See what is possible thru Special Use or Variance permits.4. 

I would guess many government workers are renters like law enforcement and state department as they rotate in and out of the field offices to DC.

My second house was under contract before it was even listed, but the combination of my GC disappearing and having to restart the permitting process for the carport in March right at the start of Corona lock downs dragged that out and eventually feel out of contract.

Hi @Carlos Rodrigues,Realistically, it's unlikely that sellers will get permits while in escrow.

It also says under the accessory uses section: "nonhabitable structure requiring a building permit." 

Quote from @Ana Mills: The high quotes for the electricians will be way cheaper than having your handyman do it and it causing damage, causing a fire, or even worse causing a fire later when someone is living there and that person/persons getting hurt because of the work being done by an unlicensed worker doing the work. 

Most of my renters are nurses, engineers, and tax payer funded employees (Government workers). 

I know for myself and other investors they have had situations where someone in the building department says something verbally but then when you go to get the permits or approval things have changed.

Make sure any renovations comply with local regulations and obtain the necessary permits if plumbing changes are involved.

Similar areas that have legal under utilized permitted space convert to max studios that you can fit.
