This project checklist identifies general planning issues to discuss with the local office. The linked city resources provide starting points; they do not establish every project-specific requirement.

Permit takeaway

Raleigh equipment replacements can require mechanical and electrical review even when the new unit occupies the same general location as the old equipment.

Zoning and placement

Exterior condensers, generator or fuel equipment, rooftop units, noise, screening, flood elevation, historic review, and clearance from property lines or openings can affect equipment placement.

Building and trade review

Mechanical review commonly checks equipment sizing, energy efficiency, refrigerant lines, condensate disposal, duct sealing, combustion air, venting, fuel-gas testing, disconnects, service receptacles, and ventilation discharge.
