What MEP Systems Does a Dry Cleaner Require?

Dry cleaner MEP design covers the ventilation, plumbing, gas, and electrical systems for solvent-based garment cleaning and finishing. The package typically includes dedicated exhaust for dry cleaning machines and solvent vapors, boiler and steam distribution for presses, make-up air to balance the exhaust, gas service sized for boilers and dryers, electrical distribution for the heavy equipment loads, plumbing with solvent-resistant waste handling, and spill containment per environmental and fire codes. The tenant-improvement trap is real here: the space looks like retail, but the systems are industrial. Before signing a lease, I want the owner to know whether the building can even serve the loads — gas capacity, electrical service size, and a path to the roof for exhaust. Finding out after the lease is signed is an expensive education.

Ventilation leads: machine exhaust for solvent vapors, general exhaust for the production area, and make-up air sized to match — a dry cleaner exhausts a lot of air, and the building has to replace it without going negative and pulling in unconditioned air through every crack. The boiler plant follows: gas-fired boiler, steam and condensate distribution to the presses, combustion air, flue routing, and water treatment. Electrical has to carry the connected load of washers, dryers, presses, boilers, and HVAC — often far more than the retail service the space was built with. Plumbing includes water for the boiler and wet processes, floor drains, and waste handling that keeps solvents out of the sanitary sewer per local pretreatment rules. Spill containment — curbed areas, sealed floors, solvent storage per fire code — protects the building and the groundwater below it. And because dry cleaners usually sit in multi-tenant buildings, odor and vapor isolation from neighbors is a design requirement, not a courtesy.

Solvent type matters — perc machines carry stricter rules than some alternatives. Plant size and same-day production volume drive equipment counts. And existing-building conversions live or die on what the base building can provide. Get the equipment list and the base building's capacities on the table before design starts.

• Solvent type: perc vs. hydrocarbon vs. wet cleaning changes ventilation and containment rules
• Production volume: same-day and high-volume plants need more machines and bigger utilities
• Base building limits: gas, electrical, and roof access in conversions often need upgrades
• Neighboring tenants: food, medical, or residential neighbors raise the bar on vapor isolation
• Environmental history: solvent spills are legacy liabilities — Phase I/II findings affect the project
