Overview

This page summarizes what Placerville's local zoning ordinance (Title 10) actually says about zoning: how the city defines zones, the major zone-by-zone rules and dimensional standards, and the special overlay districts that change or supplement base zoning. For precise parcel-level answers, always check the official zoning map and the Development Services Department because some rules (overlays, site‑specific HO rezones, ALUCP areas) add or change standards. See the list of zones in § 10‑5‑1 for the official district names and the map-bindary rules in § 10‑2‑4.

Below are the city zones and the provisions the ordinance actually contains. I present the ordinance citation for each district and summarize the ordinance language in plain English rather than reproducing long code text.

Zone list (master reference)

The city’s official zone list (and the exact district labels you will see on the zoning map) is set out in § 10‑5‑1: OS, RE, R‑1A, R‑1 (20,000 / 10,000 / 6,000), R‑2, R‑3, R‑4, R‑5, BP, CBD, C, CC, HWC, HC, I, PF, PD, PDI, AO, HO, CBO.

How to read these district subsections

Each district subsection below lists: purpose (what city intended), typical permitted uses, and the most decision‑relevant dimensional/development standards the ordinance actually sets (minimum parcel area, frontage, setbacks, height, coverage/FAR). Each subsection cites the controlling code section where that material appears.

OS — Open Space Zone

Purpose: preserve undeveloped/open areas and manage uses compatible with open space. See § 10‑5‑3 for details and development limitations.

Typical uses: parks, passive recreation, limited public/quasi‑public facilities (see the OS section for the full list). Key dimensional standards and parking/refuse/landscape rules appear in the OS section (minimum parcel frontage 60 ft is listed).

RE — Estate Residential (rural/large‑lot single‑family)

Purpose and uses: rural/large‑lot single‑family living; see § 10‑5‑6 for permitted uses and minimum parcel limits. Typical standards (minimum parcel area 1 acre, front yard 30 ft, height 35 ft) are in the RE section.

R‑1 (multiple variants) — Single‑Family Residential

  • R‑1, 20,000 — § 10‑5‑6: low‑density single‑family; minimum parcel area 20,000 sq ft, front 30 ft, height 35 ft.
  • R‑1, 10,000 — § 10‑5‑7: moderate single‑family; minimum parcel area 10,000 sq ft, front yard 20 ft, height 35 ft.
  • R‑1, 6,000 — § 10‑5‑8: medium density single‑family; permitted uses include one‑family dwellings, one ADU (see ADU rules) and home occupations; standards include maximum density 7.26 du/acre, minimum parcel area 6,000 sq ft, front setback 20 ft, height 40 ft, frontage 60 ft.

Note: ADUs and Jr. ADUs are explicitly permitted in R‑1 zones subject to the ADU rules in § 10‑4‑12 (see ADU subsection below).

R‑2 / R‑3 / R‑4 — Low / Medium / High‑density Multi‑Family Residential

Each multi‑family range has its own section (§ numbers appear consecutively in Chapter 5). Basic content: permitted multi‑family uses, accessory uses (ADUs), conditional uses, and dimensional standards (minimum lot area, frontage, setbacks, height). For example, higher density districts allow multi‑family housing outright and have shorter setbacks and higher allowable heights than single‑family zones (see the R‑5 example below for the ordinance language that applies to very‑high density). If you need the exact table for your lot, confirm the specific R‑2 / R‑3 / R‑4 section in the code and consult the map. Not all subsections are repeated here verbatim; confirm parcel‑level standards with the code and Development Services. Not found in retrieved materials in full for R‑2/R‑3/R‑4 text excerpts — verify with the jurisdiction.

R‑5 — Very High‑Density Multi‑Family Residential (§ 10‑5‑12)

Purpose: encourage high‑density multi‑family housing where infrastructure supports it; the city ties R‑5 density to state minimums (default 20 du/acre minimum, up to 24 du/acre). Important rules: minimum parcel area 6,000 sq ft (or 2,000 sq ft lot area per attached single‑family configuration), maximum parcel coverage 60%, front setback 20 ft, maximum building height 40 ft, minimum parcel frontage 60 ft. The section also directs that multi‑family housing that satisfies state affordable‑housing thresholds may be developed by right (no discretionary permit) and requires CEQA review at rezoning time. Site plan review is required for non‑by‑right R‑5 projects.

