Elk Grove FAQ
Does my driveway count toward lot coverage?
No — lot coverage is about building footprints. Driveways fall under impervious-surface/stormwater rules.
Can I add a large addition if I'm already near the lot-coverage limit?
Not without a variance. Consider an ADU instead — state law protects up to 800 sq ft regardless of coverage.
Isleton FAQ
Does my pool count toward lot coverage?
Pool decks and structures typically count. Water surface usually counts as impervious surface for stormwater but not always for lot coverage. Check Title 3 definitions for your zone.
Can I exceed lot coverage with an ADU?
State law requires cities and counties to allow an 800 sq ft ADU regardless of lot-coverage limits that would otherwise preclude it.
