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.
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.

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.
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.
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.
