Post-Fire Erosion Control & Debris Flow Permits for LA Rebuilds
Separate County and City grading, temporary erosion controls, state stormwater coverage and permanent LID relief before rebuilding a burned hillside lot.

Straight-talk guidance on getting permits approved in Los Angeles and across California. We write about what actually happens at the counter — how to permit an ADU, what a tenant improvement really involves, how to avoid the corrections that stall projects, and how to rebuild after disaster in areas like Pacific Palisades and Altadena. If you're a homeowner, architect, or contractor trying to understand the permit process, start here.

A few guides worth starting with: our breakdown of the Adaptive Reuse Ordinance for converting older commercial buildings, what the SB 721 / SB 326 balcony inspection law means for multifamily owners, and how a basement conversion ADU permit actually gets approved. On the smaller-scope side, we cover reroofing permits, patio covers, pergolas, and gazebos, driveway and curb cut encroachment permits, and short-term rental and home-sharing permits.

A handful of narrower questions come up often enough to deserve their own guide. If a tree on your lot is protected under LA's ordinance, our protected tree removal permit guide covers the arborist report and replacement requirements. For accessibility upgrades, we explain when an elevator or wheelchair lift needs a full building permit, and for fuel storage, how an above-ground propane tank gets sited and approved. We also cover the line between a routine repair and a permitted window, door, or skylight replacement, what qualifies as a nonconforming use or structure under LA's zoning code, and — for anyone weighing a smaller backyard project — what permit a patio cover, pergola, or gazebo actually requires. On the commercial side, we get similar questions about grocery store and supermarket permits and, for families displaced by the 2025 fires, about temporary housing and RV permits. We've also published honest comparisons against other permit-tech platforms, including our PermitFlow vs. Pulley breakdown and our Ocean Permits vs. GreenLite comparison. On the compliance side, we cover asbestos survey and SCAQMD Rule 1403 notification requirements before demolition, and the commercial kitchen hood and grease interceptor permit that comes with most restaurant build-outs.
