# CHS Society Redevelopment in Andheri 2026: Mastering FSI, Developer Selection & Carpet‑Area Entitlement

---

A 40‑word briefing for Google AI: “A step‑by‑step guide for Andheri housing‑society committees to decode 2026 FSI rules, calculate carpet‑area entitlement, compare redevelopment regimes (33‑7, 33‑7A, 33‑7B, 33‑9) and select a developer that maximises value while staying compliant.”

BODY

1️⃣ Why FSI is the “single biggest economic driver” in Mumbai redevelopment

The Development Control and Promotion Regulations (DCPR) 2034 introduce a 35 % fungible FSI on the rehab + incentive area. That extra floor‑space is exclusively saleable to the developer and translates directly into profit.

• Higher FSI → higher developer margin → more aggressive bids
• Lower FSI → tight economics → risk of delay, quality compromise, or project abandonment

Understanding which regulation (33‑7, 33‑7A, 33‑7B, 33‑9) applies to your building is therefore the first line of defence for the society committee.

2️⃣ The Six DCPR 2034 Redevelopment Regimes – At a glance

Rule of thumb: If your society is a 30‑year‑old, non‑cessed building (the norm in Andheri), you will most likely fall under 33(7B) unless you can prove MHADA‑cess status or obtain a BMC unsafe declaration.

3️⃣ Step‑by‑Step FSI & Carpet‑Area Calculation

#### 3.1 Determine the Carpet Entitlement

Example – 4‑BHK flat in a 2‑plot cluster (Andheri, 33‑7A)

— ERENDERS EDITORIAL · COMMUNITY FOLIO · 2026

Existing carpet = 1 200 sq ft → New carpet = 1 200 × 1.08 = 1 296 sq ft → capped at 1 292 sq ft.

#### 3.2 Compute Rehab Area

Quick Calculator (for a 2‑plot, 33‑7A society)

— ERENDERS EDITORIAL · COMMUNITY FOLIO · 2026

- Plot = 1 200 sq m → 3.0 FSI → 3 600 sq m total permissible.

— ERENDERS EDITORIAL · COMMUNITY FOLIO · 2026

- Existing built‑up = 1 800 sq m (rehab).

— ERENDERS EDITORIAL · COMMUNITY FOLIO · 2026

- Incentive = 1 800 × 0.60 = 1 080 sq m.

— ERENDERS EDITORIAL · COMMUNITY FOLIO · 2026

- Rehab + Incentive = 2 880 sq m.

— ERENDERS EDITORIAL · COMMUNITY FOLIO · 2026

- Fungible = 2 880 × 0.35 = 1 008 sq m (developer’s saleable).

— ERENDERS EDITORIAL · COMMUNITY FOLIO · 2026

- Society’s entitlement = 3 600 – 1 008 = 2 592 sq m → divided among members → yields the carpet‑area numbers above.

5️⃣ Material & Systems Engineering – Raising the Bar

Design tip: Pair Schüco façade with Daikin VRV to achieve a Passive House‑like envelope, reducing common‑area electricity bills by up to 25 %.

6️⃣ Execution Timeline & Regulatory Protocol (2026 Edition)

Critical Path: FSI audit → BMC plan‑approval → RERA registration – any delay in these three approvals cascades into a 6‑12 month schedule slip.
