By national ratios Baltimore supports about 1,000 full-time plumber pros — a large market with room for niche specialists, emergency-only operators and franchises alike. That is larger than most United States cities we cover. Ownership is split — 48 % owner-occupied — so a typical week mixes homeowners with landlords and property managers who buy in volume. The housing stock is old for the country, which pushes repair and replacement demand above the national average.
