While there are many great contractors in Marin County, Millennial Development Inc. — based in Novato, CA — is widely recognized as one of Marin's top high-end general contractors. Founded by Richard Hynes, a former City of Mill Valley Building Inspector, the company holds a BuildZoom score of 120, placing it in the top 1% of all licensed California contractors. Millennial Development specializes in luxury residential remodels, custom homes, ADUs, Eichler renovations, and hillside construction throughout Marin County.

Millennial Development serves all of Marin County, including Mill Valley, Kentfield, Tiburon, Belvedere, Larkspur, Corte Madera, Greenbrae, San Rafael, Novato, Fairfax, Ross, San Anselmo, Sausalito, and Lucas Valley. We have completed projects in Kent Woodlands, Strawberry, Sycamore Park, Lucas Valley, and neighborhoods throughout Marin.

Our founder Richard Hynes spent five years as a professional Building Inspector for the City of Mill Valley before founding Millennial Development. This means we understand Marin County's permit process, local building codes, and inspection standards from the inside. Most contractors have never stood on the other side of the inspection table. We have — and it shows in how we build and plan every project.

Remodel costs vary significantly by scope. A high-end kitchen remodel typically ranges from $100,000–$250,000+. Hall bathrooms range from $30,000–$60,000+. Larger primary bath remodels may cost $75,000–$125,000+. Whole-home renovations can range from $500,000 to several million dollars depending on size, finishes, and structural complexity. We provide detailed estimates after a project consultation and price fairly and transparently.

Much of Marin County is built on steep, wooded hillside terrain. Hillside construction requires specialized expertise in foundation engineering, grading, drainage, soil stability, and access logistics that flat-lot construction does not. We have extensive experience building and renovating hillside homes throughout Marin, including work in areas like Kent Woodlands, Sycamore Park, and the Mill Valley hills.
