What is the test for establishing a general plan of restrictions in a condominium?

It is, however, necessary to take up the challenge. In vino veritas. Although the relevant doctrines go back centuries, they are more vital than ever today as California becomes increasingly crowded and people live in closer proximity to one another. Planned communities have developed to regulate [12 Cal.4th 349] the relationships between neighbors so all may enjoy the reasonable use of their property. Mutual restrictions on the use of property that are binding upon, and enforceable by, all units in a development are becoming ever more common and desirable. We recently confronted the question of what restrictions may reasonably be imposed in a condominium setting. (Nahrstedt v. Lakeside Village Condominium Assn. (1994) 8 Cal.4th 361, 33 Cal.Rptr.2d 63, 878 P.2d 1275.) This case addresses an earlier step in the process, considering how a general plan of restrictions is created in the first place.
