Commission an investigation of the house and its site
A Moss Beach inspection should connect the residence’s visible condition with its permits, drainage, foundations and practical access. A recently finished interior does not answer the site questions, and a neighborhood geologic report does not inspect a roof. Begin with the particular property and the spaces the buyer intends to use. The Moss Beach guide introduces these systems; the inspection file should identify who will assess each one and what evidence they need.
No private residence was inspected or photographed for this draft. The original question guide below uses actual dated photographs in the County-commissioned Seal Cove study as documentary teaching examples, with links to the source. Those images depict specific public-area conditions in 2025. They are not photographs of a candidate home, current roadway observations or evidence that all Moss Beach properties share the conditions shown. The guide organizes questions for qualified reviewers without diagnosing an unseen structure.
Establish the existing layout before interpreting improvements
Ask for reliable existing-condition information and compare rooms, additions, outbuildings and separate living spaces with the available approval history. The public 210 Marine Boulevard record, PLN2026-00152, provides a useful documentary example. Its description concerns a 420-square-foot addition, bathroom, fence and lot merger, while a separate notice refers to a proposed attached ADU. An inspector should receive the controlling drawings and actual scope, not a summary that silently combines different entries.
The displayed planning status was Approved when checked. That does not establish a completed construction inspection or an approved final layout. Keep planning decisions, construction permits, revisions and final records in separate parts of the file. Where the house differs from the documents, identify the feature and ask the appropriate agency or professional what further evidence is required. Missing online history is a reason for a targeted records inquiry, not an automatic conclusion about the legality or condition of the work.
Read the local geologic report with its limits attached
The Seal Cove Geologic Study has a December 11, 2025 signed transmittal. It considers landsliding, faulting and bluff failure, and describes a relatively level marine terrace near steep coastal features. This helps explain why surface appearance alone is an incomplete screening method. A flat-looking yard cannot establish subsurface stability, and a photograph of distress elsewhere cannot determine the cause of a crack in the subject residence.
Printed page 33 explains that the report relies on reconnaissance and other consultants’ investigations, without new subsurface exploration or laboratory testing for that study. Supply it to the relevant qualified reviewer along with any property-specific reports. Ask which maps apply, whether the earlier work addresses the intended project and what additional investigation is needed. The report’s recommendations should not be represented as a parcel clearance, completed stabilization or proof that the County has adopted every proposed map revision.
Turn the dated photographs into better questions
Appendix D’s Photo 1, dated June 25, 2025, shows a scarp and roadway distress along Ocean Boulevard between San Lucas and La Grande avenues. The caption’s location, direction and date are as important as the visible feature. They let a reviewer connect the photograph to the report rather than an unidentified image shared without context. They do not establish that another property’s pavement damage has the same origin or that the photographed route is currently available.
Photo 4, also dated June 25, 2025, identifies cracking and a sinkhole along San Lucas Avenue between Ocean Boulevard and Del Mar Avenue. Use it to ask how a proposed inspection will document site features, establish the limits of accessible observation and refer unresolved ground questions. Do not ask a general building inspection to supply a geotechnical conclusion outside its agreed scope. Any current visit must respect actual restrictions and should not enter a damaged or closed area to recreate an old photograph.
Original source-photo and document question guide
Read with the December 2025 County study, Appendix D. Source photographs remain in that report; no original private-site photographs or field inspection are claimed. Guide checked October 26, 2026.
| Reference | Documented context | Question for the subject-property reviewer | Limit |
|---|---|---|---|
| Photo 1, PDF page 86 | Ocean Boulevard roadway scarp; June 25, 2025 | Which site features need location-based observation, survey or specialist investigation? | No transfer of cause or condition to another parcel |
| Photo 4, PDF page 89 | San Lucas Avenue cracking and sinkhole; June 25, 2025 | What are the access limits and unresolved ground questions? | No current route or safety certification |
| Report printed page 33 | Reconnaissance and reviewed investigations; no new subsurface work | Does the actual house require additional investigation? | Neighborhood report is not a house inspection |
| PLN2026-00152 | Addition description and separate ADU notice | Which approved drawings and completed inspections match existing spaces? | Planning Approved does not establish completed construction |
For each actual finding, record location, observation date, access limitation, reviewer, supporting record and next action. Leave cause and repair scope unresolved until the appropriate review supports them.
For new property photographs, agree on a location and labeling method before the visit. Retain an overview that places the feature on the site and a closer image that shows the observation, with the date and any access limitation. A close-up without that context can be confused with a different wall, drain or paved area. Permission and safe access must be established for the actual property. The County report examples demonstrate documentation questions; they do not provide substitute photographs of the house being purchased.
Trace drainage from the building to its receiving system
Ask the inspector to document accessible roof drainage, surface grading and visible discharge points. Where a pipe disappears or connects beyond the property, identify the missing evidence rather than guessing its route. Request any relevant drainage plans, repair records and responsibilities for shared or public facilities. Photographs should be tied to a plan or clear location reference so the next reviewer can distinguish an inlet, an outlet and an unrelated feature.
The County’s Seal Cove drainage project was in data collection after its August 2026 kickoff. It is a public planning study, not confirmation of repaired private drainage. The geologic report also cautions that roadway drainage improvements would have limited effect on the larger landslide’s stability. A proposal to redirect water should therefore be reviewed for its own scope and discharge consequences, rather than described as a guaranteed cure for a foundation or ground condition.
Match foundation and structural questions to qualified review
For the actual residence, request available foundation plans, alteration records and prior technical reports. Ask the inspector to distinguish accessible observations from concealed areas and identify when structural or geotechnical input is needed. Record an observed crack’s location and context without assigning a cause from its appearance alone. A repair proposal should explain the condition it addresses, the supporting investigation and any limits on access or verification.
Separate the house’s structural system from retaining walls, paved areas, fences and other site improvements. Their ownership and functions may differ, and one contractor’s scope may not cover all of them. If a feature supports a driveway or affects access for repair equipment, identify that relationship explicitly. This gives the appropriate reviewers a concrete question about the whole project instead of a request to approve a vague description such as ordinary settlement.
Inspect roofs and exterior assemblies as actual systems
Ask about the roof’s age evidence, accessible condition, prior repairs, drainage details and the limitations of the inspection. Do the same for windows, cladding, exterior connections and exposed metal. The coastal setting is a reason to document materials and maintenance history carefully. It is not enough to assign a standard replacement interval or presume that every exterior needs the same work. A fresh finish should be reconciled with the underlying repair record.
When further work is recommended, obtain a defined scope with quantities, access assumptions and unresolved concealed conditions. Keep exploratory work separate from a final replacement estimate. If a roof or exterior project changes other systems or requires agency review, ask the responsible reviewer to identify that route. A precise price for a narrow visible repair should not be presented as a complete allowance for an assembly that has not been investigated.
Verify access and close the evidence gaps
The County’s Seal Cove information page includes historical roadway issues. Those notices do not establish current access to a candidate property in October 2026. Confirm the actual approach, any current restrictions and the legal rights supporting it. Also consider access needed for inspectors, emergency response and future maintenance. A route that is usable for a passenger car may still require separate planning for a particular repair operation.
Complete the investigation log with the material unanswered questions, responsible reviewer and evidence needed before reliance. The San Mateo County guide provides jurisdiction context, and the buying-process guide helps organize the transaction steps. The useful result is a coordinated account of the actual house and site, including what was observed, what the records establish and what still requires qualified assessment.
