If a landlord raises the rent on a 400 square foot space, they're simply asking more money for it the same space. If a tenant wants to pay that price for 400 square feet, that's his choice.
On the other hand, if the landlord claims it's 420 square feet, no matter how much he charges per square foot, the tenant is paying for something that simply doesn't exist.
I get the semantic dishonesty, but not the practical issue.
In practice, though, total moot point: the last time I looked for office space (earlier this year), the first agent I called sent me scaled floor plans for over 100 places. There were rsf numbers to go with them, but the dimensions of every office were right there.
Lying about the objectively measurable characteristics of your product is wrong.

Sorry I managed to offend you, but you work in a field that tends towards grey areas, so maybe invest in some thicker skin. (Hey, look at my field!)

I find it offensive because you're wrong and the people here are modding you up. I'm not crying into my soup or anything.
Thanks for your caring comment though.
Besides, who rents based on a sqft number? You always visit and work out the space before signing. It's not eBay!
