Marana City Zoning Code

CHAPTER 17

4. ZONING

17-4-1 Zone districts and zoning groups established

A.   The zones and zoning groups listed in table 1 (zone districts and zoning groups summary) are established by this section.
B.   Table 1 also shows the consolidation of certain residential zoning districts into zoning groups as of the effective date of this chapter. These zoning groups combine zones that allow the same uses in the use matrix table (table 2) and the conditions per use table (table 3). In some cases, a zoning group label is used for ease of reference in table headings and cross-references (for example, "ER" in place of "R-36").
C.   Official zone map. The location and boundaries of each of the zones are shown on the official zone map of the town, and the map is a part of this code. Whenever amendments or changes are made in zone boundaries, the amendments or changes must be made by ordinance and recorded on the official zone map. The official zone map data layer maintained by and located in the office of the technology services department is the final authority in determining current zoning status.
D.   Zone districts and zoning groups summary table. The following table shows the town's zone districts and zoning groups.

17-4-2 Use matrix

A.   Table 2 (use matrix) identifies the permissiveness of uses in all residential zoning groups and zoning districts other than the mixed-use districts and the SP zone. (Uses for the mixed-use districts are set forth in the mixed-use zoning district use matrix found at table 8.)
B.   The notations in table 2 have the following meanings:
   1.   "P" means the use is permitted subject to design standards.
   2.   "A" means the use is permitted as an accessory use located on the same lot with a permitted use.
   3.   "C" means the use is allowed upon approval of a conditional use permit (see section 17-3-2).
   4.   "U" means the use is allowed upon meeting the conditions set forth in table 3 below.
   5.   "T" means the use is allowed upon approval of a temporary use permit (see section 17-3-3).
   6.   "X" means the use is prohibited.
C.   Uses not mentioned.
   1.   General presumption. Uses not listed shall be presumed to be prohibited, unless the planning manager determines that the use is materially similar to a listed use.
   2.   Planning manager determination. If a use is not listed in table 2 and is not otherwise prohibited by law, the planning manager shall determine whether the use is materially similar to a use listed in table 2, using as a guide the type of business, industry, or governmental activity as classified and defined by the two-digit sector number of the most recently published north American industry classification system (NAICS) as established by the United States census bureau.
   3.   Materially similar uses. If the planning manager finds that the use is materially similar, the regulations governing that use shall apply to the use not listed and the planning manager's decision shall be filed in the office of the town clerk.
   4.   Not materially similar uses. If the planning manager determines that a materially similar use does not exist, the planning manager may consider submitting an amendment to this section to establish a specific listing for the use in question by legislative action of the town council upon recommendation by the planning commission.

A.   The R-180, R-144, R-80, R-36, R-16, R-10, R-8, R-7, R-6, R-5, R-4, and R-3 residential zones consist primarily of single-family homes, with one dwelling and accessory buildings on an individual lot.
B.   The following development standards apply in the R-180, R-144, R-80, R-36, R-16, R-10, R-8, R-7, R-6, R-5, R-4, and R-3 zones:
   1.   Minimum lot sizes for each zone are determined by the number following the dash multiplied by one thousand square feet. For example, the minimum lot size of the R-180 zoning district is 180,000 square feet.
   2.   Properties are regulated based on their primary use as set forth in the use matrix set forth in section 17-4-2.
   3.   Only one primary use is permitted.
   4.   No accessory buildings may be located within the minimum front setback.
   5.   Lot widths and depths.
      a.   Each lot must have a width-to-depth ratio of between 3.0 and 0.33. Therefore, the average depth of the lot must be at least one-third its average width, and the average width of the lot must be at least one-third its average depth.
      b.   When the ratio set forth in the preceding paragraph provides a lot width or depth less than the minimum lot widths and depths set forth in table 4 (development standards per residential zone), the minimum lot widths and depths set forth in table 4 apply.
   6.   Utilities. All utilities must be undergrounded.
   7.   Table 4 (development standards per residential zone) establishes the site development standards of the residential zones (with the column headings deleting the "R-" portions of the zone designations, and where "B" signifies that the item is governed by minimum building code requirements only):

