General Context RM-11 is a residential zoning district intended for multiple-family residential development with a maximum density around 11 dwelling units per acre (consistent with RM-5, RM-7, RM-9, RM-11, RM-15 designations in the St. Lucie County Land Development Code). Permitted uses are defined in Chapter 3 of the St. Lucie County Land Development Code under “Zoning District Use Regulations.” ?

Land.com RM-11 dimensional basics (helpful for feasibility) From Table 7-10 (RM-11 row): Minimum lot size: 10,000 sf Minimum lot width: 100 ft Minimum road frontage: 60 ft Minimum yards: Front 25 ft, Rear 15 ft, Side 10 ft, Side @ corner 20 ft Max height: 35 ft (with notes/conditions in the table) Max lot coverage by buildings: 40% Land.com A specific permitted use explicitly listed as “permitted” in RM-11 Community residential homes (as defined in the Code) are stated as a permitted use in RM-11 (also listed for RM-5/RM-7/RM-9/RM-15). formbasedcodes.org Unfortunately, specific current county code for RM-11 uses by right is not published in an easily searchable online summary that I could retrieve directly with permitted use listings (the official online Municode St. Lucie County LDC portals list the zoning districts but not the full use tables without a paid or interactive view). Municode Library. However, based on longstanding county practice and historical ordinances (which are generally consistent unless updated): Permitted principal uses likely include: ? Multi-family residential dwellings (apartments, condominiums, duplexes, etc.) as the primary use. LoopNet ? Accessory residential uses (e.g., accessory buildings, recreational facilities) customarily allowed to support multi-family living, subject to code definitions and standards. ? Typical residential-related accessory uses permitted in the county’s residential districts (e.g., common open space, community recreation areas, etc.) under the general accessory use provisions. Common Conditional or Special Uses (Not “By Right”) In most St. Lucie County residential zones including RM classifications, uses not automatically by right but may be allowed with special exception or conditional use approval might include: Community residential homes or group homes above certain sizes. Daycare or institutional uses beyond a strictly residential occupancy. Home occupations with greater impacts. These kinds of uses require additional permits/approval processes (public hearings, special exceptions). ?? Important Notes for Accuracy The official permitted use table for RM-11 in the St. Lucie County Land Development Code needs to be pulled directly from the St. Lucie County LDC (which is online via municode.com but wasn’t accessible for full text extraction in this search). Municode Library For precise, current permitted uses “by right” (year-to-date), it’s best to obtain the county’s official Land Development Code PDF or contact the St. Lucie County Planning & Development Services directly — because the online LDC viewer doesn’t list the full use table without navigating through multiple sections. ??
