Title 24 report pricing varies more than most homeowners expect, and the range isn't arbitrary — it reflects real differences in the complexity of the energy modeling involved.
A Title 24 report in California starts at $195 for straightforward residential projects. ADU reports start at $250, JADU reports at $225, new-construction reports at $245 and commercial reports at $350. Final pricing depends on the project type, scope and complexity.

What Affects the Cost of a Title 24 Report?
For straightforward residential alterations — a room addition, a remodel touching HVAC or windows — expect to pay in the $195–$295 range. These projects typically use the prescriptive compliance path, which involves less modeling complexity than a full performance approach.
ADU and JADU projects tend to run somewhat higher, generally $225–$300, because accessory dwelling units often involve their own complete HVAC and envelope systems that need to be modeled independently from the main house, even when they share a structure.
New construction is the most involved category, typically starting around $245 and scaling up with square footage and complexity. A full CBECC-Res model for a new single-family home accounts for every energy-consuming system in the building, plus solar PV sizing and battery storage provisions. Projects with permit applications submitted on or after January 1, 2026 must comply with California's 2025 Energy Code; projects submitted before that date may remain subject to the 2022 cycle.
Commercial projects follow a different fee structure entirely — Nonresidential Energy Compliance (NREC) reports typically start at $350 for small spaces and scale with conditioned square footage, system count, and occupancy type.
A few factors that can move the price in either direction: rush turnaround adds a flat $95 for same-day service on orders placed before 10am, revisions after plans change start at $75 rather than the full original report price, and unusually complex projects — additions to non-conforming structures, mixed-use buildings, multiple HVAC zones — may carry a complexity premium.
What should make you cautious: extremely low quotes (under $150 for anything beyond the simplest project) sometimes indicate a consultant using outdated software versions, skipping HERS flag review, or not actually running full compliance calculations. A Title 24 report that gets rejected at plan check costs you more in time than you saved in fees. Ask any consultant which software they use (CBECC-Res/CBECC-Com are the current state-approved tools) and whether HERS verification requirements are clearly flagged in the deliverable.

Frequently Asked Questions
Title 24 reports currently start at $195 for straightforward residential projects. ADU reports start at $250, JADU reports at $225, new-construction reports at $245 and commercial reports at $350. The exact price depends on the project scope and complexity.
Pricing varies because different projects require different levels of energy modeling. Building size, project type, HVAC systems, envelope details, plan completeness and the required compliance path can all affect the work involved.
Not always. Some architects and designers include energy compliance coordination, while others require the owner or contractor to hire a separate Title 24 consultant. Confirm what is included before submitting for a permit.
