Condo Inspection: What Does an Inspector Actually Check? (2026)

Buying a condo isn't like buying a house. You own the interior of your unit. The HOA owns the building around it. And that distinction changes everything about what an inspection can evaluate.

A lot of first-time condo buyers assume an inspection covers the whole building. It doesn't. Others assume there's not much to inspect because "it's just a condo." Also wrong. Your unit has its own electrical panel, its own plumbing connections, its own HVAC system, its own water heater, its own windows and doors, and its own surfaces that can be hiding moisture damage, mold, or deferred maintenance from the previous owner.

The inspection scope is narrower than a single-family home (you don't own the roof or foundation), but what's inside those walls still matters. And in San Diego's condo market, where units in neighborhoods like Hillcrest, North Park, downtown, Pacific Beach, and Mission Valley range from 1970s construction to brand-new towers, the age and condition of the systems inside your unit can vary enormously from one building to the next.

Here's exactly what gets checked, system by system.

The Electrical System Inside Your Unit

The inspector opens the electrical panel serving your unit and evaluates the capacity (is it sufficient for a modern condo?), the panel type (Federal Pacific and Zinsco panels are safety concerns regardless of building type), the condition of the breakers, the wiring connections, and whether the system is properly grounded.

Beyond the panel, the inspector checks outlets throughout the unit for proper function, polarity, and grounding. GFCI protection is required in bathrooms, kitchens, laundry areas, and within six feet of any water source. According to the National Electrical Code (NEC) requirements outlined by NFPA, GFCI protection standards have expanded significantly over the past two decades, meaning older condos frequently lack protection in locations where current code requires it.

Light switches, ceiling fans, exhaust fans, and hardwired smoke and carbon monoxide detectors are all tested. The inspector notes any outlets that don't work, any circuits that trip during testing, and any visible wiring concerns (exposed wires, improper connections, extension cords being used as permanent wiring).

In older San Diego condos (built before the mid-1980s), aluminum wiring and undersized panels are common findings. These aren't automatic deal-breakers, but they're cost factors a buyer needs to know about.

Plumbing: Supply, Drains, and the Water Heater

Condo plumbing splits into two categories: what's inside your walls (your responsibility) and what's in the common system (the HOA's). The inspector evaluates what serves your unit.

Supply lines. The inspector runs every faucet and checks water pressure. Low pressure can indicate corroded supply lines, a failing pressure regulator, or problems in the building's main supply that affect your unit. The inspector identifies the pipe material where visible (copper, PEX, CPVC, or the older galvanized steel that corrodes from the inside).

Drain lines. Every sink, tub, shower, and toilet is tested for drainage speed. Slow drains across multiple fixtures can indicate a problem in the drain stack serving your unit. A single slow drain is usually a localized clog.

The water heater gets its own evaluation. The inspector checks the age (most tank water heaters last 8 to 12 years), condition, temperature setting, safety devices (temperature and pressure relief valve, expansion tank if required), and venting. In condos with water heaters inside the unit (common in closets or utility areas), proper venting is critical because combustion gases need to exit the building safely.

Toilets are checked for stability (rocking indicates a failed wax seal that can leak), proper flushing, and any signs of past or active leaks at the base or supply connection.

Plumbing Component	What's Checked	Common Condo Findings
Supply lines	Pressure, material, leaks, corrosion	Low pressure from corroded galvanized pipes
Drain lines	Flow speed, material, drain function	Slow drains from shared stack issues
Water heater	Age, condition, temp, safety devices, venting	Units past lifespan, missing expansion tank
Toilets	Stability, flush, base seal, supply line	Rocking (failed wax seal), slow fill
Faucets/fixtures	Function, leaks, hot/cold operation	Dripping faucets, reversed hot/cold
Shut-off valves	Function, accessibility	Seized valves that won't turn

HVAC and Ventilation

Condos use different HVAC configurations depending on the building type and age. Some have individual split systems or package units for each unit. Others have centralized systems where the building provides heating and cooling through shared infrastructure. The inspector evaluates whatever system serves your specific unit.

For units with their own HVAC equipment, the inspector checks the system type, age, and condition, runs the heating and cooling to verify operation, checks the thermostat response, inspects the air handler or indoor unit for leaks and cleanliness, checks accessible ductwork for damage and connections, evaluates the condensate drainage, and notes the filter condition and accessibility.

