Aaron Weiss, the owner of Arm Builders an LA Design & Building Company, is always helping homeowners realize their home needs. Their LA home with a detached garage fit the bill for a perfect garage conversion. Within their first month of hosting, they earned $3,000 for their 450 square-foot garage conversion.

Weiss says, “It was an empty space and wasn’t being used for anything. It added square footage, adding value to the home.”

Weiss is passionate about remodeling and renovations and excited about the opportunities ADUs create for homeowners. So much so, he decided to convert his own garage to show clients what is possible.

It was very important that the garage conversion had flexibility and wouldn’t impact their lifestyle. With a young family, he wanted the ability to make a passive income, but not at the cost of sharing his home with a long-term tenant. Using short-term guests, Weiss was able to host guests at a convenient schedule, maximize his property, and keep privacy for holidays and family events.

Weiss shares, “I’m very happy [with the results]. Airbnb allows my family to host people that stay for 2-3 days at a time. They are usually out for the day and need a place to stay.”

Arm Builders has completed several additional conversions, which are roughly finished in about 6 months from design to construction. For stand-alone ADUs homeowner can expect a timeline of 8-12 months depending on size on complexity.

4. Customer Approval: After the approval of the layout, they then submit the documents to the city for approval.

Most of Arm Builders conversions range from 400 to 600 square feet, but the maximum is 1200 square feet and depends upon the lot and sizing of the house.
