Planning a Pharmacy Buildout in Houston
Independent pharmacies, clinic pharmacies, specialty pharmacies and compounding pharmacies all open in Houston strip centers, medical office buildings and freestanding buildings. From the parking lot, a pharmacy can look like any other retail suite. Behind the counter, it is a controlled space with security, storage, workflow and sometimes clean-room requirements that a typical retail buildout never has to think about.
Owners and landlords who plan a pharmacy like an ordinary retail space often run into problems late in the project: the drop ceiling doesn't support the security design, the compounding room can't hold the right air pressure, the plumbing is in the wrong place, or the board inspection turns up layout issues that should have been caught on paper. This guide walks through what to plan before construction begins.
This page is general information, not legal, pharmacy or design advice. Work with your pharmacist-in-charge, an architect, engineers, your attorney and the regulators who oversee your pharmacy type.
Know which regulators are involved
A pharmacy buildout answers to more than the city building department. The Texas State Board of Pharmacy sets rules for pharmacy classes, including space, security and equipment expectations, and may inspect before the pharmacy opens. Pharmacies that handle controlled substances also deal with the DEA Diversion Control Division, which has its own security expectations. Inside city limits, building permits run through the Houston Permitting Center.
Ask your pharmacist-in-charge or consultant which rules apply to your pharmacy class before the architect finalizes the layout. It is far easier to change a drawing than a finished wall.
Choosing the right space
Before you sign a lease or buy a building, look at:
- Visibility and access: Customers, drivers and delivery services need a clear path to the counter and, if planned, a drive-thru lane.
- Drive-thru feasibility: Stacking room, traffic flow and the landlord's site plan all affect whether a drive-thru window is possible.
- Ceiling and structure: Security walls, cameras and equipment need solid support. A structural review may be needed for heavy shelving or safes.
- Utilities: Confirm water, drain, electrical capacity and data service before committing.
- Deed restrictions and lease use clauses: Some centers limit pharmacy use or have exclusives held by another tenant. The City of Houston Legal Department's deed restriction resources are a starting point, and your attorney should review the lease and any recorded restrictions.
Security planning
Security drives much of the pharmacy layout:
- Pharmacy department walls: Many pharmacies need walls that run to the deck, not just to the drop ceiling, so no one can climb over.
- Doors and hardware: Solid doors, controlled locks and limited access points.
- Cameras and alarms: Coverage of the counter, storage, entries and any drive-thru.
- Safes and secure storage: Controlled substances storage needs a planned location, anchoring and access.
- After-hours separation: If the pharmacy sits inside a larger store or clinic, the pharmacy area may need to lock separately.
CISA's physical security resources offer general guidance, and your security vendor and regulators will define specifics.
Workflow and layout
A pharmacy layout should follow how prescriptions move:
- Drop-off and intake
- Data entry and verification
- Filling and counting stations
- Pharmacist check
- Storage and will-call
- Pick-up and counseling
Each step needs counter space, power, data and good lighting. A private counseling area or consult room is common. Will-call storage often grows faster than owners expect, so plan room for it.
Compounding rooms
Compounding pharmacies have the most complex buildouts. Sterile compounding may need a clean-room suite with an anteroom, a buffer room, pressure control, specialized air filtration, smooth cleanable surfaces and sealed ceilings. Hazardous drug compounding may need negative pressure and separate exhaust.
These rooms involve mechanical engineering, certification testing and careful construction sequencing. Talk with your pharmacist-in-charge, a mechanical engineer and a certification firm before the design is set. Our guide to laboratory buildout planning covers many of the same air and finish questions.
Plumbing and sinks
Pharmacies typically need hand sinks and prep sinks in specific locations. Compounding areas may need sinks placed outside the clean rooms. Slab cuts for new drains in an existing suite add time and should be planned early. Our guide to second-generation space explains what can and can't be reused from a prior tenant.
Electrical, data and refrigeration
- Refrigerators and freezers: Vaccine and medication storage needs dedicated circuits and often backup power or temperature alarms.
- Workstations and printers: Many outlets and data drops at counter height.
- Automation: Counting machines and dispensing robots need power, data and floor space.
- Backup power: Consider whether the pharmacy needs a generator connection for refrigeration. Our guide to commercial standby generator planning explains the basics.

HVAC and temperature control
Medications have storage temperature limits, and Houston summers are hard on HVAC. Plan for reliable cooling, good humidity control and temperature monitoring in storage areas. Compounding rooms need their own air design. If the suite's rooftop unit is old, review it before opening. Our guide to commercial rooftop HVAC replacement can help.
Accessibility
Customer areas, counters, the counseling room and restrooms must meet accessibility requirements. The 2010 ADA Standards set the federal baseline, and Texas projects may require registration and review through the TDLR Architectural Barriers program. Our guide to ADA items to review in a buildout explains common items.
Finishes
Pharmacy finishes should be durable and easy to clean:
- Sealed, cleanable flooring in work areas
- Solid-surface or laminate counters that resist chemicals
- Smooth, cleanable walls and ceilings in compounding areas
- Good, even lighting for accurate filling and checking
Permits and inspections
Most pharmacy buildouts need building, electrical, plumbing and mechanical permits, plus fire marshal review where required. The Houston Fire Marshal's Office may review the plans. A certificate of occupancy is usually needed before opening. Our guides to the buildout permit process in Houston and the certificate of occupancy for a lease space explain the steps.
Board and federal inspections often happen after construction, so the space must match what was approved on paper.
Lease questions
- Who pays for security walls, the safe and compounding rooms?
- Is a drive-thru allowed in the site plan?
- What happens to clean-room improvements when the lease ends?
- Are there exclusives or use limits in the center?
- Who maintains the HVAC serving the suite?
Our guide to landlord work vs tenant work letters explains how responsibilities are usually divided. Your attorney should review the final lease.
