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.
Sacramento FAQ
How much of my Sacramento lot can I build on?
In R-1 residential zones, structures can cover up to 50% of your lot. This includes the house, garage, ADU, and any covered structures. State law allows an ADU of at least 800 sq ft even if it exceeds this limit.
Does my driveway count toward lot coverage?
No. Uncovered driveways, patios, and hardscape do not count toward lot coverage. Only roofed or covered structures are included in the calculation.
