Overview

This page distills how the Yuba County Development Code (Title 11) sets physical development limits—setbacks, height, lot coverage, floor area ratio (FAR), and density—for projects in the unincorporated areas of Yuba County. Use it with your parcel’s zoning to determine what can be built where, and how big. The Code applies countywide outside incorporated cities and is organized by base districts with countywide rules for measuring and a few important exceptions and overlays layered on top.

Key rule: Required yards are measured from the property line or the back of curb—whichever results in the greater setback. Know which one controls on your frontage before you draw a site plan. (§ 11.03.120)

Countywide measurement rules that affect every district

  • Setback measurement: A required yard is parallel to the corresponding lot line or the back of curb; use the greater distance. Special rules apply for alleys and official plan lines. (§ 11.03.120)
  • Lot coverage: Certain items don’t count, including uncovered decks under 6 ft high, eaves up to 3 ft, one small non-habitable accessory structure (≤120 sf and <8 ft high), and pools/hot tubs without roofs. (§ 11.03.100)
  • Building projections into setbacks: Limited encroachments are allowed (e.g., eaves up to 2 ft; certain stairs/ramps up to 3–4 ft), subject to clear limits. (§ 11.19.090(b), Table 11.19.090-B)
  • Height exceptions: Certain rooftop appurtenances or similar features may exceed base height limits where expressly allowed. (§ 11.19.050)
  • Levee setbacks: No new structures, fences, or pools within 50 ft of the landside toe of a levee. (§ 11.19.090(b))

District-by-district development standards (unincorporated areas)

Agricultural Districts — AE-40, AE-80, AR-5/AR-10, AI-20

  • Purpose and typical uses: Working agriculture and related rural living; limited residential density with agricultural support uses. Verify individual allowed uses with the County.
  • Density: Generally 1 dwelling unit per parcel; agricultural labor housing/caretaker units don’t count toward this density. (§ 11.05.030(A)–(B))
  • Height: The maximum height is typically 35 ft for residential structures, 50 ft otherwise. (§ 11.05.030)
  • Setbacks: Front 30 ft; side varies—on lots <1 acre, 25 ft or 10% of lot width (min 5 ft); on ≥1 acre, typically 30 ft; rear 30 ft. (§ 11.05.030; § 11.19.090)
  • Notes: Reduced lot area may be allowed to match natural/manmade features or for certain ag-industrial separations; clustered development may be allowed. (§ 11.05.030(a))

Rural Community Districts — RE (Residential Estate), RR (Rural Residential), RC (Rural Commercial)

  • Purpose and typical uses: Large-lot homes and supportive rural services within mapped rural communities; RC supports small-scale rural-serving commercial.
  • Density and intensity:
    • RE: 1 unit per parcel; lot size often ≥1 acre; coverage varies by parcel size (≤40% under 1 acre; 25% if larger). (§ 11.06.030)
    • RR: Larger lots (e.g., 5–10 acres); 15% max lot coverage noted. (§ 11.06.030)
    • RC: FAR 0.5 maximum. (§ 11.06.030)
  • Height: 35 ft primary; accessory up to 35 ft where shown. (§ 11.06.030; § 11.19.050)
  • Setbacks:
    • RE/RR: Front/street side often 30 ft (measured from property line or ROW centerline rule); interior side 10–20 ft depending on lot size; rear 25–30 ft; accessory structures slightly less in some cases. (§ 11.06.030; § 11.19.090)
    • RC: Front 15 ft; sides/rear as shown in Table 11.06.030. (§ 11.06.030)
  • Notes: Parcels in RE within Natural Resource land use areas may have subdivision limits; VGB rules may apply. (§ 11.06.030(a))

Residential Districts — RS, RM, RH

  • Purpose and typical uses: RS single-family neighborhoods; RM multifamily neighborhoods; RH higher-density multifamily. Accessory Dwelling Units (ADUs) do not count toward max density. (§ 11.07.030 Additional Regs)
  • Density: Typical ranges shown in Table 11.07.030 include minimums around 0.5 / 3 / 6 / 15 du/ac and maximums around 2 / 8 / 17 / 30 du/ac across the gradation from RS to RH. (§ 11.07.030)
  • Height: Primary 30–50 ft depending on district; accessory typically 15–20 ft. (§ 11.07.030; § 11.19.050)
  • Setbacks (typical):
    • Front/street side: If a detached sidewalk is present, 10 ft from sidewalk edge; with attached sidewalk, 15 ft; with no sidewalk, 15 ft from ultimate ROW and 10 ft from drainage ditch if present. (§ 11.07.030; § 11.19.090)
    • Interior side: About 10 ft (RS) and 5 ft (RM/RH). Rear: about 25 ft (RS), 15 ft (RM), 10 ft (RH). (§ 11.07.030)
  • Transitional edges: Where RH is next to RS, RH height steps down to 30 ft within 40 ft of RS and 40 ft within 50 ft. (§ 11.07.030(3))
  • Residential design notes within the valley growth boundary (VGB): Minimum 20 ft driveway apron for front-loaded garages and other single-family siting controls. (§ 11.07.040(a))

