I think it unnecessary to here consider whether complainant is entitled to the relief sought for the protection and enforcement of a general building or development scheme, for I am convinced that complainant is entitled to enforce against defendants the express covenants made by defendants’ predecessor in title with complainant’s predecessor in title in an agreement dated May 12th, 1899.
On May 12th, 1899, while a suit was pending in this court by the .Absequan Hotel Company, complainant’s predecessor in title, against -James B. Reilly, defendants’ predecessor in title, and the common grantor of the respective parties to this present suit, which former suit was to prevent Reilly from erecting buildings at the very spot where the present defendants have, during the pendency of this suit, erected a building, a compromise settlement was made and reduced to writing and executed by the respective parties and acknowledged by them and duly recorded. By that instrument the complainant hotel company allowed the defendant to maintain the buildings then on the controverted twenty-feet, strip for a period of one year from that date, and defendant agreed to remove the buildings on one month’s notice after the expiration of one year. The agreement, after reciting, among other things, that defendant Reilly had theretofore covenanted with complainant hotel company that the land now in question should not have erected thereon any building nearer than twenty feet from the front property line of St. Charles Place, concluded as follows:
“It being expressly agreed and understood that said covenants and restrictions as hereinabove recited are binding in all things upon the parties hereto, their heirs and assigns, and upon the land apd premises hereinabove described.”
The terms of this agreement are clear and explicit. It imposes upon Reilly, as owner of the land then owned by him and *165noAAr owned by defendants, an obligation to refrain from the erection of any building in disregard of the twenty-feet building line for the protection of which a suit, was then pending, and defines the stipulation as binding on the respective parties and their heirs and assigns and upon tne land referred to. It was precisely that right for Avliich the suit thou pending Avas brought, and by reason of the engagements made by Reilly in that agreement the then pending suit against Beilly Avas discontinued and a concession made by the complainant, therein (the present complainant’s grantor), to the effect that for one year complainant would not disturb the buildings Avhich Avere then located in violation of the defined building line. The agreement is sealed and the consideration stated in the agreement is “one dollar and the discontinuance of said proceedings.” That Avas clearly a sufficient consideration to support the covenant aside from the consideration imported by the seals of the parties. But by reading the entire agreement it will adequately appear by the recitations that •the covenant there made by Beilly to preserve the tAvent3r-feet building line was a re-engagement on his part to faithfully perform an engagement of the same nature which he had thereto-? fore made Avith the complainant hotel company, or in behalf of complainant’s land, at the time he had conveyed to the complainant hotel company lands on the same street. These prior engagements of Beilly, as recited in the agreement, do not purport to be in the exact language contained in the prior .deed from Beilly to the complainant hotel company. But, .in the deed to the complainant hotel company, folloAving the covenant touching the twent3r-feet building line, the following language appears:
“It being the purpose of this restriction to preserve an open space for view and air of twenty feet in width between the northerly line of the land above described and the Atlantic ocean,”
and in a prior deed made to Wootton Beilly had expressly coaunanted to insert a coA enant protecting the building line in all subsequent deeds made by him. It thus appears that Avhile the deed to the complainant hotel company contained no clause Avherein Reilly expressly eoA7enanted to insert similar covenants in all subsequent deeds, it did contain a clause stating that the *166twenty-feet open strip was to extend to the ocean. The restatement of the original covenants in the agreement of 1899 may therefore be appropriately regarded as a statement of their substance as the parties originally intended and understood them, and they thus appear to be a reasonably accurate statement of them as they existed in the deed from Reilly to the complainant hotel company. If. any doubt could be said to have theretofore existed as to whether the clause m the deed from Reilly to the hotel company which declared the purpose of the restriction to be to preserve the open space twenty feet wide to the ocean was an engagement upon the part of Reilly to keep- it open, that doubt was fully removed by the terms of the agreement of 1899.
