A Golden Hill or Sherman Heights home inspection looks different from one in a 1990s subdivision. These are some of San Diego’s oldest neighborhoods, packed with 1880s-1920s Victorians and Craftsman bungalows. Expect attention to knob-and-tube wiring, galvanized supply lines, raised foundations with cripple walls, and decades of layered remodels.
Why these neighborhoods need a different eye
Golden Hill and Sherman Heights sit just southeast of downtown, climbing the mesa above the I-5/I-94 split. They were among the first streetcar suburbs in the city, and a remarkable amount of that original housing stock survived. Walk along 24th, 25th, or Fern Street and you’ll see Queen Anne Victorians with turrets, Craftsman bungalows with deep porches, and the occasional Italianate or Folk Victorian cottage. Parts of both areas fall inside or near recognized historic districts, and individual homes may carry their own designations.
That age is the whole story when it comes to inspection. A home built in 1905 has been wired, re-wired, plumbed, re-plumbed, and remodeled by a dozen different hands over 120 years. Some of that work was done well by licensed pros pulling permits. A lot of it was not. The inspector’s job is to read those layers and tell you what’s holding up, what’s a quiet liability, and what needs a specialist before you commit. For a deeper look at how older-home inspections differ, see our guide to historic home inspection in San Diego.
Knob-and-tube and a century of wiring
Homes from this era were often originally wired with knob-and-tube (K&T): individual conductors run through ceramic knobs and tubes, with no grounding conductor. K&T is not automatically dangerous when it’s intact and undisturbed, but the problems are real. It has no ground, it can’t safely handle modern loads, insulation packed against it (a common attic retrofit) traps heat, and a century of brittle cloth insulation tends to crack. Insurers increasingly refuse to write or renew policies on active K&T, which can affect your financing.
What an inspector typically finds in Golden Hill and Sherman Heights:
- Pockets of original K&T still live in attics, basements, and behind walls, even after a partial “rewire”
- Knob-and-tube spliced into modern Romex with no junction box – a hidden fire concern
- Two-prong ungrounded outlets, or three-prong outlets with no actual ground (false grounds)
- Subpanels and panels that have been added piecemeal, sometimes with mixed or obsolete breakers
- Ungrounded knob-and-tube buried under blown-in insulation
A general inspection is visual and non-invasive, so we report what’s accessible and visible. If active K&T or questionable splices show up, the right next step is an evaluation by a licensed electrician who can scope the walls and quote a rewire.
Galvanized pipe and aging plumbing
The plumbing tells the same story. Many of these homes still have galvanized steel supply lines, which corrode from the inside out. Over decades the interior rusts and narrows, so you see weak water pressure, rusty or discolored water at the tap, and pinhole leaks. Galvanized is often partially replaced – copper or PEX up to a point, then original galvanized buried in a wall or under the house.
On the drain side, expect older cast-iron waste lines and, in some homes, original clay sewer laterals running out to the street. Clay and cast iron are exactly where San Diego’s mature trees send roots, so root intrusion, bellies, and cracked sections are common. A visual inspection can flag slow drains and surface clues, but the only way to actually see inside a buried lateral is a camera. If the home is older or the yard has big established trees, we strongly recommend sewer scope inspection as an add-on – a sewer replacement in an old neighborhood is a five-figure surprise you want to find before closing, not after.
Raised foundations and cripple walls
Most homes here sit on raised perimeter foundations over a crawl space, often with short “cripple walls” between the foundation and the floor framing. That construction is normal for the era, but it carries specific risks:
- Unbolted foundations. Many original homes were never bolted to their foundation. In a seismic event, an unbolted, unbraced house can slide off. Foundation bolting and cripple-wall bracing (a seismic retrofit) is one of the highest-value upgrades for an older San Diego home.
- Crawl-space moisture and drainage. These lots are graded on a slope, and water that isn’t directed away ends up under the house, feeding wood rot and conditions that attract pests.
- Settlement and cracking. A century of soil movement shows up as sloping floors, sticking doors, and cracks. Some is cosmetic; some signals real structural movement. Our guide to foundation cracks in San Diego and when to worry walks through the difference.
- Aging concrete or brick footings. Some of the oldest homes have deteriorating concrete or original brick foundations that may need underpinning or replacement.
A home inspector documents the visible condition – sagging, rot, moisture staining, signs of past repair – but a general inspection does not replace a structural engineer. When the crawl space raises serious questions, we’ll tell you to bring one in. Note too that a general inspection is not a termite or wood-destroying-organism (WDO) report; raised foundations and damp crawl spaces are prime WDO territory, so order a separate inspection from a licensed pest operator.
Conversions, additions, and unpermitted work
Golden Hill and Sherman Heights are gentrifying, and that means lots of conversions: large old houses split into duplexes, triplexes, or units; basements and attics turned into living space; garages converted to ADUs; back-house cottages added over the years. Some of this work is permitted and done to code. A surprising amount is not.
Things we routinely catch on converted properties:
- Added bedrooms or units with no permits, undersized egress windows, or low ceiling heights
- Kitchens and bathrooms added without proper venting, plumbing slope, or electrical
- Heating that doesn’t reach converted spaces, or unsafe space-heater workarounds
- Layered roofing – multiple shingle layers over original wood shake – shortening roof life
- Single-pane wood windows that are original (and sometimes historically protected, which limits replacement options)
Unpermitted work matters beyond safety. It can complicate appraisal, insurance, and resale, and a historic designation may restrict what you’re allowed to change. Always verify permit history with the City and ask your agent how any designation affects your plans.
What to do with the report
A thorough buyer’s inspection on a Golden Hill or Sherman Heights home is rarely a simple pass/fail. It’s a map: here’s the original K&T pocket, here’s the galvanized run, here’s the unbolted foundation, here’s the bedroom that was added without a permit. From there you decide what to negotiate, what specialists to call, and what you’re comfortable taking on. Older homes in these neighborhoods can be wonderful and a smart buy – you just want to go in with eyes open.
Remember that disclosure law is on your side. Sellers of one-to-four residential units in California complete a Transfer Disclosure Statement (Civil Code 1102) and a Natural Hazard Disclosure, and “as-is” does not erase a seller’s duty to disclose known material defects. Read those documents alongside your inspection report, and lean on your agent or a real estate attorney for anything legal.
