Quick answer: A medical or dental office build-out in Los Angeles typically runs $120–$250 per square foot, higher than standard office TI due to medical gas lines, imaging-room shielding, and denser electrical and plumbing requirements. APLA Construction (CA Lic #1136359) handles this throughout Greater Los Angeles.
Medical and dental office build-outs carry requirements that don’t come up in a standard office or retail tenant improvement — medical gas lines, imaging-room shielding, infection control, and higher plumbing and electrical density all have to be planned before the walls close. APLA Construction (CA Lic #1136359) builds out medical and dental offices for small practices across Greater Los Angeles, coordinating the specialty trades this work requires alongside standard permitting.
What’s Different About a Medical or Dental Build-Out
- Medical gas and vacuum lines — oxygen, medical air, and vacuum for procedure rooms; nitrous oxide and vacuum lines for dental operatories, each requiring certified installation and testing
- Imaging room shielding — lead-lined walls, doors, and viewing windows for any room with X-ray, CT, or similar imaging equipment
- Specialized electrical — dedicated circuits and isolated ground for sensitive equipment, plus higher outlet density per exam or operatory room than a typical office
- Higher plumbing density — a sink in nearly every exam room or operatory, plus dental vacuum/suction lines, multiplies rough-in plumbing compared to a standard office TI
- HVAC and infection control — higher air-exchange rates in some clinical spaces, and an Infection Control Risk Assessment (ICRA) protocol during construction to contain dust and airborne particulates in an occupied medical building
- ADA exam room clearances — accessible exam tables, turning radius, and door clearances specific to clinical layouts, beyond standard ADA restroom/path-of-travel requirements
Permitting for Medical & Dental Offices in Los Angeles
Most private-practice medical and dental offices are outpatient clinical space and go through standard city permitting rather than the state-level hospital review process:
- LADBS (or local city) building permit — covers the construction, MEP, and structural scope, typically under a business/professional (B) occupancy classification
- Fire department review — occupant load, egress, and fire-rated separation for the clinical space
- ADA compliance — both standard path-of-travel requirements and clinical-specific clearances for exam rooms and equipment (see our ADA compliance guide for the path-of-travel rules that apply to any commercial remodel)
Practices affiliated with a hospital, or facility types licensed as general acute care or surgical centers, can trigger additional state-level review beyond standard local permitting — confirm your specific licensing category with your practice’s healthcare attorney or the California Department of Public Health before design begins, since it affects the permitting path from day one.
Medical & Dental Build-Out Costs in Los Angeles (2026)
| Item |
Typical Cost |
| Medical office TI (exam rooms, reception, basic plumbing) |
$120–$250 per sq ft |
| Dental office build-out (operatories, sterilization, vacuum system) |
$150–$300 per sq ft |
| Medical gas/vacuum system installation |
$15,000–$40,000 depending on room count |
| Imaging room lead shielding |
(walls, door, viewing window): $8,000–$20,000 per room |
| Specialized electrical |
(dedicated circuits, isolated ground): $10,000–$30,000 depending on equipment load |
These figures build on our general commercial tenant improvement cost guide — medical and dental space runs higher than standard office TI mainly because of plumbing density, medical gas, and equipment-specific electrical, not finish level.
Common Challenges on Medical & Dental Projects
- Equipment specs needed before rough-in — imaging equipment, dental chairs, and sterilization units all have specific plumbing, electrical, and sometimes structural requirements that need to be locked in before walls close, not after
- Long equipment lead times — specialized medical and dental equipment can take longer to arrive than standard construction materials, and scheduling needs to account for that separately
- Working in an occupied medical building — infection control protocols (dust containment, negative-pressure work zones) are often required when building near active clinical space
- Underestimating plumbing scope — a multi-operatory dental office or multi-exam-room medical suite has far more plumbing runs than a similarly-sized standard office
How APLA Handles Medical & Dental Build-Outs
- Equipment schedule review before permit drawings are finalized, so MEP rough-in matches your actual equipment, not a placeholder
- Coordination with medical gas and shielding specialty subcontractors as part of the overall project schedule
- Infection control planning when work is happening near or within an occupied medical building
- Permit drawings and LADBS submission sequenced with your practice’s opening or lease-commencement date in mind

Frequently Asked Questions — Medical & Dental Build-Outs in Los Angeles
Do medical and dental offices need a different permit than a standard office TI?
Most outpatient practices go through the same city building department as any commercial TI, but the scope reviewed includes medical gas, shielding, and clinical-specific electrical and plumbing that a standard office permit wouldn’t touch.
How much does it cost to add an X-ray or imaging room?
Beyond standard construction, budget $8,000–$20,000 for lead-lined walls, door, and viewing window, plus the electrical and structural requirements specific to the imaging equipment you’re installing.
Can I build out a dental office in a space that was previously a standard office?
Yes, but expect significant plumbing and electrical upgrades — most standard offices don’t have the vacuum lines, sink count, or dedicated circuits a dental operatory needs, so this is rarely a light retrofit.
Do I need ADA-compliant exam rooms in addition to standard ADA compliance?
Yes — clinical spaces have their own accessibility requirements for exam table clearances and turning radius, on top of the general path-of-travel and restroom requirements that apply to any commercial remodel.
How far in advance should I order medical or dental equipment relative to construction?
As early as possible — equipment specs drive your MEP rough-in, and long lead times on specialized equipment are one of the most common causes of schedule delays on these projects.
