This law section mandates that the department create rules to define specific building standards, which need to align with recognized industry codes like the International Building Code and others listed. These standards are subject to change as the respective organizations update their codes.

Additionally, every city and county must report their wind and snow load requirements annually if they differ from state standards, allowing the department to inform factory-built housing manufacturers.

The department also has the authority to adopt other necessary rules and regulations to ensure compliance, prioritizing this part in case of conflicts with other housing regulations.

This law states that any rules and regulations related to foam building systems, as outlined in Section 17920.9 and the State Building Standards Code, apply to the sale, offer for sale, or use of these systems in factory-built housing. If foam building systems are used as a component in building such housing, they must comply with these standards and rules.

This law requires the department to ensure that factory-built housing follows all related building standards and regulations, except for specific exceptions listed in other sections.

This law allows city or county governments to take charge of inspecting factory-built housing within their areas if they choose to do so and are certified to handle the inspections. If a city or county decides to conduct these inspections, they can create a local ordinance to set up an inspection fee to cover the costs.

If there is no certified local inspection agency available, the department is responsible for inspecting factory-built housing directly where it is being manufactured.

This law states that the department must set regulations to determine which agencies can approve plans and specifications for factory-built housing. These agency approvals are treated the same as if the department had approved them directly. The regulations also need to make sure there's no conflict of interest between the manufacturers and the design approval agencies. Plus, the department will oversee how well these agencies are performing their duties.

This law allows the department to set rules on how quality assurance agencies can become qualified or disqualified for inspecting factory-built housing manufacturers. These agencies work under the department's supervision and can use the department's powers for inspections. The regulations must ensure there's no conflict of interest between manufacturers and these agencies, and the department will oversee the agencies' performance.

This section of the law requires local enforcement agencies to oversee and inspect the installation of factory-built housing to ensure it meets specific building standards set by the state. The law allows these agencies to charge a fee for such inspections, but they must establish this fee through a local ordinance. The housing must comply with both the State Building Standards Code, as related to factory-built housing, and additional specific requirements starting from Section 17910, all while taking Section 19990 into account.

This law states that local governments in California have the power to set their own rules for things like zoning, building setbacks, snow loads, wind pressure, and fire risk areas, along with design and aesthetic considerations. Even so, if these rules affect factory-built housing, they must be pretty similar to what's required for regular houses of the same size.
