Foundation & Drainage Inspection-Prep Workbook
Before an engineer or contractor inspects your foundation, drainage, structural alterations or retaining walls, the most useful thing you can bring is organized documentation. This workbook helps you gather it. It does not diagnose anything, it cannot tell you whether repair is needed, and it never asks for your address.

Read first: when to stop documenting and call a professional
This workbook cannot assess safety. If anything you observe feels urgent, stop documenting and contact a qualified structural engineer or, in an emergency, your local building department.
Rapidly changing cracks or new displacement
If a crack is visibly growing over days or weeks, or a wall or floor has newly shifted, treat it as urgent and arrange an on-site evaluation by a qualified structural engineer promptly.
Doors or windows suddenly inoperable
Sudden racking of openings can indicate active movement. Do not force them; document and seek qualified on-site evaluation.
Retaining wall leaning, bulging or weeping heavily
A retaining wall showing active distress can fail with little warning, especially during storms. Keep people away from the base and arrange prompt professional evaluation.
Water entering living space or pooling against the foundation
Active water intrusion during storms warrants prompt attention from qualified drainage and structural professionals.
After an earthquake or major storm
If you observe new cracks, offset, or leaning after a significant event, have the home evaluated by a qualified professional before occupying affected areas if you have any safety concern.
Observation categories
Mark each category as you walk the property. 0 of 6 categories reviewed.
Visible foundation surfaces
A professional will ask where cracks, offsets or staining appear and how long they have been present. Your dated photos and location notes make that conversation faster and more accurate.
What to look for
Cracks in visible foundation walls or stem walls — note location, approximate length, and whether you can track change over time
Stepping, displacement or separation where foundation meets framing
Efflorescence (white mineral staining) or damp patches on concrete or masonry
Sloping or uneven floors you have noticed inside the home
How to document it
Dated photographs of each area, wide shot plus close-up with a ruler or coin for scale
A simple sketch or marked-up floor plan showing where each observation is
Notes on when you first noticed each condition and whether it has changed
Drainage and moisture
Water management around and under the home is often the first thing an engineer or drainage contractor evaluates. Seasonal patterns matter — a dry-season photo and a wet-season note tell different stories.
What to look for
Standing water, damp soil or musty odors in crawlspace or basement areas
Where downspouts discharge and whether water pools near the foundation
Grading that slopes toward the house rather than away from it
Sump pumps, French drains or other existing drainage equipment — working or not
How to document it
Photos taken after rain, plus notes on how long water persists
Dates of significant rain events when you observed problems
Any receipts or records for past drainage work
Past structural alterations
Removed walls, enlarged openings, added stories or converted spaces change how loads travel through the building. A professional needs to know what was changed, when, and whether permits exist.
What to look for
Walls removed or openings enlarged in any past remodel
Rooms added, stories added, or garage/attic conversions
Visible beams, posts or columns that look retrofitted
Cracks radiating from the corners of modified openings
How to document it
Permit records or finaled inspections for past work, if you have them
Contractor names and approximate dates for past alterations
Any drawings left behind by previous owners or contractors
Retaining walls and slopes
Retaining structures and slope conditions are specialized territory. Documenting what exists — height, material, drainage, lean — helps the right professional scope a site visit.
What to look for
Retaining walls on or near the property — approximate height and material
Walls that lean, bulge, crack or show separated joints
Water weeping through or around retaining walls after rain
Slopes above or below the home and any visible erosion
How to document it
Photos of each wall from several angles, including the top and base
Approximate dimensions paced or measured
Notes on any past wall repairs or rebuilds
Prior repairs and patches
Previous repair attempts — epoxy injections, patching, sistered members, added posts — are critical history. A professional will want to know what was tried and whether it held.
What to look for
Patched or filled cracks, and whether cracks have reappeared through patches
Added posts, jacks, sistered joists or sistered beams
Waterproofing coatings or sealants applied to foundation surfaces
Any engineering reports commissioned by prior owners
How to document it
Invoices, warranties or reports from past repair work
Photos showing patched areas today
Disclosure documents from when you purchased the property
Change over time
A single snapshot rarely tells the story. Notes on seasonal patterns — doors that stick in winter, cracks that widen after rain — give a professional the timeline they cannot observe in one visit.
What to look for
Doors or windows that stick seasonally or newly
Cracks that appear, widen or close with seasons or rain
New sounds, vibrations or movement you have noticed
Changes after nearby construction, earthquakes or heavy rain events
How to document it
A simple dated log of observations, even informal
Repeat photos of the same crack or area taken months apart
Notes correlating changes with weather or nearby work
Age and material uncertainties
Construction era is a research question, not a guess
The home's age and original construction method affect everything a professional considers. Confirm through assessor records, original permits and listing history rather than assuming from style.
Foundation type may be mixed
Older Santa Barbara area homes often combine original perimeter foundations with later additions of different construction. Treat the foundation type as unknown until physically verified in each area.
Unpermitted work is common and usually undocumented
Absence of a permit record does not prove work was never done, and presence of work does not prove it was permitted. Flag mismatches for the professional rather than resolving them yourself.
Soil and geologic conditions are parcel-specific
General area maps cannot tell you the soil behavior under your home. Site-specific geotechnical information comes from a geotechnical professional, not from neighborhood assumptions.

Questions to bring to the professional
Which observations should a structural engineer see first, and which can wait for a general walkthrough?
Does the pattern I documented suggest I need a geotechnical opinion in addition to a structural one?
Which past alterations should I try to find permit records for before the visit?
Are there areas you need opened up or cleared before you can evaluate them?
What monitoring would you recommend between now and any decision about work?
Decision checkpoints
Documentation gathered before scheduling — photos, sketch, change log and records in one place
Red flags reviewed — anything urgent escalated to a qualified on-site professional, not this workbook
Permit records pulled from the correct portal for your jurisdiction (City and County systems are separate)
Professional scope agreed — you know whether you need an engineer, a geotechnical report, a contractor walkthrough, or a combination
Findings and recommendations received in writing before any repair scope is discussed
Who to involve, and when
Licensed structural engineer
Any question about foundation performance, structural alterations, retaining walls, or whether a condition is active. In California, structural engineering is a licensed profession — verify licensure before relying on an opinion.
Geotechnical engineer
When soil, slope or drainage behavior under or around the home is part of the question, especially on hillside or cut-and-fill sites.
Licensed general contractor
To scope and price repair work after an engineer has defined what is needed — not to diagnose the underlying condition.
Architect
When structural work intersects with planned remodels, additions or design changes, so repair scope and design scope are coordinated.
What this workbook does not do
This workbook does not diagnose any condition and cannot tell you whether repair is required — only a qualified professional evaluating your property can do that.
No cost ranges or pricing: repair cost depends entirely on findings that do not exist yet.
No hazard prevalence claims by neighborhood or ZIP code — conditions are parcel-specific.
No permit-path determinations: whether work needs a permit, and from which jurisdiction, is a question for the City or County portal and staff — see the Permit Navigator.
No structural calculations, retrofit designs or product recommendations.
