California Civil Code > Civil Code §799.11. Improvements to Accommodate the Disabled
The ownership or management shall not prohibit a homeowner or resident from installing accommodations for the disabled on the home or the site, lot, or space on which the mobilehome is located, including, but not limited to, ramps or handrails on the outside of the home, as long as the installation of those facilities complies with code, as determined by an enforcement agency, and those facilities are installed pursuant to a permit, if required for the installation, issued by the enforcement agency. The management may require that the accommodations installed pursuant to this section be removed by the current homeowner at the time the mobilehome is removed from the park or pursuant to a written agreement between the current homeowner and the management prior to the completion of the resale of the mobilehome in place in the park. This section is not exclusive and shall not be construed to condition, affect, or supersede any other provision of law or regulation relating to accessibility or accommodation for the disabled.
