Summary
Carlsbad has no citywide rent-control ordinance, but Municipal Code Section 21.37.120(D) caps rent increases for one year after a mobile home park converts to resident ownership: any increase levied during that year cannot exceed the park's average annual rent increase over the prior three years.
"Conversion" means a use of the mobile home park for a purpose other than the rental, or the holding out for rent, of two or more mobile home sites to accommodate mobile homes used for human habitation. ... Following recordation of a certificate of compliance or conditional certificate of compliance, owners/tenants of mobile homes on any unpurchased remaining interest shall not be economically displaced for a period of one year from the date of recordation. A rent increase may be levied during this year provided the increase is equal to or less than the average annual rent increase levied during the previous three years.

Full Breakdown
120(A). 5. 56(f) has been or will be given, that each tenant has been offered an exclusive right to purchase their site on the same or better terms offered to the public for at least 180 days after the subdivision public report issues, and that the conversion is consistent with the general plan and housing element. 120(D): once a certificate of compliance records, owners and tenants on any unpurchased remaining interest cannot be economically displaced for one year, and any rent increase levied during that year is capped at the park's own average annual rent increase over the preceding three years.
120(F) additionally requires CC&Rs for any conversion to be approved by the City Planner before the final map and to provide for periodic maintenance of the exteriors of the mobile homes, and those CC&Rs cannot be altered or dissolved without written city approval.
Violations & Fines
A conversion permit issued in violation of Section 21.37.120's rent-cap or notice findings can be challenged, and the City Council can withhold or condition future approvals on the owner's compliance. General code enforcement under Chapter 1.08 applies to violations of the permit itself: most violations are chargeable as an infraction, though the City Attorney may instead charge a misdemeanor punishable by a fine up to $1,000, up to six months in county jail, or both, with each day of a continuing violation treated as a separate offense.
