Overview

This page summarizes the development-standards rules in the City of Upland Zoning Ordinance (Title 17) that directly constrain building massing and placement — setbacks, height, lot coverage, parcel/density limits, and floor-area-ratio (FAR). It is focused on the ordinance language and practical interpretation; it does not cover California Building Standards Code (Title 24) permit or construction rules. For the zoning map and zone definitions see the city's Zoning pages and for related topics see the linked guidance on parking, design review, overlays, ADUs and other topics cited below.

  • First, read the city's zoning summary at Upland Zoning. (/us/california/upland/zoning)
  • When the page cites an ordinance requirement it always identifies the controlling code paragraph (for example, § 17.04.030) and links the file-search source.

Note: links to related local guidance are inline the first time each topic is mentioned: parking, design review, overlays, ADUs, the state building code, landscaping, and variances.

How to read this page

  • Bolded zone names (for example RS-10) and bolded numeric controls (for example 40%) call out the actual Upland code terms and limits.
  • Every specific numeric requirement is grounded to the ordinance with the controlling § cited and the file-search citation placed immediately after it.

District-by-district development standards

RS-20 (Single-Family Residential — 20,000 sq.ft. min)

Purpose and typical uses

  • The RS-20 district is single-family residential with large-lot character; typical uses are single-family dwellings and accessory structures. See the residential development standards table at § 17.04.030.

Key dimensional standards

  • Minimum parcel area: 20,000 sq. ft. (§ 17.04.030, Table 17-04-2)
  • Max lot coverage: 35% (§ 17.04.030, Table 17-04-2)
  • Minimum floor area: 2,000 sq. ft. (§ 17.04.030, Table 17-04-2)

Where it applies

  • Outlying and established large-lot single-family neighborhoods as mapped in the Upland zoning map (Title 17 attachment). (§ 17.01.010)

Practical note

  • Accessory dwelling units (ADUs) remain allowed but must respect the lot coverage caps in this zone when the ADU would increase total coverage beyond 35%; see ADU rules at § 17.37.060(C).

RS-15 (Single-Family Residential — 15,000 sq.ft. min)

Purpose and typical uses

  • Large single-family lots, similar to RS-20 with slightly smaller parcel minimums. See § 17.04.030.

Key dimensional standards

  • Minimum parcel area: 15,000 sq. ft. (Table 17-04-2) (§ 17.04.030)
  • Max lot coverage: 35% (Table 17-04-2) (§ 17.04.030)
  • Minimum floor area: 1,800 sq. ft. (Table 17-04-2) (§ 17.04.030)

Practical note

  • ADU lot-coverage limits referenced above apply in the RS-15 zone per § 17.37.060(C)(1).

RS-10 (Single-Family Residential — 10,000 sq.ft. min)

Purpose and typical uses

  • Standard single-family lots and detached dwellings; see § 17.04.030.

Key dimensional standards

  • Minimum parcel area: 10,000 sq. ft. (Table 17-04-2) (§ 17.04.030)
  • Max lot coverage: 40% (Table 17-04-2) (§ 17.04.030)
  • Minimum floor area: 1,600 sq. ft. (Table 17-04-2) (§ 17.04.030)

Practical note

  • ADUs in RS-10 must not push total lot coverage above the 40% cap (§ 17.37.060(C)(2)) unless state ADU rules limit local controls; see § 17.37.060 for ADU-specific setbacks and size limits.

RS-7.5 and RS-4 (Smaller-lot Single-Family)

Purpose and typical uses

  • RS-7.5 (7,500 sq. ft. min) and RS-4 (4,000 sq. ft. min) support smaller single-family parcel patterns. See Table 17-04-2. (§ 17.04.030)

Key dimensional standards

  • RS-7.5: min parcel 7,500 sq. ft.; max lot coverage 45%; min floor 1,400 sq. ft. (§ 17.04.030)
  • RS-4: min parcel 4,000 sq. ft.; max lot coverage 50%; min floor 1,000 sq. ft. (§ 17.04.030)

Practical note

  • ADU lot-coverage caps for RS-7.5 (45%) and RS-4 (50%) are explicitly referenced in the ADU rules (see § 17.37.060(C)(3–4)).

