Molding
Molding refers to ornamental strips of material, such as wood, used to cover joints between walls and ceilings, and to trim door and window frames. It adds a decorative touch to interiors and can significantly enhance the aesthetic appeal of a space.
Notice of Completion
A legal notice filed after the completion of construction that signals the time frame during which an unpaid contractor can legally file a mechanic’s lien.
Off-Site Costs
Expenditures related to construction that are spent away from the place of construction. Off-site costs can include expenses associated with extending utilities and infrastructure needed to service a development project.
Oriented Strand Board (OSB)
Oriented Strand Board (OSB) is a building material composed of rectangular-shaped wood strands arranged in layers at right angles to one another, forming a strong and stiff panel bonded with waterproof adhesives.
Overbuilding
Overbuilding occurs when there is more real estate construction in a specific area than the market can absorb within a reasonable amount of time. This imbalance between supply and demand often leads to vacant properties and lower rental rates.
Permit
A permit is a vital document issued by a government regulatory authority that grants the bearer the right to perform specific activities such as constructing, modifying, or occupying a building.
Pitch
In real estate, pitch primarily refers to the slope or angle of a roof, which can greatly influence the property's design, function, and appeal. 'Pitch' can also denote a thick black substance used in construction and maintenance, such as driveway pavement or roof patching.
