Gaithersburg, MD Home Business: Customer Traffic Restrictions (2026)

Montgomery County Zoning Ordinance Chapter 59 sets specific client visit limits for each home occupation tier, with the explicit goal of ensuring that home-based business activity does not transform the traffic character of residential streets. The traffic limits are enforced as weekly maximums, and the manner in which visits are distributed throughout the week matters for compliance purposes. A No-Impact Home Occupation allows a maximum of 5 client, customer, or patient visits per week. This limit is designed for businesses that are primarily office-based with occasional in-person meetings, such as a consultant meeting a client at home, a tutor seeing one student per day, or a therapist conducting a few weekly sessions. The visits should be spread throughout the week rather than scheduled back-to-back on a single day, as concentrating all 5 visits on a Saturday afternoon would create a noticeable traffic pattern inconsistent with residential character. A Low-Impact Home Occupation allows up to 20 client visits per week, accommodating businesses with more regular client interaction such as small-scale professional services (bookkeeping, counseling, physical therapy), music or art instruction, or personal services. At 20 visits per week across 5 to 6 operating days, this averages 3 to 4 visits per day, which is generally consistent with the level of visitor activity seen at any active household. Parking management becomes more important at this tier, and clients should be directed to park on the street without blocking neighbors' driveways or mailboxes, or to use the home occupation's own driveway. A Major Home Occupation has no preset traffic limit. Instead, the county Hearing Examiner evaluates the proposed business activity during the Conditional Use hearing and sets specific traffic conditions tailored to the location, street width, neighborhood density, and type of business. Conditions commonly include maximum daily or weekly client visits, restricted hours of client access (for example, no client visits before 8 AM or after 8 PM), required off-street parking (one or more spaces on the property), restrictions on delivery vehicle size (no tractor-trailers), and designated delivery windows. The Hearing Examiner may also require a traffic impact analysis for high-volume proposals. Across all tiers, the fundamental standard is that the traffic generated by the home occupation must not be substantially different from normal residential traffic. Code enforcement typically becomes involved when neighbors file complaints about unusual traffic volumes, unfamiliar vehicles, double-parking, blocked driveways, or commercial truck activity. A sustained pattern of complaints may result in investigation, reclassification to a higher tier (requiring registration or Conditional Use approval), or revocation of the home occupation if violations continue. Delivery restrictions apply to all tiers: inventory deliveries by tractor-trailer or large box truck are prohibited, and deliveries should be limited to what a standard residential delivery service (USPS, UPS, FedEx) would handle.
