Summary
Elgin requires builders to control water runoff and erosion during construction and demolition, and to protect adjoining property's footings, walls and roofs, under IRC § R101.4. A companion rule at § R101.5 requires a 6-foot barrier around excavations when the building official calls for one.
Section R101.4 Protection required, shall be created to read as follows: Adjoining public and private property shall be protected from damage during construction, remodeling and demolition work. Protection shall be provided for footings, foundations, party walls, chimneys, skylights and roofs. Provisions shall be made to control water runoff and erosion during construction or demolition activities. Section R101.5 Adjacent to excavations, shall be created to read as follows: Every excavation on a site shall be enclosed with a barrier not less than 6 feet (1829 mm) in height where required by the building official.

Full Breakdown
4, Protection required, which applies to one- and two-family dwelling construction, remodeling and demolition work across the city. It requires that adjoining public and private property be protected from damage, naming footings, foundations, party walls, chimneys, skylights and roofs as the features that must be protected, and it separately requires that provisions be made to control water runoff and erosion during construction or demolition activities. 5, Adjacent to excavations, requires every excavation on a site to be enclosed with a barrier at least 6 feet high wherever the building official determines one is required, protecting neighboring property and the public from an open excavation during a build.
36, adopted under Ord. No. 48. Because these sections were created rather than merely amended, they exist only in Elgin's local code text and are not found in the unmodified IRC, making them a genuinely local runoff and erosion control standard tied to every residential building or demolition permit the city issues.
Violations & Fines
Failing to control runoff and erosion during construction or demolition, or building without the required 6-foot excavation barrier once the building official calls for one, violates the adopted IRC as amended by § 16.36.020 and is enforced by the building official, who can issue a stop-work order. Violations are punished under Elgin's general penalty, § 1.20.020: $50 to $750 per offense, with each day of noncompliance treated as a separate violation.
