Depending on the scope of the exterior work, it may be beneficial to hire a local architect that is familiar with the specifics of the local requirements.... and they may have contacts to help ensure the review and close-out process goes smoothly. 

@Mandi Lambert I am an architect by trade so have asked the same questions.

My uncle and I talk about his blueprint because he’s an architect.

I don't do that type of work (usually done by Architect), but they don't usually allow the max unless you are either matching your neighbors, or have a lot of room on the sides.

Are you an architect with a design vision?

Something to think about for next time I guess.I suggest you get an architect or draftsman in to look at this and see what ides they can come up with to eliminate the issue or at least improve it.

As my attorney explained in an analogy, "if you are an architect, and work for an architectural firm, the blueprints the employee creates are the property of the client and/or the architectural firm.

On the other hand, if you or a team member like your GC or architect has all the skills and contacts to get things through as smoothly as it possibly can with LADBS (which is never perfectly smooth of course), than you have your advantage.

Check to see if you have to install any manholes, fire hydrants, curb, gutter, sidewalks, street signs, street lighting any specific street design or access requirements, Check DOT requirements for access, stop lights and permits, traffic studies, DWQ requirements for permits, permit fees and time frames.Once you have an idea of what you can build and what is required in terms of permitting and infrastructure you want to talk to some civil engineers, architects and commercial general contractors that do the type of projects and build the type of buildings you want to build so you can get an idea of costs, time frame and requirements.

@Daniel Johnson ill send you the architect I've been using and you can let me know what your current lot coverage is and how much space you have and ill let you know (from my current experience) what they'll allow.
