Moving into a condo in Bangkok is exciting, but if you don't plan the first 30 days right, you'll spend half that time running around chasing paperwork, waiting for the internet guy who never shows up, or fighting with utility companies that seem to operate on their own timeline. I've done this move myself, watched friends stumble through it, and seen expats throw their hands up in frustration during week two. The difference between a smooth handoff and absolute chaos usually comes down to what you do in those first four weeks.

The good news? Moving into a Bangkok condo is actually manageable if you know what to prioritize and in what order. This guide walks you through exactly what you need to do, when to do it, and why it matters. Let's break down your first 30 days so you can actually enjoy your new place instead of stress about whether the electricity is in your name yet.

Week One: Secure Your Legal Status and Verify What You're Getting

Before you unpack a single box, grab the Tenancy Agreement from your landlord or property manager and read it carefully. Yes, really read it. Look for the move-in date, lease duration, how much your deposit is, and what happens if you break the lease early. Many landlords in areas like Thonglor, Phetchaburi, and Asoke keep deposits between 1.5 to 2 months of rent, and you need to know exactly what damages or deductions they might claim.

Take photos and video of the entire unit. Every wall, every appliance, every scratch. Walk through with your landlord or agent and document the condition together. Send those photos to your landlord in writing (email works fine). This protects you both when you move out and prevents disputes over wear and tear. A friend renting in Sukhumvit learned this the hard way and lost 10,000 THB in deposit over alleged damage he didn't cause.

Check your legal residency status. Depending on whether you're Thai, a long-term expat, or here on a tourist visa, you may need to register your lease with local authorities. The Tenancy Act requires landlords to register agreements valued over 20,000 THB per year, though enforcement varies by neighborhood. If you're on a Non-Immigrant Visa or planning to stay long-term, ask your landlord or property manager which documents you'll need for immigration purposes.

Inspect all utilities and appliances. Test the air conditioning, hot water, stove, washing machine, and anything else included with the unit. Document any issues now, not later. Request a handover report signed by both you and your landlord listing what's working and what isn't. This becomes crucial when you move out.

Week One to Two: Set Up Electricity, Water, and Internet

Electricity in Bangkok is managed by the Metropolitan Electricity Authority, or MEA. You need to get the account transferred to your name or, if starting fresh, register a new account. Most condos handle this for you as part of the move-in process, but confirm with the property office. You'll need your ID, passport copy, and tenancy agreement. The MEA typically charges a small deposit (usually 500 to 2,000 THB) depending on your unit size and expected usage.

Water is similar. In most Bangkok condos, especially in central areas like Rama IV, Phetchaburi, and Sukhumvit, the condo itself manages water supply and charges residents through a shared metering system. Your monthly water bill usually shows up on your condo fee invoice. Ask your property office how much residents typically pay per unit, what's included, and whether there are any separate water meter readings you're responsible for.

Internet and phone are where delays happen. The big providers are AIS, TrueMove, and 3BB. Do not wait until week three to arrange this. Call or visit a provider's shop in your area the moment you know your move-in date. Three to five business days is the typical installation window, but Bangkok's installation teams can get backed up. Book immediately. Expect to pay a one-time setup fee of 500 to 2,000 THB and monthly bills between 600 and 1,500 THB depending on your speed and package. If you're moving to a building with existing fiber infrastructure (which most modern condos have), installation is faster.

Set up a Thai bank account if you don't have one already. Most landlords and condo offices prefer to process payments via bank transfer rather than cash. Visit a local Bangkok Bank, Kasikornbank, or Siam Commercial Bank branch near your new condo. You'll need your passport, proof of residence (your tenancy agreement works), and possibly a work permit if you're employed. The process takes about 20 to 30 minutes.

Week Two: Handle Condo Fees and Building Access

Condo common area fees cover maintenance, security, water, and shared utilities. This is separate from your electricity bill. Fees typically range from 20 to 60 THB per square meter per month depending on your building and location. A 50 square meter unit in a mid-range condo near Ploenchit or Ratchadamri might run 1,500 to 3,000 THB monthly in fees. Ask your property office for an itemized breakdown and ask whether you pay this monthly, quarterly, or annually.

Register your contact information with the building management. Provide your Thai phone number, email, and passport details. This is essential for building announcements, maintenance notifications, and emergency contact purposes. Many modern buildings like those near BTS Thonglor or MRT Sukhumvit have apps for residents to report maintenance issues and pay fees online.

