Custom decks and outdoor living for the West San Gabriel Valley
Pasadena, South Pasadena and San Marino are full of older homes, from Craftsman bungalows to mid-century ranches, where a deck has to suit the house as much as the yard. Out toward Arcadia, Sierra Madre and Monrovia, the lots climb toward the San Gabriel Mountains and the views get bigger.
Summers here are hotter than on the coast, so shade and heat matter: a pergola over the deck, lighter-colored boards, and a layout that catches the evening breeze.
What decks face in the West San Gabriel Valley
Heat. Inland summers are hot. Dark composite boards can get uncomfortable underfoot in full sun, so lighter colors, shade structures and good airflow under the deck all help.
Older homes. Attaching a new deck to an older house means checking the framing it hangs on and flashing the connection so water never gets behind it.
Foothill fire zones. If your home sits in a mapped Very High Fire Hazard Severity Zone, the California building code’s wildfire rules (Chapter 7A of the Building Code, Section R337 of the Residential Code) apply to the deck, including the walking surface. That usually means ignition-resistant or noncombustible decking, and a coating or stain does not count as protection. Check your address on CAL FIRE’s Fire Hazard Severity Zone map before you choose materials, and see the State Fire Marshal’s page on wildland building codes.
Deck permits in the West San Gabriel Valley
Each city in the valley runs its own building department or contracts with LA County Public Works Building & Safety, and some, like Pasadena and South Pasadena, also review projects in historic districts. Unincorporated areas such as Altadena go through the county, with online applications on EPIC-LA.
Our deck permit guide explains when a deck needs a permit across the county.

Decks in the West San Gabriel Valley: common questions
In full summer sun, darker boards do get hot. Lighter colors, a pergola or shade sail, and keeping the deck open underneath for airflow all make a real difference.
Usually, yes, with care. The connection to the house is the critical part, and homes in historic districts may need design review in addition to the building permit.
If the home is in a mapped Very High Fire Hazard Severity Zone, the state wildfire building rules apply to the deck surface. Check CAL FIRE’s Fire Hazard Severity Zone map for your address.
Yes. Planning the pergola with the deck is easiest, because its posts can be carried down to their own footings. See our pergola construction page.
