A condominium building is made up of common areas and private units. Residents are generally responsible for cleaning their own units, but who is supposed to clean the common areas? This article explains the difference between a condominium's common areas and its private units, and why cleaning the common areas actually matters. We also cover how to choose between cleaning the building yourself and hiring a professional cleaning company, along with what to look for when selecting a vendor. If you have just started operating a rental condominium building, this is essential reading.
What Are a Condominium's Common Areas? How Do They Differ from Private Units?
The common areas are the parts of the building that all residents share. Anything that is not a private unit (the living space itself) counts as a common area. Readers used to the American condo association model or the British leasehold block will recognize the basic split immediately, even though the Japanese terminology divides the shared space into finer categories than most English-speaking condo bylaws bother with.
Exclusive-Use Common Areas
These are common areas that an individual resident is allowed to use exclusively. Examples include the outside of the entrance door, balconies and verandas, any private garden attached to a unit, fire alarms, and the outer surface of window frames and glass. Because these are legally still shared property, a resident cannot replace or renovate them without authorization, even though only that resident actually uses them day to day. This is a subtler distinction than most American condo declarations draw; where a US homeowners association typically treats a balcony as either "limited common element" or simply part of the unit, Japanese practice keeps the exterior surfaces under building-wide control no matter how personal the space feels.
Shared Areas
These are the areas that all residents use together, such as the entrance lobby, elevators, stairwells, corridors, the garbage collection area, and parcel lockers. This is the closest match to what an American reader would simply call "common areas" in a condo association, or what a UK reader would call the "communal parts" of a block of flats.
How This Differs from Private Units
A private unit is an individual's living space, covering the inside surfaces of the ceiling, walls, and floor. As a rule of thumb, if a surface does not face outward toward the rest of the building or the outside world, it can safely be treated as part of the private unit.
Why Does a Condominium Need to Clean Its Common Areas?
Cleaning the common areas directly improves resident satisfaction, protects the building's asset value, and extends the building's usable life. It is not an optional extra in condominium management; it is one of the fundamentals.
It Improves Resident Satisfaction and Leaves a Good Impression at Viewings
A well-kept entrance and hallway create a favorable impression even in an older building. Insufficient cleaning, by contrast, tends to push up the risk of move-outs and vacancies. In competitive urban rental markets, whether in Tokyo, New York, or London, a scuffed, dusty lobby is one of the fastest ways to lose a prospective tenant before they even see the unit itself.
It Raises the Building's Asset Value
Proper cleaning raises the value of the building as an asset. If the building is ever sold, a higher asset value also makes it easier to sell at a strong price. This logic holds in any market: appraisers and buyers everywhere read visible upkeep as a proxy for how well the rest of the building, including the parts they cannot inspect, has been maintained.
It Extends the Building's Lifespan
Routine cleaning and patrols make it possible to catch defects early, which in turn allows repairs to be handled at an early stage, ultimately extending the life of the building. A property manager who is walking the halls every day is also the person most likely to notice a leak, a crack, or a failing fixture before it becomes an expensive structural problem.
What Types of Common-Area Cleaning Exist, and How Often Should Each Be Done?
Cleaning is generally divided into four categories: daily cleaning, patrol cleaning, periodic cleaning, and special cleaning. Use whichever mix suits the size and condition of the building.
Daily Cleaning
Sweeping, wiping, and picking up litter are ideally done several times a week. Sweeping and mopping the entrance every day, with the emergency stairwell cleaned roughly once a month, is a reasonable baseline.
Patrol Cleaning
This covers the same tasks as daily cleaning, but at a reduced frequency, and is generally used for smaller buildings. It is typically carried out anywhere from a few times a week to a few times a month.
Periodic Cleaning
This uses machinery such as high-pressure washers and floor polishers to remove stubborn grime from floors and walls. Once or twice a month is the usual benchmark, and this work is generally outsourced to a specialist company.
