If your company is sitting on unused office space—or searching for flexible workspace without a long-term commitment—a sublease might be your answer. But before you jump in, it’s important to understand what subleasing really means, how it works, and what risks come with it.
In this guide, we’ll break down everything you need to know about subleasing commercial office space—and show you how Interior Avenue’s Easy Spaces program can turn sublease opportunities into fully furnished, move-in-ready solutions that benefit everyone involved.

What Is a Sublease?
A sublease (also called a sublet) is when a tenant leases out all or part of their rented office space to another party—called the subtenant—during the remaining term of their lease.
Here’s how it works:
- The original tenant (sublessor) holds the master lease with the landlord
- The subtenant (sublessee) rents directly from the original tenant, not the landlord
- The original tenant remains legally and financially responsible to the landlord
Think of it like renting a room in an apartment you’re already leasing. You’re still on the hook for the full rent—even if your subtenant doesn’t pay.
Why Do Companies Sublease Office Space?
There are several common reasons a company might choose to sublease:
1. Downsizing or Going Hybrid
After the pandemic, many companies shifted to remote or hybrid work models and no longer need as much physical space. Subleasing helps them reduce overhead without breaking the lease.
2. Relocating Before Lease Ends
A company may outgrow their current space or need to move to a new market—but still have years left on their lease. Subleasing allows them to exit early without paying the full lease term upfront.
3. Cost Recovery
Even if a company isn’t using the space, they’re still paying rent. Subleasing some or all of the space helps offset those monthly costs and can sometimes even generate profit.
4. Avoiding Lease Penalties
Breaking a lease often comes with steep financial penalties. Subleasing offers a way to fulfill the lease obligation while reducing financial risk.
Why Subleases Matter to the CRE Market
Subleases aren’t just a tenant issue—they’re a key indicator of market health and opportunity.
Shadow Vacancy: The Hidden Metric
Rising sublease listings can signal shadow vacancy—a hidden indicator of market softness that doesn’t show up in traditional vacancy reports. Shadow vacancy represents space that’s technically leased but no longer occupied or utilized by the original tenant.
This matters because shadow vacancy often predicts:
- Economic uncertainty or market downturns
- Weakening demand for office space
- Future increases in official vacancy rates
- Potential rent pressure as more space becomes available
For brokers, landlords, and investors, tracking sublease activity provides early warning signals about market conditions that standard metrics might miss. A spike in sublease availability often appears six to twelve months before traditional vacancy rates reflect similar trends.
Opportunities for Subtenants
While rising subleases may signal market challenges, they create significant opportunities for companies seeking office space. Subleases often come with attractive benefits:
- Lower rent than direct leases, since sublessors are motivated to fill the space quickly
- Shorter lease terms for companies that need flexibility or want to test a market
- Move-in-ready spaces that may already include furniture, technology infrastructure, or custom buildouts
- Access to premium locations in Class-A buildings that might otherwise be unavailable or unaffordable
- Reduced or negotiable security deposits compared to direct leases

The Risks and Challenges of Subleasing
While subleasing can be a smart financial move, it’s not without complications. Both parties face unique challenges.
For the Original Tenant (Sublessor)
You’re Still Liable
Even if your subtenant stops paying rent, you remain responsible for the full lease payment to the landlord. If the subtenant damages the space or violates lease terms, you could face repair costs, penalties, or even eviction—all while still paying rent.
Landlord Approval Required
Most commercial leases require landlord consent before subleasing. The landlord may reject your proposed subtenant based on creditworthiness, business type, or other criteria. Some landlords also require additional security deposits or charge administrative fees for sublease approval.
Furniture and Fit-Out Costs
If your space is empty, outdated, or configured for your specific operations, you may need to invest in furniture, reconfiguration, or improvements to make it marketable to prospective subtenants. These costs can significantly reduce—or eliminate—any cost savings from subleasing.
Marketing and Vacancy Risk
Finding a qualified subtenant takes time, effort, and often money for broker fees or advertising. The longer your space sits vacant, the more you lose. In soft markets, sublease spaces can sit empty for months while you continue paying full rent.
Complicated Exit Strategy
If your subtenant wants to renew but your lease is ending, or if you want to return to the space but your subtenant has a valid sublease agreement, navigating these scenarios can create legal and financial complications.
