Title 24 Reports in Oxnard
Oxnard is climate zone 6, the mild coastal zone. Santa Paula and Ojai, inland behind the coastal ridge, are zone 9 — and the drive between them is short.

Coastal plain, not inland valley
Oxnard, Port Hueneme and Ventura all carry zone 6, the mild coastal designation shared with the Los Angeles beach cities well to the south. Camarillo, still on the plain, carries zone 6 too. Behind the coastal range it changes: Santa Paula and Ojai carry zone 9, a warmer inland zone.
Ojai is the case that breaks the intuition. It is close to the ocean in a straight line but sits in its own valley behind the ridge, and it is assessed as inland rather than coastal.
What the ocean does to a project here
Zone 6 is moderated year-round, so neither heating nor cooling loads are severe and the compliance margin tends to be driven by the envelope and glazing rather than by equipment capacity. That is a genuinely easier starting point than an inland zone — but it also means a design cannot borrow figures from a project in the Santa Clara River valley twenty minutes away.
The kind of work this produces
Oxnard has a large agricultural and industrial base alongside its housing, so alongside residential additions and ADUs there is a steady volume of nonresidential and cold-storage-adjacent work where mechanical scope rather than floor area drives the documentation. Permits are issued by the city; projects on unincorporated land go to Ventura County.

- Which climate zone applies to an Oxnard project?

- Does an Oxnard addition or ADU need an energy report?
- Will an Oxnard report work for a Santa Paula project?
- Does the city or Ventura County issue my permit?
Oxnard projects fall in California climate zone 6. The zone drives the envelope and equipment requirements a report has to meet, and a single city can span more than one, so it is confirmed per address.
