Home Renovation Cost Per Sq Ft in India (2026)

"How much per square foot to renovate?" is a harder question than "how much per square foot for interiors?", and the answers families hear vary wildly — ₹500 from one contractor, ₹3,000 from another, both for the same flat. Usually neither is wrong. They are pricing different scopes. One is quoting for paint, new lights and a few wardrobe shutters; the other is quoting for taking the home back to bare walls and slab and rebuilding its wiring, bathrooms, floors and joinery. Until the scope is fixed, a per-square-foot renovation rate means very little.

Renovation also carries costs that new interiors do not. Old tiles must be broken out and carried down in bags; wiring installed twenty years ago for two fans and a fridge now has to carry air-conditioners, geysers and induction hobs; bathrooms that leak into the flat below must be rebuilt from the slab; and the society wants deposits, permissions and working-hour limits. On top of all that sits uncertainty: nobody knows exactly what is behind an old wall until it is opened.

This guide sets out indicative October 2026 renovation rates for Indian homes by scope and specification, then builds them into budgets for a 1BHK, 2BHK, 3BHK and a bungalow, with a full line-item estimate for a 2BHK. The figures are consistent with this site's interior cost guides and its comparison of renovation and new interiors, and they are written for tier-2 cities such as Surat, Ahmedabad, Pune or Indore; metros run higher. They exclude GST unless stated and should always be confirmed with local quotations.

Four scopes of renovation

Before any rate can be quoted, the scope must be named. In practice nearly every Indian renovation falls into one of four levels. A refresh changes what can be seen without touching services: paint, lights, curtains, hardware and a few loose items. A partial renovation rebuilds one or two systems or rooms — typically the kitchen and bathrooms — and keeps the rest. A full renovation takes the home back to the structure and rebuilds wiring, plumbing, bathrooms, floors and all joinery. A structural renovation adds repair, strengthening or extension of the structure itself, and cannot be priced until a structural engineer has inspected the building.

The full-renovation rates are built from two parts. The first is the interior itself — joinery, ceilings, lighting, paint — which costs about the same in a new flat and an old one: about ₹800–1,100 per sq ft of carpet area basic, ₹1,250–1,800 mid-range and ₹2,200–3,350 premium, matching the Surat bands for 1BHK, 2BHK and 3BHK homes used across this site. The second is the renovation layer: strip-out, debris removal, rewiring, bathrooms rebuilt from the slab, floors removed and relaid, and repairs. This site's renovation comparison puts that layer at roughly ₹550–1,200 per sq ft. Fig. 1 shows the two parts stacked.

Renovation budgets by home size

Applying those two parts to typical Indian homes gives the budgets below for a full renovation. The interior figures are the Surat bands this site uses for new interiors: a 1BHK of 500 sq ft at ₹4–5.5 lakh basic, ₹6.25–9 lakh mid and ₹11–16.5 lakh premium; a 2BHK of 1,000 sq ft at ₹8–11 lakh, ₹13–18 lakh and ₹23 lakh or more; a 3BHK of 1,250 sq ft at ₹10–13.5 lakh, ₹15.5–22.5 lakh and ₹27–42 lakh; and a 3,000 sq ft bungalow, including loose furniture, at ₹24–33.5 lakh, ₹36–56 lakh and ₹64–103 lakh. The renovation layer is added at ₹550–800 per sq ft for basic work, the line-item figures for mid-range work, and ₹900–1,200 per sq ft for premium work.

Two cautions apply. First, these are full renovations; most families do less, and a partial renovation of the kitchen and bathrooms with a repaint usually costs a fraction of the full figure. Second, a bungalow carries items a flat does not — terrace waterproofing, external painting, compound walls, sumps and pumps, sometimes structural repair — which should be priced separately after inspection. A PU liquid membrane on a terrace runs about ₹70–150 per sq ft and exterior emulsion about ₹17–26 per sq ft of wall, as this site's waterproofing and cladding guides note.

