City fine on addition without a permit

[Amador Abreu]

Dear beloved community 

I would like to reach out to see if any of you have gone through the same experience and I am looking for any kind of support on next steps.
I would love to see if any of you are in the Seattle area, which will be even more helpful.

I bought this property in a good location in an auction. The house had 2 additions. One extending the kitchen by 5 feet and another adding what we called a large shed 30" wide 12" deep attached to the daylight basement holding 2 bedrooms.

As the city says, when i bought the house i bought the issues with it.

While refinancing this year, I was rejected due to mismatch between the number of rooms in the city and in the actual house. 
Knowing to be a problem I would carry all around and I would not be able to sell in the future, I reached out to the city to normalize the situation. I was received with a lovely and gentle Code Violation and I am in a place now that I have never been before.

The process of making my house current requires drawings and qualified professionals to tell me what I need to do to bring the house to code. It is a stressful list of requirements that I feel I need a ton of help.

Here are few questions to you guys:

1) have you been in the place before? What did you do? How much was your cost?
2) I have been doing the drawings myself with Sketchup but I am not a structural engineer and I cannot say what is in code or not. Do you recommend I go to a bigger company that will have everything that is needed? or should I engage with a structural engineer than with the next professional required? I have found a big company in the seattle area and they are charging me $2500.00 just to tell me what I need to do. I have found a retired builder that would do the design project for $5,000. Then I will have to do the actual work. I am quite nervous  about the costs with this project so I m reaching out to people to see if they have been there and if they have something I could learn.

I appreciate all the support we give each other here and you guys are on my list for thanksgiving!! :-)

Thanks
