San Leandro is an East Bay city of about eighty-seven thousand residents on the bay shore south of Oakland, with a large industrial and manufacturing base and a dense post-war housing stock. Its Building and Safety Division, within Community Development at the Permit Center in City Hall, is the sole building authority inside the city.
This guide covers the Building and Safety Division and Permit Center, the permit process, the codes in force, and the retrofit and floodplain programmes that shape San Leandro projects.
This guide covers work inside the City of San Leandro limits. Unincorporated Alameda County and neighbouring cities are separate authorities.
San Leandro puts its building codes in its own municipal code, and charges permits in stages. The city’s building codes sit in Title 7, Chapter 7-5 of the municipal code, with the current edition in force from January 2026. Permit fees arrive in at least two payments: a filing and issuance fee invoiced when the permit record is created, then the balance based on project valuation.
What requires a building permit in San Leandro?
California builds on a single statewide code — the California Building Standards Code, known as Title 24 — adopted on a three-year cycle by the California Building Standards Commission. The 2025 edition took effect on January 1, 2026 and governs statewide. Cities and counties enforce Title 24 and may adopt local amendments, but an amendment must be filed with the state and may only be equal to or more restrictive than the state code, justified by local climatic, geologic or topographic conditions. So the first question in San Leandro is which authority has jurisdiction — the city on incorporated parcels, the county in unincorporated territory — and what local amendments sit on top of Title 24.
Permit required
- New commercial, multi-family and residential construction, additions and change of occupancy
- Structural alterations, load-bearing changes, foundations, decks and retaining walls
- Electrical work — services, panels, circuits, solar and EV charging — under the California Electrical Code
- Plumbing under the California Plumbing Code, tied to a licensed contractor
- Mechanical and HVAC change-outs, and work affecting the Title 24 energy envelope
- Re-roofing above the exempt scope, pools, signs, and demolition
Often exempt
- Minor repairs and maintenance replacing materials in kind
- Small accessory structures below the local threshold, where zoning allows
- Painting, flooring, cabinetry and other finish work
- Like-for-like fixture or appliance swaps with no alteration to wiring or piping
Local amendments and thresholds differ from one jurisdiction to the next, so an exempt list from a neighbouring city is not reliable — a project waved through in one place needs a full permit set in the next. An exemption from a building permit is never an exemption from zoning, the statewide energy or green-building codes, or an electrical or plumbing permit. Confirm scope with Building and Safety before work starts.
The statewide layers that apply everywhere
Several parts of Title 24 apply on top of the base building code and routinely catch projects owners assume are exempt: the California Energy Code (Part 6), among the strictest in the nation; CALGreen (Part 11), California’s mandatory statewide green-building code; and the accessibility provisions in Chapters 11A and 11B. Seismic design is built into the code statewide, and in fire-prone areas the wildland-urban-interface rules of Chapter 7A and Cal Fire defensible-space requirements add a further layer. In the City of San Leandro, the Building and Safety Division administers Title 24 through the city’s own municipal code chapter, and the department also oversees the federal floodplain programme and the earthquake retrofit programme.
Who handles permitting in San Leandro?
The Building and Safety Division processes building permit applications, answers questions on current building codes and plan submittal requirements, and oversees the floodplain and earthquake retrofit programmes.

Permits can only be issued to a California-licensed contractor or to a property owner.
Confirm the parcel is inside the city first; unincorporated Alameda County and the neighbouring East Bay cities file with different authorities under their own amendments.
Permit types
Residential permits
Residential work inside the city is permitted and inspected by the division under Title 24 and the city’s municipal code chapter. Additions, ADUs, reroofs, pools, solar and EV chargers need permits, and contractors registered with the state streamlined solar review system can obtain an instant solar permit for qualifying residential projects. Some construction work does not go through plan review at all.
How California contractor credentials work
California licenses contractors statewide through the Contractors State License Board, not locally. The CSLB issues three license types — Class A for general engineering, Class B for general building, and the Class C specialty classifications for individual trades — and a contractor must hold the classification that matches the work. A license is required for any project valued at one thousand dollars or more in combined labour and materials, and, in practice, for any work that requires a permit regardless of value.
In California the license lives with the state, not the city. The same CSLB license is recognised in every jurisdiction, so there is no separate local contractor registration to secure before pulling a permit. What the permitting authority does check is that the license number is active and carries the right classification for the scope, along with workers’ compensation coverage. Confirm the classification matches before filing.
Commercial permits
Commercial and industrial work goes through division plan review against the California Building Code, the Energy Code and CALGreen, with city amendments. Plans, specifications, energy calculations, soils reports and other data are required on new construction, and applicants should allow between five and twenty business days for initial plan review depending on complexity.
Licenses, trade classifications and design professionals
Practically, three credential layers appear on California projects: a CSLB license in the correct classification for the contractor pulling the permit; the specialty C-classifications for the electrical, plumbing and mechanical trades; and, on commercial and larger residential work, drawings stamped by a California-licensed architect or engineer. Confirm what Building and Safety requires for the specific building before filing.
San Leandro permit costs and fees
Budget the city building permit and plan-review fees in at least two payments, separate trade permits, the state Building Standards and seismic surcharges, and any development impact fees. Most building permits are based on project valuation; confirm the schedule in force on your filing date.
| Fee component | How it works |
|---|---|
| Building permit | Based on project valuation or square footage; set by the local schedule |
| Plan check | A percentage of the permit fee or a flat charge, at submittal |
| Trade permits | Separate electrical, plumbing and mechanical fees |
| State surcharges | Building Standards and seismic (SMIP) fees collected with the permit |
| Impact and school fees | Development impact and school-district fees in growth areas |
| Re-inspections and revisions | Additional fees for failed inspections, revisions and expired permits |
California layers two uniform state surcharges — the Building Standards Administration fee and the Strong Motion Instrumentation seismic fee — on top of the local charges, so they appear on permits everywhere. The building and plan-check fees themselves are local and change, and California law limits them to the reasonable cost of providing the service, so a figure from a neighbouring city is not reliable — ask Building and Safety for the schedule in force on your filing date.