A line-item estimate for a 1,000 sq ft 2BHK

A per-square-foot rate hides the decisions that drive it, so it is worth building a budget line by line. The example below is a twenty-year-old 2BHK of about 1,000 sq ft carpet area, renovated to a mid-range specification: modular kitchen and wardrobes in BWR plywood with laminate, gypsum ceilings in living and bedrooms, LED lighting, premium emulsion, two bathrooms rebuilt, vitrified flooring throughout and complete rewiring. The interior line uses the Surat 2BHK mid-range band; every renovation line uses the unit rates in this site's renovation, bathroom and tile-laying guides.

The bathrooms are the biggest renovation line, and the interior is still about two-thirds of the bill. That is why the most effective savings in a renovation usually come from the interior specification — fewer full-height units, simpler ceilings, laminate instead of veneer — rather than from cutting the renovation layer. Rewiring and waterproofing are the two lines that should never be cut: both are buried once the work is finished, and both are far more expensive to redo later than to do properly now.

Room-by-room costs for partial renovation

Many families renovate in stages: the kitchen this year, the bathrooms next year, the bedrooms when the children grow up. The table gives indicative October 2026 costs for the most common room-level jobs, drawn from this site's kitchen, bathroom, flooring, ceiling and painting guides. They can be added together to price a partial renovation.

A worked partial renovation for the same 2BHK: an L-shaped modular kitchen at ₹1.5–3 lakh with old platform removal, new dado tiles and kitchen plumbing points at about ₹50,000–1,05,000; two bathrooms at the standard ₹1.2–1.8 lakh each, or ₹2.4–3.6 lakh; and a repaint of about 3,500 sq ft of paintable wall and ceiling at ₹20–30 per sq ft, or ₹70,000–1,05,000. The total is about ₹5.1–8.7 lakh — roughly a quarter to a third of a full mid-range renovation.

Floors: overlay or strip?

Flooring is one of the largest decisions in a renovation because it decides whether the floor is broken out, which creates noise, dust, debris and a week or more of extra time. Where the old floor is sound — no hollow, cracked or lifting tiles over most of the area — new vitrified tiles can often be laid directly over it with a polymer-modified tile adhesive. That avoids removal costs and debris, but it raises the floor by roughly 12–16 mm, which affects doors, thresholds and the junction with bathrooms and balconies.

Hidden costs, contingency and GST

The figures above are the visible budget. Every renovation also carries costs that are easy to forget until they arrive. A contingency of about 10–15 per cent of the renovation layer, more for very old homes, covers what is found on opening walls and floors: corroded pipes, rotten door frames, an old beam that needs an engineer's attention, a bathroom slab that leaks more than expected. GST is commonly charged at 18 per cent on interior works contracts and should be confirmed in every quotation. Societies often collect a refundable deposit and charge for lift protection and common-area cleaning, and many limit working hours, which lengthens the programme.

Reading a renovation quotation

Two renovation quotations for the same flat are rarely comparable line by line, because contractors group items differently. Before comparing totals, ask each contractor to split the quote into the same headings: strip-out and debris; civil changes; electrical; plumbing; waterproofing; flooring; bathrooms; ceilings; joinery; paint; and exclusions. Check that the electrical line names the cable brand and size, the distribution board and the residual current protection; that waterproofing names the system and includes a pond test; that flooring states whether old tiles are removed or overlaid; and that bathrooms state whether they are a refresh, a standard redo or a full strip to the slab. A quote that is much lower than the others has usually left out one of these headings rather than found a cheaper way to do it. Finally, ask how variations will be priced — at the same unit rates as the quote, agreed in writing before the work is done — because some change is almost certain once walls and floors are opened.

How long a renovation takes

A full renovation takes longer than new interiors because work happens in sequence rather than in parallel: walls and floors must be opened, services rebuilt and tested, wet areas waterproofed and floors laid before joinery can be measured. This site's renovation comparison guide puts a full renovation at about 18–24 weeks on site after design, against about 10–16 weeks for new interiors. Fig. 4 shows a typical sequence.

