Anyone wishing to alter any systems of a mobilehome must obtain approval from which department?

Obtaining approval from the Department of Housing and Community Development is necessary for anyone wishing to alter any systems of a mobilehome. This department is responsible for overseeing the construction, alteration, and maintenance standards for manufactured homes in California. It ensures that any modifications comply with state regulations regarding safety, health, and general welfare.

In contexts where modifications are made to essential systems—such as plumbing, electrical, or structural—approval from this specific department is critical to ensure that the changes adhere to the state’s building codes and safety regulations. This helps in maintaining the integrity of the mobilehome and protects the occupants.

While other departments may have roles in safety or environmental concerns, they do not specifically focus on the approval of changes to mobilehome systems as required under state law. Hence, the most relevant authority for this matter is indeed the Department of Housing and Community Development.
