Dunsmuir Zoning, Planning & Building Codes

Last reviewed: July 3, 2026

Overview

This page orients you to the City of Dunsmuir’s local land‑use law: the City’s zoning ordinance is codified as Title 17 — ZONING (the City of Dunsmuir Zoning Code) and establishes a zoning map, base districts, combining/overlay districts, and the permit procedures used to build and change uses in the city § 17.04.020 . The Title was comprehensively updated by Ordinance No. 575 (effective June 29, 2023) and the code is organized into: general provisions and definitions, district chapters that carry the permitted uses and the numerical development standards, procedural chapters for permits/appeals, plus specialized chapters (e.g., objective design standards, historic preservation, density bonus) § 17.04.010; § 17.12.010 .

How Dunsmuir's code is organized

• Title name and adoption: the ordinance identifies itself as The City of Dunsmuir Zoning Code § 17.04.020 .
• District list and map: the code lists base zoning districts and combining districts and makes the City of Dunsmuir Zoning Map part of Title 17; the map is on file with the city clerk § 17.12.010; § 17.12.020 .
• Where rules live: use lists and district-specific development standards are carried in each district chapter (for example, low‑, medium‑, and high‑density residential chapters each set dwelling/acre, height, setbacks, lot coverage, and cross‑reference off‑street parking) § 17.16.020; § 17.20.060; § 17.24.060 . Procedural rules for discretionary permits (use permits, variances) and appeals appear in the permit chapters § 17.88.040–.060 . Objective design rules used for streamlined, ministerial review are in Chapter 17.132 § 17.132.010–.030 .

Zoning district families (what they are, where to find them)

The ordinance defines the base districts by chapter and purpose (all citations are to each chapter’s purpose/preamble):

• R-1 — Low Density Residential (Chapter 17.16) — for low‑density single‑family and similar uses § 17.16.010 .
• R-2 — Medium Density Residential (Chapter 17.20) — allows duplexes and medium‑density housing § 17.20.010 .
• R-3 — High Density Residential (Chapter 17.24) — for multifamily and higher density residential § 17.24.010 .
• MU-1 — Residential Mixed‑Use (Chapter 17.28) — small‑scale mixed uses where residential predominates § 17.28.010 .
• MU-2 — Neighborhood Mixed‑Use (Chapter 17.32) — higher‑intensity mixed uses along primary roadways § 17.32.010 .
• MU-3 — Central Mixed‑Use (Chapter 17.36) — central/more intensive mixed‑use locations (see district list) § 17.12.010; § 17.36.060 .
• T‑C — Town Center (Chapter 17.40) — the historic commercial core; the chapter explicitly cites pedestrian orientation and limited off‑street parking § 17.40.010 .
• S‑C — Service Commercial (Chapter 17.44) and L‑M — Light Manufacturing (Chapter 17.48) — heavier commercial/industrial uses § 17.44.010; § 17.48.010 .
• M — Manufacturing (chapter listed as a base district) and O‑S — Open Space (Chapter 17.56) — resource and open space areas § 17.12.010; § 17.56.010 .
• P‑F — Public Facilities (Chapter 17.60) and P‑D — Planned Development (Chapter 17.64) — public uses and flexible planned development regimes § 17.60.010; § 17.64.010 .

Combining (overlay) districts: the code establishes a Historic (H) combining district and other combining rules — see the district list § 17.12.010 and the Historic Preservation chapter 17.68 for how the overlay works § 17.12.010; § 17.68.010 . (See the Dunsmuir Overlay Districts page for quick links.)

Citywide development standards — how they work (setbacks, height, FAR/coverage, parking)

• The code sets numeric standards inside each zoning chapter: dwelling units/acre (density), maximum building height, maximum lot coverage, and minimum setbacks appear in the development‑standards subsections of each district chapter (examples: R‑1: § 17.16.060; R‑2: § 17.20.060; R‑3: § 17.24.060; T‑C: § 17.40.060) .
  • Example figures you will see in the code: R‑1 maximum height 30 ft; R‑1 lot coverage 40% § 17.16.060 . R‑2 and R‑3 chapters likewise specify dwelling units/acre, 30–35 ft heights, setback dimensions in their development‑standards subsections § 17.20.060; § 17.24.060 . Town Center (T‑C) explicitly allows up to 70 ft in height and up to 100% lot coverage with minimal setbacks because it is the downtown mixed‑use core § 17.40.060 .
• Parking is not a single citywide table in the district chapters; instead each district’s minimum‑parking lines refer to the Off‑Street Parking chapter: "Minimum parking: As specified in Chapter 17.76 (Off‑Street Parking)" (see, e.g., § 17.16.060(H); § 17.20.060(H)) — consult the Dunsmuir Parking page and Chapter 17.76 for the matrix and exceptions § 17.16.060; § 17.20.060 .
• Building code coordination: minimum distances between buildings and some construction standards reference the California Building Code / Title 24 — the district chapters repeatedly use the phrase "As required by California Building Code" for inter‑building separation (e.g., § 17.16.060(G); § 17.24.060(G)) . (See the California Building Standards Code link for the state code.)

For design controls in residential/mixed projects, Dunsmuir has an Objective Design Standards chapter that supplements district standards and is mandatory for qualifying multifamily or mixed projects that request streamlined ministerial approval under state law § 17.132.010–.030 .

