Huntington Beach is a coastal Orange County city with active residential remodels and ADU projects.
Huntington Beach is in Climate Zone 6, California's southern coastal zone — your exact zone is determined by your project address and ZIP code, and we confirm it before modeling.

Title 24 Projects in Huntington Beach
Much of Huntington Beach was built out as single-family tract neighborhoods in the 1960s and 1970s, with newer developments, condos and beach-area homes filling in around them. Those older tract homes are now at the age where owners are expanding rather than moving, so second-story additions, whole-house remodels, tear-down rebuilds and backyard ADUs make up a large share of local Title 24 work.
The coastal climate changes the emphasis. Heating and cooling loads are both moderate, and many older homes near the beach were built without air conditioning. Adding a heat pump or central air during a remodel — or replacing a gas furnace — is a common reason a report is needed. For second-story additions, the model looks at the new walls, roof and windows, and it may include the existing house when the performance approach is used. Tear-down rebuilds are treated as new construction, which brings in solar PV where required. See home addition Title 24 reports and Title 24 calculations for more detail.
