I am adding an apartment onto my house and I need to know what is a good fondation to sit it on and how close to the septic tank can I build it. One more question what comes first the foundation or the plumbing?
I assume you are building the apartment on a slab.The foundation comes first. Check your local building codes. Most require a 4 foot foundation if it is a slab or crawl space. If there is going to be basement, then 8 foot foundation is usually required. As for the proximity to the septic tank, again, local building codes need to be consulted. Don't forget that you will need access to the tank for servicing, such as cleaning. You definitely do not want to cover over the leach field.
i prefer block foundations they are warmer , and easy to repair some rough plumbing comes first usually the excavator will have a limited plumbing license for this, with these type of ?'s i would recommend a general contractor the plumbing is a very basic ?, it will get much more complicated as you go, as a carpenter I give priority to my general as he will always have more work for me, as for homeowners they are confused and disorganized and do not know who to call next, if you do it yourself get all your bids then ask a general for a bid, odds are you left something out so pad your bid at least 15%. good lucxk
