New construction · Mill Valley

What permits are needed for new construction in Mill Valley?

New construction in Mill Valley requires building, electrical, plumbing, and mechanical permits through City of Mill Valley Planning & Building Department, plus any entitlements (zoning / planning review) triggered by the project. Plan check rigorous on Title 24, structural lateral, hillside grading, and fire-code compliance (Chapter 7A + defensible space).

What changes the answer in Mill Valley.

Most new SFRs in hillside zones require Design Review with the Planning Commission, plus story-pole noticing and arborist review. City of Mill Valley Planning & Building Department schedules inspections through its permit portal; foundation, framing, rough trades, insulation, drywall, and final are the standard hold points for new SFRs in Mill Valley.

  • Mill Valley uses R-1, RSP (Single Family-Planned), and Hillside (R-2H, etc.) districts; nearly all parcels carry slope, tree, and grading considerations.
  • Slope and tree cover constrain virtually every Mill Valley lot — buildable envelope is decided by ridgeline rules, slope-band density, and Heritage Tree ordinance long before zoning setbacks.
  • PG&E electric/gas; Marin Municipal Water District (MMWD) for water; Sewerage Agency of Southern Marin (SASM) and various sanitary districts for sewer.
  • Municipal sewer service in developed Mill Valley parcels; verify lateral condition and any point-of-sale sewer compliance requirement before scoping.
