18.78.010 Specific purposes.

The purpose of the off-street parking and loading regulations is to:

A. Ensure that off-street parking and loading facilities are provided for new land uses and for major alterations and enlargements of existing uses in proportion to the need for such facilities created by each use;

B. Establish parking standards for land uses consistent with need and with the feasibility of providing parking on specific land sites;

C. Ensure that off-street parking and loading facilities are designed in a manner that will ensure efficiency, protect the public safety, and, where appropriate, insulate surrounding land uses from adverse impacts. [Ord. 07-1284 § 3 (Exh. F), 2007; Ord. 979 § 2 (Exh. A), 1990.]

18.78.020 Applicability.

The regulations of this chapter apply to each zoning district established by this title except as may be modified by a PD or overlay zone. [Ord. 07-1284 § 3 (Exh. F), 2007; Ord. 979 § 2 (Exh. A), 1990.]

18.78.030 Basic requirements.

A. When Required. Off-street parking facilities and off-street loading facilities must be provided in accord with the regulations prescribed in this chapter at the time of either:

1. Initial occupancy by a use of an undeveloped site;

2. Construction of a structure;

3. Change in use classification of a building or site which creates an increase in the number of required parking spaces or loading berths;

4. Addition to, or enlargement of, an existing building or use.

B. Retention of Existing Parking or Loading. An existing use of land or structure is not considered nonconforming solely because of the lack of off-street parking or loading facilities required by this chapter. A facility being used for off-street parking and loading on March 19, 1990, may not be reduced in number to less than that required by this chapter, nor may the building be altered in design or function to less than the minimum standards required by this chapter for the duration of that use, unless a substitute facility is provided as prescribed by the regulations of this chapter.

C. Alterations or Enlargements. The number of parking spaces or loading berths required on the site of an addition, new structure, enlargement of a use by the alteration of existing structure, or for a change in use classification that would increase the number of spaces required, is only the number of spaces required for such structure, addition, enlargement, or difference in requirement of the new use and that required of the previous use as prescribed by this chapter, and not for the entire building or use. These provisions do not apply to an addition to a residential use that does not create additional dwelling units, nor to a nonresidential addition, structure, enlargement, or change of use that would increase the number of parking spaces by not more than five percent of the total number required before the alteration or enlargement.

D. Excess On-Site Parking or Loading. Where the number of parking spaces or loading berths on a site exceeds the number prescribed in this chapter for an existing use, the excess spaces or berths may be counted in determining the required number of spaces or berths for an expanded use on the site or towards the requirement for another use.

E. Sites with Multiple Uses.

1. Parking Spaces Required. If more than one use is located on a site other than as may be prescribed for a particular use classification the number of off-street parking spaces required is the sum of the requirements prescribed for each use, except as provided in subsection (E)(3) of this section.

2. Joint Use. An off-street parking facility required by this chapter for one use may not provide parking spaces for any other use except where subsection (D) of this section applies or a joint facility exists. A joint facility must contain not less than the total number of spaces as determined individually, or as required by subsection (E)(3) of this section. However, fewer spaces may be permitted where adjoining uses on the same site have different hours of operation and the same parking spaces can serve both without conflict. In order to allow fewer spaces than prescribed, the planning commission must make findings to determine the extent, if any, to which joint use will achieve the purpose of this chapter.

3. Shopping Center Parking Requirement. The parking standards prescribed for retail sales are used to determine the number of off-street parking spaces required for all use classifications that are permitted when located within a shopping center by using the aggregate gross floor area of all such uses. Any use classification that requires a use permit or is on a separate parcel within a shopping center site must provide parking as required for that individual use, except as may be modified by the provisions of subsection (E)(2) or (F) of this section.

4. Loading Facilities. If the gross floor area of an individual use on the same site is less than that for which a loading berth would be required by Schedule B of PMC 18.78.040, but the aggregate gross floor area of all uses is greater than the minimum for which loading berths would be required, the aggregate gross floor area is used in determining the required number of loading berths.

Off-street loading facility requirements of this chapter may be satisfied by the permanent allocation of the prescribed number of berths for each use in a common truck loading facility. The total number of berths may not be less than the sum of the individual requirements.

F. Location and Ownership.

1. R Districts. Required parking for a residential use in an R district must be on the same site as the use served. Additional parking may be provided on another site or within a nonresidential zoning district. Off-site parking for a nonresidential use in an R district is not permitted unless the nonresidential use served is permitted or conditionally permitted in the R district where the off-site facility is proposed to be located.

2. Nonresidential Districts. Parking required to serve a nonresidential use may be on the same or a different site under the same or different ownership as the use served so long as that parking is within 200 feet of the use served, measured from the near corner of the parking facility to the entrance of the use served via the shortest pedestrian route.

