Final answer:
Lynn's septic system situation is considered a nonconforming use, which means it was lawful before new zoning laws but doesn't comply with current standards.
Step-by-step explanation:
Lynn's situation with a septic system that isn't large enough to serve her home in Minnesota is considered a nonconforming use. This term is used in zoning law to describe an existing property condition that doesn't comply with current zoning requirements but is allowed because the structure or use was lawful before the new zoning law was passed. An encumbrance is a general term for any claim against a property that may restrict its use or transferability, like mortgages or easements, but does not specifically refer to a condition like Lynn's. Meanwhile, an easement is the right to use someone else's land for a specific purpose and wouldn’t apply in this context. Lastly, a lien is a claim made on a property to satisfy a debt or protect a claim for payment of a debt, which again, is not the issue Lynn is facing.
