San Leandro, California Building Permit Guide

San Leandro is an East Bay city of about 85,000 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.

What requires a building permit in San Leandro?

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); 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 California Wildland-Urban Interface Code (Title 24, Part 7, in force since 1 January 2026) and Cal Fire defensible-space requirements (Public Resources Code 4291) 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.

California builds on one statewide code, Title 24, whose 2025 edition took effect on 1 January 2026; the editions in effect when the application is submitted apply, and cities and counties may adopt local amendments only with findings filed with the state (new residential amendments are largely frozen until June 2031).

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.

The Building and Safety Division runs plan review, permit issuance and inspection from the Permit Center on the first floor of City Hall, with multi-lingual staff and translation services available. Applications are filed through the city’s online permit portal, and counter appointments are prioritised over walk-ins, with walk-ins asked to arrive well before closing. 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.

In 2025, building permits issued in San Leandro authorized 62 new privately owned housing units, all of them single-family homes, according to the U.S. Census Bureau Building Permits Survey.

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.

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.

Contractors are licensed statewide by the Contractors State License Board (Classes A, B, B-2 and C) for work of $1,000 or more or any permitted work; a city may also require a business licence or tax registration. Contractor licensing in California

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.

California layers two uniform state surcharges — the Building Standards Administration fee and the Strong Motion Instrumentation seismic fee — on top of the local charges (Health and Safety Code 18931.6; Public Resources Code 2705). 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

Each trade follows its part of Title 24 and is done by a contractor with the matching CSLB licence (C-10 electrical, C-36 plumbing, C-20 HVAC), a Class B contractor where allowed, or an owner-builder. Trade licences in California

How to apply for a San Leandro building permit

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.

A building permit carries a validity period and can expire if work does not start or stalls between inspections; confirm the expiry with San Leandro on phased or delayed work. Permit validity in California

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 made against the code editions in effect when the permit application was submitted (Health and Safety Code 18938.5), 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.

These are the primary sources behind this guide. Codes, fee schedules and procedures change — confirm the position for your filing date.
