Hidden Hills is a gated equestrian community of approximately 600 homes on large lots in the western San Fernando Valley. The city is entirely residential with no commercial development, and the estate-scale properties, many exceeding 10,000 square feet on multi-acre parcels, create substantial drywall scope on every project. Level 5 finishes, curved and radius walls, and surfaces prepared for specialty decorative finishes are standard expectations.

The community falls within a Very High Fire Hazard Severity Zone, requiring fire-rated assemblies throughout. The city maintains its own building department and the permitting process includes detailed plan review with attention to fire-rated assembly specifications and material selections, reflecting the custom nature of each construction project. Hidden Hills' community design review adds another layer of oversight that can influence finish specifications beyond code requirements. Access through the gated entry requires coordination for material deliveries and crew logistics.
