In December 2017, the California Department of Building and Safety (CalDBS) released its Residential Metal Building Code (RMBC).
The RMBC is the latest update of the Residential Metal Construction Code, which was enacted in 2000 and updated in 2008.
The RMBA requires that residential metal structures comply with all building codes in California, and is intended to address the concerns raised by residential metal workers and contractors who have expressed concerns about safety and health hazards.
The new RMBC provides for more stringent compliance requirements, and allows for building owners to apply for exemptions from compliance requirements if their metal structure meets certain building codes.
For example, the RMBC allows for an exemption if the structure meets a code requirement for fire sprinklers and fire sprinkler control systems that does not include an electrical system, a building code that includes a requirement for the construction of a fire suppression system, or a code that requires the installation of a water-supply system.
The state’s code also includes provisions for the installation and operation of an approved fire suppression and water-main system.
In the past, the state’s building codes have been implemented inconsistently, with building owners receiving exemptions only in limited circumstances.
For instance, in 2015, a builder of a commercial building was exempted from complying with the Residential Building Code due to the structure’s size.
This was a case of “compliance with the requirements but not the intent,” according to the state.
The builder had a structural flaw in the exterior that allowed water to seep through cracks in the foundation, creating a cavity for the fire to enter, and the fire spread to other buildings.
A similar case occurred in 2013, when a developer of a residential structure applied for a permit to construct a water mains system.
This required the developer to construct the structure in compliance with the code, and install a water supply system.
A 2015 lawsuit filed by a construction contractor against a building owner in Southern California found that the permit application for the water maining system was not in compliance of the RMBA.
In a ruling issued in December 2017 in that case, the court determined that the application for a water distribution system in violation of the building code was not an exemption and found that, because the building did not comply with the RMBS, the developer would have to pay the building owner damages.
The ruling stated that the developer had not complied with the building’s code, or with any applicable code requirements, including the Residential Fire Code, and therefore was liable for the violations that occurred.

CalDBS officials said that the 2017 Residential Metal Code was the last major revision of the code.
The Department of Buildings and Safety said that “the RMBC was intended to update the Residential Construction Code in order to address some of the issues raised by the Residential Mechanical Engineers and Contractors of California (RMEC), and to protect the safety and welfare of the residents of the State of California.”
According to the State’s Building Code, a residential building must comply with building codes, including those related to the installation, use, and occupancy of sprinklers, fire suppression systems, and water distribution systems.
The California Building Code also requires that a building be designed and constructed in accordance with building and code regulations.
In addition, the Residential Residential Metal Buildings Code (RSMBC) requires that the building comply with a minimum of 30 building codes and fire codes, as well as with a fire code that prohibits the use of non-combustible materials, such as metal and plastic materials, in residential buildings.
CalPERS (California’s Building and Equipment Recycling Commission) regulates residential buildings and property owners who use residential metal construction in the state and provides a comprehensive list of approved materials for residential buildings as well.
