Crews tore down a house on Northeast 29th Avenue and replaced it with a much larger house. After that replacement, crews tore down the neighboring house, too. (Casey Parks/The Oregonian)

Some infill developers have taken to tearing down the majority of a house but leaving small parts standing. As far as city planners are concerned, that’s a remodel, not a demolition.

Neighbors have also raised concerns about asbestos being released during demolitions without proper precautions. The Bureau of Development Services may require developers seeking a demolition permit to acknowledge that they have to meet state asbestos regulations.