RM zones (Multifamily: RM-10, RM-20, RM-30, RM-40)

Purpose and typical uses

  • Multifamily residential districts allowing increasing densities and multifamily building types. See § 17.04.030 and Table 17-04-2.

Key dimensional standards and special rules

  • Density limits and lot coverage are established in Table 17-04-2; multifamily units in certain RM zones must provide minimum outdoor-living space standards tied to unit count (ADU rules reference similar open-space minima for multifamily conversions) (§ 17.37.060(D) for ADU-related open space)
  • Maximum heights for MFR (multifamily residential) are generally 45 feet / three stories unless otherwise limited; see the MFR height cap in the municipal code (e.g., § 18.32. series and § 17.10.050 for height measurement rules).

Practical note

  • Multifamily projects may be subject to design review, parking standards (see Vehicle Parking and Loading chapter) and development-review findings. For parking rules see Upland Parking. (/us/california/upland/parking)

Mixed‑Use Zones (examples: C/R MU, B/R MU, C/O MU, C/I MU)

Purpose and typical uses

  • Mixed-use zones combine commercial and residential intensity. See Table 17.05-2 and Table 17.05-3 in § 17.05.030.

Key dimensional standards

  • Floor Area Ratio (FAR) and lot coverage limits vary by mixed-use subzone. Example: B/R MU lists max FAR 0.5 and max lot coverage 45% in Table 17.05-2 (§ 17.05.030, Table 17.05-2).
  • Setbacks and building heights for mixed-use zones are provided in Table 17.05-3 referenced at § 17.05.030(B).

Practical note

  • FAR is formally defined and the calculation instructions are in § 17.10.080 (Determining Floor Area Ratio).

Special Purpose Zones (examples: CA, M, OS, PB/I)

Purpose and typical uses

  • Special purpose zones cover airport compatibility, industrial, open space and business park/industrial districts. See § 17.08.030 for parcel-size, FAR and setbacks.

Key dimensional standards

  • PB/I: minimum parcel area 7,500 sq.ft., FAR 0.5, typical setbacks and max height 45 ft (Table 17.08-3 and § 17.08.030).

Practical note

  • CA zones (Cable Airport) defer to the Cable Airport Master Plan; check that plan for special FAR or height limits (§ 17.08.030, Note).

Transit Overlay (TO)

Purpose and typical uses

  • The Transit Overlay zone adds higher density and height allowances near transit corridors. See § 17.09.050.

Key dimensional standards

  • Maximum density: 30 du/acre north of the Pacific Electric Trail; 40 du/acre south (§ 17.09.050(A)).
  • Building height in TO: 55 feet (§ 17.09.050(E)).
  • Setbacks for TO projects refer to Table 17.05-3 (mixed-use setback table) (§ 17.09.050(C)).

Practical note

  • Projects using TO incentives must meet minimum lot-size thresholds to achieve top densities (one acre for 40 du/ac) (§ 17.09.050(B)).

Specific Plan Overlay Zones (SPR-#)

Purpose and typical uses

  • Specific plan overlays (for example SPR-7, SPR-16) substitute the specific plan document for some development standards; the code instructs to consult the applicable specific plan for land-use and development standards (see § 17.09.040).

Practical note

  • When your property lies in a specific plan area, the specific plan controls—confirm setbacks, height and lot-coverage rules in that plan rather than assuming base-zone standards (§ 17.09.040).

