Seismic retrofit for added rooms in North Hills
Aspenwell Construction checks how a later room addition on a North Hills house meets the original frame, then plans bolting and bracing for LADBS.
My house had a room built onto the back at some point, so does that part need bolting too? For a North Hills home the short answer is that both parts need a look, and the seam between them deserves a careful look of its own. An addition may rest on its own footing, at a different height, with framing that meets the old wall only at a few nails. We trace each piece back to the concrete.
Where the old house meets the new room
Along the joint, we look for a continuous footing or two separate ones with a crack between them. In the crawlspace, the sill of each part gets its own bolt count, and any cripple wall on either side is measured for height and sheathing. If the floors sit at different levels, the step itself becomes a weak line that the engineer has to tie across with straps or a new beam. A slab addition beside a raised floor needs a connection detail that lets each part carry its share of sideways force.

LADBS checks the structural plans for North Hills, a part of the City of Los Angeles, and inspects each stage. Bolting and cripple wall bracing on a plain raised floor can follow the city's prescriptive standard plan. Once an addition seam, a soft first story or a footing repair enters the scope, an engineer prepares calculations and stamps the sheets. Mission Hills, Panorama City, Lake Balboa, Granada Hills, Northridge and Arleta are neighbors, all inside the same city, and a house in any of them with a room added later gets its seam traced before anything is quoted.
