New roof installation in San Pedro covers a roof on an addition, an ADU or a new building, specified in the plans and permitted by LADBS. The neighborhood is in climate zone 6, and ACS 2020-2024 puts the median year built at 1968.
Who permits it
San Pedro belongs to the City of Los Angeles, and LADBS keeps a counter in the neighborhood. Express permits are for re-roofs, so ask LADBS how a roof on new work is routed and what it needs to see (LADBS, 2026).
Planning the roof alongside the structure avoids surprises at inspection.
Reading the plans
The sheet for a roof names the slope, covering, underlayment and flashing at walls, vents and valleys. In zone 6, the figures that count for a home are the City's: SRI 20 on a steep slope and SRI 78 on a low slope (LADWP, 2022). The state's steep-slope table lists zone 4 and zones 8 through 15 and not zone 6.
About 6,401 owner-occupied single-family homes are counted in San Pedro (ACS 2020-2024).
Fire class and wildland rules
Check the address on the CAL FIRE map viewer. LAFD names portions of San Pedro among the Very High zones, and Class A is the City's rule inside them (LADBS, 2026).
On new work, vents, eaves and gutters are governed by Title 24 Part 7 (DGS/California Building Standards Commission, 2025).
