To  achieve these goals, this Zoning Code shall govern the height and size of buildings and  structures, the percentage of lots that may be occupied, the size of yards and open space,  the density of population and the location and use of buildings, structures and land for trade,  industry, residence or other purposes within the Billings city limits.

1. To promote and guide development consistent with the goals and objectives of the  Growth Policy and area plans;

2. To prevent waste and inefficiency in land use;  

3. To encourage innovations in residential development and renewal so that the needs of  the community for housing may be met by greater variety in type and design of dwellings  and by conservation of open space; and  

4. To provide adequate land and space for the development of commercial and industrial  uses and to encourage such developments in locations calculated to benefit the  community at large and in a manner consistent with the goals and objectives of the  Growth Policy and area plans.  

SECTION 27-103 SCOPE  

A. This chapter applies to all lands within the City of Billings.

B. In their interpretation and application, the provisions of this Zoning Code may be regarded  as the minimum requirements for the protection of the public health, safety, comfort,  prosperity, and welfare.  

C. Whenever the requirements of this chapter are at variance with the requirements of any  other lawfully adopted rules, regulations, ordinances, deed restrictions or covenants, the  most restrictive or that imposing the higher standards shall govern.

CX Heavy Commercial

SECTION 27-402 DISTRICT DESCRIPTIONS

Commercial and mixed-use districts are primarily intended to allow a mix of uses within appropriately  scaled buildings to maintain and promote the desired physical character of the downtown and commercial  nodes and corridors within the city.

A. CBD: CENTRAL BUSINESS DISTRICT

The CBD district is the downtown mixed-use core intended to continue the existing character of the highly  walkable downtown commercial corridors with storefronts on the ground story and upper story residential,  lodging, and office uses.

B. DX: DOWNTOWN SUPPORT  

The DX district is intended primarily for use surrounding the (CBD) district and would accommodate highly  walkable, higher intensity office and residential uses in support of the CBD.

C. CMU1: CORRIDOR MIXED-USE

The CMU1 district is intended to accommodate commercial and other uses along transportation corridors  to promote development that is comfortably accessible via all modes of transportation, including motor  vehicles, bicycles, and walking. Commercial uses in the CMU1 district may be somewhat larger in scale  and more flexible than the neighborhood mixed-use district, including more auto-oriented uses such as  gas stations. While ground stories along streets are intended for commercial uses, the upper stories could  accommodate residential and/or office uses.

D. CMU2: CORRIDOR MIXED-USE AND COMMERCIAL CENTERS

The CMU2 district is similar in intent to CMU1, supporting commercial and other uses along transportation corridors to promote development that is comfortably accessible via all modes of transportation, including  motor vehicles, bicycles, and walking. CMU2 differs from CMU1 as it is meant to accommodate larger scale commercial, warehouse-style buildings, and other uses in multiple buildings on larger, deeper

CITY OF BILLINGS

ARTICLE 27-400 COMMERCIAL & MIXED-USE DISTRICTS

parcels along corridors. While ground stories along streets are intended for commercial uses, the upper  stories could accommodate residential and/or office uses.

E. NMU NEIGHBORHOOD MIXED-USE

The NMU district is intended to accommodate a mix of uses, primarily located along neighborhood  corridors that are highly walkable and accessible to pedestrians. Includes ground story uses focused on  daily needs primarily for adjacent neighborhood residents, such as corner stores, personal services, and  small restaurants. Upper stories accommodate residential and/or office uses.

F. NO: NEIGHBORHOOD OFFICE

The NO district is intended to accommodate office and office/residential uses on neighborhood corridors  and internal neighborhood locations where other commercial uses are inappropriate. This district is meant  to be highly walkable and accessible to pedestrians and to fit well with the context of adjacent  neighborhood residential buildings, when located on corners or block ends.

G. CX: HEAVY COMMERCIAL

The CX district is intended for heavy commercial, wholesale, warehouse-distribution facilities, and  contractor commercial uses. This district allows outdoor storage and accommodates truck traffic. This  district is intended to be located along corridors where proximity to residential and walkable mixed-use  development is limited. Basic setback and height parameters apply.

SECTION 27-403 REGULATIONS APPLICABLE TO ALL COMMERCIAL AND MIXED-USE  DISTRICTS  

All buildings must comply with the general regulations of this section and the specific regulations per each  district, unless otherwise expressly stated in this ordinance.

A. ALLOWED USES

Allowed uses are provided in Article 27-1000.

B. EXISTING BUILDINGS

Existing buildings are not required to meet these regulations except as defined in Article 27-1500. C. SITE ACCESS

All lots shall have one lot line located fully on a public or approved private street right-of-way.  D. PERMANENT STRUCTURES

All buildings constructed in any commercial and mixed-use district must be of permanent construction  without a chassis, hitch, or wheels, or other features that would make the structure mobile, unless  otherwise expressly stated in this code.

