The Downtown Design Guide (2009, updated 2017) establishes urban form standards under LAMC §12.21 G for Central City, South Park, Bunker Hill, and the Arts District. It mandates ground-floor activation, transparency, and build-to-line requirements for most new development.
The Downtown Design Guide governs site planning, building massing, and street-level design across Downtown LA. Under LAMC §12.21 G, projects must meet build-to-line standards (typically 70 to 80 percent of frontage at the property line), minimum ground-floor transparency (often 75 percent of street wall), active uses on primary streets, and stepbacks above podium heights. Parking entries must avoid pedestrian-priority frontages where feasible. The 2017 update tightened residential ground-floor activation, sidewalk widths, and bird-safe glazing references. Director of Planning review is required for adjustments. The Guide complements the Central City Community Plan and applicable specific plans.
Projects failing Design Guide compliance are denied site plan or planning approval. Unauthorized deviations after permitting trigger stop-work orders and required restoration to approved plans.
