I agree - I only meant reasonable in relation to typical home sizes.

If there's a grand old 6 bedroom house in a downtown area, it would probably make sense to allow 6 unrelated tenants. My only concern there would be homeowners subdividing rooms ad infinitum to get more tenants. But, there are probably solutions to that that don't involve arbitrary caps on household size.

Sure, like I mentioned in my post above it could be based on square feet. Or the number of toilets. Or bedrooms with windows. Or any number of other things and I would be sympathetic.

It just drives me nuts that the average local politician doesn't seem to care about carefully designing regulations or pruning back the near endless stack of existing, poorly design regulations. We've been stacking stupid on stupid for more than 100 years and it makes doing anything in the real world (building a house, running a local business, etc...) pointlessly tortuous.

Or, you could let people decide how large a bedroom they are willing to rent and stop micromanaging/over-regulating every bit of real estate, which is why the costs are too high.

Normally the rules for minimum square footage for a "bedroom" and the requirement for a window would limit the amount of internal room dividing that could happen.
