How to start a defect inspection company in Singapore

Singapore’s private and HDB new-home market creates steady demand for independent defect inspection. After Temporary Occupation Permit (TOP) and key collection, buyers typically get a 12-month Defects Liability Period (DLP) under the standard Sale and Purchase Agreement framework — during which the developer must rectify defects due to poor workmanship, materials, or non-compliance with specifications. Buyers who want a clear paper trail hire professional inspectors rather than relying on a casual walkthrough and a phone gallery.

Starting a defect inspection company here is less about inventing a new service and more about getting the ACRA registration, CONQUAS-grade professional standards, and report tooling right from day one. This guide covers all three — and the step that most new founders under-invest in: using purpose-built software so every job produces a branded PDF and developer-ready evidence pack.

1. Understand the service you are selling

Most commercial defect inspection firms in Singapore focus on buyer-side TOP / handover / DLP inspections for new condominiums, landed homes, and sometimes HDB units:

• Full unit walkthrough by area (entrance, living, kitchen, bedrooms, baths, balcony, yard / PES)
• Photo evidence of cracks, hollow tiles, alignment / lippage, water ponding, socket failures, and finishing defects
• A structured report the buyer can attach when submitting the developer’s defect form
• Optional re-inspection after rectification

That is related to — but not the same as — CONQUAS® (Construction Quality Assessment System), the Building and Construction Authority’s (BCA) national benchmarking system for construction workmanship on new building projects. CONQUAS assessments are commissioned on projects (often by developers / builders) and scored against defined workmanship standards across components such as structural, architectural, and M&E works (exact component weighting follows the applicable CONQUAS manual / tender date rules). Buyer-facing DLP inspection is a commercial service; CONQUAS is an industry quality benchmark. Serious firms still train to CONQUAS / BCA workmanship thinking so their defect calls match what developers and contractors already recognise.

Related BCA concepts worth knowing when you market yourself:

• CONQUAS score / banding — project-level workmanship benchmark (increasingly visible to buyers as transparency rules evolve)
• Quality Mark (QM) — a higher, often unit-level quality scheme for internal finishes (distinct from your buyer inspection report, but useful industry literacy)

Also note: there is typically no single national “building inspector” licence just for commercial buyer-side DLP inspection. Credibility comes from ACRA registration, construction-related competence, clear methodology, insurance, and professional report output.

2. Choose a business structure (ACRA)

For a serious inspection brand that will issue formal PDFs, invoice clients, and later hire inspectors, a Pte. Ltd. is usually the better long-term vehicle.

Pte. Ltd. statutory requirements (practical checklist)

• At least one shareholder (individual or corporate; 100% foreign ownership is generally allowed for this type of services business)
• At least one director who is ordinarily resident in Singapore (Singapore citizen, PR, or eligible pass holder such as Employment Pass / EntrePass / S Pass — confirm current ACRA residency rules)
• A qualified company secretary who is a natural person resident in Singapore, appointed within 6 months of incorporation (cannot be the sole director if you only have one director)
• A Singapore registered office address (not a P.O. Box) that is accessible to the public for at least three hours on each business day
• Minimum paid-up capital often cited as S$1 (banks and passes may expect more in practice)
• Principal activities / SSIC codes that match inspection / consultancy services

Register via BizFile+ (ACRA)

Incorporation is filed online through ACRA’s BizFile+ portal (Singpass required for DIY filing). Foreign founders without Singpass typically engage an ACRA-registered Corporate Service Provider (CSP) to file on their behalf.

Typical path:

1. Reserve the company name — fee commonly S$15; approved name usually reserved for 120 days
2. Prepare constitution (ACRA model constitution is fine for many startups), director / shareholder / controller details, registered address, FYE, and share capital
3. Register the local company via BizFile+ — incorporation fee commonly S$300 (about S$315 total government setup with name reservation)
4. Officers endorse as required; ACRA issues the Unique Entity Number (UEN) and incorporation confirmation (often same day to 1–3 business days for straightforward filings)
5. Appoint company secretary (if not already), open a corporate bank account, and complete tax setup

Budget realistic 2–6 weeks from start to a fully operational company when you include bank account opening and basic compliance setup.

3. Complete post-incorporation compliance

ACRA registration alone does not mean you are fully ready to trade. Common next steps:

1. Corporate bank account — bring ACRA / BizFile documents, director IDs, and proof of address.
2. IRAS tax registration — corporate income tax applies; register for e-filing / Corppass as required.
3. GST — register when taxable turnover exceeds the prevailing threshold (commonly S$1 million — confirm current IRAS rules).
4. CPF — mandatory employer contributions once you hire employees who are CPF-liable.
5. Workplace / office approvals — if you operate from HDB residential premises or certain industrial spaces, check HDB / URA / landlord rules before advertising a walk-in office.
6. Professional indemnity insurance — strongly recommended; defect reports are used in developer disputes and claims.

