Chapter 29: Unified Development Code · Article 4. Form and Development Controls
(a) Applicability.
(1) General requirements.
(i)
The standards of this section 29-4.3 shall apply to all development and redevelopment, unless specifically excluded or modified by another provision of this Code.
(ii) Required off-street parking areas in existence on November 19, 2001, shall not be reduced below, or if already less than, shall not be further reduced below, the requirements for such use as would be required for the use as a new use of a building, structure or premises under the provisions of this section.
(2) Exceptions.
(i) M-DT district (section 29-4.2).
(A) Development and redevelopment in the M-DT district is exempt from the minimum parking requirements in Table 4.3-1.
(B) Residential development and redevelopment in the M-DT district shall provide one-quarter (0.25) of one parking space per bedroom. For any newly constructed building containing twenty (20) or more bedrooms, the parking requirement shall increase to one-half (0.50) of one parking space per bedroom. This requirement may be satisfied on the site or within onequarter (0.25) mile (one thousand three hundred twenty (1,320) feet) of the site. Measurement of the walking distance shall be from entrance to entrance.
(C) If on-site parking is provided, it shall meet all other requirements of this section 29-4.3 and may not be located forward to the parking setback line pursuant to the building form standards in section 29-4.2 (M-DT district).
(D) On-street parking shall meet the on-street parking requirements in section 29-4.2(f)(2)(iv).
(E) Notwithstanding anything contained herein to the contrary, any new residential development in the M-DT district which contains twenty (20) or fewer bedrooms shall be exempt from all parking requirements contained in this section.
(ii) Small lots. No off-street parking shall be required for any non-residential primary use on a lot smaller than ten thousand (10,000) square feet in any mixed use district, provided no portion of the front lot line of the property is located within one hundred (100) feet of a residential district.
(iii) Planned development. The off-street parking requirements of this section shall serve as the standard from which to request different parking requirements for a proposed use in a PD (planned development) district. Following approval of a PD district that is subject to an approved site plan with parking requirements that differ from those in this section 29-4.3, the requirements of this section shall not apply to property located in that district. If an approved planned zoning district site plan is silent on any aspect of parking addressed by this section, the provisions of this section shall apply to that aspect of parking.
(iv) Historic properties.
(A) No new on-site parking shall be required for the redevelopment of historic structures. (B)
If an existing historic structure has on-site parking, such parking must be retained and conform to the city's current parking improvement standards (e.g., be paved), unless the director determines that compliance is impracticable or would compromise the historic character of the property or area.
(3) Residential districts. The following standards apply in all residential districts:
(i) No detached garage shall be located nearer than twenty (20) feet to the front lot line or behind the building front, whichever is greater.
(ii) Parking spaces for residential and non-residential uses, other than single-family and two-family dwellings, shall not be located in the required front yard.
(iii) Required parking spaces may be tandem spaces to serve one- and two-family dwellings only, as exhibited in the Figure 4.3-1, provided no portion of the parked vehicles extends into the public right of way or any separate street or sidewalk easement. Figure 4.3-1: Tandem Parking

(ii) Whenever the type of use of a building, structure or premises is changed to a new type of use permitted by this chapter, parking spaces and areas shall be provided as required by the provisions of this section for such new type of use.
(iii) Notwithstanding the provisions of subsections (i) and (ii) above, a permitted use that does not meet the parking requirements of this section may be converted to another permitted use without full compliance with the required number of parking spaces provided:
(A) The amount of parking available is at least seventy-five (75) percent of the parking required for the new use in Table 4.3-1.
(B) The applicant provides the maximum number of parking spaces able to be accommodated on the site while complying with all other provisions of this Code and without being required to remove or partially remove an existing structure.
(b) Parking requirements.
(1) Required parking spaces. The minimum off-street parking requirements for all uses allowed by this Code are listed in Table 4.3-1.

