702 and 703 Most municipalities do not inspect interior or exterior wall coverings. This is a true statement. Counties do not enforce many provisions of the code. This is one of those areas. The law says that the builder is responsible for meting all the provisions of the code.
All wall coverings have strict requirements, for installation.
These requirements are either outlines by code or by the manufacturer. Exterior wallcoverings should be installed properly to function properly. And to make things worse, improperly installed items may, by nature of the installation, have their warranties voided. Patio decks that are not installed properly. Posts that are not anchored.
