Drawings you'll need to submit

Most LA rooftop solar permits issue same-day via SolarAPP+. We generate the site plan + roof plan + fire setbacks — free.

  • Site plan (parcel layout + setbacks)
  • Roof plan
  • Panel layout diagram

PermitPathLA generates the site plan free from your Downey address. The other drawings come from your architect or plan firm — we list pre-approved options in the wizard.

Local quirks

  • Downey Unified school fees apply

    Downey Unified School District (DUSD) charges school facility fees on ADUs over 500 sqft.

  • Apollo site (now Columbia Memorial Space Center) is a real local landmark

    If you're marketing a future ADU rental, the Apollo program history and the Columbia Memorial Space Center are major local identity anchors that draw families.

Run your Downey address through the wizard

We pull your parcel polygon from county GIS, apply Downey ordinance + state baseline rules, generate the site plan, and walk you through the Downey Community Development Department submittal. Free, no signup.
