Patio Construction


Patios are considered open-air leisure areas. Structures built from brick, block, pavers, stone or concrete (masonry) are classified as patios.
 
Patios are usually built at grade. For construction of a patio built at existing grade (and less than 500 square feet), a permit is not required for construction. If the lot is served by a private well and/or septic, an at-grade patio must be reviewed by the Quality and Septic Systems Program to ensure that access for septic tank maintenance is provided.
 

Building Permit Requirements


If you intend to construct a patio over 500 sq. ft., a Building Permit is required, and site plans showing the existing and proposed structure location(s), including well and/or septic (if applicable), must be submitted. Structural plans also are required.
  
If the home is located in a subdivision with a Homeowner’s Association (HOA), a separate approval from the HOA may be necessary. Unless erected by the homeowner, all home improvement projects require that a licensed contractor by the Maryland Home Improvement Commission is used.
