Welcome to the Department of Housing (DOH). Within the DOH site, you would find what will be considered as standard for new constructions, or renovations. This will be in the form of new laws, and new standards. These new standards are intended to provide a simpler and safer design of the residence. It is also understood that houses are not apartments, and therefore will require different rules. However, every home has standards that would be required, and some that would be recommended. However, in all case, all obsolete infrastructure is required to be removed. One example will be to replace copper pipes with flex PEX pipes, and replacing gas with electric.
