Prior to December 1, 1893, the plaintiff and de: fendant-were engaged as copartners in the city of Syracuse in carrying on the business' of dealing in stoves,.furnaces and other things. Hpon said day the plaintiff proposed to. the defendant a plan for. the dissolution of said copartnership and for the division of its 'assets, which was ■ subsequently accepted by the latter, and upon January 30, 1894, formally agreed upon by-the parties. By this arrangement between them, amongst other things,- plaintiff was to pay to defendant several thousand dollars in addition to certain firm real estafe which the latter was to take. In consideration of this the plaintiff was to take the business assets of the old firm including its stock in trade, and was to have a lease of the property which furnishes the basis for the present dispute between them, and which was described in the agreement ás “ The rear of the Hauman property and the Eeis property now used by the copartnership.” Upon January 31, 1894, a formal lease by defendant to plaintiff was made by which was leased for the term of five years at the annual rental' of $300 the premises in question here and which were described in the lease as “ That portion of the rear of the ETauman and theLReis property now or formerly used by the firm of Hessler & Schafer.” Said lease also contains two clauses which have- become of special importance in this action. One of .these clauses was to the effect that the lessor (defendant) was “ To keep the roof, conductors, overflows, wash pipes and sewers in good and suitable condition for the safe use by second party of said premises.” The other clause was to the effect that plaintiff, the lessee, would permit defendant as lessor tó “ enter said premises at all reasonable hours to examine or make such repairs and alterations therein as . shall be necessary, or as he may consider necessary for the preservation or improvement thereof.” '
*647The premises leased, consisted of a one-story building, suitable and used for the purposes of a store, etc., which fronted upon Butternut street. The roof of said building was of tar and gravel and of substantially the same level throughout. A stairway by the side of the store gave access to such roof from the street. As bearing on the rights of the parties and to aid in the interpretation of that clause in the lease which described the property demised as that “ Sow or formerly used by the firm of Hessler & Schafer,” as well as of other clauses in the lease, considerable evidence was given in regard to the use or nonuse of this flat roof by such co-partnership for the purpose of storing empty boxes and barrels in connection with their business, and I reach the conclusion that the roofs of both the Eeis and Bauman property were more or less so used by said copartners. In fact, there is not much dispute upon this question, for it is conceded by defendant that such articles were stored upon the roof of the Bauman property and carried down over the Eeis property through this stairway in question. It is true, it is claimed by defendant that they were carried up to such roof by another stairway, but that stairway is not in any way now leased to or controlled by plaintiff and, therefore, there is no way for him to obtain access to and use the Bauman roof without being able to have access to and use the. Eeis roof. The clause- above quoted that defendant was. to keep the roof in suitable condition for the use by plaintiff and which was written and not printed in the lease, would also seem to indicate some other expected use of it than for the ordinary purposes of protection.
After the dissolution aforesaid and after plaintiff had entered into possession and occupation of the leased premises and commenced the carrying on therein of the business of selling stoves, furnaces, etc., defendant commenced to erect on top of the building so leased as aforesaid two additional stories. As above stated, a preliminary injunction was granted restraining such construction, but that being subsequently vacated upon the giving of the undertaking provided, defendant continued to complete the construction and erection of such two stories. Amongst others, the temporary effect of such construction was to more or less damage by rain and exposure plaintiff’s goods and to interfere with the conduct of his business, the arrangement of his signs, etc. The permanent effect of such construction has been, amongst other things, to prevent the use by plaint'ff cf .he roof above mentioned for storage purposesand to place directly above and over the store and story occupied by him *648two stories of a building which are more or less covered with defendant’s signs and in which he is conducting a rival business, and to and from which somewhat bulky and heavy goods are moved up and down in front of plaintiff’s premises. There have resulted also some minor changes in the construction of the store occupied, by plaintiff, such as erecting a post near his door, putting in girders, etc!
