Our Mission

We help create additional homes on residential properties. We strive to build housing solutions that create greater economic freedom, maintain privacy, foster community and increase sustainability in the North Bay (Marin, Sonoma & Napa counties).


Our History

The story of Lilypad Homes began with a divorce. When co-founder Rachel Ginis became a single mother, she found herself with extra space in her Corte Madera home. Always innovating, Rachel converted her master bedroom into a private, independent apartment for rental income. Later when her daughter left for college, Rachel moved into the junior unit and rented out the main home.

The flexibility and economic freedom provided by this apartment inspired Rachel to create the non-profit organization Lilypad Homes (now closed). This .org successfully advocated for new local and state codes to ease the requirements and costs of developing accessory dwelling units, promoted progressive financing programs, and opened doors to housing by encouraging homeowners to create new rental units.

Lilypad’s founders, who met through the non-profit, are now combining their talents into Lilypad Homes LLC as a social enterprise design and consulting firm, specializing in the creation of ADUs and JADUs on single-family residential properties in Marin and Sonoma counties. Our team is dedicated to benefiting our clients and our community through more affordable and flexible housing options.
