Opinion by
This is an appeal from the refusal of the court below to declare void a Certificate of Occupancy issued by the Superintendent of the Bureau of Building Inspection of the City of Pittsburgh, permitting the use and occupancy of a certain dwelling as a synagogue and a residence for the Rabbi.
On November 13,1942, the Superintendent of the Bureau of Building Inspection, acting pursuant to the Zoning Ordinance of thе City of Pittsburgh, issued a Certificate of Occupancy to the Kahal Chasidim Congregatiоn authorizing the use of premises No. 5807 Bartlett Street as a synagogue and as a rеsidence for the Rabbi and his family. The premises are situate in a class “B” residentiаl district. An appeal was filed by Berthold Floersheim and others, appellants, with the Board of Adjustment. After public hearings on the appeal, the Board refused to revoke said certificate. Appeal was taken to the Court of Commоn Pleas, where the Kahal Chasidim Congregation was permitted to intervene. The decision of the Board of Adjustment was affirmed. This appeal followed.
The Zoning Ordinance classifies residential districts in classes “A”, “B”, and “C”. Section 9 of said Ordinance enumerates the permitted uses of land in class “B”. 1 The uses here involved are for a “One Family Dwell *100 ing” 2 and for a “Church”. Appellants cоntend that a Certificate of Occupancy cannot lawfully be issued which authоrizes a combination of these permitted uses.
Section 54 of the Ordinance grаnts broad powers to the Board of Adjustment.

We are concerned only with the power of that Board to issue the certificate authorizing a combination of permitted uses specifically enumerated in the Ordinance. The definition of а “One Family Dwelling” is broad.
4
A building “designed for” one family may very readily be used as a “church”. Nowhere in the Ordinance is there an express limitation upon the powers of thе Board which prevent it from permitting a combination of authorized uses. It cannоt be said as a matter of law that the Board does not have that power. Thе courts will not interfere with the exercise of an administrative duty by the officials entrustеd therewith unless it is shown that the action taken has been arbitrary, capricious and unreasonable or clearly in violation of positive law:
Jennings’
Appeal,
Appellаnts have argued that the manner in which the property has been used amounts to а nuisance and, therefore, their property rights are unreasonably endangered by the issuance of this permit. With this proposition we are not now concеrned. If, in fact, the use of the premises does constitute a nuisance, apрellants have a remedy in the proper form.
The order is affirmed at appellants’ cost.
