When you start looking at office spaces in Gilbert, Chandler, or Phoenix, you’ll see listings labeled “Class A,” “Class B,” or “Class C.”
The labels sound like grades, which they kind of are. But “Class A” doesn’t mean “luxury only for the rich.” And “Class C” isn’t automatically a bad deal. The differences are real—and they matter for your lease decision—but understanding them helps you pick the right space at the right price for your business.
This guide explains what each class actually is, why the distinctions matter for Arizona businesses, and how to choose the class that fits your needs and budget.

The Core Definition: Class A, B, and C Offices
Commercial real estate classifies office buildings on a spectrum based on age, condition, amenities, location, and tenant quality. There’s no official governing body that certifies buildings—local brokers and appraisers use market standards. But the definitions are consistent enough that they work across Phoenix, Chandler, Gilbert, and the wider U.S. market.
Class A: Newest, Premium Locations
What you’re looking at:
- Built in the last 10–15 years (typically 2010 or newer in Phoenix)
- Prime locations (downtown Scottsdale, Chandler Riverbend, Gilbert Spectrum, central Phoenix)
- Modern finishes and systems (HVAC, electrical, Wi-Fi infrastructure)
- High-end amenities (modern fitness center, concierge services, rooftop space, upscale lobby)
- Well-maintained exterior (landscaping, parking facilities, architectural appeal)
- Strong management and reputation in the market
Rent range in Phoenix Southeast Valley (2025):
- Gilbert/Chandler: $1.60–$2.00 psf/year
- Central Phoenix: $1.80–$2.40 psf/year
- Tempe: $1.50–$1.80 psf/year
Typical tenants: Growing tech companies, professional services (law, accounting, consulting), healthcare practices, financial services, corporate satellite offices.
Real example: Chandler Riverbend office parks (newer Class A buildings built 2015–2020) rent at $1.85–$2.00 psf. Tenants are tech companies (software, fintech), professional services firms, healthcare. The buildings have Tesla charging, modern fitness centers, collaborative outdoor spaces.
Class B: Solid, Mid-Range Buildings
What you’re looking at:
- Built 15–25 years ago (typically 2000–2010 in Phoenix)
- Good locations, but not prime (secondary corridors, light industrial areas bordering office, suburban office parks)
- Functional finishes (adequate HVAC, decent lobby, standard parking)
- Basic amenities (break room, meeting spaces, some newer buildings have fitness facilities)
- Well-maintained but dated (carpet from 2008, updated paint but older fixtures)
- Dependable management, stable tenancy
Rent range in Phoenix Southeast Valley (2025):
- Gilbert/Chandler: $1.35–$1.65 psf/year
- Central Phoenix: $1.45–$1.75 psf/year
- Tempe/Mesa: $1.30–$1.55 psf/year
Typical tenants: Small-to-mid established businesses (accounting firms, family-owned companies, insurance brokers, medical offices, professional services), nonprofits, government contractors, startups with budget constraints.
Real example: Older Gilbert office parks built in the late 1990s–early 2000s rent at $1.40–$1.55 psf. Tenants include small CPA firms, insurance agencies, engineering firms, medical and dental practices. Buildings are functional and clean, but interiors feel dated compared to Riverbend.
Class C: Older, Budget Buildings
What you’re looking at:
- Built 25+ years ago (typically pre-2000 in the Phoenix area)
- Available locations, often near older commercial districts or transitional neighborhoods
- Older finishes (original fixtures, dated HVAC, limited tech infrastructure)
- Minimal amenities (basic lobby, older parking lots, limited meeting spaces)
- May require periodic maintenance; older systems
- Owner may be less active in market positioning
Rent range in Phoenix Southeast Valley (2025):
- Gilbert/Chandler: $1.15–$1.40 psf/year
- Central Phoenix: $1.25–$1.50 psf/year
- Mesa/South Phoenix: $1.10–$1.35 psf/year
Typical tenants: Budget-conscious businesses, nonprofits with limited space budgets, industrial-adjacent tenants, specialized uses (call centers, training facilities), government agencies.
Real example: Older West Phoenix office parks built in the 1990s rent at $1.15–$1.30 psf. Tenants include nonprofits, call centers, training companies, light industrial businesses using office space. These are functional spaces but require basic updates.
Why the Class Distinctions Matter (Beyond Rent)
Yes, Class A is more expensive than Class B, which is more expensive than Class C. But the differences go deeper than rent per square foot.
1. Employee Attraction and Retention
Your office location and building quality influence your ability to hire and retain talent—especially in competitive fields like tech and professional services.
A software engineer choosing between two companies might pick the one with the Class A office (modern, convenient, good amenities) over a Class B alternative, even with equal salaries. Phoenix’s Southeast Valley (particularly Chandler and Gilbert) has seen significant growth in tech hiring, and many companies relocate specifically to Class A Chandler/Gilbert parks to attract talent from the West Valley.
Conversely, if your business is mature and talent is stable (established law firm, medical practice), the Class B savings ($0.20–0.30 psf × 10,000 sq ft = $2,000–3,000/year savings) often outweigh the amenity differences.
