Mount Shasta Zoning, Planning & Building Codes

Last reviewed: July 4, 2026

Overview

This page summarizes how land use and development are regulated inside the City of Mount Shasta under the Mount Shasta Municipal Code (the City’s zoning title). It names the actual base zones and where to find the rules, explains how citywide standards (setbacks, height, lot coverage, parking) are organized, and orients you to discretionary review paths, specific-plan / planned-development rules, and how limited elements of state housing law are referenced locally. For the official zoning map and to see parcel designations, start with the city’s zoning pages and land-use menu: Mount Shasta Zoning and Mount Shasta Land Use.

How Mount Shasta's code is organized

• The municipal zoning code is codified in Title 18 of the Mount Shasta Municipal Code; base zoning districts are listed at § 18.12.020 .
• District regulations and the detailed tabular site standards (setbacks, lot size, height, permitted/conditional/accessory uses) are collected in Chapter 18.16 (District Regulations) — the primary place to read the numeric limits for each zone is § 18.16.020 .
• Procedural and approval rules (who decides what) are summarized in the City’s approval-authority tables and development-agreement rules in Chapter 18.36 (see the approval table) and the local CEQA procedures are in Chapter 18.95 .
• Submittal and site-plan / permit-content requirements for building/permitting are in Chapter 18.31 (site-plan contents and documentation) — see § 18.31.030–18.31.040 .
• Objective design and citywide development rules (including parking, landscaping, and other objective standards) are in the Objective Design Standards chapter; see the city’s Development Standards and the local cross-reference to Chapter 18.50 (e.g., parking cross-references) .

Zoning district families

The code establishes the following base zone families (listed exactly in the code): Resource Lands (R-L), Unclassified (U), Low Density Residential, 10,000 Minimum (R1/B1), Low Density Residential (R-1), Low Density Residential Urban (R-1‑U), Medium Density Residential (R-2), High Density Residential (R-3), Downtown Commercial (C-1), General Commercial (C-2), Employment Center (E‑C), Planned Development (P‑D), Public (P), and Open Space (OS) — see § 18.12.020 and the district regulation tables collected under § 18.16.020 .

Practical highlights from the district tables (all drawn from the tables in § 18.16.020):

• R1/B1 (Low Density, 10,000 min): front setback 25 ft, rear 10 ft, side 10 ft, max height 35 ft, max lot coverage 45% (Table 3) — see § 18.16.020 (Table 3) .
• R‑1 (Low Density): front setback 20 ft, rear 10 ft, combined side yards 10 ft (min one side 4 ft), max height 35 ft, max lot coverage 50% (Table 4) — see § 18.16.020 (Table 4) .
• R‑2 (Medium Density): maximum density 10 units/acre, front setback 10 ft (garage-facing street 20 ft), minimum parcel sizes vary by unit type — see § 18.16.020 (Table 6) .
• R‑3 (High Density): front setback generally 20 ft (10 ft with alley parking), max building height 45 ft, maximum lot coverage 65% for multi‑family (Table 7) — see § 18.16.020 (Table 7) .
• C‑1 / C‑2 / E‑C (commercial and employment) have their own permitted and conditional-use lists and follow similar siting tables in § 18.16.020 .
• Planned Development (P‑D) is used where a project seeks site‑specific deviations (density, setbacks, heights) through a planned-development plan; minimum parcel size is stated and the P‑D allows the Council to approve deviations upon specified findings — see § 18.16.020 (P‑D / Tables 11–11.7) .

Citywide development standards (how to find the rules)

• Where to look: most zone-specific numeric standards live in § 18.16.020 (the zone tables) and the city’s Objective Design Standards and development-standards chapter provides cross-cutting rules on setbacks, building massing, parking, landscaping, and screening (see the city’s Development Standards and Landscaping and Screening pages and Chapter 18.50 cross‑references) .
• Setbacks, heights and lot coverage: the numeric front/rear/side setbacks, maximum heights, and lot-coverage caps are set in each zone table; see § 18.16.020 for the R1/B1, R‑1, R‑2 and R‑3 tables cited above .
• Floor area ratio (FAR): the code uses density and lot‑coverage metrics in the zone tables rather than a single citywide numeric FAR in the excerpts reviewed; see each zone’s table in § 18.16.020 for the controlling figures .
• Parking: parking minimums and layout standards are enforced via the Objective Design Standards; where a use-specific minimum appears the code cross‑references MSMC 18.50.030 for parking layout and stall rules (tiny-home provisions, for example, require 1 parking space per tiny home/unit and refer to § 18.50.030 for layout) — see § 18.18.060(A) and the cross-reference to § 18.50.030 .
• Landscaping, screening, and signage: objective standards and screening requirements are implemented through Chapter 18.50 and related site‑plan/landscape provisions (see the Development Standards and Landscaping and Screening menus for how these are presented locally) .

Design review, discretionary approvals, and appeals

• Who decides: the code’s approval‑authority matrix shows which decisions are ministerial or discretionary and who is the recommending vs. final decision maker. The matrix (Table 18.36.1) lists items such as Administrative Permit, Zoning Clearance/Plan Check (planner), Variance and Conditional Use Permit (Planning Commission final after planner recommendation), and Design Review (planner recommends; Planning Commission acts as final) — see the approval table collected under Chapter 18.36 (Table 18.36.1 / approval authority) and related Planning Commission rules § 18.36.060–18.36.080 .
• Design standards and objective design review: certain objective design provisions are mandatory (chapter 18.50); tiny-home standards explicitly require compliance with Chapter 18.50 as part of ministerial/administrative review when applicable — see § 18.18.040 and the cross reference to Chapter 18.50 .
• Appeals: appeal procedures follow Chapter 18.32; appeals from planner actions go to the Planning Commission, and appeals from Planning Commission go to the City Council — see § 18.32.020–18.32.030 .

