According to an American Law Report, it is generally the rule that the owner or occupant of a property touching a public sidewalk does not, solely by reason of being the owner, owe to the public a duty to keep the sidewalk in safe condition. This rule of nonliability is not affected by a statute or ordinance requiring an abutter to construct or maintain an adjoining sidewalk, unless there is an express, contrary provision.
However, the abutter will be liable for injuries resulting from a defective or dangerous condition that is created by his or her own acts, which constitutes negligence or a nuisance under the circumstances. For example, an abutter may be liable for injuries resulting from negligent construction, alteration, or repair of the sidewalk, even though these acts in and of themselves do not create liability.
The courts have usually considered compliance with the requirements of a statute regulating the construction of sidewalks. In a number of cases, knowledge or notice of the defect is a factor for liability, although the courts in many other cases have not treated this issue, given the fact that knowledge or notice of a defect on a sidewalk, as well as its direct cause, is difficult to ascertain.
