Boarded building
A boarded building has had its doors and windows covered to keep people out. It is one of the most visible signals of distress in a neighbourhood and one of the most reliable in the data.
Why buildings get boarded#
To prevent unauthorised entry, which protects against fire, injury, theft of copper and fixtures, and the building becoming a site for other problems.
An unsecured vacant building deteriorates far faster than a secured one, and it generates complaints, police calls and liability.
Who does it#
The owner, in the ordinary case.
The city, where the owner does not — under its nuisance and vacant building provisions. The cost is billed to the owner, and unpaid it is certified as a special assessment onto the tax bill.
That is the same cost-recovery mechanism that runs through all Minnesota code enforcement, and it means an owner who ignores a boarding order still pays for the boarding, with the charge attached to the property rather than to them.
Boarded is not necessarily condemned#
Two different things that often coincide.
Boarded means secured against entry. A vacant building can be boarded without anyone having declared it unfit.
Condemned means declared unfit for occupancy. A condemned building is frequently also boarded, because it is now empty and needs securing.
Cities are limiting how long#
Boarding was historically treated as an indefinite holding state, and buildings sat boarded for years.
Cities have moved against that, because a boarded building depresses surrounding property values, signals abandonment to a whole block, and rarely improves while it sits.
Minneapolis's 2024 change is the clearest example: properties can remain in the vacant building programme for up to two years, after which they move to prolonged vacancy enforcement with monthly citations of up to $2,000 rather than the annual registration fee.
As a signal#
Boarding is unusually informative for two reasons.
It confirms the building is empty — not just distressed, not just behind on something, but unoccupied.
And it confirms someone judged it needed securing, which distinguishes a building nobody is living in from a building nobody is looking after.
Combined with a registration record, a boarding cost certified as an assessment, and a tax delinquency, it describes a property with a very predictable trajectory — and it does so years before the forfeiture that usually ends it.
Boarding standards#
Cities increasingly specify how boarding must be done, and badly boarded buildings attract their own violations.
Plywood cut to fit the opening rather than nailed across the trim. Secured from inside where possible. Painted to match the building rather than left raw. Some cities require polycarbonate or clear panels on visible elevations, precisely so that a secured building does not announce itself as abandoned to the whole street.
The reasoning is not aesthetic. A building that looks abandoned attracts entry, dumping and further deterioration, and it depresses the value of everything around it. Boarding done properly secures the structure without advertising that nobody is watching it.
For an owner, meeting the standard the first time is cheaper than being ordered to redo it.
