In Santa Ana, 44.6% of occupied homes are lived in by their owner and 44.2% of all homes are detached single-family houses. Condos, townhomes and apartments usually need approval from the building or association first.
Half of Santa Ana's homes were built before 1969. Panels last decades, so if your roof is near the end of its life, ask installers whether to replace it before they install.
