How many units can a lot hold in JRS-2?
Applying the district's lot-area and density rules (the stricter one wins) to typical lot sizes:
| Lot size | Max units | Rule that limits it |
|---|---|---|
| 5,000 sq ft | 1 | lot 5,000 sqft is under the 6,000 sqft minimum (nonconforming) |
| 7,500 sq ft | 1 | 6,000 sqft minimum lot for 1 unit(s) |
| 10,000 sq ft | 1 | 6,000 sqft minimum lot for 1 unit(s) |
| 15,000 sq ft | 1 | 6,000 sqft minimum lot for 1 unit(s) |
| 21,780 sq ft (½ acre) | 1 | 6,000 sqft minimum lot for 1 unit(s) |
Multi-unit numbers only matter where duplexes or multi-family are allowed above. In Jacksonville the Future Land Use Map category can cap density further, and overlays (Riverside/Avondale, San Marco, Springfield and others) can change the numbers.
Notes from the code
Values from §34-34-(e)(1). 'Lot coverage' here is primary structure plus required driveway; the separate impervious cap is 50%. Short-term vacation rentals are a permitted use (§34-731). ADUs are not among the listed accessory uses. Citywide 35-ft height cap: Jacksonville Beach Charter §52(2)(a) ('no new building height shall exceed thirty-five (35) feet').
Compiled from the official code text (JB LDC §34-34-). Zoning changes by ordinance and parcels can be rezoned — confirm on the official zoning map and with Jacksonville Beach planning staff before you rely on it. Not legal advice.
