How many units can a lot hold in RLD-TNH?
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 | 1,500 sqft minimum lot for 1 unit(s) |
| 7,500 sq ft | 1 | 1,500 sqft minimum lot for 1 unit(s) |
| 10,000 sq ft | 1 | 1,500 sqft minimum lot for 1 unit(s) |
| 15,000 sq ft | 1 | 1,500 sqft minimum lot for 1 unit(s) |
| 21,780 sq ft (½ acre) | 1 | 1,500 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
Townhomes are permitted in RLD-TNH only (§656.305.A.II(a)(2)). Lot rules come from §656.414(a): townhouse lot min 1,500 sq ft; width 15 ft (25 ft end units on buildings of more than 2 units, 20 ft on 2-unit buildings); max coverage 70%; max height 35 ft. The 1,500 sq ft is a per-townhouse-lot minimum, not a density rule. Gross density is capped by the FLUM category (§656.414(a)(6), §656.305.A.II(h)). ADU allowed as an accessory use to a conforming single-family dwelling under §656.403(g): behind the primary structure, footprint <= lesser of 25% of principal GFA or 750 sq ft, not in a required yard, and the property must hold (or have applied for) a homestead exemption. That last condition rules out ADUs on non-homestead investor-owned parcels.
