Xeriscape is a great choice for hot summers once it’s established it’s way less work than lawn.
Very rough cost range (DIY vs hiring):
DIY refresh (plants + mulch/rock + edging): ~$800–$3k
DIY with lots of rock + bigger plants: ~$3k–$8k
Hiring it out / hardscape included (steppers, grading, etc.): ~$8k–$20k+
Maintenance: pretty light. Mostly weeding the first few months, then trimming 1–2x/year and occasional drip checks. After the first season it’s basically “set it and forget it.” https://app.neighborbrite.com/s/a3yxR2pm4kc