Get your security access sorted. Request a door card, electronic key fob, or parking permit if you have a vehicle. Ask about parking rates if parking isn't included in your condo fee. A parking space in a building near BTS Asoke or Sukhumvit 55 usually costs 1,000 to 2,500 THB extra per month. Test everything before you leave the office to confirm it works.

Meet your neighbors and ask them about the building. Find out what the water pressure is like during peak hours, whether there are any planned maintenance shutdowns, and what the internet speeds are actually like. Ask about the nearest hospital, convenience store, and which motorcycle taxi drivers at the nearby BTS station are reliable. These conversations save you time later.

Week Two to Three: Register with Local Authorities and Immigration

Thailand requires all residents, Thai and foreign, to register with the local subdistrict office (called a "tambon office") within 24 hours of moving to a new address. In practice, nobody does this within 24 hours, but you should do it within the first two weeks. Bring your passport, a copy of your tenancy agreement, a TM 7 form (house registration form), and your landlord or an agent. The office near your soi will complete the registration, usually free or for a small fee under 100 THB. This registration matters because you'll need it for school enrollment, work permits, and various government transactions.

If you're a foreigner living in Bangkok long-term, you may need to complete 90-day reporting with immigration. If you're on a Non-Immigrant Visa, this is mandatory. Your first report is due 90 days from your last report, not from your move date. However, when you move, update your address with the Immigration Bureau. Bring your passport, a TM 28 form, and proof of your new address. The main office is on Soi 7 near Chaeng Wattana Road, but there are also smaller regional offices. Allow an hour or two for the process.

Register your tenancy agreement with the Land Department if your lease is long-term (over one year). This costs about 200 to 500 THB and provides legal protection for both you and your landlord. You can do this at any Land Department office, though the process requires both your signature and your landlord's. Many agents handle this automatically, so ask your property manager whether it's been done.

If you have dependents or family, register them at the local tambon office as well. This is required for school enrollment and becomes important if you ever need to access government healthcare or services.

Week Three: Address Healthcare, Schooling, and Essential Services

Register with a local doctor or clinic. Bangkok has excellent healthcare options. Bumrungrad International Hospital near BTS Ploenchit and Bangkok Hospital at various locations across the city offer world-class care. Many expats in Sukhumvit, Thonglor, and Rama IV also use smaller private clinics in their neighborhoods, which are cheaper and faster for routine visits. Get the contact details of a clinic near your condo and ask about their hours, pricing, and whether they accept your insurance.

If you have children, register them with schools now. Bangkok International School, Harrow International School, and other international schools have waiting lists. Even local Thai schools require documents like your child's birth certificate, vaccination records, and proof of residence. The tambon registration you completed in week two covers the residence proof. Do this early, especially if you're moving during the school year.

Set up health insurance or confirm your coverage. Many employers provide it, but if you're self-employed or freelance, you'll want to look into expat health plans. Cost runs 15,000 to 50,000 THB yearly depending on coverage. Check whether your current plan covers your new address and any specific healthcare providers you prefer.

Week Three to Four: Notify Relevant Parties of Your New Address

Update your address with your employer's HR department. They'll need this for tax purposes and salary payments. If you're self-employed or freelance, notify your clients or platforms of your new address for invoicing and contact purposes. In Thailand, if you earn income locally, you'll file annual tax returns, and your residential address matters for this.

If you run a business or have a Thai company, you may need to register your address with the Revenue Department for tax compliance. This varies depending on your business structure, but if you have Thai company signatory authority or ownership, keeping your registered address current matters legally.

Update your insurance companies, banks, and any services tied to your old address. Call your mobile providers to confirm your billing address is correct. Notify any subscription services you use. This prevents bills going to your old address and avoids payment issues later.

Most people moving into a Bangkok condo between Rama IV and Sukhumvit can expect to spend roughly 2,000 to 5,000 THB on setup costs during those first 30 days, excluding rent and condo fees. That covers MEA deposits, internet installation, bank account setup, and administrative fees. The real investment is your time, not your money.

The first 30 days in a new condo set the tone for your entire rental experience. Get the legal stuff handled early, confirm all utilities are working and in your name, and register yourself properly with local authorities. This prevents headaches when you eventually move out and keeps you compliant with Thai law. If you're moving to a popular area like Thonglor, Phetchaburi, or Sukhumvit, these steps matter even more because landlords there tend to be more particular about documentation.
