Direct answer

Before transfer of a new-build, inspect the unit or house against the contracted specifications: water ingress, finishes, doors and windows, mechanical and electrical function, safety items, and common-area readiness that affects use. Record defects in writing, tie remedies or retentions to the SPA, and remember that inspection acceptance is separate from Department of Lands registration of ownership.

Key takeaways

  1. 1.Inspect with a written snag list before releasing final funds if the SPA allows.
  2. 2.Water, electrical, and waterproofing issues are common high-impact defects.
  3. 3.Common-area readiness can affect livability even if the unit looks finished.
  4. 4.Registration and snagging are different workflows.
  5. 5.Needs Thai legal review before transactional reliance.

Important terms

Snagging / defect list — Itemised incomplete or defective works to be remedied.

Retention — Portion of price held back pending defect rectification (only if contracted).

Handover — Keys and possession event; not automatically equal to registered ownership. (dol-home)

Detailed answer: what to check

Unit / house interior

  • Water stains, sealant failures, bathroom waterproofing signs
  • Floor and wall finishes, alignment, hollow tiles
  • Windows, balconies, railings, drainage
  • Air-conditioning performance and drainage
  • Electrical outlets, breakers, lighting
  • Water pressure and hot water
  • Built-in furniture operation

Documents and meters

  • Manuals and warranty cards if promised
  • Meter readings and utility account status
  • Parking and access fobs matching SPA inclusions

Building context (condominium)

  • Fire safety equipment visible readiness
  • Lift operation
  • Lobby and corridor finishes that affect access
  • Confirm foreign-proportion transfer readiness separately if you are a foreign freehold buyer. (thailand-go-condo)

Step-by-step

  1. Book inspection with enough light and water/power available.
  2. Bring SPA specs and brochure promises that were contracted.
  3. Photograph and list each defect with location.
  4. Deliver the list under the SPA notice clause.
  5. Negotiate repair timeline or retention before final payment if allowed.
  6. Proceed to Land Office transfer as a separate checklist. (dol-home)

Hypothetical example

Assumed facts: Buyer transfers and pays in full, then discovers balcony drainage floods the bedroom in the first rain. SPA defect clauses are thin after acceptance.

Lesson: Push inspection and written remedies upstream of final payment where the contract permits.

Risks

  • Pressure to accept incomplete units to meet developer transfer targets.
  • Unqualified “inspections” that miss systemic waterproofing issues.
  • Confusing keys handover with title registration.
  • Warranty periods that start before defects are documented.

Checklist

  • SPA inspection rights identified
  • Written snag list with photos
  • Critical systems tested (water, power, AC)
  • Inclusions matched to SPA
  • Repair/retention terms agreed if needed
  • Transfer registration checklist run separately

FAQ

Do I need a professional inspector?

For many buyers, yes—especially for waterproofing and electrical. Counsel can help coordinate.

Can I refuse transfer because of snags?

Depends on SPA rights and defect severity. Get advice quickly; do not rely on gallery assurances.

Does inspection replace title diligence?

No. Title, encumbrances, and foreign-proportion checks remain separate.
