East Valley medical office space has become one of the hardest commercial leases to sign in Arizona, and the reason has almost nothing to do with demand for healthcare. Demand is fine. Supply is the problem. Construction costs never came back down far enough to make new medical office buildings pencil, so developers largely stopped building them, and the buildings that already exist are now the entire market.
That produces a market that does not behave the way the headline numbers suggest. On paper, Phoenix medical office direct vacancy sits at 15.1%, which reads like a tenant’s market. In practice, try to lease 6,000 square feet of build-ready clinical space near a hospital campus in Gilbert or Mesa and you will find a short list, long lead times, and very little leverage.
Five things every healthcare tenant in this market should know before signing anything:
- Vacancy is falling, not rising. Direct vacancy dropped from 15.8% to 15.1% in the second quarter of 2026, and net absorption swung positive after a negative first quarter.
- Nothing new is being delivered. Phoenix recorded no new medical office deliveries in Q2 2026, and nationally new development sits at just 2.2% of existing inventory, down 10% year over year.
- Rents are moving up. Average direct asking rates rose to $34.39 per square foot full service from $33.80 — a premium of roughly $2 over general Phoenix office space.
- Buildout is your biggest number. Medical office improvements run $150 to $350 per square foot in hard costs against landlord allowances of $40 to $120. The gap comes out of your pocket.
- Start 12 to 18 months out. Between site selection, licensing, permitting, and a clinical buildout, the tenants who get the best space are the ones who started before they needed it.
This article breaks down what healthcare tenants are facing in Scottsdale, Gilbert, and Mesa, and how to compete for the space that is actually available.
Current Market Context
The national picture explains the local one. Medical outpatient buildings across the top 50 U.S. markets are now 92.5% occupied, with first-quarter absorption up 71% year over year. Investors have noticed: rolling four-quarter sales volume climbed 49% to $9.8 billion, with cap rates settling near 6.7%.
What makes this different from past cycles is the pipeline. Demand is demographic and essentially fixed: the 65-and-over population grows by nearly 11 million over the next decade, and spending on physician and clinical services is projected to rise 8.2% annually through 2033. Supply cannot respond, because the math on new construction still does not work.
Phoenix is following the same script with a lag. Absorption reversed to a positive 60,076 square feet after a negative first quarter, while quarterly medical office sales volume nearly doubled to $151.8 million. For tenants, the takeaway is simple: the window where East Valley medical office space was easy to negotiate is closing.
East Valley Medical Office Space: A Healthcare Tenant’s Guide to Scottsdale, Gilbert, and Mesa
The single most useful thing a healthcare tenant can understand about this market is why a 15.1% vacancy rate does not feel like 15.1% when you are actually touring buildings.
Most of that vacancy sits in older, non-clinical office product — second-generation suites with 9-foot ceilings, undersized electrical service, no plumbing stubbed to exam rooms, and parking ratios built for administrative tenants rather than patients. It counts as vacant medical office in the survey. It does not count as usable space for an imaging center or a surgical practice. Strip out the space that cannot realistically accommodate a clinical use, and the effective availability of true East Valley medical office space is a fraction of the reported number.
The second factor is where the vacancy sits. Health systems are pushing outpatient services away from central hospital campuses and into the suburbs where patients live, with Gilbert and Queen Creek among the fastest-growing target submarkets. Demand is concentrating in exactly the corridors with the least available inventory, while the softest space sits in locations tenants are actively leaving.
Third is the cost of making space work. Medical office buildouts run $150 to $350 per square foot in hard costs before soft costs add another 8% to 15% and contingency adds 5% to 10%. Landlord allowances cover a portion of that, not the whole thing. A cold dark shell can swing your total cost 30% to 50% versus a vanilla shell, which means the building that quotes the lowest rent is frequently the most expensive building to occupy.
This is why second-generation medical space — a suite already built out by a departing practice — rarely reaches the open market. When one becomes available, it is usually leased through relationships before a sign goes up.
Local Arizona Impact: Growth in Scottsdale, Gilbert, and Mesa
The East Valley is home to roughly 1.4 million residents and is projected to add another 400,000 by 2050. That growth is what health systems are underwriting, and their capital commitments are the clearest signal of where East Valley medical office space demand goes next.
Gilbert. Gilbert has just over 289,000 residents today and is projected to exceed 330,000 by 2030, with a median age of 36.1 — a young, family-heavy population that drives pediatrics, OB/GYN, orthopedics, and urgent care. The town is absorbing new clinical product as fast as it delivers: the 120,000-square-foot Melrose Professional Park and the 68,000-square-foot Celebration Medical Center are both Class A medical projects, and Banner Gateway is adding a patient tower. Gilbert also posted the Valley’s largest medical office trade last quarter at $51.5 million.
Mesa. Mesa is the volume market. With 523,220 residents in 2025 growing to a projected 538,738 by 2030 and a median household income of $83,458, it offers the deepest patient base and the most attainable rents of the three. Banner Desert Medical Center has expanded its women’s and infant services and Circle the City is adding a 33,000-square-foot respite facility. Mesa also saw a $48.0 million medical office sale in Q2, which tells you institutional capital now views Mesa as a core healthcare submarket rather than a discount alternative.
