Adding third unit to duplex? New Hampshire.

[Evan Lowry]

Hello BP gurus,

I have a duplex that's over 3500 square feet, with a large partially finished attic that appears could easily become a third unit, though it will need a fire escape for a second egress.

I would need zoning relief (variance) from the local planning board to become a triplex (there are a few larger multis in the neighborhood), help from an architect on design and code compliance, and a general contractor to build it. I also have a large double lot with plenty of off-street parking, which is a big issue in my area.

Where would I start? Should I be calling an architect first for a consultation, a builder, or a zoning attorney who deals with the planning board regularly? Who would your first call be?

Appreciate anyone pointing me in the right direction as I consider options on my first project of this type.

Thank you!

I would say zoning first, there is no point paying for a design or construction for something you can't legally build.
