Building in San Anselmo
Creek adjacency and additions to early-century houses.
Greenport is a design-build general contractor and millwork shop in San Rafael, founded in 2012 by brothers Eli and Jacob Froneberger, both raised in Marin. We hold California General Building license #1073941, and we mill our own casework at 47 Louise St, a short drive from San Anselmo.
Permitting
The Town of San Anselmo Planning and Building Department reviews applications, and properties along San Anselmo Creek carry additional setback and flood requirements.
Housing stock
Craftsman and early-century houses near downtown and Sleepy Hollow, plus hillside houses with detached garages and long approaches.
What decides the schedule
Creek proximity and flood mapping. Both restrict where new footprint can go and how low the floor can sit.