The facility for off-site parking must be restricted to that use by a recorded deed, lease, or agreement for a minimum period of 10 years from the date a zoning permit requiring the parking is issued. No use may be continued if the parking is removed unless a substitute parking facility is provided.

G. Reserved Parking Spaces. Required parking spaces may be reserved for the exclusive use of an individual tenant or use as follows:

1. Multifamily Residential Uses. No more than one space per dwelling unit in a multifamily dwelling containing more than four units.

2. Nonresidential Uses. No more than the minimum number of spaces required for the area occupied by an individual nonresidential tenant or use located in a joint facility.

Sites providing parking spaces in addition to the minimum required for the use or uses may assign exclusive use to individual tenants or uses for such additional parking.

H. Use of Parking Facilities.

1. Required parking spaces, as prescribed by this chapter, may be used only for the temporary parking of vehicles of the residents, guests, employees, customers, or other legitimate visitors of the site.

2. No sales, storage, repair, dismantling, or servicing of any kind is permitted in any required parking space, aisle, or driveway, except as allowed in a residential district pursuant to PMC 18.50.200 through 18.50.210.

3. Use of parking facilities not otherwise required is allowed only as provided in this chapter.

4. A vehicle parked in a required parking space must be operable and registered.

5. Automobiles may be continuously parked in a required space no more than five consecutive days, unless it is a reserved space prescribed by subsection (G) of this section, or is for a single-family dwelling or duplex.

6. No overnight parking is allowed for recreation vehicles, trucks, or other equipment, unless specifically permitted by other provisions of this title.

7. No overnight habitation within an automobile is allowed. [Ord. 07-1284 § 3 (Exh. F), 2007; Ord. 979 § 2 (Exh. A), 1990.]

18.78.040 Off-street parking and loading spaces required by type of use.

A. Parking Spaces Required. Independently accessible off-street parking spaces must be provided in accord with Schedule A as set out in this section.

B. Loading Berths Required. Independently accessible off-street loading berths must be provided in accord with Schedule B as set out in this section. The reference in Schedule A to group number for off-street loading is to the group number in Schedule B, which sets space requirements for different groups of use classifications and sizes of buildings.

C. Computation of Spaces Required. If, in applying the requirements of this chapter, a fractional number is obtained, one parking space or loading berth is required for a fraction of one-half or more. A space or berth is not required for a fraction of less than one-half.

D. Square Foot References. The references to spaces per square foot are to be computed on the basis of gross floor area as defined by this title, unless otherwise specified.

E. Seat Equivalency. Use classifications requiring parking based on the number of seats are to use only such tables, chairs, booths, stools, pews, or benches that are attached or specifically designed for a particular situation. Where such seating is not fixed or is readily movable, seating for dining purposes is considered to occupy 15 square feet of floor area per seat, and seating for assembly or classroom purposes is considered to occupy seven square feet of floor area per seat. A pew or bench seat is considered to be 24 inches in width for the purposes of this chapter. Seating area, as used in this chapter, is considered to be all that area planned for or that may be used for seating, exclusive of any necessary peripheral or emergency access aisles.

F. Uses Not Specified. If a use permit is required to establish a use, and the use classification is not included in Schedule A, the planning commission or zoning administrator, as appropriate, shall determine the required number of parking or loading spaces for the use in conjunction with the commission’s or zoning administrator’s review of the use permit. If the use is a permitted use, and the use classification is not included in Schedule A, the zoning administrator or the planning commission, as appropriate, shall determine the parking and loading requirements as part of the zoning approval process (Chapter 18.32 PMC).

G. Exceptions for Downtown and Residential Infill Units. Any proposed use and/or application for development activity on property located near transit or within the downtown subarea of the general plan shall be subject to the minimum off-street parking and loading spaces required by this section, with the following exceptions:

1. Residential Units Near Transit. The developer of residential units on an infill site located within one-quarter mile of bus, rail, shuttle or other mass transit station or facility may request a reduction in the number of off-street parking spaces required for the use. The residential units may be multifamily residential units, single-family residential units constructed on lots with a maximum lot size of 4,500 square feet, or a combination of the two. The zoning administrator or the planning commission, as appropriate, may not approve the request for reduced off-street parking unless it finds that the requested reduction in off-street parking is equivalent to the reduced demand for on-site parking as a result of the site’s proximity to transit.

