DIY vs. Hiring a Pro
DIY Considerations
- Simple ground-level decks are a common DIY project
- If you have carpentry experience, you can save thousands on labor
- You are still responsible for pulling the permit and meeting code
Hire a Professional
- Elevated or multi-level decks require structural engineering knowledge
- Professionals know local code requirements and pass inspections efficiently
- Licensed contractors typically include permit handling in their scope
- Proper footings and connections to the house are critical for safety
Our recommendation
A small, ground-level deck is a realistic DIY project if you pull the permit and follow code. For elevated decks, multi-level builds, or anything attached to the house, hire a licensed contractor for safety and code compliance.
