R-MHResidential Mobile Home (R-MH)

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

Residential Mobile Home (R-MH). The general purpose and intent of the RMH, Residential Mobile Home District is to promote moderate priced housing opportunities by allowing development of mobile home subdivisions or parks within the suburban residential low and suburban residential medium land use classifications of the Comprehensive Plan in accordance with sound planning principles, while preventing detrimental effects to the use or development of adjacent properties. Description abridged from Sec. 32-303.61 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 R-MH

AllowedMobile Home / Manufactured
In approved parks or lots. (Sec. 32-303.62)
Not AllowedSTR - Short-Term Rentals
Prince William's Zoning Ordinance has no 'short-term rental' use -- the phrase does not appear in Chapter 32. What it has is a bed and breakfast inn, defined in Part 100 and expressly available 'for transient occupancy', with standards at Sec. 32-300.15; and 'short-term lodging', which Part 100 defines narrowly as time-share units. (A lodging house is NOT a route to it -- Part 100 excludes 'accommodations used for transient occupancy' from that term.) Neither appears in this district's permitted, secondary or special use sections, and a use not specified in a zoning district is prohibited there (Sec. 32-200.03). (Sec. 32-200.03)
Not AllowedCommercial
Not listed among this district's permitted, secondary or special uses. A use not specified in a zoning district is prohibited there (Sec. 32-200.03).

"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.
