Deck Build Tool List - What's Worth the Splurge?

Hey everyone, I'm about to build a 16x20 deck off my back porch. I've got the basic stuff (circular saw, drill, level) but I want to do it right. What specialty tools should I consider buying or renting? I'm thinking about a nail gun, maybe a miter saw? Any advice would be awesome.

Congrats on the project! I've built dozens of decks over the years. If you're doing pressure-treated lumber, a good quality framing nailer is a must. It'll save you hours and your arm won't feel like it's gonna fall off. For the decking, a pneumatic coil siding nailer with the right ring-shank nails is the way to go. Also, grab a laser level for laying out the posts and checking the beam height- it's a game changer.

If I had to pick one splurge, it's the nail gun. It's worth every penny.

I'm all about precision, so I can't stress enough: get a good miter saw with a sliding compound feature. You'll need it for cutting the railing and stair stringers to exact angles. And don't forget a tape measure with a 16-foot stand-out; trust me, it makes solo measuring a lot less frustrating.

Also, consider renting a plate joiner or biscuit joiner if you're using composite decking - it helps with hidden fasteners. But if you're going with wood, a simple jig for deck screws works fine.

I'm a woodworking hobbyist, not a pro, but I've done a few decks. One tool that surprised me was the oscillating multi-tool. You'll need it for trimming the ends of the decking to match the existing structure, and for small cutouts around posts or stairs. It's also super handy for cutting off nails flush.

And don't underestimate a good circular saw with a fine-tooth blade for cutting PT lumber cleanly. The combination of a saw guide (like a straight edge clamp) will save you from wonky cuts.

What about a power planer? I heard you need one to level the decking boards if they're warped. Also, is a router necessary for the edges? I'm just a beginner, so I'm trying to keep costs down.
