What Are Capacity Fees?
Capacity fees are one-time charges imposed by public utility districts to help cover the cost of expanding infrastructure—such as water and sewer systems—when additional system demand is created. These fees are commonly assessed during new development or when significant modifications to a property increase the demand for public utilities.
When Are Capacity Fees Typically Applied?
- Direct Connection to the Utility Main:
Capacity fees are usually charged when a new building or unit connects directly to a utility’s main sewer or water line. The new connection may create additional demand on the system, requiring infrastructure upgrades funded by these fees. - Public Infrastructure Expansion:
If a project results in the need for expanded infrastructure—such as larger sewer lines, lift stations, or added water treatment capacity—capacity fees help recover those costs and ensure the system remains functional for all users.
How This Applies to ADUs
When it comes to Accessory Dwelling Units (ADUs), the situation is different. Many ADUs are connected indirectly through the primary home’s existing utility lateral rather than connecting directly to the main line. In these cases, no new infrastructure is added, and the system’s existing capacity is reused—not expanded.
Under California Government Code § 65852.2(f), a public agency may not charge a capacity fee for an ADU unless it requires a direct connection to the utility. This protection was designed to support housing affordability by removing unnecessary financial barriers to building ADUs.
The Concern
In some cases, including within the Ojai Valley Sanitary District (OVSD), homeowners have reported being charged capacity fees for ADUs despite not being required to install a direct connection to the sewer main. These fees have been publicly challenged as inconsistent with state ADU law and may place unfair financial burdens on homeowners who are contributing to California’s housing goals.
If you were charged a capacity fee for an ADU that connects through your main home’s existing sewer line, you may wish to learn more about your rights under California law or consult an attorney.
Legal Principles Supporting the Concept of Prepaid Inherent Capacity
Several California statutes and legal doctrines support the argument that capacity fees should not be imposed when existing infrastructure—especially infrastructure paid for through earlier fees—can accommodate additional usage without exceeding its design limits. This concept is particularly relevant to ADUs that connect to existing laterals without requiring new system capacity.
Below are the most relevant legal authorities:
1. Government Code § 66013 – Nexus Requirement for Capacity Fees
This statute requires a direct relationship (nexus) between a capacity fee and the cost of providing additional capacity. If existing laterals or system components were funded by prior fees and are not being expanded, the imposition of a new fee lacks legal justification.
Key Clause:
“A fee for capacity shall not exceed the estimated reasonable cost of providing the service for which the fee is charged.” (Gov. Code § 66013(b))
Application:
If the capacity of an existing lateral has already been paid for and is not exceeded by the addition of new drainage fixture units (DFUs), no new service is being provided. Imposing a new capacity fee under these conditions would violate § 66013.
2. Proposition 218 – Proportionality Requirement
Prop 218 mandates that all property-related fees be proportional to the cost of the service provided. Charging a flat or full-capacity fee where no new infrastructure or service is being added violates this principle.
Key Clause:
“Revenues derived from the fee or charge shall not exceed the funds required to provide the property-related service.” (Cal. Const., Art. XIII D, § 6(b)(1))
Application:
If the infrastructure already accommodates the additional DFUs without modification or expansion, then the fee exceeds the actual cost of providing service and is disproportionate—thus invalid under Proposition 218.
3. Public Utilities Code § 1501 et seq. – Fair and Reasonable Rates
This code requires that utility fees be fair, reasonable, and based on the cost of service provided. Charging for infrastructure that was previously funded—and still has unused capacity—may violate this principle.
Key Principle:
“Charges must be based on the cost of the service provided.”
Application:
If no new costs are incurred by the utility due to the added DFUs, a new capacity fee may be deemed unreasonable and subject to challenge.
4. Takings Clause – Nollan / Dolan Doctrine
Under U.S. Supreme Court precedent, government exactions (including capacity fees) must be proportionate to the impact of the development.
Key Precedent:
“An exaction must be related in nature and extent to the impact of the proposed development.”
— Dolan v. City of Tigard, 512 U.S. 374 (1994)
Application:
If a property owner’s added DFUs fall within the lateral’s existing design capacity, there is no increased impact, and thus no valid basis for a new capacity fee. The fee would fail both the nexus and proportionality tests established in Nollan and Dolan.
5. Government Code § 66016 – Fee Transparency and Documentation
Agencies must justify new or increased fees with clear documentation showing the cost basis for the fee.
