ℹ️ Permit required. Any attached deck or deck over 30″ above grade in Maryland needs a permit. We pull all permits in our name.
🔧 Ledger attachment. Requires proper flashing + through-bolt per IRC R507. Most common deck failure point.
⬆️ High deck. Over 4 ft requires engineered guardrail. Maryland frost line 30″ — footings must go deeper.
♨️ Hot tub = structural engineering. Free structural assessment included with consultation.
🏛️ Attached pergola may need additional permit category. We handle all filings.
📐 Complex shape. May require engineered drawings in some MD counties.
⚙️ Trex Elevations steel framing. We are certified Trex Elevations installers.
❄️ MD snow load: 25–40 psf. All decks framed to meet local snow load.
