Calvert County Planning Commission Approves Six Zoning Text Amendments

According to The Southern Maryland Chronicle, the Calvert County Planning Commission on September 16 voted unanimously to forward six zoning text amendments (TAs 2625–2629) to the Board of County Commissioners for final adoption. No members of the public testified on any of the six items. The package addresses implementation defects that surfaced after the county's comprehensive zoning ordinance rewrite took effect March 1, 2025, and follows supplementary amendments adopted in September 2025 and July 2026.

Scope of the amendment package

The proposed changes resolve four categories of post-enforcement friction: sign standards, subdivision timing relief, Critical Area vegetation compliance, and home occupation use classification.

Sign replacement (TA 2625). Existing reader boards at public recreation areas may be replaced in-kind with electronic message centers. New electronic signs are limited to the size authorized under the existing reader board's dimensional restriction. The policy mirrors what the county adopted for places of worship in 2025. County- and county school-owned properties remain exempt from sign rules; privately owned recreation parcels, including the county fairgrounds, fall within the new policy.

Exception lot sunset extension (TA 2626). The deadline for obtaining preliminary approval of "exception lots" extends by one year, from March 1, 2027, to March 1, 2028. Planning staff attributed the delay to weather conditions that have impeded perk testing for affected property owners.

Critical Area replanting ratio (TA 2627). Within the Limited Development Area, the replacement vegetation requirement for clearing between 30% and 50% of a lot's natural vegetation drops from three times to two times the cleared area. The reduced ratio applies only to clearing necessary for a home, driveway, septic system, and minimal yard. Staff confirmed the Critical Area Commission has concurred with the change.

Home occupation kennels (TA 2628). The amendment specifies that in-home daycares and home-based commercial kennels need not operate entirely within an enclosed structure, acknowledging that dogs require outdoor access. In exchange, home occupation kennels must obtain special exception approval from the Board of Appeals, a public process requiring notification of adjacent property owners. Commissioners distinguished home occupation kennels — capped at 600 square feet of indoor space within an occupied residence — from standalone commercial kennel buildings, which remain subject to separate site plan and setback requirements. Zoning rules do not address noise directly; complaints fall under the county's police-enforced noise ordinance or animal control authority.

Farmland preservation housekeeping (TA 2629). Source text for the sixth item was truncated in the available record. Full provisions must be verified against the official text amendment filing before reliance.

Verification checklist

For practitioners monitoring regional land-use and statutory compliance across Maryland:

• Confirm adoption status. All six items require final adoption by the Board of County Commissioners before taking effect. Monitor the BOCC agenda for the scheduled public vote.
• Recalculate Critical Area clearing ratios. Any planned clearing within the Limited Development Area should be re-evaluated under the proposed 2:1 replacement threshold, contingent on final adoption.
• Document existing reader board dimensions. Recreation area operators considering electronic sign replacement should measure and record current reader board face dimensions before commissioning fabrication work.
• Map exception lot deadlines. Property owners pursuing exception lot status should recalibrate permitting timelines to the proposed March 1, 2028 sunset.
• File Board of Appeals notifications early. Prospective home occupation kennel operators should begin adjacent property owner notification in advance of the special exception hearing.
