Weight load in a house?

Question

My mother has an absolute fear about too many people in her house at one time. Here are specifics of her home. Can anyone tell me what should be a safe amount of people in her house at one time. With Thanksgiving approaching she is already panicked. We are expecting about 24 people for dinner.
What is a normal "people load" for a house with the below specifics:

Tudor home 1.5 Story (Brick Exterior)
Built in 1943
Lot dimensions: 25 x 125
Dimensions of the rooms on the main floor are as follows:
Living room = 12 x 30
Dining room = 12 x 12
Kitchen = 10 x 13
Family Room = 14 x 11
Bedroom 1 = 10 x 13
Bedroom 2 = 10 x 12

I know that you can't speak to the soundness of this specific home, BUT if you can just give us some typical guidelines that might apply, we would all be forever grateful...(all 24 of us).
Very best regards, Rdhead500

Answer 1

I think mom needs some help. A house even of that age will hold as many people as you can fit in it. Just tell her that all of the walls,carpeting,furniture,plaster/drywall, roof weigh a little more than a house full of people.

Answer 2

WOWEE !
Where do you make the kiddies eat?
As a rule of thumb, I would say,only invite as many people as can be comfortably seated at the dinning room table.
