A land survey does not become unusable on one universal anniversary. For a Washington commercial property transaction, the relevant question is whether the existing survey reflects current physical and title conditions, meets the standards required for the assignment and satisfies the purchaser, lender and title insurer. An older survey may help with early review, but it should not be assumed acceptable for certification or closing.
If the transaction calls for an ALTA/NSPS Land Title Survey, the current ALTA/NSPS standards and transaction-specific requirements govern; other survey assignments may be evaluated differently.
Survey age is only the first screening question
A survey prepared recently can still be inadequate if the property, title evidence or transaction requirements have changed. A much older survey may remain useful as background, but additional research and fieldwork may be needed before anyone can rely on a current certification.
Ask what the survey was prepared for, which parcels it covered, which parties were certified, which standards governed the work and what has changed since its fieldwork. The date alone does not answer those questions.
Changes that can make an existing survey insufficient
The transaction team should flag any condition that could affect the map, certification or intended reliance:
- New construction, demolition, paving, fences or other site improvements.
- Changes in access, occupation or evidence near a boundary.
- New easements, releases, parcel changes or other recorded documents.
- A newer title commitment with exceptions that were not addressed previously.
- Different lender, purchaser or title-insurer requirements.
- A change in the parcels, property interests or off-site rights included in the deal.
- New optional work or development information requested for the transaction.
- A new version of the applicable survey standard.
The physical site and the title record can change independently. A review that considers only one of them can miss the reason the prior survey no longer answers the current transaction.
An ALTA “update” is still current survey work
The official 2026 ALTA/NSPS frequently asked questions explain that an “update” is a new survey: the surveyor is certifying current conditions and performing the assignment under the current standards. Prior work may reduce effort in some circumstances, but that depends on how much time has passed and how the property has changed.
The same guidance cautions against simply changing certified-party names or adding a current certification to old work. Certification creates reliance and professional responsibility. The surveyor must determine what research, fieldwork and documentation are necessary for the current assignment.
Current standards and title evidence matter
The 2026 Minimum Standard Detail Requirements for ALTA/NSPS Land Title Surveys apply to contracts executed on or after February 23, 2026, subject to the limited transition guidance published with the standards. The standards also require the surveyor to receive the most recent title commitment or other title evidence satisfactory to the title insurer.
That means a prior ALTA survey prepared under an earlier standard or an older title package should not be treated as current merely because the site appears unchanged. The responsible surveyor, title team and other relying parties need to resolve what the present transaction requires.
Send the right documents for an early review
Provide these materials before the transaction schedule becomes compressed:
- The complete existing survey, including its certification and any referenced sheets.
- The current title commitment and copies of relevant exception documents.
- The lender's, purchaser's and title insurer's written survey requirements.
- A description of known construction, demolition, access or occupancy changes.
- The parcels and property interests included in the current transaction.
- Any development plan that creates a need for information beyond closing.
- The requested delivery date and the parties expected to rely on the result.
The surveyor can then identify whether the prior work is useful background, whether current fieldwork and research can build from it, and whether the assignment needs a different scope.
Resolve survey acceptance before the closing deadline
The safest time to evaluate an existing survey is early in due diligence, while the team can still clarify requirements and collect documents. A lender, title insurer and development team may use the survey for different decisions, so acceptance by one party should not be assumed to satisfy every other use.