How Indian homes have been renovated, and where it is going

For generations, Indian homes were maintained rather than renovated. Lime-washed walls were refreshed before festivals — the pre-Diwali clean and whitewash is still a household ritual in much of the country — floors of Kota stone, mosaic or IPS were polished or patched, and timber doors were re-oiled. Kitchens and bathrooms changed slowly because they were built in masonry and stone. The idea of stripping a home back to its structure and rebuilding everything inside it arrived with the apartment boom, when homes bought in the 1990s and 2000s began to reach twenty or thirty years of age with wiring, plumbing and bathrooms that no longer suited modern life.

Today renovation is a large and growing part of interior work in Indian cities, particularly in resale flats in established neighbourhoods, where location matters more than newness. The present-day pattern is clear: services are replaced wholesale rather than patched, bathrooms are rebuilt with proper waterproofing, floors are overlaid where possible to save time, and joinery is made in factories rather than on site. The future points towards drier, faster methods — prefabricated bathroom pods, raised access floors in some premium projects, surface-mounted or skirting-level wiring systems that can be changed without breaking walls, and modular joinery that can be dismantled and reused. All of these reduce the renovation layer that this article prices, which is the most expensive and disruptive part of the work.

For families in Surat and other Gujarat cities, two local factors matter. Humid monsoons mean that old bathrooms and external walls often hide damp, so waterproofing and plaster repair lines should be generous. And many older flats have low-voltage complaints and undersized wiring, so rewiring is rarely optional. Aaditya Interior's experience is that the families who budget the renovation layer honestly from the start finish closest to their original figure.

Rules for budgeting a home renovation

• Name the scope first — refresh, partial, full or structural — and get every quote for the same scope.
• Budget a full renovation as interior rate plus renovation layer: about ₹550–1,200 per sq ft on top of the interior.
• Never cut rewiring or waterproofing to save money; both are buried and costly to redo.
• Tap-test the old floor before deciding to overlay; overlay only a sound floor and plan for a 12–16 mm rise.
• Keep a 10–15 per cent contingency on the renovation layer, separate from upgrades.
• Ask whether quotes include GST, debris removal, society charges and loose furniture.
• Get a structural engineer to inspect before any wall, beam, column or slab is touched.
• Measure joinery only after floors and walls are final, and plan for about 18–24 weeks on site.

Frequently asked questions

What is the renovation cost per sq ft in India in 2026?

Indicatively, about ₹200–600 per sq ft for a cosmetic refresh, and about ₹1,350–1,900 basic, ₹1,800–3,000 mid-range and ₹3,100–4,500 or more premium per sq ft of carpet area for a full renovation including new interiors, in tier-2 cities. Metros run higher.

How much does it cost to renovate a 2BHK flat?

A full mid-range renovation of a 1,000 sq ft 2BHK costs about ₹18.5–30 lakh before loose furniture, appliances and GST. A partial renovation of the kitchen and both bathrooms with a repaint costs about ₹5.1–8.7 lakh, and a refresh about ₹2–6 lakh.

Is it cheaper to renovate or buy a new flat?

It depends on the price gap between the resale flat and a new one. A full renovation adds roughly ₹550–1,200 per sq ft over new interiors and about two months on site. If the resale flat is cheaper by more than that, in a better location, renovation can make sense; this site's renovation versus new interiors guide explains the calculation.

Can new tiles be laid over old tiles?

Yes, if the old floor is sound, level and well bonded. New tiles are laid with a polymer-modified adhesive, which raises the floor by about 12–16 mm, so doors may need undercutting and thresholds need detailing. If more than a few tiles sound hollow or are cracked, the floor should be removed and relaid.

How long does a full house renovation take?

For a typical flat, about 3–5 weeks of design and survey, then about 18–24 weeks on site for a full renovation. A refresh can take 2–4 weeks; a partial renovation of a kitchen and bathrooms about 6–10 weeks.
