The KB crew in OC is a good crew, however, this site is a dog. Right next to the train tracks in a "redevelopment zone" which aero has erroneously noted as a ghetto (barrio is the more appropriate description).
On top of that, KB will give you the bare bones in a home as they pride themselves on letting their homebuyers pick their upgrades. Somehow their optional upgrades include insulation and sound attenuation materials between floors and if you choose to skip, you have sound issues within your own home. This may not be the case as these are condos. KB has a HORRENDOUS reputation as being a super low quality builder, they even have to have special disclosures and special oversight due to some very dishonest sales techniques. For example, KB used to make very very small master bed rooms, but they would compensate by installing custom, shortened beds in their models.
Don't buy here, don't buy in any of those new developments in north county. Buy from Lennar who's EI plans actually seem pretty decent to me, although i hear they are phasing those out in their lower end product.
KB's project in Warner Center is on fire.
