This is an action to enforce, by way of injunction, a 40-foot setback restriction contained in the defendant’s title deeds. The restrictions are local and apply chiefly, if not exclusively, to the particular block where the defendants’ property is located. They are contained in a title deed of the defendants’ predecessor in title and were brought into the defendants’ deeds by way of general recital. When the defendants began their building they were of the impression that the setback limit was 30 feet, and, upon that idea, they located their building, made excavations, erected the frame work and roofed the building before they actually knew that the setback restriction called for 40 feet instead of 30 feet. The ordinance setback limit was 30 feet and the first complaint was made by the adjoining property owner, to the village officers. But, as there was no violation of the village law, the matter was dropped so far as the village was concerned. The adjoining property owner, however, notified the Boulevard Company of the violation of the building restrictions and the Company, in an effort to adjust matters, sought to have all interested parties agree to a 30 foot setback in lieu of the 40 foot setback provision of the deeds. Several interested parties were consulted, and agreed, to make the change, but the adjoining owner, Mrs. Glassbum, refused to make the concession and insisted upon the enforcement, by the Boulevard Co., of the restriction. So far as this action is concerned, looking through forms as a Court of Equity always does, Mrs. Glassburn is the real party in interest and is the moving force behind the prosecution.
It appears that something like $7,000 was expended by the defendants, in the erection of the two houses involved, before notice was given them, by anyone, that there would be an effort to enforce the setback restrictions. Inasmuch as the party principally interested lived next door, this would give rise to the presumption of lack of vigilance. Equity acts, especially in cases of this kind, on behalf of those who are vigilant and who assert their rights diligently so as to protect the opposite party from loss.
A still more significant circumstance is the fact that Mrs. Glassbum has violated the building restriction' and that neither she nor the *21Boulevard Co. are making any effort to enforce the restriction, as to her. Mrs. Glass-burn’s title deeds contain exactly the same restriction and yet she had constructed, and is maintaining, a part of her building, which she calls a sun porch, which extends a considerable aistance within the restriction area. This so called porch is, according to the evidence, an enclosed room.
This suit is being maintained upon the demand of Mrs. Glassburn and, in her interest, lacks equity for the reason that she is the first violator of the provision she now seeks to enforce. Under the circumstances of the present case we are of opinion that the plaintiff is not entitled to a decree and that the petition should be dismissed.
