@Swetha Solipuram I don't know the answer specifically but I would connect with an architect or an attorney to start.

Before the alderman will meet with you, many ask for the plans with the 4th unit, so you will need an architect first and foremost.This process can be done without an attorney, but it is 100% up to the alderman to approve you and it can be a long process with limited success. 

@Ben McNabb Hey man, I would say an architect (depending how big the project is) and also the city/county.

I'll be working with an outside agent who is familiar with the area.My questions: Does anyone have recommendations for an architect in Oregon that specializes in smaller homes (think cottage/tiny home) - preferably one that is familiar with coastal builds?  

I had to find and interview every party( surveys, architects, realtors, etc.).

Your best bet is to consult an architect. 

I would like to buy cheap plots of land in good locations, have an architect draw of plans for a triple decker (I am in Mass so anything above a 3 unit would require an elevator), finalize through the approval process, and sell the land and drawings to an developer.

You should talk to an architect on the plans.

I am in need of someone that drafts design plans for a renovation..... We are doing a rehab on a single family home in Angelino Heights and need plans drafted before applying for permits with the city. We have a basem...

I have done only duplex and fourplex. would I need architect?
