Chimney Rebuild for Oakland Homes

Chimney rebuild in brief

A chimney rebuild replaces masonry that repairs can no longer save. Depending on how far the damage goes, the chimney is taken down to the roofline or lower, to masonry that is still sound. It is then relaid and finished with a new crown, flashing and cap. A rebuild is the usual answer for a leaning chimney, brick that has shifted or broken apart, or a stack that is no longer stable. The full process, from teardown to final cap, is on our chimney rebuild service page.

Oakland guidance that can shape a chimney rebuild

Two pieces of City of Oakland guidance can change how a rebuild is planned. Neither applies to every home, so the first step is finding out whether either one covers yours.

Design review, preservation zones and the DRX exemption

City of Oakland permit guidance lists projects on a site with a City or State landmark, a National Register listing, or within an S-7 or S-20 preservation zone among additions/alterations subject to design review. City of Oakland guidance on Design Review Exemption (DRX) lists exterior changes that visually match the existing or historic design among alterations that can qualify for the exemption. (Source: City of Oakland, Additions, Alterations & Conversions to Habitable Space.)

For a chimney rebuild, the guidance matters in two ways:

• Who it applies to: homes on a landmark site, a National Register-listed property, or a lot inside an S-7 or S-20 preservation zone. If you aren't sure whether your property falls into one of these, confirm it with the City before the project is scheduled.
• What it changes: a rebuilt chimney is an exterior change you can see from outside. Planning it to visually match the existing or historic design, including brick, mortar color, shape, height and top detailing, is the kind of change the DRX guidance describes. The City decides whether a specific project qualifies for the exemption.

Soft-story retrofits and unreinforced masonry chimneys

Oakland Planning & Building Department Technical Bulletin 15.27-1, for the mandatory soft-story retrofit ordinance (OMC Chapter 15.27), requires the seismic evaluation scope to include unreinforced masonry (URM) chimneys and their anchorage. (Source: City of Oakland Planning & Building Department, Technical Bulletin 15.27-1, OMC Chapter 15.27.)

If your building falls under the soft-story ordinance and has an unreinforced masonry chimney, the seismic evaluation has to look at that chimney and how it is anchored. Building owners and property managers in this situation should have the evaluation findings ready when they request an estimate. That way, the rebuild scope can be planned around what the evaluation found, rather than separately from it.

When a rebuild fits, and when a smaller job will do

A rebuild makes sense when the masonry itself has failed. That means the chimney leans, bricks are loose through the full thickness, or cracking runs deep enough that patching would only hide the problem. Leaning chimney repair is nearly always a rebuild, because the stack has to come down to stable masonry and go back up straight.

Plenty of damaged chimneys don't need that much work. Worn mortar joints can often be handled with tuckpointing, and a cracked top with crown repair. Spalled or broken brick in a few areas usually calls for masonry repair. Our guide to chimney repair vs rebuild walks through how to tell them apart. If you aren't sure which job you need, a chimney inspection for homes in Oakland shows the actual condition of the masonry and flue before you commit to a rebuild.
