ADU Feasibility & Zoning Analysis in San Fernando
The City of San Fernando — a separate incorporated city, not the San Fernando Valley — sizes homes with lot coverage and height, not a FAR (SFMC Ch. 106). ZoneIQ models those standards for your San Fernando parcel and stacks the state-law pathways on top.
What ZoneIQ models in San Fernando
Size & density standards
San Fernando uses NO FAR and no floor-area scale — residential building size is bounded by lot coverage + height + setbacks (SFMC Ch. 106, Table 106-43.2; Ord. 1732, eff. 5-5-2025). R-1 single-family: 50% max lot coverage, 35 ft height (no story cap), 7,500 sf min lot; front 20 ft (subject to a 70%-block-frontage averaging rule), 5 ft sides, 15 ft rear (20 ft where the rear abuts a street or alley). R-2 medium multifamily: 40% coverage, 35 ft, 1 unit per 2,562 sf; R-3 high multifamily: 40% coverage, 45 ft, 1 unit per 1,013 sf — multifamily density is additionally capped by the parcel's General Plan land-use designation (Table 106-43.1).
Local programs
A local Density Bonus applies on top of state law (SFMC Ch. 106, Art. V Div. 13 §§106-1125–106-1131, formerly Art. VI Div. 15 §106-1421); its operative terms (including any local inclusionary requirement) are not modeled — confirm with San Fernando Planning.
Overlays & constraints
The San Fernando Corridors Specific Plan (SP-5, adopted Dec 12, 2017) is a form-based plan along San Fernando Rd, Truman St, Maclay Ave, and First St whose standards SUPERSEDE base zoning — verify whether the parcel is within SP-5. Overlay zones (Residential Planned Development §§106-163–166, Precise Development §§106-167–170, Mixed Use Overlay §§106-171–174) and a Historic Preservation design-review district can also change buildout.
State-law pathways
On top of local zoning, ZoneIQ screens 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. Pathways are shown with statute citations when required source facts are available; otherwise they are suppressed or marked verification-required.
San FernandoADU & zoning FAQ
In most cases, yes — California ADU law applies statewide and preempts many local restrictions. ZoneIQ estimates the maximum ADU (and JADU) size on your specific San Fernando lot in seconds, with the local standards and overlays that bound it, then drafts the permit-application documents.
