Expense Narrative [Text Block] rr_ExpenseNarrativeTextBlock

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 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 132 in the Fund's Prospectus and under “Buying and Selling Shares” on page 51 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.

Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock

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 12.74% of the average value of its portfolio.

Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock 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:

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Under normal market conditions, the Fund invests at least 80% of its total assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax. In addition, under normal market conditions, the Fund invests at least 80% of its total assets in securities that pay interest free from the personal income taxes, if any, of Michigan. 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).

Because of its historical investment policy of investing in insured municipal securities, the Fund’s portfolio may consist to a large extent of insured municipal securities. Insured municipal securities are covered by insurance policies that guarantee the timely payment of principal and interest. The 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 also may consider the cost of insurance when selecting securities for the Fund.

Risk [Heading] rr_RiskHeading Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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.

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.

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.

Michigan

The Fund invests predominantly in Michigan municipal securities. Therefore, events in Michigan 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 Michigan. 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.

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.

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.

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.

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.

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.

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.

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 information for Class R6 shares is not shown because this class did not have a full calendar year of operations as of the date of this prospectus.

Historical performance for Class A shares in the bar chart and table above prior to their inception is based on the performance of Class A1 shares and has not been adjusted to reflect differences in Rule 12b-1 fees between classes. If Class A shares’ performance was recalculated to reflect Class A shares’ Rule 12b-1 fees, the performance shown would be lower.

Historical performance for Advisor Class shares prior to inception is based on the performance of Class A1 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 A shares on September 10, 2018.
[2] There is a 0.75% contingent deferred sales charge that applies to investments of $500,000 or more (see "Investments of $500,000 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.
[3] The Fund began offering Class A shares on September 10, 2018. Other expenses for Class A are based on estimated amounts for the current fiscal year.
[4] Other expenses for Class R6 shares have been restated to reflect current fiscal year expenses. Consequently, the total annual Fund operating expenses differ from the ratio of expenses to average net assets shown in the Financial Highlights.
[5] The transfer agent has contractually agreed to cap transfer agency fees for Class R6 shares of the Fund so that transfer agency fees for that class do not exceed 0.03% for the next 12-month period. Contractual fee waiver and/or expense reimbursement agreements may not be changed or terminated during the time period set forth above.
[6] Effective October 5, 2018, Class C shares that have been held for 10 years or more will convert automatically into Class A shares later in the month of October 2018 and will be subject to Class A shares’ lower Rule 12b-1 fees. Thereafter, Class C shares of the Fund will convert automatically to Class A shares of the Fund on a monthly basis in the month of, or the month following, the 10-year anniversary of the Class C shares’ purchase date. Such conversions will be on the basis of the relative net asset values of the two classes, will not be subject to Class A shares’ sales charges and are not expected to be a taxable event for federal income tax purposes. Certain shares that are invested through retirement plans, omnibus accounts or in certain other instances may not automatically convert if the financial intermediary does not have the ability to track purchases to credit individual shareholders’ holding periods. (See “Your Account – Choosing a Shares Class – Sales Charges - Class C – Automatic Conversion of Class C Shares to Class A Shares After 10-Year Holding Period” for more information.)
[7] The Fund began offering Class R6 shares on August 1, 2017.
