What happens if you skip the permit (and you needed one)
- Stop-work orders and $500–$1,500 fines from Annapolis Building Department; double permit fees required if work is found unpermitted and must be re-pulled.
- Insurance claim denial: homeowners policies often exclude unpermitted work; a deck collapse injury claim could be rejected entirely, leaving you liable out-of-pocket ($250,000+ litigation exposure).
- Resale disclosure hit: Maryland real-estate transfer taxes and the Property Condition Disclosure Statement require you to flag unpermitted decks; buyers routinely demand removal or permit-after-the-fact, which costs 150% of the original permit fee.
- Lender/refinance blocking: if you refinance or apply for a HELOC, appraisers flag unpermitted decks and lenders refuse to close until permit is obtained or structure is removed.
Annapolis attached-deck permits — the key details
Annapolis Building Department requires a permit for any deck attached to a house, even a 4x6 platform. The triggering rule is IRC R105.2(a), which exempts only detached (freestanding) decks under 200 square feet and under 30 inches above grade from the permit requirement; because your deck is attached — meaning it is anchored to the house via a ledger board — it falls outside that exemption automatically. The city's online permit application asks for deck size, height, materials, and footing depth. Plan-review staff focus on three things: (1) ledger-board flashing details that comply with IRC R507.9 (the ledger flashing is the single most-failed detail on Annapolis deck inspections, because Piedmont clay soils and high water tables mean water infiltration kills rim joists in 5-7 years if flashing is undersized or improperly sealed); (2) footing depth: 30 inches below finished grade is the Anne Arundel County standard (Maryland Building Performance Standards, 2023 edition, Section 1809.5); (3) guardrail height of 36 inches measured from the deck surface to the top of the rail (IRC R312.1, per IBC 1015). Stairs are required if your deck is over 30 inches above grade; stair stringers must support a 300-pound concentrated load at the center of the tread, and landing depth must be at least 36 inches (IRC R311.7.1). If your deck includes electrical outlets, a switch, or lighting, you will need a separate electrical permit and an electrician licensed in Maryland; outlets on decks must be GFCI-protected and inspected by the county electrical inspector. Plumbing (hot tubs, drainage) requires its own plumbing permit.