BP — Business‑Professional (§ 10‑5‑13)

Purpose: professional offices and similar uses. The BP section lists permitted uses, conditional uses, and development standards (minimum lot, coverage, setbacks, height) for office/clinic type development. See § 10‑5‑13 for the full permitted/conditional list and design/landscaping rules.

CBD — Central Business District (§ 10‑5‑14)

Purpose: downtown pedestrian‑oriented commercial and institutional uses. Key standards: no minimum parcel area, maximum building coverage 100%, and parking/uses rules tailored for downtown (some uses are permitted by conditional use). See § 10‑5‑14 for permitted uses (restaurants, retail, hotels, offices), hours restrictions and CBD‑specific development rules.

C — Commercial (General) (§ 10‑5‑15)

Purpose: retail and service activities for the community. Permitted uses include retail, eating/drinking establishments (not fast‑food unless conditional), hotels/motels, professional offices, and certain institutional uses. Dimensional standards: minimum parcel area 6,000 sq ft, maximum building coverage 60%, height 40 ft, FAR 0.6. See § 10‑5‑15 for the full permitted/conditional lists and STR references.

CC — Convenience Commercial (10‑5‑16)

Purpose: neighborhood convenience centers (smaller markets, barber, dry cleaner) with pedestrian/bike focus. Typical standards: minimum parcel area 10,000 sq ft, max coverage 25%, minimum frontage 100 ft, setbacks vary by street classification, max height 30 ft, floor area ratio 0.25. Hours of operation and landscape requirements are spelled out. See § 10‑5‑16.

HWC — Highway Commercial (10‑5‑17)

Purpose: highway‑oriented commercial that serves through traffic; the HWC section lays out allowed uses and standards appropriate for higher‑impact commercial. See § 10‑5‑17 for the full text.

HC — Heavy Commercial (10‑5‑18)

Purpose: wholesale, bulk storage, manufacturing/processing and heavy service uses that would be inappropriate in lighter commercial districts. Permitted uses include gas stations, auto sales/repairs, wholesale and manufacturing as long as emissions/impacts aren’t a nuisance offsite. See § 10‑5‑18 for full conditions and standards.

I — Industrial

Purpose and standards: manufacturing, processing, and industrial support uses; check the I zone text in Chapter 5 for allowed uses, setbacks, and coverage standards. Not reproduced here in full — verify specific I‑zone section in the code and consult Development Services for parcel‑level application. Not found in the retrieved snippets with full numeric table — verify with the jurisdiction.

PF — Public Facilities (10‑5‑20)

Purpose: government and nonprofit public uses (libraries, museums, schools, water/wastewater plants). Standards include minimum lot area 6,000 sq ft, minimum lot width 60 ft, maximum height 45 ft and yard/setback rules (front 10 ft except 20 ft when abutting residential). See § 10‑5‑20.

PD / PDI — Planned Development (Overlay) & Planned Development Industrial (10‑5‑21 / 10‑5‑22)

Purpose: PD (and PDI) provide flexible design options to encourage creative site layout, energy efficiency and integrated open space while maintaining the base density; PD may be used in any zone but the overlay preserves the underlying density. PDI is the industrial‑focused planned development standard and lists permitted/conditional uses and PD procedures. See § 10‑5‑21 (PD) and § 10‑5‑22 (PDI) for preliminary development plan requirements, submittal content and standards.

AO — Airport Overlay (10‑5‑23)

Purpose: airports and their environs are regulated by overlay to ensure safety and noise compatibility. The AO overlay modifies the underlying zone: permitted uses are those of the underlying zone only if consistent with the Placerville ALUCP; ALUC referral and ALUCP consistency review / noise attenuation requirements apply. See § 10‑5‑23 for ALUC/ALUCP coordination and submittal requirements. If your parcel lies in the AO overlay you must comply with ALUCP maps and policies and may be referred to the ALUC.

HO — Housing Opportunity Overlay (10‑5‑24)

Purpose: the HO overlay is a pro‑housing overlay used to implement the housing element; it allows higher densities for affordable housing (minimum 20 du/acre, up to 24 du/acre) and provides incentives (fee deferrals, reduced fees, relaxed process) but requires affordability commitments (e.g., 50% of units affordable to very low/low income per the HO text when those by‑right provisions are used). The HO overlay can be used or the underlying zone — not both — and redevelopment under the base zone generally relinquishes the HO right. CEQA/environmental review, administrative design review, public‑utility, and fire protections are expressly required. See § 10‑5‑24 for the full by‑right rules, density calculations, affordability mix, and incentives.

