Frequently Asked Questions
Common delays?
Missed inspections (plumbing, electrical, fire). Zoning compliance issues. Accessibility issues. Unfinished punch list items inspector sees. Each adds 3-10 days per round.
Temporary CO?
Temporary/partial CO allows limited occupancy while work continues. Typical 60-90 day duration. Good for mixed-use or phased occupancy. Not all jurisdictions allow.
Cost magnitude?
CO delay on 200-unit apartment = $10-15k/day in lost rent + $5-10k/day carry. 30-day delay = $450-750k cost. Most expensive phase of construction to miss.
Who owns this risk — sponsor or lender?
Construction risks are typically shared: hard-cost overrun owned by sponsor (via completion guaranty), soft-cost and delay risks shared per contract, force-majeure excused but bears owner carry cost. Document risk ownership in the loan agreement and GC contract before closing. Disputes get expensive when roles are unclear. Institutional deals spell out every allocation in writing.
