This is an action to recover damages for breaches of covenants with respect to repairing Eivington Street pier, No. 50, on the East river, contained in a lease in writing between the parties made on the 15th day of November, 1901, by which the plaintiff leased to the defendant the pier and the bulkhead between it and the Eivington Street pier north, No. 51, together with the new-made land in the rear of the bulkhead under the jurisdiction of the department of docks and ferries, for the period of ten years from the 1st day of December, 1901, for the annual rental of $2,100. There is no recital in the lease with respect to the condition of the pier at the time the lease was made; nor.does the lease contain the usual provision excepting ordinary wear and damage by the elements from the obliga- • tions of the tenant to make repairs. The tenant covenanted to “ put, keep and maintain the said wharf property and every part thereof, and the structures thereon or to be erected thereon, or any structures erected under the provisions of this lease, in good and sufficient repair and condition, and that all such repairs during said term shall be done at ” his sole cost, charge and expense.
*563In the next succeeding paragraph the tenant covenants “that he will not at any time make any claim that the said wharf property is not or was not at the time of the commencement of said term in suitable repair or condition for the uses and purposes of this lease.” It is further expressly provided that if the tenant should make default, and should neglect or refuse to make repairs as covenanted by him, for the period of ten days after notice, then the lease should be null and void, and the tenant would pay such damages as the landlord may have sustained, or at its option it might make the repairs and the tenant would pay the full cost and expense thereof on demand, and should have no claim for reduction of rent on account thereof; and it was mutually agreed “ that if by reason of total or partial destruction, through fire, floating ice, collision or the action of' the elements, the wharf property herein-before described shall require to be rebuilt, the same shall be so rebuilt under the direction of the board of docks, in like manner and similar to the wharf property destroyed, by and at the expense of the ” tenant “ and in accordance with plans and specifications submitted to and approved by the board of docks,” In the event of the failure of the tenant “ to perform, keep, do, or observe any or either of the covenants, agreements, promises, things, terms or conditions herein contained on ” his part, it was expressly provided that the landlord, by resolution of the board of docks, might, in its discretion, terminate the lease. The tenant covenanted and agreed that at the termination of the lease as therein provided, or • at the expiration of the term, the wharf property and structures “ shall then be well and sufficiently repaired and in good order and condition.” At the expiration of the period for which the lease was given the tenant surrendered possession.
This was an unshedded pier about 240 feet in length. The deck of the pier was about five feet above mean high water and about nine feet above mean low water, and consisted of planking, known as “sheathing,” three inches in thickness and twelve inches in width, bordered by a row of. timbers, known as “ backing logs,” twelve by twelve inches, and non mooring posts were placed at intervals along either side for the mooring of vessels. It was used for unloading and loading freight, *564which was hauled to and from, the pier by hundreds of trucks daily carrying six or seven-ton loads. After the tenant surrendered possession similar use was continued under the supervision of the department of docks until the month of October, 1912, when it was fenced off preparatory to reconstructing the pier under a contract which the city let to the New York Submarine Contracting Company, and the performance of that contract work occupied the period from October 6, 1912, until January 6 or 8, 1913.
The pier was built in the year 1888 at a cost of $16,049. Its width was not shown. About 200 supporting piles about sixty feet long were driven into the earth four or five feet apart in rows parallel with the shore and about ten feet apart. On the piles along the outer edge of the pier on either side were placed yellow pine timbers, twelve by twelve inches, known as “side caps,” and on these were placed timbers of the same material and dimensions, running crosswise of the pier, known as “cross caps,” and on the cross caps were placed timbers of the same material and dimensions, running lengthwise of the pier, known as “rangers,” some in single and some in double rows, forming nine rows in all, which constituted practically the floor beams of the pier. On the rangers yellow pine planking, four inches by eight inches, known as “decking,” was laid crosswise of the pier, and two or three inches apart, excepting where laid over “ chocking,” where they were closer; and on this was laid the “sheathing,” which has been described. What is known as “vertical sheathing” was placed on the outer end of the pier, and consisted of five by ten-inch timbers attached to the end of the pier in an upright position. In the construction of the pier “bracing” piles were used, and there was also bracing known as “A” bracing and “horizontal” bracing on the supporting piles, and bracing or wedging known as “chocks” or “chocking,” consisting of short timbers placed between the rangers and between the fender piles and under the mooring posts to strengthen their support. When the pier was originally built oak timbers eight inches by twelve inches and fourteen feet long were attached to the outer ends of each row of piles at the sides of the pier, extending from the top of the backing logs down to about two *565feet underwater, to serve as fenders; but at some time prior to the reconstruction work under said contract, additional piles were substituted for the oak timbers for fenders.
From the time the pier was constructed until the year 1890 the city maintained a dump on it. In the year 1890 the pier was leased to the defendant for five years, and it was leased to him again in 1897 for three years, the term expiring in April, 1900, but he continued to use it with the general public until the lease in question was made; and he testified that during this period from the expiration of his former lease until the making of the present lease, no repairs were made, and that he was under no obligation to make any.
