One strategy which has been used in some jurisdictions is to require buyers of or tenants in live/work buildings to record an easement which acknowledges the rights of neighboring users -- both within their building or project and in the surrounding neighborhood -- to carry on legal work activities without harassment from the new neighbors. While not ironclad -- for example, the legality of the neighboring use can be disputed, there is a definite value to these so called "nuisance easements" as a tool of disclosure, of acknowledgment of the situation by the signer (something not always emphasized by landlords or developers interested in marketing units), and hopefully serves as a deferment to "imported Nimbyism." Nuisance easements have been employed in Vancouver, B.C. They are intended to be an aid to neighborhood harmony in live/work situations while easing the minds of pre-existing industrial and commercial users and encouraging true live/work use. In Richmond, California and elsewhere, simple disclosure of neighboring industrial uses in the form of language in leases and condominium documents is required.
