The Birmingham City Commission voted on March 24 to amend the municipal zoning ordinance (Article 4, Section 4.03) to add specific standards for the placement, screening, exhaust direction and maintenance of standby generators on residential lots.
What the ordinance does: The amendment narrows where generators may be located (generally rear yards away from habitable building openings), specifies minimum clearances needed for safe operation and routine maintenance, restricts exhaust outlet orientation so exhaust is directed into open space and not toward habitable windows or entrances, requires permits for new or replacement units, and provides a nonconforming‑use clause with a safety pathway: if the fire marshal deems an existing generator unsafe, it may be required to be relocated or modified.
Why it changed: City staff and the planning board drafted the amendment after the fire and building departments reported repeated carbon-monoxide incidents and other safety calls related to improperly sited residential generators. The planning board reviewed the text and recommended approval to the commission.
Vote and implementation: The commission adopted the ordinance by roll-call vote at the March 24 meeting. Staff said the fire marshal will enforce unsafe installations and the building/zoning staff will administer permits and nonconformance reviews. For existing generators the ordinance allows continued use unless the unit is declared unsafe; in that case the owner must correct the hazard.
What residents should know: Homeowners planning to install or replace a standby generator must obtain city permits and meet the new siting and exhaust-direction rules. City staff advised owners to consult manufacturer specifications and to contact building and fire departments for guidance before installation.
Ending: The amendment becomes the standard for new and replacement residential generators; enforcement will proceed through the building and fire codes and the zoning nonconformity provisions adopted by the commission.
