Medical Office Space: How to Find and Lease Your First Clinical Location
Medical office space has unique physical requirements that standard commercial space doesn't meet — plumbing for hand-washing sinks in every exam room, ADA-compliant layouts, electrical capacity for diagnostic equipment, and sound attenuation between exam rooms for patient privacy. Signing the wrong lease is a six-figure mistake that's very hard to undo. This guide walks through finding the right location, understanding medical office building (MOB) market dynamics, and the critical lease provisions every physician should negotiate before signing.

The Quick Answer
Start your search on LoopNet.com using the 'Medical / Dental / Veterinarian' property use filter to find spaces already built out for clinical use. Second-generation medical space (a previous doctor's office) saves $30,000–$100,000 in build-out costs versus raw commercial space. Target Medical Office Buildings (MOBs) near hospitals for specialist referral traffic, or neighborhood retail corridors for primary care and DPC. Budget $25–$45/SF annually for MOB space in most markets ($35–$65/SF in major metros). Negotiate tenant improvement (TI) allowances of $40–$80/SF from landlords in 2026's office market — vacancy rates are high and landlords are motivated to offer concessions.
Medical Office Buildings vs. Retail/Flex Space
Medical Office Buildings (MOBs) are designed specifically for clinical use — they have reinforced floors for heavy equipment, higher electrical capacity, HVAC zoning for infection control, and multiple hand-washing sinks per suite. Hospital-affiliated MOBs (on or adjacent to hospital campuses) provide built-in referral relationships and patient traffic but charge premium rents ($40–$65/SF/year) and often have restrictive lease covenants. Independent MOBs typically run $28–$45/SF/year and offer more flexibility. Retail medical space (strip malls, end-cap locations) is increasingly viable for primary care, urgent care, and DPC practices — visibility, parking, and accessibility often surpass MOB locations, and rents can be 20–40% lower. For specialists, being on or near a hospital campus often matters more than for primary care physicians.
ADA and Physical Requirements for Exam Rooms
The Americans with Disabilities Act sets specific requirements for medical offices. Exam rooms must be at least 80 square feet (larger for specialty procedures). Doorways must be at least 32 inches clear width (36 inches preferred for wheelchair access). At least one restroom must be ADA-compliant with grab bars, appropriate clearance, and an accessible sink. Every exam room requires a hand-washing sink with wrist or elbow operation — this is both ADA and OSHA infection control compliance. Hallways must be at least 44 inches wide. Parking must include accessible spaces (1 per 25 spaces minimum). Confirm that any space you're considering meets these requirements — or budget for the modifications. A tenant improvement allowance from the landlord can fund ADA compliance work. Non-compliance exposes you to HHS civil rights complaints and ADA lawsuits.
Plumbing, Electrical, and HVAC Requirements
Medical suites require more MEP (mechanical, electrical, plumbing) infrastructure than standard commercial space. Plumbing: a hand-washing sink in every exam room (not just a shared sink in the hallway) requires individual plumbing drops — confirm these exist before signing. Each sink needs both hot and cold water with a mixing valve for OSHA-compliant hand hygiene. Electrical: clinical equipment draws significantly more power than standard office use; confirm the space has adequate panel capacity (ideally 200-amp service minimum for a 3-exam-room practice). HVAC: ensure the system can maintain positive/negative pressure differentials between procedure rooms and waiting areas if you perform any aerosolizing procedures. Ask the landlord for a current MEP drawing of the space and have a contractor review before signing. Plumbing add-ons in leased space can cost $5,000–$25,000 per sink location — major expenses that should be covered by TI allowances.
Lease Negotiation: Critical Provisions for Physicians
Never sign a medical office lease without a healthcare real estate attorney reviewing it — physician leases have provisions that don't exist in standard commercial leases. Key negotiating points: (1) Tenant Improvement Allowance: push for $40–$80/SF — in 2026's soft office market, many landlords offer $50–$100/SF TI for medical tenants willing to sign 5–7 year leases. (2) Exclusive use clause: prevents the landlord from leasing adjacent space to a competing specialty. (3) Personal guarantee limitation: physicians often face personal guarantee requirements on practice leases — negotiate for a 'burndown' guarantee that reduces as you demonstrate revenue. (4) Assignment rights: if you sell the practice, you need lease assignment rights without landlord approval or with reasonable approval standards. (5) Co-tenancy clauses: for hospital-adjacent MOBs, include a clause reducing rent if the anchor hospital relocates. (6) Termination clause: negotiate a physician death/disability termination right.
Finding Space: LoopNet, Healthcare REITs, and Tenant Reps
LoopNet (loopnet.com) is the standard commercial real estate listing platform — filter by 'Medical / Dental' property type and target second-generation space. CoStar (the institutional platform behind LoopNet) has more complete data but requires a subscription ($500+/month). Crexi (crexi.com) is a newer competing platform with strong medical listings in many markets. Healthcare-specific REITs (Healthcare Trust, Physicians Realty Trust — now merged with Healthpeak) own large MOB portfolios and often advertise directly — contact their leasing teams. Most importantly, engage a tenant representative commercial real estate broker who specializes in medical office — they're paid by the landlord (no cost to you), know which landlords are offering the best TI packages, and understand medical lease provisions. Ask physicians in your area who they used for their lease — personal referrals to experienced medical tenant reps are the best sourcing method.

FREQUENTLY ASKED QUESTIONS
How much square footage does a solo physician practice need?
A solo physician with 2 exam rooms needs a minimum of 800–1,200 SF. A 3-exam-room solo practice with a dedicated waiting room and private office runs 1,400–1,800 SF. Group practices with 2+ physicians need 2,500–4,000 SF. DPC practices can operate in as little as 600–800 SF if appointment density is low — some DPC physicians launch in shared medical suites at $800–$2,000/month without a long-term lease commitment.
What is a tenant improvement allowance and how do I negotiate one?
A Tenant Improvement (TI) allowance is a landlord contribution toward the cost of building out your space. In 2026's office market with elevated commercial vacancy rates, TI allowances of $40–$80/SF are achievable for medical tenants signing 5–7 year leases. On a 1,500 SF suite, $60/SF TI equals $90,000 toward build-out — which can cover most or all of a basic medical suite renovation. To maximize TI: provide detailed build-out plans and contractor bids to the landlord before negotiating, get competitive offers from multiple properties, and be willing to sign a slightly longer lease term in exchange for a larger allowance.
Can I rent shared medical office space instead of signing a full lease?
Yes — shared medical office space or medical co-working spaces are viable for DPC, telehealth-heavy, and part-time practices. Platforms like Sked, Emerge, and local medical co-working spaces rent exam rooms by the hour or day ($30–$100/hour). This eliminates lease risk entirely during the first 6–12 months while you build your patient panel. Once you reach 200+ patients (DPC) or $20,000+/month in collections (insurance-based), transitioning to a dedicated lease typically makes more financial sense.
