Last updated: Verified:
Comprehensive guide to Maryland zoning laws, building codes, and land use regulations.
Key Facts
- Building Code: Maryland Building Performance Standards (based on 2021 IBC)
- State ADU Law: Yes — ADU-friendly
- ADU Details: HB 1337 (2024) requires counties and municipalities to permit accessory dwelling units on lots with single-family detached homes. The law limits local governments from imposing overly restrictive requirements such as additional parking mandates, owner-occupancy conditions, or minimum lot size thresholds that would effectively prohibit ADU construction.
