Maintenance Fees in Phuket Condos: CAM Fee Guide for Property Investors

Quick answer: Common Area Maintenance (CAM) keeps shared condo infrastructure running, security, cleaning, elevators, pools, gyms and corridor utilities. Phuket investor budgeting often lands at 40-80 THB per sqm per month. A 50 sqm unit at 60 THB/sqm/month costs 3,000 THB/month, about $90/month or ~$1,080/year at ~33 THB/USD, before management, OTA or tax effects.

What do CAM bands mean for budget vs premium buildings?

CAM is not a luxury label, it is mostly labor + electricity + water + chemicals + insurance + management payroll. A building with multiple pools, large gardens, 24-hour security, and high lobby standards burns more hours and kilowatt-hours than a lean low-rise development.

Building tier	CAM range (THB/sqm/month)	What you typically see
Budget / lean	40-50	Smaller pool, simpler grounds, tighter staffing
Mid-range	50-65	Pool + gym, standard security hours, decent lobby
Premium resort-style	70-100+	Multiple pools, extensive gardens, stronger concierge/security

Always request the current juristic budget: advertised CAM from launch years may not match today’s electricity and wage reality.

Red flag: CAM far below peers in the same sub-market, often signals deferred maintenance, arrears among owners, or a special assessment coming.

What does CAM usually include, and what stays on your bill?

Included in CAM (common)	Typically not included (unit)
Security and reception staffing	Your electricity bill (A/C-heavy)
Cleaning of common areas	Your water (unit meter)
Elevator maintenance contracts	Internet (often owner-contracted)
Pool/gym maintenance	Interior repairs
Common-area electricity/water	Owner contents insurance
Juristic office administration	Personal property tax filings

Some projects bundle building insurance for structure in CAM; others itemize. Verify rather than assume. Annual ownership context: Annual Ownership Costs Thailand.

How do you calculate annual CAM at different unit sizes?

Using 60 THB/sqm/month as a mid scenario:

Unit size	Monthly CAM (THB)	Annual CAM (THB)	Annual CAM (USD @ 33)
35 sqm	2,100	25,200	~$764
50 sqm	3,000	36,000	~$1,091
80 sqm	4,800	57,600	~$1,745

If CAM is 80 THB/sqm/month on 50 sqm, monthly is 4,000 THB ($121) and annual is 48,000 THB ($1,455). That swing alone can change net yield by ~0.4-0.6% on a $200,000 purchase, enough to matter when comparing two “similar” listings.

How does CAM impact net rental yield?

Start from gross yield: annual rent divided by purchase price. Then subtract CAM, management, OTA commissions, maintenance, and taxes to approach net.

Illustrative example (not a promise):

• Purchase price: $200,000
• Gross annual rent: $16,000 (8% gross yield)
• CAM (50 sqm @ 60 THB): ~$1,091/year (~0.55% of price)

CAM alone is not the biggest line, management and distribution often dominate, but CAM is structurally persistent: you pay it in low seasons when revenue dips.

Cost line	Illustrative % of price (annual)
CAM	0.5-0.8% typical for many 50 sqm units
Management	3-7% of price (depends on % of revenue)
OTA commissions	2-6% of price (depends on channel mix)

Yield framework: Phuket Rental Yield Guide.

Why does CAM rise over time, and how should you model it?

Wages, chemicals, electricity tariffs, and insurance premiums trend up. Many experienced investors model 3-5% annual CAM growth for multi-year projections, conservative, but safer than flat assumptions.

Year	CAM/month (THB) starting 3,000	+3%/year
1	3,000	3,000
3	,	~3,273
5	,	~3,478

How do you compare two buildings with different CAM?

Assume two 50 sqm units both priced at $200,000 and both grossing $18,000/year (9% gross yield) before expenses, purely hypothetical.

• Building A: 50 THB/sqm/month → 30,000 THB/year (~$909/year)
• Building B: 75 THB/sqm/month → 45,000 THB/year (~$1,364/year)

The CAM gap is $455/year, about 0.23% of price annually. That alone rarely decides a deal, but if Building B also has higher occupancy due to location and guest demand, the net outcome can still win. CAM must be judged alongside revenue quality.

