Signing a commercial lease is one of those “big moment” steps in business. It can feel like you’re finally making things real - getting the keys, putting up signage, fitting out the space, and welcoming customers.
But a commercial lease can also be one of the biggest legal and financial commitments your business will ever take on. It’s not just about rent. It’s about who pays for repairs, what happens if you need to exit early, whether you’re allowed to run your business the way you plan to, and how much power your landlord has to change the deal later.
That’s where a commercial leasing lawyer can help. A good lawyer helps you understand what you’re signing, negotiate the terms that matter most, and avoid hidden risks that only show up when something goes wrong.
Below, we break down when it’s worth getting legal help, what parts of the lease commonly cause disputes, and how to protect your business from day one.
What Does A Leasing Lawyer Do (And Why It Matters For Small Businesses)?
A leasing lawyer (sometimes called a commercial lease lawyer) helps you deal with the legal side of renting business premises. That can include:
- reviewing a lease before you sign it, and explaining what it really means in practical terms
- negotiating changes (so you’re not just taking the landlord’s “standard” terms)
- checking key documents like an agreement for lease, deed of lease, guarantor documents, and side letters
- helping with lease variations, renewals, assignments, and subleases as your business grows
- advising if there’s a dispute (for example, rent reviews, repair costs, insurance issues, or ending the lease early)
For small businesses, the big advantage is leverage and clarity. Many leases are drafted in a way that protects the landlord’s position first. That doesn’t automatically mean the lease is “unfair” - but it does mean you should understand the risk you’re taking on.
A leasing lawyer NZ businesses trust will also help you match the lease to your business reality. For example, a hospitality venue with high fit-out costs will have very different lease priorities to a consultancy renting a small office.
When Should You Talk To A Leasing Lawyer?
You don’t need to wait until you’re in a legal dispute to speak to a leasing lawyer. In fact, the best time to get help is before you commit - when terms can still be negotiated.
Here are the common “yes, it’s time” moments.
1. Before You Sign Anything (Including A Heads Of Agreement)
Some landlords start with an informal “heads of agreement” or term sheet to confirm the commercial deal. Depending on how it’s drafted and used, it may be intended to be non-binding, partly binding, or create practical pressure to proceed - and it can shape the final lease.
If you’re at this stage, it can be worth getting advice early - especially where you’re agreeing to key figures like rent, term, renewal rights, incentives, and who pays outgoings.
If you already have a draft lease or HOA, a Heads of Agreement review can help you avoid locking in a deal that doesn’t fit your business.
2. When The Lease Has “Standard” Clauses You Don’t Fully Understand
Commercial leases often include clauses that sound routine but carry major cost and risk, such as:
- rent review provisions (CPI, market review, fixed increases)
- outgoings (rates, insurance, maintenance, body corporate charges)
- repair and maintenance obligations
- make-good requirements at the end of the lease
- default clauses (what counts as a breach and what the landlord can do)
If you’re reading the lease and thinking “I think I get it… but I’m not 100% sure”, that’s usually the point where legal help is worth it.
3. If You’re Personally Guaranteeing The Lease
It’s common for landlords to ask small business owners to provide personal guarantees, especially if your business is a new company or doesn’t have a long financial track record.
This is a big deal: it can mean you’re personally on the hook for rent and other losses if the business can’t pay.
A leasing lawyer can explain what you’re agreeing to, whether there are ways to limit the exposure (for example, caps, time limits, or removing guarantees after a period), and what to avoid signing without advice.
4. When You’re Doing A Fit-Out Or Taking Over A Premises “As Is”
Fit-outs often come with hidden legal questions:
- Who owns the fit-out items?
- Do you need landlord consent?
- What standards do the works need to meet?
- What happens if you need to remove everything at the end?
If you’re spending real money on improvements, it’s worth making sure the lease aligns with what you’re building.
5. If You Need Flexibility (Or You Might Need To Exit Early)
Many businesses sign a lease while optimistic - then reality hits. Sales fluctuate. Staffing changes. You realise you need more (or less) space. Or you decide to relocate to a better area.
A leasing lawyer can help you think about exit options upfront, including:
- assignment rights (transferring the lease to a new tenant)
- subleasing rights (renting part or all of the premises to someone else)
- break clauses (ending early under agreed conditions)
- termination rights and the costs involved
If you’re planning to assign later, it’s also helpful to understand how an assigning a lease process usually works in NZ.
Key Commercial Lease Terms A Leasing Lawyer Will Focus On
Every lease is different, but there are a few terms that cause the most headaches for business owners. These are the areas your leasing lawyer will typically scrutinise and negotiate hard.
Rent, Rent Reviews, And Hidden Costs
Rent is the obvious cost, but it’s rarely the only one.
Your leasing lawyer will usually check:
- how rent increases (and how often)
- how “market rent” is determined (and what happens if you disagree)
- what outgoings you pay and whether they’re capped or estimated
- penalty interest for late payments
In practice, it’s often the outgoings and rent review mechanics that surprise tenants - not the base rent figure.
Permitted Use (Can You Actually Run Your Business There?)
Leases typically limit what you can do in the premises through a “permitted use” clause.
This matters more than you might expect. If the permitted use is too narrow, you could be stuck if you need to expand your offering (for example, a cafe adding retail items or a clinic adding new services).
It’s also important for compliance - if you operate outside the permitted use, you may be in breach of the lease.