For the Subtenant (Sublessee)
Limited Control
You’re not dealing directly with the landlord, which can complicate maintenance requests, building access issues, lease changes, or lease extensions. You’re dependent on the original tenant to relay information and handle landlord relationships.
Lease Term Restrictions
Your sublease can only last as long as the original tenant’s lease. If you need long-term stability or are planning for growth, a sublease with only 12-18 months remaining may not provide the security you need.
Risk of Eviction
If the original tenant defaults on their master lease, the landlord can terminate the agreement—and you could be forced to vacate, even if you’ve paid your rent on time and followed all terms. You have limited legal recourse in this scenario.
Uncertain Condition of Space
Sublease spaces are typically offered “as-is,” meaning you may inherit outdated furniture, poor layouts, worn finishes, or deferred maintenance issues. Unlike a direct lease where you can negotiate tenant improvements, sublease spaces rarely come with landlord-funded upgrades.
Ambiguous Responsibilities
Who handles repairs? Who pays for cleaning? What happens if building systems fail? These questions aren’t always clearly answered in sublease agreements, leading to disputes and unexpected costs.

How Interior Avenue’s Easy Spaces Program Solves Sublease Challenges
Whether you’re a tenant trying to sublease your unused space or a subtenant looking for a flexible, move-in-ready office, Interior Avenue’s Easy Spaces program makes the process faster, easier, and more profitable for everyone involved.
1. Turn Vacant Space Into a Furnished, Turnkey Sublease
If you’re a sublessor with an empty or outdated suite, Easy Spaces can transform it into a fully furnished, Class-A office in just 2–3 weeks—without requiring a huge capital investment.
We provide everything needed for a professional, functional workspace: modern workstations and private offices, conference room furniture with professional presentation capabilities, reception desks and lounge seating that create strong first impressions, and kitchenette and breakroom furnishings that support daily operations.
A furnished sublease is far more attractive to prospective subtenants—and can command higher rent while filling faster. In competitive sublease markets, a turnkey solution often means the difference between sitting vacant for six months or leasing within weeks.
2. Flexible, Subscription-Based Furniture
With Easy Spaces, furniture becomes an operational expense, not a capital cost. This means no $30K–$75K upfront furniture investment that you’ll struggle to recoup. Instead, you pay monthly subscription fees that align perfectly with your sublease term—whether that’s six months, two years, or longer.
The furniture can be added, removed, or reconfigured as your needs change. If your subtenant needs more desks mid-lease, we add them. If they shift to hybrid and need less, we remove them. This flexibility protects you from overinvesting in fixed assets you can’t easily liquidate.
For sublessors, this approach means you can offer a furnished space without the financial risk of buying furniture you’ll only use temporarily. For subtenants, it means you get professional furniture without long-term commitments that extend beyond your sublease term.
3. Fast Turnaround to Reduce Vacancy
Time is money in subleasing. Every month your space sits empty is a month you’re paying rent with zero recovery. Every week a subtenant spends searching is another week they’re paying for space they can’t use yet.
Interior Avenue delivers and installs furniture in as little as 14–21 days, which means you can list your sublease faster with professional photos and virtual tours, start showing the space to prospective tenants sooner with a move-in-ready presentation, and begin collecting rent weeks or even months earlier than if you waited for traditional furniture procurement.
For subtenants, this rapid turnaround means you can move your team in and become operational almost immediately—critical when you’re trying to onboard new employees, meet client deadlines, or simply stop paying for two spaces simultaneously.
4. Scalable Solutions for Any Size Sublease
Whether you’re subleasing a 500-square-foot executive suite or 5,000 square feet of open-plan workspace, Easy Spaces is modular and scalable. We can furnish a single office suite for a solopreneur or consultant, half a floor for a growing startup, or an entire floor for an established company needing temporary space.
And if your sublease tenant’s needs change mid-term—they hire faster than expected, they go hybrid and need less space, or they want to reconfigure for collaboration—we adjust the furniture package accordingly. You’re never locked into a static solution that doesn’t match current reality.
5. Zero Hassle at Lease End
When the sublease term ends—or when the master lease expires—furniture becomes a major headache. You can’t easily resell commercial furniture. Storage is expensive. Moving it to a new location costs thousands. And disposal creates environmental concerns.
Interior Avenue handles everything: furniture removal and decommissioning at no additional cost, cleaning and minor repairs to help you meet lease-end obligations, and optional reinstallation at your next location if you’re relocating rather than simply exiting.
