Your deck labor,
costed.

Typically 40-55%. PT decks with mid-contractor are at the lower end (~40%) because materials are cheap. Hardwood (IPE) decks lean lower because materials dominate (35-40% labor). Composite/PVC with mid-contractor is the sweet spot at 45-55%. If your contractor quote is >65% labor, ask why — could be crew tier mismatch, hidden upcharges, or a permit-and-design fee folded in.

Yes, but pick phases wisely. DIY-friendly (difficulty 3-4/10): site prep + layout, fascia/skirting/finishing. Save $300-800. DIY-moderate (5/10): decking install with hidden fasteners — save $1,500-3,000 on a 200 sqft deck but requires patience. DIY-risky (6-7/10): footings + framing + railing — code compliance critical, IRC R507 framing rules unforgiving. Save $2,000-4,500 if done right; if wrong, fail inspection. DIY-hardest (8/10): stairs — most DIYers get rise/run inconsistent. Recommended: DIY site prep + decking + finishing, hire framing + footings + stairs. Saves 30-40% of total labor.

By tier: handyman $35-50/hr (simple PT decks, unlicensed in many states — only suitable for ground-level rectangular decks). Mid-contractor $55-85/hr (licensed in most states, deck-specific experience, sweet spot for typical residential builds). Premium contractor $80-125/hr (licensed + insured, complex multi-level/custom designs, often structural engineering background). Add regional: Northeast/West coast +20-28%, South/Southeast −8%, Midwest baseline. A licensed mid-contractor effectively bills $64-105/hr after regional, $89-149/hr at premium tier in high-cost regions.

Roughly 1-2 hours per square foot for a typical residential build. A 200 sqft PT deck (simple, mid-contractor): ~200-250 total contractor hours across all phases (1.0-1.25 h/sqft). Composite adds ~18%: 235-295 hours. Hardwood adds 50%: 300-375 hours. Phase split (mid-contractor on PT 200 sqft simple deck): site prep 10 hrs, footings 16, framing 40, decking 80, railing 30 (if 60 LF), stairs 10 (if 4 steps), finishing 30 = ~216 hours. Typical project timeline: 1-2 weeks for a 2-3 person crew.

Janka hardness ~3680 — over 3× harder than SYP PT (1000). Every fastener must be pre-drilled (countersunk pilot hole + clearance hole) to avoid splitting + bit failure. Standard composite cut + screw takes ~30 sec per board; IPE cut + pre-drill + countersink + screw takes ~90 sec. Material multiplier 1.50× on decking phase reflects this. Tool wear is also significant — carbide blades dull 3× faster cutting IPE than PT. Most contractors charge a 20-30% labor premium for hardwood decks beyond the time multiplier.

Yes — in 95% of US jurisdictions. Permit costs typically $75-300 (varies by city/county) and triggers IRC compliance inspection at completion. Building without a permit creates resale problems (must disclose to buyers, may need retroactive certification), insurance issues (claims denied for non-permitted structures), and tax implications (some jurisdictions back-tax unpermitted improvements). Permit usually required for: deck >30″ above grade, deck attached to house (ledger connection), deck >200 sqft, any deck with stairs >3 risers. DIY permits are allowed in most states — the homeowner pulls the permit, the homeowner schedules inspections.

First-time DIYer adds 50-100% to professional time estimates. A 200 sqft simple PT deck: pro 200-250 hours (1 week, 3-person crew) → DIY 300-500 hours (3-5 weekends if dedicated, 8-12 weekends typical with family/job constraints). Footings/framing usually take 2-3 weekends. Decking install 2-4 weekends. Railing 1-2 weekends. The hidden cost is your time — at $40/hr opportunity cost, 200 extra DIY hours is $8,000 in 'pay yourself' — sometimes more than hiring contractors. DIY pays best when you're skilled OR genuinely enjoy the process.

Owned: 10″ miter saw ($300), drill/driver ($120), impact driver ($150), level (4-ft + 8-ft), tape measure, framing square, chalk line, ladder. Rented (per weekend): post-hole auger ($75/day), 4-ft transit/laser level ($35/day), compound miter slider ($50/day if you don't own 12″). Material: composite-rated screws or hidden-fastener clip system ($150-300), Simpson joist hangers ($80-200), structural screws (Timberlok or GRK) for ledger. Optional: pneumatic nail gun ($200 + $50/day compressor rental) saves 4-6 hours on framing. Total tool cost for first DIY deck: ~$800-1,400, mostly one-time owned tools.

Required by IRC R507.3 for: decks >60″ above grade (post embedment + footing engineering), decks >400 sqft, any deck supporting >40 psf load (hot tubs, kitchens), decks attached to non-standard framing (post-and-beam, ICF, steel frame), or decks with cantilevers >24″. Engineer fee $400-1,500 for a typical residential deck design. Saves ~$2,000-5,000 in materials by right-sizing beams + posts (most DIY/contractor designs over-engineer to be safe). Insurance/banks may require engineered drawings for high-value homes. Run-of-mill ground-level PT deck on grade: not required.
