Too many variables.
Have you checked with the City? Is it allowed? Will you have to do additional site work to add parking?
Will it require sprinklers?
What material for outside walls? Masonry, steel stud and stucco, other?
What type of roof?
Are you including any light and/or power in your definition of shell?
How about a bathroom or just extension of plumbing?
Is the addition to the front, side or rear of the building?
The entire building will probably have to be brought up to code, do you also include that in the price?

Painting over old lead paint does not "cure" it. The lead paint is still there, under the layers of top coat. The main problem with it, is if it flakes, that's when it can produce particles. I recommend you take a look at the governments free booklet,www2.epa.gov/lead. regarding lead in your home. Make sure you understand everything about the issue before moving forward.... more
Great advice from everyone else on this...My feeling is you never know how much a remodel will cost until it is done! I know that isnt helpful so here is some information for you.
The big variables are where you live, the design, how much work you will do yourself and the materials you select. If you live in a rural - low cost area the price for your addition will be less than 1/2 of what you would pay in Manhattan, etc. Materails - same thing you can pay $30 for a faucet or $300???? And there are a lot of these material decisions in a bathroom. The 2nd story adds another variable especially in CA where the first story needs to hold up the 2nd in case of an earthquake so the existing structure may need a lot of reinforcement.
Having said all that there is no reason why you should not get a ballpark and that ballpark is $250 a square foot...plus or minus $100 a square foot (sorry for such a big range) I got that from the website RemodelOrMove.com which has a free to use online calculator for people who just want a ballpark estimate of remodeling costs. I pasted the numbers i got from the calculator below.

Korea Town is a sought-after area but it's impossible to know how much to spend on renovations without knowing what's needed and whether or not you plan to hold on to the property after fixing it up or to sell it. If you'll contact me with more information, I'd be happy to tell you what I think. I hope this helps.
