Summary

The City of Rocklin implements state density bonus law through its own Density Increase Incentive Program, Rocklin Municipal Code Chapter 17.96. Projects of five or more dwelling units in any residentially zoned district can apply for a density bonus, and the city must guarantee the affordable units for at least thirty years.

17.96.030 - Qualifications. All proposed housing developments (including residential tentative subdivision maps) that would create five or more dwelling units shall be eligible to apply for a density bonus (including incentives, and/or concessions) consistent with the requirements, provisions, and obligations set forth in California Government Code Section 65915, as may be amended. ... 17.96.060 - Retention. Consistent with the provisions of California Government Code Section 65915 et seq. whenever a density increase or other incentive is approved for a project, the city and the applicant shall agree to an appropriate method of assuring the continued availability of the density bonus units for a period of thirty years or a longer period of time if required by the construction or mortgage financing assistance program, mortgage insurance program, or rental subsidy program.

Full Breakdown

Chapter 17.96, adopted by Ordinance No. 977 in October 2011, applies to all zoning districts that allow residential uses under Section 17.96.020. Section 17.96.030 makes any proposed housing development, including a residential tentative subdivision map, that would create five or more dwelling units eligible to apply for a density bonus, incentives, and concessions consistent with California Government Code Section 65915. Section 17.96.040 ties the actual bonus amount and available incentives directly to the schedule in Government Code Section 65915(f) and (d) rather than setting a separate city figure.

Applications go to the Planning Division of the Community Development Department under Section 17.96.050 and must include a project description, unit counts and sizes, the number of units reserved for extremely low, very low, or low income households or seniors, the zoning and general plan designation, a site plan, and a list of requested concessions with justification; the application is processed alongside the project's other entitlements and decided by the planning commission or city council at the same hearing, or by the community development director if no other hearing applies.

Section 17.96.060 requires the city and applicant to agree on a method assuring continued availability of the density bonus units for thirty years, or longer if a financing, mortgage insurance, or rental subsidy program requires it. The chapter also intersects with Chapter 17.95's inclusionary housing requirement, adopted separately by Ordinance No. 1195 in November 2025, which triggers on projects of ten or more units.

Violations & Fines

Chapter 17.96 does not print its own standalone penalty schedule; density bonus units are secured instead through the affordability agreement required by Section 17.96.060, and failure to comply with that recorded agreement or with the qualifying conditions of Section 65915 exposes an applicant to loss of the density bonus, incentives, or concessions the city approved for the project.
