Method and sources

Comparable decisions are Board of Zoning Appeals cases that asked to reduce a side yard for an addition, house, garage or deck, located within one mile of the site by straight-line distance. Approved includes approved in part.

Sources are the Board's published minutes and resolutions, Fairfax County, cited by meeting date and page. The county's case record supplies cases decided in years whose minutes UNDA has not yet read.

Conditions are matched by their wording in each resolution, so one resolution can count under several headings. Median resolution: 6 conditions (range 4–21).

Site brief · what it means for this job

Approvals near this lot, and what came with them.

For a side addition 7.1 ft from the line on an R-2 lot of about 30,234 sq. ft.
Summary · written by AI from the records in this brief
A side addition 7.1 ft from the line would sit slightly closer than the typical approval nearby. Of 21 comparable additions, houses, garages and decks within a mile, the Board approved 19, six of them closer to the line than 7.1 ft, at a median of 8.0 ft. On comparable R-2 lots of 20,000–40,000 sq. ft. across the county, all 24 side addition requests were approved, at a median of 9.3 ft. Recent approvals carried about six standard conditions: build to the approved plat and elevations, record the conditions before a building permit, and start within 30 or 36 months. Afterwards, three in four comparable additions had a building permit on the lot within two years, typically about three months after approval. The record shows no denial of a side addition within a mile. It cannot show how the Board would decide a request it has not heard.
