A renovation can lift rent and resale value, or create problems with the society and future buyers. What needs permission, what doesn't, and how to keep the paperwork clean.

Many owners renovate before renting or selling. Most work is routine. The trouble starts with structural changes, or with work done without telling the society.
| Work | Usually needs |
|---|---|
| Painting, new fittings, modular kitchen, wardrobes | Written intimation to the society, and following its working hours and debris rules |
| Changing bathroom tiles and waterproofing | Society intimation. Done well, it prevents leaks below |
| Breaking non-load-bearing walls | Society permission and a structural engineer's opinion |
| Touching beams, columns or slabs | Not allowed without structural approval and civic permission. Avoid |
| Enclosing balconies or changing the facade | Society and municipal permission. Unauthorised changes can attract action |
A buyer's lawyer will ask about every wall you moved. Keep the permissions with the title papers.
Buyers, banks and lawyers check whether the flat matches the approved plan. Unauthorised changes such as enclosed balconies can complicate a loan or sale. See OC and approval risks.
Approve the scope, budget and contractor in writing before work starts, and ask for weekly photos. For flats we manage, the named manager supervises work, and you see updates in the TND app.
For cosmetic work, usually written intimation and following society rules. For structural changes, society permission and a structural engineer's opinion, plus civic approval where required.
Only with the required approvals. Unauthorised enclosures can attract civic action and complicate resale.
General information. Consult a structural engineer and your society before structural work.
