Medical Office Development in Gilbert, AZ Poised for Growth

Medical office development in Gilbert is entering its strongest window in a decade. The town has grown to roughly 287,000 residents, household incomes sit well above the state average, and the healthcare corridor around Dignity Health Mercy Gilbert Medical Center is drawing new providers, new buildings and record-setting sales.

The tension is simple: patient demand has outrun specialty supply. ICRE’s analysis of the 1, 3 and 5-mile trade area around the hospital shows a large, affluent, fast-aging population that still has to drive across the Valley for rheumatology, allergy, neurology and several other specialties. That gap is exactly what the next physician group or health system can fill.

Five things every physician group, health system and medical office investor should know about this corridor:

The population is big and still growing. About 305,000 people live within 5 miles of Mercy Gilbert, up 43% since 2010, with roughly 15,000 more expected by 2031.
The spending is premium. Households within 5 miles spend about $1.13 billion a year on healthcare, 39% above the U.S. average.
The payer mix is commercial. About 71% of residents carry employer or individual coverage; only about 6% are uninsured.
Key specialties are missing. Rheumatology, allergy/immunology and neurology each have just one to three practices serving the entire 5-mile area.
Capital is already moving in. A medical office property on S. Val Vista Drive traded for $51.5 million in Q2 2026, and 46 healthcare permits have been filed within 5 miles since September 2024.

Below, we break down the market data, the risks and the specific opportunity at ICRE’s two ground-up medical developments next to Mercy Gilbert.

Current Market Context

Metro Phoenix medical office fundamentals are firming. Kidder Mathews reports Phoenix medical office direct vacancy fell to 15.1% in Q2 2026, down from 15.8% in Q1, while average asking rents rose to $34.39 per square foot full service. Net absorption turned positive at 60,076 square feet, and no new medical office buildings delivered during the quarter.

Investors noticed, and medical office development in Gilbert is where much of the capital landed. Metro medical office sales volume climbed to $151.8 million in Q2 2026, up from $88.9 million in Q1, and the single largest trade of the quarter was in Gilbert: 3530 S. Val Vista Drive sold for $51.5 million, about a third of the quarter’s total volume. That property sits a short walk from Mercy Gilbert.

Locally, the hospital itself anchors the demand. Mercy Gilbert opened in 2006 with 88 beds and now operates as a 197-bed, full-service hospital. It is also home to the Women’s and Children’s Pavilion developed with Phoenix Children’s, a project that has pulled pediatric specialty clinics onto S. Mercy Road.

Why Medical Office Development in Gilbert, AZ Is Poised for Growth Near Mercy Gilbert

Medical office development in Gilbert works when three things line up: people who need care, payers who can support new-construction rents, and a shortage of the right providers. The Mercy Gilbert trade area has all three, and our data shows it more clearly than most submarkets in the Valley.

1. Demographics that drive visits

Using Esri Business Analyst data, ICRE measured 1, 3 and 5-mile rings around the hospital. The 5-mile ring holds 305,194 residents today and is forecast to reach nearly 320,000 by 2031. Median household income is $140,794, and it climbs to $148,715 within 3 miles.

The fastest-growing group is the one that uses the most care. Residents 65 and older are projected to grow 18%, from 36,354 to 42,948, by 2031, and those 75 and older grow about 21%. At the same time, adults aged 25 to 34 grow about 25%, a family-formation wave that feeds OB-GYN, pediatrics and fertility demand.

2. Payers that support new construction

Rent on ground-up space only pencils when tenants have strong reimbursement. Within 5 miles, about 71% of residents carry commercial coverage, roughly 10% are Medicare-primary (many with Medigap or retiree plans on top), 5.5% rely on Medicaid (AHCCCS) only, and about 6% are uninsured. Household spending on physician services runs 48% above the national average, and hospital services run 53% above.

3. Specialty gaps that are hard to ignore

Comparing demand with provider locations tells the real story. General dentistry (163 locations), physical therapy (70) and orthopedics (52) are crowded. But the specialties that an aging, affluent population needs most are thin:

Rheumatology: one practice for roughly 305,000 residents.
Allergy and immunology: two locations, even though allergist visits run 16% above the national rate.
Neurology: two to three practices as the 75-plus population grows 21%.
Endocrinology, ENT, audiology and surgical eye care: four or fewer providers each, with no stand-alone audiology center identified.

