Fund Summary

Franklin California Tax-Free Income Fund-13 | Franklin California Tax-Free Income Fund

Investment Goal

To provide investors with as high a level of income exempt from federal income taxes, including alternative minimum tax, and exempt from California personal income taxes for California residents as is consistent with prudent investment management and the preservation of shareholders’ capital.

Fees and Expenses of the Fund

These tables describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts in Class A and Class M if you and your family invest, or agree to invest in the future, at least $100,000 in Franklin Templeton funds. More information about these and other discounts is available from your financial professional and under “Your Account” on page 31 in the Fund's Prospectus and under “Buying and Selling Shares” on page 42 of the Fund’s Statement of Additional Information. In addition, more information about sales charge discounts and waivers for purchases of shares through specific financial intermediaries is set forth in Appendix A – "Intermediary Sales Charge Discounts and Waivers" to the Fund’s prospectus.

Please note that the tables and examples below do not reflect any transaction fees that may be charged by financial intermediaries, or commissions that a shareholder may be required to pay directly to its financial intermediary when buying or selling Class R6 or Advisor Class shares.

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 Tax-Free Income Fund} - Franklin California Tax-Free Income Fund-13 - Franklin California Tax-Free Income Fund - USD ($)	Class A	Class M	Class C	Class R6	Advisor Class
1 year	$ 482	$ 497	$ 216	$ 48	$ 50
3 years	603	651	362	155	157
5 years	735	819	628	272	274
10 years	$ 1,120	$ 1,304	$ 1,386	$ 614	$ 616

If you do not sell your shares:

Expense Example, No Redemption {- Franklin California Tax-Free Income Fund}	Franklin California Tax-Free Income Fund-13 Franklin California Tax-Free Income Fund Class C USD ($)
1 Year	$ 116
3 Years	362
5 Years	628
10 Years	$ 1,386

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 13.05% 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 investment grade municipal securities whose interest is free from federal income taxes, including the federal alternative minimum tax, and from California personal income taxes. Although the Fund tries to invest all of its assets in tax-free securities, it is possible that up to 20% of the Fund's total assets may be in securities that pay interest that may be subject to the federal alternative minimum tax and, although not anticipated, in securities that pay interest subject to other federal or state income taxes.

The Fund only buys municipal 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 unrated or short-term rated securities of comparable credit quality).

The Fund may invest in insured municipal securities to the extent available. Insured municipal securities 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.

The Fund also may invest up to 35% of its total assets in municipal securities issued by U.S. territories.

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 may also 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 of and demand for bonds. In general, securities with longer maturities or durations are more sensitive to interest rate changes.

California and U.S. Territories

The Fund invests predominantly in California municipal securities. Therefore, events in California are likely to affect the Fund’s investment and its performance. These events may include economic or political policy changes, tax base erosion, unfunded pension and healthcare liabilities, constitutional limits on tax increases, budget deficits and other financial difficulties, and changes in the credit ratings assigned to municipal issuers of California. The same is true of events in other states or U.S. territories, to the extent that the Fund has exposure to any other state or territory at any given time.

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.

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.

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.

Tax-Exempt Securities

Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities.

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.

Income

The Fund's distributions to shareholders may decline when prevailing interest rates fall, when the Fund experiences defaults on debt securities it holds, or when the Fund realizes a loss upon the sale of a debt security.

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, which may arise or increase in response to a specific economic event or because the investment manager wishes to purchase particular investments or believes that a higher level of liquidity would be advantageous. Reduced liquidity will also generally lower the value of such securities or other investments. Market prices for such securities or other investments may be relatively volatile.

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.

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. The table shows how the Fund's average annual returns for 1 year, 5 years, 10 years or since inception, as applicable, compared with those of a broad measure of market performance. The Fund's past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. You can obtain updated performance information at franklintempleton.com or by calling (800) DIAL BEN/342-5236.

Sales charges are not reflected in the bar chart, and if those charges were included, returns would be less than those shown.

Class A Annual Total Returns

Best Quarter:	Q3'09	11.00%
Worst Quarter:	Q4'10	-5.58%
As of June 30, 2018, the Fund's year-to-date return was -0.53%.

Bloomberg Barclays Municipal Bond Index (index reflects no deduction for fees, expenses or taxes)	5.45%	3.02%	4.46%

Performance information for Class M shares and Class R6 shares is not shown because each of these classes did not have a full calendar year of operations as of the date of this prospectus.

Historical performance for Advisor Class shares prior to inception is based on the performance of Class A shares. Advisor Class performance has been adjusted to reflect differences in sales charges between classes.

The after-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. After-tax returns are shown only for Class A and after-tax returns for other classes will vary.

[1] The Fund began offering Class M shares on January 25, 2018.

[2] There is a 0.75% contingent deferred sales charge that applies to investments of $1 million or more (see "Investments of $1 Million or More" under "Choosing a Share Class") and purchases by certain retirement plans without an initial sales charge on shares sold within 18 months of purchase.

[1] Other expenses have been restated to exclude non-recurring prior period expenses and, for Class R6, to reflect current fiscal year fees and expenses. If the prior period's non-recurring expenses were included in the table above, the amounts stated would have been greater. Consequently, the total annual Fund operating expenses differ from the ratio of expenses to average net assets shown in the Financial Highlights.

[2] The Fund began offering Class M shares on January 25, 2018. Other expenses for Class M are based on estimated amounts for the current fiscal year.

Performance Table Closing [Text Block]

rr_PerformanceTableClosingTextBlock

Performance information for Class M shares and Class R6 shares is not shown because each of these classes did not have a full calendar year of operations as of the date of this prospectus.

Historical performance for Advisor Class shares prior to inception is based on the performance of Class A shares. Advisor Class performance has been adjusted to reflect differences in sales charges between classes.

The after-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. After-tax returns are shown only for Class A and after-tax returns for other classes will vary.

[1] There is a 0.75% contingent deferred sales charge that applies to investments of $1 million or more (see "Investments of $1 Million or More" under "Choosing a Share Class") and purchases by certain retirement plans without an initial sales charge on shares sold within 18 months of purchase.

[2] Other expenses have been restated to exclude non-recurring prior period expenses and, for Class R6, to reflect current fiscal year fees and expenses. If the prior period's non-recurring expenses were included in the table above, the amounts stated would have been greater. Consequently, the total annual Fund operating expenses differ from the ratio of expenses to average net assets shown in the Financial Highlights.

[3] The Fund began offering Class M shares on January 25, 2018. Other expenses for Class M are based on estimated amounts for the current fiscal year.

[4] The Fund began offering Class M shares on January 25, 2018.