Specific plans & overlays

• Specific plans and planned-development processes: Mount Shasta’s code includes a Planned Development (P‑D) district and establishes findings and site‑specific standards for a P‑D that can supersede base-zone standards when the required findings are made; the planned-development rules and required findings are in the P‑D language in § 18.16.020 (P‑D) (see the P‑D site-development standards and required findings) .
• Specific plans (and their approval path) are treated as higher‑level legislative/discretionary items in the approval matrix and involve Planning Commission recommendation and City Council final action under Chapter 18.36 (see Table 18.36.1) .
• Overlay districts and combining zones: Mount Shasta uses the P‑D combining zone and other localized overlays via the zoning map and text; where a parcel is within a combining zone the underlying base‑zone uses generally remain permitted unless the combining-zone text specifies otherwise — see the Planned Development text in § 18.16.020 .

Building permits & review — step‑by‑step orientation

1. Pre‑application / research: confirm the parcel’s zone on the official zoning map (City Planner maintains the official zoning map; see § 18.16.060) .
2. Determine required approvals: check § 18.16.020 for zone‑specific allowed/conditional uses and site standards; check the approval table (Table 18.36.1) to see whether the application will be ministerial or discretionary (planner, Planning Commission, or City Council) — see § 18.16.020 and § 18.36.060–18.36.080 .
3. Prepare forms and site plans: building‑permit applications and site plans must include the items listed in § 18.31.030 (single‑family) or § 18.31.040 (multi‑family/commercial) — these sections list required plan content (property lines, setbacks, parking, landscaping, drainage, etc.) .
4. Staff review / interdepartmental review: the Planner and relevant departments perform plan check and issue zoning clearance or route discretionary items for public hearing per Chapter 18.36 and the local CEQA rules in Chapter 18.95 .
5. Final permits and building code compliance: approved land‑use entitlements are followed by building permits enforced to the California Building Standards (local code references to the California Residential Code appear in the tiny‑home standards) — see the tiny‑home requirement to meet the 2022 California Residential Code and ANSI standards in § 18.18.020 .

State housing law in Mount Shasta

The Mount Shasta code references, and in some instances implements, state housing rules — but the local code is not a substitute for the state statutes. Below are the practical intersections found in the retrieved materials.

• ADUs / accessory units: the code does expressly treat some alternative dwelling types. For example, the Tiny Homes on Wheels chapter allows a THOW to be reviewed as a primary single‑family dwelling or as an accessory dwelling unit when configured and reviewed as such — see § 18.18.030 (regulatory authority) . The code does not show in the retrieved material a standalone, comprehensive ADU chapter; check with the Planning Department for an ADU-specific section or administrative checklist (verify with the jurisdiction). (First mention link within prose: Mount Shasta ADUs; for state ADU rules see California ADU law.)
• Density bonus: the local tiny‑home provisions explicitly reference the state density‑bonus statute (Government Code § 65915) as a possible modification mechanism for tiny‑home villages — see the tiny‑home provisions that reference Government Code § 65915 in the tiny‑home chapter (Chapter 18.18) .
• SB 9 / lot splits and ministerial duplex approval: no explicit SB 9 (urban lot split / ministerial two‑unit) language was found in the retrieved materials. That absence in the retrieved text does not confirm the City’s current practice; verify with the Planning Department and current municipal ordinances. (Not found in retrieved materials.)
• Rent control / eviction protections: no local rent‑control or local rent‑stabilization ordinance appears in the retrieved municipal zoning excerpts; verify at the City or County level if you need definitive confirmation. (Not found in retrieved materials.)
• Local alignment with state ADU and housing law: where the city references state law (e.g., Government Code § 65915 for density bonus, and the California Residential Code for building standards), those references are explicit (see § 18.18.020 for building‑code references and the tiny‑home density bonus cross‑reference) .

Special topics called out in the code

• Short‑term rentals: specifically prohibited in the R‑1 zone — see § 18.16.040 (Short‑term rentals prohibited in R‑1 zone) .
• Cannabis land uses: the code contains a cannabis chapter with development standards and licensing cross‑references; commercial cannabis uses must meet the standards of the zoning district and the permitting rules in Chapter 18.91 (see § 18.91.060–18.91.070) .
• Tiny homes & THOW: detailed objective standards (size, insulation, connection to utilities, parking, skirting) and where they are permitted are collected in Chapter 18.18 (see § 18.18.010–18.18.070) .

(First mention link within prose: Mount Shasta Historic Preservation — if your property is historic, check the local historic‑preservation chapter for overlays; not all results here covered that chapter directly.)

Information Gaps (what I could not confirm in the retrieved files)

• A dedicated, full ADU chapter (many cities have one; I did not find a complete ADU chapter in the retrieved text — only THOW references to ADU review) — verify with the Planning Department or the full municipal code. (Not found in retrieved materials.)
• Any explicit SB 9‑implementing ordinance or local objective standards for urban lot splits and ministerial duplexes — no explicit SB 9 text was found in the retrieved excerpts. (Not found in retrieved materials.)
• Exact text of Chapter 18.50 (Objective Design Standards) beyond cross‑references — the tiny‑home rules reference 18.50, but the full design‑standards text was not included in the snippets I reviewed. (Partial in retrieved materials; verify full chapter.)
• Current fee schedule, development‑impact fees, and the official, up‑to‑date digital zoning map — the code says the City Planner maintains the official map (§ 18.16.060) but the map itself and current fee tables were not in the retrieved excerpts .
