A house construction agreement is the most important document you will sign with your builder. It turns promises made in meetings into written commitments. A clear agreement protects both you and the builder: everyone knows what will be built, to what standard, by when and for how much. A vague agreement is the root of most disputes, cost overruns and delays. This checklist covers the clauses every Bangalore homeowner should look for before signing.
1. Parties and property details
The agreement should clearly name the owner and the builder, with addresses and registration details, and describe the property: survey or site number, khata number, address and plot dimensions. These details should match your title documents.
2. Scope of work
Define exactly what the builder will do. Does the scope include architectural and structural design, plan approval support, construction, compound wall, sump, overhead tank, rainwater harvesting, septic tank and external works? Anything not listed tends to become an extra. At Golden Homes, our packages list every inclusion on the packages page.
3. Drawings as part of the contract
The approved architectural, structural, electrical and plumbing drawings should be attached or referenced. This makes the drawings the binding reference for what will be built.
4. Detailed specifications and brands
This is where many disputes start. The agreement should list brands and grades for steel, cement, blocks or bricks, concrete grade, waterproofing, flooring, tiles, doors, windows, paint, electrical wires and switches, plumbing pipes and sanitaryware. Words like "standard quality" or "equivalent" are not enough. Our materials guide explains what the grades mean.
5. Allowances for finishes
Where you will select items later, such as tiles or sanitaryware, the agreement should state the allowance per sq ft or per item and how upgrades will be charged.
6. Total price and what it includes
State the total contract value, the per sq ft rate, the built-up area calculation method and whether taxes are included. Check how balconies, headroom, staircase and sit-outs are counted.
7. Payment schedule
Payments should be linked to completed stages of work, not dates. A typical schedule might include an advance, then payments at foundation, plinth, each slab, brickwork, plastering, flooring and handover. Make sure the last payment is held until handover and snag fixing. If you are taking a loan, align the schedule with the loan disbursement stages.
8. Project timeline and milestones
The agreement should state the start date, completion date and key milestones, along with reasonable allowances for monsoon delays and approvals. Our guide to construction stages and timelines shows what a realistic schedule looks like.
9. Delay clause
What happens if the builder is late? Look for a clear delay compensation clause, and a matching clause on owner-caused delays such as late payments or late selections. Balanced clauses are a sign of a professional builder.
10. Price escalation
Is the price fixed, or can it change if material prices rise? A fixed price protects you from market swings. If escalation is allowed, it should be limited, clearly defined and tied to published indices.
11. Change orders
Changes are normal, but each one should be recorded in writing with its cost and time impact before the work is done. This single clause prevents many disputes.
12. Quality checks and site access
The owner should have the right to visit the site and inspect work, and the agreement should describe the quality checks the builder will perform, such as cube tests for concrete. See our quality checks guide.
13. Warranty and defect liability
Look for a structural warranty and a defect liability period for finishes, plumbing, electricals and waterproofing, with a clear process for raising and fixing issues. Read about our warranty.
14. Insurance and safety
The builder should be responsible for site safety, labour compliance and, ideally, contractor's all-risk insurance during construction.
15. Termination and dispute resolution
Define when either party can end the contract, how completed work will be valued and how disputes will be resolved, such as by mediation or arbitration in Bangalore.

Who should sign, and how
The agreement should be signed by the property owner or owners named in the title documents and by an authorised signatory of the builder. If the property is jointly owned, all owners should sign, or one owner should hold a valid authorisation from the others. Each page should be initialled, and both parties should keep an original. Pay the stamp duty that applies to the agreement under Karnataka law, since an unstamped or under-stamped agreement can be difficult to enforce. Attach the drawings and specification schedule as annexures, and number them clearly so there is no confusion later about which version applies.
Keeping records during construction
Signing is only the beginning. Keep a project file with the agreement, every payment receipt, every signed change order, site visit notes and photographs of each stage. If your builder shares a project app or weekly updates, save them. These records help resolve questions quickly and are useful later when you apply for the occupancy certificate or sell the property.
Red flags to watch for
- Large advance payments before any work starts
- Specifications missing or vague
- No delay clause, or only clauses that protect the builder
- Pressure to sign quickly
- Reluctance to attach drawings
Final word
A good agreement does not mean you expect problems. It means everyone is clear from the start. Read it carefully, ask questions and take legal advice if needed.
