Many building developers utilize a single purpose entity limited liability company (an “LLC”) to purchase and develop property, such as an apartment complex, a subdivision, or a shopping center. Generally, an LLC’s debts, whether incurred or judicially imposed, belong only to the LLC, not to its members.  However, an LLC’s individual member may be subject to personal liability under the doctrine of alter ego liability if (1) the individual and the LLC share a unity of interest and ownership such that the separate personalities of the two no longer exist, and (2) treating the debts as the LLC’s alone would impose an inequitable result that rewards the bad faith of the individual.  A recent legal decision from Southern California highlights the dangers of disregarding an LLC’s corporate formalities during any construction project.
