Susanville Zoning, Planning & Building Codes

Last reviewed: July 3, 2026

Overview

Susanville’s land-use rules are codified in Title 17 — Zoning, which establishes the city’s districts, development standards, and permitting rules to implement the general plan and protect public health and welfare § 17.04.010, § 17.04.020 . The code is a conventional Euclidian zoning ordinance (base districts plus combining/overlay districts) with a planned development tool, a design-guidelines requirement for many projects, and a formal use-permit / design-review process for discretionary projects § 17.04.060, § 17.64.060, § 17.112.020 . Read this page as a road‑map to where the actual rules live and what matters for common projects.

How Susanville's code is organized

• The zoning rules live in Title 17 — Zoning; the ordinance is explicitly titled “The Zoning Ordinance of the city of Susanville” § 17.04.020 .
• Definitions are centralized in § 17.08.010 so start there for specialized terms (for example, how the code treats accessory buildings) § 17.08.010 .
• Zone districts are established by ordinance and shown on city zone maps; boundary and interpretation rules appear in the interpretation chapter § 17.04.060, § 17.04.070, § 17.116.020 .
• Site-, yard- and use-specific standards are organized by district chapter (for example R‑1 rules in Chapter 17.12, R‑2 in Chapter 17.16, C‑2 in Chapter 17.36, etc.) — look up the chapter for the district that applies to any parcel. Representative site standards and the design review trigger language are repeated in each district chapter (e.g., § 17.12.060; § 17.16.060; § 17.36.050) .
• Administrative procedures (use permits, variances, map/amendment processing, CEQA review triggers and appeals) are in the procedural chapters (notably § 17.112.020 for use permits and the variance/use-permit rules in § 17.112.060–.080 and related sections) § 17.112.020, § 17.112.060 .

Zoning district families (what the city uses)

The code creates base districts, resource districts, industrial districts, special districts and combining/overlay districts. The list below replicates the exact district names used in the ordinance § 17.04.060 .

Residential

• R‑1 (Single‑family) — standards and setbacks at § 17.12.060; front setback 20 ft, lot coverage 40%, main‑building height 35 ft in the R‑1 rules § 17.12.060 .
• R‑2 (Duplex) — permitted uses include single‑family, duplex and Accessory dwelling units (ADUs); setbacks and lot standards in § 17.16.060 § 17.16.020, § 17.16.060 .
• R‑3 / R‑3(A) (Duplex / Triplex) — medium‑density rules, see Chapter 17.20 § 17.20.010 .
• R‑4 (Multifamily) — up to 20 units/acre in many places; site standards (minimum lot area per unit, lot coverage caps by building type, front/side/rear yard rules and a typical main‑building 35 ft height) at § 17.24.060 § 17.24.010, § 17.24.060 .
• MHP (Mobile home park) — Chapter 17.28 governs parks and lot layout § 17.28.010 .

Commercial / Mixed‑use

• C‑1 (Neighborhood commercial), C‑2 (General / shopping center) and UBD (Uptown Business District) are the main commercial districts with their own building‑size, yard and frontage rules § 17.32.050, § 17.36.050, § 17.40.010 . The UBD explicitly promotes mixed residential and commercial uses § 17.40.010 .

Industrial

• M‑L (Light industrial) and M (General industrial) set permitted industrial uses, outdoor‑storage screening and special performance rules § 17.56.020, § 17.48.010 .

Special / Resource / Planned

• PF (Public facilities), PD (Planned development), U (Unclassified holding zone) and resource districts AR‑1, AE‑20, O‑S are all explicitly listed § 17.04.060, Chapter 17.64 (PD), Chapter 17.68 (U) .
• Combining/overlay districts include B (combining lot size), DR (design review), H (historic preservation), F‑2 (restrictive flood), and a PD combining district — see Chapter 17.84 (DR) and Chapter 17.88 (H) § 17.84.010, § 17.88.010 .

Notes on overlays and design review: the DR overlay is intended to be combined with base districts and requires that site and architectural standards “meet or exceed” the principal district; see the design‑review combining district rules § 17.84.010–.030 and the separate historic preservation combining district § 17.88.010–.020 — consult the city’s design‑review page for practical submittal expectations design review § 17.84.010, § 17.88.010 .

Citywide development standards (high level)

This is a city‑wide orientation — always check the district chapter for precise numeric rules.

Setbacks, height, lot coverage and density

• The code flags per‑district site standards in each chapter (for example R‑1 standards in § 17.12.060, R‑2 in § 17.16.060, R‑4 in § 17.24.060, C‑2 in § 17.36.050) — typical front setbacks are 10–20 ft depending on district, side setbacks 5–15 ft, rear setbacks 10–15 ft, and main‑building heights commonly 35 ft in residential districts and up to 40 ft in some commercial districts § 17.12.060, § 17.16.060, § 17.24.060, § 17.36.050 .
• Lot coverage caps are explicit in district chapters (e.g., 40% typical for single‑family in R‑1/R‑2; R‑4 uses tiered coverage: triplex 40%, fourplex 50%, five+ units 60%) § 17.12.060, § 17.16.060, § 17.24.060 . Note: floor‑area‑ratio (FAR) is not consistently used as a primary control in the local chapters returned; verify with the specific chapter for a parcel (search the district chapter for any FAR provisions) Not found in retrieved materials .

