Chimney Rebuild for Piedmont Homes

Chimney rebuild in brief

A masonry chimney rebuild starts with taking the chimney down to solid, sound masonry. That might be just the section above the roofline, or it might go further. The chimney is then relaid with new mortar, and a new crown and properly tied-in flashing usually finish the work. It fits when the brick or stone has failed: the stack leans, bricks are loose, mortar has washed out deeply, or cracks run through the structure. For the full scope and sequence, read about how chimney rebuild works.

City of Piedmont rules that shape a chimney rebuild

Several City of Piedmont rules affect the paperwork and the finished chimney, each listed with the source it comes from. The City is the final word on which approvals your project needs, so confirm with it before work is scheduled.

When a building permit is required

Piedmont amended California Residential Code R105.1 in City Code 8.02.020. Under that amendment, a building permit is required for any alteration or property improvement that has received or requires City of Piedmont design review approval. If your rebuild goes through design review, plan on a building permit as well. Source: City of Piedmont, City Code Chapter 8, Section 8.02.020 (R105.1 Permits Required).

Chimney height and the city's height limit

Under Piedmont City Code 17.90.020, building height is not measured to the highest point of a chimney. A chimney therefore does not count toward the City's building height limit. Rebuilding a chimney to the height it needs to draft and clear the roof does not use up the home's allowed building height. Source: City of Piedmont, City Code Chapter 17, Planning and Land Use (Section 17.90.020 Measurements).

A 2026 code change for permitted chimney work

Piedmont amended California Residential Code R1003.9.2 in City Code 8.02.020, effective January 1, 2026. The amendment requires a chimney spark arrester whenever a building permit above a set valuation is issued, and the arrester must be installed before the final inspection is scheduled. A larger permitted rebuild can trigger this requirement. Include the arrester in the plan from the start so it doesn't hold up the final inspection. We install spark arresters, caps and animal screens; for the top-of-chimney options, look at chimney cap installation in Piedmont.

If taking the chimney out is on the table

Some owners weigh rebuilding against removing an unused chimney altogether. The City of Piedmont lists complete removal of exterior architectural elements, including chimneys, as not requiring a Planning permit. That applies only if the area is patched and painted to match the adjacent wall, eave or roof. Source: City of Piedmont, Projects that don't require a Planning permit.

Rebuild, repair or something smaller?

Not every damaged chimney needs to come down. Mortar loss near the surface can often be handled with tuckpointing. A cracked crown can be repaired on its own. Leaks at the roofline are often a flashing problem rather than a masonry failure. A rebuild makes sense when the structure itself is no longer sound. Examples include a leaning chimney, bricks that move by hand, or deep cracking that runs through the stack. For help with that decision, our guide to chimney repair vs rebuild walks through the signs on each side. An inspection before the estimate shows which way your chimney falls.

Booking a chimney rebuild in Piedmont

Same-day visits are available where the schedule allows, depending on that day's bookings. The estimate covers how far down the chimney needs to come and what the rebuild involves. It also flags any parts of the job that the City rules above may affect. For more detail on the work itself, read about our chimney rebuild service.
