RE: 14 story concrete shear wall building re

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Roger,

Where are the bodies?  Being serious, this section allows a building
department to shut down crack houses and teen sex ranches when someone calls
the Mayor.  Also it gives a building department some methods of determining
when existing buildings are public hazards.  

I know that in my jurisdiction we do not go around kicking people out of 50
year old houses that are sitting on tree stumps unless they are public
nuisances. 

I am just a spectator for the whole thing and wonder whether any big cities
have used the 'Uniform Code for the Abatement of Dangerous Buildings Section
302.14 Paragraph 14' to require an old building to be seismically
retrofitted.

Scott,

This is a very ambiguous section that will permit anyone to argue that a 
building is not dangerous even if the building violates all 18 criteria!

While on first blush, it appears that the 18 items each define a dangerous 
building, the first paragraph,

"For the purpose of this code, any building or structure which has any or
all 
of the conditions or defects hereinafter described shall be deemed to be a 
dangerous building, ***provided that such conditions or defects exist to the

extent that the life, health, property or safety of the public or its 
occupants are endangered.***" [emphasis added]

contradicts the rest of the section.

It seems that it boils down to the Building Official saying that a building 
violates one or more of the criteria and therefore it is a dangerous 
building, and the owner, if he/she doesn't want to correct the problem,
says, 
no, the building has stood for so long and it is not endangering anyone.

This is wording that lawyers love!
