How do I make sure my footings pass the first inspection in the city?

Footings in that red clay are a pain, but the inspector is mainly looking for depth and a clean, undisturbed bottom. In Atlanta, you generaly need to hit 12 inches deep to get below the frost line, but verify your specific permit becuase some guys want 18 or even 24 inches depending on the deck height and load. If you're worried about width, **belling out** the bottom of the hole is the way to go. It increases the bearing capacity without making you dig a massive crater. Just make sure there is no loose soil sitting at the bottom when they show up for the hole inspection. For the ledger, do not guess on the bolt spacing. Most local codes follow the DCA6 table strictly. If you're using 1/2 inch lag screws or thru-bolts, you're looking at a staggered pattern—one high, one low—roughly every 12 to 16 inches depending on how long your joists are spanning. Whatever you do, don't put them in a straight horizontal line or you risk splitting the house rim joist. And make sure you have that **Z-flashing** tucked behind the house siding and over the top of the ledger. If they see water can get behind that board, they will fail you imediately.

Those 80lb bags of high-strength mix are perfectly fine. They usally don't care about the exact brand as long as it's rated for at least 3000 PSI. What they actualy watch for is that you aren't souping it up with too much water, wich weakens the pour. Keep it a thick consistency. Sometimes they'll ask to see the empty bags to verify the rating, so keep a few stacked near the work area just in case. Focus heavily on your hardware. Use the specific **connector nails** meant for your joist hangers rather than structural screws unless the hanger is specifically rated for them. Inspectors around here hate seeing gold screws in joist hangers. If you follow the approved plans and have your hardware right, the inspections are usually over in ten minutes.

Spot on about the hardware and the flashing. To add to that, double-check if your permit requires lateral load connectors. In Atlanta, alot of inspectors won't sign off on the framing unless you have those tension ties installed to prevent the deck from pulling away from the house. Also, when you're clearing the red clay out of those holes, grab a shop vac. It’s the easiest way to get that last bit of loose dirt out so the bottom is truly undisturbed like they want to see. It beats trying to scoop it out with a shovel once you're three feet down.

Wait, what exactly is a lateral load connector? I’m still trying to figure out which joist hangers to buy, so I’m definitely a bit lost on the more advanced hardware. Is that somethig that goes on the inside of the house or just the outside?

Also, for the "belling out" part for the footers, do I need a special tool for that or just a regular shovel? I’m worried about making the hole too big and having to buy way more of those 80lb bags than I alredy have. I'm really new to this and don't want to mess up the very first step.

Whoa, seeing this progress is getting me so hyped to finish my own project! I’m still in the dreaming phase while I clear my yard, but I have to ask—since you're building in Atlanta, are you planning on adding a pergola or some kind of shade structure later? I’m terrified of the summer heat melting me out there! Also, does anyone know if adding a built-in bench counts toward the square footage for the permit, or is that considered furniture? I want to maximize my space without making the inspector come back a fifth time!

Back in my day, we didn’t have these DTT2 tension ties; we just over-built the ledger and moved on. If you're stuck on the lateral load thing, just know it usally means you're going inside the house to pull back some drywall or insulation. You've gotta bolt those connectors directly to the floor joists inside. It’s a mess but that’s the code now.

Also, watch your flashing material. If you bought that modern ACQ treated lumber, don't use regular aluminum flashing. The chemicals in the wood will eat holes in it faster than you'd think. Use copper or high-grade stainless. I’ve seen 'permanent' decks rot out in five years becasue of a bad metal reaction.
