I'm planning a free standing deck build off the back of my house but how close to the house can I do the footings? Or can I move the footings away from the house to the circled spots and have a small cantelever and double the joists.
16 inches is ideal for all material, you can canterlever up to 3 ft if you wanted but it all depends on the size and strength of material you use aswell. most suppliers can answer those questions for you too when you shop around.
A ledger is cheaper and better for attaching deck to house then pilings on supporting beams by code must be every 8 feet and at least no more than 2 ft. in from sides ...if yuo must put pilings instead of a ledger allow at least 2 ftt out from house foundation and get 1st call to make sure no lines where you drill.
