More and more people are looking to expand their living space by adding an accessory dwelling unit, or ADU on their property. Perhaps you have an older relative who needs to be close to family, or you want a pool house or exercise room, or maybe you’re looking for a rental unit to offset your mortgage expenses. Whatever your reason, thanks to recent California legislation adding an ADU on your property has become much less complicated. An ADU can be created from an existing structure such as a garage, or a brand new structure can be built. Contact me for more information regarding ADU specifications in San Diego County.


Despite the streamlined regulations however, the entire process of hiring an architect and builder, obtaining permits, and arranging for utilities can be a bit overwhelming and expenses can easily get out of hand. Enter Mighty Buildings, an innovative construction technology company creating beautiful, affordable and sustainable 3D printed homes using robotics and automation. Mighty Buildings has nine move-in ready models ranging from a studio with prices starting at $186,750 to 1 bedroom, 1 bath homes starting at $221,500 and on up to 1440 sq ft 3 bedroom, 2 bath homes.

The company uses a proprietary Light Stone Material that can be printed in any shape and hardens to a stone-like composite. The material is the only 3D building material to be UL listed. It is 4 X lighter than similar concrete structures, water and fire resistant, and is highly energy efficient. Click here to learn more about their technology.

The company manages everything from a feasibility study and site assessment to permits, utilities, delivery and assembly and all interior finishes including kitchen and bathroom(s). When they are done, your ADU is ready to move-in and enjoy! The larger units may also be suitable as a single family home or vacation getaway on a vacant lot.

Steele Group Realty is a Mighty Buildings marketing partner. To learn more or schedule your no-obligation feasibility study, or explore vacant lots in the county, please contact Marti at 619-846-9249 or via email