Trade permits and who may pull them
Trade permits are separate from the building permit and, on projects that require one, generally cannot be issued until the building permit is in place. Each trade follows its own part of Title 24 — the California Electrical, Plumbing and Mechanical Codes — and is tied to a contractor holding the matching CSLB specialty classification, the same license statewide.
California runs the trades on one statewide license. Electrical work is tied to a C-10 contractor, plumbing to a C-36, and heating and air to a C-20, each licensed by the CSLB rather than the city, so the credential travels with the contractor from one jurisdiction to the next. What changes locally is the permit itself and any local amendments — confirm both with the authority that issues it.
- Electrical work follows the California Electrical Code and a C-10 electrical contractor.
- Plumbing work follows the California Plumbing Code and a C-36 plumbing contractor.
- Mechanical work follows the California Mechanical and Energy codes and a C-20 HVAC contractor.
Permit required
- Service installations, panel upgrades, new circuits, solar PV and EV chargers
- New plumbing, repipes, water heater change-outs, fixtures, backflow and gas piping
- HVAC installation and change-out, ductwork, venting and commercial kitchen exhaust
- Sprinkler, standpipe and fire alarm work on commercial and multi-family structures
Typically exempt
- Replacing a fixture, switch, receptacle or light with no alteration to wiring or piping
- Clearing a stoppage without replacing or rearranging concealed piping
- Filter, thermostat and routine component service
- Like-for-like appliance repair that does not alter the connection

Review, corrections and what actually causes delay
In California, the first cause of delay is uncertainty over jurisdiction — filing with the county when a city should have it, or missing a local amendment on top of Title 24. After that come Title 24 energy and CALGreen documentation, a CSLB classification that does not match the scope, and, in fire or coastal areas, defensible-space or coastal-zone requirements that were not addressed up front. Build the plan-check time into the schedule and confirm the checklist with Building and Safety before filing.
Approvals do not stay live indefinitely. A California building permit carries a validity period and can expire if work does not start or stalls between inspections. On phased or financed work, keep the permit active with periodic progress inspections and confirm the expiry window before it passes.
Inspections in San Leandro
Where a permit is required, standard checkpoints include footing and foundation, framing, rough-in electrical, plumbing and mechanical, insulation and Title 24 energy, CALGreen measures, fire systems on commercial work, and final, with a certificate of occupancy before use. Inspections are scheduled through the online permit portal against the issued permit record, which requires a portal account.
California inspections are keyed to the code editions in force when the permit issued, so the approved plans and any energy and green-building documentation need to be on site for the inspector to check against. Confirm the notice Building and Safety needs and schedule around its inspection windows.
Do not cover work before the required inspection has been approved. Keep the issued permit, the approved plans, product listings, Title 24 energy documentation and your correction responses available on site.
San Leandro permit search and official resources
Permit records in California sit with the local authority that issued them. Where the City of San Leandro Building and Safety Division is the authority for the City of San Leandro limits, it holds the building permit, the inspection history and the certificate of occupancy. If you are buying, refinancing or renovating, confirm that past work was permitted rather than assuming it was — and confirm the code edition that was in force.
Confirm the authority having jurisdiction and the local amendments first. California enforces one statewide code, Title 24, but each city and county adds its own amendments and fee schedule, so the requirements that apply vary by parcel. Confirm current requirements, fees and review turnaround for your filing date.
