House Construction Agreement Checklist: 15 Clauses to Get in Writing Before You Build

Most disputes between homeowners and builders don't start with bad intentions. They start with something nobody wrote down — which tiles "standard quality" meant, who pays when cement prices jump, or what happens when the monsoon stops work for three weeks. A clear house construction agreement settles those questions before they turn into arguments. Here are the clauses worth getting in writing, and what each one should say.

Before You Start: What the Agreement Should Rest On

An agreement is only as good as the documents attached to it. Before drafting, make sure you have:

• The sanctioned building map and approval letter
• Structural drawings signed by a qualified structural engineer
• A specification schedule listing materials, grades and brands
• An itemised quote or bill of quantities (BOQ)

Attach all of these as annexures, and refer to them by name in the relevant clauses.

The 15 Clauses

1. Parties and Property Details

Full names and addresses of the owner and the contractor (including the contractor's firm or company details), plus a clear description of the property — plot or khasra number, village or mohalla, tehsil and district — matching your land records.

2. Scope of Work

Exactly what's included: site preparation, excavation, retaining walls, foundation, structure, masonry, plastering, flooring, plumbing, electrical work, doors and windows, painting, external works and boundary wall. Just as important, list what's excluded — interiors, furniture, landscaping, utility connection fees — so there's no ambiguity later.

3. Drawings and Specifications

State that the work will follow the attached sanctioned map, structural drawings and specification schedule, and that no structural change can be made without written approval from you and the structural engineer.

4. Materials: Grades and Brands

Name the cement type, the steel grade (for example Fe 500D), the concrete grade for each element, and the brands and ranges of tiles, sanitaryware, fittings, wiring, switches and paint. Any "equivalent" substitute should need your written approval.

5. Contract Price and Basis

Whether the price is a lump sum, a per sq ft rate on built-up area (and how that area will be measured), or an item rate against the BOQ. State whether GST is included.

6. Payment Schedule Linked to Milestones

Tie every payment to a completed, verifiable stage — foundation, plinth, each slab, masonry, plastering, flooring, finishing and handover — never to calendar dates. Avoid paying a large share upfront; a modest mobilisation advance is normal.

7. Retention Money

A small percentage of each bill — often around 5% — held back and released after the defect liability period, once any defects have been fixed. It gives the contractor a reason to come back.

8. Timeline and Milestones

A start date, a completion date and intermediate milestones. In the hills, be realistic about the monsoon — our construction timeline guide covers what's achievable.

9. Delay Penalties and Force Majeure

A reasonable penalty for delays the contractor causes, and a clear definition of events outside anyone's control — extreme weather, landslides, road closures, government orders. In this region those events are real, so define them rather than leaving them to argument.

10. Price Escalation

Say whether the price is fixed, or whether major material price changes (such as cement and steel) can be passed on — and if so, above what threshold, with what proof and up to what cap. A fixed price is simplest; a clearly limited escalation clause can be fairer on longer projects.

11. Variations and Extra Work

Any change you request should be priced and approved in writing before the work is done. Attach a rate list for common extra items so there's a reference point.

12. Approvals and Compliance

Who is responsible for obtaining the building approval, arranging any inspections, and making sure construction stays within the sanctioned map. Deviations can cause problems years later — see why house plans get rejected in Nainital.

13. Site Safety, Labour and Insurance

Responsibility for worker safety, compliance with labour laws, any applicable labour-welfare cess, and insurance for accidents and for damage to neighbouring property.

14. Defect Liability Period

A period after handover — commonly 12 months — during which the contractor must fix defects in their workmanship at no cost. Specify any longer guarantees separately, such as for waterproofing.

15. Termination and Dispute Resolution

How either side can end the contract (notice period, settlement for work done, handing back the site), and how disagreements will be resolved — typically discussion first, then mediation or arbitration, with a named location.

Handover: What You Should Receive

Add a short handover clause listing what you'll receive on completion:

• As-built drawings, including plumbing and electrical layouts
• Warranty cards and invoices for fittings and equipment
• Details of the waterproofing system used, and any guarantee
• Keys, meter details, and a snag list signed off by both parties
• A final account statement settling all payments and retention

Signing the Agreement

Execute the agreement on stamp paper of the value required under Uttarakhand's stamp law, signed by both parties in front of witnesses, and keep a signed copy of every annexure. For a significant project, a short review by a property lawyer is money well spent.

Red Flags in a Contractor's Draft

• No specification schedule, or vague terms like "good quality" and "standard brand"
• A large upfront payment before any work begins
• Payments tied to dates rather than completed stages
• No mention of defects, retention or delay penalties
• Reluctance to put verbal promises in writing

Frequently Asked Questions

Is a written construction agreement necessary for a private house?

There's no single mandatory format for a private house, but a written, signed agreement is the only practical way to hold anyone to what was promised. Verbal agreements are very hard to prove.

Does a construction agreement need to be registered?

A construction contract generally isn't required to be registered the way a property sale deed is, but it should be properly stamped. Ask a lawyer about the stamp duty that applies to your agreement.

How much retention money is normal?

Around 5% of each bill is common, released at the end of the defect liability period.

What is a defect liability period?

A period after handover — often 12 months — during which the contractor must repair defects in their work free of charge.
