Summary
Carlsbad grants density bonuses to housing developments that set aside very-low, low, or moderate income units under Chapter 21.86, implementing State Density Bonus Law (Gov. Code 65915). In the coastal zone, bonus projects must still satisfy the certified Local Coastal Program's resource-protection and public-access rules.
A housing development as defined in State Density Bonus Law shall be eligible for a density bonus and other regulatory incentives that are provided by State Density Bonus Law when the applicant seeks and agrees to provide very-low, low or moderate income housing units, or units intended to serve seniors, transitional foster youth, disabled veterans, homeless persons, and lower income students in the threshold amounts specified in State Density Bonus Law. ... Development within the coastal zone that is granted a density bonus, incentive(s), waiver(s), parking reduction(s), or commercial development bonus shall be consistent with the coastal resource protection policies, and where applicable, the public access requirements of the certified Carlsbad Local Coastal Program. ... The affordable housing agreement shall guarantee the affordability of the affordable units for a minimum of 55 years or a longer period of time if required by the construction or mortgage financing assistance program, mortgage insurance program, or rental subsidy program.

Violations & Fines
The decision-making body (Planning Commission or Housing Policy Team, with appeal to City Council) can deny an incentive or waiver only on written findings backed by substantial evidence, such as no identifiable cost reduction, conflict with state or federal law, or a specific adverse impact on public health, safety, or a historic resource that cannot be feasibly mitigated. An affordable housing agreement that is not recorded before final map or building permit issuance blocks the project from proceeding, and a recorded agreement binds all future owners and successors for the full affordability term.
