Equipment planning & local resources
A wall head, floor-mounted unit and concealed indoor unit create different access, drainage and air-distribution needs. Compare these approaches using the selected manufacturer’s documents and the project requirements. If the existing ducted system remains, keep that equipment identity with the new room system so the proposal clearly describes what is being replaced and what is being added.
Equipment documents and supply resourcesLake Oswego maintains a Building resource for project information and department contacts. Use the city’s current guidance when the equipment proposal is part of an alteration, and keep the indoor/outdoor schedule connected to that project scope.
Lake Oswego building resourcesOfficial application requirements and approvals come from the responsible jurisdiction. These resources are optional project references, not prerequisites for an equipment quote.