For a physician group, that is a built-in referral base with little local competition. For a health system, it is an obvious place to plant a specialty center that keeps patients in-network.

Local Arizona Impact: Gilbert’s Growth Story

Gilbert has been one of Arizona’s most consistent growth engines. The U.S. Census Bureau estimates Gilbert’s population at 287,285 as of July 2025, up 7.2% since 2020, with a median household income of $122,551. The Town’s economic development office projects that Gilbert will be essentially built out by 2030 at more than 330,000 residents.

That build-out matters for medical office development in Gilbert. As the town runs out of land, well-located medical parcels near a hospital become scarcer and more valuable. Buyers who secure a hospital-adjacent site now will be positioned to capture that demand before the land is gone.

Permit data confirms the momentum. ICRE reviewed municipal records for Gilbert, Chandler and Mesa and found 46 healthcare-related building permits within 5 miles of Mercy Gilbert since September 2024, including 17 within one mile. Projects include a new three-story, 67,946-square-foot medical office building on the hospital campus, a 7,800-square-foot orthopedic clinic expansion with 16 exam rooms, dental and orthodontic build-outs, a birth center, and pharmacy build-outs. Nearby in Chandler and Mesa, a community health center expansion and a 20-bed rehabilitation hospital addition are also in the pipeline.

Active Medical Permits Near Mercy Gilbert

Seven healthcare permits within 5 miles are currently marked active in municipal records. Here is what each one tells us:

Brikhouse Orthodontics, 3635 S. Val Vista Dr. (0.2 mi): signage for a new orthodontic office in a 2023 building across from the hospital that also added a dental office, a birth center and a light-therapy suite. A new building next to the hospital filled with healthcare users shows how strongly providers want hospital-adjacent space.
Val Vista Pharmacy, 3570 S. Val Vista Dr. (0.2 mi): a $59,800 build-out for an independent pharmacy. Pharmacies follow prescription volume, and prescription spending within 5 miles runs 30% above the U.S. average.
Medical office remodel, 3345 S. Val Vista Dr. (0.3 mi): a $108,390 remodel of an existing medical office for a new tenant. The building then sold for $23.0 million in August 2025, proof that investors pay a premium for re-tenanted medical space near the hospital.
Dental suite, 3200 S. Gilbert Rd., Chandler (2.8 mi): fire-sprinkler work for a new dental office. Dental keeps growing, but it is already the most crowded category, with about 163 offices within 5 miles.
Premier Family Dental Care, 3050 E. Chandler Heights Rd. (4.0 mi): a $154,400 expansion of an existing practice. Practices only expand when patient volume outgrows their space, which is a sign of healthy demand in south Gilbert.
Elite Dental Wellness, 5221 S. Power Rd., Mesa (4.5 mi; two permits): a new 3,471-square-foot dental office worth $280,000 plus signage. Providers are following new rooftops east toward Power Road and the Gateway area.

The bigger pipeline is still in review, led by the 67,946-square-foot medical office building on the hospital campus, the Ortho AZ clinic and a hospital-affiliated weight-loss center. Together, the permits point to three conclusions. First, the corridor within one mile of Mercy Gilbert is the hot spot, with 17 of the 46 permits. Second, existing practices are expanding, which reflects real patient demand rather than speculation. Third, almost all of the activity is dental, orthopedic, pharmacy and general clinic space. None of it is for rheumatology, allergy, neurology, endocrinology or audiology, the specialties this market is still missing.

The takeaway for the East Valley: Gilbert, Chandler, Mesa and Queen Creek are competing for the same wave of outpatient investment, and the Mercy Gilbert corridor has the strongest combination of hospital adjacency and household wealth.

National Impact

Nationally, medical office is one of the most resilient property types. MMCG, citing CBRE, reports U.S. medical office vacancy at 9.8% versus roughly 19% to 21% for traditional office, with construction running near 2% of total stock. New buildings command about a 33% rent premium over existing space, because replacement costs now run $400 to $560 per square foot.

