Boarding House Cost Per Room in Sydney — 2026 Price Guide

How Much Does a Boarding House Cost Per Room in Sydney?

A new-build boarding house in Sydney costs $100,000–$180,000 per room in 2026, depending on location, room size, common area allocation, and fit-out specification. A typical 10–12 room boarding house on a 600–800 sqm site in Western Sydney has an all-in construction cost of $1.2M–$2.0M.

These per-room figures include all shared facilities (kitchen, laundry, common living area, bathrooms) and external works, allocated proportionally across rooms. They do not include land acquisition.

Buildana (Lic. 487805C) has built boarding houses across Fairfield, Liverpool, Cumberland, and Canterbury-Bankstown LGAs. We deliver fixed-price boarding house construction with every room designed for maximum rental yield under NSW Affordable Rental Housing SEPP provisions.

Per-Room Cost Breakdown (2026 Rawlinson-Adjusted)

Structural and Envelope (per room): $35,000–$50,000 • Foundation/slab allocation • Frame, external walls, roof • Windows and external doors • Waterproofing and insulation

Factors That Affect Per-Room Cost

Several factors push per-room costs up or down:

Room configuration: Ensuite rooms cost $10,000–$18,000 more per room than shared-bathroom configurations. However, ensuite boarding houses achieve 15–25% higher weekly rents — the investment typically pays for itself within 2–3 years.

Building storeys: Two-storey boarding houses have lower per-room land cost but higher per-room construction cost (stairs, fire separation, structural upgrade). On constrained lots, going up is often the only option.

Site conditions: Demolition of existing structures adds $15,000–$40,000 to total project cost. Asbestos removal (common in pre-1990 homes) adds $10,000–$25,000. Challenging soil (Class H or P) increases foundation costs by $5,000–$10,000 per room.

Council contributions: Section 7.12 contributions vary by council — Fairfield charges ~1% of construction cost, Liverpool charges ~1%, Canterbury-Bankstown up to 1%. These are unavoidable and should be budgeted.

Fire engineering: Boarding houses over a certain size require a fire engineering report and may need sprinkler systems ($15,000–$30,000 for the full building). This cost is spread across all rooms.

Rental Income and ROI by Room

Weekly rental income for boarding house rooms in Western Sydney (2026):

• Basic room (shared bathroom): $220–$280/week • Standard room (ensuite): $280–$350/week • Premium room (ensuite, larger, newer): $350–$420/week

A 12-room boarding house with ensuite rooms at $320/week average generates $199,680 gross annual income. After management fees (8–10%), maintenance allowance (5%), vacancy (5%), and insurance (~$5,000/year), net operating income is approximately $150,000–$160,000/year.

On a total project cost of $1.6M (construction only, excluding land), that's a gross yield of approximately 10–12% — significantly higher than standard residential rental yields of 3–4% in the same areas.

Return on total investment (including land at $900K–$1.2M) is typically 6–8% net — still strong, and the Affordable Rental Housing SEPP provides additional incentives including bonus floor space and reduced parking requirements.
