R-8 and higher-density residential zones offer by-right duplex development; R-4/R-2 require conditional use process adding 60–90 days and public hearing risk. Target R-8+ parcels for speed.
Lot size and setback requirements vary by district; verify dimensional table for target parcel before LOI to avoid infeasibility after acquisition.
Parking requirements directly impact site layout and construction cost; confirm off-street parking count and driveway access standards before design.
Design review requirements can add cost and timeline; budget for architectural compliance and potential Design Review Board approval in certain districts.
SB 1352 opens path for higher-density duplex subdivisions on larger parcels; target 4+ acre sites for maximum unit count and reduced per-unit land cost.
