City of LA · Los Angeles County
LADBS is not one counter, it is several, and the fastest route through it depends on which district office your address falls under. That is a knowledge problem, not a design problem. Plan review here runs through LADBS plan check, with City Planning sign-off where zoning discretion applies, with LAFD on access and life safety. Typical experience is roughly 10 to 18 weeks to permit, driven mostly by how many correction cycles the first submittal triggers.
Enormous range, from 1910s craftsman to 1960s stucco boxes, with lot slopes that decide half the budget. On the commercial side, change of use, occupancy load and accessibility upgrades are where LA tenant improvements gain or lose months. Those two facts explain most of what is easy and most of what is expensive here.
LADBS plan check, LAFD clearance and school fees stack quickly on anything over 1,000 sq ft of new area. We put the local fee picture into the first budget, because a number that ignores school, sewer and utility charges is not a budget, it is an advertisement.
