Janitorial Expenses - Looking for Cost Benchmarks

[Jeff G.]

Looking for some benchmarks/guidance regarding typical janitorial expense for a small office building in greater Boston.  We own a 14,000 sf multi-tenant office building.  Purchased it vacant.  Renovated it and now have tenants moving in.  We have gotten a couple bids for cleaning 5 times per week, with trash removal (we do not have dumpster on site).  The building has 6 bathrooms and 2 kitchens.  The quotes I have gotten are for approximately $700 to $800 per week.  That is equal to about $2.50/sf per year.  That feels very heavy.  Does anyone have any insight on this that they can provide?  Thanks!
