Maximum lean for building
Maximum lean for building
(OP)
I am looking at a two story residential structure that has extreme lean or tilt to one side. Client is fighting a preservation board which wants the building repaired (at a high cost) were as the client wants to demolish the building. I feel the building is a hazard, as the lean or tilt is 1-2 feet out of plumb over the two stories. Does anyone know of references that might specify a maximum departure from plumb for a building before it can be deemed dangerous or a hazard?

Folks nowadays build brand new buildings that lean all over the place intentionally. If the structure's light, has enough shear resistance, and isn't sinking into the ground, it may not be a deal breaker. Much depends on the cause of the lean though.
I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

Approximately what age?
What is the building material?
Plan dimensions and/or general description o fate plan layout?
Are the floors level?
Do you have a diagnosis of the cause of the out of plumb conditions?
I'd look at the overturning moment vs. whatever is in place to resist overturning.
Regardless, 1 to 2 feet out of plumb over two stories seems pretty drastic!

My thanks; A most practical guideline, with a real world reference! A star for your troubles...

This standard has a.o. about 30 pages of sketches and tolerances that can (mostly) be readily applied in real life situations.
Thx for the LPS...

I would think that a lack of lateral bracing (a likely/common shortcoming in 1920's wood frame garages) is a "concern", regardless of whether there is settlement.

Have the wood tested and assessed for Lacrymans (dry) and Coniform (wet) and the extent of same. If the extent is past 30% of the bottom of the structure it is not repairable without demolition as the result cannot possibly achieve a 50 year design life.
