Build beyond the maximum square footage?

[Jeremy Segermeister]

I’m looking to build a custom home in the Bay Area. I have an amazing lot identified that I was ready to pull the trigger on. Unfortunately during my due diligence phase, I learned the maximum square footage allowed on this lot is 2400 sqft (including the garage). 7900 square foot lot, 30% max or 2400 sqft, whichever is greater.

This was quite disappointing because a 2,000 square foot house is too small for our forever home.

Does anyone have any creative ideas to go beyond this? I'm looking into the new ADU rules to see if they can help.

How did you come to the 2400 SF quantity? Is this maximum gross SF including EVERYTHING? You may want to retain an architect (or ask your architect). Here in NY, the Code eliminates several spaces which are not calculated in the habitable SF calculations. Basement, boiler room, storage, even closets and means of circulation (stairs) are not counted towards habitable square footage calculations. This could be the difference of a few hundred SF in your favor. @Jeremy Segermeister