CBO — Cannabis Business Overlay (10‑5‑25)

Purpose: creates limited areas for commercial cannabis activities consistent with Title 5, Chapter 28 (cannabis business licensing). The CBO section cross‑references the cannabis chapter and restricts where cannabis businesses are allowed. See § 10‑5‑25.

Development rules that apply across zones (quick pointers)

  • Overlay rules supplement or modify underlying rules; consult the official zoning map to see overlays mapped to parcels (§ 10‑2‑4 and § 10‑5‑1).
  • Certain uses may be permitted anywhere but only with a conditional use permit (listed in § 10‑3‑4); conditional use rules and findings are in § 10‑3‑3.
  • Site plan / design review: the code requires site plan review in many cases; R‑5 projects and other specified categories reference § 10‑4‑9 (see R‑5, HO, and PD subsections for when design review is required). Note: here I link the city’s design review guidance—design review rules themselves are in Title 10. See design review rules for submittal details.

Checklist

Applicant items required by Title 10 (common across many zone applications; verify parcel specifics):

  • Confirm parcel's base zone and overlays on the official zoning map (map kept in Development Services) — § 10‑2‑4.
  • Confirm whether the proposal is allowed by right, requires a conditional use permit, or is subject to overlay restrictions (AO, HO, CBO) — see the applicable zone section (e.g., § 10‑5‑8, § 10‑5‑23, § 10‑5‑24).
  • Prepare site plan and required submittals for site plan review or PD plan as applicable (submittal lists appear in PD, HO and other sections; design/site plan review rules referenced in § 10‑4‑9).
  • Calculate dimensional compliance: minimum parcel area, frontage, setbacks, coverage, height, FAR (see the district’s section). Example: R‑1 § 10‑5‑8, R‑5 § 10‑5‑12.
  • Provide parking calculations per the parking chapter § 10‑4‑4 (off‑street parking required for new/expanded uses). See Placerville Parking.
  • If in AO, prepare ALUCP consistency materials and expect ALUC referral (see § 10‑5‑23).
  • If proposing ADU(s), follow the ADU standards and setbacks in § 10‑4‑12 (setbacks: interior side/rear 4 ft, street side 10 ft, front per district with some relaxations). See Placerville ADUs.
  • Confirm utility availability, fire flow and access per HO/PD/subdivision rules (HO § 10‑5‑24, PD § 10‑5‑21).

Risks & Ambiguities

Issue Why it matters What to verify
Overlay mapping (AO / HO / CBO) Overlays change allowed uses, require ALUC reviews (AO) or create by‑right affordable housing (HO); mapped overlay may impose additional restrictions or incentives. Verify whether your parcel is actually mapped with the overlay on the official zoning map in the Development Services office and read § 10‑5‑23, § 10‑5‑24, § 10‑5‑25.
HO by‑right requirements and affordability mixes HO by‑right path requires meeting precise density and affordability commitments (e.g., 50% affordable mix in certain HO by‑right cases). Missing a qualification can convert a by‑right application into a discretionary one. Read § 10‑5‑24 carefully and verify required affordability percentages, CEQA status, and whether you must enter a recorded affordability covenant.
Airport compatibility (AO) / ALUC referral Projects in AO may need ALUC consistency review and additional noise/safety conditions; failing to involve ALUC may delay approval. Confirm ALUCP maps and ALUC referral rules in § 10‑5‑23 and coordinate early with Development Services.
Parcel‑specific setbacks on corner or irregular lots The city gives the development services director discretion to define front/side/rear yards on irregular/corner lots; that can materially change required setbacks. Verify yard designations for your parcel with Development Services; see measurement and encroachment rules (yard exceptions) in the general regulations. § 10‑4‑3 and related yard rules apply.
Parking requirements vs. downtown CBD CBD and other zones may allow reduced or special parking treatment (in‑lieu fees, parking district rules). Not accounting for parking can derail a permit. Check § 10‑4‑4 and the downtown parking district rules and confirm whether an in‑lieu fee is available. See Placerville Parking.
Project specific CEQA / environmental mitigation HO and R‑5 rezones call for CEQA at rezoning — mitigations can add conditions/costs. Confirm CEQA status for the site under § 10‑5‑12 and § 10‑5‑24 and budget for potential mitigation.

