An ADU Home Inspection evaluates the condition, safety, and major systems of an accessory dwelling unit before a purchase, sale, or renovation. It can help homeowners and buyers identify hidden problems, understand potential repair needs, and make more informed property decisions.
What is an ADU?
An accessory dwelling unit is another residential structure built on the same lot as the existing residential building. ADUs may come with a cooking facility, toilet, sleeping area, entrance, and other facilities.
The ADU could either be built separately from the main structure or attached to it. The most common uses for an ADU include guest accommodations, a home office, and a rental unit. Since there are some differences between an ADU and the main structure in terms of construction, systems, and maintenance, the condition of an ADU is relevant.
Types of Accessory Dwelling Units (ADUs)
Detached ADUs
This type of ADU refers to a different structure that is located elsewhere on the property. The inspection can include evaluation of the foundation, exterior, utility lines, drainage, roof, and the connection between the ADU and the main property.
Attached ADUs
This ADU type is connected to the main home by a wall or some other structural elements. The inspection may concentrate on shared facilities, potential moisture issues, electrical connections, and separation of the two units.
Garage Conversion ADUs
The garage conversion ADU requires many renovations to the original structure. Inspection can reveal various problems related to insulation, ventilation, electrical, plumbing, foundations, and the conversion process.
Junior ADUs
The junior ADU refers to the smaller living space that is usually formed inside or near some other existing dwelling. The inspection regulations for such units will vary according to their construction process and location.
Why Is ADU Inspection Needed?
Accessory dwelling unit inspection services help detect any potential safety hazards. Some issues, like improper wiring or plumbing, lack of adequate electrical components, and deterioration of materials, might exist even if the apartment seems to be well-maintained. Water leakage through the roof, windows, plumbing elements, or foundation will also become a problem, causing decay and a mold-like environment. Maintenance problems and possible costs associated with them can be revealed during inspection too.
The ADUs were constructed some time ago, and those that were converted to the living area require special attention since their construction might not correspond to the recent standards. For the buyers who are going to purchase ADU housing, an inspection is a good opportunity to learn more about it.
Standard Inspection vs ADU Inspection
The ADU is not necessarily supposed to be left out just because there is an inspection done on the main house. Each of the structures may contain electrical, plumbing, roofing, foundation, drainage, and heating systems separately
Why an ADU Inspection is Not the Same as a Regular Home Inspection
While a standard home inspection tends to check only the primary house and its accessible systems, an ADU inspection checks on the added living quarters.
This becomes necessary, especially when you are dealing with a garage conversion, older addition, detached unit, or any ADU that may have undergone renovations. This becomes even more helpful, especially in Los Angeles.
ADU Inspection Checklist: What is Inspected During an ADU Inspection?
An extensive ADU inspection checklist may depend on various factors such as the structure, age, accessibility, and the purpose of the inspection. Some of the common items include:
Electricity System
An ADU inspector inspects any visible part of the electrical system in terms of damage, potential hazards, and possible issues that may impact safety.
Plumbing System
Any visible part of the plumbing system, including supply pipes, faucets, drains, water heaters, and others are inspected.
Sewer and Drainage
A sewer inspection may reveal blockages, damaged sewer lines, roots, or other issues when further tests are needed. The surface drainage from the ADU is also included.
Foundation and Structural
There is a foundation inspection to detect visible cracks, settling issues, structural deterioration, or other conditions. The inspector will also assess structural elements for any damage.
Roof and Attic
The roof and accessible parts of the attic are inspected for any deterioration, damage, ventilation, moisture presence, and other conditions that can affect the structure.
Moisture, Water Damage, and Mold-Like Conditions
Visible presence of moisture, water stains, moisture on the surfaces, and other conditions will be identified during the inspection.
Exterior and Drainage
Exterior walls, doors, windows, grading, drainage, walkways, and any other accessible exterior features are inspected for any issues that might cause potential problems with water infiltration or damage.
How Much Does an ADU Inspection Cost in Los Angeles?
The amount you will pay for an ADU inspection in Los Angeles is not a flat-rate fee but varies depending on a few things. ADU size, age, condition, accessibility, and whether the ADU is attached or detached will all be factors in determining your ADU inspection cost.
The type of inspection will make a difference, too. Any extra services such as sewer line evaluation or structural inspection testing may add to the total cost.
Choosing An ADU Home Inspection Company in Los Angeles
When selecting an inspection company to perform ADU home inspection services, it is vital to choose an inspection firm that has experience with both ADUs and general home inspections. Companies with experience in working on old homes, garages, and addition structures could have more value than those without.
An efficient inspection company needs to deliver a report that explains the condition of the house effectively and without using technical jargon that would make the findings hard to understand. The inspector must know about the quality of Los Angeles homes.
It is recommended that when buying or selling your property that has ADUs, you arrange an inspection before finalizing the deal.
Frequently Asked Questions
What does an ADU inspection include?
An ADU inspection typically covers accessible structural, electrical, plumbing, roofing, exterior, drainage, and moisture-related conditions. The exact scope depends on the property and inspection agreement.
Should I buy a home with an unpermitted ADU?
An unpermitted ADU does not automatically mean you should reject the property, but it creates additional risks. Buyers should understand the unit’s condition, permitting status, potential compliance issues, and possible costs before purchasing.
Can a home inspection identify an unpermitted ADU?
An inspector may notice signs that a structure or conversion appears inconsistent with the property’s original configuration, but a home inspection is not a permit verification service. Buyers should contact the appropriate local authority to confirm permitting and legal status.
How long does an inspection take and what does it cost?
Inspection time and cost vary according to the ADU’s size, condition, accessibility, construction type, and scope. Additional testing can also increase the time and price.
What happens during an ADU home inspection?
The inspector visually evaluates accessible components and systems, documents significant findings, and typically provides a report describing observed conditions and recommended follow-up where appropriate.
Should I inspect an ADU before selling my home?
Yes. A pre-sale inspection can help identify repair or maintenance concerns before listing the property. Addressing significant issues early can reduce surprises during negotiations and give sellers a clearer understanding of the property’s condition.
