Greenport Construction

Building in Sausalito

Stepped hillside houses reached on foot. Logistics are part of the estimate.

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 Sausalito.

Permitting

The City of Sausalito Community Development Department reviews planning and building, with design review for exterior work and view and height standards on the hillside.

Housing stock

Small hillside houses on steep parcels, many from the early and mid century, plus houseboats and flat-lot properties near Bridgeway.

What decides the schedule

Access again, in the extreme. Stair-only houses mean everything is hand-carried, and crews and material handling are priced accordingly.

Common project types

  • Hillside renovation and structural upgrades
  • Envelope, deck, and stair rebuilds
  • Compact kitchens and space-efficient millwork
  • Additions within height and view limits
