A search for “R-Permit vs. A-Permit vs. B-Permit in Los Angeles” can make the three sound interchangeable. They are not. Each has a different general purpose, and the details of the proposed work determine the applicable path. This guide offers a starting framework—not a permit determination.
R-Permit, A-Permit, and B-Permit at a glance
| Permit | General purpose | Typical project relationship | Important note |
|---|---|---|---|
| R-Permit | Allows a private encroachment in the public right-of-way on a conditional, revocable basis. | Addresses the continued private use or placement of an encroachment. | It is discretionary and does not replace a construction permit. |
| A-Permit | Generally allows minor street construction in the public right-of-way. | May authorize relatively minor construction associated with an approved scope. | The City determines whether the work fits the A-Permit pathway. |
| B-Permit | Generally covers design and/or construction of major street, sewer, storm drain, or structural improvements. | May apply when work establishes new grades, elevations, depths, or structures. | Plan checking, engineering, and inspection requirements depend on the improvement. |
What an R-Permit generally addresses
A Los Angeles Revocable Permit, commonly called an R-Permit, concerns certain private encroachments in a street or other public right-of-way. The permit does not transfer ownership of public space. It allows an encroachment subject to City conditions, and the City may revoke the permission.
Examples can include certain non-standard sidewalk treatments, driveway bridges, structural projections, fences or gates, landscaping, or other private improvements. Inclusion in an example list does not mean a particular proposal qualifies. Location, dimensions, public need, accessibility, utilities, maintenance, and agency review can change the result.

What an A-Permit generally addresses
The Bureau of Engineering describes an A-Permit as a permit for minor street construction in the public right-of-way. The permit can relate to construction such as limited curb, gutter, sidewalk, driveway, or other street work when the proposed scope meets City criteria.
“Minor” is not a label the applicant should assign independently. The City evaluates the work, its engineering implications, and the required plan or inspection pathway. A project that begins with a seemingly small improvement can require another approval if field conditions or scope exceed the A-Permit framework.
What a B-Permit generally addresses
A B-Permit generally applies to the design and/or construction of major public improvements involving streets, sewers, storm drains, or structures. BOE’s permit manual identifies work that creates new grades, elevations, depths, or structures as a defining relationship.
B-Permit work can require engineered plans, plan checking, clearances, construction inspection, and other technical coordination. A structural feature associated with an R-Permit—such as certain retaining walls, driveway bridges, or substantial projections—may also need B-Permit processing. The precise requirements remain a City determination.
Why one project may need more than one permit
The simplest way to understand the relationship is to separate permission for the private encroachment from permission to construct public-right-of-way improvements. An R-Permit can address the first issue while an A-Permit, B-Permit, Excavation Permit, or another authorization addresses construction.
For example, City review might conditionally allow a private feature through an R-Permit but still require a construction permit before installation. Conversely, a construction permit does not automatically grant the ongoing right to keep a private encroachment in public space.
More than one permit may apply. The City of Los Angeles determines the final permit pathway, requirements, approvals, fees, and conditions for the actual project.
Applicants should describe the complete project rather than requesting a permit based only on its familiar name. Use the R-Permit application process guide to understand how initial information and City review shape the next steps.
Common questions
Does an R-Permit authorize construction?
Not by itself. BOE expressly notes that the R-Permit does not relieve the permittee from obtaining other required permits, including permits needed for construction.
Can an applicant choose between an A-Permit and a B-Permit?
The applicant can describe the proposed work, but the applicable City office determines the correct permit and technical review pathway.
Does every R-Permit project also require an A- or B-Permit?
No universal rule applies. The need for a construction or related permit depends on what will be built, altered, excavated, or maintained.
