADU team, and get a step-by-step breakdown of the process. Whether you’re planning a backyard cottage, a rental unit, or a home for family, our ADU workshop will give you the clarity and confidence to move forward.

This event is ideal for homeowners who want expert guidance on:

  • Understanding ADU building requirements in California

  • Choosing the right size and layout for your property

  • Navigating permits and inspections

  • Estimating costs and timelines for your project

Join us to learn how you can build an ADU that adds value, flexibility, and income potential to your home.

Step Inside a Real ADU

Pictures don’t do it justice. After the ADU seminar, put the design principles you’ve just learned into perspective. Step inside a completed SideHaus ADU and see how thoughtful layout, tall ceilings, and natural light make a small footprint feel surprisingly spacious. It’s a rare chance to experience good design in action — and imagine what’s possible on your own property.