It’s worth understanding what permitted use means in a commercial lease and how it should be drafted for flexibility.
Repairs, Maintenance, And “Make Good”
Repair obligations are one of the most common dispute triggers, especially at the end of the lease.
Your leasing lawyer will help you understand questions like:
- Are you responsible for structural repairs or only day-to-day maintenance?
- Who pays if major building systems fail (roof, plumbing, electrical, HVAC)?
- What standard do you have to “make good” to at the end?
- Is there an entry condition report (so you can prove the starting condition)?
Make good clauses can be expensive if you need to strip out a fit-out, repaint, replace flooring, or restore the premises to a specific condition. These costs can be significant - and they’re easy to underestimate when you’re focused on opening.
Insurance And Risk Allocation
Commercial leases usually require you to hold certain insurance and to take on certain risks (for example, public liability). They may also attempt to limit the landlord’s liability.
This is where legal advice can really help, because it’s not just a paperwork issue - it’s about what happens if something goes wrong in the premises.
A leasing lawyer may also flag exclusions that try to push risk onto you, and discuss whether the wording lines up with your actual insurance cover.
Assignments, Subleases, And Growth Plans
If your business grows, you might want to:
- take on a business partner
- sell the business
- bring in a franchisee
- sublease part of your premises
Each of these can be affected by your lease terms.
Your lease might require landlord consent to an assignment or sublease, and it may set conditions (for example, the landlord can require financial information about the incoming tenant, or insist on new guarantees).
If you think a change may happen during the lease term, it’s smart to negotiate flexibility early, rather than trying to fix it after you’re locked in.
Common Commercial Lease Problems A Leasing Lawyer Can Help You Avoid
Most business owners don’t get into trouble because they did something reckless. It’s usually because the lease didn’t match what they assumed it said - or because a “standard” clause became painful when circumstances changed.
Here are a few common issues we see.
“I Didn’t Know I Was Responsible For That Cost”
This typically happens with:
- outgoings that weren’t properly explained
- repair and maintenance costs (especially for shared building items)
- after-hours air conditioning or building services charges
- reinstatement/make-good requirements
Legal advice upfront is often far cheaper than dealing with a surprise invoice later.
“My Landlord Won’t Let Me Do What I Need To Do”
This can relate to signage, fit-out changes, operating hours, or the business activities allowed under the permitted use.
A leasing lawyer can help you negotiate clear approval processes and timeframes, so you’re not stuck waiting (or arguing) when you need a quick decision to keep the business moving.
“I Need To Get Out Of The Lease”
If your business needs to exit, the options depend on the lease wording and the landlord’s willingness to negotiate. Sometimes you can assign or sublease, but sometimes there are restrictions or conditions that make it hard.
Depending on the situation, it may also involve negotiating a lease surrender. If you’re heading down this road, having the exit documented properly matters - including making sure you’re released from future liability.
Where a formal exit is being negotiated, a lease surrender agreement can be a key part of wrapping things up cleanly.
“The Lease Doesn’t Match The Deal We Agreed To”
This is more common than you’d think. You might have discussed incentives, rent-free periods, contributions to fit-out, or specific repairs - but if they aren’t documented properly, enforcing them can be difficult.
A leasing lawyer can make sure side deals aren’t left as vague emails or verbal promises, and help you confirm that the lease reflects what you’ve actually agreed.
Lease Review Vs Lease Drafting: What Kind Of Help Do You Need?
Not every business needs a lease drafted from scratch. Most commonly, landlords provide their own lease document and you need a review and negotiation.
Lease Review (Most Common For Tenants)
A lease review is where your leasing lawyer reads the lease, explains the key clauses and risks, and helps you negotiate changes where needed.
If you’ve been given a lease to sign, this is usually the starting point. A Commercial Lease review is designed to make sure you understand the practical impact before you commit.
Lease Drafting (More Common For Landlords Or Special Arrangements)
Lease drafting is where a lawyer prepares the lease document itself. This can be relevant if:
- you own a building and are leasing to another business
- you’re entering into a more tailored leasing arrangement
- the landlord’s lease is outdated or not suitable and needs a full rewrite
If you’re the party preparing the lease, getting it properly drafted is important for clarity and enforceability. This is often handled through a Commercial Lease drafting process.
Agreement For Lease (When You’re Signing Before The Premises Is Ready)
If you’re moving into a new build, a refurbished space, or a premises that isn’t ready yet, you may be asked to sign an agreement for lease first.
This document can set the conditions for when the lease “starts”, and what happens if the premises aren’t delivered on time or to the required standard.
In that case, it can help to get an Agreement for Lease review so you’re not taking on timing or construction risk that should sit with the landlord.
Key Takeaways
- A leasing lawyer can help you understand, negotiate, and manage the legal risks in a commercial lease, including rent reviews, outgoings, repairs, make good, and exit rights.
- The best time to speak to a leasing lawyer is before you sign - once you’re locked in, your options usually become more limited (and more expensive).
- Small businesses should pay close attention to the hidden cost areas of a lease, including outgoings, repair obligations, insurance requirements, and make-good clauses.
- Your lease should match your business model, including your permitted use, fit-out plans, operating needs, and growth plans (like assigning or subleasing later).
- If you may need flexibility, negotiate for it early through clear assignment/sublease clauses, potential break options, and practical approval processes.
- Commercial leasing can feel overwhelming, but with the right legal support you can sign confidently and protect your business from day one.
