A site plan may look like a simple drawing of a property, but the measurements behind it can affect the entire permit process. In Baltimore, land surveying provides important site information that designers and property owners can use when preparing plans for construction. This becomes especially important when proposed work sits near lot lines, changes grades, or adds a new structure. Starting with reliable measurements gives the design team a stronger picture of existing conditions before plans reach city reviewers. What Baltimore Requires on a Site Plan Baltimore's building code requires construction documents submitted with a permit application to include a site plan, subject to certain exceptions or modifications. The city also specifies what that site plan needs to communicate. The plan must show the size and location of new construction and existing structures to scale. It must show distances from lot lines, established street grades, and proposed finished grades. Applicab...
Adding space to a rowhouse can look straightforward on architectural drawings. Once construction begins, however, the location of new walls matters just as much as their design. A land surveyor can play a key role at this stage because certain projects require a wall check before construction can move forward. This requirement can catch property owners by surprise, especially in a city where rowhouses often sit close to property lines and neighboring structures. Understanding the wall-check process early can help owners, builders, and designers prepare for this part of the project. What Is a Wall Check? A wall check is a specific type of land survey used during construction. The DC Department of Buildings describes it as a survey that locates certain types of new construction and compares their positions with property lines and the approved building permit documents. An independent Registered Land Surveyor performs the work, measuring the location of foundation walls, certain retaining...