Commercial and Mixed-Use Districts — GC, CMX, NMX, DC, EC

  • Purpose and typical uses: Retail and service (GC); mixed-use corridors (CMX, NMX, DC); employment campus/industrial-leaning commercial (EC).
  • Intensity:
    • FAR: GC 0.5, CMX/NMX/DC/EC up to 1.0 (EC often campus-style with internal roads). (§ 11.08.030)
    • Residential density in mixed-use: CMX allows 10–40 du/ac in mixed-use or 18–40 du/ac if residential-only; NMX 3–20 or 10–20; DC 8–40 or 20–40; EC 16–40. (§ 11.08.030 Additional Regs)
  • Height: GC 35 ft, CMX 45 ft, NMX 35 ft, DC 45 ft, EC 60 ft, with height exceptions possible. (§ 11.08.030; § 11.19.050)
  • Setbacks:
    • Front: 5 ft, or 10 ft if there’s no sidewalk (GC/CMX/NMX/DC). EC: 50 ft perimeter; 0 ft to internal roads. (§ 11.08.030; § 11.19.090)
    • Sides/Rear: Often 0 ft but increase to 5–15 ft when adjacent to a residential district. (§ 11.08.030; § 11.19.090)
  • Parking placement: Front yard parking limited or pushed to side/rear in mixed-use centers; see Table 11.08.030 and county Parking. (§ 11.08.030; § 11.25)

Industrial Districts — IC, IG, IL

  • Purpose and typical uses: Light industrial/service commercial (IC), general/heavier industrial (IG), light industrial/flex (IL).
  • Intensity: FAR max 0.25 (IC); 0.5 (IG/IL). (§ 11.09.030)
  • Height: IC 50 ft, IG/IL 75 ft, subject to height exceptions. (§ 11.09.030; § 11.19.050)
  • Setbacks: Often 0 ft on all sides; transitional edges apply near residential or neighborhood mixed-use with existing housing. (§ 11.09.030)
    • Transitional standards near homes: Industrial height steps to 30 ft within 40 ft, 40 ft within 50 ft, 50 ft within 100 ft; setbacks increase to 15 ft interior side and 20 ft rear along residential boundaries. (§ 11.09.030(1))

Special Purpose Districts — PF (Public Facilities), SE (Sports & Entertainment), SP/CP (Plan Areas)

  • Purpose and typical uses: Government and quasi-public uses (PF); regional entertainment venue along Highway 65 (SE); plan areas (SP/CP) where standards come from adopted plans.
  • Intensity: PF FAR 0.5, SE FAR 0.25. (§ 11.10.030)
  • Setbacks: 0 ft, but increase to 10–20 ft when adjacent to residential districts/uses. (§ 11.10.030; § 11.19.090)
  • Notes: The Highway 65 SE area must comply with Measure R and any applicable development agreements. (§ 11.10.040)
  • SP/CP: Development regulations are set in the adopted Specific or Community Plan; the Code allows more precise density/intensity within plan totals. (§ 11.10.030; § 11.65.050–.070)

Accessory structures, pools, and ADUs that can change your site diagram

  • Accessory structures must meet the zone’s setbacks; within the valley growth boundary, no accessory structures in the front yard setback except decks/patios/fences. One small accessory structure (≤120 sf, <8 ft high) is broadly exempt from setbacks. (§ 11.19.030(c)(4); § 11.03.100)
  • Pools/spas: Not allowed in front or street side setbacks within the VGB; minimum side/rear clearances apply. (§ 11.19.100)
  • ADUs: In agricultural and residential districts, approved ADUs do not count toward the maximum density. (§ 11.05.030(b); § 11.07.030(2))
    • State floor: State law assures an 800 sf ADU with 4‑ft side/rear setbacks under specified conditions; use local and state rules together when siting. (Gov. Code §§ 66321–66323)

