CA Opinion No. 17-602 2019-04-09

Can a California city or county charge a developer a public benefit fee that applies only to the bonus units it earned for providing affordable housing?

Short answer: No. The state Density Bonus Law preempts a local ordinance that conditions a density bonus on payment of a public benefit fee imposed only on the bonus units. Such a fee taxes the very incentive the state law was designed to provide.

Plain-English summary

California's Density Bonus Law rewards housing developers who include affordable units in a project by letting them build additional ("bonus") units beyond what the local zoning code would otherwise allow. The Attorney General was asked whether a city or county can charge a "public benefit fee" that applies only to those bonus units, as a condition of granting the bonus. Several cities had adopted ordinances doing exactly that. Public benefit fees, as the AG described them, can include monetary contributions toward bicycle paths, public parking, open spaces, or the construction of those improvements directly.

The AG concluded the answer is no. The state Density Bonus Law preempts that kind of local fee. Government Code section 65917 declares that the density bonus and other incentives offered under the chapter "shall contribute significantly to the economic feasibility of lower income housing," and forbids localities from offering anything that "would undermine the intent of this chapter." Section 65915, subdivision (r) tells courts to read the chapter "liberally in favor of producing the maximum number of total housing units." A fee that targets only the bonus units does the opposite: it makes the bonus less valuable, reducing the financial incentive to include affordable units in the first place. That conflict between the state's pro-housing aim and the local fee was enough to invalidate the ordinance.

The AG cited two earlier preemption rulings on similar facts: Latinos Unidos Del Valle De Napa y Solano v. County of Napa (2013) 217 Cal.App.4th 1160, which struck down a county practice of not counting required affordable units when calculating the section 65915 bonus, and Building Industry Assn. v. City of Oceanside (1994) 27 Cal.App.4th 744, which struck down a city growth-control ordinance that excluded density-bonus housing from the enumerated exemptions to the city's growth limit. The throughline is that local mechanisms that diminish the value of the state bonus collide with the state law and lose.

Common questions

Q: What is the Density Bonus Law in plain English?
A: A state law (Gov. Code, §§ 65915-65918) that gives developers extra building rights when they include affordable, senior, encourage youth, disabled veteran, homeless, or child care housing in a project. The bigger the affordable component, the bigger the density bonus. The Density Bonus Law applies to both general law and charter cities (§ 65918).

Q: What does "preemption" mean here?
A: California's constitution lets cities and counties pass local ordinances, but only if those ordinances do not conflict with state law (Cal. Const., art. XI, § 7). When a local rule contradicts a state rule, the state rule wins and the local rule is invalid. The Sherwin-Williams Co. v. City of Los Angeles (1993) 4 Cal.4th 893 test treats a local law as preempted when it is "contradictory to general law."

Q: Can a city ever require a fee in connection with a density bonus project?
A: This opinion narrowly addressed fees imposed only on the bonus units. The AG flagged but did not decide whether a different fee structure, such as a fee that applies uniformly to all units in a development, would survive. The AG also did not opine on the related but distinct "Tier 1 density" arrangement, in which a developer pays a fee to enable a higher base density before applying for the state bonus on top.

Q: Does this rule apply to charter cities?
A: Yes. Section 65918 says the Density Bonus Law applies to general law cities and charter cities alike.

Q: What if the local ordinance is presented as helping affordable housing in some other way?
A: The AG's reasoning focuses on the effect, not the label. A fee that directly reduces the value of the density bonus disincentivizes what the state means to incentivize. That is the contradiction that triggers preemption.

Q: Where can a developer raise this argument?
A: In the local entitlement process and, if necessary, in court. The Friends of Lagoon Valley v. City of Vacaville (2007) 154 Cal.App.4th 807 line of cases applies the Density Bonus Law's preemptive force to a wide range of municipal actions that diminish bonus value.

Background and statutory framework

The Planning and Zoning Law (Gov. Code, §§ 65000-66210) requires every California county and city to adopt a comprehensive long-term general plan including standards of population density and building intensity. Section 65915 sits inside that framework as a state-level incentive program for affordable housing: when a developer agrees to include the required percentage of affordable units, the local agency must grant a density bonus and one or more itemized concessions or incentives.

Section 65917 sets the policy floor: density bonuses and other incentives "shall contribute significantly to the economic feasibility of lower income housing," and a locality "shall not offer a density bonus or any other incentive that would undermine the intent of this chapter." Section 65915, subdivision (r) reinforces that with a liberal-construction directive: courts and agencies are to interpret the chapter "in favor of producing the maximum number of total housing units."

Within that policy frame, the AG concluded that an ordinance imposing a fee only on bonus units fights the state objective: instead of rewarding the developer for the affordable component, it taxes the reward. The AG did not need to weigh whether public benefit fees of that type might be valid in some other context (for example, applied uniformly to all units, or operating outside the state Density Bonus Law) to decide this case.

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?
CONCLUSION
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.

ANALYSIS
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
Gov. Code, §§ 65000-66210. Future undesignated statutory references are to the
Government Code.

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 disincentivizes 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 growthcontrol 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


Building Industry Assn. v. City of Oceanside (1994) 27 Cal.App.4th 744, 770; see also
Friends of Lagoon Valley v. City of Vacaville, supra, 154 Cal.App.4th at pp. 825-826
(section 65915 sets 35% as the highest density bonus a locality is required to give; to
prevent cities and counties from offering higher density bonuses would undermine policy
of providing incentives to developers to build low-income and senior housing); 63
Ops.Cal.Atty.Gen. 478, 480 (1980) (local government may comply with Density Bonus
Law by providing incentives or concessions alternative to those enumerated in the statute
so long as they are acceptable to the developer and “contribute significantly to the
economic feasibility of low and moderate income housing . . . ”).
21

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.
