McNair is an unincorporated community (a Census-designated place) in Fairfax County, Virginia, and we take portable toilet rental calls for any address in it.

McNair at a Glance
Climate figures: NOAA 1991–2020 normals from the Washington Dc Dulles Ap, VA station, about 3 miles away.
Planning Around the Weather
DOE's Building America map puts Fairfax County in the Mixed-Humid climate region (IECC 2021 zone 4A, PNNL county guide). This region gets both a real summer and a real winter, so a July rental and a January rental need different planning.
Freezing Nights
About 102 nights a year reach 32°F or below, more than most U.S. places in our data, mostly between late fall and early spring. Water-carrying units need a plan from late fall into spring: give your dates when you call and ask how hand-wash water and flush tanks are kept from freezing.
Snow and Access
About 21 inches of snow falls in an average year, less than most U.S. places in our data, usually in a handful of storms. After a storm, clear the route from the road to the units before the next service day so the truck can reach them.
Summer Hot Spells
About 33 days a year reach 90°F, more than most U.S. places in our data; hot spells come and go rather than lasting all summer. If your dates land in a hot spell, ask for an extra service visit on multi-day rentals and keep hand-wash stations topped up.
Job Sites and Home Projects
New Housing
About 26.2% of McNair's housing units were built in 2010 or later (ACS 2020–2024), about 2.3 times the U.S. share of 11.4% and higher than nine in ten U.S. places in our data. Projects that build in phases can move units as each phase finishes; ask for relocation as a service visit when you book. About 6.9% were built in 2020 or later, in the top tenth of U.S. places in our data.
Newer Homes
Half of McNair's housing units were built in 2003 or later (median year built, ACS 2020–2024), newer than nine in ten U.S. places in our data. Newer lots often have a driveway the truck can reach, which makes it easier to place a unit for additions, pools or landscaping work.
Apartments, Townhouses and Rentals
The most common housing type is buildings with five or more units, about 65% of units (higher than nine in ten U.S. places in our data), followed by townhouses and rowhouses at about 29% (ACS 2020–2024). Apartment and condo projects bring larger crews, and a property manager decides where units go. Townhouses and rowhouses share walls and often lack a side yard, so a unit for a renovation may need to sit in a shared driveway or at the curb. About 75% of occupied homes are renter-occupied (ACS; owner share lower than nine in ten U.S. places in our data), so property managers and landlords often book the units for renovations and decide where they stand.
OSHA 29 CFR 1926.51 scales with headcount: 45 workers on an apartment or condo site need 2 toilet seats and 2 urinals, 210 need 5 of each. More on sizing: construction rentals in Virginia.
Events, Weddings and Parties
An all-day festival for 5,000 people over six hours needs 38 units on the PSAI event chart, or 42 to 46 with alcohol (PSAI adds 10–20%). Every cluster of restrooms needs at least 5% accessible units, rounded up; for winter events, clear the route to the ADA unit at full width, not just a footpath.
Cold, not heat, limits the outdoor season: from late fall into spring, ask for a heated restroom trailer or units that do not depend on running water. For a party at an apartment complex or a rented home, the property manager or landlord decides where units can stand. Events in a county park follow the county parks office's rules; ask it what applies before you book. More: event rentals in Virginia and wedding restrooms in Virginia.
Who to Ask About Local Rules
McNair is unincorporated (a Census-designated place), so Fairfax County, not a city hall, handles local roads, parks and events. For an event on public land, or a unit that will stand on a street, sidewalk or in a park, ask the Fairfax County government before you book what applies.
If you rent your home, check with the landlord or property manager before a unit goes on the property. On attached or small multi-unit lots without a driveway, a unit at the curb is a street-use question for the Fairfax County government.