2. Tenant Improvement Allowances (TIA)
Class A landlords typically offer higher TIA (5–10 sq ft worth of buildout) because they’re competing aggressively for tenants and expect long lease terms.
Class B landlords offer moderate TIA (3–6 sq ft), and Class C landlords minimal or no TIA (you get the space as-is).
If you’re moving into a space and need to customize the layout, finishes, or tech infrastructure, the landlord’s TIA can offset much of your buildout cost.
Example:
- Class A Chandler space: $1.90 psf, 10 sq ft TIA (worth $19/sq ft = $190,000 for 10,000 sq ft)
- Class B Gilbert space: $1.45 psf, 4 sq ft TIA (worth $12/sq ft = $120,000 for 10,000 sq ft)
- Net rent after TIA value: Class A = $1.71 effective psf, Class B = $1.33 effective psf
The Class A looks more expensive until you factor in what the landlord is giving you for buildout.
3. Technology Infrastructure
Class A buildings are built with modern tech in mind: high-speed fiber internet built into the structure, backup power systems, modern HVAC with zone control (important for hybrid schedules), structured cabling for video conferencing.
Class B buildings have adequate tech but may require upgrades. Class C buildings may have limited infrastructure (you might need to add your own internet redundancy, HVAC may be less flexible for zones).
For tech companies, consulting firms, or any business doing video conferencing and cloud work, the tech infrastructure of a Class A building reduces your IT setup costs.
For traditional businesses (medical office, accounting firm, legal practice) where tech is standard but not central, the Class B or C tech infrastructure is usually fine.
4. Maintenance and Surprise Costs
Class A buildings have active management, predictable maintenance schedules, and newer systems with warranties.
Class B buildings usually have good maintenance, but older HVAC systems may fail (expensive repair), roofs may be aging, etc. Your lease will specify whether you pay for these or the landlord does.
Class C buildings sometimes shift more maintenance responsibility to tenants. An older roof leak in a Class C building might be your problem.
This isn’t a dealbreaker, but if you’re on a tight budget and can’t afford surprise $5,000–10,000 maintenance bills, Class A eliminates this uncertainty.
5. Subletting and Assignment
If you grow faster than expected and want to sublease part of your space, or if you want to relocate and assign your lease to another tenant, a Class A building with strong demand makes this easier. A Class C building in a slow market makes subletting difficult.
This is a longer-term optionality issue, but it matters for growing companies.
Which Class Is Right for Your Business?
Use this framework:
| Your Situation | Best Class | Why |
|---|---|---|
| Tech startup, 20–50 people, hiring aggressively | A | Modern space attracts talent; strong landlord support for growth |
| Professional services firm (law, accounting, consulting), established | B or A | B saves cost; A attracts clients/talent. Depends on your market positioning |
| Medical/dental practice, 10–20 people | B | Adequate amenities, professional appearance, lower cost than A |
| Nonprofit or government contractor, tight budget | C | Functional space, lowest cost, adequate for stable operations |
| Growing company, unsure if you’ll stay in same location | A | Easier to sublet/assign if you outgrow or relocate; landlord cooperation for changes |
| Mature company, stable headcount, cost-focused | B | Sweet spot of cost and amenity; you know what you’re getting |
| Specialized operations (call center, training, light industrial) | C | Cost-driven; these operations don’t require premium finishes |
Class Breakdown by Phoenix Southeast Valley Submarket
Chandler and Gilbert: Heavy Class A Inventory
Chandler and Gilbert have seen significant development since 2010, especially in the Riverbend area (Chandler) and Spectrum office park area (Gilbert). These submarkets are dominated by Class A inventory.
Class A examples:
- Chandler Riverbend (Guadalupe near Loop 101): $1.85–$2.00 psf, modern buildings 2015+, tenant base is tech, healthcare, professional services
- Gilbert Spectrum: $1.70–$1.95 psf, newer buildings 2012+, similarly modern tenant base
- Downtown Chandler: $1.75–$1.90 psf, mixed-use with office, retail, restaurants
Class B options:
- Older Gilbert/Chandler parks (late 1990s–2000s): $1.40–$1.60 psf, functional and maintained, smaller but stable tenant base
- Tempe near ASU: $1.45–$1.70 psf, age-mixed, some older ASU-related buildings (Class B), some newer builds (Class A)
Class C options:
- Rare in Chandler/Gilbert; these markets are newish and upgraded. Class C would be older pre-2000 buildings at the edges of these suburbs.
Market context: If you’re moving to Chandler or Gilbert because you want a modern location (for talent or market positioning), you’re implicitly choosing Class A in most cases. The cost difference ($1.90 vs. $1.40) is real but manageable if you value the location.
Tempe: Mixed Inventory
Tempe has a mix because of ASU’s footprint. Older buildings near ASU are Class B, sometimes Class C. Newer developments further from campus are Class A.