Scottsdale. Scottsdale sits on the northeast edge of the Valley rather than in the East Valley proper, but it competes for the same specialists and the same referral networks, so tenants should shop it alongside Gilbert and Mesa. It is the premium submarket, and the capital flowing in is extraordinary: Banner is investing more than $400 million in a 384,000-square-foot campus on 48 acres at Hayden Road and the Loop 101, while Dignity Health is planning a 300,000-square-foot outpatient campus near Scottsdale Road and the Loop 101 with roughly 700 medical and support jobs. Mayo Clinic’s $1.9 billion expansion adds 59% more clinical space and over 3,500 jobs by 2031.
None of those projects relieve pressure on tenants who need space in 2027. What they guarantee is that physician population, referral volume, and competition for surrounding suites all grow — a reason to lock in location and term now rather than wait.
National Impact
Arizona is not an outlier. The same supply squeeze is playing out across the Sun Belt, where suburban markets in Florida, North Carolina, and Texas are posting the strongest rent growth in the country. Capital is rotating into medical outpatient buildings precisely because the leases are long, the tenants are sticky, and no one can build competing product at today’s costs.
There is a quiet advantage for tenants in that. Because medical tenants sign longer leases and deliver stable occupancy, landlords and their lenders will pay for that credit — usually as a larger improvement allowance, free rent, or a fixed renewal option. The concession shows up in structure rather than face rent, which is why the rent number alone is a poor way to compare offers.
Key Risks for Healthcare Tenants
- Buildout cost overruns. Long-lead mechanical and imaging equipment can push a schedule past your lease commencement date, leaving you paying rent on space you cannot occupy.
- Underwriting the wrong shell. A cheaper rent in a cold dark shell frequently produces a higher total occupancy cost than a higher rent in second-generation medical space.
- Renewal leverage evaporating. With no new deliveries and falling vacancy, tenants who wait until 90 days before expiration have effectively no alternatives to negotiate against.
- Slower population growth. Maricopa County added 35,411 residents in 2025, a 40% slowdown from its 2021–2022 peak. Build more modest patient volume growth into your space projections rather than over-leasing.
- Parking and access. Clinical uses need materially more parking than office uses. A building that works on paper can fail a patient-experience test on day one.
Key Opportunities
A constrained market still rewards prepared tenants. Four openings are worth pursuing right now.
- Second-generation clinical space. Existing built-out suites save six figures in improvement costs and months of schedule. They are rarely marketed publicly, so they are found through broker relationships, not listing sites.
- Class B conversions in strong locations. With general Phoenix office asking rents at $32.30 per square foot and Class B at $30.60, a well-located office building with adequate power and parking can be converted for a lower all-in cost than premium medical rent over a 10-year term.
- Trading term for capital. Landlords facing an empty suite with no replacement supply will fund improvements for a 10- or 15-year commitment from a strong healthcare credit. Longer term is your most valuable negotiating currency.
- Mesa pricing with Gilbert demographics. The corridors between the two — along the 202 and Loop 101 — offer patient access to both markets at rents below the Scottsdale and North Gilbert premium.
The ICRE Perspective
What we see in the field does not always match what the quarterly reports say. The reports show a market with room. Our tenant clients experience a market with three viable options and a landlord who knows it.
The mistake we watch healthcare tenants make most often is starting too late. A practice signs a five-year lease, gets busy treating patients, and calls a broker four months before expiration. At that point there is no time to build out anything, so the only realistic choice is the landlord’s renewal proposal — which is exactly the outcome the landlord planned for. Twelve to eighteen months of runway is not conservative in this market. It is the minimum required to have any leverage at all.
The second thing tenants underestimate is how much shell condition drives the deal. Two offers modeled side by side — improvement costs, free rent, and operating expenses included — often reverse rank, with the higher-rent building costing less over the term. Face rent is the least informative number in a medical office proposal.
What is being underestimated market-wide is duration. This is not a two-quarter squeeze. With construction costs where they are and health systems committing billions to campuses that will not open until 2028 and beyond, East Valley medical office space stays tight for years. Tenants who secure good locations on long terms now will look smart in 2030.
Tenant and Investor Takeaways
- Begin your search 12 to 18 months before expiration. Leverage is a function of time, not negotiating skill.
2. Model total occupancy cost, not rent. Include improvement costs above the allowance, free rent, operating expenses, and schedule risk.
3. Prioritize second-generation medical suites. They are the fastest and cheapest path to opening, and they go quickly.
4. Use term as currency. A longer commitment buys allowance, free rent, and renewal protection in a no-supply market.
5. Follow the health systems. Banner, Dignity, and Mayo have told the market where patient volume is going. Referral proximity is worth more than a dollar of rent.
6. For owners, the position is strong but not automatic. Buildings with adequate power, plumbing, and parking will lease. Buildings without them will keep sitting inside that 15.1% vacancy number.
Conclusion
The strategic takeaway is that scarcity in this market is qualitative, not quantitative. There is vacant square footage in the East Valley. There is very little space a healthcare practice can actually open in without spending heavily and waiting months. Tenants who understand that distinction shop differently and negotiate better.
Looking forward, expect the squeeze to persist through at least 2028. New supply is not coming, the health system pipeline delivers late in the decade, and the demographic demand behind it is locked in. Rents should continue climbing gradually while the best second-generation suites lease before they are ever advertised.
The action item is straightforward: pull your lease, find your expiration date, and count backward 18 months. If that date has passed, start now. Competing for East Valley medical office space in Scottsdale, Gilbert, and Mesa is a planning exercise long before it is a negotiation.