Special Cleaning
This is more specialized work, such as flushing drainpipes or cleaning hard-to-reach high areas. Once or twice a year is the usual benchmark, and hiring a dedicated house-cleaning specialist is recommended.
Should You Clean the Building Yourself, or Hire a Professional Company?
If keeping costs down is the priority, self-cleaning makes sense; if quality and time efficiency matter more, a professional cleaning company is the better choice. Let's compare the advantages and disadvantages of each.
Advantages of Self-Cleaning
- No cleaning expenses to pay
- Gives you a chance to talk with residents directly
- Lets you check the building's condition with your own eyes
Disadvantages of Self-Cleaning
- It takes considerable time
- A heavy burden if you also have a day job
- You cannot perform cleaning that requires specialized machinery or chemicals
Advantages of Professional Cleaning
- Reduces the time burden on the owner
- Delivers a high-quality finish from trained professionals
- An outside party is more likely to notice defects objectively
Disadvantages of Professional Cleaning
The main drawback is cost. Weigh the impact on management fees and, where it makes sense, split the work: handle daily cleaning yourself and outsource periodic and special cleaning, building an efficient management setup. Owners in the United States and the United Kingdom face essentially the same tradeoff, weighing a superintendent's or caretaker's in-house labor against a contracted cleaning service, and the calculation usually comes down to the same variables: building size, owner time, and how much quality control matters to prospective tenants.
What Should You Look for When Choosing a Condominium Cleaning Company?
Comparing quotes, the scope of work covered, consideration shown to residents, post-cleaning reporting, and a track record of experience are the five key things to check when selecting a vendor.
- Quoted price: Get quotes from several companies and confirm that the price matches the scope of service. It is best to have the company visit the building in person before quoting.
- Scope of work: Some companies handle cleaning only, while others also manage broader building maintenance or can arrange house cleaning after a tenant moves out.
- Consideration for residents: Because cleaning staff frequently interact with residents in common areas, choose a company whose staff behave courteously.
- Post-cleaning reporting: A company that reports back in detail on the work performed and anything noticed along the way is reassuring to work with.
- Track record: Check the company's website and reviews to confirm a solid history of past work.
What Checkpoints Reveal How Good a Cleaning Company Really Is?
Checking five specific spots, the grooves of the automatic doors, the elevator mats, the garbage bins themselves, the parking area, and the emergency stairwell, tells you a great deal about a company's true skill level.
- Automatic doors: Has dust and debris been cleared from the grooves, not just the glass surface?
- Elevator: Has the company noticed the mat wearing out and addressed it?
- Garbage bins: Is the grime on the bins themselves removed, not just the trash inside emptied?
- Parking and bicycle areas: Check immediately after cleaning to confirm there has been no corner-cutting.
- Emergency stairwell: Is this rarely used space still being cleaned on a regular schedule?

Frequently Asked Questions (FAQ)
Q. What does condominium common-area cleaning typically cost?
A house-cleaning company will typically charge around 8,400 to 15,000 yen per visit for floor cleaning and waxing. A "Silver Human Resource Center" (a Japanese public staffing organization that places retired and older workers in local part-time jobs, roughly comparable to a senior employment agency in the US or UK) can be engaged far more cheaply, at around 1,000 yen per visit.
Q. How often should daily cleaning be done?
Two to three times a week is ideal. Sweeping and mopping the entrance every day, in particular, helps raise resident satisfaction.
Q. What matters most when hiring a cleaning company?
It is important to get quotes from multiple companies, have them visit the building in person, and compare based on that. Also check their scope of service and their track record.
Q. What tools do you need for self-cleaning?
A broom, a mop, and cleaning cloths are the basics. It also helps to keep a large and a small cleaning brush, a paint scraper, a screwdriver and tweezers, disposable chopsticks (useful for reaching into tight corners and grooves), and a microfiber cloth on hand.
