California Building Code Review Targets Park Trailers and Mobile Home Regulations

During the recent Planning Commission meeting held on August 22, 2025, in Mariposa County, a significant discussion emerged regarding the regulation of park trailers and building codes. The conversation centered on the need for clarity and consistency in how these regulations are applied, particularly in relation to California's established building codes.

One key point raised was the suggestion to remove specific references to California building codes in favor of relying on the definitions provided by the California Department of Housing and Community Development (HCD). This change aims to streamline the regulatory process for park trailers, ensuring that the guidelines are straightforward and aligned with state law.

Commission members emphasized the importance of maintaining clear standards for plumbing and electrical services connected to these units. The discussion highlighted the necessity for these services to comply with approved standards, whether through public utilities or septic systems, which is already a requirement for mobile homes.

The proposed adjustments are intended to simplify the installation permit process for park trailers and recreational vehicles, making it easier for residents and developers to understand their obligations. The commission acknowledged the need for consistency across all documents related to these regulations, which will help avoid confusion and ensure compliance with state guidelines.

As the meeting concluded, the commission expressed a commitment to refining these regulations further, aiming to enhance clarity and support for the community's needs. This initiative reflects a broader goal of improving housing options and ensuring safety standards within Mariposa County.
