What’s a realistic timeline for medical office building construction?
For a typical 50,000–100,000 square-foot medical office building (MOB), plan for 18–30 months from initial concept to opening, with the biggest variables being delivery method, Authority Having Jurisdiction (AHJ) reviews, and specialty scope such as imaging or an ambulatory surgery center (ASC). Why it matters Time drives return on invested capital. At a 5% cost of capital, each month of delay on a $50 million project translates to roughly $208,000 in carrying cost before a single patient is seen—capital that could otherwise support clinical growth or workforce initiatives. In today’s environment of higher borrowing costs and competitive ambulatory expansion, compressing the schedule without compromising quality directly improves ROI and speeds access to care. Market dynamics also favor timely delivery. In fast-growing regions such as Nashville and Middle Tennessee, physician alignment, outpatient market share, and site control move quickly; a slow real estate timeline can force program compromises or lost opportunities. The goal is realism—anchoring milestones to evidence-based benchmarks—so executives can align clinical, capital, and operational decisions with confidence. How it works The end-to-end MOB timeline typically includes: strategic alignment and programming; site [...]