The legal question presented, of course, is whether defendant had the right to enter upon such premises after they were so leased by him to plaintiff as aforesaid and to erect, these additional stories. There is no evidence to indicate that if he: had such right at all he has unduly or negligently damaged or' interfered with plaintiff’s property and business. In fact there is little dispute between the parties that the damages,, temporary and permanent, which plaintiff has suffered necessarily flowed and resulted from the acts of defendant, and upon that account perhaps the contention is all the more strongly made by plaintiff that he did not have the right to perform them. The question of whether he did or not is to be-determined substantially by the construction of the claiise already quoted from the lease, whereby it is provided that the lessor may enter the premises leased to make such repairs and “alterations therein as shall be necessary or as he may consider ■ important for the preservation or improvement thereof.” It is not claimed that the acts performed by defendant were to any degree, at least, repairs or alterations necessary or important for the preservation of the property. The contention, therefore, is narrowed down still more to a construction of the words allowing the landlord to go upon said premises for the purpose of making such “ alterations therein * * * as he may consider important for * * * the improvement"thereof.” Defendant claims that these words did permit him to perform the acts complained of by plaintiff; that under them there was substantially no limit to the changes which he might make in 'the demised premises which, according to his judgment, improved them, so long only as he acted and exercised his judgment in good faith. I do not find myself able to agree with this contention. I think that the entire clause m question had for its general purpose the keeping of the premises in good repair and in good condition; that when it permitted defendant to make repairs and any alterations “ therein which he might consider important for the improvement thereof,” it meant to give him the right to make such changes in the minor detail of the premises and buildings as would better the condition thereof, having in. mind the con*649dition and purposes and object of the premises as they were leased, and without substantially altering or changing the construction and condition thereof., I do not believe that the clause and words quoted gave to the defendant the right upon the building which he leased as a basis and first story to put up a substantially new and different structure and building which would substantially change the condition and uses and advantages of the building which he had leased, even though in his judgment when it was completed the new building would be an improvement over the old one. Upon defendant’s construction of this clause, if he had leased to' plaintiff a house and lot to be used strictly for dwelling purposes, and if through conditions existing at or subsequent to the time of the lease it would be an improvement to the premises in a pecuniary or revenue producing way to erect in the front yard or even add on to the house a business block, he would have the right to do it. That would be perhaps a little more extreme but not much more so than the acts which have been performed in this case. Plaintiff, as stated above, as part of the dissolution of the former copartnership with defendant, took the business of the firm and leased the premises in question for the purpose of there carrying on such business. Defendant has constructed on top of the premises which he leased an entirely new structure in which he is carrying on a rival business necessarily to the detriment of and interference with plaintiff’s business. The new structure is no improvement to the premises leased by plaintiff and for which he is paying defendant rent. It is simply an addition to those premises for the benefit of defendant .and at the expense of plaintiff’s rights. If defendant’s contention is correct that this may be done, there is no limit to what may be done in the way of changing and altering the building leased, or in fact removing it altogether.
It is true, as claimed by defendant’s counsel, that if plaintiff has voluntarily made a lease containing a clause which permits defendant to do as he has done, he cannot complain, and should not be relieved of the consequences of his contract simply because it may be a hard one. But in interpreting the lease in question and thereby determining whether plaintiff has made such a contract as is claimed by defendant, it is not only the right but the duty of the court to give such reasonable construction when possible as will secure a fair measure of justice between the parties to the contract and not place one of them largely or wholly at the mercy of the other. Russell v. Allerton, 108 N. Y. 288.
*650Beaching the conclusion, therefore, that the construction claimed by plaintiff and not that urged by defendant is the- proper one to place upon the clause in controversy, the question is reached what form of judgment and manner of relief shall be given?
It is insisted by plaintiff that in addition to compelling defendant to respond in damages for injuries already suffered, the court should compel him to tear down the new structure and to restore the premises to the condition in which they originally were. Defendant, upon the. other - hand, says that by the order vacating the preliminary injunction and allowing the building to proceed and the undertaking given ■ thereunder to cover any damages which plaintiff might suffer for defendant’s acts which should be held unauthorized, the necessity for this present action or any relief thereunder -has passed and that plaintiff has virtually been relegated and restricted to an action at law upon the. bond to recover any proper damages. ■ ■
Deither of the courses suggested seems to be quite the one to wholly .pursue in this case. After the making, of the order and the •giving of the undertaking in question, plaintiff undoubtedly might have discontinued and abandoned this action and resorted to one upon the undertaking, but he was not obliged to do so. The order and undertaking together simply in effect provided that defendant might go ahead with the construction of his building, and insured to plaintiff the recovery of any damages which he might suffer by reason of such procedure before a final judgment should be rendered fixing the rights of the parties and awarding the proper relief. As appears very.clearly by the decision of the .appellate court, it was not intended by this preliminary order to finally determine the rights.of the parties or to limit the court in its .final decision and determination. There, is probably no doubt, therefore, that this court could now render a judgment compelling the defendant to pull down the new stories and to restore the building as nearly as possible to its original form. In mew, however, of the fact that the court, by its order, has allowed him to complete the building and has made provision for his responding for any damage caused thereby, it would seem rather inequitable that the court should now compel him to pull down a building which he has thus been allowed to put up, and that justice would be better subserved- by allowing the building to stand and by. restricting the mandatory and prohibitory powers of the court to restoring such details of the original construction as can easily be replaced upon-the one hand-, and upon the other, to preventing such use of the new building as will be *651materially injurious to plaintiff. This end will be secured by providing in the usual form for a reference to ascertain the damages which plaintiff has suffered or will before the expiration of his lease suffer from the construction complained of; by further providing that defendant shall restore as nearly as possible the plaintiff’s signs, and that he shall remove and efface his own signs from the building and that the new portion shall not henceforth be used by defendant for the conduct and prosecution of his present business or for any other business, use or occupation which will materially interfere with plaintiff’s enjoyment of the premises leased by him.
Ordered accordingly.