Ventilation matters more in condos than in most houses. Bathroom exhaust fans are checked for proper operation and exterior termination (a fan that vents into the ceiling cavity or common attic causes moisture problems). Kitchen range hoods are checked for function. In condos without operable windows in every room, adequate mechanical ventilation is especially important.

A common finding in San Diego condos: bathroom exhaust fans that run but don't actually move air to the exterior. The fan motor works, but the ductwork is disconnected, crushed, or was never properly installed. The result is moisture buildup in the bathroom that leads to mold and paint damage over time.

Windows and Doors

Every operable window and exterior door in the unit is checked for function (opens, closes, locks), weather seal condition, glass condition (cracks, failed seals indicated by fogging between panes), frame condition, and water intrusion evidence around the perimeter.

In San Diego coastal condos (Pacific Beach, Ocean Beach, La Jolla, Coronado), salt air corrosion on window hardware and frames is common, especially on aluminum-framed windows. Inland condos may have windows with UV-degraded seals and weatherstripping that's dried out and cracked.

Failed window seals (indicated by condensation or hazing between dual-pane glass) mean the insulating gas has escaped and the window's thermal performance is reduced. Individual window replacement in a condo typically costs $300 to $800 per window depending on size and type.

Sliding glass doors (common in San Diego condos with balconies or patios) get special attention. The track, rollers, lock, and weatherseal are all checked. Worn rollers and damaged tracks are among the most common sliding door findings.

Ceilings, Walls, and Floors

These are the surfaces that tell stories about what's happening inside the building assembly.

Ceilings are checked for water stains (indicating leaks from the unit above, the roof, or plumbing within the ceiling), cracks (which can indicate structural movement or normal settling), and any sagging or soft areas.

Walls are evaluated for cracking patterns, moisture evidence, and general condition. The inspector uses moisture meters on walls that show staining or other indicators of possible water intrusion. In condos with shared walls, moisture from a neighbor's plumbing leak can migrate through the wall assembly and affect your unit.

Floors are checked for levelness (significant slopes can indicate structural movement), soft spots (which can indicate subfloor damage from moisture), and condition of the finished flooring.

Balconies and Patios

If your condo has a balcony or patio, the inspector evaluates the surface condition, drainage (water should flow away from the building, not toward it), railing stability and height (42 inches minimum for safety), any visible structural concerns like cracking or spalling, and the waterproofing at the balcony-to-building transition.

Balcony condition is especially important in California. Under SB 326, condominium associations are required to have exterior elevated elements (balconies, walkways, stairs) inspected by a licensed architect or structural engineer. The condo inspection checks the condition of your unit's balcony from a general home inspection perspective, but the SB 326 inspection is a separate, building-wide requirement that the HOA is responsible for completing.

Kitchen and Bathroom Specifics

Kitchen. The inspector tests all built-in appliances (dishwasher, disposal, range/oven, microwave, range hood). They check the sink and faucet for leaks and function. They verify GFCI protection on countertop outlets. They check under the sink for moisture, leaks, and proper drain connections.

Bathrooms. The inspector checks the shower/tub for function and proper drainage. They test the exhaust fan. They check the toilet, sink, and faucet. They look for signs of past or active leaks around the tub/shower surround, at the base of the toilet, and under the vanity. They check grout and caulk condition (failed grout and caulk are the most common pathways for water to get behind shower walls and cause concealed damage).

Laundry and Built-In Appliances

If the unit has in-unit laundry (washer and dryer connections or a stacked unit), the inspector checks the supply connections, drain line, electrical or gas connection, and venting. Dryer venting in condos is especially important because improper or disconnected dryer vents are a leading cause of residential fires, and in a multi-unit building the consequences are amplified.

The inspector also notes whether the laundry drain has a proper P-trap and whether the supply valves are accessible and functional. In older San Diego condos, laundry areas that were added during a renovation sometimes have supply connections that aren't properly supported, drain connections that are undersized, or venting that terminates in a wall cavity rather than the exterior.

Built-in appliances beyond the kitchen (garbage disposals, bathroom vent fans, ceiling fans, and any integrated air filtration or water filtration systems) are tested for basic function and noted in the report. The inspector isn't evaluating appliance performance in detail, but they're confirming things work, identifying safety concerns, and noting units that appear to be at or past their expected service life.

What the Condo Inspection Doesn't Cover

Understanding the limits is just as important as understanding the scope.

