Why is four-season rooms different in North County Inland San Diego?
Inland communities in Escondido, Vista, and San Marcos see summer temperatures 10-15 degrees warmer than the coast, making full insulation and a mechanical cooling connection worth the additional cost over a three-season enclosure. Many 1980s and 1990s tract homes in this region have rear-facing patios that are well-positioned footprints for a four-season addition, and the resale value bump from permitted conditioned square footage is meaningful here.