Plain‑English Summary

Placerville zoning (Title 10) divides the city into clearly labeled zones (e.g., R‑1, R‑5, CC, PF) and several overlays (notably the HO, AO, and CBO). Each zone lists what you can build and the key numbers (minimum lot, setbacks, height, coverage/FAR). Overlays like the HO and AO change the rules for parcels inside them — so always confirm the official zoning map and the applicable code section (for example § 10‑5‑24 for HO, § 10‑5‑23 for AO) before you design a project.

Frequently asked questions

What can I build on an R‑1 lot in Placerville?

You can build the uses listed as permitted in the R‑1 section (one‑family dwelling, one accessory dwelling unit subject to ADU rules, Jr. ADU, small home occupations, etc.); dimensional standards for R‑1, 6,000 include minimum parcel 6,000 sq ft, front setback 20 ft, height 40 ft and frontage 60 ft — see § 10‑5‑8 for the full permitted list and standards.

What are Placerville setback requirements for single‑family lots?

Setbacks depend on the specific R‑1 variant; for R‑1, 6,000 the ordinance lists front 20 ft, side setbacks are ten percent of parcel width or 10 ft (whichever is less), and rear 15 ft (with exceptions for attached dwellings) — see § 10‑5‑8. For ADU setbacks consult § 10‑4‑12 (interior side and rear 4 ft, street side 10 ft, front per district with limited exceptions).

Do I need design review in Placerville?

Design / site plan review is required for many categories (new commercial construction, multi‑family over certain thresholds, PD, some R‑5 and HO projects). The code references site plan review and administrative design review in several zone sections; check the rules in § 10‑4‑9 and the relevant zone (for example R‑5 and HO reference site plan / administrative design review).

Where do I check whether an AO or HO overlay applies to my parcel?

Overlay applicability is determined by the official zoning map incorporated by reference into Title 10 and kept in the Development Services office; zone boundary rules are in § 10‑2‑4 and the overlay text is in § 10‑5‑23 (AO) and § 10‑5‑24 (HO). Always verify the map with Development Services.

If my site is in the HO overlay, what densities and affordability rules apply?

The HO overlay sets a by‑right minimum density of 20 du/acre (state minimum) and allows up to 24 du/acre as described in § 10‑5‑24; by‑right affordable projects under HO may require at least 50% of units to be affordable to very low and low income households in certain HO by‑right applications (see the affordability mix and by‑right rules in § 10‑5‑24).

Does AO (Airport Overlay) trigger an ALUC review?

Yes. New development and rezones within the AO are subject to ALUCP compatibility review and may be referred to the El Dorado County ALUC; the AO section describes submittal requirements and referral processes — see § 10‑5‑23.

Where are the parking requirements I must meet?

Off‑street parking and loading requirements are in Title 10, Chapter 4 (notably § 10‑4‑4). The code requires parking for new uses and additions that increase demand; downtown parcels may have in‑lieu options. See Placerville Parking for guidance.

Can I put a commercial cannabis business anywhere?

No. Commercial cannabis businesses are only allowed where the Cannabis Business Overlay (CBO, § 10‑5‑25) permits them and where the operator has complied with Title 5 licensing (Chapter 28). Check whether your parcel is in the CBO and whether the specific cannabis use is allowed.

If my lot is irregular or a corner parcel, do setback rules change?

Yes — the development services director has authority to determine front/side/rear yards on corner or irregular parcels and the code provides exceptions for average front yard calculations where adjacent lots are improved. See the yard/dimension rules and encroachments in the general regulations (see discussions in § 10‑4‑3 and the residential zone standards that reference these rules).

What happens if a use isn't listed in my zone’s permitted uses?

If a proposed use is not listed as permitted or as a conditional use (or listed in the commission’s similar uses resolutions), it is unlawful in that zone unless the planning commission grants a variance or rezoning is approved. See § 10‑5‑2 on applicability and the conditional uses and variance chapters for procedures.