2. Multifamily Residential Units within the Downtown Subarea of the General Plan. The off-street parking requirement for multifamily residential projects in the downtown subarea of the general plan shall be one and one-half parking spaces per unit. The developer of multifamily residential units in the downtown subarea of the general plan may request a reduction in the number of off-street parking spaces required for the multifamily residential use. The zoning administrator or the planning commission, as appropriate, may not approve the request for reduced off-street parking unless it finds that the proposed parking ratio will not negatively impact the parking facilities in the area, or, for existing buildings, that the provision of parking in accordance with this title would result in undue hardship in the improvement of the property and would result in an inconsistency with adopted design review guidelines in support of pedestrian-oriented storefronts.

3. Nonresidential Uses in the CP District. Nonresidential uses on properties located in the CP district shall not be subject to the minimum off-street parking and loading spaces required by this section.

4. Railroad Avenue Specific Plan and Pittsburg/Bay Point BART Master Plan. Vehicular and bicycle parking requirements for development located within the Railroad Avenue specific plan or the Pittsburg/Bay Point BART master plan area shall be those of the applicable specific plan or master plan.

H. Subject to approval of a use permit, the net number of parking spaces required in Schedule A of this section may be reduced by up to 25 percent. A use permit for a parking reduction under this section may be granted only after a determination that:

1. The applicable findings required for approval of a use permit under PMC 18.16.040 can be made;

2. As demonstrated by a parking study, due to special circumstances, such as the nature of the use, proximity to transit, transportation characteristics of the use, or implementation of a transportation demand management program, there will be a reduced demand and/or need for parking at the site; and

3. The applicant has demonstrated that the project could provide additional parking in the future if the parking demand increases. [Ord. 21-1497 § 2, 2021; Ord. 15-1390 § 3 (Exh. C), 2015; Ord. 11-1350 § 3, 2011; Ord. 07-1284 § 3 (Exh. F), 2007; Ord. 05-1257 § 4, 2005; Ord. 1060 § 7 (Exh. C), 1993; Ord. 979 § 2 (Exh. A), 1990.]

[Ord. 07-1284 § 3 (Exh. F), 2007; Ord. 05-1257 § 4, 2005.]

18.78.050 Parking facility design standards.

A. Parking Space Dimensions. The minimum dimensions of each required automobile parking space are as follows:

Use	Type of Space	Width and Length (Ft.)
Residential	In a separate garage or carport housing 4 or fewer cars, or with a door at the rear of each space	10 × 20
Residential	In a garage or carport housing more than 4 cars with access via an aisle or an uncovered space	9 × 18
Nonresidential	All nonparallel spaces	9 × 18
All	Parallel spaces	8 × 22

1. Increased Space Width Requirements. Each uncovered parking space adjoining a wall, column, or other obstruction higher than one-half foot and more than six feet from the front of the space must be increased in width one foot on each unobstructed side.

2. Vertical Clearance. Vertical clearance for each parking space must be at least seven feet, except that an entrance may be 6.67 feet and the front five feet of a parking space serving a residential use may be four and one-half feet.

3. Wheel Stops. Each parking space must have the centerline of a wheel stop at least two and one-half feet from any fence or wall. When a parking space abuts a landscaped planter, the front two feet of the required length for a parking space may overhang the planter, including the curb. When a parking space abuts a walkway, the front two feet of the required length of a parking space may overhang the walkway, including the curb, if the walkway is at least seven feet wide; otherwise the full length must be provided and a wheel stop installed two feet from the walkway.

4. Carport Dimensions. A carport roof must completely cover a required covered parking space and provide a minimum vertical clearance as prescribed in subsection (A)(2) of this section with a maximum clearance of 10 feet.

5. Parking Space Location. A paved parking space serving a single-family dwelling may not be located in that portion of a front or corner side yard which is more than a distance equal to one-half of the lot width or, in the case of a corner lot, the lot depth measured from the interior lot line. This does not pertain to a flag lot or lot described in PMC 18.80.050. No more than 50 percent of required front yard area shall be paved for parking, with the exception of paving necessary for walkways and paseos subject to review and approval by the zoning administrator.

6. Parking Space Length Reduction. Nonresidential buildings over 50,000 square feet or nonresidential buildings totaling over 50,000 square feet on a site may have up to 20 percent of the required parking spaces reduced to 15 feet in length where the front two feet of the standard space is either a landscaped area or light standard.

B. Aisle Dimensions. The minimum aisle widths adjoining parking spaces are as follows:

Minimum Aisle Width for Specified Angle (Ft.)