(c) Other parking requirements. For any use not listed in Table 4.3-1, the required minimum number of offstreet parking spaces shall be determined by the director based on the anticipated use and anticipated neighborhood and traffic congestion impacts.
(d) Parking alternatives. The director may approve applications containing alternatives to providing the number of off-street parking spaces required by Table 4.3-1, in accordance with the following standards:
(1) Transit incentives.
(i) The minimum number of off-street parking spaces required for any development or redevelopment of land located within one-quarter (¼) mile of the City of Columbia transit center or immediately adjacent to transit lines that serve as a connection point for at least four other transit lines, may be reduced by twenty (20) percent.
(ii) The minimum number of off-street parking spaces required for any development or redevelopment of lands zoned M-N (pedestrian) or M-C (transit), may be reduced by thirty (30) percent. This reduction may not be combined with the reductions in subsection (i) above.
(iii) Upon application of the owner, the parking requirement of a building or use may be reduced by five (5) percent if the lot or tract is at least two (2) acres, is located on a transit route, and the owner provides, at the owner's cost, transit pull-offs and transit rider shelters of a type and location acceptable to the city.
(iv) If an existing transit route, center, or zoning district is eliminated or changed in location, any development approved and built in conformance with this section 29-4.3 shall not be deemed nonconforming in terms of required parking.
(2) Shared parking. The director may approve joint parking facilities for development or uses with different operating hours or different peak business periods, if the shared parking complies with the following standards:
(i) Location. Shared parking facilities may be located on the same site as the proposed uses or within six hundred (600) feet, as measured along the roadway frontage(s) to the center of the parcels upon which the uses are located and have their primary entrance, if the uses are not on the same parcel. Off-site shared parking facilities shall be connected by sidewalks.
(ii) Shared parking facility parking space reduction. Where a joint parking facility meets the requirements of this subsection, the total off-site parking required for the uses may be reduced by the factors shown in Table 4.3-2. Total off-street parking required shall be the sum of the two
(2) parking requirements for the two (2) uses divided by the factors for that combination of uses
shown in Table 4.3-2. If more than two (2) uses share a parking lot or structure, the required parking shall be calculated by applying Table 4.3-2 to the two (2) uses with the largest parking requirements and then adding the required parking for the additional use(s).
(iii) Additional sharing permitted. As an alternative to the shared parking reduction factors in Table 4.3-2, the director may allow the following reductions in required parking:
(A) Up to fifty (50) percent of the parking spaces required for food, beverage, and indoor entertainment uses located within six hundred (600) feet of a non-residential use that is not normally open, used, or operated during the same hours; and
(B) Up to one hundred (100) percent of parking spaces required for religious assembly uses located within six hundred (600) feet of a non-residential use that is not normally open, used, or operated during the same hours.

Office and Other Commercial 1.3 1.5 1.7 1.2
(iv) Agreements. If the director determines that in the interest of the public safety and welfare there is a need to ensure shared parking facilities will continue to remain available indefinitely for the buildings or uses they serve, the director may require a written agreement assuring the continued availability of the shared parking spaces for the buildings or uses they serve. If required by the director, the agreement shall be on a form approved by the city counselor, or designee, and approved by the council.
(3)
Credit for public parking. Some or all of the required off-street parking spaces for a non-residential use may be waived by the director if publicly owned off-street parking is located within a one thousand (1,000) foot walking distance from the main entrance of the proposed use, and the director also determines that adequate parking spaces are available within the publicly owned parking area to accommodate the anticipated use.
(4) Credit for on-street parking. The director, after consultation with the director of public works, may credit on-street parking spaces against required off-street parking requirements if the on-street spaces are located within two hundred (250) feet of an entry of the building in which the use is located, if the director determines that those parking spaces are frequently not utilized by the public, are readily available for residents, patrons, or employees of the proposed use and structure and granting such credit will not otherwise impair the public health, safety or welfare.
(5) Additional parking reductions. The director may allow an additional reduction in the required number of parking spaces (less than what may be determined using the adjusted off-street parking calculations in subsections (1) to (4) above) if the applicant submits a parking demand study, prepared by a licensed engineer in accordance with guidelines promulgated by the director which establishes the basis for granting a reduced number of spaces, and the director determines the study accurately reflects the foreseeable parking demand for the building and use of the property. In authorizing additional reductions shared access easements or agreements to adjacent parking areas and/or driveways may be required.
(e) Maximum parking limit.
(1) M-DT district. In the M-DT district (section 29-4.2), maximum on-site parking is limited to one hundred fifty (150) percent of the minimum amount required for the same use in other mixed use districts, even though those minimums do not apply to the M-DT district.
(2) Retail, office, or personal service uses in mixed-use districts. For any single building that contains more than fifty thousand (50,000) square feet of gross floor area, in which a single-user or multiple users operate a use listed in the retail, office, or personal service categories in Table 29-3.1 (Permitted Use Table), maximum parking is limited to one hundred fifty (150) percent of the minimum amount required by Table 4.3-1 unless the following two conditions are met, in which case the maximum parking is limited to two hundred (200) percent of the minimum amount required by Table 4.3-1:
(i) The development site's landscaped area is not reduced to be less than fifteen (15) percent as a result of the increased parking; and
(ii) The interior parking lot landscaping area, when required by section 29-4.4(f), is increased to twenty (20) percent and complies with the tree planting and/or landscaping standards specified within subsections (1), (2), and (3) of section 29-4.4(f).
(3) The maximum amount of parking allowed for all other permitted uses is two hundred (200) percent of the minimum amount required by Table 4-3.1.

