Maryland climate, soil, seismic & hydrologic drivers
- Frost-line trench depth: 30-inch design minimum for buried footings
- Dominant residential foundation type: Full basement — dominant in Upper Midwest, Northeast, and Mid-Atlantic on freeze-thaw + radon-zone-1 sites
- Expansive soil risk: Low — sandy or stable subsoil, standard slab-on-grade design
- Seismic design category (ASCE 7-22): SDC B — minor seismic risk, standard tie-down requirements
- Hurricane wind tier: Moderate — 110-140 mph design wind, standard tie-down

How foundation pour costs vary in Maryland
State-specific code or insurance rule: Maryland Home Improvement Commission (MHIC) Code §8-101 requires every Maryland foundation contractor to hold an MHIC Home Improvement Contractor license — one of the lowest-threshold mandatory contractor licensing schemes in the country at $500 contract value, with MHIC Guaranty Fund compensating homeowners up to $30,000 per project for MHIC-contractor abandonment, and Maryland Critical Area Act §8-1808 separately restricts foundation excavation, grading, and impervious-surface coverage on every Chesapeake Bay watershed residential pour within 1,000 feet of mean tidal elevation, the most restrictive coastal-buffer foundation regulation in the Mid-Atlantic.
