O(L)Office, Low-Rise (O(L))

Prince William County, VA · Prince William County Zoning Ordinance (Chapter 32)

O(L), Office Low-Rise District. The O(L) District is intended to implement the community employment center, office, flexible use employment center, and general commercial land use classifications of the Comprehensive Plan. It is designed to provide areas for low- to mid-rise office buildings and research and development facilities, with limited scale retail and institutional uses at a scale serving as a transition between low- to moderate-density residential uses and higher intensity non-residential uses. The purpose of this district is also to promote employment opportunities and to enhance the tax base of Prince William County. Description abridged from Sec. 32-402.10 of the Prince William County Zoning Ordinance -- sentences carrying figures are omitted here so this text can never contradict the standards table, which carries a citation on each value. Read that section for the district's own words in full.

Each row above is the ordinance’s own rule, written out in words and cited to its section. Where a figure depends on what you build (the kind of building, a conventional or cluster subdivision, an interior or corner lot, or the building’s height), each case is its own line; where it depends on the building height, the cited table says how that height is measured.

How complete is this market? Across 147,740 parcels we answer 90.0% of the 6 questions this site is built to answer, each with a source you can check. The rest are shown as “not recorded” rather than filled in — we would rather be short than wrong. A further 3,451 properties inside the county line are zoned by an incorporated town with its own ordinance, not by the county, so this county ordinance does not govern them and they are not counted above or below — which is why we publish this market as Prince William County (excl. incorporated towns). Look one of those up and we will tell you which town governs it.

Permitted uses in O(L)

"Conditional" means the use generally requires a public hearing or special-exception approval — a very different timeline and risk profile from a by-right permit.

This is the zone. What about the parcel?

Zone rules are the starting point — the answer for a specific property also depends on lot size, overlays, existing improvements and site conditions. Run a free address lookup to see what applies to one property.