The evidence shows that the life of sheathing is from one to four years, decking from ten to twelve years; backing logs from eight to ten years; vertical sheathing ten years; chocks on mooring posts twenty years; supporting and bracing piles from fifteen to twenty-five years; side caps twenty years; ends of cross caps fifteen years; bracing twenty years, and rangers from twenty to twenty-five years.
The further evidence presented by the plaintiff with respect to the condition of the pier relates to its condition in October, 1911, upwards of a month prior to the expiration of the lease, and to its condition when it was closed for repairs some ten months after the expiration of the lease. The plaintiff showed that the total cost of reconstruction was $12,033, and it claimed the right to recover the entire cost of the work which substantially constituted a rebuilding or reconstruction of' the pier, for according to the testimony of a civil engineer in the department of docks, the pier “was stripped of every thing practically down to the tops of the cross caps;” and the fender system, the chocks under the mooring posts, part of the cross caps, and all of the piles with the exception of seventy-five supporting piles and six or seven bracing piles were removed, and the piles not removed werer spliced. The testimony of this witness further tends to- show that owing to the worn and decayed condition of the material removed, only a small percentage of it was suitable for use in the reconstruction of the pier. In the reconstruction of the pier, the pile fender system was abandoned excepting at the outer comers, and the oak timber fender sys*566tem which was the original construction was adopted. There is no evidence tending to show the relative cost of construction according to the old system or according to the system thus adopted; but the evidence is open to the inference that the change in the fender system was made by the defendant, and if so, that is immaterial.
The evidence offered on the part of the plaintiff also tended to show separately the reasonable cost of many of the classes of items of reconstruction; but the case was submitted to the jury on the theory that the plaintiff was claiming the entire contract price of the work, and there was no request on the part of the plaintiff to have the jury instructed that it was entitled to recover the reasonable cost of the repairs which should have been, but were not, made by the defendant.
On the part of the defendant evidence was given tending to show that during his occupancy under the prior leases he maintained the pier in proper repair, and that while in possession under the lease in question, and in the year 1902, he reconstructed the fender system, backing logs and sheathing, and replaced defective decking and rangers; and that in 1907 he “ renewed the deck ” of the pier, and that otherwise during his occupancy he kept the pier in proper order and repair; but the repairs made by him did not extend to the substructure, and, with respect to that, evidence was given tending to show that its condition was not readily discoverable, and that it would be necessary to go under the pier in small boats and bore into the piles and timbers, or test them with a pike.
The court, during the progress of the trial, apparently overlooking, or failing to give effect to, the obligation of the tenant to put the pier in proper repair at the time he entered under the lease, repeatedly ruled that it was necessary for the city to show the condition of the pier at the commencement of the term and at the termination thereof, and that the damages recoverable were to be measured by the cost of placing the pier in as good condition as it was in at the commencement of the term. In the charge the court instructed the jury that it was the duty of the tenant to put and keep and maintain the pier and every part of it in good and sufficient order and repair, and to surrender it in that condition of repair, and stated that the *567duty was the same as if he leased a house under a covenant to turn it over at the expiration of the term in good order and repair, and that his duty would be to turn the house over in a condition practically the same as that in which he received it, but that there would be no duty to reconstruct it, and that if the work that was done practically constituted the construction of a new pier, then the plaintiff would not be entitled to recover, but that if the character of the work done by the plaintiff was such as to put the pier in good and sufficient repair, as required by the lease, then plaintiff was entitled to a verdict for such sum as it had fairly expended in putting the pier in that condition, taking into account the character of the construction and the nature of the material of which the pier was originally constructed. At the close of the charge, counsel for the plaintiff inquired whether the court intended by the charge to instruct the jury that there was no duty on the part of the tenant to reconstruct parts of the pier which were worn out. The court replied that the jury had not been so instructed, but merely that it was not the duty of the defendant to construct a new pier, and that it was left to the jury as a question of fact to determine whether it was the duty of the defendant to reconstruct parts that were worn out, and in that connection the court further charged as follows: “ He had to do anything that would be required to put, keep and maintain the property, and every part thereof, in good and sufficient order and condition, at his own cost and expense. His testimony is, and the testimony given on his behalf is, that he actually did do that; that at the time of the expiration of the term he left it in the same order and condition, or, at least, in as good order and condition, as that in which he got it. If he did that, then the burden which was imposed upon him has been actually met by him. If he did not do that, then, to the extent to which he failed to do it, and only to that extent, may the City hold him.” Thereupon counsel for defendant said: “ I understand you to say there was no duty to rebuild the pier, or to practically rebuild the pier,” to which the court replied: “ Yes, there was no duty of that kind.” Counsel for the plaintiff thereupon took an exception as follows: “ I respectfully except to that portion of your Honor’s charge.” We are of opinion that this *568exception should not he limited to the last preceding instruction given at the suggestion of counsel for the defendant to the effect that there was no duty on the defendant to rebuild or practically to rebuild the pier, but that it should be deemed an exception to the instruction immediately preceding that to the effect that the defendant discharged the burden imposed upon him if he left the pier in the same order and condition, or in as good order and condition, as that in which he found it at the commencement of the term. Manifestly that instruction was erroneous, for it relieved the defendant of his express obligation to put the pier in proper order and repair at the outset.
