When obligations and restrictions imposed in deeds and certain other written agreements meet strict statutory requirements, they are said to “run with the land” and bind successors to the original parties. Other deeds and written agreements that do not meet those statutory requirements are nevertheless enforced as “equitable servitudes” under certain circumstances. The CC&Rs of common interest developments are routinely enforced as equitable servitudes, because the Davis-Stirling Common Interest Act provides that the covenants and restrictions in the declaration shall be enforceable equitable servitudes, unless unreasonable.
