Opinion No. 17-602
April 9, 2019

THE HONORABLE SHARON QUIRK-SILVA, MEMBER OF THE STATE ASSEMBLY, has requested an opinion on the following question:
The Density Bonus Law (Gov. Code, ?? 65915-65918) rewards real estate developers who provide affordable housing by permitting them to build additional units, called ?density-bonus units.? May a city or county condition its grant of a developer’s application for a density bonus upon the developer’s payment of a ?public benefit fee? that is imposed only on the density-bonus units?
No. A city or county may not condition its grant of a developer’s application for a density bonus under the state Density Bonus Law upon the developer’s payment of a public benefit fee imposed only on the density-bonus units.
Under the Planning and Zoning Law,1??[t]he Legislature has required every county and city to adopt ?a comprehensive, long-term general plan for the physical development of the county or city ….??2?The general plan provides a roadmap for future development, as well as the city’s or county’s ?fundamental policy decisions about such development.?3?A general plan is required to include, among many other things, ?a statement of the standards of population density and building intensity recommended for the various districts ….?4
The Legislature has enacted several statutes aimed at redressing the shortage of affordable housing in the state, including?section 65915, the Density Bonus Law5?at issue here. The Density Bonus Law incentivizes the building of affordable housing by granting developers ?a density increase over the otherwise maximum allowable gross residential density,?6?as well as other incentives or concessions,7?in return for a commitment to provide affordable housing as part of a development project.8??In other words, the Density Bonus Law ?reward[s] a developer who agrees to build a certain percentage of low-income housing with the opportunity to build more residences than would otherwise be permitted by the applicable local regulations.??9?In general, the larger the percentage of affordable housing included in the project and the needier the population served, the larger the density bonus.10?Furthermore, if the developer meets the requirements of?section 65915, the city or county?must?award a density bonus.11
We are informed that several cities12?have adopted ordinances that condition the grant of a density bonus under?section 65915?on the payment of a public benefit fee imposed only on the additional units provided by the density bonus. Public benefit fees can include monetary contributions toward community improvements, such as bicycle paths, public parking, and open spaces, as well as the actual provision of such improvements. Does such an ordinance run afoul of the Density Bonus Law?
This is a question of preemption. Although ?[a] county or city may make and enforce within its limits all local, police, sanitary, and other ordinances and regulations not in conflict with general laws,?13?a local ordinance that conflicts with the state Planning and Zoning Law is invalid.14?A conflict exists, and the ordinance is preempted, if the local legislation is contradictory to general law.15
Legislative intent is clear with respect to density bonuses and other incentives for building affordable housing: ?In enacting this chapter it is the intent of the Legislature that the density bonus or other incentives offered by the city, county, or city and county pursuant to this chapter shall contribute significantly to the economic feasibility of lower income housing in proposed housing developments.?In the absence of an agreement by a developer in accordance with?Section 65915, a locality shall not offer a density bonus or any other incentive that would undermine the intent of this chapter.?16?Section 65915?itself also states, ?This chapter shall be interpreted liberally in favor of producing the maximum number of total housing units.?17?As we have observed, ?It is apparent that the intent of the legislative scheme as a whole is to encourage the construction of housing for persons and families of low or moderate income. The Legislature has essentially directed cities and counties to provide incentives to housing developers in return for the construction of housing units for such persons and families.?18
The type of ordinance at issue here?one that imposes a fee only on additional units allowed as a density bonus?contradicts the Density Bonus Law. Rather than encourage construction of affordable housing, such a fee taxes developers for acquiring density bonuses. Thus the local law disincentives what the state law means to incentivize. Therefore, we conclude that an ordinance imposing a fee only on units created through a density bonus under?section 65915?is invalid.
Courts have reached similar conclusions where a local law or practice has diminished the benefits of the Density Bonus Law. For instance, a county required a certain amount of affordable housing in new developments, but did not count those units in calculating a density bonus under?section 65915. The court found the county ordinance invalid as conflicting with the Density Bonus Law.19??To the extent the ordinance requires a developer to dedicate a larger percentage of its units to affordable housing than required by?section 65915, the ordinance is void.?20?Likewise, a court rejected a city’s growth-control ordinance that expressly excluded low-income and senior housing built with a density bonus from the enumerated exemptions to the city’s established growth limit. The court held that the city’s ordinance was invalid because it conflicted with the Density Bonus Law by discouraging developers from proposing housing that would otherwise qualify for bonuses.21
In sum, an ordinance conditioning the grant of a bonus under the state Density Bonus Law upon payment of a public benefit fee imposed only on the density bonus units is inimical to the Density Bonus Law itself and, therefore, invalid.22

Because we conclude that a city or county may not condition its grant of a density bonus under?section 65915?upon the developer paying a public benefit fee imposed only on the density bonus units, we need not answer the additional question posed to us, which presents the same issue under more specific circumstances: Where a city ordinance allows a developer to increase the otherwise maximum allowable base residential density of its development project to a ?Tier 1 density? if it agrees to pay a public benefit fee on the units above the standard base density, and the developer agrees to pay that fee to obtain such an increase, may the city condition its grant of the developer’s application for a density bonus, above the Tier 1 density, under the state Density Bonus Law upon the developer’s payment of an additional public benefit fee assessed only on the units granted under the Density Bonus Law? We have not been asked, and express no opinion about, the validity of the portion of the ordinance described in this question that allows a developer to increase the generally allowable maximum residential density by paying a fee imposed on the additional units.