The present complainant is now tire owner of the land which was owned by the complainant hotel company in the former suit, this bill having been heretofore dismissed as to complainant Wootton. The present defendants are now the owners of the very land to which the agreement of 1899 related, and its record has afforded them with notice of its terms. It also appears that one of the deeds in the chain of title from Reilly to defendants contains the following: “Subject to- * * * such boardwalk and park easements and building restrictions as appear of record.” This recitation also charges defendants with notice of the covenants in the agreement of Reilly already referred to.
There-appears to be no doubt of the right of a vendee of land to enforce against his vendor a covenant of the vendor that he will not build upon his remaining land except in a manner specified in the covenant, providing the building restriction thus im-' posed is not of a nature to contravene principles of public policy. Brewer v. Marshall, 19 N. J. Eq. 537. Nor does it seem essential to the -enforcement of such a covenant that it be embodied in or form a part of a deed of conveyance from the covenantor to the covenantee. Kirkpatrick v. Peshine, 24 N. J. Eq. 206. And no satisfactory reason can be assigned why a mutual agreement between two property owners on a given street for the purpose of establishing or maintaining a building line wherein the parties engage to bind themselves and their land to the observance of the building line should not be enforceable in a court of *167equity against either at the instance of the other. And when such agreements are expressly made to hind the parties and their heirs and assigns the equitable right -to the enforcement of the agreement by a purchaser from one party against a purchaser from the other partjr with notice of-the agreement would necessarily exist. It is unnecessary to regal’d such covenants as creative of easements; the equitable right to enforce the covenant is transferable as a part of the land to which it is attached (Coudert v. Sayre, 46 N. J. Eq. 386, 393, 395) and may be enforced upon the equitable principle of preventing one having knowledge pf the just rights of another from defeating such rights. Brewer v. Marshall, 19 N. J. Eq. 537, 543; Nicoll v. Flenning, L. R. 19 Ch. Div. 258, 266.
There can be little, if any, difference in principle between a restrictive covenant made by a vendee for the benefit of remaining land of his vendor, and one made by a vendor touching his remaining land for the benefit of his vendee. Both are held to be enforceable by a purchaser of the land for the benefit of which ihe covenant has been made against a purchaser of the restricted land who is chargeable with notice of. the covenant. As to the former class see Coudert v. Sayre, 46 N. J. Eq. 386; DeGrey v. Monmouth Beach, 50 N. J. Eq. 329; Hayes v. Waverley and Passaic Railroad Co., 51 N. J. Eq. 345, 348; Roberts v. Scull, 58 N. J. Eq. 396; Hemsley v. Marlborough Hotel Co., 62 N. J. Eq. 164; S. C. affirmed, 63 N. J. Eq. 804; McNichol v. Townsend, 73 N. J. Eq. 276; Bowen v. Smith, 76 N. J. Eq. 456; Sailer v. Podolski, 82 N. J. Eq. 459. As to the latter class see Brewer v. Marshall, 19 N. J. Eq. 537; Coudert v. Sayre, supra (at p. 391); Kirkpatrick v. Peshine, 24 N. J. Eq. 206 (an agreement by a vendor with his vendee made after sale of the land); Leaver v. Gorman, 73 N. J. Eq. 129, 131; Hyman v. Tash, 71 Atl. Rep. 742, 744; Watertown v. Cowen, 4 Paige Ch. 510; Mann v. Stephens, 15 Sim. 377.
■ It is urged that, complainant has violated the covenant by at times placing screens under the porch of his building and thereby obstructing the view over the twenty-feet building line, and cannot, in'consequence, be heard to complain of defendants’ viola*168tion of the covenant. 1 am unable to find that the covenant has been violated by complainant. ■
An application of complainant for a preliminary injunction on the present bill was refused ; but in the opinion then filed it was stated that should defendants erect their proposed building on the restricted territory during the pendency of the suit, they would do so at their peril, and the bill could, in such event, command mandatory relief if sustained at final hearing. The building has, notwithstanding, been erected pending the suit, and I will, accordingly, advise a mandatory injunction for the removal of such parts of the building as have been erected within twenty feet of the property line of St. Charles Place. Only porches and bay windows constructed in accordance with the provisions of the restrictive covenant can be permitted within the restricted territory.