Two long-term forces keep demand rising. First, aging: Americans 65 and older generate about three times as many physician visits per person as adults 18 to 44. Second, the shift to outpatient care: hospital outpatient revenue grew from 52% to 57% of total hospital revenue between 2020 and 2024, and adult outpatient volumes are forecast to grow 18% over the decade. Both trends land directly on off-campus and hospital-adjacent medical office.

Key Risks

New competing supply. The 67,946-square-foot building on the Mercy Gilbert campus will be leasing in the same window, so undifferentiated “general medical office” space faces a rent fight.
Construction and interest costs. Higher rates and replacement costs raise the rent a ground-up project needs; pre-leasing before delivery is essential.
Saturated categories. Dentistry, orthodontics, physical therapy and urgent care are crowded; chasing them compresses rents and lengthens lease-up.
Reimbursement changes. Medicare physician-fee pressure can slow smaller independent groups, which favors health-system and specialty-platform tenants.

Key Opportunities

Specialty centers for health systems. A 10,000 to 20,000-square-foot multi-specialty or pediatric specialty center next to the hospital keeps referrals in-network.
Chronic and aging-care clusters. Rheumatology with infusion, neurology and endocrinology share patients and referral sources and fit 2,000 to 4,000-square-foot suites.
Allergy, ENT and audiology suites. A combined suite serves a family-heavy population with desert allergy demand and hearing-aid spending 32% above average.
Surgery, imaging and eye care. Surgical eye care, endoscopy and freestanding imaging benefit from the shift to outpatient procedures and a commercially insured base.
Patient and family lodging. Hotel pads beside a women’s and children’s hospital campus serve families traveling for pediatric and maternity care.

The ICRE Perspective

In the field, we are seeing physician groups tour Gilbert space and hesitate because most available suites were built for dental and general practice. What they want, and what is scarce, is purpose-built space next to the hospital that can take infusion rooms, procedure rooms or imaging, delivered on a clear schedule.

That is why ICRE is marketing two ground-up opportunities that answer the need for purpose-built medical office development in Gilbert, both next to Mercy Gilbert:

Mercy Vista Medical: five separately parceled PAD sites next to Mercy Gilbert, each with its own APN. PADs 2 and 3 are poised for medical, and PADs 4 and 5 suit medical or hotel use, all available to owner-users. Download the brochure or contact our team for site plans and pricing.
East Valley Healthcare Anchor: multiple adjacent parcels suited for a medical campus, build-to-suit or owner-user headquarters for a health system or large specialty platform, with layouts and development scenarios available in the offering materials.

What investors are missing is that the value here is not “more medical office.” It is the right medical office. A project leased to under-supplied specialties with hospital referral ties will hold occupancy and value far better than one competing with the next dental suite down the street. The risk being underestimated is timing: the groups that commit now will lock in the best positions before campus supply catches up.

Tenant and Investor Takeaways

Demand is proven. 305,000 residents, $1.13 billion in annual healthcare spending and a 71% commercial payer mix support new-construction rents.
Target the gaps. Rheumatology, allergy/immunology, neurology, endocrinology, audiology and surgical eye care are the clearest openings.
Proximity is the premium. The largest Phoenix medical office sale of Q2 2026 was a short walk from Mercy Gilbert.
Move before build-out. Gilbert is expected to be nearly built out by 2030, so hospital-adjacent land will only get scarcer.
Pre-lease to specialists. Anchor ground-up projects with specialty or health-system tenants to stand apart from nearby general medical space.

Conclusion

The strategic takeaway is clear: medical office development in Gilbert near Mercy Gilbert Medical Center offers a rare mix of growth, wealth, strong payers and real specialty gaps. It is not a speculative bet on population; the patients, the spending and the hospital are already there.

Looking ahead, the senior population will keep climbing through 2031, outpatient care will keep shifting off the hospital floor, and Gilbert’s remaining land will keep shrinking. That combination points to rising rents and values for well-located, purpose-built medical space over the next five years.
