Title 24 Projects in Santa Ana
Santa Ana is one of Orange County's oldest and most densely built cities. Historic neighborhoods such as Floral Park and French Park sit near downtown, and much of the rest of the city is made up of compact postwar homes on small lots, along with duplexes, fourplexes and older apartment buildings.
Small lots and high demand for housing push projects toward making better use of existing space. Garage conversions and junior ADUs are especially common, because they add a unit without a new building footprint. Detached ADUs, rear additions and the conversion or rebuilding of older small multifamily buildings follow close behind.
For the energy report, the main issue is usually the age of what is already there. A garage conversion has to bring an uninsulated shell and slab up to the standard of conditioned living space. Additions to pre-war and postwar homes may be modeled together with walls, windows and equipment that predate modern codes. And duplex to fourplex projects use a different compliance path from single-family homes. Our garage conversion Title 24 page, multifamily Title 24 reports and Title 24 requirements explain each case.
