Deck and porch stairs

The total rise, the run you have, and what the stairs land on.

• Attach your Sheet so people see your sizes and the math.
• Your town is enough. Never your address; check photos for house numbers and plates.
• Is it safe? A safety question here goes to pros verified in general contracting or carpentry, unless you pick another trade. Only they can call it safe or unsafe.

Stairs for a 3′ rise: 5 risers of 7-3/16″, 4 treads and 3 stringers (2×12 × 8′), checked against the stair code.

What people get wrong:

• Forgetting to drop the stringer. The bottom step ends up 1″ taller than the rest.
• Measuring the rise at the deck edge. Ground slopes.
• Over-cutting the notches. Running the circular saw past the line cuts into the stringer’s strength.
