Opinion by
This is an appeal from an order of the County Court of Allegheny County which reversed an order of the Board of Adjustment [Board] of the Borough of Forest Hills [Borough] affirming the refusal of a permit for the erection of a gasoline service station.
John Hanna and Florence M. Hanna, his wife, [Hannas] in 1954 purchased a lot, improved with a frame dwelling house and a detached frame garage, located at the southeastern corner of Filmore Road and Greensburg Pike in Forest Hills Borough. At that time this lot was in a zoning district classified under the Borough zoning ordinance as “Z-l Commercial” and from that time until February 10, 1958 Hannas occupied the frame dwelling as a residence. On Feb *308 ruary 10, 1958, Hannas began a used ear business on tbeir land maintaining a business office for that purpose in part of the frame dwelling. On or about March 1,1958 the used car sales office was moved from the frame dwelling to the garage and on or about March 1, 1959 Hannas leased the dwelling house as a residence but continued to use the garage and lot for the used car business.
On February 12, 1958, the Borough amended its zoning ordinance and changed the zone classification in the district wherein Hannas’ property was located from Z-l Commercial to Z-2 Class A Residential. On October 23, 1958, Hannas were arrested and charged with a violation of the zoning ordinance for maintaining an office and for engaging in the used car business in the newly classified district but this charge was dismissed by the Burgess of the Borough on the ground that the Borough had failed to establish that Hannas had begun the used car business subsequent to February 12, 1958, the date upon which the ordinance was amended. From February 10, 1958 until the time of the present appeal Hannas have continued to conduct a used car sales business upon the premises.
On January 12, 1960, Hannas gave an option to Socony-Mobil Oil Company [Socony] to purchase the property for use as a gasoline service station and on August 4, 1960 Socony exercised its option. On August 29, 1960, Hannas and Socony appealed to the Borough building committee for a permit to build and conduct á gasoline service station on the premises. The plans for the proposed construction provided for the demolition of both the present frame dwelling and garage and the erection of a gasoline service station type building with appurtenant equipment such as tanks and pumps. * *309 Tlie building committee refused to issue a permit whereupon Hannas and Socony appealed to the Board. The Board, after hearing, affirmed the building committee’s action upon the ground that approval of the application would violate Sections 10(a), (b), (c) of the zoning ordinance. On appeal the County Court reversed the Board and from its order this appeal was taken.
The pertinent provisions of the zoning ordinance are: “Section 10. non-confohming uses, (a) The lawful use of land existing at the time of the adoption of this ordinance, although such use does not conform to the provisions hereof, may be continued; but if such non-conforming use is discontinued, any future use of said land shall be in conformity with the provisions of this ordinance, (b) The lawful use of a building existing at the time of the adoption of this ordinance may be continued, although such use does not conform to the provisions hereof, and such use may be extended throughout the building, provided no structural alterations are made other than those ordered by an authorized public officer to assure the safety of the building or structure, and provided further, that such extension does not displace any residence use in a Residence District. If no structural alterations are made, a nonconforming use of a building may be changed to another non-conforming use of the same or higher classification. (c) Whenever a use District shall be hereafter changed, any then existing non-conforming use in such changed district may be continued or changed to another non-conforming use of the same or higher classification, provided no structural alterations are made other than those ordered by an authorized public officer to assu[r]e safety of the building or structure.”
An analysis of Section 10(a) indicates that a nonconforming use of the land may continue until a discontinuance (that is, an abandonment) of such use *310 takes place. Under Section 10(b), a nonconforming nse of a building on the land may continue and such use may be extended throughout such building provided (a) no structural alterations (other than ordered by an authorized public officer for the building’s safety) 1 be made and (b) that the extension of such use does not displace a residence used in a residence district. Section 10(b) also provides that the nonconforming use of a building may be changed to another nonconforming use of the same or a higher classification if no structural alterations are made. In our view, Sections 10(a) and 10(b), except as they may throw some light on the construction of Section 10(c), are not applicable in the instant factual situation.
Section 10(c) controls the factual situation presented in the case at bar because the use district has been changed from commercial to residential. Section 10(c) provides that, where the use district has been changed, the nonconforming use may either continue or be changed to another nonconforming use of the same or a higher classification 2 provided no structural alterations be made other than ordered by an authorized public officer for the building’s safety.
What Socony contemplates is a complete demolition of the two existing buildings on this land and the erection of a gasoline station with the appurtenant tanks and pumps. Our initial inquiry must be to determine whether Sections 10(c) permits such a change.
A “structural alteration” is a change in an
existing
building which constitutes such a change or changes in
*311
an old building as converts the existing building into a new or substantially different structure:
Cole v. City of Battle Creek,
If, under Section 10(c), for the purpose of effecting a new use of the same or a higher classification an
existing
building cannot be altered (except as ordered by an authorized public officer for the building’s safety), a fortiori a
new
building cannot be erected. The prohibition of the erection of a
new
building is inherent and implicit in the provisions of Section 10(c). Other jurisdictions have reached the same result in the construction of zoning ordinances containing language similar to that in Section 10(c) ;
Rehfeld v. City and County of San Francisco,
Section 10(c), so construed, requires that we next inquire as to the validity of that section. A basic purpose of zoning is to ensure an orderly physical development of the city, borough, township or other community by confining particular uses of property to certain defined areas. With such a purpose nonconforming uses are inconsistent.
Molnar v. G. B. Henne & Co., Inc.,
In considering the plans for the new use of this property as a gasoline service station, the court below stated: “It might well be noted that the structures, the tanks, pumps, and, as the plans show, a new office need not necessarily be called buildings.” With that conclusion we disagree. While the “tanks” and “pumps” are not “buildings” within the sense of the ordinance
(Humphreys v. Stuart Realty Corp.,
This ordinance does not prohibit the expansion or broadening of the scope of the present use:
Cheswick Borough v. Bechman,
The use of the property which the ordinance protects, or “freezes”, is the use which was in existence at the time of the passage of the ordinance or the change of a use district
(Upper Darby Township Appeal,
To permit the use of this property as a gasoline service station, a vastly different use for the accomplishment of which the existing buildings would be demolished and a new building erected, is a clear violation of Section 10(c) of this ordinance. The grant of such permission could mean an almost indefinite continuance of a nonconforming use by periodical rebuilding of structures on the land which would be at complete variance with the spirit of a zoning ordinance, i.e., the gradual elimination of nonconforming use. 5 In upholding the refusal of the building committee to grant this permit to Hannas and Socony, the Board was clearly correct; in reversing the Board, the court below was in error.
Order reversed. Costs on Hannas and Socony.
Notes
These plans of course, would eliminate the dwelling house, thus ending any use of any part of the premises for residence purposes.
In the ease at bar no authorized public officer has ordered any structural alterations to the existing buildings for their safety.
Por the purpose of this appeal we take the position that the contemplated change in the use of this property from a used car business to a gasoline service station will
upgrade,
not
downgrade,
the property:
Suhy v. Zoning Board of Adjustment,
In Cole v. City of Battle Creek, supra (p. 468), the Court stated: “The language of this paragraph [very similar to the language of Section 10(c)], requires the conclusion that the structural alterations permitted are limited to those made in existing buildings.’' There is no language which permits the erection of new *312 nonconforming buildings or additions to existing nonconforming buildings.
In Peirce and Davis, supra, the language of the ordinances involved were very similar to the language of the instant ordinance as to nonconforming uses. In Pierce the validity of the ordinance was not raised; in Davis the validity of the ordinance was raised but not passed upon.
Persistent discordant uses should be reduced to conformity as speedily as justice will permit:
