Investment Property Inspections for 1 to 4 Units

Duplex, triplex, fourplex and single-family rental inspections in Irvine, Costa Mesa and South Orange County. Every unit documented, shared systems reported separately, and termite done in house.

The Short Answer

One building, several homes, one report

An investment property inspection from Trident covers a residential rental with one to four units. We inspect each unit as its own home, then report the roof, foundation, exterior, sewer line and other shared systems at the building level, so you can see what each unit needs and what the whole property needs.

The inspection is led by Certified Master Inspectors and done entirely by our own team. Some inspection companies subcontract parts of the job or pass the termite work along to another firm. At Trident, every inspection is performed by our own certified inspectors, the home inspection and the termite inspection alike, and scheduling is one call or one online booking.

Why It Differs

More units means more of everything, and more that is shared

A fourplex has four kitchens, four sets of bathrooms, often four water heaters and four electrical subpanels. It also has one roof, one foundation and, in many cases, one sewer line carrying everything. A single-family inspection format blurs those together. An investment property report keeps them apart.

Most small multifamily properties also sell with tenants in place. We coordinate access with you or your property manager so each unit can be inspected, and we note anything that occupancy kept out of view.

Every unit, documented on its own

Each unit's kitchen, bathrooms, electrical, water heater and heating and cooling are inspected and reported as that unit's findings, so you can see which units need work and which are ready to rent.

Shared systems, reported separately

The roof, foundation, exterior, common laundry, shared meters or panels and the sewer lateral serve the whole building. We report them as building-level findings, because one repair there touches every unit.

Unit-to-unit conditions noted

We note visible conditions around and between units, such as separation walls, exits and sleeping-room windows, and whether utilities are separately metered or shared, so nothing about the layout is a surprise later.

Negotiation

Findings you can put to work

Findings are organized by priority, so you and your agent can separate safety issues and failing systems from routine maintenance. That is the basis for a clear repair request or credit during your contingency period.

After closing, the same report is a starting list for your capital plan: which unit needs a water heater, how the roof is wearing, what the shared systems will ask of you over the next few years.

Same Visit

Termite and sewer, without a second company

The termite and wood-destroying organism inspection is done in house through Trident Pest Control, our own company licensed by the California Structural Pest Control Board (License #PR8662, Branch 2 and Branch 3), and can be added to the same visit anywhere in Orange County. Why in-house termite matters.

A sewer scope can be added too. On many multi-unit lots one lateral serves every unit, so it is worth seeing before you own it.

Five or more units? That is a commercial assignment with its own scope. See our commercial property inspections. Exchanging into a rental? See 1031 exchange inspections.

FAQs

Investment property inspection questions

It is a home inspection scoped for a residential rental with one to four units: a single-family rental, duplex, triplex or fourplex. Each unit is inspected and documented on its own, and the systems the units share, like the roof, foundation and sewer line, are reported separately. The result is a report you can use to price repairs, plan capital work and decide what to ask the seller for.
The building is inspected the same way, but there is more of it and more of it is shared. Every kitchen, bathroom, water heater, HVAC system and electrical subpanel is a separate set of findings, and we note whether utilities are separately metered or shared. We also note visible conditions between and around the units, such as separation walls, exits and windows in sleeping rooms, so you can see where each unit stands.
Yes. Most small multifamily properties change hands occupied. We coordinate access with you, the listing agent or the property manager so each unit is available during the inspection. Occupied units can limit what is visible, and anything blocked by furniture or stored belongings is noted in the report.
The termite and wood-destroying organism (WDO) inspection can be added to the same visit, and it is done in house through Trident Pest Control, our own company licensed by the California Structural Pest Control Board (License #PR8662, Branch 2 and Branch 3). There is no second company to schedule. In-house termite inspections are available throughout Orange County.
Often, yes. On many small multifamily properties, one sewer lateral can carry the waste from every unit, so a problem in that line affects all of them at once. A standard home inspection cannot see the buried line, and a camera scope can be added to the same visit.
The report sorts findings by priority, so you and your agent can separate safety issues and failing systems from routine maintenance. That gives you a clear basis for a repair request or a credit, and a starting list for your capital plan after closing. What the seller agrees to is up to the negotiation, but you go in knowing what the building needs.
Properties with five or more units are treated as commercial assignments, with a scope set before the inspection. See our commercial property inspections page, or call (949) 294-1188 to talk through the building.
