Home remodeling Concord
Where a Concord kitchen remodel turns into new construction
Concord treats a kitchen remodel as permit work whether the fittings are new or like-for-like, so the question is never whether to pull a permit but how far the scope reaches. Two thresholds decide that. Take out half the building's wall length and half the roof within one year and Information Bulletin IB-001 calls the job new construction. Add more floor area than the house already has, past 3,600 square feet all told, and fire sprinklers come with it.

How remodeling work goes in Concord
Concord documents that decide the size of the job
The 50 percent line, IB-001 and IB-031
The Chief Building Official's first bulletin draws the boundary. An alteration counts as new construction once 50 percent or more of the linear length of the building's walls, exterior plus interior, and 50 percent of the roof are removed or replaced within one year. Past that mark the building and energy plan checks are run as new construction, and the inspections follow the codes in effect at submittal. The fire-sprinkler bulletin measures the same way: alterations under the line match whatever the house already has, and alterations over it require sprinklers under the fire district's amendments.
City of Concord, Information Bulletin IB-001 (opens in a new tab)Alterations inside a mapped flood zone
The submittal requirements for residential alterations add a line that catches whole-house work. Where the site sits in any flood zone other than Zone X and the cumulative cost of the alteration reaches half the market value of the existing structure, land excluded, before construction starts, the application needs a flood elevation certificate and a foundation designed per California Residential Code R306. The city points owners to its Forerunner parcel lookup to check the zone, and ordinances bar a building permit inside a Special Flood Hazard Area until the Engineering Division has issued a separate SFHA permit under Municipal Code Chapter 15.75.

Concord's construction and demolition recycling ordinance, Municipal Code Title 8 Article III beginning at Section 8.20.333, requires at least 65 percent of a covered project's waste to be diverted from landfill and at least 75 percent of its inert debris, which includes concrete, asphalt, brick and similar masonry. Since July 1, 2013 the plan and the final report are filed in Green Halo, against a list of approved facilities, and the receipts have to show weight, material type and disposition. Self-hauling sits in Section 8.20.400; a contractor who is not self-hauling must use Mt. Diablo Resource Recovery, the only hauler permitted inside city limits.
City of Concord Building Division (opens in a new tab)A landmark's interior is inside the review
A kitchen is an interior room, and here that does not keep it out of historic review. The Certificate of Appropriateness, the application covering changes to a Designated Historical Landmark, asks for a written statement describing in detail any change to the design, building elevations, interior or grounds that would change a historically significant aspect of the landmark, or destroy or remove it. The checklist also calls for a title report prepared within the past three months in two copies, one full-size plan set at 24 by 36 inches with two reduced sets, and a rendered site plan submitted rolled rather than folded.
