Queensland Modular Home Quote and Deposit Checklist

The short answer

A useful Queensland modular home quote should do more than price the factory-built modules. It should identify the legal contracting entity, the proposed building use and classification, the property assumptions, approval documents, foundations, transport, installation, services, inspections and handover records.

Give every shortlisted builder the same written brief, then mark each line as included, excluded, provisional or not stated. A lower factory price is not a saving if the buyer still has to organise engineering, approvals, footings, freight, cranage, connections and completion work.

Start with the Queensland modular home builder directory, then use this checklist before treating any proposal as a complete project price. The directory is a research starting point, not a ranking, and current licence, service-area, price and availability details should be confirmed directly.

This guide is general information. Queensland planning, building, plumbing, contract and insurance requirements depend on the property, intended use and contractual arrangement. Confirm the project with the relevant council, a private building certifier, the QBCC and qualified advisers before signing or paying.

First, describe the project without sales labels

“Modular”, “prefab”, “transportable”, “kit”, “pod” and “tiny home” can describe overlapping products. They do not tell you who finishes the building or what approval pathway applies.

Put these facts at the top of the quote request:

• property address and local government area
• intended use: principal home, secondary dwelling, guest accommodation, short-stay cabin, farm-stay cabin, studio or another use
• proposed number of occupants and bedrooms
• whether the home is fixed to land and connected to services
• preferred floor plan, module count and finish level
• known zoning, flood, bushfire, coastal, wind, slope, soil or access constraints
• available water, wastewater, electricity and stormwater arrangements
• target timing and complete-project budget
• work the buyer expects the builder to manage

The Queensland Government's tiny homes guidance explains that a fixed, self-contained home used as a residence is treated as a dwelling under the planning framework. It also separates permanent dwellings from temporary movable accommodation. That distinction should be settled for the actual proposal rather than inferred from a brochure or the presence of wheels.

Match the business name, licence and contract

Ask the supplier to write down every business involved in design, manufacture, transport, installation and site completion.

For each one, record:

Search the proposed entity in the QBCC register. Do not accept a licence number belonging to a related company, director or subcontractor without understanding which entity is contracting with you.

The QBCC's current tiny home, prefab and modular guidance says a fixed tiny home used as a Class 1a dwelling must be installed by an appropriately licensed contractor. The same guidance notes that Queensland Home Warranty Scheme cover may apply to on-site residential construction work while not covering the off-site manufacturing component. Ask the QBCC about the actual contracts instead of assuming one scheme covers the whole factory-to-handover journey.

Put approvals and evidence into the quote

“Approval ready” and “built to code” are not deliverables. Ask the builder to list each document, the person responsible for preparing it, the fee, the due date and whether it is included in the quoted price.

The schedule may need to address:

• site survey and property information
• soil test and site classification
• wind classification and site-specific structural engineering
• architectural and construction drawings
• energy-efficiency assessment
• bushfire, flood, coastal, acoustic or other site reports where relevant
• foundation and tie-down design
• evidence of suitability for products and systems
• planning advice or application documents
• building approval and inspection documents
• plumbing and drainage design, permits and inspections
• wastewater design where the property is not sewered
• final inspection, occupancy or completion documents applicable to the project

The QBCC's Class 1a prefabricated homes fact sheet, effective November 2025, highlights site-specific evidence such as soil information, wind assessment and National Construction Code evidence of suitability. A standard model's documents may be useful, but they do not prove that the same foundation, tie-downs, glazing, waterproofing or climate response suit a particular Queensland block.

Most domestic building work needs a building approval before it starts. Business Queensland explains that approvals may be obtained through a local government or building certifier. Planning, plumbing, wastewater and local-law questions can still sit elsewhere. Ask for one responsibility schedule covering all of them.

Divide the quote into five scopes

A clear quote separates work by location and handover point.

If one supplier says “turnkey”, ask it to complete the same table. Turnkey may describe a finished module while still excluding the work needed to lawfully place, connect and occupy it.

Use the tiny home quote scope checker to turn the builder's written answers into an inclusion-and-gap summary. It does not review the contract or decide whether the price is fair.

Make the factory price comparable

Record the exact model, revision date and specification attached to each quote. Then check:

• module dimensions, transport dimensions and expected finished weight
• structural system and corrosion treatment
• insulation values, glazing, shading and ventilation
• internal lining, flooring and painting
• cabinetry, benchtops, fixtures and appliances by model or allowance
• heating, cooling, hot water and electrical provision
• wet-area and waterproofing documentation
• external cladding, roof, gutters and stormwater outlets
• decks, verandahs, stairs, balustrades and accessibility items
• design changes included before additional fees apply
• GST, escalation clauses, allowances and expiry date

Do not compare a shell, lock-up module and finished dwelling as though they are the same product. The shell versus turnkey guide lists common work that can remain after a cheaper shell leaves the factory.

Price the Queensland site, not an average block

The builder needs enough property information to price or clearly exclude the site risk. Queensland projects can differ sharply across coastal, cyclonic, flood-prone, bushfire-prone, sloping and remote locations.

