Building in Grass Valley
Grass Valley is the largest city in Nevada County, with a historic downtown, medical and professional offices, retail centers, schools and a wide range of foothill homes. Foothill properties bring their own conditions: sloped and wooded lots, tighter access for materials and equipment, occasional winter snow at higher elevations, and wildfire-area building requirements for exteriors, vents, roofing and decks where they apply. Permits for work in Grass Valley go through the City of Grass Valley building department (or Nevada County for properties outside city limits), and we handle the applications and inspections as part of the job.
