Upland — Zoning

Q: What can I build on an R‑1 (RS‑4/RS‑7.5/RS‑10 etc.) lot in Upland?

In Upland the single‑family residential zones (e.g., RS‑4 , RS‑7.5 , RS‑10 , RS‑15 , RS‑20 ) are intended for single‑family dwellings and customary accessory buildings; accessory dwelling units and limited public/quasi‑public uses are allowed subject to the zone’s development standards and ADU rules § 17.04.010 and Table 17.04‑3 .

Q: Does the zoning code set industrial buffers to protect adjacent houses?

Yes. Industrial buffer yards are required (a 25‑foot buffer and masonry wall etc.) where industrial development is adjacent to residential uses; details in § 17.07.050 .

Overview

This page summarizes what Upland's Zoning Ordinance (Title 17) actually says about zoning: the adopted base zones, the adopted Zoning Map, overlay districts, and the key development/dimensional rules that control what can be built where. Citations below point to the controlling code sections; read these sections and confirm parcel-specific facts with the Development Services Department before filing. See the City's development standards and related topics for permitting and technical requirements: Upland Development Standards, Upland Parking, Upland Design Review, Upland Overlay Districts, Upland ADUs, and the California Building Standards Code.

How the ordinance is organized (short)

Title 17 is the Zoning Ordinance and formally adopts the City Zoning Map and the list of base zones and overlay zones (see § 17.01.010 and § 17.03.020) .
Overlay rules are in Chapter 17.09 and modify or add requirements to underlying zones (see Transit, Scenic Corridor, Specific Plans) § 17.09 .
Development standards (setbacks, height, lot size, FAR, density) are organized by zone chapter: residential (Chapter 17.04), mixed‑use (Chapter 17.05), commercial (Chapter 17.06), industrial (Chapter 17.07), and special purpose (Chapter 17.08) (see the cited tables) .

District-by-district breakdown

Below are the base zones listed in Table 17.03-1. For each district I give the ordinance purpose, typical permitted uses (from the code's summaries and use tables), and the key dimensional standards the code calls out. Always verify the exact standards that apply to a particular parcel (split-zoned lots, overlays, specific plans may change the rules) — the Development Services Director interprets boundaries and may require additional findings § 17.02.030 .

Note: the ordinance groups zones; I list each zone symbol in bold and cite the controlling chapter/table below.

Residential zones (Table 17.03-1 / Chapter 17.04)

RS-20, RS-15, RS-10, RS-7.5, RS-4 (single‑family residential tiers) — Purpose: preserve single‑family neighborhood character, ensure light/air/privacy, allow accessory/second units where appropriate § 17.04.010 . Typical uses: single‑family homes, accessory structures, limited day‑care, parks, and publicly‑owned/quasi‑public uses. Key standards: see Table 17.04-3 (setbacks, heights and lot minima; e.g., minimum parcel sizes vary by RS-20 → RS-4) — referenced in Chapter 17.04 and in Table 17.04-3 § 17.04.010/Table 17.04-3 .
Where it applies: residential neighborhoods across Upland as shown on the Zoning Map § 17.03.020 .
MH (Mobile Home) — Purpose and permitted uses oriented to mobile home parks and similar development; minimum site area standards apply § 17.04 .
RM-10, RM-20, RM-30 (multi‑family residential) — Purpose: provide medium/low/medium residential densities. Typical uses: duplexes, small apartment buildings, multi‑family structures; densities are expressed as units/acre in Table 17.04-2 and setback/height in Table 17.04-3. Maximum height caps and unit-size rules for multi‑family are in the residential chapter § 17.04 .

Mixed‑Use zones (Chapter 17.05)

C/R‑MU (Commercial/Residential MU), B/R‑MU (Business/Residential MU), C/O‑MU (Commercial/Office MU), C/I‑MU (Commercial/Industrial MU) — Purpose: allow integrated commercial and residential development with standards for ground‑floor commercial in certain corridors § 17.05.030 . Typical uses: combinations of residential units over commercial space, live/work, offices. Key dimensional standards: see Table 17.05-2 (parcel size and density) and Table 17.05-3 (setbacks & height—front 5 ft, side 5 ft, rear 10 ft, structure/floor limits, and maximum ~4 stories unless CUP) § 17.05.030 . Note: the code requires ground‑floor commercial in parts of C/R‑MU abutting Foothill, Mountain, or Euclid (minimum commercial footprint) § 17.05.030 .