(1) Location.
(i) All required parking shall be provided on the lot(s) where the principal use is located unless otherwise provided by this chapter.
(ii) Off-street automobile parking facilities required by this section for all non-residential uses may be located either on the premises of the building or use or within one thousand (1,000) feet of such building or use.
(iii) In the M-N district, on-site parking for non-residential uses shall not be located closer to the primary street frontage of the lot than the front façade of the principal structure, except for one double-loaded row of parking, which may be located between the front building façade and the front lot line, if it is not located in a required front yard area. The option to include one doubleloaded row of parking in this location is not available on properties where the applicant has selected to use the "pedestrian" dimensional standards shown in sections 29-2.2(b)(2) (M-N district) and 29-4.1 (dimensional standards).
(iv) No portion of an off-street parking facility shall be located in a public street or sidewalk, parkway, alley, or other public right-of-way.
(v) In a residential district, no paved driveway or outdoor parking area shall be permitted to cover more than thirty (30) percent or five hundred (500) square feet, whichever is greater, of any required front yard or required rear yard area. The thirty (30) percent limit shall include areas included in driveways.

(ii) A permitted driveway may include a defined area for parking adjacent and attached to the driveway provided such extension does not occupy any part of a required front or side yard and complies with all provisions of sections 29-4.7(d) and (e). The extension must be paved in a material similar to that of the rest of the driveway.
(iii) Parking of vehicles in a direction perpendicular to the driveway is prohibited, except in the rear yard.
(iv)
In residential districts, rear yards may be used for open parking of automobiles, including trailers and similar type vehicles, on an approved dust-free surface, subject to the installation and maintenance of a screening device not less than four (4) feet or more than six (6) feet in height.
(v) The director may issue a temporary permit to allow parking that does not meet the requirements of subsections (i) through (iv) under section 29-6.4(h) (temporary parking permits).

(4) M-DT district. In the M-DT district (section 29-4.2), the director may alter or waive the requirements of this section 29-4.3(j) (off-street loading requirements) on a case-by-case basis if the applicant demonstrates that a specific standard is impractical or meaningless to achieve due to:
(i) Existence of historic buildings in areas where loading would need to be located;
(ii) Section 29-4.2 requirements that a building occupy the space where loading would need to be located; or
(iii) Other site limitations or circumstances that make strict adherence to these standards impracticable.
(k) Bicycle facilities. Any parking lot or structure containing ten (10) or more parking spaces shall provide adequate and safe on-site bicycle parking facilities in accordance with the following standards:
(1) Required bicycle spaces.
(i) Bicycle parking facilities shall be designed to accommodate the number of bicycle parking spaces, based on vehicle spaces, set forth in Table 4.3-6 below:
Table 4.3-6: Required Bicycle Parking Spaces
Vehicle Spaces Required Bicycle Spaces
10—50 4
51—99 8
100—199 12
200—299 15
300 or more 5 percent of the number of vehicle spaces or 50 space, whichever is
less
(ii) For parking lots required by other provisions of this chapter to have more than twenty-five (25) vehicle parking spaces, the required number of vehicle parking spaces may be reduced by one space for each required bicycle parking space installed.
(2) Design.
(i) Location. Bicycle parking facilities shall be:
(A) Located within fifty (50) feet of the main customer and employee entrances to the principle use provided such location does not impede ADA required access or compromise pedestrian or customer safety;
(B) Clearly designated or of standard bicycle rack design which does not require separate identification;
(C) Safely separated from vehicle maneuvering areas; and
(D) Located on the ground level when in a parking structure.
(ii) Minimum dimensional standards. Each bicycle parking space shall be at least:
(A) Six (6) feet long;
(B) Two (2) feet wide;
(C) Have a minimum overhead clearance of seven (7) feet; and
(D) If more than one bicycle rack is used, a minimum five-foot wide access aisle is required beside or between each row of bicycle racks.
(iii) Materials. Bicycle parking facilities shall be surfaced with all-weather material and maintained in a safe and well-maintained condition.
(iv) Security. Bicycle parking facilities shall be equipped with either a lockable enclosure (bicycle locker) or a permanent, secure, and stationary structure (bicycle rack) that supports the bicycle frame and to which the frame and both bicycle wheels can be locked (with removal of the front wheel) or where the frame and one wheel can be locked (if both wheels remain on the bicycle).
(l) Screening and landscaping. All parking facilities shall comply with the screening and landscaping requirements of sections 29.4-4 and 29-4.7.
(m) Permits and certification.
(1) Parking lots without an associated building permit shall be subject to separate permitting and inspecting during construction, as appropriate, and shall not be open for use until a certificate of occupancy has been issued by the department.
(2)
Prior to authorizing use of any parking area established under this section, or issuance of occupancy certificates for any uses dependent thereon, the director shall inspect and certify the parking area to be in compliance with these standards.
(n) Delayed construction of required parking. Upon application of the owner, up to twenty (20) percent of the parking required under this section may remain unimproved until such time as the director finds that it must be improved to adequately serve the parking demand. The director may approve a delayed construction of required parking if all of the following requirements are met:
(1) The initial occupancy of the premises will be adequately served by the lesser number of spaces;
(2) A site plan clearly indicating the location, pattern, and circulation to and from the deferred parking spaces is approved;
(3) The land area delineated for future parking is brought to finished grade and is landscaped;
(4) The land area delineated for future parking shall not be used for building, storage, loading or other purposes; and
