Here's what happens: a commercial real estate buyer spends months on financials, title, environmental, and roof conditions. The elevator gets one line in the Phase I report -- "elevator equipment observed, recommend review of maintenance records." Then the deal closes. Six months later, a $45,000 hydraulic cylinder replacement bill lands on the new owner's desk. Or the state inspector shows up day one and shuts the unit down because the Certificate of Operation lapsed.
Both situations happen constantly. A buyer who brings in an elevator industry professional for a pre-purchase evaluation almost never gets surprised.

Why Elevators Get Missed
Most CRE (Commercial Real Estate) due diligence leans on environmental, structural, and financial review. Elevators fall into the MEP (Mechanical, Electrical, Plumbing) bucket, which means a mechanical engineer confirms the units run during a 30-minute site walk.
Operational is not code-compliant. And code-compliant is not capital-safe over the next 5-10 years.
An elevator that runs fine today can still represent $30,000-$150,000 in near-term capital exposure if the modernization clock is ticking, the hydraulic cylinder is a pre-mandate single-bottom unit, or the Certificate of Operation has lapsed without disclosure.

The Checklist
Work through these for every elevator in the building before close. If the seller cannot produce documentation for any item, treat it as a red flag and price accordingly.
1. Certificate of Operation
Request copies for each unit. Confirm it is valid, posted in the cab, and that the most recent state inspection had no unresolved violations. A lapsed certificate means the state can order immediate shutdown -- your tenants lose elevator access on day one of ownership. There is no grace period for new owners.
2. Equipment Age and Type
Confirm installation date (nameplate in machine room or cab). Identify drive type: hydraulic, traction (geared or gearless), or MRL (Machine Room-Less). For hydraulic units, identify cylinder type -- single-bottom in-ground vs. holeless vs. above-ground. For traction, check rope material and last replacement date.
A 1985-vintage hydraulic elevator with a single-bottom in-ground cylinder is a significant liability. The ASME (American Society of Mechanical Engineers) A17.1-2013 standard requires replacement of unlined single-bottom cylinders, and most states have adopted it. Cost: $15,000-$60,000 depending on depth and site conditions.
3. Maintenance Records
Request service logs for the last 3 years minimum. Confirm preventive maintenance visits match the contract schedule. Review repair history -- what systems were replaced, what was deferred, and what keeps breaking. Recurring repairs on the same component mean an underlying problem the seller has been patching instead of fixing.
A well-maintained elevator shows consistent visit records and a repair trend that improves over time. A neglected one shows spotty visits, repairs clustered before inspections, and the same items flagged repeatedly.
4. Service Contract Terms
Get a copy of the current contract. Confirm the type: Oil & Grease (O&G) covers lubrication and adjustment only -- major components are extra. Full Maintenance (FM) covers most parts and labor. Know the difference before close. Also confirm: expiration date, assignability to new owner, open work orders, and outstanding repair authorizations.
On older equipment, the gap between an O&G contract ($2,400-$4,000/yr) and an FM contract ($6,000-$12,000/yr) can be less than one major repair event.
5. Modernization History
Confirm whether any modernization -- a full rip-out and replace of the controller, door operator, fixtures, and wiring -- has been done in the past 10 years. Ask when the service company last quoted modernization and for which components. Check if the state has issued any compliance orders requiring code updates.
Commercial elevators typically face a full modernization every 20-30 years. A 1998 installation is approaching or past that window. Even a partial upgrade (controller, door operators, cab interior) runs $25,000-$80,000. A full drive-system modernization can reach $150,000-$250,000. If the equipment is aging and nothing has been done, that capital cost is coming -- the only question is whether it lands on the seller or you.
6. Emergency Phone and ADA Compliance
Confirm the two-way emergency phone works and connects to a 24/7 monitoring center. This phone is critical during elevator entrapments and must function reliably. Check cab interior for Americans with Disabilities Act (ADA) compliance: button height, Braille labels, audible indicators.
Red Flags That Should Affect Price
In order of severity:
- Lapsed or missing Certificate of Operation -- immediate legal exposure, unit cannot operate until resolved
- Single-bottom hydraulic cylinder with no replacement documented -- $15K-$60K liability
- Maintenance logs with 6+ month gaps -- equipment running unserviced, condition unknown
- Multiple deferred work orders -- seller declining repairs, hiding condition
- Service company cannot produce a clean bill of health in writing -- they know something
How to Use This
Take this list to your general contractor or MEP engineer and ask them to cover it in the Phase I assessment. Most will not have the elevator-specific knowledge to evaluate cylinder type or code compliance exposure. The better option: bring in an elevator industry professional for a dedicated pre-purchase assessment. That is a 2-4 hour engagement covering everything on this checklist plus a physical inspection of the pit, machine room, and cab. For a building with 1-3 elevators, expect $200-$500 -- worth multiples of that in avoided surprises.
Due diligence should include understanding modernization costs - it's where the biggest capital surprises come from.
Scan the Seller's Service Contract Before You Close
One of the six items above is the service contract, and it hides the most easily missed liabilities: an O&G agreement masquerading as full coverage, an auto-renewing evergreen clause, or open repair authorizations you inherit at closing. Run the seller's agreement through the Contract Scanner during your due-diligence window. In under five minutes it flags the contract type, escalation clauses, assignability, and exclusions, so a $50K surprise does not land six months after the keys change hands.

