I would just like to add that I don't believe there is a one size fits all solution nor one supreme option that stands above the rest. 

@Jim AdrianWe use a fail amount of polyurethane foam, but have found it is not always the best solution for older properties (Edwardian or earlier).

(Search for "map app Portland to find if that location is in the zone.)Some small developers and I met with 4 members of the Planning and Sustainability Commission yesterday to urge them to allow up to a 4-plex in R5, expand the housing opportunity zone to all areas of Portland, and to increase the proposed allowable FAR (floor area ratio) to at least 1.0 (current FAR in the RIP would only allow a .5 FAR, or a total of 2,500 square feet of building area for a 5,000 square foot R5 lot).

I would appreciate any ideas anyone might have on a solution to my dilemma.Shawn

Use an attorney and make sure your are protected if the client never is able to sustain employment. 

I have an IT services company and a phone system sales and service company in the building, so I can offer a pretty comprehensive "complete office solution."

I really appreciate your answers and I realize I'm not going to get a definite, concrete solution online like I would at a consult.

We examined this issue extensively and decided that it wasn't something that could be implemented in a manner that would have any value.That said, you can quickly and easily see all forum posts from any user by going to:http://www.biggerpockets.com/posts/user/USERNAMEMost power users of the site typically keep an eye on their dashboard forum feed to see those topics that have come up of interest to them, or if interested in a particular user, go to the page with all their posts.That all said, if the brain trust here has some kind of solution to the forum issue I described above, I'm more than happy to listen.Thanks for the post -- I tried to answer as best I could.

Get three estimates from foundation companies and then get a verbal from a structural engineer to ensure the solutions proposed are good and there's not a simpler or better way to fix the issue.