Sublessors walk away clean without resale hassles or disposal fees. Subtenants avoid the nightmare of liquidating furniture they only needed temporarily. And everyone saves money, time, and stress.
For Landlords and Brokers: Activate Sublease Inventory Faster
If you’re managing a building with rising sublease availability, Easy Spaces helps you turn a potential problem into an opportunity.
Stage Sublease Spaces
Empty sublease spaces are hard to lease. Prospective tenants can’t visualize the potential, and vacant suites create the impression of a struggling building. We can stage sublease spaces to look occupied, professional, and inviting during tours—dramatically improving lease-up rates.
Offer Furnished Sublease Options
Many prospective tenants—especially startups, remote teams transitioning to office space, and project-based companies—specifically seek furnished options. By partnering with Easy Spaces, you can offer turnkey furnished subleases that attract a wider pool of prospects and command premium rates.
Reduce Shadow Vacancy
Shadow vacancy hurts everyone: tenants paying for space they don’t use, landlords facing future vacancy when those leases expire, and brokers struggling to manage client expectations. By making sublease spaces more marketable through furniture solutions, you help activate that space and reduce long-term vacancy risk.
Support Existing Tenants
When your existing tenants struggle to sublease their space, it creates financial pressure that can lead to defaults. By connecting them with Easy Spaces, you help them become successful sublessors—protecting their financial stability and your rental income stream.

Smart Questions to Ask Before Subleasing
If You’re the Sublessor (Original Tenant)
Before committing to a sublease strategy, ask yourself and your advisors these critical questions:
- Does my lease allow subleasing? What’s the approval process and timeline?
- What are the landlord’s requirements for subtenant creditworthiness or financial guarantees?
- Will I need to provide furniture or improvements? What’s the cost versus benefit?
- How much rent can I realistically charge in the current market?
- What are my financial and legal risks if the subtenant defaults or damages the space?
- Should I hire a broker, or can I market the space myself?
- How will I screen prospective subtenants to minimize risk?
If You’re the Subtenant (Sublessee)
Before signing a sublease agreement, protect yourself by asking:
- How much time remains on the master lease? Is that enough for my needs?
- Is the space furnished? If not, what’s included and what will I need to provide?
- Who handles maintenance, repairs, and building-related issues?
- What happens if the original tenant defaults on their master lease?
- Can I renew or extend the sublease if needed? What are the terms?
- Are there any restrictions on how I can use the space?
- What’s my liability for existing damage or wear and tear?
- Is the sublease rent competitive with direct leases in the market?
Sublease Market Trends in Phoenix Metro
The Phoenix metropolitan area—including Gilbert, Chandler, Mesa, Tempe, Queen Creek, San Tan Valley, and Apache Junction—has experienced significant commercial real estate growth over the past decade. However, sublease activity has increased as companies adapt to new work patterns and economic conditions.
Several factors are driving sublease availability in the region:
Hybrid Work Adoption: Many Phoenix-area companies have embraced permanent hybrid or remote-first models, reducing their space needs by 20-40%. Rather than break leases signed pre-pandemic, they’re subleasing excess space.
Corporate Relocations and Consolidations: As companies relocate headquarters or consolidate regional offices, they’re leaving behind committed lease obligations that sublease markets must absorb.
Economic Uncertainty: In periods of economic uncertainty, companies become more cautious about long-term real estate commitments, making subleases attractive for their flexibility and typically lower costs.
For tenants trying to sublease, this means increased competition and potentially longer vacancy periods. For subtenants, it means more options, better negotiating leverage, and opportunities to access quality space at below-market rates.
Understanding these trends helps both parties set realistic expectations and pricing strategies.
Final Takeaway: Make Subleasing Work for You
Subleasing can be a smart financial and strategic move—but only if you understand the risks, responsibilities, and opportunities involved. Whether you’re trying to offload unused space, recover costs, or find flexible workspace without long-term commitment, success depends on preparation, realistic expectations, and the right partners.
The biggest mistake companies make is treating subleases like simple transactions. They’re not. They’re complex arrangements that require clear communication, proper documentation, risk management, and often creative problem-solving around furniture, space configuration, and market positioning.
Interior Avenue’s Easy Spaces program removes the most common barriers to successful subleasing by providing flexible, professional furniture solutions that align with sublease timelines and budgets. We turn vacant or outdated spaces into marketable, move-in-ready offices—fast, affordably, and without capital investment.
