Building in Fairfax

Steep parcels and small footprints where every added square foot is negotiated.

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 Fairfax.

Permitting

The Town of Fairfax Planning and Building Department reviews applications, with hillside and tree standards that apply to most parcels above the flat.

Housing stock

Small early and mid-century houses on steep, wooded lots, often modified informally over the years.

What decides the schedule

Unpermitted prior work. Fairfax renovations frequently uncover earlier additions that were never permitted, and resolving them is part of the project, not a surprise at inspection.
