What permits are needed for new construction in Los Angeles?
New construction in Los Angeles requires building, electrical, plumbing, and mechanical permits through Los Angeles Department of Building & Safety (LADBS), plus any entitlements (zoning / planning review) triggered by the project. LADBS plan check runs structural, energy, residential, and grading in parallel. Expect comment cycles on Title 24 compliance, fire-sprinkler design, and grading quantities on sloped sites.
What changes the answer in Los Angeles.
Most new SFRs in R1 are ministerial; small-lot subdivisions, density-bonus projects, and any work in HPOZ / Specific Plan / Coastal areas require discretionary review through City Planning. LADBS uses district inspectors with same-day or next-day scheduling via the permit portal. Foundation, framing, insulation, drywall, and final inspections are the standard hold points.
- City of LA uses base zones (R1, R2, RD, etc.) plus overlays (HPOZ, Specific Plans, Coastal Zone, Hillside, Very-High Fire). ZIMAS is the parcel-level source of truth; always confirm overlays before scoping.
- Buildable envelope is driven by RFA / FAR, side and rear setbacks, height districts, and BMO (Baseline Mansionization Ordinance) on R1 lots. Hillside lots add slope-band area calculations.
- LADWP service upgrades (200A → 400A) are common on full rebuilds; lead times for new service drops can extend project schedules independently of plan check.
- City sewer is universal in the basin; new SFRs pay a Sewer Facilities Charge based on fixture count. Some hillside parcels still rely on private laterals that require LASAN review.
