Professional Room Addition Demolition in San Dimas, CA
Room addition and sunroom demolition is one of the more legally complex demo scopes in residential construction because many additions — particularly those built in the 1970s through 1990s — were added without permits, without proper tie-ins to the original structure, or with materials and methods that no longer meet code. Removing an unpermitted addition is often required by a new owner's lender or insurer, or as a condition of a re-permit project where the homeowner wants to legalize or upgrade the space. Your written bid states which permits the job needs and who pulls them; permit fees are the owner's unless the bid says otherwise. C&S documents the teardown and clearly defines the resulting condition of the original structure.
The structural connection between the addition and the original house is the critical zone. An addition shares a wall, a roof plane, or a floor system with the main structure — and tearing it away without understanding those connections can leave openings in the building envelope, damage existing framing, or remove load contributions that the main structure was relying on. Structural review by the owner's engineer when the connection is load-bearing; shoring and bracing are not included.
Cost factors include addition size, construction type (light wood frame versus masonry or heavy structural), roofing material, the complexity of the structural connection, any regulated materials discovered, and the required condition of the main structure after removal (patched and weatherproofed versus rough open framing). C&S gives a written lump-sum bid after seeing plans or photos. Most addition demos complete in one to two days. The licensed, documented approach C&S brings protects the property owner's title and provides a clean record for the building department.
