The Commercial Lease — The Owner's Guide: Maintenance, Common Areas and Management Fees

Most commercial property owners treat the lease as a document with one purpose: to set the rent and ensure it's received. That's a costly mistake. The commercial lease is the central tool by which you divide maintenance responsibility, define who pays for what in the common areas, and build a management-fee mechanism that can — if written correctly — fund real preventive maintenance instead of reacting to breakdowns. I manage an office building, and most of the disputes I've seen between owners and tenants could have been prevented by one clear contractual clause.

Why the lease is a maintenance document, not just a financial one

An office building is a complex asset: HVAC, electrical, water, elevators, fire detection and suppression, envelope and structure. Each of these wears out, and each requires documented preventive maintenance. The critical question the lease must answer is not "how much will be paid" but who is responsible for maintaining what, and to what standard. When the answer is vague, what actually happens is that no one maintains — the tenant assumes it's the owner's responsibility, the owner assumes it's the tenant's, and the system deteriorates to failure.

I saw it up close: a chiller that failed in summer because both sides believed the other was maintaining it. Both showed me clauses in the contract they thought supported their position — and both were partly right, because the contract was vague. The discussion ended in a painful financial compromise, in damaged relations and in a chiller ruined by the delay in treatment. A clear clause would have cost several orders of magnitude less.

In Israel there's a tendency to act only when an external factor compels — a fire inspector, an insurance company, a local authority. But your property's value is not preserved by the authority; it is preserved by systematic maintenance that begins with a contractual clause. A good contract turns preventive maintenance from a statement of intent into an enforceable commitment.

Dividing maintenance responsibility — the heart of the contract

The guiding principle: the tenant is responsible for what's inside the leased unit and for what's caused by his use; the owner is responsible for the structure, the envelope and the central systems whose service is building-wide. But "what's inside the unit" is precisely where disputes are born, so you must detail it.

What it makes sense to place on the tenant

• HVAC end units: diffusers, filters, cleaning — units that serve only his space. The tenant is the one who determines the usage load, so he is the right party for this maintenance.
• Lighting fixtures and internal electrical accessories: replacing bulbs, sockets, and repairing damage caused by use — damage that can't be attributed to him if there's no clear clause.
• Sanitary plumbing within the unit: sinks, taps and blockages originating in the tenant's use. A blockage in the main pipe — the owner's responsibility; a blockage in the unit's restroom — the tenant's responsibility.
• Use-related damage: damage to the floor, interior walls and infrastructure installed for his needs; reasonable wear and tear is not included in this — it's important to define the "norm" as well.

What must stay with the owner

• Central systems: chillers, pumps, main electrical panels, building-wide generator and UPS. These are assets that affect the value of the entire building.
• Envelope and structure: facade, roof, waterproofing, frame and fire compartments — harming them is harming the asset itself, not just the tenant's comfort.
• Building-wide fire safety: fire pump, fire-detection system, smoke extraction and escape stairs — the Business Licensing Law and the fire-service regulations obligate the owner, not the tenant, in these respects.
• Elevators: monthly service and a certified inspector's check — never to be placed on a single tenant. The Elevators Safety Law obligates the property owner.

The reason the central systems stay with the owner is not generosity — it's control. If a tenant maintains the chiller at poor quality, the one who bears the long-term damage is your property's value. I expanded on this logic in the annual preventive-maintenance checklist, and it's worth attaching it as an appendix to the contract.

The gray areas — where disputes are really born

Beyond the clear division there are "gray areas" every contract needs to address explicitly:

• An HVAC system in a single unit: if the unit has a dedicated split air conditioner (not part of a central system), who maintains it? It's recommended to define that the tenant is responsible for routine maintenance while the owner is responsible for replacement at end of life — and to set the system's age at move-in.
• Electrical conduits and plumbing inside the unit's walls: the piping itself — the owner; damage the tenant caused that harmed it — the tenant.
• Changes made by the tenant: what happens to a drywall partition the tenant erected? Who removes it? It's mandatory to regulate this in a "changes and adaptations" clause and a "restoration to original state" clause.

Standard 1525 and Israeli regulation — a shared language in the contract

Instead of writing "the tenant shall maintain the systems reasonably" — a wording you can't enforce — refer to a recognized professional standard. Israeli Standard 1525 for building maintenance defines a framework for documented preventive maintenance, and you can write in the contract that each party shall maintain its part "in accordance with the principles of Israeli Standard 1525 and the manufacturer's instructions, while keeping a maintenance log". This gives you an objective yardstick: if a dispute breaks out, the question is not "what's reasonable" but "was a log kept and were the checks performed at the required frequency."

