Maryland landlord rules: late fees, deposits and rent increases
Maryland caps late fees as a share of the unpaid rent and limits the security deposit to one month's rent. It also sets a notice period for rent increases. Here is what the Real Property Article says, with the section for each rule.
The short version
- Late fee limit: 5% of the unpaid rent for the rental period.
- The statute sets no grace period for late fees.
- Deposit limit: one month's rent per dwelling unit, regardless of the number of tenants.
- Return the deposit, with simple interest, within 45 days after the tenancy ends. Itemized deductions go out by mail in the same 45 days.
- Rent increases need written notice: 60 days for a tenancy with a term of more than 1 week up to 1 month, and 90 days for a longer term.
Late fees in Maryland
- Limit
- 5% of the unpaid rent for the rental period. Where rent is due weekly, the limit is $3 per week or $12 per month. Md. Code, Real Prop. § 8-208(d)(3)
- Grace period
- None in the statute. Md. Code, Real Prop. § 8-208
- Other conditions
- A lease term that goes over the cap is unenforceable. The tenant can recover actual damages and attorney's fees. Md. Code, Real Prop. § 8-208(g)
Security deposits in Maryland
- Maximum deposit
- One month's rent per dwelling unit, regardless of the number of tenants. Up to two months' rent if the tenant qualifies for utility assistance from the state Department of Human Services, pays utilities directly to the landlord, and both agree in writing. Md. Code, Real Prop. § 8-203(b)(1)-(2)
- Return deadline
- 45 days after the end of the tenancy. Md. Code, Real Prop. § 8-203(e)(1)
- Itemized deductions
- Required, in writing, by mail within the same 45 days. Send a written list of the damages claimed with an itemized statement of the cost. Supporting documentation is required. A landlord who misses the deadline forfeits the right to withhold any part of the deposit for damages. Md. Code, Real Prop. § 8-203(g)(1)-(2), (j)
- Interest
- Simple interest at the daily U.S. Treasury yield curve rate for 1 year or 1.5% a year, whichever is greater. Interest is payable on deposits of $50 or more, not for part-months, and not unless the deposit is held at least six months. Md. Code, Real Prop. § 8-203(e)(1)-(3)
- How it's held
- In an interest-bearing account devoted exclusively to security deposits, at a federally insured financial institution doing business in Maryland. The deposit goes into the account within 30 days. Insured certificates of deposit and federal or Maryland securities are also allowed. The statute doesn't require the landlord to post a bond. Md. Code, Real Prop. § 8-203(d)(1)-(2), (i)(1)
- Penalty
- Up to three times the amount withheld, plus reasonable attorney's fees, if the deposit is kept without a reasonable basis. Charging a deposit above the cap exposes the landlord to up to three times the excess, plus fees. Md. Code, Real Prop. § 8-203(e)(4), (b)(3)
Rent increases in Maryland
- Notice to raise rent
- 60 days' written notice for a tenancy with a term of more than 1 week up to 1 month. 90 days for a term of more than 1 month. For a term of 1 week or less, 7 days with a written lease or 21 days without one. Send the notice by mail with a certificate of mailing, or electronically if the tenant elects it. Md. Code, Real Prop. § 8-209(b)
- Statewide cap
- None in the statute. The statute does bar an arbitrary rent increase as retaliation for protected acts. Md. Code, Real Prop. § 8-208.1(a)(1)(ii)
- City rent control
- No state ban found in the landlord-tenant sections. The notice section leaves in place any local law that requires additional notice or provides additional tenant protections. Md. Code, Real Prop. § 8-209(c)
