This action was brought to restrain the erection of a dwelling house which, it was alleged, defendant was constructing in violation of a covenant contained in his deed. The common source of title of both parties is J. Henry Hentz, who, in September, 1888, conveyed a tract of land including the property in question to the defendant John H. Murphy, Richard M. Winfield, and Edward' J. Lucas. The deed from Hentz contained a covenant that “neither the parties of the second part nor their heirs or assigns shall or will at any time hereafter * * * erect any dwelling or other building within thirty feet of a front line.” Thereafter, Winfield and Lucas, by quitclaim deed, conveyed the property to Murphy, who on December 5,1890; conveyed to plaintiff lots described on a map of said tract as Nos. 86 and 87, and said deed contained a covenant on the part of the plaintiff similar to that contained in the Hentz deed. The map referred to in plaintiff’s deed was made after the deed from Hentz, and it designated thereon Summit avenue as a street. Summit avenue was subsequently opened, and plaintiff’s and defendants’ lots fronted thereon. The plaintiff’s was the first house erected on the street. The front wall of her house was placed 29.7 feet from the front line of the lot, and the piazza and steps were wholly within the 30-foot line. The front wall of the defendants* house is 30 feet from the front line of the lot, but there is a bay window which projects 3£ feet within the 30-foot line, and the piazzas and steps project further from the house than the piazza and steps on plaintiff’s house. Four other houses have been built on the same side of Summit avenue as the plaintiff’s house, all upon lots included within the property conveyed by the Hentz deed, and it was conceded by the plaintiff that all of the piazzas and all of the steps on the said houses were built within the 30-foot line of the lots.
It is the claim of the appellant that the construction of the bay window on defendants’ house was a violation of the covenant con*1131tained in the Hentz deed. If the decision of this appeal depended upon the determination of the question whether the bay window was a part of the building, and therefore within the restriction of the deed, I should be inclined to answer it in the affirmative. But the case does not call for a decision of that question. The parties have given a practical construction to the covenant in the erection of their several dwellings. All piazzas and steps have been placed within the 30-foot line, and, as I understand the testimony, at least three houses besides the defendants’ have bay windows which are within said line. While that fact is not expressly stated by any witness, it appears to have been assumed throughout the trial. It is so alleged in the answer as to the houses of Low, Lucas, and Malle, and the distance from the front line of the lot stated as to each. The defendant Murphy testified as follows: “I have measured the bay windows of the various houses on that block. They are all built within 30 front feet of the lots in every instance * * *. You can sit in the-bay window of Mr. Low’s house and see the front windows of the plaintiff’s house.” On cross-examination he was asked by the plaintiff’s counsel to state how many feet and inches the bay windows of Low’s and Lucas’ houses extended into the 30-foot, space. The witness Edward J. Lucas testified: “The piazza of every house on that block to a certain extent interferes with the view of the other houses. * * * The same thing applied to each and every bay window, to a certain extent” To the same effect is the testimony of the witness Tier. The plaintiff introduced no evidence to show that there were not bay windows on the other houses on the block, or that they were not constructed within the 30-foot space, and the testimony I have quoted stands uncontradicted. These facts, we think, preclude the plaintiff from enforcing the covenant against the defendant. She must either be deemed to have acquiesced in the construction of the covenant,—that it applied only to the front wall of the main building and did not restrict the construction of piazzas and bay windows within the 30-foot space,—or else, having acquiesced in repeated violations of the covenant, she is not now entitled to enjoin a person who acts upon the assumption that the restrictions are no longer to be observed. The rule is well settled that a person who seeks to enforce a covenant of this character must suffer no such breach of the stipulation as will frustrate all the benefit that would otherwise accrue to the other parties to the agreement.
It is unnecessary to consider the other questions discussed by the counsel, as, for the reasons above stated, we are of the opinion that the judgment must be affirmed.