Commercial zones (Chapter 17.06)

NC (Neighborhood Commercial), HC (Highway Commercial), RC (Regional Commercial), OP (Office/Professional) — Purpose: retail, services, offices with scale differences. Typical uses: retail stores, restaurants, service businesses, professional offices. Key standards: Table 17.06-2 sets parcel minima and max FAR; Table 17.06-3 sets minimum setbacks (front/side often 5 ft, rear 10 ft) and max heights (NC 35 ft, HC/RC/OP 40 ft) § 17.06.030 .

Industrial zones (Chapter 17.07)

LI (Light Industrial), GI (General Industrial) — Purpose: manufacturing, warehousing, industrial services. Typical uses: light manufacturing, warehousing, utilities and support services; heavy/impactful uses often require AUP/CUP. Key standards: Table 17.07-2/3 (parcel minima: LI 12,500 sq ft, GI 1 acre; setbacks/height: LI front/side 5 ft / rear 10 ft, GI may have 0 ft setbacks on some sides; max height generally 40 ft) § 17.07.030 . Industrial buffer yard rules (25 ft buffer adjacent to residential) are in § 17.07.050 .

Special Purpose zones (Chapter 17.08)

CA (Cable Airport), PB/I (Public/Institutional), OS (Open Space), M (Mining) — Purpose: reserve land for airports, public uses, parks, mineral extraction. Permits and development standards are tailored: see Table 17.08-2 for parcel/FAR and Table 17.08-3 for setbacks/height (e.g., PB/I min parcel 7,500 sq ft and max FAR 0.5, set-backs often 20–25 ft, height caps 45 ft) § 17.08.030 .

Overlay zones (Chapter 17.09)

AC (Airport Compatibility), SC (Scenic Corridor), SP (Specific Plan), TO (Transit Overlay), etc. Overlays impose additional rules that layer on top of the base zone—e.g., the Transit Overlay caps residential densities (north of Pacific Electric Trail 30 du/ac, south 40 du/ac), limits setbacks/height (55 ft building height in TO) and modifies parking requirements for higher-density multi‑family § 17.09.050 . The Scenic Corridor overlay imposes special setbacks and design findings for Euclid Avenue § 17.09.030 . Specific Plans are enumerated and defer to their specific‑plan documents § 17.09.040 .

Checklist (what an applicant must satisfy to be consistent with Upland zoning)

Confirm the parcel's base zone and overlays on the official Zoning Map (map adopted and incorporated by reference § 17.03.020) .
Verify permitted uses and whether a Zoning Clearance, Administrative Use Permit, Conditional Use Permit, or other discretionary approval is required (see Chapter 17.43 and Table 17.43‑1) § 17.43.020 .
Confirm applicable development standards (lot size, setbacks, height, FAR, lot coverage) in the zone's tables (e.g., Table 17.04‑3, Table 17.05‑3, Table 17.06‑3) § 17.04/ § 17.05/ § 17.06 .
If in an overlay (AC, SC, SP, TO), apply the overlay's additional rules (e.g., Transit density and parking adjustments) § 17.09.050 .
Check for special plan area rules (Specific Plans listed in § 17.09.040) and applicable Specific Plan documents § 17.09.040 .
If requesting deviations (variance, minor adjustment), reference the approval standards in Chapter 17.48/17.44 and be ready for public hearings § 17.48.020/§ 17.44.040 .
Prepare required landscape, parking, and design materials; see Upland Landscaping and Screening, Upland Parking, and Upland Design Review.
Confirm ADU rules and whether ADU sits under the zoning rules or is governed by state ADU law; consult Upland ADUs and state ADU law guidance (local ADU rules appear in zoning/ADU chapter; confirm with staff) .

Risks & Ambiguities

Issue	Why it matters	What to verify
Zoning map boundary ambiguity	Map lines may be "approximate"; the Development Services Director determines exact boundary locations § 17.02.030(C)	Verify exact parcel zoning with Development Services and request an official interpretation if boundary unclear.
Overlays altering standards	Overlays (TO, SC, AC, SP) supersede or add rules (density caps, scenic setbacks, airport compatibility) § 17.09	Confirm which overlays apply to the parcel on the adopted Zoning Map and read the overlay section for exceptions.
Split‑zoned parcels	Parcels with more than one zone ("split zoning") may have mixed standards; the Director determines boundary application § 17.02.030(D)	Verify which portion of the parcel is in which zone and whether a rezoning or lot consolidation is advisable.
Specific Plan areas	Specific Plans list unique standards and may override base zone tables (SPR areas enumerated in § 17.09.040)	If parcel falls inside a Specific Plan, read that specific plan document in addition to Title 17.
Design vs. measurements	Tables reference general measurement rules in Chapter 17.10 (rules of measurement, setbacks, FAR) — the text governs over graphics § 17.10; precise measurement rules affect compliance	Confirm measurement rules in 17.10 and use official interpretations where needed; physical site surveys often required.

Plain-English Summary

Upland's Title 17 formally divides the city into named base zones (for single‑family, multi‑family, mixed‑use, commercial, industrial, and special purpose uses) and overlays (e.g., Transit, Scenic Corridor, Airport) that add rules; each zone has a table of the practical limits you must meet (lot size, setbacks, height, density), and the official Zoning Map tells you which zones/overlays apply to a parcel § 17.03.020, § 17.04–17.09 .

Frequently asked questions

What can I build on an R‑1 (RS‑4/RS‑7.5/RS‑10 etc.) lot in Upland?

In Upland the single‑family residential zones (e.g., RS‑4, RS‑7.5, RS‑10, RS‑15, RS‑20) are intended for single‑family dwellings and customary accessory buildings; accessory dwelling units and limited public/quasi‑public uses are allowed subject to the zone’s development standards and ADU rules § 17.04.010 and Table 17.04‑3 .

What are the Upland setback requirements?

Setback minima are zone‑specific: mixed‑use fronts/sides are commonly 5 ft and rear 10 ft in Table 17.05‑3; commercial zones typically have 5 ft front/side and 10 ft rear (Table 17.06‑3); residential setbacks are in Table 17.04‑3. Always confirm which table applies to your zone and whether overlays impose larger setbacks (e.g., Scenic Corridor on Euclid Avenue) § 17.05.030, § 17.06.030, § 17.04 .

Do I need design review for a new project in Upland?

Design review or development plan review is required for many discretionary projects; Table 17.43‑1 shows when the Development Services Director, Planning Commission, or City Council are the decision authority for permits and design review § 17.43.020 . Also check the zone or applicable specific plan—some zones or specific plan areas require design review by condition.

Are there special rules if my property is near the airport or Foothill/Euclid?

Yes. The ordinance applies airport compatibility rules (AC overlay) and references the Cable Airport Land Use Compatibility Plan; the Scenic Corridor (SC) overlay imposes special Euclid Avenue setbacks and design findings. Overlays modify base zone rules § 17.01.040 and § 17.09 .

How does the Transit Overlay change density and parking?

The Transit Overlay caps residential density (north of Pacific Electric Trail 30 du/ac, south 40 du/ac), allows up to 55 ft heights in certain cases, and reduces common open space requirements for projects above 20 du/ac; also has specific parking rules for multi‑family in that overlay § 17.09.050 .

Where is the official Zoning Map and who maintains it?

The City Council adopts the official Zoning Map and it is incorporated by reference into the ordinance; the Development Services Department maintains and updates an electronic version and makes it available to the public § 17.03.020 .

Can I change my property's zone or the Zoning Map designation?

Yes—rezoning or map amendments may be initiated by the property owner, the Development Services Director, Planning Commission, or City Council; the procedures and application requirements are in Chapter 17.48 (Zoning Map/Text amendments) and require public notice and findings § 17.48.020 .

Does the zoning code set industrial buffers to protect adjacent houses?

Yes. Industrial buffer yards are required (a 25‑foot buffer and masonry wall etc.) where industrial development is adjacent to residential uses; details in § 17.07.050 .

If my lot has two zones (split‑zoned), which rules apply?

For split zoning the Development Services Director determines the location and effect of the zone boundary and how standards apply; the Director’s determination may be appealed under the appeal chapters § 17.02.030(D) .

What rules control ADUs in Upland — do zoning standards still apply?

ADUs are subject to both state ADU law and local zoning requirements; local ADU provisions and how they interact with zoning are in the ordinance and the City’s ADU guidance — consult Upland ADUs and the City’s zoning chapter for ADU references. Verify any special limits under overlays or specific plans (local ADU rules appear in the zoning/ADU chapter — verify with staff) .
