Use the inspection to connect the house with its site
A Tomales inspection should examine how the roof, foundations, drainage and access work together on the actual property. A house-only checklist may overlook a driveway change, private water equipment or a separate outbuilding. Begin with the buyer’s concerns and available plans, then ask the inspector to identify what was observed, what could not be reached and which questions need a specialist. A public planning file helps frame that work; it cannot substitute for a current permissioned inspection.
The Tomales guide introduces the area, and the Marin County guide supplies broader context. Use this article within the buying process to prepare a focused inspection request. The original sketch below is a question guide rather than a photograph of an inspected home. No permissioned property photographs, private observations or structural findings were supplied for this draft.
Read the local proposal without treating it as an inspection
The applicant statement for 100 John Street, APN 102-073-05, describes proposed driveway and grading work associated with an ADU. It also discusses an existing well and water tower and a proposed sewer lateral. These descriptions identify useful areas to investigate: the relationship between the house and ground, circulation and buried or mechanical services. They do not establish current drainage performance, completed construction or the physical condition of any component. John Street applicant statement.
Give the inspector the applicable drawings and distinguish the existing layout from proposed changes. A proposed line on a plan should not be described as an observed drain or installed lateral. Ask the owner for construction photographs, invoices and maintenance records where available, keeping their dates and sources visible. If the physical arrangement differs from the documents, record the difference for follow-up rather than deciding from the discrepancy alone that work is defective or unauthorized.
Trace roof water to its actual destination
Start at the roof and follow the visible route of water through gutters, downspouts and any surface or buried connections that can be evaluated safely. Ask which sections were accessible and whether conditions permitted observation of flow. An attractive roof surface does not identify where runoff goes, while an inaccessible drain outlet should remain an inspection limit. Request a clear distinction between an observed condition, an inferred route and a recommendation for further evaluation.
For a property with several buildings, identify each roof separately. A house, garage, shed and water-tower structure may require different access and different expertise. Do not let a report about the main residence imply that every accessory structure was inspected to the same extent. The John Street materials name several improvements, making that scope question locally concrete without establishing that any of them currently needs repair.
Ask a roofing specialist to define the location and scope of any recommended work before pricing it. A quotation should identify whether it covers a localized repair, drainage accessory or a larger roof project and what was excluded. Keep the quote separate from a prediction about the entire roof’s remaining life unless the specialist supports that conclusion. No replacement interval or Tomales-wide roofing cost can be derived from the public project examples.
Give foundations and ground conditions distinct questions
Ask the inspector to describe accessible foundation areas and any observed movement, moisture or alteration, with location references. A report should make clear whether a crawlspace, perimeter or other relevant area was inaccessible. If a concern requires structural or geotechnical review, provide the specialist with the observation and applicable site documents. Neither a planning approval nor an applicant’s description of gentle grading certifies the present foundation or underlying ground.
The Shoreline One P6126 index, for 28200 State Route 1, lists a geotechnical report alongside drainage, flood and biological reports. The listed documents were not reviewed in detail for this article, so their findings are not assigned to the property. Their practical value here is to show why a buyer should request the actual specialist file, verify its parcel and revision, and ask how its scope relates to the existing residence and intended changes. County report index.
A report prepared for a proposed building may answer different questions from an inspection of an older house. Identify the area investigated, the proposed design it addressed and any limitations before applying it to another structure. Ask the appropriate professional whether supplemental work is needed. This is especially relevant when a listing presents a large folder of plans: the quantity of material does not establish that every foundation or retaining feature has been evaluated.
Review drainage as a property system
Walk the accessible site with the inspector’s scope in mind and identify visible drainage features, changes in grade and places where maintenance history is important. Ask where water is intended to enter and leave the property and which documents support that description. Avoid extending the inspection onto neighboring land without permission. A buyer needs to understand the subject property’s arrangement and any documented shared responsibility rather than infer ownership from the direction of runoff.
Record weather and observation limits. A dry-day visit may reveal staining or sediment without showing active flow; a wet-day observation still represents particular conditions. Ask the owner for dated accounts of drainage work or past problems and have appropriate specialists evaluate unresolved concerns. The objective is a traceable history and a defined next step, not a claim that one visit proves performance through every season.
Conceptual sections only. No actual property dimensions, photographed defects, measured slope or professional diagnosis is represented.
1. Roof edge
Roof → gutter/downspout → visible outlet
Ask: Which portions were reached? Is the discharge route observed or inferred?
2. Ground and structure
Ground surface → foundation perimeter → accessible interior support
Ask: What was observed? Which areas need structural or geotechnical review?
3. Drive and services
Road/drive → buildings → water and wastewater components
Ask: What is existing, what is proposed, and who maintains each component?
| Observation or question | Supporting evidence | Next reviewer |
|---|---|---|
| Roof discharge unknown | Inspector location reference, access limit and applicable drain plan | Appropriate roofing/drainage specialist |
| Ground/foundation concern | Actual observation and correct parcel-specific report | Qualified structural or geotechnical professional |
| Driveway/site change | Existing condition versus proposed plan and actual approval | Applicable County/road/fire authority and specialist |
| Water or wastewater uncertainty | Current source/account, system file and maintenance history | Provider or qualified system reviewer |
Local research prompts: John Street proposal, P6126 report index and County onsite-system route. Applicant material and report listings are not inspected conditions.
Inspect access and responsibilities together
The John Street statement’s driveway and circulation discussion is a prompt to inspect the actual route, not proof of a recorded access right or current emergency-access compliance. Match the drive and any proposed changes to applicable plans, title instruments and agency requirements. Ask the inspector to identify physical concerns within the agreed scope, while the title and agency reviewers address the separate rights and approval questions.
Keep maintenance responsibility specific. If a route or drainage feature is shared, request the actual agreement and available work history. Identify which portions the seller maintains and whether that account is supported by documents. If a repair would require equipment access, ask the contractor to explain how it would be performed and what assumptions the quote makes. A visible connection to the public road does not resolve every private obligation along the way.
Keep mechanical systems in the inspection scope
Confirm whether the actual house uses district sewer or an onsite wastewater system, and independently identify the domestic water source. Tomales Village Community Services District’s wastewater role is not a drinking-water guarantee. For a well and storage arrangement, obtain equipment and testing records and ask a qualified professional what can be evaluated. For onsite wastewater, request the County file and appropriate current system review rather than infer capacity from the number of visible bedrooms. District role; County system records.
Keep repair authorization separate from the physical inspection. Marin’s coastal-exclusion guidance describes criteria and an agency route; it is not a blanket permission for every project an inspector recommends. Define the actual scope and ask the County which approvals apply before relying on a construction schedule. An inspection finding helps identify work to investigate, while the agency determines the applicable permit process. Coastal guidance.
Finish with an actionable inspection record
Organize the report by location and component, with the observation, limitation, supporting document and next reviewer together. Resolve whether a concern affects the buyer’s intended use, an immediate repair decision or longer-term maintenance. That produces a practical Tomales house-and-site file: roof water has a documented route, foundation questions have an appropriate reviewer, access responsibilities have their own evidence and system assumptions remain visible until confirmed.
