Opinion by
Judge Colins,This is an appeal by the Allegheny County Industrial Development Authority (appellant) from an opinion and order of the Court of Common Pleas of Allegheny County affirming the decision of the Pittsburgh Zoning Board of Adjustment which denied appellant’s request for a variance from Section 959.05 (e)(4)(l) of the Pittsburgh Code of Ordinances (Ordinance), the twenty percent (20%) open space requirement.
In 1979, appellant acquired certain real property at 14 Wood -Street in the City of Pittsburgh situated in an area zoned C5-0 Golden Triangle District C.1 Appellant leased this property to several individuals (lessees), who planned to renovate .the existing thirteen-story building and rebuild the five-story attached extension located .thereon.
The lessees applied to the Zoning Administrator of the City of Pittsburgh for a building permit. A site plan was submitted, indicating that a certain portion of the parking area would be reserved for a park, in conformity with the twenty percent (20%) open space requirement of Section 959.05(c) (4) (1). The *635site plan was approved on June 5, 1980, and the building permit was issued.
On September 15,1982, .the lessees2 sought an occupancy permit. The Zoning Administrator refused to issue this permit because the lessees sought to use the area previously se.t aside for the park as additional parking spaces. The lessees then applied for a variance, which was denied by the Board on May 12, 1982. An appeal was taken to the Court of Common Pleas of Allegheny County. On December 8, 1983, the Court of Common Pleas sustained the decision of the Board. An appeal to this Court followed.
Our scope of review where, as here, the Court below has taken no additional evidence is limited to a determination of whether the Board abused its discretion or committed an error of law. Somerton Civic Association v. Zoning Board of Adjustment, 80 Pa. Commonwealth Ct. 173, 471 A.2d 578 (1984).
Appellant argues that he is entitled to a variance from Section 959.05(c) (4) (1) of the Ordinance. We disagree.
Section 959.05(c) (4) (1), entitled “Usable Open .Space”, states that in a C-5 zoning district, there shall be provided and maintained open space, not less than “Twenty percent (20%) of the lot area provided at ground level plus that required for any dwelling unit ¡by Section 959.06(b) (4).”3 (Emphasis added.)
In order to obtain a variance, appellant must prove:
(1) .that the ordinance imposes unnecessary hardship on the property; (2) that the hard*636ship stems from unique physical characteristics of the property; (3) that the variance would not adversely impact on the health, safety or welfare of the general public; (4) that the hardship was not self-inflicted; and (5) that the variance sought is the minimum that will afford relief.
Vacca v. Zoning Hearing Board of the Borough of Dormont, 82 Pa. Commonwealth Ct. 192, 197, 475 A.2d 1329, 1331-32 (1984); Section 912 of the Pennsylvania Municipalities Planning Code, Act of July 31, 1968, P.L. 805, as amended, 53 P.S. §10912.
We conclude that the hardship sustained by appellant can only be described as self-inflicted.
Appellant knew or should have known that it would be bound by the site plan it submitted pursuant to Section 959.04(a) of the Ordinance, as this Section specifically provides that:
In each G5 District, every new or changed use of land and every structure hereafter erected, enlarged, or externally altered, except uses and structures permitted as conditional uses under Section 959.06(c)(1) and structures involving external alterations not in excess of fifty thousand dollars ($50,000) shall, in addition to conforming to any and all regulations pertaining thereto that are specifically set forth in this Zoning Ordinance, be in accord with a site plan or plans approved by the administrator. (Emphasis added.)
Furthermore, appellant has exceeded the minimum variance needed, as it requests not a minimum departure from the ordinance, but complete elimination of the open space requirement.
Finally, appellant argues that Section 959.05(c) (4) (1) of the Ordinance requires usable open space only when dwellings exist on the property. This argument is without merit.
*637Under Section 959.05(c) (4) (1), open space is required regardless of whether or not the structure on the subject lot has dwelling units. If the proposed use does have dwelling units, as part of the main use, then additional space is required.
We find no abuse of discretion, nor error of law in the trial court’s decision.
Accordingly, we affirm.