Ask what the quote assumes about:

• soil and founding conditions
• slope, cut and fill, retaining and drainage
• wind region and site wind classification
• flood level, overland flow and minimum floor height
• bushfire assessment and construction response
• salt, humidity, termite and corrosion exposure
• driveway width, corners, grades and wet-weather access
• overhead powerlines, trees, gates and neighbouring property
• crane setup, outrigger loads and ground bearing capacity
• sewer, onsite wastewater, water storage and electrical supply
• distance for trades, certifier inspections and warranty visits

If the site has not been inspected, the quote should say which amounts are allowances and what information could change them. The site preparation checklist helps turn a general property discussion into written survey, access, foundation, services and drainage tasks.

Make delivery a priced work package

“Delivery included” is incomplete unless it names the destination and endpoint.

Confirm:

1. factory or pickup address
2. delivery property and route assumptions
3. module dimensions and load type
4. road permits, pilots, escorts and traffic management
5. overhead and roadside clearance work
6. transit insurance and responsibility for damage
7. crane, side-loader or other placement equipment
8. agreed site-ready conditions
9. weather and failed-delivery charges
10. module joins, sealing, levelling and tie-downs
11. packaging removal and site reinstatement
12. return visits for testing and defects

A builder located in Queensland can still have a long or difficult route to the site. A builder based interstate may service the postcode but rely on local contractors for installation and completion. Compare the written chain of responsibility, not only the factory distance.

The delivery and installation checklist covers route, crane, placement and handover planning in more detail.

Check deposits and factory progress payments

Off-site manufacturing can produce payment stages that differ from a conventional site build. Before paying, ask:

• which Queensland contract rules the supplier says apply
• how the deposit was calculated
• whether an off-site fabrication exception is being relied on
• what work and materials each progress payment represents
• how the buyer can inspect or verify completed factory work
• whether the lender accepts the proposed stages
• who owns identifiable modules and materials after payment
• who bears storage, damage and insolvency risk before delivery
• what happens if approvals, finance or site readiness are delayed

The QBCC's deposit and progress payment guidance describes different deposit limits and an off-site fabrication exception in some circumstances. Whether those rules apply depends on the actual contract. Have an unusual, high-value or split factory/site arrangement checked before transferring a substantial deposit.

Use the broader Australian tiny and modular home contract checklist for variations, delays, termination, defects and dispute terms. If finance is required, take the proposed factory stages to the lender before signing; the modular home finance checklist explains the valuation and drawdown questions.

Require a Queensland handover document list

Final payment should be tied to a defined completion point, not simply the day the modules arrive.

Ask which party supplies:

• approved plans and final specifications
• engineering, inspection and product evidence
• electrical, plumbing, gas and other trade certificates
• waterproofing and glazing records where relevant
• testing and commissioning results
• occupancy or final documentation applicable to the project
• appliance manuals, keys and warranties
• maintenance instructions
• defects list and rectification timetable
• contact details for post-handover service

The QBCC's handover and final documentation guidance distinguishes contract completion paperwork from regulatory approval to occupy. Make both visible in the quote and contract.

A one-page comparison before you shortlist

For each builder, answer these 12 questions without relying on a phone conversation:

1. Which legal entity signs the factory and site contracts?
2. Which QBCC licence and insurance arrangements apply to each work package?
3. What use, classification and approval pathway does the quote assume?
4. Which site-specific reports and compliance documents are included?
5. Is the factory scope shell, lock-up, finished module or completed dwelling?
6. Which foundation, access, service and external works remain with the buyer?
7. Is transport priced to the actual address and module dimensions?
8. Who installs, joins, connects and certifies the completed home?
9. Which amounts are fixed, provisional or subject to variation?
10. Can factory progress payments be independently verified and funded?
11. What documents and work define handover and lawful occupation?
12. Who returns to fix defects, and are regional travel costs included?

When the answers are complete, compare the Queensland modular builder listings on fit, scope and verification—not on a directory label. For buyers considering a compact, more design-led prefab cabin, Zinc Studio's profile is one premium option to include in the same documented comparison. Confirm current Queensland delivery, installation, approvals support, pricing and availability directly with Zinc.

FAQ

Does a Queensland modular home need building approval?

Usually, a fixed home used as a dwelling will need building approval, and plumbing or planning requirements may also apply. The exact path depends on the property and proposal. Confirm it with the council and a private building certifier before ordering.

Does QBCC licensing cover the factory and installation?

Do not assume one licence or protection covers every stage. Manufacturing, supply, transport, on-site installation and residential building work can sit under different arrangements. Check the legal entities, licence classes, contracts and Queensland Home Warranty Scheme position for the actual project.

What should a modular home quote include?

At minimum, it should identify the design and specification, approval documents, factory scope, foundations, transport, installation, services, site exclusions, payment stages and handover records. Any missing line should be treated as unresolved rather than included.

Are Queensland modular homes cheaper than conventional homes?

Not automatically. Factory construction can change timing and site labour, but transport, cranage, foundations, services and approval work remain. Compare complete site-specific scopes rather than base prices or square-metre claims.

How many modular builders should I quote?

Two or three well-matched builders with the same brief can be more useful than many loosely comparable prices. First check service area, project type, licence position and whether the supplier will price the complete scope you need.
