Developer Fee Inflation Adjustment Explained

Developer fee requirements vary by project and jurisdiction. This article is provided for general informational purposes and does not constitute legal advice. Applicants and school districts should verify current rates, effective dates, and requirements with the appropriate governing authority or legal counsel.

A developer fee inflation adjustment is an update to a developer fee rate that reflects changes in inflation, construction costs, or another applicable cost index. These adjustments help ensure fees collected from new development continue to reflect the cost of constructing or expanding public facilities. For school districts, developer fees, often called school impact fees, help fund facilities associated with new residential and commercial development. In California, school districts are authorized to collect developer fees under state law and the maximum Level 1 developer fee is adjusted every two years using the statewide Class B construction cost index.

What Is a Developer Fee Inflation Adjustment?

A developer fee inflation adjustment is a periodic change to a developer fee rate based on inflation, construction costs, or another legally authorized cost measure. Its purpose is to help keep fee amounts aligned with changing construction costs over time.

The terms inflation adjustment and developer fee increase are sometimes used interchangeably, but they do not always mean the same thing.

Why Are Developer Fees Adjusted for Inflation?

Developer fees help offset the cost of school facilities needed to serve new development. As construction costs increase, fees that remain unchanged may cover a smaller share of those expenses. Rising costs for labor, materials, equipment, and construction services can all affect school facility budgets.

Inflation adjustments help keep fee limits or adopted rates aligned with those changing costs. An increase to a state's maximum allowable fee does not necessarily mean every school district will immediately charge the new maximum. Districts must still follow applicable legal and local adoption requirements.

How Does a Developer Fee Inflation Adjustment Work?

Although the process varies by jurisdiction, most developer fee adjustments follow a similar pattern. A governing agency reviews applicable cost data, calculates an adjustment, publishes updated fee information, and applies new rates according to state and local requirements.

What Factors Influence Developer Fee Inflation Adjustments?

Developer fee adjustments may reflect multiple economic and regulatory factors. The weight given to each factor depends on applicable laws, fee studies, and local methodology.

Construction Cost Changes

Construction cost indices track how the cost of building projects changes over time. These indices may account for labor, materials, equipment, contractor expenses, and other construction inputs.

Inflation and Economic Conditions

Broader inflation can increase the cost of goods and services needed to plan, construct, furnish, and maintain school facilities. However, general consumer inflation is not always the same as construction inflation. Construction prices may rise faster or slower than the overall economy depending on demand, supply constraints, interest rates, regional development activity, and other market conditions.

Changes in Construction Labor Costs

Labor is a significant part of most construction budgets. Rising labor costs, construction workforce shortages, and contractor pricing can increase school construction expenses and influence future fee adjustments.

Changes in Material Costs

Price changes for materials such as steel, concrete, lumber, and electrical equipment can significantly affect construction costs.

Local and State Regulations

Local policies may determine how a district adopts rates, documents the relationship between development and school facility needs, records payments, and communicates requirements to applicants. California laws can also affect when certain fees may be collected. For example, Senate Bill 937, effective January 1, 2025, changed the timing of fee collection for certain residential developments. Among other changes, it generally restricts school districts from requiring payment from qualifying “designated residential development projects” until the first certificate of occupancy or temporary certificate of occupancy, subject to statutory exceptions.

When Do Developer Fee Adjustments Take Effect?

The effective date depends on applicable state law and local policy. A state agency may establish an effective date for a new maximum fee, while a school district may establish a separate implementation date after completing its local adoption process. Applicants should always verify the effective date with the applicable school district.

In California, the maximum Level 1 adjustment is determined at the State Allocation Board’s January meeting every two years and is effective at the state level as of that meeting date. In January 2026, the Board increased the maximum Level 1 rates to $5.38 per square foot for residential development and $0.87 per square foot for commercial or industrial development.

How Does Developer Fee Inflation Affect Development Projects?

A school developer fee increase can affect both project applicants and the districts responsible for administering fees.

Impact on Developers and Project Applicants

Developers and project applicants may face higher costs when a new rate takes effect. The impact depends on the size and type of development, the district’s adopted rate, and the rules used to calculate the assessable area. Applicants may also need to update estimates, financing documents, permit schedules, contracts, or internal approvals.

Impact on School Districts

For school districts, updated rates may provide additional revenue to help address increasing facility costs. However, implementing a rate change also creates administrative responsibilities. Districts must update fee schedules, forms, websites, and administrative procedures to ensure accurate fee collection and compliance.

Impact on Project Budgets and Timelines

Fee changes may affect project budgets and schedules, particularly if rates change before payment is due.

How Developer Fee Inflation Can Affect a Project

Applicants can reduce avoidable delays by using a school development project registration checklist, preparing a development project information template, and reviewing common project registration mistakes before submitting a project.

How Can Developers Prepare for Developer Fee Adjustments?

Check Current Developer Fee Rates

Obtain the current fee schedule directly from the school district or applicable governing authority. Do not rely solely on an old estimate or prior project. For additional information, review the latest California school developer fee rates.

Confirm the Effective Date

Ask when the rate became effective and which date determines the applicable fee. Depending on local requirements, the relevant date may involve project registration, permit issuance, fee assessment, payment, final inspection, or certificate of occupancy.

Register Projects Early

Begin the registration process early enough to identify missing information and confirm the district’s current rates and payment requirements. Registration alone may not establish or lock in a fee rate, and applicants should confirm the district’s specific fee policy.

Budget for Potential Fee Changes

Include an appropriate contingency in long-term project budgets, especially when construction, permitting, or payment may occur after an upcoming adjustment date.

Keep Project Information Up to Date

Changes in square footage, development type, address, parcel information, or scope may affect the fee calculation. Submit updated information promptly and maintain consistent details across applications, plans, permits, and supporting documents.

Track Payment and Compliance Requirements

Maintain copies of calculations, invoices, receipts, and Certificates of Compliance. Accurate records can help resolve questions and demonstrate that applicable requirements were completed.

How Can School Districts Manage Developer Fee Adjustments?

School districts can manage changing fee rates more effectively by establishing a repeatable process for reviewing, approving, publishing, and applying adjustments.

A district’s process may include:

• Monitoring state regulations, legal updates, and applicable cost indices.
• Reviewing the district's fee study and adopted developer fee rates.
• Completing required legal, board, and public notice procedures.
• Establishing an implementation date and updating forms, calculators, websites, and staff resources.
• Verifying fee calculations before updated rates take effect.
• Communicating changes to stakeholders and maintaining accurate payment and compliance records.

Centralized records are especially important when a district manages a high volume of projects or multiple fee categories. Without a consistent system, staff may have difficulty determining which rate was active, when an applicant submitted information, and whether the correct amount was collected.
