Key takeaways
Never remove or cut load-bearing walls, columns, beams or slabs without a structural engineer and approvals.
Most societies require written permission, working hours and a deposit for renovation.
Enclosing balconies or changing the façade may breach building approvals.
Use a written contract with scope, cost, timeline and warranty, and check waterproofing carefully.

Renovation can transform a flat, but in a shared building your work affects neighbours and the structure. Plan it properly.

Structural safety

In many RCC buildings, columns, beams and slabs carry the load; some walls may also be structural in load-bearing or shear-wall buildings. Do not break, chase deeply into or drill large openings in structural elements. Get a structural engineer's written opinion for anything beyond cosmetic work.

Society rules

Written application and approval.
Working hours and no work on holidays.
Debris disposal arrangements.
Lift protection and usage rules.
Refundable damage deposit.
Contractor and worker IDs for security.

Waterproofing

Bathroom and balcony renovations often cause leaks into the flat below. Insist on proper waterproofing, a water-ponding test before tiling and a written warranty.

Contract with your contractor

Detailed scope and materials with brands.
Fixed price or rate schedule.
Payment milestones.
Timeline and delay penalties.
Warranty, especially for waterproofing and electrical work.
Who handles debris and permissions.

Fire safety

Do not block fire exits or remove fire-rated doors. See fire safety in high-rise apartments.

Rented flats

Tenants need the landlord's written consent for any changes.

Frequently asked questions

Do I need permission to renovate my flat?

Usually you need the society's permission, and structural or façade changes may also need approval from the authority.

Can I remove a wall in my apartment?

Only if a structural engineer confirms it is not load-bearing and required permissions are obtained.

Is balcony enclosure allowed?

It often breaches building approvals or society rules. Check with the society and the authority before doing it.

How do I prevent leaks after bathroom renovation?

Ensure proper waterproofing, a water-ponding test before tiling and a written warranty from the contractor.
