Foundation Problems in a Rental Property: What Owners and Property Managers Should Document

A tenant texts you a photo of a crack running across the living room wall. Or the property manager mentions that the back door has started sticking and a bedroom floor feels off. When the house is someone else’s home, a possible foundation problem comes with an extra layer: a record you share with the person living there.

This post is for owners and property managers of rental homes and small rental buildings in La Jolla. It covers what to write down, how entry for an inspection fits into California’s notice rules, and what records are worth keeping once someone has looked at the building.

This is not legal advice. We’re a foundation and structural repair company, not lawyers. We quote a few California statutes so you know they exist. What they mean for your lease, your tenant, or your situation is a question for a California attorney or your property management counsel.

Why the record matters

California’s Civil Code sets a baseline duty for residential rentals. Section 1941 says the lessor “must, in the absence of an agreement to the contrary, put it into a condition fit for such occupation, and repair all subsequent dilapidations thereof, which render it untenantable.” Section 1941.1 then lists characteristics a dwelling is expected to have. Two of them touch the building shell: “Effective waterproofing and weather protection of roof and exterior walls, including unbroken windows and doors,” and “Floors, stairways, and railings maintained in good repair.”

We aren’t telling you whether any crack or sloped floor reaches those standards. That’s not our call to make, and it may not be anyone’s call until the condition has been evaluated. The practical point is simpler: when a tenant reports something structural, a clear, dated record of what was reported, what you did, and what the professionals found protects everyone’s understanding of the facts.

For the separate job of documenting foundation history before a sale, see our seller foundation documentation checklist. This post is about the ongoing record while the property is occupied.

Step 1: Log the report the day it comes in

Write down the tenant’s report as close to their words as you can. Note:

  • Date and time of the report and how it came in (text, email, portal, phone).
  • What they described: crack location and direction, doors or windows sticking, floors sloping or bouncing, gaps at trim, water at the base of a wall.
  • When they first noticed it, and whether it seems to be changing.
  • Any photos they sent, saved with the original date.
  • Anything urgent: a door that won’t open, glass that cracked, a sudden new gap, or water coming in. Those deserve faster attention than a hairline crack that’s been there for years.

Reply in writing to confirm you received it. A short note saying you’ve logged it and will schedule a look is enough. Keep the thread.

Step 2: Schedule entry the right way

A foundation evaluation can need someone inside the unit and, on a raised foundation, in the crawl space. Civil Code Section 1954 lists the reasons a landlord may enter, including “To make necessary or agreed repairs, decorations, alterations or improvements, supply necessary or agreed services, or exhibit the dwelling unit to prospective or actual purchasers, mortgagees, tenants, workers, or contractors.”

The same section says the landlord “shall give the tenant reasonable notice in writing of his or her intent to enter and enter only during normal business hours. The notice shall include the date, approximate time, and purpose of the entry.” It adds that “Twenty-four hours shall be presumed to be reasonable notice in absence of evidence to the contrary,” with different timing when the notice is mailed. It also says “The landlord may not abuse the right of access or use it to harass the tenant.”

There are exceptions in the statute, including emergencies and tenant consent at the time of entry. How they apply to you is a legal question. What we’d suggest as practice:

  • Put the date, time window, and purpose (for example, a foundation and structural evaluation) in the written notice, and keep a copy.
  • Tell the tenant who is coming (your company, an engineer, a contractor) and roughly how long it may take.
  • Ask whether they’ve noticed anything else since the first report, so the evaluator sees it.
  • If an engineer’s visit and a contractor’s visit are separate, each one is a separate entry to schedule.

Step 3: Document the condition yourself before the visit

If you or your manager are already entering with proper notice, take your own baseline record:

  1. Wide and close photos of every crack or gap, with something for scale. Our crack monitoring guide explains simple ways to track width and length over time.
  2. Doors and windows: which ones stick, and where the gap is uneven.
  3. Floors: where they slope or feel soft. A marble or a level reading noted on a sketch is enough.
  4. Exterior: cracks in the foundation, stucco, or steps; downspouts that discharge next to the house; soil washed out or piled against the wall.
  5. Crawl space hatch, if there is one: whether it’s reachable, and anything visible from the opening. Don’t crawl in unless you’re equipped for it.

Date every photo and note who took it. The HUD Residential Rehabilitation Inspection Guide tells inspectors to “Determine the source of any moisture that may be present.” Water can be part of a foundation story, so note any moisture you see, even if it seems unrelated.

Step 4: Get the right kind of evaluation

Not every report needs the same visit. Our foundation inspection and structural inspection pages explain the difference in scope. If the picture points to settlement, soils, or framing that needs design, a structural engineer may be the right first call. We work with verified contractors and coordinate with licensed engineers as needed.

What to ask for in writing, whoever comes out:

  • What they looked at and what they couldn’t reach.
  • What they observed, in plain language.
  • Whether anything appears to need prompt attention, and why.
  • What further evaluation, if any, they recommend.

Keep each party’s report as its own document, even when the visits happen on the same day.

Step 5: Keep the paper trail organized

Once there’s a finding, the useful file looks like this:

  • Tenant report and your acknowledgment.
  • Entry notices, with dates.
  • Your baseline photos and any later follow-up photos.
  • Evaluation reports from each party, unedited.
  • Bids or proposals for any work, and what was chosen.
  • Permit records, if the work needed a permit. The City’s Development Services records can show what was permitted at the address; our permit basics post explains the process.
  • Completion notes and final inspection, if any.
  • Communication with the tenant about scheduling and any disruption during the work.

If the property changes hands later, this file becomes part of the history a buyer will ask about. Our buyer’s foundation inspection guide shows what that side of the table looks for.

What not to do

  • Don’t patch over a crack before it’s been looked at. Fresh paint erases the record of width and pattern.
  • Don’t describe a condition as settled, cosmetic, or safe in writing to a tenant unless a qualified evaluator said so, and then quote them.
  • Don’t treat this post as a substitute for legal advice about notices, rent, repairs, or tenant rights. Ask a California attorney.

Cost factors, not prices

We don’t publish prices. Things that shape the effort and cost of a rental foundation evaluation include: how many units and how much floor area are involved; whether a crawl space is accessible; whether occupied rooms need furniture moved; how many separate visits (inspection, engineer, contractor) are needed; whether drainage, plumbing, or soils questions come up; and whether permits and engineered plans are required for any repair.

Where we fit

We’re a foundation and structural repair company serving La Jolla citywide. We can visit with proper notice arranged by you, look at what the tenant reported, and explain what we see in writing. We aren’t engineers, and we aren’t lawyers. When a condition needs structural design or soils input, we coordinate with licensed engineers as needed. This post is general education, not an assessment of any property and not legal advice.