A condo inspection does not cover the building's roof (HOA responsibility), the building's foundation and structural system (HOA), common area plumbing and electrical (HOA), elevators (HOA), the parking structure (HOA), shared HVAC systems (HOA), or the building's exterior envelope (HOA).

The inspector evaluates your unit. The building-level systems are the HOA's domain. Whether the HOA is actually maintaining them well is a separate question that requires reviewing HOA documents, reserve studies, and maintenance records, not an inspection of your unit.

How We Approach Condo Inspections at 360

We inspect condos across San Diego County, from high-rises in downtown and the Gaslamp to townhome-style units in Mira Mesa and Chula Vista. The approach is different from a single-family home because the scope is different, and we make sure buyers understand what we're evaluating and what falls outside our reach.

We check every system inside your unit, document findings with photos, and flag anything that needs attention or further evaluation. When we identify concerns that suggest building-level problems (moisture from above, plumbing noise from shared stacks, structural cracking patterns), we note it and recommend reviewing the HOA's maintenance records and reserve study for context.

Frequently Asked Questions About Condo Inspections

Q: What does a condo inspection include?

A condo inspection evaluates the electrical system, plumbing, HVAC, water heater, windows, doors, ceilings, walls, floors, kitchen appliances, bathrooms, and any balcony or patio within your unit. It does not cover building-level systems like the roof, foundation, elevators, or common area infrastructure, which are the HOA's responsibility.

Q: Is a condo inspection different from a house inspection?

Yes. A condo inspection focuses on the interior of your unit and the systems that serve it directly. A house inspection also covers the roof, foundation, exterior, site drainage, and all building systems. The scope is narrower for a condo because the building's major systems are owned and maintained by the HOA.

Q: How much does a condo inspection cost in San Diego?

Most condo inspections in San Diego run $300 to $500 depending on the unit size and complexity. Larger units, penthouses, or townhome-style condos may cost more. This is less than a standard single-family home inspection because the scope is narrower.

Q: Should I get a condo inspection before buying?

Yes. Even though you don't own the building, you own everything inside your unit. Plumbing leaks, electrical problems, HVAC issues, water damage, and deferred maintenance inside the unit are your financial responsibility after closing.

Q: Does the inspector check the building's common areas?

No. Common areas, the building exterior, the roof, the foundation, shared plumbing, and elevators are outside the scope of a unit inspection. Those are maintained by the HOA. You should review the HOA's reserve study and maintenance records separately.

Q: What are the most common condo inspection findings in San Diego?

Water heaters past their useful life (8 to 12 years), bathroom exhaust fans that don't vent to the exterior, low water pressure from corroded supply lines, failed window seals (fogging between panes), GFCI protection missing in required locations, and moisture evidence around showers and tubs from failed grout or caulk.

Q: Can a condo inspection find mold?

The inspection can identify moisture conditions that suggest possible mold growth (water stains, elevated moisture readings, musty odors). Confirming mold presence and type requires separate mold testing with air and surface sampling.

Q: Does the inspector check the condo's electrical panel?

Yes. The electrical panel serving your unit is evaluated for capacity, condition, breaker type, grounding, and any visible safety concerns. This is one of the most important components of a condo inspection, especially in older buildings.

Q: What should I do if the inspection finds problems?

Use the findings to negotiate with the seller. You can request repairs, negotiate a price credit, or factor repair costs into your purchasing budget. For significant findings (electrical panel replacement, plumbing repairs, water damage remediation), get quotes from licensed contractors to understand the actual costs.

Q: How long does a condo inspection take?

Most condo inspections take 1.5 to 2.5 hours depending on unit size. Larger units or townhome-style condos may take longer. The inspector needs access to the electrical panel, water heater, HVAC equipment, and all rooms.

What It Comes Down To

A condo inspection scope is smaller than a house inspection. But "smaller" doesn't mean "less important." Everything inside those walls is yours after closing. The plumbing, the wiring, the water heater, the windows, the balcony condition, the moisture you can't see behind the shower surround. All of it.

The inspection tells you what you're buying at the system level, not just the cosmetic level. And in a market where San Diego condos routinely sell for $400,000 to $800,000 or more, spending $300 to $500 to know what's inside before you commit is basic due diligence.

Cost estimates in this article reflect general ranges for the San Diego County market as of 2026 and will vary based on unit size, building age, and specific conditions. Always confirm pricing with your inspector before scheduling.
