lot-size-encoded

Lot-size-encoded R-1 series: R-1-6 (6,000 sf min), R-1-8 (8,000 sf min), R-1-10 (10,000 sf min), R-1-X (custom, frozen). R-G Garden Apartments frozen July 2003. Town Center uses TC-P / TC-T. Design review required for all conditional uses and all 2-story R-1 additions.

Worth knowing
  • Lot-size encoded R-1 districts — R-1-6 (6,000 sf), R-1-8 (8,000 sf), R-1-10 (10,000 sf) encode minimum lot area in the district name; R-1-X is custom and frozen (no new R-1-X zones). [confirmed §18.90]
  • R-G Garden Apartments is a frozen district — no new R-G parcels zoned since July 22, 2003. Existing R-G uses R-1-6 side-yard standards for SF and R-2 for duplex. [confirmed §18.90]
  • Design review everywhere — even R-1 two-story additions require design review permits. High threshold compared to most CA cities. [confirmed §18.90]

State preemptions

CA-ADU-GC§66411.7-66411.8applies
Qualifying condition
All CA cities. Fremont's R-1-6/8/10, R-1-X, R-2, R-3, R-G (existing), and mixed-use/Town Center districts must permit ADUs by-right per state law. Fremont's design-review regime for 2-story additions cannot be applied in a way that blocks ADU ministerial approval.
CA-SB9-GC§65852.21-66411.7applies
Qualifying condition
Fremont is a CA general-law city with R-1-6, R-1-8, R-1-10, and R-1-X single-family districts. SB 9 applies per-parcel conditional on exclusions. Fremont contains FEMA flood zones (Alameda Creek, bay-margin tidal areas) that exclude specific parcels, and mapped hillside areas in eastern Fremont that partially overlap CalFire Very High Fire Hazard Severity Zones (check per-parcel). No coastal zone (inland city; bay-margin only). Mission San Jose is a locally designated guidelines area but is not a state-registered historic district — per-parcel check required.
CA-DensityBonus-GC§65915applies
Qualifying condition
Statewide. Applies to any Fremont project meeting affordability thresholds (5% VLI, 10% LI, 10% moderate for-sale, or 100% affordable). AB 1287 allows stacking to achieve up to 100% density bonus.
CA-AB2097applies
Qualifying condition
Fremont is served by BART (Fremont station and Warm Springs/South Fremont station), Amtrak Capitol Corridor (Fremont-Centerville station), and AC Transit bus network with multiple high-frequency corridors (Fremont Blvd, Mowry Ave, Thornton Ave, Mission Blvd). BART stations and Amtrak qualify as 'major transit stops' under PRC §21064.3. AC Transit routes meeting 15-min peak headway also qualify. Parcels within ½ mile of qualifying stops are AB 2097-eligible.
CA-SB423-GC§65913.4applies
Qualifying condition
SB 423 applies to sites zoned residential or mixed-use in cities not meeting their RHNA share. Fremont is under 6th-cycle RHNA (2023–2031) through ABAG/MTC with a 12,897-unit allocation. Per HCD SB 35 Determination dataset, Fremont is subject to SB 423 at the 50% affordability tier (lower-income production lagging). Applies to R-2, R-3, R-G (existing), TC-P, TC-T, CG/CN/CO/CR corridor parcels (per AB 2011 overlap), and Planned-District residential components. VHFHSZ (eastern hillsides) and sites with recent tenant displacement are excluded.
CA-AB2011-GC§65912.100applies
Qualifying condition
Fremont has commercially-zoned parcels along defined corridors (Fremont Blvd, Mowry Ave, Mission Blvd, Thornton Ave, Warm Springs Blvd, Auto Mall Pkwy) that qualify as 'commercial corridors' under AB 2011. 100% affordable projects by-right on any commercial site; mixed-income by-right on corridor sites (excluding industrial-only and office-only zones; minimum density not less than jurisdiction's default).
Non-applicable laws (2)
CA-BuildersRemedy-GC§65589.5(d)(5)confirmed
Qualifying condition
Fremont adopted its 6th-cycle Housing Element (2023–2031) for the ABAG/MTC region. HCD Housing Element Compliance Report shows Fremont with compliance_status = 'In' (reviewed 2023-03-22), record_type = 'Adopted'. Housing element certified compliant — Builder's Remedy not live.
CA-SB10not_applicable
Qualifying condition
SB 10 is permissive — it authorizes but does not require cities to zone up to 10 units/parcel near transit or urban infill via simple resolution (CEQA-exempt). No evidence Fremont has adopted an SB 10 resolution; Title 18 contains no SB 10-adoption reference. Fremont's transit-upzoning vehicles are the TOD parking provisions in §18.90 and Town Center/Planned District rezones — not SB 10.

Quirks & notes

  • Lot-size encoded R-1 districts — R-1-6 (6,000 sf), R-1-8 (8,000 sf), R-1-10 (10,000 sf) encode minimum lot area in the district name; R-1-X is custom and frozen (no new R-1-X zones). [confirmed §18.90]
  • R-G Garden Apartments is a frozen district — no new R-G parcels zoned since July 22, 2003. Existing R-G uses R-1-6 side-yard standards for SF and R-2 for duplex. [confirmed §18.90]
  • Design review everywhere — even R-1 two-story additions require design review permits. High threshold compared to most CA cities. [confirmed §18.90]
  • R-3 adjacency setback doubles — side/rear goes from 10 ft to 20 ft when site adjacent to low-density residential GP (≤8.7 DU/ac). Accessory structures remain at 10 ft. [confirmed §18.90]
  • Rear/side yard substitution flexibility — rear and side yard requirements can be swapped per §18.90 Note 6. Corner lots restricted to rear↔interior-side only. [confirmed §18.90 Note 6]
  • Combination 1/2-story setbacks — each portion meets its own story's setback; wider setback goes on 2-story side; total side yards never less than 1-story requirement. [confirmed §18.90 Note 7]
  • Mission San Jose Guidelines Area imposes additional setbacks beyond base zoning — guidelines document supersedes base where more restrictive. Mission San Jose historic commercial core is also TC-P. [confirmed §18.90, §18.45]
  • TOD parking ceiling — R-3 parking near BART has both a MINIMUM and a MAXIMUM; non-TOD R-3 has minimum only. Reverses normal one-sided parking regulation. AB 2097 further eliminates minimum within ½ mi. [confirmed §18.90]
  • Land use range enabler — R-1-6/8/10 parcels (pre-2005, no H-I overlay) can vary lot area, width, and yard in new subdivisions ≥7 lots via planning commission. Allows density increases within GP ranges. H-I-overlaid parcels excluded. [confirmed §18.90]
  • Three specifically-named Designated Neighborhoods — Glenmoor Gardens, Mission Ranch, Mission Palms each operate as distinct overlays (not a single grouped overlay) with alternative roof-ridge height measurement per §18.90 Notes 8, 10. [confirmed §18.90 Notes 8, 10]
  • Four Town Center historic cores — Centerville, Irvington, Mission San Jose, Niles — are each mapped TC-P districts; Warm Springs is mapped TC-T. TC functions as base replacement rather than pure overlay. [confirmed §18.45]
  • codepublishing.com/CA/Fremont returns 403 Forbidden to scripted WebFetch. Table 18.90.040 (R-1 dimensional standards) and Table 18.45.020 (commercial dimensional standards) require browser-based retrieval.
