📋 Building Permit
- Adopted code
- Maryland Building Performance Standards (MBPS) based on 2021 IBC, codified at COMAR 09.12.51. Statewide minimum; local jurisdictions had until May 29, 2024 to amend/adopt.
- Permit threshold
- IBC §105.2 governs; storage racks over 5'-9" in height require a permit (IBC §105.2 work exemption ceiling). Baltimore City DHCD confirms rack structural plans/calcs are commonly required and may be submitted with or separate from the main building permit.
- Issuing authority
- Local building dept — Baltimore City DHCD Permits & Code Enforcement; Baltimore County Dept of Permits, Approvals & Inspections (PAI); Montgomery County DPS; Prince George's County DPIE; Howard County DILP.
- Typical fee range
- Baltimore City — published fee schedule (separate PDF); commercial permits commonly run several hundred to low thousands depending on valuation. Baltimore County publishes a flat schedule. Montgomery County uses a Fee Estimator tool keyed to valuation.
- Typical review time
- Published statewide timelines not centrally posted; local AHJs vary. Typical practice is 2–6 weeks for commercial rack work depending on jurisdiction.
🌐 Seismic Requirements
- Seismic Design Category
- B across most of Maryland (Coastal Plain, Piedmont, including Baltimore, Annapolis, DC suburbs). Western MD (Allegany, Garrett counties — closer to Giles County, VA seismic zone and the Appalachian belt) can touch C for some site classes/risk categories
- Sds range
- Baltimore and DC suburbs typically Sds ≈ 0.13–0.18g (Site Class D default). Western MD can reach Sds ≈ 0.20–0.30g near the WV/PA border. Exact values require USGS ASCE 7-22 lookup by coordinates.
- Anchoring & bracing
- ANSI MH16.1-2021 (RMI) per IBC §2209 in SDC B and C. Standard cast-in-place or post-installed anchor bolts in most MD; Western MD SDC C may require enhanced detailing.
🔥 Fire Marshal
- When fire review is triggered
- Maryland adopts NFPA 1 Fire Code (2024 edition, with MD amendments per COMAR Regs .08/.09) — NOT the IFC. NFPA 1 Chapter 34 incorporates NFPA 13 storage protection. High-piled storage triggers at > 500 sf (aisles/access) and > 2,500 sf (8-ft aisles, FD access); commodity classification and rack height drive sprinkler design under NFPA 13. MD State Fire Marshal (under Dept of State Police) has direct statewide enforcement authority, layered over local fire bureaus.
🏛️ Engineer Stamp
- When PE-stamped drawings are required
- Yes. Md. Code Ann. Bus. Occ. & Prof. Title 14 governs; MD-licensed PE seal must include Great Seal of Maryland, name, and license number. MD requires an additional "Professional Certification" statement signed with the seal — unique to MD.
⚠️ Local Quirks
Things that surprise out-of-state buyers in Maryland.
- MD uses NFPA 1, not the IFC — out-of-state engineers regularly miss this.
- MD's "Professional Certification" statement requirement is unusual and rejection-prone — check format before submittal.
- State Fire Marshal has broad direct jurisdiction — even with local FD signoff, SFM can intervene.
- Major logistics corridors: Port of Baltimore + Tradepoint Atlantic (Sparrows Point), BWI airport cargo, I-95 distribution belt; data center build-out in PG County (Beltsville/Bowie) and Howard County is heavy.
- Each county layers its own MBPS amendments via local ordinance — verify county-specific changes at submittal.