E. ACCESSORY STRUCTURE REGULATIONS

Accessory structures are subject to Article 27-1000. Uses, unless otherwise defined in these district  regulations.

CITY OF BILLINGS

ARTICLE 27-400 COMMERCIAL & MIXED-USE DISTRICTS

F. EXCEPTIONS AND EXEMPTIONS

The following exceptions and exemptions may apply to the district site and structure regulations. Use  specific standards in Article 27-1000 are still applicable.

1. Administrative Relief. Article 27-1600 defines administrative relief applicable to the site and  structure regulations. Additional administrative relief may be noted throughout this article. 2. Outdoor Recreation Uses. Outdoor parks, recreation, outdoor participant sports, and recreation  uses are exempt from compliance with district site and structure regulations, except that:

(a) If a building is incorporated, the building shall meet the regulations of either an accessory  kiosk per 27-1000 or an allowed building type.

(b) Side and rear setbacks for any applicable district must be met.

3. Utility Structures. The following structures are not required to comply with site and structure  regulations applicable to a specific district.  

(a) Wireless communications facilities and uses 27-1000.

(b) Public and private utility stations, substations, and associated utility station facilities.

4. Civic and Institutional Uses. Civic and institutional uses allowed in the district are required to the  meet the district site and structure regulations, except the following applies:

(a) The minimum dimension of any build-to zone shall be treated as a minimum setback.

(b) Minimum heights are not required. Heights above the maximum allowed may be approved  through an Administrative Relief, based upon similar civic structures on similar lots in the  surrounding neighborhood. See Article 27-1600 for design exception procedure.

(c) Window, front door, and roof regulations are not required.

G. YARD TREATMENT

All yards must consist of landscape areas, patio space, or sidewalk space, unless otherwise expressly  stated. Paved vehicular areas are limited to specific locations per the applicable district site and structure  regulations. Driveways may cross through yards as follows:

1. Where permitted as access to the lot, driveways may cross perpendicularly through the front or  street side yards, except as otherwise expressly stated.

2. In all commercial and mixed-use districts, driveways may cross perpendicularly through the side  and rear yards to connect to parking on adjacent lots.  

3. Side Yard Parking Lots. Some districts permit side yard parking lots. Side yard parking lots must  not encroach on the front yard and must not encroach upon the minimum side setback, except  as otherwise expressly stated.  

4. Rear Yards. Paved vehicular areas (parking lots, loading areas, drives) are typically required to  be located in the rear yard; however, minimum rear yard setbacks also apply to parking lots,  unless otherwise stated.

H. FRONT AND SIDE STREET FRONTAGES

Per the district regulations, certain site and structure regulations apply to building facades and edges  along front and side streets. For example, windows and a principal entrance may be required, or parking

March 2020 Public Review Draft | 3

CITY OF BILLINGS

ARTICLE 27-400 COMMERCIAL & MIXED-USE DISTRICTS

locations, driveways, and garage entrances may be restricted along these street frontages. Front lot lines  must be provided as follows:

1. Establishment. All parcels must have a front lot line established by one of the following methods.  (a) For lots with only one lot line abutting a street, that lot line shall be the front lot line.

(b) For lots on corners, front lot lines are established by the director, based upon an approved  Planned Neighborhood District (PND), the street classification, or the orientation of adjacent  and abutting buildings.

(c) For CMU1 and CMU2 districts, when a new street is established perpendicular to a front  street listed above, the director may approve the use of the new street for the front lot line,  provided the new perpendicular street is at least 300 feet in length, connects to another  street at both ends, provides a second way out of the development, and is treated with  streetscape, sidewalks, and on-street parking.

(d) For NMU or NO districts located on corners of primarily residential neighborhoods, the side  street is the preferred location of the front lot line with the intent of locating business  entrances off side streets as opposed to sharing the front street with residential entrances.

(e) Multiple Front Streets. If multiple front streets abut a lot, the front line may be designated by  the director, considering the following:

(1) The configuration of other parcels along the street, including fronts of buildings and  locations of vehicular access, are more consistent with street-side lot line requirements;  and

(2) No plans for front street designation in the future exist for the proposed street-side  frontage.

2. Open Space Frontage. Where a lot or parcel contains or abuts open space designated as a P1 district, the frontage of a building abutting the open space must comply with front lot line requirements.

3. Main Parking Lots. Where a main parking lot is internal to a site, the facades fronting the main  parking lot must be treated as front facades.

4. Through Lots. Where a lot extends between two front streets essentially parallel to each other,  both frontages shall be treated as front lot lines.  

(a) Where a commercial and mixed-use district double frontage lot is deeper than 120 feet and  shares a front street with an N district, residential development shall be provided consistent  with front lot line requirements for any NX district.

(b) Where a commercial and mixed-use district double frontage lot shares a front street with an  N district, the rear of all buildings shall be screened from any front street by another building or landscape screening.