Keep annual ACRA filings (annual return) and secretary-led compliance on calendar from day one — missed filings create unnecessary risk for a young brand.

4. Build CONQUAS-aligned professional capability

To position as a professional defect inspection company — not a “photo guy with a WhatsApp folder” — invest in standards literacy:

Learn CONQUAS / BCA workmanship thinking

CONQUAS (BCA) measures construction workmanship quality using defined standards and sampling. Professional inspectors should be able to:

• Recognise common architectural finish defects (hollow tiles, lippage, alignment, jointing, paint, waterproofing symptoms)
• Understand how structural and M&E checks differ from finish checks (and when to escalate beyond a commercial DLP report)
• Use measuring tools consistently (level, square, moisture meter, socket tester)
• Document defects in a way that maps cleanly to developer rectification forms

Even if your day-to-day work is buyer DLP inspection (not formal CONQUAS project scoring for a developer), CONQUAS literacy is one of the strongest credibility signals in Singapore.

Equip a field kit

Minimum professional kit usually includes:

• Smartphone with good camera (and backup power)
• Spirit level / laser level
• Socket tester
• Torch, measuring tape, hollow-tile tapping tool
• Moisture meter (useful for wet areas)
• Optional: thermal camera for advanced packages

Define your methodology and disclaimer

Write down what you inspect, what you do not inspect (e.g. PE structural certification, latent structural investigations), how you code photos, and how clients should use the report inside the DLP notice process. Consistent methodology is what makes your PDFs look like an agency product.

5. The most important step — run the business on Defiq Inspect

This is the step that separates a scalable inspection company from a lifestyle side hustle.

The inspection itself is only half the job. The other half is producing a developer-ready paper trail at speed: coded photos, legends, branded PDF, and an evidence pack the buyer (or your office) can submit without rebuilding the report in Word every night.

Without purpose-built software, the typical loop is: phone camera → WhatsApp dump → evening Word/Excel report → 2–4 hours of photo insertion and legend typing per unit. That caps how many jobs you can take and keeps your reports looking like DIY documents — which makes it hard to charge professional fees in Singapore’s competitive market.

Defiq Inspect is built for Singapore and Malaysia defect inspection companies to run capture → report → developer handoff in one system:

Field capture that writes the report as you walk

• Area-by-area capture with automatic photo codes (A01, A02…)
• One-tap element + issue tagging (wall / floor / ceiling × crack / hollow / mould, etc.)
• Annotation on photos when you need to circle a hairline crack
• Multi-inspector area claiming when you grow beyond a solo founder

Professional report generation

• Branded PDF with cover, property information, photo grids, legend tables, socket / spirit-level / water-ponding pages, and disclaimer
• Structure aligned with how serious Singapore handover reports are expected to look — including CONQUAS-aware workmanship framing in the product design
• Consistent output so every client report matches your company standard

Developer export

Buyers often need a subset of evidence for developer portals, email tickets, or rectification packs — not only the full client PDF. Defiq Inspect’s Export for Developer flow lets you select and package proportional photo sets (individual photos, category collages, or report pages) so office staff can submit evidence without re-exporting hundreds of camera-roll files by hand.

Practical recommendation: start on Defiq Inspect Starter (SGD pricing available; first month free on the website path) so your first client reports already look agency-grade. Upgrade to Professional when you hire inspectors or need custom report templates on the web admin portal at app.defiq.app.

6. Price and go to market

Under-pricing is a common early mistake. If your only tools are free (phone + Word), founders undercharge — then discover they cannot afford time, insurance, or growth. Agencies that deliver structured, photo-coded, legend-based handover reports can justify professional fees that reflect the value of the DLP paper trail, not the cost of a free camera app.

Your Defiq Inspect subscription (Starter from SGD 99/month) is typically less than one properly priced inspection job. Price for the value of the report — not for the cost of free tools.

Go-to-market channels that work in Singapore:

• Property agent and conveyancing lawyer referrals near new launches / TOP batches
• Condo Facebook / Telegram groups at key collection
• Partnerships with renovation contractors (inspect before renovate)
• Clear sample PDF on your website (Defiq can generate branded samples once you are set up)

7. First-90-days checklist

1. Decide sole prop vs Pte. Ltd.; complete ACRA BizFile+ registration (or engage a CSP)
2. Appoint company secretary; open bank account; set up IRAS / Corppass
3. Confirm office / home-office rules for your registered address
4. Buy field kit + professional indemnity cover
5. Complete CONQUAS / BCA workmanship familiarisation
6. Subscribe to Defiq Inspect; configure company name, disclaimer, and report template
7. Run 2–3 practice units end-to-end (capture → legends → PDF → developer export)
8. Publish pricing packages and a sample report; start referral outreach

Starting a defect inspection company in Singapore is achievable: register properly with ACRA, train to CONQUAS-grade workmanship standards, and use software that turns site photos into professional PDFs and developer-ready exports.
