Moving to a pet-friendly apartment requires different preparation and considerations than a standard move. To help you and your beloved dog or cat start your new life comfortably, this guide brings together practical advice from real estate professionals covering everything from pre-move preparation to post-move rules and strategies for minimizing restoration costs at checkout.
Moving preparation hinges on the sequence of "what, when, and where to place." By understanding rental-specific constraints and correctly grasping priorities and budget allocation, you can achieve a comfortable living space while keeping initial costs down.

In recent years, as more people welcome pets as family members, demand for pet-friendly rental properties has steadily grown. According to research by the Ministry of Land, Infrastructure, Transport and Tourism, pet-friendly properties account for only about 15–20% of all rental housing, and the reality is that supply is not keeping up with demand.
Particularly in urban areas, singles and DINKs (dual-income, no kids couples) are increasingly living with pets, and many prospective tenants now make "pet-friendly" an absolute requirement from the start of their property search. On the other hand, landlords remain concerned about "increased restoration to original condition costs" and "problems from noise and odor," which has held back growth in the number of pet-friendly properties.
Given this situation, when you find a pet-friendly property, it is extremely important not only to be reassured by the fact that you can keep a pet, but to carefully verify the property conditions and contract terms in order to achieve a comfortable living situation long-term.
Even though a property is pet-friendly, the types of pets allowed vary greatly from property to property. While it's easy to misunderstand that "pet-friendly = all animals OK," in reality most properties have specific conditions in place.
The most commonly approved pets, but number, size, and breed are often restricted. For example, conditions such as "only one small dog" or "cats limited to one, indoor-only" are not uncommon. Large dogs (20 kg or heavier, for example) are prohibited in many properties due to noise and their impact on the apartment.
When selecting a property, it is important to check by providing information about your pet's expected weight and breed when fully grown. Even if introduced as a Chihuahua, mixed-breed dogs can end up significantly larger than expected at full size.
Small animals like hamsters and goldfish are often permitted even in "pets negotiable" properties, giving you relatively more options. However, birds (particularly parrots and large macaws) are prohibited in many properties due to noise concerns, and property management companies often hesitate to allow reptiles.
"Pets negotiable" and "pet-friendly" are different things. The former means permission may be granted depending on negotiation, but it does not guarantee you can keep a pet. It is essential to confirm directly with the property manager during a viewing and obtain written approval.
When entering into a pet-friendly rental contract, there are many more items to confirm than in a standard rental agreement. To prevent future problems, be sure to confirm and agree on the following points in writing.
The "special clauses" section of the rental agreement should clearly state the terms regarding pets. Main items to check are as follows:
Special clauses have legal binding force, so assuming "it's fine because permission was given orally" is dangerous. Make sure to document all agreements in writing.
In condominium-type properties, pet ownership may be prohibited under the management association's rules regardless of the landlord's approval. There have been actual cases where the landlord says "OK" but the management rules prohibit it, leading to problems after moving in. It is ideal to obtain and review a copy of the management rules in advance.
Pet-friendly properties tend to have higher initial costs compared to standard rentals. Understanding the typical costs for major expenses allows you to create an accurate financial plan.
While security deposits for standard rentals are typically 1–2 months' rent, pet-friendly properties often require 2–3 months' rent. This accounts for the risk of damage or soiling caused by pets and is applied to restoration to original condition costs upon move-out.
More properties are now requiring a "pet deposit" (separate from the security deposit) equal to 1–2 months' rent. Pet deposits are held as collateral for cleaning and deodorization costs upon move-out, and some are "non-refundable" or partially non-refundable. Be sure to confirm the refund conditions before signing the contract.
Key money may also be 0.5–1 month higher than normal, and some properties add a "pet care fee (approximately ¥3,000–¥10,000 per month)" to the monthly rent. Even if the advertised rent appears low, your actual monthly cost may be higher, so a comprehensive cost comparison is necessary.
Pet owners living in pet-friendly properties bear greater ethical and social responsibility than those in non-pet properties. Efforts to minimize impact on neighbors and future tenants are essential for maintaining a good living situation.
Excessive dog barking and cat night cries are major causes of neighbor disputes. Take proactive measures such as installing soundproof mats, attending training classes, and consulting a veterinarian if necessary. Demonstrating that you are taking steps when complaints arise helps maintain trust with the management company.
It is essential to promptly remove pet waste and perform regular ventilation and deodorization. In particular with cats, odor from marking (spraying) penetrates walls and flooring and is difficult to remove, so early intervention directly reduces costs at move-out.
Allowing pets to move without a leash in elevators or hallways and leaving pet waste creates serious disputes with other residents. Strict adherence to rules set out in the management agreement is a minimum obligation, and showing common sense consideration even in situations outside the rules is important.
Cost settlements at move-out in pet-friendly properties are more likely to cause problems than in standard rentals. It is important to understand the "Troubles and Guidelines Regarding Restoration to Original Condition" as defined by the Ministry of Land, Infrastructure, Transport and Tourism and conduct appropriate negotiations.
The guidelines indicate that "normal wear and tear" or "natural deterioration" from normal living should not be charged to tenants. However, scratches, bite marks, urine stains, and odor caused by pets are often judged as damage resulting from "tenant negligence or fault" and are likely to be charged as restoration to original condition costs.
Many pet-friendly properties have special clauses requiring tenants to bear deodorization and cleaning costs at move-out (such as tatami replacement and wallpaper replacement). Such a clause is considered valid if it meets three conditions: "① it is necessary and reasonable," "② the tenant is aware of it," and "③ the tenant's burden does not exceed general standards."
The best way to prevent unjust charges after move-out is to specifically confirm "what costs will be incurred at move-out" before moving in and obtain written estimates explaining the basis for the charges.
Recording the condition of the entire room, walls, and flooring with photos and videos immediately after moving in is highly effective. By retaining evidence of pre-existing damage or dirt, you can greatly reduce the risk of being charged for "pre-existing damage" at move-out.
At the move-out inspection, you have the right to request a checklist and itemized settlement statement, and to withhold your signature if you disagree with the contents. If you are unsatisfied with the security deposit refund amount, consider consulting the National Consumer Affairs Center or a lawyer.
Living in a pet-friendly rental becomes fulfilling only with proper knowledge and preparation. Careful confirmation before signing a contract and improved etiquette during occupancy help ensure a good living environment for you, your pet, and those around you for the long term.
