HOA Dues on Vacant Units: Rules, Fairness and Calculation

A vacant unit is usually not exempt from building charges (HOA dues or service charges): its owner still shares in the fixed costs and the upkeep of common areas. What can reasonably be reduced is only the usage-based part, such as shared water or per-person cleaning, and only by a decision of the owners’ general meeting or under the building’s bylaws.

Few buildings have never argued about charges on an empty unit. An owner who has not rented out their apartment for months says, “Nobody lives there, so why should I pay the same as everyone else?” The neighbors reply, “The elevator, the caretaker and the building insurance didn’t stop for your unit.” Both sides have a point. This guide explains what common practice and the legal framework generally say, which fair options a building manager has, works through a hypothetical numeric example step by step, and finally shows how to record the decision in building management software so the argument does not restart every month.

What Counts as a Vacant Unit, and Why Is It Disputed?

The monthly charge is each unit’s share of the building’s common costs. A “vacant” or “unoccupied” unit is one where nobody lives during a given period: the owner lives in another city, the unit is being prepared for sale or rent, or it is under renovation. The dispute begins because some building costs really do depend on people being present and others do not. If those two groups are not separated, any decision will leave one side unhappy.

Do Owners of Vacant Units Have to Pay HOA Dues? What the Law Generally Says

The answer depends on where the building is. In Iran, multi-unit buildings are governed mainly by the Apartment Ownership Law and its implementing regulations, and the common reading among lawyers is that not using the common areas does not release an owner from paying their share, because maintaining the building protects the value of every unit, including the empty one. Condominium and HOA rules in many other places follow a similar logic. At the same time, for costs tied directly to residents’ consumption, the owners’ meeting is usually left room to set a fair rule.

This article is not legal advice. Before any decision, read your building’s bylaws and the minutes of past general meetings, check the law that applies locally, and in disputed cases consult a lawyer familiar with building matters. If the board’s duties and the meeting’s authority are unclear to you, our guide to running a building general meeting is a good place to start.

Split Building Costs into Two Groups

The key to a fair decision is to break the monthly cost list into two groups before discussing vacant units at all:

Once costs are split, the question “should a vacant unit pay or not?” becomes a more precise one: “what share of usage-based costs should a vacant unit carry?” That question has several reasonable answers. The reserve fund contribution normally stays in the fixed group, because future major repairs protect the value of every unit; we explain the reasoning behind that fund in building reserve funds and repairs.

Four Fair Ways to Calculate Charges for an Empty Unit

1. Full charge, unchanged: the simplest rule, suited to buildings that split charges equally or by floor area and whose costs are mostly fixed. The drawback is that the owner of the empty unit feels they are paying for other people’s consumption.
2. Fixed share only: the vacant unit pays its full share of fixed costs, and for usage-based costs its number of occupants counts as zero. This fits the “everyone pays for what they use” logic.
3. Minimum of one person: usage-based costs for the vacant unit are calculated as if it had one occupant. The reasoning is that empty units are still visited now and then, their utilities must keep working, and some cleaning and lighting still reaches them.
4. An approved percentage discount: the owners’ meeting approves a set percentage off the total charge for vacant units. It is easy to apply, but if the percentage is chosen without calculation it may fall below the unit’s real share of fixed costs, leaving the others to cover the shortfall.

None of these options is “the only right answer.” What matters is that one is chosen in writing and applied equally to every vacant unit, without exceptions.

Hypothetical Example: Charges for a Vacant Unit in an 8-Unit Building

Suppose an 8-unit building has one empty unit. Its monthly costs (entirely hypothetical figures, in any currency) are:

• Fixed costs: 16,000 (elevator, caretaker, insurance and lighting)
• Usage-based costs: 8,400 (shared water and cleaning)
• Total occupants in the 7 occupied units: 20 people

Fixed costs are split equally across the 8 units, so each unit pays 2,000. Now compare three options for the vacant unit and for a 4-person household:

As you can see, the options make a noticeable difference to the vacant unit but shift only a small amount for occupied units. Showing this table at the owners’ meeting usually moves the discussion from emotion to arithmetic. If you have not yet agreed on the basic split (equal, by area or by headcount), review how to calculate building charges first, then come back to the vacant-unit rule.

Who Decides, and How Should the Decision Be Recorded?

The rule for vacant units affects every owner’s pocket, so it belongs at the general meeting, not in a private conversation between the manager and one owner. To keep the resolution from becoming a dispute later, write these points into the minutes:

• Definition of vacant: when does a unit count as “vacant”? For example, when nobody has lived in it for a full calendar month.
• Notification: the owner must notify the manager in writing, in advance, when the unit becomes empty and when it is occupied again; notice after the month has ended is not accepted.
• Partial months: if a tenant moves in mid-month, is that month charged in full or pro rata?
• Special cases: a unit used as storage or an office, or one under renovation that uses the elevator and common areas more heavily, does not count as vacant.
• Review period: the rule is reviewed every year at the annual meeting.

Common Mistakes with Charges on Empty Units

• Giving one owner a verbal discount; as soon as another unit becomes empty, its owner asks for the same, and you can no longer say no.
• Reducing the charge to zero; the fixed cost of that unit lands on the neighbors.
• Changing the rule mid-year without a resolution; earlier and later statements no longer agree.
• Not recording the dates a unit became empty and occupied; a few months later nobody remembers exactly when it was vacant.

Recording Vacant-Unit Charges in Hamkhoneh Building Management Software

Once the rule is approved, the hard part is applying it consistently. In Hamkhoneh, P-Soft’s building management software for residential buildings in Iran (its interface is in Persian), each unit is recorded with details such as floor area, floor, parking and number of occupants, and charges are calculated with one of six methods: equal split, by floor area, by headcount, by parking, by floor, or a combination of these. Hamkhoneh does not discount vacant units automatically; the manager applies whatever rule the meeting approved by choosing the calculation method and keeping unit details (such as the number of occupants) up to date. In the headcount method, each unit’s share depends on its recorded number of occupants, so updating the vacant unit’s headcount in the same month it empties or fills again matters. Which method or combination best fits your building’s resolution is something you can go through with a specialist in a demo session.

A few other features help keep this transparent:

• The ownership and occupancy history of each unit is kept, so it is clear when a unit became vacant.
• Each unit’s statement is print-ready and can be saved as a PDF, so the owner can see exactly how their charge was calculated.
• In the Pro and Elite plans, the management dashboard shows the status of vacant units alongside collection trends, income and expenses.

Automatic charges, statements and unit files are available from the Start plan; for larger buildings that also need an analytical dashboard, the Pro plan is the better fit.

Frequently Asked Questions

Does a vacant unit have to pay building charges?

In most buildings, yes; it pays at least its share of fixed and maintenance costs. For the usage-based part, the owners’ meeting can approve a fair rule, subject to local law and your bylaws.

Who decides on a discount for empty units?

The owners’ general meeting or the building’s bylaws. The manager or board carries out that resolution and should not grant discounts case by case.

How should the charge for a vacant unit be calculated?

The most common approach is full fixed costs plus usage-based costs calculated with zero or one occupant. Whichever option is chosen must apply equally to all vacant units.

Is the reserve fund contribution also collected from vacant units?

Usually yes, because future major repairs protect that unit’s value too; the final decision still rests with the meeting.

Does a unit under renovation count as vacant?

Better not. Workers coming and going, and heavier use of the elevator and common areas during renovation, usually exceed what a normal occupied unit uses.
