Does the Price of a Title 24 Report Depend on My City or Climate Zone?
Not for us. Price follows building size, project type and delivery speed, and a zone 16 house costs the same to document as one in zone 6. Location still changes the design: each of the 16 climate zones has its own prescriptive values, and a city can add a reach code.

What the state fixes everywhere
The Commission set typical weather data, prescriptive packages and energy budgets for 16 climate zones. The zone comes from the climate zone or ZIP code of the proposed building, and the same adjustment is applied to the proposed and standard designs. The certificate of compliance format is Commission-approved and identical statewide, so reports look alike in every city. A quote from another city is therefore a fair comparison, as comparing two quotes shows.
What the climate zone changes
It changes the numbers the design must meet, which is design effort rather than a fee. In Table 150.1-A the maximum window U-factor is 0.30 in zones 6 to 10 and in zone 15, and 0.27 elsewhere. The maximum SHGC is 0.23 in most zones, 0.20 in zone 15 and not required in zones 1, 3, 5 and 16. Steep-slope roofs in zones 10 to 15 need an aged solar reflectance of at least 0.20 or an SRI of 16. The same plan can pass in one zone and need glass changes in another. Look yours up on the climate zones page.
When a city makes the job bigger
A local government may enforce stricter energy standards only after adopting a cost-effectiveness determination at a public meeting and receiving a Commission finding that they require buildings to use less energy than Part 6. Where such a reach code exists, the report must meet it as well, which can add modelling or measures. What a reach code is explains how to find out whether yours has one.
Who approves it
The enforcement agency is the city, county or state agency that issues the building permit, and it approves the certificate by stamp or authorized signature before the permit issues. Departments differ in who reviews and how; see who enforces Title 24 and the locations we serve.
A tract split between zones may use the zone holding half or more of its dwelling units. Our prices are on the cost page, and orders start on the residential report page.

Frequently Asked Questions
Not with us. Climate zone and compliance path do not change the price; building size, unit count and delivery speed do.
Only if the new site is in a different climate zone or under a local reach code. The zone sets the prescriptive values and the budget, so the house must be re-run for a new zone.
