Frequently Asked Questions
What delays CO?
Punch-list completion. Fire marshal inspection. Elevator certification. Accessibility compliance. Health department (for restaurants). Landscaping (Virginia/Florida requirements). Misaligned inspection schedules. Each agency often requires separate appointments.
Typical CO timing?
Permit-ready multifamily: 30-60 days post-substantial completion. Complex commercial: 60-120 days. Mixed-use: 90-150 days. Historic: 120-240 days (multi-agency). Pandemic-era: add 30-60 days for agency backlogs.
Reducing delay?
Pre-coordinate with inspectors during construction. Dedicated expediter/permit runner. Complete accessibility review in design. Deliver punch-list fast. Schedule inspections early. Multiple certificates (Temporary CO, Partial CO) to occupy in phases while pursuing full CO.
How often should I rerun this?
Rerun this calculator whenever inputs change materially — new rent roll data, rate moves, loan balance updates, or quarterly operating data. For active deals, monthly refresh is typical. For stabilized assets under monitoring, quarterly is fine. Treat the output as a decision tool, not a one-time answer — market conditions evolve and so should your analysis.