Class A examples:
- New office parks south of US-60: $1.65–$1.85 psf, similar to Gilbert/Chandler newer inventory
Class B/C mix:
- ASU-adjacent areas: $1.35–$1.60 psf, range reflects building age and condition; many are 2000s-era
Market context: Tempe is more affordable than Chandler/Gilbert for Class A and has a younger vibe due to ASU. It’s a good compromise for startups wanting a modern space without the premium cost of Riverbend.
Mesa and South Phoenix: Class B/C Dominated
Mesa and South Phoenix have less recent development and are more Class B/C.
Class B: $1.30–$1.50 psf, functional buildings from 1990s–2000s, stable tenancy
Class C: $1.15–$1.35 psf, older stock, budget-conscious tenants
Market context: If cost is paramount and you don’t need a Class A location for talent attraction, Mesa offers solid Class B at lower rates than Chandler. South Phoenix has Class C options at very low cost, but you’re accepting older infrastructure.
What Class A Costs in 2025: A Real Breakdown
Let’s look at actual rent, TIA, and operating costs for a 5,000 sq ft office.
Class A, Chandler Riverbend, $1.90 psf/year:
- Annual rent: 5,000 × $1.90 = $9,500/year
- Monthly rent: $792/month
- Typical NNN (operating costs): $0.40–0.50 psf/year = $2,000–2,500/year ($167–208/month)
- Total monthly cost: $960–1,000/month
- TIA value: 5,000 × 8 psf = $40,000 in buildout
Class B, Gilbert, $1.45 psf/year:
- Annual rent: 5,000 × $1.45 = $7,250/year
- Monthly rent: $604/month
- Typical NNN: $0.30–0.35 psf/year = $1,500–1,750/year ($125–146/month)
- Total monthly cost: $730–750/month
- TIA value: 5,000 × 4 psf = $20,000 in buildout
Class C, South Phoenix, $1.20 psf/year:
- Annual rent: 5,000 × $1.20 = $6,000/year
- Monthly rent: $500/month
- Typical NNN: $0.20–0.25 psf/year = $1,000–1,250/year ($83–104/month)
- Total monthly cost: $583–604/month
- TIA value: $0–5,000 (as-is, no buildout)
The premium for Class A: $250–400/month vs. Class B for a 5,000 sq ft space. Over a 3-year lease, that’s $9,000–14,400. Is the modern space, amenities, and talent attraction worth it for your business?
FAQ: Building Classes
Q: Does “Class A” mean the building is perfect?
No. Class A means newer, modern finishes, good amenities, prime location. Buildings can have Class A designation and still have operational issues. Your tenant rep or broker should assess building management, tenant stability, and maintenance practices, not just the class label.
Q: Can a Class B building be better than a Class A building?
Yes, in specific ways. A well-maintained Class B building with newer management, strong tenant base, and lower cost can be a better value than a Class A building with mediocre management and a weak tenant base. Don’t pick purely on class; assess the specific building.
Q: If I move to a Class A space, will it help me attract clients?
It depends on your business. For professional services (law, accounting, consulting), client perception of your office matters moderately; Class A signals stability and professionalism. For tech companies or startups, clients care less about your office and more about your product. For agencies (design, creative, marketing), Class A is worth it because clients expect modern environments.
Q: Will a Class C space limit my growth?
Not operationally, but potentially strategically. If you outgrow the Class C building and want to move to Class A to attract talent or clients, you’re making a move. If you’re planning to stay in one location for 5–7 years and you’re in Class C now, consider whether you’ll regret it later.
Q: I’m in Class A but want to downgrade to save money. What should I worry about?
Going from Class A to Class B is usually fine; you keep most of the functionality and save 20–30% in rent. Going from Class A to Class C is a bigger cultural change for your team. Assess employee morale carefully. If your team values the modern space and you downsize to older infrastructure, you might face retention issues.
Q: Are operating costs (NNN) different in Class A vs. Class B?
Yes. Class A buildings have higher operating costs ($0.40–0.60 psf/year) because of newer systems, more amenities, and active management. Class B runs $0.30–0.40 psf/year. Class C is $0.20–0.30 psf/year. Factor this into your total rent calculation.
Q: If I want to relocate in 3 years, should I pick Class A?
Yes, slightly. Class A buildings have stronger demand and more subleasing/assignment options. Class B/C buildings in slow markets are harder to sublease. If you’re unsure about long-term stay, Class A gives you more flexibility to exit.
The Practical Next Step: Class Selection for Your Search
If you haven’t started looking yet:
Decide which class makes sense for your business using the framework above. Share this with your tenant rep or broker. They’ll show you 5–8 buildings at your chosen class level and comparable alternatives at adjacent classes so you can see the differences yourself.
If you’re already in a lease and considering renewal or relocation:
Review your current building’s class. Are you happy with it? If yes, your renewal offer should reflect that class level. If no (too expensive, too dated, amenities don’t matter), your new search should target a different class.
The key: Class is one factor among many (location, specific building, lease terms, tenant community). Don’t pick class in isolation. Pick class based on your business needs, then evaluate specific buildings within that class.
