What makes Van Nuys different

  • Half-mile transit exemption zeroes out ADU parking requirements across most of Van Nuys.
  • Established alleys make rear-unit access straightforward.
  • Strong resale — multi-gen homes with legal ADUs are increasingly the fastest-moving inventory in 91401 and 91405.

Zoning note: Van Nuys airport noise contours affect a small slice of the neighborhood — check FAA overlay before finalizing design.
