Rental registration and inspection
Under Columbia's Rental Unit Conservation Law, every rental unit in the city must hold a Certificate of Compliance showing it meets the licensing, zoning and property maintenance codes.
For investors: Ask the seller for each unit's current Certificate of Compliance before closing, since operating any Columbia rental without one is unlawful. City inspectors or police looking into an occupancy complaint can ask to see it, together with the tenants' signed occupancy notice.

Since January 1, 2025, Columbia rental certificates last five years with an inspection at each renewal; fees are $130 per single-family home, $195 per duplex and $70 per unit up to 30 units.
For investors: With a five-year term, a buyer's first Columbia inspection may arrive at the seller's renewal date rather than at closing, so ask when the current certificate expires. Buildings with more than 30 units pay a lower $50 per unit rate.

When a Columbia rental is sold, its certificate can be transferred to the buyer for $15 within 90 days of the title transfer, covering the rest of its term.
For investors: Put the 90-day window on the post-closing checklist: filing the $15 transfer in time keeps the seller's remaining certificate term instead of paying a full fee and booking a new inspection. Short-term rental approvals work differently and end when the property sells.
