House building approvals and documents in India (2026)

Design IRL Editorial · Figures checked 7 November 2026 · For plot owners getting ready for building plan sanction · How we make our guides

Building a house in India usually means 2 to 4 months of approvals before you break ground, at about 1–3% of the project cost. Plan sanction takes 30–90 days on paper, and agricultural land first needs a land-use conversion of 30–120 days. Skipping approvals can cost you the house.

Start with clean title

Before any drawing, make sure the plot is legally yours and free of claims. The local authority will ask for these papers with your plan, and a bank will ask for them before a loan.

Title deed or sale deed.
Encumbrance certificate (EC), showing no loans or claims on the land.
Mutation or khata extract in your name.
Up-to-date property tax receipts.
In Tamil Nadu, also patta, chitta and adangal.

The approvals, in order

The exact list depends on your state and city, but most houses go through the same steps. Times and costs below are approximate. Add 20–30% to whatever timeline the portal promises.

From a cement-brand guide to approvals. Your local authority's fees may differ.

Overall, approvals usually come to about 1–3% of the project cost, or 2–5% where development charges apply. Some cement-brand estimates put plan sanction and approvals at ₹50,000 to ₹2 lakh for a typical house.

City	Rough approvals allowance for budgeting
Mumbai	about ₹35 per sq ft
Delhi, Gurugram, Noida, Pune, Chennai, Hyderabad	about ₹20 per sq ft
Bengaluru	about ₹20 per sq ft, or about ₹1 lakh minimum for G+1
Kolkata, Ahmedabad	about ₹20 per sq ft

Land-use conversion

If the plot is recorded as agricultural, it must be converted for residential use before a plan can be sanctioned. This is often the slowest step, at 30 to 120 days. Check the land records before you buy, not after. Conversion fees are usually about ₹10,000 to ₹50,000, but the waiting time matters more, because nothing else can move until it is done.

Building plan sanction and bye-laws

Your architect prepares the drawings to meet local building bye-laws, and usually handles the submission for you. These set how far the house sits from each boundary (setbacks), how much of the plot it can cover, and how much floor area you can build in total (FAR or FSI). The submission usually includes the architect's drawings, a structural stability certificate and a survey sketch.

Many cities now take applications through an online building permission portal. Ask your architect which system your local authority uses, and keep copies of every receipt and acknowledgement. Fees change from time to time. In Kerala, for example, permit fees were raised sharply in April 2023 and then cut by 50–60% from August 2024.

Commencement, completion and occupancy

Commencement certificate: some states need one before you start work on site. It takes about 15 to 45 days.
Completion certificate: confirms the house was built as sanctioned.
Occupancy certificate: confirms the house is fit to live in. Together these take about 30 to 60 days.
Some banks keep back a final part of a construction loan until the occupancy certificate is issued.

What happens if you skip approvals

The risk is real

Without a completion or occupancy certificate, water, power and sewer connections may be refused. Unapproved construction can face demolition.

Build the approvals time into your plan. Expect 2 to 4 months before you break ground, and keep the 10% contingency for fee changes and delays. Figures here vary by city, so check your local authority's current schedule and ask 2 to 3 architects how long sanction is taking in your area.

Common questions

Which approvals do I need before building a house in India?

Every house needs building plan sanction and utility NOCs for water, sewer and power. Agricultural land first needs a land-use conversion, some states need a commencement certificate before work starts, and a fire NOC or environmental clearance applies only above size thresholds. Completion and occupancy certificates come at the end.

How long does building plan sanction take?

Building plan sanction takes 30–90 days on paper, and often 2–4 months in practice, at roughly ₹20,000 to ₹1 lakh. Add 20–30% to whatever timeline the online portal promises.

What documents are needed for building plan approval?

The local authority asks for the title or sale deed, an encumbrance certificate, a mutation or khata extract in your name and up-to-date property tax receipts. In Tamil Nadu, patta, chitta and adangal are also needed. The submission usually includes the architect's drawings, a structural stability certificate and a survey sketch.

Can I build a house on agricultural land?

Agricultural land must be converted for residential use before a building plan can be sanctioned. Land-use conversion is often the slowest step, at 30–120 days, with fees of about ₹10,000–50,000, and nothing else can move until it is done.

How much do house building approvals cost?

Approvals usually come to about 1–3% of the project cost, or 2–5% where development charges apply. As rough budgeting allowances, Mumbai is about ₹35 per sq ft and Delhi, Pune, Chennai, Hyderabad, Kolkata and Ahmedabad about ₹20 per sq ft; Bengaluru is about ₹20 per sq ft, or a ₹1 lakh minimum for G+1.

What happens if I build a house without approvals?

Unapproved construction can face demolition. Without a completion or occupancy certificate, water, power and sewer connections may be refused, and some banks keep back the final part of a construction loan until the occupancy certificate is issued.
