Overview
Traditional Euclidean district-and-overlay code with strong form-sensitive embeddings in NT and Storefront Conservation Corridor districts. Code is explicitly updated bi-annually and includes the recent Ord. 611-H (July 2025) reform of Neighborhood Traditional districts — emphasizing pre-automobile neighborhood patterns (rear alley access, reduced front setbacks, front porches, recognized architectural styles). Peninsular geography drives extreme CHHA exposure; Albert Whitted Airport on downtown waterfront constrains downtown height envelope.

Quirks & notes
Formulas
Definitions
- height
- Building height measured to (a) beginning of roofline (cornice) and (b) top of roof peak; NT/NS/NSM use a stepped-setback schedule keyed to roofline height; special measurement rules apply in NT districts (Ord. 611-H July 2025) and in mapped Albert Whitted Airport Overlay where FAA Part 77 imaginary surfaces apply
- lot_coverage
- Building footprint / lot area; NT districts use 0.55 max residential building coverage (0.60 if one-story principal); separate impervious-surface site-area-ratio cap
- far
- Gross floor area / lot area; FAR includes enclosed space above design flood elevation, excludes enclosed space below DFE plus up to 500 sf of ADU floor area in rear one-third (NT) or first 200 sf of garage per unit (NTM); NT/NTM provide a stacked menu of FAR bonuses up to 0.20
- du_ac
- Dwelling units per gross acre; NT-1/NT-2/NT-4 = 15 (1 principal + 1 ADU per lot); NT-3 = 7; NS-1 = 7.5; NS-2 = 5; NSE = 2; NSM-1 = 15 base, +6 workforce; NSM-2 = 24 base, +6 workforce; NTM-1 = 30; DC-C density-uncapped (FAR-driven)
- setback_front
- Front property line to nearest building face; NT districts emphasize reduced/traditional setbacks per Ord. 611-H; setback minimums step up as roofline height increases
- setback_side
- Interior side and street-side; NS-E uses largest minimums (15-25 ft interior side, 20-30 ft street-side); NT-1/2 minimum 6 ft (lots >60 ft) or 10% lot width (lots <=60 ft)
- setback_rear
- Rear setback varies with alley width; alley-served NT lots use 22 ft including alley width; NS rear setbacks 20-40 ft principal stepped by height
- parking
- Spaces per unit or per 1000 sf per Matrix: Use Permissions and Parking Requirements (§16.10.020.1); minimum 1 space/unit in NTM; reductions apply in DC and under Live Local Act (c§166.04151(7))
