Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of the period. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example {- Franklin California Intermediate-Term Tax-Free Income Fund} - Franklin California Tax-Free Trust-15 - Franklin California Intermediate-Term Tax-Free Income Fund - USD ($)	Class A	Class C	Class R6	Advisor Class
1 year	$ 288	$ 220	$ 51	$ 54
3 years	422	375	160	170
5 years	568	649	280	296
10 years	$ 994	$ 1,432	$ 628	$ 665

If you do not sell your shares:

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 3.91% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of its total assets in securities that pay interest free from federal income taxes, including the federal alternative minimum tax, and from California personal income taxes. Under normal market conditions, the Fund invests at least 65% of its total assets in California municipal securities. The Fund also may invest up to 35% of its total assets in municipal securities issued by U.S. territories, such as Puerto Rico. Although the Fund tries to invest all of its assets in tax-free securities, it is possible, although not anticipated, that up to 20% of its total assets may be in securities that pay taxable interest, including interest that may be subject to the federal alternative minimum tax. Some of the Fund's portfolio securities are supported by credit enhancements, which may be provided by either U.S. or foreign entities.

The Fund maintains a dollar-weighted average portfolio maturity of three to 10 years and only buys securities rated, at the time of purchase, in one of the top four ratings categories by one or more U.S. nationally recognized rating services or comparable unrated or short-term rated securities.

The Fund may invest in insured municipal securities, which are covered by insurance policies that guarantee the timely payment of principal and interest. The insurance premium costs, however, are typically reflected in a lower yield and/or higher price for the insured bond. It is important to note that insurance does not guarantee the market value of an insured security, or the Fund’s share price or distributions, and shares of the Fund are not insured.

Although the investment manager will search for investments across a large number of municipal securities that finance different types of projects, from time to time, based on economic conditions, the Fund may have significant positions in municipal securities that finance similar types of projects.

The investment manager selects securities that it believes will provide the best balance between risk and return within the Fund’s range of allowable investments and typically uses a buy and hold strategy. This means it generally holds securities in the Fund’s portfolio for income purposes, rather than trading securities for capital gains, although the investment manager may sell a security at any time if it believes it could help the Fund meet its goal. The investment manager also may consider the cost of insurance when selecting securities for the Fund.

Principal Risks

You could lose money by investing in the Fund. Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government.

Interest Rate

When interest rates rise, debt security prices generally fall. The opposite is also generally true: debt security prices rise when interest rates fall. Interest rate changes are influenced by a number of factors, including government policy, monetary policy, inflation expectations, perceptions of risk, and supply and demand of bonds. In general, securities with longer maturities or durations are more sensitive to interest rate changes.

California and U.S. Territories

Because the Fund invests predominantly in California municipal securities, events in California are likely to affect the Fund's investments and its performance. These events may include economic or political policy changes, tax base erosion, state constitutional limits on tax increases, budget deficits and other financial difficulties, and changes in the credit ratings assigned to municipal issuers of California. As with California municipal securities, such events in any of the U.S. territories in which the Fund invests, which can include Puerto Rico, Guam and the U.S. Virgin Islands, may affect the Fund's investments and its performance.

Focus

The Fund may invest more than 25% of its assets in municipal securities that finance similar types of projects, such as utilities, hospitals, higher education and transportation. A change that affects one project, such as proposed legislation on the financing of the project, a shortage of the materials needed for the project, or a declining need for the project, would likely affect all similar projects, thereby increasing market risk.

Credit

An issuer of debt securities may fail to make interest payments or repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security's credit rating may affect a security's value.

A change in the credit rating of a municipal bond insurer that insures securities in the Fund’s portfolio may affect the value of the securities it insures, the Fund’s share price and Fund performance. The Fund might also be adversely impacted by the inability of an insurer to meet its insurance obligations.

Tax-Exempt Securities

While the Fund endeavors to purchase only bona fide tax-exempt securities (i.e., a security issued as paying tax-exempt interest income), there are risks that: (a) a tax-exempt security may be reclassified by the Internal Revenue Service, or a state tax authority, as paying taxable interest income instead and/or (b) future legislative, administrative or court actions could adversely impact the qualification of income from a tax-exempt security as tax-free. Such reclassifications or actions could cause interest from a security to become taxable, possibly retroactively, subjecting you to increased tax liability. In addition, such reclassifications or actions could cause the Fund to have to sell securities at inopportune times or prices and may cause the value of the security, and therefore the value of the Fund’s shares, to decline.

Income

Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.

Bond Insurers

Market conditions or changes to ratings criteria could adversely impact the ratings of municipal bond insurance companies. Downgrades and withdrawal of ratings from municipal bond insurers have substantially limited the availability of insurance sought by municipal bond issuers thereby reducing the supply of insured municipal securities.

Because of the consolidation among municipal bond insurers the Fund is subject to additional risks including the risk that credit risk may be concentrated among fewer insurers and the risk that events involving one or more municipal bond insurers could have a significant adverse effect on the value of the securities insured by an insurer and on the municipal markets as a whole.

Prepayment

Prepayment risk occurs when a debt security can be repaid in whole or in part prior to the security's maturity and the Fund must reinvest the proceeds it receives, during periods of declining interest rates, in securities that pay a lower rate of interest. Also, if a security has been purchased at a premium, the value of the premium would be lost in the event of prepayment. Prepayments generally increase when interest rates fall.

Market

The market values of securities or other investments owned by the Fund will go up or down, sometimes rapidly or unpredictably. The market value of a security or other investment may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all investments. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

Liquidity

From time to time, the trading market for a particular security or type of security or other investments in which the Fund invests may become less liquid or even illiquid. Reduced liquidity will have an adverse impact on the Fund’s ability to sell such securities or other investments when necessary to meet the Fund’s liquidity needs or in response to a specific economic event and will also generally lower the value of a security or other investments. Market prices for such securities or other investments may be volatile.

Management

The Fund is subject to management risk because it is an actively managed investment portfolio. The Fund's investment manager applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results.

Performance

The following bar chart and table provide some indication of the risks of investing in the Fund. The bar chart shows changes in the Fund's performance from year to year for Class A shares.
