Online Building and Land Development Information

Looking for computerized land development information? Customers looking for information about building construction, site development or a zoning project can search for records in one of the following systems.


The Land Development Information History (LDIH) system consolidates building, site, zoning and complaint information from numerous county systems into a single repository. LDIH provides an overall search on land development records. The easy-to-use search features make this tool the simplest and quickest method to retrieve site- and building-related information. LDIH data is updated weekly on Friday evenings.


The Fairfax Inspections Database Online (FIDO) system provides a more specific search on building-related records, including permitting, plan review, inspection and complaints management services. FIDO also includes a Web portal that enables customers to process permit applications online and obtain real-time information.


The LDSNet  system provides a more specific search on zoning and site-related records. In addition, this database also contains bonding and escrow information as well as building permits issued information. The LDSNet system has multiple search function capabilities for plans, bonding, escrows, inspections and building permits. There are also capabilites to search by addresses and magisterial districts.

If you require a certified record or cannot find the information you need, please contact our FOIA office at 703-324-1833, TTY 711.
