Homeowner rules in Alexandria, VA

A person last checked these rules on October 20, 2026. This is guidance only, so confirm with Alexandria before you build.

Disclaimer: This is general information, not legal or professional advice for any one property. Codes change. SetbackIQ is not a zoning determination, a permit, or a survey, and it does not replace an architect, engineer, or lawyer. Confirm with your building and zoning offices before you build, buy, or sign a contract.

Permits and building

  • Do I need a permit?Virginia's statewide code sets the building-permit exemptions, but Alexandria's zoning is tight: a shed in a required yard is limited to 100 sq ft (65 sq ft in historic districts), and the city's soil policy asks for a permit on retaining walls from 2 ft. In Old Town and Parker-Gray, the BAR reviews most visible exterior work.
  • Solar panelsA solar energy system is a permitted accessory use (§ 7-101). In the historic districts the BAR reviews panels visible from a public way. An HOA can't ban panels unless its recorded declaration already did.
  • AC units, heat pumps and generatorsAC units, heat pumps and generators may go in side and rear yards only if they stay at or under 55 dBA at every property line. Not in the front yard. The city noise code holds residential property lines to 55 dBA too.
  • EV charging at homeEV charging equipment may stand in any yard if it meets the 55 dBA limit. A Level 2 install needs an electrical permit.
  • Construction hours and noiseConstruction: 7 a.m. to 6 p.m. weekdays, 9 a.m. to 6 p.m. Saturdays, never Sundays. Homeowner power tools: 7 a.m. to 9 p.m. weekdays and 9 a.m. to 9 p.m. weekends.
  • Energy codes, green building and upkeepNew houses and additions follow the 2021 Virginia USBC (in force since January 18, 2024), including its energy provisions. Upkeep of existing homes is enforced by the city's Maintenance Code Division under the Virginia Maintenance Code: structure, heating and cooling, facilities, life safety, trash, tall grass and pests.

Yard and structures

  • Fences and wallsOpen fences up to 4 ft may go in any yard. Open or closed fences up to 6 ft in any yard except the front. Next to a nonresidential lot, side and rear fences may reach 10 ft. The BAR can waive heights in the historic districts.
  • Retaining wallsWalls over 5 ft need a soil report. 2 to 5 ft needs a detail package, a 1,500 psf design or a soil report. Walls up to 2 ft may stand in any yard.
  • Corner sight trianglesOn a corner lot, nothing more than 4 ft above curb grade may sit inside the triangle formed by points 30 ft from the intersecting curb lines. Tree trunks are allowed if branches stay above 8 ft. The BAR can waive this in historic districts.
  • Decks, porches and roof decksEvery deck needs a building permit. Open decks up to 2 ft above grade may sit in any yard except the primary front yard, and a one-story front porch up to 10 ft deep may extend into the front yard if 10 ft of front yard remains.
  • Sheds and garagesIn a required yard, sheds are limited to 100 sq ft total and 10 ft tall (65 sq ft and 8 ft in historic districts). Freestanding garages behind the house have their own size and setback rules.
  • Pools and hot tubsA private swimming pool is a permitted accessory use (§ 7-101). In-ground pools need a soil report or a 1,500 psf design, and pool pumps must meet the 55 dBA limit at the property line and stay out of the front yard.
  • Exterior lighting and light trespassAlexandria's zoning ordinance sets no light-trespass limit for houses. Lighting standards come through site plans and, in the historic districts, BAR review.
  • Driveways and front-yard parkingNo more than 50% of any front, side or rear yard may be used for car parking, driveways included, paved or not (§ 7-1005).
  • Pergolas, play sets and carportsArbors, trellises and pergolas may stand in any yard if no more than 10 ft tall and 80% open. Play equipment may go in any yard except the primary front yard.

Land and environment

  • TreesNo permit is needed to remove a tree on an existing house lot outside an RPA. When work needs a grading plan, the lot must reach 25% tree canopy by planting or preserving trees (§ 7-2200).
  • Floodplains, RPAs, wetlands and stormwaterResource Protection Areas along the city's streams and the Potomac limit new building and paving. SetbackIQ checks the city's RPA map.
  • Steep slopes and problem soilsNew houses always need a sealed soil report, which must flag expansive marine clay. Additions and in-ground pools need a soil report or a 1,500 psf design. Foundation repairs need a soil report.
  • Historic districtsIn Old and Historic Alexandria and Parker-Gray, exterior work visible from a public way needs a BAR certificate of appropriateness, even with no building permit. SetbackIQ checks the city's historic district map.
  • Grading, easements and demolitionErosion and sediment control rules exempt projects disturbing under 2,500 sq ft, unless there's a drainage swale, ditch or storm sewer on the disturbed land or grades exceed 10% (§ 5-4-5). Larger work needs a grading plan, which also triggers the 25% canopy rule.

Living and use

  • RVs, boats and trailers at homeTrailers are banned except one inside an enclosed garage. One unoccupied RV up to 25 ft (R-8, R-12, R-20) or 20 ft (other residential zones) may park behind the front building line.
  • Chickens, bees and urban farmingCity Code § 5-7-2 bans keeping any fowl (chickens, ducks, geese, pigeons) within 200 ft of a home you don't live in, which rules out hens on almost every Alexandria lot. The City Code's animal chapter has no beekeeping rule.
  • Home businessesHome occupations may use up to 25% of the home, with up to two employees, 12 patrons or students a day (two at a time, 7 a.m. to 9 p.m.), no signs and no outside storage.
  • Family child care homesA child or elder care home for one to five people (counting resident children under 12) is a permitted use, registered with the city. Larger homes need further city approval.
  • Occupancy limitsAlexandria's zoning ordinance has no family definition (§ 2-143 is reserved), so zoning sets no cap on unrelated occupants. Space-per-person limits come from the Virginia Maintenance Code.
  • Short-term rentalsEvery short-term rental must be registered with the city. Occupancy is capped at 10 people and at two per bedroom plus two.
