Can I build a duplex in Mount Juliet?
A duplex is a permitted residential use in the R-10 and RM-8 districts in Table 5-102A; RM-8 also carries a mandatory PUD overlay under the table's footnote 1. A duplex is not listed as a by-right use in the single-family RS districts. In R-10, Table 5-103a requires 7,500 square feet of development area per dwelling unit, so a duplex needs at least 15,000 square feet of lot area. Confirm the parcel's zoning, utility service, lot size, and any PUD conditions before designing a duplex. (Corrected 2026-07-03: the draft omitted the RM-8 duplex permission.)
