One size fits all does not apply to HOA Management.
A multi-story condo building is much more difficult to manage than a community of single family homes or townhomes.
With multi-story condo buildings there are many more regulations and requirements:
Fire inspections
ADA requirements
Emergency lighting systems
Extra Insurance
Etc.
Additionally, in multi-story condo buildings the HOA is responsible for maintaining many more components:
Hot water systems
Sewer pipes
Security systems
Trash chutes
Etc.
More regulations and more components mean a lot more work for Association Managers in multi-story condo buildings.
If your Association Manager mainly manages single family homes or townhomes they are probably not a good match for your multi-story condo building.