Core statutory controls (quick reference table)

Standard / Topic Typical Upland numeric control (code citation) Code Reference
Residential parcel minima and lot coverage (RS zones) RS-20 min 20,000 sf, 35% coverage; RS-10 min 10,000 sf, 40% (§ 17.04.030, Table 17-04-2) § 17.04.030
ADU setbacks 4 ft side/rear minimum; 25 ft front minimum; corner street side 15 ft (§ 17.37.060(B)) § 17.37.060(B)
ADU lot coverage caps in select zones RS-20/15: 35%; RS-10: 40%; RS-7.5: 45% (§ 17.37.060(C)) § 17.37.060(C)
Transit Overlay density and height 30 du/ac (N); 40 du/ac (S); Height 55 ft (§ 17.09.050(A),(E)) § 17.09.050
Mixed-use FAR examples B/R MU FAR 0.5, C/R MU FAR 1.0 (Table 17.05-2) (§ 17.05.030) § 17.05.030
Height measurement and exceptions Height rules and measurement defined in § 17.10.050; MFR zone max 45 ft / 3 stories referenced in municipal code sections (§ 17.10.050, § 18.32. series) § 17.10.050
Definition of Lot Coverage and FAR rule Lot coverage definition and FAR determination in definitions and § 17.10.080 (FAR) and related definitions (§ 17.10.080, definitions table) § 17.10.080

How the ordinance treats ADUs, urban lot splits and related exceptions

  • ADUs have their own specific rules that impose minimum setbacks of 4 ft on sides/rear and 25 ft front (corner street side 15 ft) and explicit lot-coverage caps by RS zone; see § 17.37.060(B–C). These ADU rules also say lot-coverage or FAR cannot reduce an ADU below 800 sq.ft. in certain circumstances (§ 17.37.060(A)(3)).
  • Urban lot split projects are allowed limited two-unit configurations and carry unit-size, height, setback and parking exceptions aimed at enabling small new units; see the urban lot split chapter (e.g., § 16.48. series and related provisions) for stepback/height rules and parking exceptions (§ 16.48. and § 17.37. cross-references).

Practical guidance

  • If you plan an ADU or lot split, review both the baseline zone standards and § 17.37 (ADU) or § 16.48 (urban lot split) because those chapters expressly override or limit the underlying zone only to the extent described in the ordinance.

Checklist

  • Identify the base zone for the parcel (e.g., RS-10, RM-20, B/R MU) and confirm zoning on the Upland zoning map (§ 17.01.010).
  • Verify parcel-size minimum and max lot coverage in Table 17-04-2 or Table 17.05-2 depending on zone (§ 17.04.030, § 17.05.030).
  • Confirm height and measurement rules in § 17.10.050 and any zone-specific caps (e.g., MFR 45 ft) and overlay allowances.
  • For ADUs, confirm § 17.37.060 setback, size and lot-coverage caps and minimum 800 sq.ft. protections.
  • Check if the parcel is in a Specific Plan or Transit Overlay (see § 17.09.040 and § 17.09.050) — those can change density, FAR or height allowances.
  • Confirm required parking per Chapter 17.22 and any TO exemptions (see Upland Parking). (/us/california/upland/parking)
  • Determine whether design review is required (see the Design Review chapter) and prepare required materials if so (/us/california/upland/design-review).
  • If you anticipate relief from a standard, prepare a variance/exception application and expect findings per Chapter 17.16 (/us/california/upland/variances-and-exceptions).

Risks & Ambiguities

Issue Why it matters What to verify
Overlay or specific plan controls A specific plan or the Transit Overlay can supersede base-zone standards (density, FAR, height) Confirm whether the parcel lies inside an SPR or the TO and use the specific plan / § 17.09.040–050 standards; verify map placement.
ADU vs. base-zone conflicts ADU provisions both limit and pre-empt some lot-coverage/FAR/setback rules but are also constrained by state ADU law Apply § 17.37.060 and compare with state ADU law; where the city conflicts with state ADU protections, state law may control — verify with the jurisdiction.
Height measurement and exceptions How height is measured (grade to peak) affects allowable building envelope Check § 17.10.050 and zone-specific height caps and exceptions (e.g., mechanical penthouses).
FAR application in mixed-use projects FAR calculations may exclude residential floor area for live/work units per the code notes See the FAR definition and calculation rules in § 17.10.080 and Table 17.05-2 notes; confirm unit mix and whether workspace counts.
Site-specific physical constraints (fire hazard, airport compatibility) Special standards (fire-hazard mitigation, airport compatibility) add required measures that influence developable area Check § 16.48.K for urban lot split fire measures and CA zone notes in § 17.08.030; verify with fire and planning staff.

