Count the accommodation being offered
An advertisement’s bedroom field may describe the property loosely. Review the floor plan and dated text to determine how many separately offered rooms existed at the relevant time. Distinguish residents, bedrooms, suites and rooms available for rent; those counts need not be interchangeable.
Keep the source for each count. If a room number cannot be verified, label it unknown rather than zero or the target number. Missing values otherwise become invented product matches or disappear from the denominator without explanation.
Check the bathroom arrangement for each room
A property with several bathrooms is not necessarily a property with an ensuite for every room. Look for which room connects to which bathroom, whether access is private or shared, and what the advertisement actually states. Store the verified ensuite count separately from the total bathroom count.
Terms such as “studio”, “suite” or “private facilities” need context. Where a plan is unclear, keep a partial or unknown classification. Re-reading the same promotional text with a model does not turn an unclear statement into independent evidence.
Compare the rest of the operating product
Record kitchens, laundry, common spaces, storage, furnishing, access and the division of bills where known. Two ensuite properties can still have different operating arrangements and resident propositions. The comparison should make those differences visible rather than relying on room count alone.
Check statutory requirements through the relevant official sources and project advice. CAV publishes rooming house minimum standards covering safety and amenity. Meeting a research product filter is a different question from meeting all applicable requirements.
Explain what the chosen filter leaves out
A narrow ensuite filter removes shared-bathroom properties that describe a different product, but it also excludes properties whose advertisements omit the relevant detail. Show the number with confirmed product evidence and the number with missing evidence separately.
Do not describe an exclusion as proof that the property is inferior or unlawful. It may simply be unsuitable for this comparison. A broader secondary group can help explain the market, provided it remains labelled and is not silently added to the target-product median.
Translate the product into a deliverable specification
For a new build, turn the comparison into a room schedule showing the intended facilities and shared areas. Carry the same schedule into design, quotations and operating preparation. Otherwise the market benchmark and the building contract can end up referring to different products.
Confirm use, building assessment and operation independently with the appropriate professionals and authorities. Check property and operator records for the question each answers. A public register search should not be used as a shortcut for judging a new design’s complete compliance.
Documents to take to the next conversation
- Dated room schedule and source-backed separately offered room count.
- Private, shared, partial or unknown bathroom access recorded by room.
- Shared facilities and operating arrangement compared explicitly.
- Research selection separated from planning, building and operating checks.
Questions owners ask
Does eight or nine ensuite rooms define a legal rooming house?
No. It describes a selected comparable product. The applicable legal definition and project requirements must be checked separately.
What if the advertisement does not say every room has an ensuite?
Keep the ensuite arrangement unknown or partial unless another reliable record establishes it. Do not infer a full match from the property’s total bathroom count.
