In the B-1 and B-2 zoning districts, where twenty-five percent (25%) or more of the frontage upon the same side of a street between two intersecting streets is occupied or partially occupied by a building or buildings with front yards of less depth than required by this chapter, or where the configuration of the ground is such that conformity with the front yard provisions of this chapter would work a hardship, the board of adjustment may permit modifications of the front yard requirements.

In a residential district, no fence, structure or shrubbery higher than three and one-half (3-1/2) feet above the established street grades shall be maintained within twenty (20) feet of any street intersection.

Open and unenclosed terraces or porches and eave and roof extensions may project into the required front yard for a distance not to exceed four feet; however, no supporting structure for such extensions may be located within the required front yard. An unenclosed canopy for a gasoline filling station may extend beyond the building line of a gasoline filling station shall mean the actual wall of the building [sic] and shall not be interpreted as being the curb of a walk or driveway or as the front of a canopy or the columns supporting same.

Where an official line has been established for future widening or opening of a street upon which a lot abuts, then the width of a front or side yard shall be measured from such official line to the nearest line of the building.

On a corner lot, the width of the yard along the side streets shall not be less than any required front yard on the same side of such street between intersecting streets; however, the buildable width of a lot of record shall not be reduced to less than thirty (30) feet.

No accessory building shall project beyond a required yard line along any street.

For the purpose of side yard regulations, a two-family dwelling or multifamily dwelling shall be considered as one building occupying one lot.

Where a lot of record at the time of the effective date of this chapter is less than fifty (50) feet in width the required side yard may be reduced to provide a minimum buildable width of thirty (30) feet; however, no side yard shall be less than five (5) feet.

The area required in a yard shall be open to the sky, unobstructed except for the ordinary projections of windowsills, belt courses, cornices or other ornamental features.

Accessible parking shall be provided in accordance with the standards of the Architectural Barriers [Act and the] Texas Accessibility Standards.

Floor area means the gross floor area of the specific use.

Where fractional spaces result, the parking spaces required shall be construed to be the nearest whole number.

The parking space requirement for a use not specifically mentioned in this chapter shall be the same as required for a use of similar nature.

Whenever a building or use constructed or established after the effective date of this chapter is changed or enlarged in floor area, number of employees, number of dwelling units, seating capacity or otherwise, to create a need for an increase of ten percent or more in the number of existing parking spaces, such spaces shall be provided on the basis of the enlargement or change. Whenever a building or use existing prior to the effective date of this chapter is enlarged to the extent of fifty percent (50%) or more in floor area or in the area used, the building or use shall then and thereafter comply with the parking requirements set forth in this chapter.

In the case of mixed uses, the parking spaces required shall equal the sum of the requirements of the various uses computed separately.

Where an increase in the number of spaces is required by a change or enlargement of use or where such spaces are provided collectively or used jointly by two or more buildings or establishments, the required spaces may be located not to exceed three hundred (300) feet from an institutional building served and not to exceed five hundred (500) feet from any other nonresidential building served.

Off-site, shared parking may be allowed for not more than fifty percent (50%) of the parking spaces required for:

For sixty degree (60°) angle parking, each parking space shall be not less than nine (9) feet wide perpendicular to the parking angle nor less than seventeen (17) feet in length when measured at right angles to the building or parking line. Maneuvering space shall be in addition to parking space and shall be not less than twenty (20) feet perpendicular to the building or parking line.

For forty-five degree (45°) angle parking, each parking space shall be not less than nine (9) feet wide perpendicular to the parking angle nor less than sixteen (16) feet in length when measured at right angles to the building or parking line. Maneuvering space shall be in addition to parking space and shall be not less than eighteen (18) feet perpendicular to the building or parking line.

When off-street parking facilities are located adjacent to a public alley, the width of the alley may be included in the calculation of the maneuvering space requirement.

Where off-street parking facilities are provided in excess of the minimum amounts specified in this section, or when off-street parking facilities are provided but not required by this chapter, the off-street parking facilities shall comply with the minimum requirements for parking and maneuvering space specified in this section.

In district B-2, one (1) loading space for each ten thousand (10,000) square feet or fraction of floor area in the building.