5. Corners. At corners of buildings on streets, front lot line façade treatments, including, but not  limited to, ground-story doors and windows must be continued around the corner along the side  street for a minimum of 30 feet.

I. TRASH, RECYCLING, REFUSE LOCATIONS

Unless otherwise defined by the site and structure regulations, all trash, recycling, and other refuse areas  must be located and treated as follows:

March 2020 Public Review Draft | 4

CITY OF BILLINGS

ARTICLE 27-400 COMMERCIAL & MIXED-USE DISTRICTS

1. Trash, recycling, and other refuse areas must be located in the rear yard of the lot or in the alley  with city approval.

2. When no rear yard exists or when the rear yard is less than 10 feet in depth, trash, recycling,  and other refuse areas may be located in the rear portion of an interior side yard.  3. Trash, recycling, and other refuse areas may be located inside the building with access doors  off the rear or interior side facade. Access doors must be opaque, screening a minimum of 80%  of the opening.

4. See Article 27-1200 for required screening of trash, recycling, and other refuse areas. J. FRONT ENTRANCES

The following applies only when required by the site and structure regulations for the district. Front building entrances shall be emphasized, adding interest to the building façade, through one or more of the  following design features:

1. Roof or Canopy. The entrance is covered by a roof or canopy differentiating it from the overall  building roof type.

2. Porch. The entrance is through a porch.

3. Sidelights and Transom. Sidelights and/or transom windows are included abutting the entrance  door.

4. Recessed or Projecting Bay. The entrance is located in a separate bay of the building that is  either recessed or projected from the front façade.  

5. Other Design. Other designs adding emphasis and drawing attention to the entrance on the  facade may be approved with a design exception.

K. ARTERIAL SETBACKS

Minimum arterial setbacks as follows apply to all commercial and mixed-use districts, except EBURD, CBD and DX districts:

CITY OF BILLINGS ARTICLE 27-700 PLANNED DEVELOPMENT

SECTION 27-701 INTENT

A. The intent of planned development zoning is to provide flexible land use and design  regulations through the creation of individualized planned developments (PD) that both meet  the City’s growth policies and provide a specific benefit to the community.  

B. It is further intended that each PD zone will be a separate zone, each having differing design  criteria to provide for the uses and improvements based on its particular site-specific  situation.  

C. A PD zone is intended to replace the previous zoning classification of the subject property.  Areas rezoned in accordance with this chapter shall be designated with a distinct name in  reference to the owner or place. For example, Willowbrook or Shiloh Village are distinct PD  names.  

D. The PD zoning district is unique among the zoning districts in that it allows zoning and/or  site development standards to be "customized" to fit its particular site and/or development  situation. With due consideration of public health, safety, and the general welfare, the city  council can approve a PD that permits greater or lesser standards in such areas as use,  bulk, height, parking, signage, landscaping, lot sizes or other elements. This may also  include permitting the development of civic or recreational amenities such as religious  centers, schools, tennis centers, swimming centers, and other recreational activities such as  an equestrian center within the City limits, provided that such an amenity is an integral part  of the overall development scheme of the PD. However, these considerations for allowing  greater or lesser standards should be balanced within the PD. For example, permitting a  wider range of uses in a PD could be approved, in exchange for a greater amount of open  space than a similar project, not located in a planned development zone, would be required  to provide.  

SECTION 27-702 OBJECTIVES

The planned development shall be designed to meet the following objectives:

A. To permit the development of planned industrial, commercial, or mixed-use development  zones, while protecting the character and quality of adjacent uses.  

B. To permit flexibility in design and use of an individually owned property or a group of  separately owned properties to allow for economy, convenience and amenity in  development.  

C. Preserve, enhance, and retain the existing natural environmental qualities in the landscape  such as topographic variation, views, water areas and native vegetation.  

SECTION 27-703 APPLICABILITY

A. PD zoning is applicable to parcels of 10 acres or greater.

B. PD zoning is not applicable as a rezoning option in areas zoned N1-3, NX 1-3, NO, NMU,  CMU1, CMU2, DX, or EBURD.

C. PD zoning is separate from and may not be used as a substitution for or in conjunction with  PND zoning. Any PD project proposals will be evaluated for the applicability of a PND before  starting the PD process.

March 2020 Public Review Draft | 1

CITY OF BILLINGS ARTICLE 27-700 PLANNED DEVELOPMENT

A. Pre-Existing PDs may not be expanded unless the existing district plus the expansion will  meet the 10-acre minimum size requirement.

B. Where the terms of a Pre-Existing PD are silent as to a specific aspect of development, the  provisions of this Zoning Code apply. An applicant may seek a zoning code interpretation  to determine relevant standards.

C. Modifications to a Pre-Existing Planned Development shall be processed using the same  procedure as that for a new PD application unless a specific procedure was agreed to and  memorialized as part of the original PD adoption.