Key Clause:
“Any action adopting or increasing a fee shall include the evidence necessary to demonstrate that the fee does not exceed the estimated reasonable cost.”
Application:
If no new infrastructure is required and no additional capacity is being provided, the agency cannot meet the evidentiary burden required by § 66016. The fee is therefore unjustified and subject to legal challenge.
6. Government Code § 65008 – Equal Treatment and Non-Discrimination
This statute protects against discriminatory land use practices, including the unequal application of fees.
Application:
If other property owners with similarly situated ADUs are not charged capacity fees, but you are, this may constitute disparate treatment in violation of § 65008.
7. Prepaid Capacity Through Historical Fees
In many cases, capacity fees were paid during the original development of the property, including for the installation of sewer laterals designed with future use in mind. These fees prepaid for system capacity that remains available today.
Legal Argument:
Charging a new capacity fee for infrastructure that was already paid for during initial development—and whose capacity has not been exceeded—constitutes double billing. This contradicts the purpose of capacity fees, which are intended to recover costs for new demand, not to charge twice for existing capacity.
The Ojai Valley Sanitary District (OVSD) has been charging capacity fees to homeowners who build Accessory Dwelling Units (ADUs), even when those ADUs connect indirectly to the sewer system through the existing lateral line of the primary residence. This practice has raised significant legal concerns under several provisions of California law, particularly Government Code § 65852.2(f).
⚖️ What the Law Says
California law prohibits local agencies, including special districts like OVSD, from imposing capacity fees on ADUs unless a new or separate utility connection is mandated. According to Gov. Code § 65852.2(f):
“A local agency, special district, or water corporation shall not impose a connection fee or capacity charge for an accessory dwelling unit… unless the accessory dwelling unit is constructed with a new or separate utility connection directly between the accessory dwelling unit and the utility.”
In other words, unless OVSD requires a direct connection between the ADU and the sewer main, they are not authorized to charge a capacity fee.
🧾 How Indirect Connections Differ
An indirect connection means the ADU shares the existing lateral line from the main home and does not create a new connection to the utility’s main infrastructure. These connections typically do not increase demand on the system beyond what the original lateral was designed to handle. No new infrastructure is added, and no expansion of system capacity occurs.
If the ADU is using the existing connection, and the lateral line was already sized (and paid for) when the main home was built, there is no legal or technical justification for charging an additional capacity fee.
❓ Why This Practice Is Being Challenged
- Lack of Nexus: Under Gov. Code § 66013, capacity fees must be based on the actual cost of providing additional service. If no new capacity is being added, the fee may violate this law.
- Proportionality Issues: Under Proposition 218, fees must be proportional to the service provided. Charging a flat capacity fee for an ADU that adds no measurable system burden may be unconstitutional.
- Unequal Treatment: Under Gov. Code § 65008, inconsistent or selective enforcement of fees may raise equal protection concerns.
🚫 Is It Legal?
The legality of OVSD’s capacity fee policy for ADUs with indirect connections is currently being challenged. While OVSD asserts it has the authority to assess such fees, many homeowners and advocates argue that doing so violates both the letter and spirit of California’s ADU laws.
Until a court makes a definitive ruling, these practices remain legally disputed, and affected homeowners may wish to consult legal counsel or file a complaint with the California Department of Housing and Community Development (HCD).
The capacity fees imposed by the Ojai Valley Sanitary District (OVSD) are having a significant and far-reaching effect on homeowners pursuing Accessory Dwelling Unit (ADU) projects. These fees—reportedly as high as $16,000 per unit—have created unexpected financial burdens and introduced delays that are slowing or halting the development of urgently needed housing.
1. Financial Strain on Homeowners
Many homeowners build ADUs as a cost-effective way to generate rental income, house family members, or support local housing needs. However, the imposition of high sewer capacity fees—especially after construction is complete or without prior notice—has disrupted these plans.
- Inflated Project Costs: Homeowners are forced to absorb thousands of dollars in fees not originally included in their project budgets.
- Canceled or Delayed Projects: Some homeowners are forced to postpone or abandon their ADU plans due to an unexpected and unaffordable cost increase.
- Financing Challenges: Sudden fees can interfere with existing loans, increase debt loads, or complicate approval from lenders, especially when charged retroactively.
