Antioch FAQ
Can my HOA force me to maintain a green lawn?
No. California Civil Code 4735 prohibits HOAs from requiring turf during drought and bans penalties for drought-tolerant yards that are adequately maintained.
Do I need a permit to replace my front lawn with gravel and native plants?
For residential properties no permit is required if the footprint is under 500 sq ft or if no irrigation system permit is needed. Check with Public Works if you are modifying storm drainage.