Angle with Parking Space	One-Way Traffic	Two-Way Traffic	Depth of Space (Ft.) Perpendicular to Aisle
90 degrees	25	25	18.0
60 degrees	16	23	20.5
45 degrees	12	22	19.5
30 degrees	11	21	17.3
0 degrees	12	24	8.0

1. Decrease in Aisle Width Allowed. Aisle widths may be decreased for parking angles of 90 degrees by one foot per one-quarter-foot increase in parking space width up to a maximum reduction of aisle of four feet; provided, that a two-way traffic aisle may be no less than 21 feet in width.

2. Extension of Aisle Required. An aisle providing access to a parking space perpendicular to the aisle must extend three feet beyond the required width of the parking space.

C. Driveway Dimensions and Clearances. A driveway must have the following width plus a minimum of one foot additional clearance on each side of a vertical obstruction exceeding one-half foot in height:

Use Driveway Serves	Driveway Width (Ft.)
	One-Way Traffic	Two-Way Traffic
Residential (10 or fewer spaces)	10	10
Residential (11 or more spaces)	12	20
Nonresidential (4 or fewer spaces)	12	12
Nonresidential (5 or more spaces)	12	20

1. Fire Department Standards. Notwithstanding the above regulations, all driveways must comply with the standards prescribed by the Contra Costa County fire protection district for access roads and fire lanes.

2. Driveway Approach Widths. The widths of the driveway approach apron or curb returns between a street and driveway may be no less than 15 feet for one-way traffic and 25 feet for two-way traffic. A greater width may be required by the city engineer depending upon the type or volume of vehicles served by the use, or design characteristics of the parking lot or access street.

3. Driveway Visibility at Street. The visibility of a driveway crossing a street property line may not be blocked between a height of three and one-half feet and seven feet for a depth of five feet from the street property line as viewed from the edge of the right-of-way on either side of the driveway at a distance of 50 feet or at the nearest property line intersecting the street property line, whichever is less.

D. Parking Spaces for the Handicapped. Every parking facility shall comply with the requirements of the California Administrative Code (Title 24, Part 2, Chapter 2-71) and with the sign requirements of Section 22507.8 of the California Vehicle Code.

E. Access to Parking.

1. Design of Space Access. A required parking space must be designed in such a manner that an automobile may enter the space with no backup movements and exit the space with only one backup movement. Access to a parking space which requires backing across a street property line is not permitted except in the case of parking serving a single-family dwelling or duplex. An alley may be used as maneuvering space for access to off-street parking.

2. Tandem Parking Spaces. A required parking space must be accessed without moving any other vehicle, except that a single-family dwelling or duplex may have two required spaces in tandem.

3. Parking Lot Access. A parking lot must be accessed by at least one two-way driveway or a one-way driveway for each direction. A parking lot that contains 10 or fewer parking spaces and is not more than 100 feet from the street to which it has access may be connected with a one-way driveway between the street and parking lot.

F. Lighting. Outdoor lighting for an off-street parking facility or lighting within a parking structure may not employ a light source that causes any direct illumination on an adjacent street or an adjacent lot in residential use.

G. Parking Lot Landscaping. Landscaping within a parking lot must be as prescribed in PMC 18.84.300 through 18.84.330.

H. Parking Area Screening. Screening of a parking area with a wall or fence must be as prescribed in PMC 18.84.200 through 18.84.235.

I. Additional Design Standards for Parking Facility.

1. Surfacing. Each required parking space and every aisle and driveway must be paved and be bounded by PCC curbing one-half foot in height. The curbing requirement does not apply to a single-family dwelling or duplex.

2. Grading and Drainage. An off-street parking facility must be graded to prevent standing pools of water and be provided with permanent storm drainage facilities to alleviate the creation of flooding and drainage problems for the site and surrounding properties. Driveway grades may not exceed 16 percent.

3. Safety. Safety barriers, protective bumpers, directional markers, or space stripping may be required to assure safety and protection to landscaping and structures.

4. Maintenance. An off-street parking facility must be maintained free of refuse, debris and weeds, kept in good repair, and at all times be available for the parking use for which it is intended.

5. Temporary Parking Lots. Temporary or nonrequired parking lots or accessways must be surfaced and graded as approved by the city engineer. [Ord. 23-1509 § 21, 2023; Ord. 15-1390 § 3 (Exh. C), 2015; Ord. 07-1294 § 3, 2007; Ord. 07-1284 § 3

(Exh. F), 2007; Ord. 05-1257 § 4, 2005; Ord. 979 § 2 (Exh. A), 1990.]

18.78.060 Location and design of off-street loading spaces.

A. Dimensions. Each required off-street loading berth must be a minimum of 12 feet in width, 30 feet in length, and have a minimum height clearance of 14 feet.

B. Location. A loading area may not be located in a required yard, nor may the loading operation for any use required to provide off-street loading facilities be permitted within any street right-of-way or required front or side yard.
