The exception here is to an order sustaining a general demurrer to a petition seeking injunctive relief. This is a case involving the enforcement of a restrictive covenant by the *624purchasers of lots in a real-estate subdivision as to the use of the lots by the owner of the unsold lots in the subdivision.
The petition states the following case: The defendant Waldrop filed and had recorded in the office of the Clerk of Clayton County Superior Court a document which recited that he was the owner of certain specified lands in Clayton County; that, in order to protect the purchasers of the property, “the following restrictions are hereby set up and shall apply to all sales of land by Manse Waldrop when said restrictions are specifically referred to in deeds from Manse Waldrop to purchaser.” (Italics ours). One of the restrictions being “the property herein conveyed shall not be used otherwise than for residential purposes . . . No apartment . . . shall be erected or maintained thereon.” Some of the plaintiffs purchased their property from the defendant, and others from his successors in title. All their deeds specially recited that the lots were sold subject to the recorded restrictive covenant and wez’e part of the lands recited therein. The defendant has caused a portion of the lands which he has not sold to be zoned for the erection of multi-unit apartments, and is preparing to use such lands by building apartments thereon, and thereby violate the restrictive covenant, to the damage and injury of the plaintiffs.
Where the owner of land adopts a genez’al scheme of dividing his land into lots for the purpose of selling them under express restrictions without reservations or limitations as to the use of the lots, and the restrictive covenants are for the benefit of the land retained, such a covenazzt as well as the lots sold mutually applies to all parties inter sese. However’, where the owner subdivides his land into lots, and the restrictions imposed by him on the use of the lots are limited only to those lots where the deeds to purchasers specifically incorporate the restrictions, and are not expressly made applicable to all lands in the subdivision, to be sold or retained, such restrictions would apply to the unsold lots of the owner only by implication. In such a situation the restrictive clause must be construed in the light of' the other facts of the record and intention of the parties. Limitations or restrictions as to the use of property by the owner are not favored and must be strictly construed. See Randall v. *625Atlanta Advertising Service, 159 Ga. 217 (125 S. E. 462); Campbell v. Empire Land Co., 163 Ga. 815 (137 S. E. 240); Thompson v. Glenwood Community Club, 191 Ga. 196 (12 S. E. 2d 623); Wardlaw v. Southern Ry. Co., 199 Ga. 97 (2) (33 S. E. 2d 304); Allen v. City of Detroit, 167 Mich. 464 (133 N. W. 317, 36 L. R. A. (NS) 890).
In the instant case the restrictions imposed by the owner on the lots he was selling as to the use of lots for residential purposes, and forbidding the erection and maintenance of an apartment, applied only to those lots sold by the owner where the deed to a purchaser specifically referred to the restrictive covenant. The owner thereby reserved the right to sell lots and make deeds not specifically incorporating the covenant thereto. Since it clearly appears that it was the intent of the defendant that the restrictions would apply only where there was a sale of a lot and the restrictions were specifically incorporated in the deed to the purchaser, he impliedly retained the right to use the unsold lots for puiposes other than a residential use and could erect an apartment on a portion of the unsold property.
The plaintiff, however, insists that, in view of the allegations in the amendment to the petition — “That the said restrictions as above set out were placed upon the land in order to sell lots therein to better advantage and to secure better prices and intended to and did, with respect to‘ the said land, establish a general building scheme and development plan, and thereby induced plaintiffs and many persons in the subdivision to purchase the lots therein, and that plaintiffs and others to whom lots were sold bought upon the faith and representations from the defendant that restrictions would be carried out as to the entire tract. That the said property of defendant on which he desires to construct apartment houses lies in and is part of the said property described in said restrictive covenant, and though not conveyed, is subject to the same restrictions as other property conveyed by the defendant to plaintiffs and others, it being the clear intent of the said covenant to protect all lots in the said property”— the defendant is estopped from asserting that the restrictions do not apply to lots retained by him.
With this contention we can not agree. At the time the plain*626tiffs or their predecessors in title bought their lots, the restrictive provisions were of public record and they had either actual or constructive notice of them. It is essential to the doctrine of estoppel in pais that the party claiming to have been influenced by the conduct, representation, or declarations of the vendor to purchase real estate was himself, not only destitute of knowledge of the true state of the title, but also of a convenient and available means of acquiring such knowledge. The condition of the title in the case at bar was known to the plaintiffs or they had the means of ascertaining the truth at the time they purchased their lots. See Elliott v. Keith, 102 Ga. 117 (29 S. E. 155); Carter v. Copeland, 147 Ga. 417 (94 S. E. 225); Bennett v. Davis, 201 Ga. 58 (39 S. E. 2d 3).
The court did not err in sustaining the general demurrer and dismissing the petition.
Judgment affirmed.
All the Justices concur, ■except Duckworth, C. J., and Head, P. J., who dissent.
