Building a 2nd story on my existing home?

Does anyone know what the guidelines are for adding a 2nd story to a house, i.e....foundation, existing walls, etc...? I live in Washington state and could use some advice before I start paying someone to look into it for me to see if it's even worth my time?

for this type of project you cant just have someone advise you over the internet. you will need a engineer to come out look at your existing foundation to see if it can handel the extra weight along with what strutural modifications are needed to handle the extra loads. from there an architect and finally a builder to do the work

Thanks for the replies and I kinda figured that I would need a professional to look at it but I was just trying to get sum pointers b4 I had someone to actually come in to evaluate it all so I didn't get ripped off or charged for something that I didn't need to do bcuz I've heard 2 different solutions to my questions

No one can give you pricing without a working set of plans from which to bid. You can't get a working set of plans without consulting an engineer, architect, and/or builder.

You might be able to find a contractor in your area that has done this type of work that may have a general ballpark figure for you, but EVERY job has it's specifics that affects the overall cost.

I can tell you that I've done two second story additions and the prices were wildly different between one and the other. One required a major structural overhaul before the addition, the other did not. The major overhaul cost nearly 3x the amount that the other did. This is why no one can give you ballparks over the internet. We do not know the specifics of your municipality or structure.

If your house is built on a slab it will probably need little to no structural upgrade. If it's a raised foundation you're going to need at least some upgrades to the underpinnings. The age of your home will also affect costs. An older home (40+ years ) will likely fair better structurally than a newer home. If you're in a seismic zone or a flood zone, this will affect the costs of the addition. There are just too many variables for those of us not in your region to speculate.

Thank you for the input Spruce. I know it's a pretty hard question to answer ****** but just thought it was worth some input from someone with more knowledge than myself. Your reply does help me with some of my questions and I greatly appreciate it.

Thanks again........

Yeah, they implemented some language filters to get rid of some of the spam problems that TOH has.

You're welcome for the ideas. Wish I could help more, but as you can see, there's a lot involved.

Some other factors you may want to think about before taking such a leap would be what housing prices are doing, the value of your home before and after the improvement, and the value of the neighborhood as a whole, which will also affect your homes value. The overall cost of the improvement will very easily reach into the $100K range for a simple straight forward build. Any retrofitting and that number easily doubles or triples.