17-4-9 Mixed-use zoning districts

A.   General. The mixed-use zoning districts are the BU, DO, DT, and DN zones. Properties in mixed-use zoning districts are regulated primarily on the physical form, intensity, character, and size of buildings and uses. Use restrictions in the mixed-use zoning districts are found in the use matrix set forth in table 8 below.
B.   Purpose. The mixed-use zoning districts promote walkable, compact, downtown and neighborhood development. The zones will vary the intensity of land use, variety of land uses, scale and size of buildings, and other factors according to the context.
   1.   The BU zone is implemented through a blended-use plan, approved with the rezoning to BU, comprised of a combination of the three intensities described below and regulated by section 17-4-11.
      a.   Low intensity. Consists of single-family residential areas, with some mix of uses, home occupations, and accessory buildings.
      b.   Medium intensity. Consists of a mix of uses but is primarily blended density residential. It contains a wide range of building types-houses, courtyard housing, townhouses, duplexes, triplexes, small apartment buildings, and live-work units.
      c.   High intensity. Consists of higher density mixed-use buildings that accommodate retail, offices, institutions, and apartments or condominiums.
   2.   The DT and DN zones are implemented through a downtown implementation plan, submitted by one or more owners of land located in the DO district. Until submission and approval of a downtown implementation plan, the underlying zoning entitlements remain in place. Upon town approval of a downtown implementation plan, the underlying zoning entitlements are replaced with the zoning entitlements set forth in the DT and DN zones.
C.   Use. Mixed-use districts are subject to the requirements of table 8 below, where the notations have the following meanings:
   1.   "P" means the use is permitted subject to design standards.
   2.   "A" means the use is permitted as an accessory use located on the same lot with a permitted use.
   3.   "C" means the use is allowed upon approval of a conditional use permit (see section 17-3-2).
   4.   "U" means the use is allowed upon meeting the conditions set forth in table 9 below.
   5.   "T" means the use is allowed upon approval of a temporary use permit (see section 17-3-3).
   6.   "X" means the use is prohibited.
D.   Uses not mentioned.
   1.   General presumption. Uses not listed in Table 8 and not otherwise prohibited by law shall be presumed to be permitted subject to the conditions and restrictions that apply to the most similar use, as determined by the planning manager. A use shall be prohibited only if the planning manager determines that the use is not similar to any listed use.
   2.   Planning manager determination. In making the determination required by paragraph 17-4-9 D. 1 above, the planning manager shall use as a guide the most recently published north American industry classification system as established by the United States census bureau.
   3.   Notice of determination. The planning manager's determination under paragraph 17-4-9 D. 1 above shall be filed in the office of the town clerk, with copies provided to the council and manager.
   4.   Ratification or modification. The planning manager's determination may be ratified or modified by legislative action of the town council upon recommendation by the planning commission.
   5.   No similar uses. If the planning manager determines that a similar use does not exist, the planning manager may submit an amendment to this section to establish a specific listing for the use in question by legislative action of the town council upon recommendation by the planning commission.

Tables 8 and 9 of section 17-4-9 were amended by Ordinance 2025.023

17-4-10 Mixed-use streets

The requirements of this section, rather than the town's subdivision street standards manual, apply within the BU, DN, and DT zones.
A.   Centerlines of offset thoroughfares entering onto a collector or arterial must be at least 300 feet apart.
B.   Streets must connect to other streets, forming a network. The planning manager is authorized to permit a deviation to this requirement, thereby allowing a dead-end street terminating in a cul-de-sac, consistent with the following requirements:
   1.   The planning manager, in consultation with the town engineer, makes one or more of the following determinations:
      a.   The physical terrain will make connection to other streets cost-prohibitive or unsafe.
      b.   Existing development physically blocks connection to other streets.
      c.   Access restrictions or standard traffic engineering considerations make connection impossible or unsafe.
   2.   Connectivity for bicycles and pedestrians should be created and maintained whenever possible, even when there is no vehicular connectivity.
   3.   No cul-de-sac may exceed the greater of 300 feet to the center of the bulb or one-half block in length.
C.   Block standards.
   1.   Blocks consist of lots surrounded by streets.
      a.   Lengths of block faces may not exceed the maximum length of a block face, measured along lot lines, per table 13, except the planning manager may increase the maximum length by up to 10% to accommodate specific site conditions.

