The Short Answer
Any attached deck in Marina requires a permit. Marina's coastal location means stricter ledger-flashing rules, salt-spray corrosion protection, and no frost-depth exemptions — you'll need plan review and three inspections.
Marina's waterfront position sets it apart from inland Bay Area cities: the Building Department enforces California Coastal Commission deference on many projects, and the Marina Municipal Code requires ledger flashing details that meet or exceed IRC R507.9 with specific corrosion-resistant fasteners (stainless steel or hot-dipped galvanized, not standard galvanized). Frost depth is negligible on the coast — footings need 12 inches minimum below finished grade for drainage, not frost-load depth — but the sandy/salt-spray soil requires concrete footings in post holes, not wood piers. Marina also uses the 2022 California Building Code, which includes salt-air durability amendments. Any attached deck, regardless of size, triggers structural review because the ledger attachment is the critical failure point in a coastal environment. The Planning Department may also flag your project if it's within 100 feet of Dunes Drive or the bay — coastal setback overlays apply. Expect 3–4 weeks for plan review, not the typical 2 weeks.

What happens if you skip the permit (and you needed one)

Marina attached deck permits — the key details

Marina requires a permit for any attached deck, no exemptions for size or height. The trigger is structural attachment to the house — the ledger board connection — which makes it an alteration of the primary structure. The City of Marina Building Department, part of the City Manager's office, enforces the 2022 California Building Code with local amendments. The most critical rule is IRC R507.9, which governs ledger flashing and fastener spacing (16 inches on center, stainless steel bolts). Marina's Coastal Zone rules add a requirement: all fasteners, flashing, and connectors must be 316-grade stainless steel or hot-dipped galvanized to resist salt spray. Standard galvanized bolts corrode in 2–3 years in Marina's climate and fail under wind load. The Building Department's plan-review checklist explicitly lists 'corrosion-resistant fastener specification' and 'ledger flashing detail with drainage plane.' You'll need a set of plans stamped by a California-licensed engineer or architect if the deck is over 200 square feet or sits higher than 4 feet above grade; smaller or lower decks may qualify for over-the-counter review with simplified details.

Every project is different.