Parking, landscaping, lighting and other site controls

• Off‑street parking standards live in § 17.100.010–.160; many district chapters refer to these sections and add covered‑parking minimums for new single‑family dwellings (two covered spaces, each 10 ft × 20 ft) § 17.100.010–.160; § 17.12.060(D); § 17.16.060(G) — see the city parking rules for stall counts and special commercial provisions parking § 17.100.010–.160, § 17.12.060 .
• Landscaping, lighting and zone‑wall (screening) standards are centralized in Chapter 17.96 and cross‑referenced by districts § 17.96.040, § 17.96.050, § 17.96.060 .
• Sign rules are in Chapter 17.128 and are referenced in district chapters § 17.128; see C‑2 & R‑4 references .

Design and discretionary review

• Architectural and site‑plan review is a consistent requirement for all projects that need a use permit or when district chapters call it out; the code repeatedly requires elevations/site plans and applies the City of Susanville Design Guidelines (adopted July 17, 2002) as part of review § 17.64.060, § 17.24.060(H), § 17.12.060(F) — for practical submittal expectations see the city design‑review page design review § 17.64.060 .
• Use permits (conditional and planned development use permits) are approved through the planning commission with public hearings, CEQA review as required, findings, conditions, and possible appeals; the rules and process are codified in § 17.112.020 and related sections § 17.112.020, § 17.112.060 .

Specific plan, PD and overlays

• Planned Development (PD) projects require a development plan and a PD use permit; the PD ordinance or approved PD plan establishes allowed uses, and default to the underlying zone standards where PD specifics are silent § 17.64.030–.040 .
• The code’s combining/overlay districts (DR, H, F‑2, etc.) modify or add standards where applied — e.g., the DR overlay requires that combined district standards “meet or exceed” the principal district and that use permits show compatibility with DR purposes § 17.84.030–.040 . See the overlay summary on the overlays page overlay districts § 17.84.010 .

Building permits & review (typical project paths)

• Ministerial projects (most building permits that conform to zoning, building and site standards) proceed via the community development/building department once the zoning clearance and building plans are complete; district chapters make clear that building permits that require a use permit or variance may not be issued until the discretionary approval and any appeal period are resolved § 17.112.020(I), § 17.112.060(H) .
• Discretionary approvals: apply for a use permit (forms and fee per § 17.112.020(A–B)); the planning commission holds the hearing, makes findings, and an approved resolution constitutes the permit. No building permit for a project requiring a use permit will be issued until the appeal period or appeal resolution has passed § 17.112.020(A–I) .
• Variances follow a similar public‑hearing path and are strictly limited — variances cannot authorize uses not allowed by the zone § 17.112.050 .
• Architectural/site drawings and design‑guidelines compliance are repeatedly required as part of either building‑permit completeness checks or use‑permit submittals § 17.64.060, § 17.24.060(H) .

State housing law in Susanville — how it interacts with the local code

• ADUs / second units: Susanville explicitly lists accessory dwelling units (attached, detached, and junior ADUs) as permitted uses in multiple residential districts (for example § 17.16.020(B) for R‑2 and § 17.24.020(H) for R‑4) and has a dedicated second‑unit section with numeric size/parking/submittal rules (§ 17.104.050) — consult the local ADU chapter and the city ADU guidance ADUs § 17.16.020, § 17.24.020, § 17.104.050 .
  • The second‑unit rules limit detached unit size (1,200 sq ft for detached second unit in § 17.104.050(E)), set parking rules (one space per bedroom not to exceed two for a second unit), require owner‑occupancy absent a use permit in some cases, and require building‑permit and site‑plan review § 17.104.050 .
  • Note: state ADU law preempts certain local restrictions; for statewide rules and recent ADU changes consult the California ADU law summary California ADU law and the state building code guidance California Building Standards Code. The local code shows ADUs are an expressly permitted use in typical residential zones but does not restate all state preemptions (see local ADU sections above; verify with state ADU law) § 17.104.050; Not all state preemption details present in retrieved local materials .
• Density bonus: the R‑1 site‑standard language explicitly references “the residential density permitted by the general plan, including any permitted density bonus,” which indicates the code recognizes density‑bonus adjustments to allowed density § 17.12.060(A) . For specific bonus procedures, consult the local planning department and state density‑bonus statute.
• SB 9 / ministerial duplex lot splits and ministerial approvals: the code’s discretionary permit structure (use permits, variances, map amendment process) is fully present, but I did not find an explicit local SB 9 implementation chapter in the retrieved zoning text; therefore the local approach to SB 9 ministerial lot splits or urban lot splits is Not found in retrieved materials — verify with the community development department .
• Rent control / rental‑price regulation: the zoning code does not set rent‑control rules. No local rent‑control provisions were found in the retrieved zoning chapters; consult municipal code chapters outside Title 17 or county/state statutes for rent regulation Not found in retrieved materials — verify with city clerk or municipal code .

Practical note: state law (ADU rules, building‑code standards in Title 24, density bonus statutes) often constrain what a city may require; always cross‑check a proposed ADU or a ministerial lot split with state ADU and housing law guidance California housing laws and the California Building Standards Code California Building Standards Code before assuming local rules control every element.

Information Gaps / Things to confirm with the city

• The local code text returned does not include a discrete, up‑to‑date SB 9 implementation section — confirm how the city processes SB 9 lot splits and ministerial duplex approvals (if any) with the Community Development Department Not found in retrieved materials .
• If you need explicit numeric FAR limits for non‑residential projects, I did not find a citywide FAR table in the returned materials; check the district chapter for project‑specific FAR language or ask the planner Not found in retrieved materials .
• For up‑to‑date administrative forms, local checklists (ADU checklist, building‑permit checklist), fees and process timelines use the city’s permitting counter materials; procedural detail in the code sets the rules but not the submittal packets See community development department — code references cited above .
