The previous tenant has just left our Grosse Pointe Woods suite. What must happen before our first frozen delivery?

The building owner needs a passed property maintenance inspection, or a certificate of occupancy still within its four-year life, on file with the Building Department. You then complete the Hazardous Chemical Survey and the fire inspection before opening, and the suite should not be listed as a delivery address until the certificate is on file.

A storm has knocked out power to our Detroit office. Should we still accept a frozen carton that day?

Only if a powered freezer is ready for the vials. Wayne County's preparedness pages cover electrical outages, and a placed order leaves Florida as usual, so a practice without power should wait to order until power returns. If a carton is already moving, its tracking number shows your named signer where it is held.

Deep cold is forecast for Detroit next week. Can a carton wait in an unheated Grosse Pointe vestibule?

Bring it in as soon as it arrives. Detroit City Airport highs stayed at 19°F or below from 23 to 31 January 2026, and snow or ice can keep a driver from a door. A carton left outside for hours can be missed by staff or taken, so have the signer move it to frozen storage. A shipper that arrives with its dry ice gone is replaced.

Exosome supply for Detroit and Grosse Pointe practices

When an order reaches a Detroit or Grosse Pointe practice

Frozen cartons ride the Michigan lane into Wayne County within the window the panel above gives. Wayne County Homeland Security and Emergency Management preparedness pages cover floods, heat waves, tornadoes and winter weather, and each can slow the last miles to a Detroit or Grosse Pointe door.

Winter sets most of the timing. Detroit City Airport averages about 112 nights a year at or below freezing. Highs stay at or below 32°F on about 9 December days, 16 January days and 11 February days. A practice that closes for a snow day or a holiday week should plan orders around those dates.

A placed order leaves Florida as usual in a winter storm, so an office expecting to close should order after it reopens. A carton the carrier cannot hand over may be held in its network, where the tracking number shows your named signer its status. A prescription sent to the pharmacy partner is compounded for one patient and travels from Texas as its own parcel, to the practice or the patient. Ask us how a formulation ships.

Cold-chain receiving at a Detroit or Grosse Pointe address

Detroit tests a cold chain in both directions. Detroit City Airport recorded a low of -7°F on 24 January 2026, and 98°F on 15 July and again on 2 September 2026. Name a signer who can take a carton from a vestibule or loading door at once.

Wayne County's preparedness pages cover electrical outages, so confirm that the freezer has power before you accept a delivery after a storm. Open the shipper in a ventilated room, since dry ice gives off carbon dioxide, check that some ice remains, and log the arrival time and lot. The vials then go to the freezer: -20°C long term, 4°C once thawed, following the manufacturer's handling instructions. If a Wayne County delivery turns up with no dry ice left, we send a replacement. Any other late carton may be refunded depending on whether the exosome material stayed temperature-controlled.

Rules that apply to a Detroit or Grosse Pointe order

In the City of Detroit, BSEED licenses only the business types on its list, such as nightclubs, vendors and lodging, and medical offices are not among them. A Detroit practice still confirms zoning first and needs final certificates of occupancy and compliance before opening; BSEED's business page sets out the steps and portal. A new Detroit suite should not be listed as a delivery address until those certificates are in hand.
A new business in the City of Grosse Pointe files a Zoning Compliance and Business Operation form and a business license application with City Hall at 17147 Maumee Avenue. Under Sec. 18-74, a business selling goods there pays $50 a year below 5,000 square feet, and each license runs twelve months from 1 March. A practice that sells no goods should ask City Hall whether the fee applies.
In Grosse Pointe Woods, the Building Department signs the business license application before the City Clerk takes the fee, and the license is renewed every year by 31 March. Medical and dental clinics are among the uses its Commercial Business District rules describe.
When a Grosse Pointe Woods tenant moves out, the building owner must pass a property maintenance inspection or show a valid certificate of occupancy, good for up to four years. No business may open there until a valid certificate is on file with the Building Department.
