Off-street parking space shall be provided as further specified in this chapter, and shall be furnished with necessary passageways and driveways. All such space shall be deemed to be required space on the lot on which it is situated, and shall not be encroached upon or reduced in any manner. All parking areas, passageways, and driveways, except where provided in connection with one-family residences, shall be surfaced with a dustless, durable, all-weather pavement, clearly marked for car spaces, and shall be adequately drained, all subject to the approval of the borough engineer. The paving requirements for parking areas, passageways, and driveways serving eight or fewer vehicles may be waived by the building inspector, if a suitable crushed stone base approved by the borough engineer is substituted that satisfies all safety, drainage, erosion and other applicable engineering requirements.

Except where more restrictive provisions apply under the specific requirements for each zone district, no off-street parking space or portion thereof shall be located on any lot within five feet of any street line, or within five feet of any lot line.

None of the off-street parking facilities as required in this chapter shall apply to existing structures and uses. If, however, any existing structure is physically enlarged, or if any existing use is physically expanded, the parking requirements of this chapter shall apply only to the enlarged portion of such structure or the expanded portion of such use.

In the case of a change in use or occupancy of an existing structure, the parking requirements of this chapter shall apply only to any net increase in parking demand between the previous use or occupancy and the proposed use or occupancy.

In the case of dwelling conversions, two off-street parking spaces shall be provided for the added dwelling unit.

If, subsequent to the date of adoption of this chapter, a room is converted to a rented room, one off-street parking space shall be provided for each room newly converted to such use. The provision shall not apply to rooms rented prior to the date of adoption of this chapter.

The collective provision of off-street parking areas by two or more buildings or uses located on adjacent lots is permitted, provided that the total of such facilities shall not be less than the sum required of the various buildings or uses computed separately and further provided that the land upon which the collective facilities are located is owned or leased by one or more of the collective users.

All parking areas and appurtenant passageways and driveways serving commercial uses shall be illuminated adequately during the hours between sunset and sunrise when the use is in operation. Adequate shielding shall be provided by commercial users to protect adjacent residential zones from the glare of such illumination and from that of automobile headlights.

Off-street parking areas providing 20 or more parking spaces shall be designed to cause minimum interference with traffic on public streets and to insure ease of access. Such lots shall be provided with shade trees spaced not greater than 60 feet on center.

Off-street loading and unloading space, with proper access from a street or alley, shall be provided on any lot on which a building for trade or business is hereafter erected or substantially enlarged.

Off-street parking facilities provided to comply with the provisions of this chapter shall not subsequently be exceeded by reason of changes in conditions and shall at all times meet the requirements of this chapter.
