We installed one because the previous owner was out of electric for a week with Sandy. 

Welcome @Shon Sandy to BP!

@Sandy UhlmannThere are a lot of factors that go into making such a decision, such as your age, the expected return on investment, current income & tax rates, expected tax rates in retirement, etc.Generally speaking, the longer you will have the account and the higher the rate of return, the more likely you will achieve the desired result, which is access to more after-tax cash in retirement.There are many good calculators out there on the web that can help you get a rough idea of the concept, but a conversation with a licensed professional who will help you look at all of the short term and long term variables is the right way to go.A basic consideration is that the distributable amount in the converted Roth needs to equal or exceed the after-tax distributable amount of the traditional IRA + the personal cash you use to perform the conversion.Converting before the account starts producing higher returns can be to your advantage.  

Re-apply grout to areas requiring (shower corners and floors, mostly) and then using colored silicone to match, finish off all areas requiring soft joints.TRIM: Adjust all interior and exterior doors to latch (80, 84); repair all windows for freedom of movement (81); Replace broken window to kitchen (81)FRAMING: Repair over-notched flooring joists (89)EXTERIOR: Remove soil from wood contact (4,11)PAINT: Touch up baseboards after all polly work, walls and doors.ATTIC / PESTS: trap existing rodent infestation using cages, clean out all contaminants, seal off entry points (68) GROUNDS: Replace rotted wood (2), Add drip edge and replace piece of damaged wood behind HVAC unit (6); replace rotted corner boards (7); replace damaged siding and paint, as well as siding screws and loose soffit (9)

If quakes go for long, and building codes change, 90% of the time you are "grandfathered" and will not be entitled to improve the properties.Yes, we do not have basements here, due to the fact that CMU basement walls when hit by lateral quakes are easy to break and water/soil penetrates them.

Until Sandy hit, power went out, basement got completely flooded and ruined my furniture.

Air samples, soil samples...cant go on making speculations without data. 

First, fix the water drainage issue. the leader pipe should be put into a drainage pipe and brought away from the structure, there is water just dumping down and probably causing some soil erosion, which could effect the slab. make sure all water drains away from the structure. if its concrete, have a Mason take a look at it and see if there is anything he can do with it.

Also would I ever have to do a soil test if the garage was used for a business?

There are many main thoroughfares to get out there (Powell, Division, Stark, Burnside, Glisan, I-84 and Sandy) and there is a MAX station in downtown Gresham.
