Hi @daisy4,
Thank you for your question about attaching deck framing to a concrete porch.
There are a few ways this can be done, however, the specifics of your deck will likely determine the best method. If you could share some of the specifics of your plan, I'd be happy to point you towards your best option.
As deck framing can't sit directly on the concrete, raising it with pedestal feet or packers is essential. You can then use things like angle brackets or stirrups to connect the framing to the concrete.
Let me know of any further details, I am happy to help further if required.
