Hire an architect + owner build, OR hire an expensive GC?

[Benjie DeVera]

I was wondering if anyone can advise me whether or not I will need an architect. I have a project in Glendale, CA in which I am hoping to add square footage and a full bathroom. Given that it's in Glendale, I've only heard that they are strict. 

To save some money, I was thinking of having the owner-build permit. If I do, will the City Planning Department be asking me for drawings and blueprints (which I cannot produce)?? 

Am I better off to hire an architect and have them draft the drawings, and then have a very good, experienced handyman/build (without license) to execute the projects and drawings? I can be at the property to manage and be present as inspections are needed.

Or does anyone have any other thoughts on how to save $$ than hiring a General Contractor (GC) who are usually expensive (up to 4 times more than an unlicensed contractor)?

Any tips on this renovation subject is greatly appreciated! Thanks!
