All districts
Signs are regulated citywide in LDO Chapter 109 (Article I - In General; Process and Overview), which sets permitting requirements (most permanent signs require a construction permit; temporary signs, sign walkers, non-electrified window/shingle/address signs, sun screens, and flags under 6 feet are exempt), sign quality/construction/maintenance standards, sign area and monument-height measurement methodology (Sec. 109-1.8), sign classifications and types with time/place/manner restrictions on temporary signs (Sec. 109-1.9, Table 109-1a), electronic messaging centers, reader panels, comprehensive sign programs, and nonconforming sign provisions. Exact-figure review-gated: this draft confirmed the chapter's structure and general/measurement provisions live this session, but could not independently locate and transcribe the specific by-zone permanent sign area and height limit table (if a single citywide table exists separate from the type-by-type standards in Sec. 109-1.9) in the time available. Confirm the specific sign area, height, and permit standards for your zoning district and sign type with Planning and Zoning (623-222-3000) or the Municode publication before acting.
