I'm looking at building a 150 square foot workshop / storage building in the backyard. It won't need power or plumbing for what I'm doing and as long as it's at least 5-ft from the house or property line, no permit is required. Otherwise, it would add $700 to my annual property tax bill, which is would be more than the shed would be worth to me.
Next step would be to connect it to an existing door to the house with something that the city would not labeled a "structure" but would let me go in and out without opening either one to bugs, etc.
Any ideas about how to make some kind of connection like this and still be legal?