      b.   Where two or more zones or intensities occur on the same block face, the block face length may not exceed the shortest required length.
   2.   The planning manager may exempt blocks adjacent to undeveloped land, areas unsuitable for development, or pre-existing incomplete blocks from a limitation on block length.
   3.   Block faces exceeding 500 feet must be subdivided with a sidewalk extending through the block that is 12 feet wide, minimum.
   4.   Rear alleys are required for medium and high intensity areas in the BU zone and in DT and DN zones. Rear alleys are not mandatory where the rear lot lines are at the edge of the site to be subdivided or where the block has been previously subdivided.
D.   Intersection sight visibility distances are determined based on the subdivision street standards, except that sight visibility zones are not required for mixed-use zone intersections controlled by a traffic signal or stop sign.
E.   Streets in mixed-use zones must be designed as follows:
   1.   Streets classified as arterials shall use the avenue street cross section (table 14, cross section 1)
   2.   Streets classified as collectors shall use the avenue or street cross section (table 14, cross section 1, 2, 3, or 4).
   3.   Streets classified as local roadways shall use the street cross section (table 14, cross section 2, 3, or 4).
   4.   As an alternative to the above, streets in the BU high intensity area and in the DT zone may use the commercial street-mixed parking or parking plaza street cross sections (table 14, cross section 7 or 8).
   5.   The alley cross section (table 14, cross section 5) may be used for secondary, service, or parking access.

17-4-11 Blended-use (BU)

The blended-use zoning district may be applied by process of rezoning to any parcel 40 acres or greater. The approval of rezoning to BU adopts the blended-use plan submitted by the applicant in conformance with this section and section 17-4-9 (Mixed-use zoning districts).
A.   Blended-use neighborhood types.
   1.   Aldea. This blended-use neighborhood type consists of no less than 40 acres and no more than 80 acres.
   2.   Pueblo. This blended-use neighborhood type has no less than 80 acres, and no more than 200 acres.
B.   Multiple neighborhoods must be developed under a single application on properties larger than 200 acres.
C.   Intensities. Aldeas and pueblos are comprised of land assigned to intensities rather than uses. The minimum and maximum percentage of the blended-use plan's total land area to be assigned to each intensity is given in table 15 below.

17-4-11 was amended for clarity in the introductory paragraph by Ordinance 17-4-11

17-4-12 Downtown Marana overlay (DO)

A.   Purpose. The DO is an overlay designation identifying geographic areas where owners of land may opt to replace their underlying zoning entitlements with the DN and DT zone designations.
B.   Application. To obtain DN and DT zoning in the DO district, one or more property owners must submit a downtown implementation plan, showing (at a minimum) the requested locations of DN and DT zone designations on their property.
C.   Administrative approval. The planning manager is authorized and directed to approve a downtown implementation plan that conforms to the requirements of sections 17-4-9 (Mixed-use zoning districts), 17-4-12 (Downtown Marana overlay (DO)), 17-4-13 (Downtown neighborhood (DN)), and 17-4-14 (Downtown (DT)), and meets the following minimum requirements:
   1.   The DT designation includes all land within 100 feet of the Marana Main Street right-of-way line.
   2.   The DN designation includes all land within 100 feet of the property line of all properties containing existing single-family residences, excluding any such property for which the property owner consents in writing.
   3.   The DN designation must be used for land that meets both of the previous two paragraphs.
D.   Council approval. Any downtown implementation plan not approved pursuant to paragraph C of this section may be submitted as an application for rezoning, which shall be reviewed through the normal rezoning process.
Ordinance 2024.010 amended paragraph C, removed paragraphs D and E, and renumbered paragraph F

17-4-13 Downtown neighborhood (DN)

A.   Purpose. The DN zone implements the Marana general plan by providing a transition from the DT to surrounding areas. This zone consists of a mix of uses but is primarily medium density residential. It may contain a wide range of building types: houses, courtyard housing, townhouses, duplexes, triplexes, apartment buildings, and live-work units.