Plain-English Summary

Upland's Zoning Ordinance (Title 17) sets parcel-size minimums, lot-coverage caps, setback rules, height caps and FAR limits by zone: single-family RS zones (RS-20 → RS-4) have explicit parcel minima and lot-coverage percentages in § 17.04.030; mixed‑use and special-purpose districts have their own FAR and setback tables in § 17.05.030 and § 17.08.030; ADUs get special setbacks and coverage rules in § 17.37.060 that can override some base-zone limits. Always verify overlays and specific plans because those often change permitted height/density.

Frequently asked questions

What can I build on an RS-10 lot in Upland?

An RS-10 lot is intended for single-family uses; the ordinance sets a minimum parcel area of 10,000 sq.ft., maximum lot coverage of 40%, and a minimum dwelling floor area of 1,600 sq.ft. per Table 17-04-2 (§ 17.04.030) — accessory buildings and ADUs are allowed subject to ADU rules in § 17.37.060.

What are Upland setback requirements for an ADU?

ADUs that require a permit must have a minimum 4‑ft side and rear yard setback, a 25‑ft front setback (subject to exceptions), and a 15‑ft street‑side setback on corner lots; see § 17.37.060(B). Verify specific front-setback exceptions and existing-location exceptions with planning staff.

What are the MFR height limits in Upland?

Multifamily residential buildings are generally capped at 45 feet / three stories, with height measurement rules and exceptions explained in § 17.10.050 and related MFR sections (see municipal code references in the MFR chapters). Confirm the applicable cap in the specific RM zone or overlay.

How does Upland calculate FAR for mixed-use projects?

FAR rules and the method of calculation are defined in § 17.10.080 and noted in Table 17.05-2; some mixed-use tables exclude certain residential floor area from FAR for live/work units — read the table notes and § 17.10.080 carefully for counting rules.

Do overlay zones change setbacks or heights?

Yes. The Transit Overlay (TO) and Specific Plan overlays can change density, height and setback rules — for example the TO allows up to 55 ft and higher densities (30–40 du/ac) in § 17.09.050; specific plans defer to their own documents (§ 17.09.040). Verify the parcel's overlay status.

Do lot-coverage caps apply to ADUs?

Yes. The ADU provisions explicitly reference maximum total lot-coverage thresholds by zone (for example 35% in RS-20/15, 40% in RS-10, 45% in RS-7.5) and say an ADU cannot cause the lot to exceed those totals (§ 17.37.060(C)). State ADU law may limit some local controls; verify with the jurisdiction.

If my lot is in the Transit Overlay, what density can I build?

Transit Overlay limits are 30 du/ac north of the Pacific Electric Trail and 40 du/ac south of it; to achieve 40 du/ac a minimum one-acre site is required (§ 17.09.050(A–B)).

Are stepbacks or story-step requirements specified for small-lot two-unit projects?

Yes — urban lot-split/two-unit projects have story and stepback rules: on lots smaller than 2,000 sq.ft. a new primary dwelling may be up to two stories or 22 ft with required 5‑ft stepbacks for any second story; see the urban lot split chapter and associated unit standards. Verify the lot-split chapter for all unit-size and height limits (§ 16.48 series).

When does the Specific Plan control instead of the base zone?

If the parcel is within a Specific Plan Overlay area (SPR-#) the code instructs you to “refer to the applicable specific plan document for land use regulations, development standards, and application review procedures” (§ 17.09.040). Always check the specific plan text.

Do I need design review for a new commercial or multifamily building?

Design review requirements and thresholds are handled elsewhere in Title 17 (development‑review and design‑review chapters). Projects that alter site development standards or are in specific areas typically require design review; confirm via the city's design-review chapter and consult the Design Review page.
