Castro Valley FAQ
Do I have to plant natives?
No, but MWELO requires climate-appropriate species in new and major renovation landscapes, and rebates are tied to low-water-use plant palettes.
Are natives fire-safe?
Many but not all; chamise and dry grasses are flammable, while coast live oak and redwood are relatively fire-resistant; use CAL FIRE Ready For Wildfire plant guidance.
Oakland FAQ
Can my Oakland HOA force me to keep a lawn?
No. California Civil Code 4735 makes unenforceable any HOA rule prohibiting low-water or native plant landscaping. You can replace lawn with natives even if CC and Rs say otherwise.
Does Oakland have a native plant list?
There is no single mandatory list, but the Bay-Friendly Landscape Guidelines and the Creek Protection Ordinance reference locally appropriate California natives.