Who pays CAM in long-term vs short-term rentals?

Rental strategy	CAM handling
Short-term nightly	Owner pays CAM; revenue varies monthly
Long-term 12 months	Tenant may pay fixed rent; owner still settles CAM to building

In long-term tenant scenarios, owners sometimes negotiate gross rent inclusive of certain costs, but CAM is still charged to the owner by the juristic person. If you advertise “rent inclusive,” you are effectively bundling CAM into the tenant price, fine if your math works; dangerous if you underprice.

What questions should you ask the juristic office before buying?

1. Current CAM rate and last increase date
2. Arrears rate among owners (high arrears stress building finances)
3. Sinking fund balance and any planned special works
4. What insurance is included and what gaps remain for your unit
5. Special assessments in the last five years: amount and reason

Insider tip: Ask for the annual budget PDF, not a sales brochure line. Buildings with transparent governance publish meeting minutes and arrears statistics without drama.

What investor mistakes inflate perceived yield?

• Using launch CAM from a brochure dated three years ago
• Ignoring low-season occupancy while assuming high-season nightly rates year-round
• Forgetting that management + OTA often exceed CAM in gross terms for short-term rentals
• Comparing purchase $/sqm without normalizing CAM THB/sqm/month

Closing and tenure costs interact with CAM on leasehold stock; see Leasehold Fees Thailand and Hidden Costs Buying Property Thailand.

Why do unit electricity bills swing harder than CAM?

CAM includes common-area electricity, but your unit electricity is usually the largest variable operating cost for short-term rentals. In tropical climates, guests run air conditioning aggressively; owners who model $80/month may see $120-$180/month in peak heat months.

Cost	Typical control
CAM	Set by juristic budget
Unit electricity	Guest behavior + A/C efficiency + tariff

How do you compare CAM fairly across listings?

When comparing $/sqm purchase prices, also normalize CAM per sqm per month and sinking fund (if applicable). Two units with identical floor area can carry different CAM if one is in a tower with high elevator costs and the other is a low-rise with smaller common infrastructure.

Normalization	Why it helps
CAM THB/sqm/month	Strips out unit-size noise
Total annual CAM + sinking	Closer to “true carry”

What if you self-manage: does CAM still apply?

Some owners attempt direct booking strategies to reduce management percentages. Even with direct bookings, CAM remains and cleaning/laundry still cost money. The net benefit is often real, but not automatic, model your time or your local coordinator’s fees as a line item.

Approach	Typical tradeoff
Full-service operator	Less time, higher % fee
Hybrid / direct	More time, lower % fee

For most investors, the winning move is not “minimize CAM at all costs,” but maximize stable net cash flow after all recurring building charges. Purchase roadmap: Buying Property Phuket Guide. Tax lines: Thailand Property Tax for Foreigners.

CAM is governance, not greed, increases are often driven by real input cost inflation. The investor task is to pick buildings where governance is transparent: budgets published, meetings held, arrears controlled, and maintenance proactive.

How do sinking fund and special assessments relate to CAM?

CAM funds day-to-day operations. Sinking fund (reserve) funds irregular capital, roof, facade, elevator overhaul, pool retiling. They are separate line items; confusing them understates true carry.

Fund type	Purpose	Typical trigger
CAM monthly	Operations	Every month
Sinking (initial)	Opening reserve	At transfer
Special assessment	Emergency capex	When reserve insufficient

A building with low CAM but empty sinking fund and aging elevators is a future special assessment candidate, sometimes 100,000-500,000 THB per unit on older towers.

What does a full net-yield walk-through look like with CAM included?

Illustrative 50 sqm unit, $180,000 purchase:

Line	Annual USD	% of price
Gross rent	$14,400	8.0% gross
Management (18%)	−$2,592
OTA (15%)	−$2,160
CAM (55 THB/sqm)	−$998	0.55%
Utilities (owner-paid)	−$1,440
Insurance + minor repairs	−$600
Net before tax	~$6,610	~3.7% net

CAM is only ~15% of total operating drag here, but it is the line you cannot negotiate away in low season. That is why CAM-normalization belongs in every Phuket Rental Yield Guide comparison.

How do special assessments appear in practice?

