What is different about dryer vent cleaning in San Diego
- San Diego's post-war and later housing is overwhelmingly slab-on-grade single-story with stucco exteriors, which routes dryer ducts horizontally through wall cavities or ceilings rather than on the short vertical runs common in basement-equipped regions.
- The City of San Diego's Development Services Department publishes its own technical bulletin on dryer exhaust (RESD-3-2), summarizing the California Mechanical Code limits on duct length, material and termination.
- The city's canyon-adjacent neighborhoods see bird nesting in exterior dryer terminations at a higher rate, and the mild climate extends that nesting season.
Horizontal Runs Are the Local Problem
Construction type determines this more than anything else. A house with a basement usually has a short duct going more or less straight out. San Diego's slab-on-grade single-story housing does not have that option.
The duct instead travels horizontally — through a wall cavity, along a ceiling void, around corners to reach an exterior wall. Lint moves through a straight run reasonably well. On a long horizontal route with elbows, it settles at every change of direction, and it accumulates from the first load.
What the City's Own Bulletin Says
The City of San Diego sets out the dryer duct rules in Technical Bulletin RESD-3-2. A standard 4-inch smooth metal duct can run 14 feet including two 90-degree bends, with 2 feet taken off for each extra bend. A flexible connector of up to 6 feet is allowed behind the dryer, but it cannot be hidden in the structure or joined to another flexible piece.
The duct has to end outside with a back-draft damper and no lint screen over the outlet. On a long horizontal route through a slab-on-grade house, that length limit is the first thing to check if loads are taking longer to dry.
Nesting at the Termination
The exterior hood with its flap is a sheltered, warm opening in a wall, and in San Diego's canyon-adjacent neighborhoods birds find it reliably. The mild climate extends the nesting season well beyond the spring window.
A nest at the termination blocks the duct completely and is easy to miss because nobody inspects the outside of their house at that level. It is worth checking the flap actually opens when the dryer runs. This is entirely separate from chimney work, despite the two often being bundled.
