Proposed Amendments to Appendix Q (Land Development Services Fee Schedule) of the Code of the County of Fairfax, Virginia Regarding Adjustment of the Fees Charged by Land Development Services for Plan Review, Permits, and Inspection
The Department of Land Development Services (LDS) proposes adjusting Appendix Q (Land Development Services Fee Schedule) for plan review, permits, and inspection services to meet the Board’s direction for approximately 100% cost recovery through plan review, permits, and inspection fee revenue. Adjustments to Appendix Q will also cover enhancements for customer service. Any proposed fee increases approved by the Board of Supervisors would be effective on July 1, 2026 (FY 2027).
Public hearings have been scheduled regarding proposed changes to that include a 5% increase across most of the fee schedule. The proposed 5% increase does not apply to elevator permits and inspections, the technology surcharge percentage, code academy levy percentage or zero fee applications – these will remain unchanged. LDS’s applications and services which currently do not require a fee will also remain unchanged. The amendment also proposes minor adjustments to the 5% increase for smaller fees where the 5% increase does not round to a penny. The amendment further proposes a fifty percent (50%) increase in fees related to major Water Quality Impact Assessments (WQIA) for bonded and non-bonded lots and exceptions under Article 6 of the Chesapeake Bay Preservation Ordinance (Chapter 118 of County Code) which require a public hearing to reflect the significant staff time associated therewith.
The proposed 5% increase addresses inflation as directed by the Board and noted above and ensures that service levels do not decrease as costs increase. Notwithstanding, LDS continues to implement enhancements to the development process, which directly benefit applicants including:

Amendment to the Code of the County of Fairfax, Virginia (County Code) to adopt new Chapter 124.1 (Erosion and Stormwater Management Ordinance) and repeal Chapter 104 (Erosion and Sedimentation Control) and Chapter 124 (Stormwater Management Ordinance) in their entirety.
The amendment consolidates the existing erosion and sediment control requirements, stormwater management requirements, and provisions to satisfy the County’s state-issued municipal separate storm sewer permit into a single ordinance. The ordinance clarifies program requirements, eliminates redundancies, and corrects inconsistencies between the existing ordinances. There are no substantive changes to existing erosion and sediment control minimum standards or to the post-construction stormwater management technical criteria. The ordinance requires all land-disturbing activities equal to or greater than 2,500 square feet to provide erosion and sediment control, water quantity control, and water quality control. The Board did not adopt the optional provision that would have exempted land-disturbing activity equal to or greater than 2,500 square feet and less than one acre for construction of single-family detached residential structures not part of a common plan of development or sale meeting certain criteria from providing water quality control.
