Hardie cost in Los Gatos is pushed by wooded foothill exposure, Chapter 7A WUI assembly on most parcels, and premium South Bay estate labor.
The main cost drivers in Los Gatos
Custom estate architecture, Chapter 7A WUI assembly on most parcels, South Bay premium labor, and difficult access on wooded hillside parcels. Each factor pushes the band higher.
Santa Cruz Mountains fringe
Los Gatos sits on the Santa Cruz Mountains fringe with significant wildfire exposure. Chapter 7A applies on most parcels in designated FHSZ; non-combustible Class A cladding is mandatory and the full assembly (vents, eaves, Zone 0) is the honest scope.
Comparing Los Gatos bids
Verify Chapter 7A assembly is itemized, custom trim scope is broken out, and hillside access is reflected. Cladding-only bids on Los Gatos FHSZ parcels are not complete bids.
