Outbuilding Inspection
I perform a visual inspection of readily accessible components of detached structures such as garages, sheds, barns, workshops, and guesthouses, in accordance with TREC Standards of Practice.
What I Inspect
An Outbuilding Inspection is similar to a home inspection. I inspect the structural, electrical, plumbing, heating, ventilation, and cooling systems. All aspects of an outbuilding are inspected for safety and hazards.
Outbuildings are anything from shops, storage sheds, boat houses, etc.
Why It Matters
Whether you’re buying, selling, or maintaining a property, this inspection helps you understand the current, observable condition of detached structures so you can make informed decisions and plan accordingly. If an outbuilding is unsafe and is costly in repairs, then why purchase the property? Save money and know what you are buying before you buy.
FAQs
1. Are outbuildings included in a standard home inspection?
Usually, no. Standard home inspections focus on the primary living structure. Small sheds on skids are typically excluded, but larger, permanent structures (like detached garages, guest houses, or barns) are considered add-on services. Since these buildings have their own foundations, roofs, and often electrical sub-panels, they require additional time and expertise to inspect properly.
2. What are you looking for in a detached structure?
We look for the same "Big Four" as a house, but with a focus on how they interact with the land:
-Structural Integrity: Checking for "racking" (leaning), foundation settlement, or rotted sills.
-Electrical Safety: Verifying that sub-panels are properly grounded and that exterior lines (overhead or buried) are safe.
-Pest Activity: Outbuildings are the "front lines" for termites, carpenter ants, and rodents.
-Roofing & Drainage: Ensuring that runoff from the outbuilding isn't flooding the main house's foundation.
3. What if the outbuilding has plumbing or a "granny flat"?
If the structure is a Guest House or ADU (Accessory Dwelling Unit), the inspection becomes more complex. We check the water pressure, water heater safety, and—most importantly—how the waste is handled.
The Big Question: Does it have its own septic tank, or is it tied into the main house? If it’s tied in, we check to see if a "lift pump" is required and if it's functioning correctly.
4. Why is "Fire Separation" a concern for detached garages?
If a garage is used for vehicle storage or as a workshop with flammable materials, we check for proper fire-rated drywall and door seals. Even if it’s detached, if it sits close to the main house (usually within 5–10 feet depending on local code), a fire in the outbuilding can quickly jump to the primary residence.
5. How much does an outbuilding inspection cost in 2026?
The price typically scales with the size and complexity of the building:
-Basic Detached Garage/Shed: $75 – $150
-Large Workshop/Barn (with electric): $150 – $300
-Finished Guest House/ADU: $250 – $450 (effectively a mini-home inspection)
6. Can you inspect agricultural barns or stables?
Yes, but the focus shifts to specialized safety. For horses or livestock, we look for dangerous protrusions, proper ventilation to prevent respiratory issues, and "critter-proof" electrical conduits (to prevent fire caused by animals chewing on wires).
7. Do I really need an inspection for a "simple" shed?
If the shed has a concrete pad or is wired for electricity, the answer is yes. We frequently find "handyman specials" where electrical lines were buried just an inch under the grass or the roof was installed without a drip edge, causing the walls to rot from the top down. An inspection ensures you aren't buying a "tear-down" project.
