What ZoneIQ models in La Cañada Flintridge
Size & density standards
La Cañada Flintridge R-1 house size is governed by the §11.11.050 allowable total floor and solid-roofed area scale: 36% of lot area up to 10,000 sf; 3,600 sf + 23% of the area over 10,000 sf to 15,000 sf; 4,750 sf + 20% of the area over 15,000 sf. There is no FAR or lot-coverage standard. Front setback is a neighboring-block average (never less than 25 ft); first-floor interior side is 10% of average lot width (5–20 ft); rear 15 ft; height 28 ft (32 ft on lots over 10,000 sf AND wider than 65 ft).
Local programs
Affordable Housing Density Bonus per LCFMC Ch. 11.19 applies on top of state law.
Overlays & constraints
Hillside Development standards (LCFMC Ch. 11.35) impose slope-based grading/height/design review on hillside lots, and second-story side-yard step-backs apply — verify if the parcel is hillside or a flag lot.
State-law pathways
On top of local zoning, ZoneIQ models the California state-law pathways that often unlock the most buildout: ADU and JADU rights (Gov. Code Ch. 13), SB9 two-unit construction and urban lot splits, the State Density Bonus (§65915), and SB79 transit-oriented development standards — each shown with its statute citation.
