Major concerns

Possible, but hard and costly. Only about 9 inches of rain falls a year, so you will rely on a well (near 70 feet here) or hauled water. The sun is strong, about 6.8 hours of full sun a day, so a smaller solar array covers a household. The U.S. Geological Survey maps strong earthquake shaking here, so build to the seismic code.

Is it legal here?

Zoning
We found no public zoning map for Inyo County, so call the county planning office with the parcel number to ask whether the land is zoned.
Building code
The California Building Standards Code (Title 24) applies statewide and every city and county must enforce it, so a new house needs a permit however remote. A county may adopt the state's optional rules for owner-built rural homes, which relax some standards but still require a permit.
Rainwater
Collecting it is allowed.
Composting toilets
Allowed with a permit and an approved unit.
Water rights
A mix of two systems. Ask the state water office before you drill a well or dam a creek.