Beyond Standard 1525, several specific legal obligations worth anchoring in the contract:

• Periodic electrical inspections: the electricity regulations require periodic inspections by a certified electrician — the owner's responsibility, and documentation of the inspections should be part of the building log.
• Elevators: the Safety at Work (Elevators) Regulations set the service and inspection frequency by a certified inspector. The contract should mention that this cost is included in the management fees.
• Fire-suppression systems: the Fire and Rescue Authority regulations require periodic inspections; the owner's responsibility even if the tenant engages in activity with a high fire load.
• Accessibility: the Equal Rights for Persons with Disabilities Law requires accessibility in the common areas — a direct responsibility of the owner that cannot be transferred to the tenant.

Attaching a standard and regulation to the contract also protects you vis-à-vis the insurance company. If a fault occurred and it turned out that maintenance wasn't performed, a documented log is the first thing they ask for — and it's the difference between insurance coverage and rejection of a claim.

How I implement this in practice

The way I enforce this is a contractual requirement to furnish periodic service confirmations. If the tenant is responsible for the HVAC end units, the contract requires him to present, once a quarter, a signed confirmation from a certified technician who performed cleaning and inspection. This changes the whole dynamic: instead of discovering after the fact that a filter wasn't replaced for two years and the unit burned out, I have an ongoing control mechanism.

The same principle applies on my side — I keep the elevator inspector's confirmations, the electrical inspections and the fire-system service available and organized, because they are a legal asset exactly like the contract itself. When the insurance company comes to examine an incident, the orderly log is what distinguishes a property owner who manages professionally from a negligent property owner in the insurer's eyes.

Common areas — definition, allocation and the sources of dispute

Common areas are everything outside the leased units that serves everyone: the lobby, corridors, stairwells, parking, technical roof, machine rooms, public restrooms and gardening areas. From the owner's perspective, these are the areas where the building's value is measured — a potential tenant is impressed by the lobby long before he sees the unit.

The problem: the cost of maintaining the common areas is divided among all the tenants, and if the division isn't clear, every tenant feels he's paying for his neighbor. So the contract must define precisely:

• Definition of the common areas: a detailed list — preferably with an attached plan — of what's considered common and what's private. A corridor accessed by only two units: common or partly private? You must decide.
• The allocation key: the most transparent method is allocation by relative area — the unit's area divided by the total leased area in the building. You must distinguish between gross and net area and define the measurement method in advance.
• The defined scope of service: what's included — cleaning, common-area electricity, water, lobby HVAC, security, gardening, elevator maintenance. What's not written — isn't included, and will become an argument.
• Preventive maintenance as an integral part: not only daily cleaning but periodic inspections of the common systems — and stating in the contract that their cost is included in the management fees.
• Different operating times and loads: if one tenant works on Saturday and the rest of the building is closed, who bears the cost of operating the HVAC and lobby during those hours? It's worth setting an explicit mechanism.

Managing common areas in a multi-tenant building is a challenge in itself, especially when there are tenants with different operating hours and conflicting needs. I expanded on this in the challenges of managing a multi-tenant building.

Management fees — not a tax, but a planned maintenance budget

The most common mistake I see: owners who treat management fees as an additional income source, and tenants who treat them as a burdensome tax. Both are wrong. Correct management fees are a planned budget that covers the cost of operating and routinely maintaining the building — and when priced correctly, they serve all sides.

What management fees should cover

• Routine operation: common-area electricity, water, cleaning, security, gardening.
• Service contracts for systems: elevators, central HVAC, fire detection and suppression, generator — annual maintenance contracts with certified service providers.
• Mandatory periodic inspections: a certified inspector for elevators, electrical inspections, fire systems.
• Management and documentation: the management fee, maintaining maintenance logs, vendor management and supervision.

The clause most contracts forget — a maintenance reserve fund

Management fees that cover only routine expenses ignore the engineering truth: systems wear out and eventually require capital replacement. A chiller, an elevator or an electrical system don't break down in a convenient gradual way — they reach end of life and deliver expensive surprises. A responsible contract includes a mechanism for gradual accumulation into a maintenance reserve fund, so that when the day comes there's no need for a one-time levy. Without it, you as the property owner are left with the whole bill at the most inconvenient moment.

It's also important to establish transparency: the tenants are entitled to see where the management fees go. A simple annual report detailing the actual expenses — operation, service contracts, inspections, the fund — prevents suspicion and builds trust. In my experience, a tenant who sees the breakdown accepts the charge without argument; a tenant who pays an "unclear fixed sum" will contest every increase.

