Hesperia FAQ
Can I build a carport in my front yard in Hesperia?
Generally no — accessory structures must meet front-yard setbacks for the underlying zone. Carports are limited to side and rear yard locations under most Hesperia residential zones, subject to the §16.20.400 aggregate area cap of 15% of net lot area.
Does a carport count as covered parking in Hesperia?
Hesperia's residential parking standards generally require enclosed garage parking for single-family homes in most R zones. A carport may not satisfy that requirement except where the zoning code specifically permits 'covered' parking. Verify with the Planning Division before relying on a carport for required parking.
Ontario FAQ

Only with a permit that shows proper engineering and zoning setbacks. Temporary fabric carports are widely prohibited in front yards by HOAs and may be cited as substandard.

Yes, if it meets the minimum 9 foot by 18 foot space size, vertical clearance, and permitted construction. Oversized tandem spaces may also count.
