You need to have architectural plans drawn up and then submit those plans to the local building department for permits.Hiring an expeditor is not necessary.

It allows home and building owners to obtain a permit to repair or replace existing features of a building or make minor modifications without providing architectural plans.

I leaned on contacts in CRE, our team leader in residential, construction, architecture, tax planning and more.

I have architectural design but it's not engineered. 

Just don't forget that then you will pretty need to get a construction permit from the town with architectural drawings, etc. 

Hi BP Community,As part of mine and my wife's investment strategy, I gave up my W2 safety net to launch my own architectural firm.

Which does mean that you'll be paying for drawings/architectural services for something that could potentially take months.And my project truly has taken months, waiting on various city department reviews and responses.In terms of your question of the ARV with no neighborhood comps --  I would look at it as adding a bed and a bath to the total lot count, and seeing if there are any comps (as opposed to an exact unit match).That being said, could you simply add that 300 sq ft to one of the existing units (extra bed and bath) to avoid the adjustment altogether?

Hi Cory, One of my favorite local architectural firms based on Phoenix is Studio MA right off Indian School Road in Arcadia.

I am skilled in rough and finish carpentry, drywall, electrical, interior design and light architectural renovations having spent my career in design/build, theater/film sets, and also assisting friends with small home design projects. 

Either way, you need architectural designs and structural engineering along with LID, title 24, and other items submitted to Building and Safety for plan check review.