Specific plans & overlays

• Historic preservation overlay: Dunsmuir establishes the Historic (H) combining district and a Dunsmuir Historic Commercial District with an explicit review path for historic site alterations, a historic‑delegate review step, and required planning‑commission review when impacts are likely § 17.12.010; Chapter 17.68; § 17.68.110 . The code names the four‑block core and includes a figure and a historic review procedure with permit submittal requirements § 17.68.200; § 17.68.110 . (See the Dunsmuir Historic Preservation and Overlay Districts pages.)
• Planned developments: P‑D chapter provides a mechanism to create project‑level standards that can vary from base district rules when justified by an overall development plan; the P‑D process requires submittal of a sitewide plan, densities, and custom development standards § 17.64.010–.070 .
• There are targeted chapters for specialized functions (wireless facilities Chapter 17.120; signs Chapter 17.80; short‑term rentals Chapter 17.100; bed & breakfasts Chapter 17.104) each with its own review triggers and permit/appeal rules § 17.120.030; § 17.80.150; § 17.100.050; § 17.104.030 .

Building permits & review — the typical path

1. Determine applicable zoning and required entitlement(s): consult the district chapter for permitted uses and the code’s procedure chapters: administrative/ministerial actions (defined), conditional use permits, variances, planned development, and site plan requirements § 17.08.070; § 17.88.040; § 17.64.070; § 17.92.020 .
2. Discretionary review: conditional use permits and variances are processed with application completeness checks, public hearing windows, and required findings spelled out (planning commission action and appeal windows are specified) § 17.88.040–.060 .
3. Objective design / ministerial path: qualifying multifamily/mixed projects that meet Government Code triggers may pursue ministerial, objective design review under Chapter 17.132; the city manager or designee is the approving authority for objective standard compliance § 17.132.020–.030 .
4. Building permits: once entitlement(s) are approved, applicants must obtain building permits and build in accordance with approved plans; several chapters explicitly require a building permit after discretionary approvals (example: § 17.120.110(C) for wireless facilities and general cross‑references in permit chapters) .
5. Appeals and timelines: the code sets deadlines for completeness checks and hearing and decision windows (e.g., 30 days for completeness determination, public hearing within 45 days after completeness, planning commission decision timelines) § 17.88.040–.050; § 17.88.060(C) .

State housing law in Dunsmuir (ADUs, JADUs, density bonus, SB9, rent rules)

Summary: Dunsmuir’s Title 17 both implements local numeric standards and incorporates state‑required processes where applicable. Below are the major interactions and the local citations that govern them.

• ADUs / JADUs: Dunsmuir explicitly allows Accessory Dwelling Units (ADUs) and Junior ADUs (JADUs) across residential and mixed‑use districts by cross‑reference in district accessory‑use lists and a dedicated ADU chapter (referenced in district chapters and in the code’s ADU chapter). For example, R‑1, R‑2, R‑3, MU‑1, MU‑2 and other chapters permit accessory dwelling units and explicitly reference Chapter 17.116 (Accessory Dwelling Units) (see district accessory uses: § 17.16.030; § 17.20.030; § 17.24.030; § 17.28.030) . The code contains JADU timing and processing requirements (e.g., ministerial issuance within 60 days for qualifying JADUs) § 17.116. (JADU timing)* . See the Dunsmuir ADUs page and State ADU law for how state minimums (Gov. Code ADU provisions) interact with the local chapter. (For the state law baseline, refer to California ADU law.)

• Density bonus and affordable‑housing incentives: Dunsmuir implements density bonus provisions in Chapter 17.128; the chapter tracks Government Code requirements, provides for regulatory agreements, waivers/ reductions, and procedural rules for negotiating incentives and concessions § 17.128.010–.080 . The city requires a regulatory agreement before final occupancy where a density bonus is used § 17.128.080 .

• Objective design‑driven streamlining: the Objective Design Standards chapter was drafted to implement the streamlined ministerial approval path authorized by state law for qualifying multifamily projects (Gov. Code 65913.4 references), and the chapter applies to R‑ and MU‑districts and T‑C where the project meets state triggers § 17.132.020 .

• SB 9 (ministerial two‑unit/lot split): the Dunsmuir Zoning Code does not include a chapter that explicitly cites "SB 9" by name in the retrieved materials; local practice for SB 9 compliance will be governed by state law and the City’s map/ministerial standards — where local objective standards apply, Chapter 17.132 identifies objective design standards for streamlined processing (but I did not find a local SB 9‑specific chapter in the materials provided). Recommendation: verify current SB 9 implementation details with the planning department (Not found in retrieved materials — verify with the jurisdiction) (verify: no explicit SB 9 wording located in the retrieved Title 17 excerpts) .

• Rent control / local rent limits: I did not find an ordinance imposing rent control or local rent stabilization in the retrieved zoning chapters (Title 17 addresses uses, design, and development standards, not rent‑setting). If Dunsmuir had a rent‑control chapter it would normally appear elsewhere in the municipal code; not found in the Title 17 excerpts provided (Verify with the jurisdiction) (Not found in retrieved materials) .

Practical notes: ADU/JADU permit timing references and some JADU ministerial timing are in the ADU chapter § 17.116; density bonus rules, waivers, and regulatory agreements are in Chapter 17.128 § 17.116; § 17.128.060–.080 . For state baseline rules see the California housing laws and California ADU law links.

Information gaps / what to verify with the city

• I did not find any explicit SB 9 (statutory duplex/lot split) procedural chapter or explicit SB 9 labeling in the supplied Title 17 excerpts — confirm current SB 9 implementation with Dunsmuir planning staff (Not found in retrieved materials) .
• I did not find any local rent‑control / tenant protection chapter in the Title 17 excerpts; verify in the broader municipal code if you need tenant‑protection information (Not found in retrieved materials) .
• For the complete parking rate table and parking exceptions tied to transit or historic districts, consult Chapter 17.76 (Off‑Street Parking) and Chapter 17.132 parking exceptions for streamlined projects § 17.76; § 17.132.040 .