Fixed versus variable — how to price correctly

A common planning mistake is to price management fees as one fixed sum and forget that part of the costs is consumption-dependent. Electricity and water of the common areas vary by load and season — the Israeli summer sends the lobby's HVAC consumption soaring considerably. A healthy mechanism separates between:

• A fixed component: annual service contracts, cleaning, security, the management fee — known in advance and stable.
• A variable component: common-area electricity and water — settled by actual consumption, preferably quarterly.
• A maintenance-reserve component: a fixed percentage of the total management fees that is accumulated and not refunded at year's end.

A question that always comes up: what happens when a unit stands empty? During a vacancy period the owner is the one who bears the proportional share of the management fees for that unit — you can't roll it onto the other tenants without harming the fair key. It's worth planning the management budget on a realistic occupancy assumption rather than a maximal one — a building always calculated as if it were 100 percent full runs into difficulties in every tenant-turnover period.

Self-management or a management company — the contractual implication

The contract should address the question of who actually manages the building. If you manage it yourself, the contract defines your duties directly toward the tenant — including response times for faults and the manner of reporting. If you hired a management company, the contract should refer to it and set a measurable service standard: response time for an urgent fault versus a routine one, report frequency, who is the responsible party on the company's behalf.

The distinction between property management and facility management matters here — I explained it in property management versus facility management. In short: property management deals with the economic-contractual aspect; facility management with the engineering-maintenance aspect. An office building needs both, and the contract should ensure both are covered — otherwise one of them falls between the cracks.

If you're considering handing management to an external company, the right choice is critical — a cheap company that skimps on preventive maintenance will cost you far more in long-term damage. I gathered criteria in how to choose a property management company.

Handover and receipt — the documentation that prevents the next dispute

The most critical moment in the contract's life that's usually not written into it is the unit-handover day. I don't hand over or receive a unit without a handover protocol documented in writing and photos. My protocol includes:

• The condition of the floor, walls, ceiling and the unit's interior — photos of every wall.
• The HVAC units serving the unit — last service date and filter condition.
• Electrical points, meter numbers (electricity, water if separate) — a reading and a photo.
• The condition of windows, doors, locks and fixtures.
• Every known existing defect — marked and agreed upon by both parties before the handover.

Without opening documentation you have no basis to demand restoration to the original state at the end of the tenancy — every argument about damage becomes "word against word." A good handover protocol is the cheapest insurance you'll take out, and I recommend signing it in the presence of both parties — not sending an email and hoping for confirmation.

The same logic applies to systems. If the tenant receives an HVAC unit that has just been serviced, record it — so at the end of the tenancy it's clear what the initial state was and what deteriorated under his use. In a multi-tenant building, where units turn over at a different pace, this documentation is what preserves the continuity of engineering knowledge about the asset — information that's lost very quickly when there's no systematic documentation.

Clauses many contracts forget

• Restoring the leased unit to its original state: a clear definition of the unit's state at the end of the tenancy, including the obligation to dismantle additions the tenant made — and a date for doing so before the departure day.
• Changes and adaptations: who approves structural changes (partitions, openings, connections) and who is responsible for their implications on the building's systems. A change made without approval — at the tenant's expense in any case.
• Accessibility in the common areas: responsibility for compliance with the requirements of the Equal Rights for Persons with Disabilities Law — the owner's responsibility in the common areas, even if the tenant made changes inside.
• Business licensing: an explicit clarification that compliance with the conditions of the tenant's business license (Business Licensing Law, 5728-1968) is his exclusive responsibility, but the building infrastructure required for it — for example an emergency exit, ventilation — is the owner's responsibility.
• Access for maintenance: the owner's or the management company's right to enter the unit for the purpose of maintaining common systems and safety inspections — subject to reasonable advance notice (usually at least 48 hours, except in emergencies).
• Liability for third-party damage: if a fault in the tenant's unit caused damage in a common area or an adjacent unit — who bears it. This clause prevents complex insurance arguments.

The maintenance-access clause is especially important and usually forgotten: if a sprinkler, a main pipe or an electrical panel passes through a leased unit, you must have an anchored right of access — otherwise you can't fulfill your maintenance duties, and worse: in an emergency you'll discover you can't enter.

Bottom line for the property owner

The commercial lease is your property value's first line of defense. It divides responsibility, defines the common areas, and builds a management-fee mechanism that can fund real preventive maintenance — if you write it that way. Don't treat it as a purely financial document; it is an engineering-legal document that defines how the building will be maintained for years to come.

A combination of five elements is what distinguishes a contract that preserves an asset from one that leads to deterioration:

• A detailed division of responsibility — including gray areas specific to your property.
• Attaching Standard 1525 and relevant regulation — an objective yardstick everyone understands.
• A transparent allocation key for common areas — with an attached plan and a clear calculation mechanism.
• Management fees that include a maintenance reserve fund — and transparent accounting to the tenants.
• A documented handover protocol — that forms the basis for every future argument.