Frequently Asked Questions
What are the 6 critical elevator items CRE buyers should check before closing?
The 6 critical items are: 1) Certificate of Operation status (confirm valid and no open violations; lapsed certificate means same-day shutdown risk), 2) Equipment age and type (check installation date and identify cylinder type on hydraulic units; single-bottom unlined cylinders are $15K-$60K liabilities), 3) Maintenance records (request 3 years minimum; gaps of 6+ months indicate neglect), 4) Service contract terms (confirm O&G vs FM, expiration date, assignability, and open work orders), 5) Modernization history (check if equipment has been updated in past 10 years; 20-30 year old systems need $25K-$250K modernizations), and 6) Emergency phone and ADA compliance (confirm two-way phone connects to monitoring center and cab meets ADA button height, Braille, and audible indicator requirements). These items catch the $50K+ surprises that standard Phase I reports miss.
What is the biggest elevator risk when buying a commercial building?
The biggest risk is a lapsed or missing Certificate of Operation. The certificate runs with the equipment, not the owner, so you inherit the exact compliance status at closing. A lapsed certificate means the state can issue a same-day shutdown order with no grace period for new owners. This causes immediate ADA exposure, tenant disruption, and potential lease default risk. The path back takes 3-6 weeks minimum if starting cold, with costs ranging from $350 for an overdue annual inspection to $80K-$100K if single-bottom cylinder replacement is required. Standard property inspections do not catch this. A current-looking certificate does not mean compliant equipment. Check the state database yourself using the elevator's registration number before your contingency expires.
How much should a CRE buyer budget for elevator capital surprises after acquisition?
Capital surprises range from $15K to $250K depending on what was missed in due diligence. Common scenarios: Single-bottom hydraulic cylinder replacement (ASME A17.1-2013 mandate) costs $15K-$60K. Partial modernization (controller, door operators, cab interior) runs $25K-$80K. Full drive-system modernization reaches $150K-$250K on 20-30 year old equipment. An overdue Category 5 test costs $800-$2,500, but if the test reveals hydraulic issues triggering citations, remediation reaches $5K-$30K. Multiple accumulated violations can cost $5K-$30K+ to resolve over 8-20 weeks. Emergency mobilizations add 20-40% to these costs. The best approach: bring in an elevator industry professional for a 2-4 hour pre-purchase assessment ($200-$500 for 1-3 units). This investment catches issues that standard MEP engineers miss and prevents surprises that cost 100x more.
