Gaithersburg Radon Requirements: Local Reference Guide
A careful local-reference guide for Gaithersburg rental and property professionals. City code and rental materials are linked without inferring unverified radon rules.
Reviewed by Daisy Rezende, NRPP Radon Measurement Professional.
Gaithersburg is Smart Home Inspects’ business locality, but that does not make Montgomery County or Rockville radon requirements automatically citywide rules. This page links the City’s current code and rental-housing resources and avoids assigning a radon requirement that has not been independently verified in a current City source.
What has been verified
The City publishes a current code-and-regulations portal, a Chapter 13 landlord-tenant ordinance, and a rental-housing program. Those sources are the appropriate starting point for current local rental and property-management requirements.
The City’s rental-housing page describes a licensing program for rental properties, including apartments and single-family dwellings.
What this page does not infer
A current primary City source establishing a radon-specific multifamily/rental testing interval, ground-contact scope, or mitigation/disclosure rule was not independently verified during this work. This site therefore does not state that one exists or borrow Montgomery County or Rockville details as a substitute.
If a City ordinance, license condition, lease requirement, or current administrative guidance applies to your property, obtain the current official text or advice from the City before acting.
Professional testing remains available
A local requirement is only one reason to test. Property managers, landlords, tenants, and owners can schedule professional measurement to understand a specific property, while keeping legal-compliance decisions separate from the test itself.
Educational information, not legal advice
Local code, agency guidance, and property facts can change how a requirement applies. Review the current official source and seek qualified legal or housing advice for a compliance question.
