Add the following new section to IBC Section 1608 Snow Loads.

1608.2 Structural Loads.

When a new building is to be constructed or an existing building extended to a greater height than an existing adjoining building, a determination of structural integrity of the roof of the adjoining building s hall be made regarding the snow loads in accordance with Section 1608.0 SNOW LOADS. The person intending to cause the construction or building height extension shall deliver written notice of intent to the owner of the potentially affected building. The notice shall request license to enter the potentially affected building to inspect and determine the existing building's capacity to sustain additional imposed snow drift load. The person causing such construction shall be liable and shall at their own expense preserve, protect and, if necessary, reconstruct those portions of the adjacent building affected by this construction. If the owner of the adjacent building refuses to allow inspection, protection or reconstruction as may be required, the person causing such new construction or building height extension shall notify, in writing, both the Building Official and the owner of the adjacent property. Such notification shall identify that the responsibility of providing inspection, protection or reconstruction to the adjacent building has become the exclusive responsibility of the owner of the adjacent property.

1609.3 Basic Wind Speed.

The basic wind speed, in mph, shall be determined by Table 1608.1.

Delete all IBC Figures 1609 and substitute Rhode Island Wind Speed Map Figure 1609 and Figure 1609 (A), and Rhode Island frost protection figure 1609 (B)