Trigger	Example cost	Warning sign
Facade remediation	200-400 THB/sqm one-time	Visible concrete spalling
Pool resurfacing	Building-wide vote	Patch repairs repeating
Elevator modernization	High six figures total	Frequent breakdowns
Waterproofing failure	Legal disputes + capex	Mold complaints in multiple units

Due diligence: Ask for last 3 years of juristic meeting minutes and any pending votes before you sign.

What seasonal cash-flow table should investors keep?

Month type	Revenue	CAM
Peak (Nov-Mar)	Higher	Same
Shoulder	Medium	Same
Low (May-Oct)	Lower	Same

Keep 6 months CAM + average utilities in reserve, aligns with Budget Planning First-Time Phuket Buyers and Leasehold Fees Thailand guidance for all tenure types.

How do juristic person governance quality signals show up in CAM?

Signal	Healthy building	Unhealthy building
Budget publication	Annual summary to owners	”Trust us” verbal
Arrears rate	under 5% owners late	Chronic defaulters
Maintenance response	Ticket system + logs	Reactive firefighting
CAM increases	Explained line-by-line	Sudden jumps, no meeting

Insider tip: Attend one annual general meeting (or read minutes) before you buy, you are buying into a small democracy with shared bills, not only a view.

What CAM mistakes show up in broker yield sheets?

Brokers sometimes quote launch CAM from 2019 brochures, omit sinking fund, or assume zero vacancy while using peak ADR. Rebuild net yield with:

1. Current CAM from juristic email, not PDF
2. +3%/year CAM growth for years 2-5
3. 6-month vacancy or low-season haircut
4. Management + OTA as % of gross, not flat

A 0.5% CAM error on a $250K unit is $1,250/year, small alone, large compounded over hold period.

How does CAM interact with building age?

Building age	CAM trend	Investor note
0-3 years	Stable launch rate	Verify post-warranty repairs
4-10 years	Gradual rise	Elevator/pool capex approaching
10+ years	Higher unless refurbished	Special assessment risk

Older well-maintained buildings can outperform new towers with underfunded reserves, age alone does not predict CAM pain; governance does.

Bottom line: CAM is the non-negotiable operating tax of condo ownership, paid in baht, every month, in rain season and in boom season alike. When two listings look identical on price and view, the building with transparent CAM governance is often the better investment, even at 15 THB/sqm more per month. Normalize THB/sqm/month, read the juristic budget, model 3-5% growth, and keep six months liquid. Buildings with honest governance and healthy reserves are worth higher CAM; buildings with cheap CAM and empty reserves are often the expensive choice disguised as a bargain.

Before you buy, email the juristic office three questions: current CAM rate, last increase date, and sinking fund balance. Answers in writing beat brochure footnotes every time. Tie CAM into your wider cost map via Phuket Property Taxes & Fees Complete Guide and Hidden Costs Buying Property Thailand. Investors who normalize CAM per sqm across every shortlist stop chasing misleading headline yields. Add CAM growth and sinking fund to every net-yield model you trust, skipping them is how brochure yields beat bank balances. Treat CAM like rent you pay to the building, because that is exactly what it is. Buildings that fund maintenance properly are assets; buildings that defer it are liabilities with a view. Pick governance, not just granite lobby photos. The juristic office is your silent partner in every condo investment, choose it wisely. When CAM looks too good to be true, it usually is. Verify current CAM rates in writing today before you reserve any condo unit in the building.

Frequently Asked Questions

What are typical Phuket condo CAM fees? +

Many buildings fall roughly in the 40-80 THB per square meter per month range, with premium resort-style projects higher. Always confirm the current rate from the juristic office.

Does CAM include my electricity? +

Usually not for your private unit. CAM covers common-area electricity; your unit meter is typically billed separately.

How do CAM fees affect rental yield? +

CAM reduces net yield because it is a fixed operating cost. Investors should model CAM growth over time, not only year-one rates.

Why do two similar condos have different CAM? +

Amenities, staffing levels, energy use, maintenance standards, and reserve policies differ. A cheaper CAM is not better if it signals underfunded maintenance.

Can CAM be negotiated? +

You generally cannot negotiate CAM personally,it is set for the building. You choose projects with sustainable fee structures and finances.
