What efforts to resolve issues with park management, or to put them on notice, will be required before a homeowner can file a complaint with HCD under the Act?

None are legally required before a complaint is submitted, although homeowners are always encouraged to try and work out issues before engaging assistance.  Once a complaint is submitted and selected by HCD for enforcement, a notice will be sent by HCD informing both the complaining homeowner and the park owner/management that they have 25 days to try and informally resolve the complaint before referral to a local law office.
