The conflict is generally between HUD (that typically deems reasonable occupancy to be 2 persons per bedroom) and local jurisdictions and building codes (that calculates reasonable occupancy based on square footage of the bedroom.) As few agents and landlords want to get a Fair Housing violation, they typically choose to abide by the HUD/Fair Housing laws to be on the safe side.
The Virginia Uniform Statewide Building Code contains a minimum occupancy standard which requires at least 50 square feet per person per bedroom. The good news is that to deal with this conflict, they passed a new law (believe it is in effect from July 1, 2013):
§ 36–105.4. Occupancy standards for residential dwelling units.
The owner or managing agent of a residential dwelling unit may develop and implement reasonable occupancy standards restricting the maximum number of occupants permitted to occupy a dwelling unit in accordance with the standard established under federal laws and regulations providing for a maximum of two persons per bedroom. In addition, under the Building Code each bedroom shall contain at least 70 square feet of floor area, and each bedroom occupied by more than one person shall contain at least 50 square feet of floor area for each occupant. An owner or managing agent may restrict the number of occupants in a dwelling unit to two persons per bedroom; however, such restriction shall not be enforceable under the provisions of the Building Code.
The 70 square feet mentioned in the new law is the same as is used by the building code of Fairfax County. The county’s building code says bedrooms must be:
- 70 square feet for one person
- 100 square feet for two people
- 150 square feet for three people
The rules seem straightforward but there are many borderline cases that can make it complicated to know what the exact limit is.
For Fairfax County specifically, they have a page outlining the rules.
The Fairfax County zoning ordinance (Article 2, Part 5) establishes and limits how many persons can live in a single family home. Generally:
- No more than one family, plus two renters, may live in one house.
- Or, no more than four unrelated people may live in one house.
However, the rules define that more than one person can live in a residence:
- One family, which may consist of one person or two or more persons related by blood or marriage with any number of natural children, foster children, step children or adopted children and with not to exceed two roomers or boarders.
- Two single parents or guardians with not more than a total of six of their dependent children, including natural children, foster children, step children or adopted children, functioning as a single housekeeping unit.
- A group of not more than four persons not necessarily related by blood or marriage functioning as a single housekeeping unit.
- A group residential facility (Group Home).
- Any group housekeeping unit which may consist of not more than 10 persons as may be approved by the Board of Zoning Appeals.
- One person or two persons one of whom shall be elderly and/or disabled, and one or both of whom own the dwelling unit, plus one family, which may consist of one person or two or more persons related by blood or marriage, and with any number of natural children, foster children, step children or adopted children.
- A bed and breakfast, as may be approved by the Board of Supervisors, or an accessory dwelling unit subject to a special permit, as may be approved by the Board of Zoning Appeals.
