BSS / StreetsLA BMP Permits, Los Angeles (Explained)
A Building Materials Permit (BMP) (often referenced under BSS / StreetsLA) is commonly required when a construction project places materials, equipment, staging, or temporary obstructions within the public right-of-way, such as streets, curb lanes, sidewalks, and parkways. Requirements vary based on location, footprint, duration, access impacts, and work hours.
This page is informational. Public Ready confirms what applies to a specific project during review.
What a BMP permit is (Los Angeles)
A BMP permit is used to regulate construction-related occupancy of the public right-of-way. It may apply when you are:
Staging materials (pipe, conduit, rebar, lumber, spoils)
Placing equipment (generators, lifts, compressors, crane, boom pumps)
Using containers/dumpsters or stockpiles
Reducing sidewalk width or pedestrian access
Occupying curb lanes or affecting parking/loading
Setting up temporary work zones that affect traffic or access
Key idea: BMPs are about public space impacts, not just construction on private property.
When a BMP is typically required
A BMP is commonly triggered when any part of your operation extends into:
Sidewalks / pedestrian paths
Curb lanes / travel lanes
Parkways / shoulder areas
Public parking zones
Alley access points
Areas near intersections, bus stops, driveways, hydrants, or ramps
Even small footprints can trigger a permit when they affect ADA access, safety, or visibility.
What usually changes the requirements
BMP requirements can become more involved depending on:
Work footprint: how much space you occupy
Duration: number of days / phases
Work hours: especially time-restricted areas
Location sensitivity: major streets, downtown zones, near schools
Access impacts: driveways, loading zones, emergency access
Pedestrian impacts: ADA path of travel changes
Traffic impacts: cones, lane reductions, flagging, detours, full closures
Rule of thumb: The more your job alters movement (pedestrians/vehicles), the more documentation may be required.
When a Traffic Control Plan (TCP) may be required
A BMP does not always require a Traffic Control Plan. A TCP is typically required when your work affects:
A travel lane or requires lane control
A sidewalk path and needs pedestrian routing
Visibility or turning movements near intersections/driveways
Loading/unloading operations that impact traffic flow
Any condition requiring cones, signs, or controlled access
When required, the TCP documents how the work zone will be set up safely and how traffic/pedestrians will be maintained.
Important: TCP requirements depend on the governing agency’s conditions and the project’s real-world impacts.
Temporary no-parking coordination (when applicable)
Some BMP-related work may require temporary parking restrictions to support staging, safe loading/unloading, pedestrian routing, or equipment placement.
In Los Angeles, permit conditions may require a Temporary Tow Away / No Parking Invoice, Work Order, and Log (proof the request was ordered) before a permit is issued. These requests typically require advance lead time, often up to 10 business days (excluding weekends and City holidays) and fees are generally required before posting occurs. Tow-away signs are commonly posted ahead of the restriction start, and enforcement is typically tied to a log number and proper notice timing. Requirements and timelines vary and are subject to change.
What to gather before you request a BMP
Having these ready speeds up confirmation and review:
Exact job address (or nearest cross streets)
Work dates and daily work hours
Clear description of what will occupy the ROW
Photos of the area (wide + close)
Sketch or site plan showing approximate footprint
Any agency notes, emails, or requirements you received
If equipment is involved: basic dimensions / spec sheet
Common BMP situations (examples)
Dumpster/container in a parking lane
Material stockpile on sidewalk/parkway
Staging equipment on curb lane during work window
Pedestrian path reduced, needs a temporary routed walkway
Delivery operations requiring controlled curb access
(Keep these as examples only, don’t imply “approved.”) If equipment is involved: basic dimensions / spec sheet
Important Note (Los Angeles BMP Permits)
This page is informational and reflects common patterns. Permit requirements, review steps, fees, and timelines are set by the governing agency and can vary by location, work type, and impacts. If conditions trigger work zone documentation, a Traffic Control Plan (TCP) and/or temporary no-parking coordination may be required.