We think the case was tried-and submitted to the jury on another erroneous theory; namely, that the inquiry was whether the defendant was answerable to the plaintiff for the moneys expended by it in reconstructing the pier. The amount thus expended by the city was wholly immaterial, excepting in so far as it tended to show the reasonable cost of making the repairs which it was the duty of the defendant to make, and which he failed to make. It was immaterial whether the plaintiff reconstructed the pier, or what it did with the pier, after the expiration of the term. (Appleton v. Marx, 117 App. Div. 206; affd., 191 N. Y. 81; S. C., 16 L. R. A. [N. S.] 210 and note; Boardman v. Howard, 64 L. R. A. 667, note.) The learned court was right, I think, in ruling that the tenant was under no obligation to rebuild the pier, for the provisions of the lease do not show that the tenant’s covenants to repair contemplated rebuilding. His only covenant to rebuild was. in the event of the destruction of the pier by fire, floating ice, action of the elements, or accident, and with respect thereto the lease contains express provisions regulating the rebuilding which was to be according to plans and specifications submitted to and approved by the board of docks and under its direction. The repairs he was required to make were to be made on the existing structure and they were required to be made without plans or supervision. The city, to recover herein, must show a condition of disrepair of the pier which would have justified it in terminating the contract if the tenant failed to make the repairs during the contract period. His duty involved reconstruction work and replacements to a certain *569extent. It was his duty to replace decayed, worn out or damaged material on the surface or exterior of the pier, and on the interior and underneath where this was reasonably necessary and practicable, and where the work could be done without unduly depriving him of the beneficial use of the pier; but the covenants of the lease did not, I think, require him to suspend the use of the pier and remove the entire structure resting on the piles and remove or splice or fish-plate piles which were decayed above the water line, or to incur extraordinary expenditures in supporting the body of the pier in place and removing or splicing or fish-plating piles where that became generally necessary by reason of the age of the piles. In the case at bar, it appears that the average life of the piles had been passed or reached, and that it was necessary to remove most of them or to splice or fish-plate the upper ends of the majority of them which, according to the evidence, would require the removal of the entire body of the pier above them, and would constitute a rebuilding of the pier. In Lockrow v. Horgan (58 N. Y. 635) covenants by a tenant of a house “ to make all necessary repairs ” and to “keep the premises in tenantable order ” were construed in a memorandum opinion as requiring him to rebuild a leaning wall of the building, and that this was not excused by a subsequent clause requiring the tenant to surrender the'premises at the expiration of the term in as good condition as at .the commencement, necessary wear and tear and damage by the elements excepted, and that decision was followed on like facts in Bushwick Realty Co. v. Sanitary F. P. Co. (129 App. Div. 533); but the Court of Appeals in May v. Gillis (169 N. Y. 330) held that a lease obligating a tenant of a house to make “ all inside and outside repairs ” and to leave the demised premises in “as good state and condition as reasonable use and wear thereof will permit, damages by the elements excepted,” only required him to make ordinary and not extraordinary repairs; and that Lockrow v. Horgan (supra) must be deemed to have been distinctly overruled by Butler v. Kidder (87 N. Y. 98), if the covenants under review in the former were not distinguishable from those under review in the latter or then under review. The general rule is that in an action brought by a landlord after the expiration of a lease for *570a breach of covenants to keep and to leave a building or structure in good order and repair, the measure of damages is the amount it would cost at the expiration of the lease to put the building or structure in the condition in which the tenant should have left it. (Appleton v. Marx, 117 App. Div. 206; affd., 191 N. Y. 81; Lehmaier v. Jones, 100 App. Div. 495; Ducker v. Del Genovese, 93 id. 575; Wanamaker v. Butler Mfg. Co., 136 id. 265.) I am of opinion that it is now the general rule that a tenant who merely covenants to put and keep in repair is not obliged to rebuild where the rebuilding is not rendered necessary through his failure to perform his covenant to keep in repair, or through other fault on his part. (Butler v. Kidder, 87 N. Y. 98; Ducker v. Del Genovese, supra; Lehmaier v. Jones, supra; May v. Gillis, supra; Appleton v. Marx, supra; Herald Square Realty Co. v. Saks & Co., 215 N. Y. 427.) The burden is on the plaintiff in such case to show the repairs which the tenant should have made and failed to make, and the reasonable cost thereof. (Hawkins v. Ringler & Co., 47 App. Div. 262.) If the rebuilding of the pier at the expiration of the term was rendered necessary owing to the failure of the tenant to perform his duty to put and keep it in repair, as herein defined, which did not require him to rebuild it, then, of course, he would be liable for the entire cost of the work.
It follows that the judgment and order should be reversed and a new trial granted, with costs to appellant to" abide the event.
