One can surmise that the few positive reviews of Regents La Jolla on this website were written by those with a vested interest (e.g. leasing staff, Integral Communities sales staff).
The predominently negative reviews here are accurate. The complex has gone downhill in the past few years, and now that the bulk of the complex has been converted to condos-for-sale, it has deteriorated to nothing more than a glorified, overpriced slum.
Security is virtually non-existent. Recently there has been a rash of break-ins and vandalism. A few years ago the on-site security patrol was a visible force; the "courtesy patrol" now is a (619) telephone no. to a pager.
The condo developer, Integral Communities, has not upgraded the sound insulation in the walls and ceilings of the units. This complex was built on-the-cheap, like a cheap motel. Residents can hear their neighbors' lives through the walls, floors, and ceilings. Many units look into those directly opposite - no privacy unless you keep your blinds closed 24/7! The only upgrades that Integral Communities has made are cosmetic.
It is widely known that sales of the condos is very weak. Recent newspaper ads promoted "winter move-ins". It is now spring, and no residents have moved into condo section. Some buildings are completely empty; not one unit occupied.
If you are thinking of buying, hold on to your money and wait for the prices to COME DOWN! There is an oversupply of condos in UTC, with several complexes having commenced previews and/or sales since February 2005.
