9 Lease Questions to Ask Before Your Dental or Medical Office Build-Out in South Florida
Planning a dental office build-out in South Florida? The most expensive problems in a healthcare space are usually decided before construction starts, in the lease. A unit with the sewer line on the wrong side of the slab, a small electrical service, or a work letter that puts most of the cost on the tenant can change your budget before the first wall goes up.
These are the questions we ask when we walk a space with dentists and physicians in Doral, Miami, Coral Gables, Fort Lauderdale, Boca Raton, West Palm Beach and across South & Central Florida.
This article is general information, not legal or engineering advice. Have a real estate attorney review your lease, and have licensed design professionals review the space, before you sign. A preliminary site walkthrough is not a substitute for a formal engineering evaluation.
1. Is the space zoned for a medical or dental office?
Allowed uses are set by the city or county, and they vary by zoning district. Moving from retail or general office to a medical use may trigger extra review, parking requirements or building upgrades. Ask the landlord in writing whether a healthcare use is permitted, and confirm with the zoning office for that city or county before you commit.
2. Where are the plumbing and sewer lines?
A dental office needs water and drains at or near most operatories, plus sterilization, a lab area and drainage for equipment. Depending on the practice, medical offices may require exam-room sinks and other plumbing fixtures, plus accessible restrooms. On a site walk, we look for cleanouts, floor drains and existing restrooms to estimate where the sewer runs. If it’s far from your operatories, the slab may need to be cut and trenched, which adds cost and time. Ask the landlord for the base building plans.
3. Can the electrical service handle your equipment?
Chairs, X-ray and CBCT units, sterilizers, compressors, vacuum pumps and HVAC all add load. We review the electrical panel labeling and available service information. Panel labels alone don’t establish available capacity; that takes further evaluation. Some older shells may need an upgrade that depends on the utility’s schedule. Ask what service the unit has, whether the landlord will pay for an upgrade, and whether the meter is shared.
4. Is there room for medical gas, vacuum and air equipment?
If you plan to use nitrous oxide, oxygen or medical vacuum, NFPA 99 and the applicable Florida codes apply based on the specific system and installation, so requirements are not the same for every office, and the work is done by qualified installers. Make sure the lease lets you place the compressor and vacuum pump where they can be vented and serviced, run lines through ceilings and walls, and store cylinders in an approved location.
5. Will X-ray or imaging rooms need shielding?
In Florida, X-ray equipment generally must be registered with the Florida Department of Health. Shielding is a separate question: whether a shielding evaluation is needed, and what it calls for, depends on the equipment and installation, and it is confirmed by a qualified expert. Whether you need lead in the walls, doors or floor depends on the equipment and what’s next door, above and below. Tell the landlord early that you plan imaging, and make sure the lease allows the wall and door work that may be needed.
6. What’s in the landlord’s work letter?
The work letter, or tenant improvement exhibit, sets out what the landlord delivers and what you pay for. Read it line by line and look for:
- The tenant improvement allowance, and when and how it’s paid
- Delivery condition: cold dark shell, warm shell or second-generation space
- Who pays for HVAC, electrical service, restrooms and fire sprinkler changes
- Whether you must use the landlord’s contractor or approved vendors
7. How long do landlord approvals take?
Most landlords review your plans before they go to the building department, and some have their own engineer review them too. Turnaround varies widely. Ask for the process and expected timing in writing so you can plan around it. Whether landlord approval is required before permit submission depends on your lease.
8. When does rent start?
Free rent periods often start on a fixed date, not when you open. Permit review and inspection timing vary by jurisdiction and workload, so a calendar date can arrive before the work is done. Certificate of occupancy and opening are different milestones, and a certificate of occupancy can come well before you’re ready to see patients. Ask whether rent can start at one of those milestones instead of a fixed date. Commencement provisions are often negotiated, though landlords may or may not agree, so raise them before you sign.
9. What happens when the lease ends?
Some leases require you to remove your improvements and restore the space. For a healthcare office, that can mean removing plumbing, gas piping and shielding. Ask whether restoration is required, and try to remove or limit it. Leave the legal interpretation and negotiation of these terms to your attorney.