Checklist

  • Confirm your parcel is in the unincorporated areas and identify its base zoning and any overlays. (§ 11.01.040)
  • Apply the correct district table (agricultural, rural community, residential, commercial/mixed-use, industrial, special purpose). (§§ 11.05.030; 11.06.030; 11.07.030; 11.08.030; 11.09.030; 11.10.030)
  • Measure setbacks the County’s way (property line vs. back of curb—whichever yields a greater yard). (§ 11.03.120)
  • Check sidewalk condition (detached vs. attached vs. no sidewalk) if in residential districts; it changes the front setback. (§ 11.07.030)
  • Account for transitional standards if your site is next to residential (for RH, industrial, PF/SE, EC). (§§ 11.07.030(3); 11.08.030; 11.09.030(1); 11.10.030)
  • Verify levee proximity—50 ft landside toe setback. (§ 11.19.090(b))
  • Confirm lot coverage calc and any allowed projections into setbacks. (§ 11.03.100; § 11.19.090)
  • For ADUs, apply both the County’s density rule and the state ADU minima (size/setbacks). (§ 11.05.030(b); § 11.07.030; Gov. Code §§ 66321–66323)
  • Ensure parking placement and counts meet county rules; some districts push parking to side/rear. (§ 11.08.030; § 11.25) and see Parking
  • If design is in a commercial/mixed-use area, check if Design Review is required for façades, materials, or site layout. (§ 11.19.030(b))
  • If nonconforming or seeking relief, see Nonconforming Uses and Variances and Exceptions.

Risks & Ambiguities

Issue Why it matters What to verify
Front-yard basis (curb vs. lot line) A 5–15 ft difference can make/break a layout Confirm which rule controls on your frontage. (§ 11.03.120)
Residential sidewalk condition Front setback shifts based on sidewalk type Field-check for detached/attached/no sidewalk. (§ 11.07.030)
Transitional edges Extra height/setback steps near housing Map adjacent zoning/uses within 100 ft. (§§ 11.07.030(3); 11.09.030(1))
Levee proximity 50 ft no-build strip restricts yards, pools, fences Locate the levee toe precisely. (§ 11.19.090(b))
VGB and rural lot coverage Coverage caps and front-yard rules differ Check if your site is inside the VGB. (§ 11.07.040; § 11.19.030)
Mixed-use density bands CMX/NMX/DC allow different ranges by project type Clarify if project is true mixed-use vs. residential-only. (§ 11.08.030)
ADU interplay ADUs don’t count to density but must meet siting Apply both county density and state ADU minima. (§ 11.05.030(b); Gov. Code)

Plain-English Summary

In unincorporated Yuba County, your zone sets the size and placement of buildings—how tall, how close to the street or neighbors, and how much of the lot you can cover. Start with the correct district table, measure setbacks the County’s way, watch for special edges (homes, levees), and apply countywide rules for projections, accessory structures, and parking; then use state ADU safeguards as a floor where you add an ADU.

Frequently asked questions

What can I build on an RS lot in Yuba County?

RS is for single-family homes in unincorporated areas. Typical front setbacks are 10–15 ft depending on sidewalk condition; side ~10 ft and rear ~25 ft; height around 30–35 ft. Always measure from the property line or back of curb—whichever yields a greater setback. (§ 11.07.030; § 11.03.120)

What are standard agricultural setbacks and height limits?

In AE/AR/AI districts, front is generally 30 ft; sides are 25 ft or 10% of lot width (min 5 ft) on <1 acre and 30 ft on ≥1 acre; rear 30 ft. Height is 35 ft for residential structures and 50 ft for others. (§ 11.05.030)

Do commercial mixed-use projects have different setbacks?

Yes. GC/CMX/NMX/DC commonly use a 5 ft front setback (10 ft if no sidewalk) and 0–5–15 ft on sides/rear depending on adjacency to residential. Heights range 35–45 ft, with FAR up to 1.0 in CMX/NMX/DC. (§ 11.08.030)

How close can industrial buildings be to homes?

Industrial districts often allow 0 ft setbacks, but near residential or neighborhood mixed-use with existing housing, setbacks and heights must step back: 15 ft interior side, 20 ft rear, and height tiers of 30/40/50 ft within 40/50/100 ft, respectively. (§ 11.09.030(1))

Are ADUs counted toward residential density?

No. In agricultural and residential districts, approved ADUs don’t count toward maximum density in unincorporated areas. Also apply the state ADU floor (e.g., 800 sf, 4-ft side/rear setbacks, subject to conditions). (§ 11.05.030(b); § 11.07.030; Gov. Code §§ 66321–66323)

How are front setbacks determined on streets without sidewalks?

If there’s no sidewalk, residential fronts are typically 15 ft from the ultimate right-of-way (and at least 10 ft from any drainage ditch). Always confirm the official plan line depth. (§ 11.07.030; § 11.03.120)

Can parts of a building project into a setback?

Yes—limited features like eaves (2 ft), certain stairs/ramps (3–4 ft), and bay windows (2–3 ft) can encroach, subject to strict limits and clearances. (§ 11.19.090(b), Table 11.19.090-B)

Are there special setbacks near levees?

Yes. New structures, fences, and pools must be at least 50 ft from the landside toe of a levee. (§ 11.19.090(b))