2. Delays and Legal Uncertainty
Beyond financial concerns, capacity fees are also causing substantial delays in project completion and creating legal complications:
- Post-Completion Charges: In at least one case, a homeowner reported being billed for capacity fees only after construction is completed and inspections passed. This can delay certificates of occupancy and the legal use of the ADU.
- Administrative Confusion: Fee notices that arrive late or lack clarity can lead to confusion among homeowners—many of whom assumed their project was fully approved.
- Legal Disputes: Homeowners who challenge the fees often face extended administrative or legal processes, further stalling occupancy and use of their ADUs.
3. Barriers to Housing Development
California’s ADU laws were designed to encourage small-scale housing development as part of the solution to the state’s housing crisis. However, fee policies like those enforced by OVSD may discourage participation in this effort by making ADUs cost-prohibitive for many.
- Reduced Participation: The financial and procedural barriers posed by unexpected fees discourage homeowners from initiating or completing ADU projects.
- Policy Undermined: These outcomes run counter to the goals of state legislation aimed at expanding affordable housing options through streamlined and lower-cost development processes.
In Summary
The sewer capacity fees assessed by OVSD—particularly where no new direct connection is required—are having a profound impact on homeowners in the Ojai Valley. These fees are raising costs, delaying projects, disrupting financing, and in some cases, forcing homeowners to walk away from much-needed housing solutions. Left unaddressed, these practices risk undermining the effectiveness of California’s ADU initiatives and the broader goal of improving housing affordability and access.
HCD Oversight and the Lack of Enforcement Against OVSD
The California Department of Housing and Community Development (HCD) plays a key role in promoting the development of Accessory Dwelling Units (ADUs) by ensuring that local governments and special districts comply with state laws designed to expand affordable housing. However, in the case of the Ojai Valley Sanitary District (OVSD) and its application of sewer capacity fees to ADUs, HCD’s lack of enforcement has left homeowners without meaningful support or recourse.
1. HCD’s Role in Enforcing ADU Law
Under California Government Code § 65852.2, HCD is responsible for reviewing and enforcing compliance with state laws that encourage ADU construction. These laws were created to remove unnecessary barriers—such as excessive fees—that discourage homeowners from building ADUs.
A key provision, Section 65852.2(f), limits the imposition of utility connection fees and capacity charges. Specifically, it allows a local agency or special district to impose a capacity fee only if an ADU is required to make a new, direct connection to the main utility line. In cases where the ADU connects indirectly through the primary residence, such fees are not permitted under state law.
Despite this, OVSD has continued to charge capacity fees for ADUs that do not make direct connections—raising serious questions about compliance.
2. HCD’s Limited Response
Homeowners impacted by these fees have reached out to HCD seeking intervention. However, many report the following:
- Lack of Active Enforcement: While HCD has acknowledged awareness of OVSD’s practices, it has not taken formal action to require compliance or prevent continued fee collection.
- No Clear Remedy for Homeowners: Without HCD intervention, homeowners are left navigating complex administrative and legal channels on their own, often without clarity or support from the state agency tasked with oversight.
This lack of enforcement has allowed the contested fee practices to persist, despite legislative intent.
3. Undermining the Purpose of California’s ADU Laws
California’s ADU laws were designed to address the housing crisis by encouraging homeowners to develop secondary units without facing the same fees and regulatory hurdles as new full-size homes. OVSD’s capacity fee policy runs contrary to that goal—and HCD’s inaction allows that conflict to continue.
- Increased Costs for Homeowners: Imposing fees where none should apply makes ADU projects less affordable and less viable for many homeowners.
- Barriers to Housing Production: Instead of helping streamline ADU development, HCD’s inaction may be contributing to project delays, abandonment, or legal disputes—all of which deter housing growth.
Conclusion
HCD has a legal and policy-driven obligation to ensure that local agencies—including special districts like OVSD—comply with state ADU law. Without meaningful oversight or enforcement, homeowners remain exposed to potentially unlawful fees that threaten both their financial well-being and the broader goal of increasing California’s housing supply. Advocates and affected homeowners must continue to press HCD to uphold its responsibilities and take action to protect ADU development across the state.
The fight against OVSD’s unlawful capacity fees affects more than just the directly impacted homeowners—it affects every Californian who believes in fair housing laws, government accountability, and the right to build without unjust fees.
