delivered the opinion of the court.
William J. Smith, the appellant, as administrator of the estate of Mabel Victoria Cooper, deceased, commenced this suit against the appellee, James Morrow, for the benefit of the next of kin of the deceased, in the circuit court of Lake county, to recover damages *628resulting to the next of kin by the death of the deceased, which it is alleged was occasioned by the negligence of the appellee.
The appellee is the owner of a three-story tenement building, situated on Belvidere street in the City of Waukegan. The building contains, six apartments, two in each of the three stories, located on each side of the center of the building. For the use and convenience of the tenants, who occupy the apartments, porches were constructed in the rear and were built across the entire rear elevation of the building, and connected together as one structure. There is a separate porch for each apartment, and a center porch which contains the stairways which run from the ground floor to each story, and which was used in common by all the tenants, as a means of ingress and egress; and the center porch was under the control and supervision of appellee as landlord. The porches and stairways are all constructed of wood; and a banister also of wood was built along the outer edge of the porches of each of the stories of the building. This banister was about 3 feet high, and consisted of an upper and lower rail which were nailed to upright posts, and spindles were fastened in between the rails. The porches set apart for the tenants were roofed over, but the center porch had no roof and was therefore more exposed than the other porches to the deteriorating influences of the weather. Sophia Cooper was a tenant, and as such 'tenant occupied one of the apartments in the third story, with her daughter Mabel Victoria Cooper. Mabel was 25 years of age, and contributed to 1;he support of her mother. She had worked for a number of years for the Northwestern Railroad, and at the time of the accident which befell her she" was earning $100 a month. On the 14th of June, 1919, in the afternoon, Mabel and a girl friend, who was visiting her, were out on the porches and were walking near the banister on the center porch towards *629the head of the stairway. Mabel had her arm around her friend’s neck as they were walking along. Suddenly Mabel’s friend ducked and withdrew her head from Mabel’s arm; and during this incident Mabel happened to take hold of the upper railing of the banister, and the banister gave way, and she fell from the porch to the sidewalk below, and was fatally injured thereby, dying within a few moments after her fall.
The evidence tends to show that at the, time of the accident the ends of the rails which had been nailed to the posts were decayed, and the nails which had been used to fasten the rails to the posts had become so deteriorated by rust that their usefulness had been practically destroyed, and that the fastening for that reason gave way. The decay at the end of the rails, and the deteriorated condition of the nails, which constituted the defect in question, were not visible, however, nor discernible by superficial inspection.
There was a trial by jury, and at the close of the evidence for appellant the court directed a verdict for appellee; judgment was rendered on the verdict and this appeal is prosecuted from the judgment. The appellee contends that the defect in the fastening of the rails was a latent defect, of which the appellee had n'o knowledge or notice, and that therefore he cannot be charged with liability.
A latent defect is usually defined to be one that is not manifest, but hidden or concealed, and not visible or apparent. 25 Cyc. 161; Celluloid Mfg. Co. v. Cellonite Mfg. Co., 42 Fed. 900; Newell v. Turner, 9 Port. (Ala.) 420.
The defect in question was apparently of this character in that it was hidden from sight and ordinary observation. To come fully within the terms and scope of the definition, however, the defect should be hidden from knowledge as well as from sight.
The declaration in this case charges that the appellee *630had knowledge of the defect in question; also that by the exercise of reasonable care he could have ascertained the defect and repaired it, and that he neglected to exercise such care. “The law is well settled in this State that a landlord who rents different parts of a building to various tenants and retains control of the stairways, passageways, hallways and other methods of approach to the several portions of the building, for the common use of the tenants, has resting upon him an implied duty to use reasonable care to keep such places in a reasonably safe condition, and that he is liable for injuries which result to persons who are lawfully in such building, from a failure to perform such duty.” B. Shoninger Co. v. Mann, 219 Ill. 242.
It is a matter of common knowledge and experience that wood such as was used in the construction of the porches in question will .decay in course of time, and that nails will rust and disintegrate, especially when exposed continually to the effect of the elements. The length of time required to bring about a defective condition by decay or rust necessarily varies according to the particular conditions which prevail. The proof shows that this balustrade had been constructed and in use for a number of years, and- had been continually exposed to all 'kinds of weather, which naturally might cause the condition of decay and deterioration which was found. The clear inference may be drawn from the evidence that the appellee did nothing by which he could have ascertained the defective condition referred to which had developed in the course of time. Under these circumstances it was a question of fact for the jury whether the appellee was chargeable with notice or knowledge of the defective and insecure condition of the balustrade in question; and whether the appellee by the exercise of reasonable care could have ascertained or have had knowledge of the defect. Payne v. Irvin, 144 Ill. 482; *631 Fowler v. Crilly, 187 Ill. App. 399. We are of opinion, therefore, that under the averments of the declaration the questions of fact referred to should have been submitted to the jury and that the court erred in directing a verdict for the appellee. The judgment is therefore reversed and the cause remanded.
Reversed and remanded.
