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
What is the maximum lot coverage in unincorporated Sacramento County?
There is no single countywide lot-coverage percentage. Intensity is controlled by the zoning district's setbacks, height, and density, plus a floor-area-to-lot-area ratio of no more than 2.5:1 for commercial and industrial buildings. Check your zone's Chapter 5 table for specifics.
What is a floor area ratio (FAR)?
FAR compares total building floor area to lot area. Sacramento County Section 5.2.2.C provides that for commercial and industrial buildings the floor area to lot area ratio shall not exceed 2.5:1, capping building bulk relative to lot size.
