Who Reads the Report When 58,148 Irving Households Rent?
In Irving, 58,148 of the occupied homes are rented and 36,104 are owned. A foundation problem in a rented house is rarely settled by one person: the occupant sees the crack, a landlord or property manager pays, and sometimes an insurer or an agent reads the result. The HGS report is written for that chain, with findings stated once and in plain words.
Irving's median home dates from 1986, and 37,637 of its 101,312 homes, 37%, were built before 1980, the second highest share on this site after Cleburne. 26,046 homes came from the 1960s and 1970s alone. That is a large number of houses old enough to have had one round of repairs and a second round of drainage changes around the house.
The Census also counts 1,728 manufactured homes, 1.7% of housing units, and 255,036 residents in all. In a city this size the inspection request rarely comes from the same kind of household twice, which is why the report is written to stand alone.
What Does the Airport Rain Record Say About an Irving House Built in the 1970s?
Irving shares the Dallas-Fort Worth International Airport record with Grapevine and Lewisville. That station gives 37.0 inches of rain in a normal year, with May the wettest month at 4.78 inches and July the driest at 2.08. A house built in 1975 has been through more than forty of those years, and the report records what the drainage around it does now.
What Does Dallas County's 63.9 Percent Rating Add for Irving Landlords and Agents?
Dallas County is rated 63.9 percent high or very high shrink-swell by the USDA soil survey, and 44.4 percent of rated acres are in the very high class. Houston Black (67,795 acres), Trinity and Heiden lead the list. For an agent or landlord the number is background: it says the clay is active on average, and the report says what this house shows.
The Drought Monitor shows 61 of 262 weeks since October 12, 2021 with some of Dallas County in severe drought or worse, and 68.52 percent in that class on the map dated October 13, 2026. Whatever the county map shows, the engineer records what is in this house.

What Is Different About Working With Landlords and Agents?
The report is a standalone document. A property manager who forwards it to an owner does not have to explain it, and an agent can attach it to a listing file. It gives the observed conditions, the permitting that would apply to indicated repair work, and the drainage items, in that order.
A fire in a rental is a separate question from a foundation question, and the firm handles those through its structure-fire evaluation service. The two services use the same report format.
Irving's 101,312 homes make it the fourth largest of the eleven cities by housing units, and 37,637 of them were built before 1980. The older ones are the more likely to have been altered by a prior owner, and a rental changes hands often enough that the history is thin. The report starts from what the engineer can see on the day and does not guess at what no one wrote down.
“Very professional and knowledgeable. Was the reason my client purchased a home with confidence. 10/10 recommend!”

What Can an Agent or Landlord Do With an Irving Report?
Hand it to whoever has to decide. Nobody reading it is being sold work, because it carries no repair price and the firm repairs nothing. Details are on the foundation inspection page, and requests start at the request form.
