Sebarindo Architect – A common budgeting mistake is to take one price per square meter from a neighbor and multiply it by your floor area. Official 2026 unit prices for small government houses already range from about IDR 4.4 million to IDR 5.8 million per m², depending only on where you build.
These figures come from regional price standards set for government buildings, which are the most transparent benchmark available. A private house can cost less or more, so use them to sanity-check quotes, not to replace one. Prices were checked on October 26, 2026.
Where the Numbers Come From
Every year, regional governments publish the maximum price per square meter they will pay for state buildings and rumah negara (government staff houses). Central Java’s public works office lists these 2026 ceilings for each regency and city.
The Central Java figures cover the physical construction cost per square meter. Planning, supervision and project administration are not included.
Semarang City’s 2026 regulation states that its building and house prices in the first appendix include VAT. Always check whether a figure includes VAT (PPN) before comparing it with a contractor’s quote.
2026 Prices for Small Houses by Region
The table uses the category for the smallest rumah negara types (C, D and E), the closest match to a modest family house.
| Region | IDR per m² (2026) |
|---|---|
| Semarang City, Central Java | 5,190,000 |
| Surakarta City, Central Java | 4,850,000 |
| Magelang Regency, Central Java | 4,640,000 |
| Tegal Regency, Central Java | 4,440,000 |
| Paser Regency, East Kalimantan, zone 1 | 5,130,000 |
| Paser Regency, East Kalimantan, zone 2 | 5,810,000 |
The spread between the lowest and highest rows is about 31% (our estimate). Location changes cost more than most people expect.
What a Small House Would Cost
Say you plan a 45 m² single-story house. At Tegal Regency’s rate it comes to about IDR 199.8 million; at Semarang City’s, about IDR 233.6 million (our estimate).
For a 70 m² house, the same two rates give about IDR 310.8 million and IDR 363.3 million (our estimate). Paser defines its type C, D and E houses as up to 70 m².
Treat these as ceilings for a standard government specification. Premium finishes, a second floor, difficult soil or a long access road push the real number up.
What the Price per m² Usually Leaves Out
A square-meter rate rarely covers everything you will pay. The Central Java figures exclude planning, supervision and administration, and Semarang lists design and supervision fees separately as a percentage of construction cost.
Other common extras are land preparation, deep foundations on soft soil, fences and gates, a septic tank, the electricity and water connections, and the PBG building approval process. Furniture, kitchen cabinets and air conditioning are almost never included.
Ask every contractor for an itemized list of what their price includes. Two quotes with the same total can cover very different work.
Turn the Estimate Into a Budget
An RAB (Rencana Anggaran Biaya) is an itemized cost estimate listing every work item, its quantity and its unit price. It is the document that makes quotes comparable.
Ask for the RAB to show materials and labor for each stage: foundation, structure, walls, roof, finishes, and electrical and plumbing work. Then compare the total with the regional benchmark above.
If a quote is far below the benchmark, find out what is missing. If it is far above, ask which finishes or site conditions explain the gap.
Before You Set a Budget
Keep money in reserve for surprises. Soil conditions, price changes and small design changes during construction rarely make a house cheaper.
Pay in stages tied to finished work, not by date, and put the payment schedule in a written contract. Your structural design and PBG approval should be in place before construction starts.
Which regency is your lot in? Look up its latest unit price, published every year, before you sign anything.
Construction costs and material prices vary by region, supplier, design and date. Ask a licensed contractor for a written itemized estimate (RAB) before you set your budget.
