Residential Building Plans
Building plans are a graphical representation of what a proposed building will look like after construction. They are typically used by builders and contractors to construct buildings and can include site plans, foundation plans, floor plans, and building elevations and many others. Anyone who is constructing a new building, adding on to an existing building, remodeling an existing building, changing the occupancy and use of an existing building or space will need to submit building plans for review.
For new houses or addition over 500 square feet, state law requires foundation plans sealed by a Texas Professional Engineer.
A complete set of building plans should be drawn to scale and will include:
- A site plan, drawn to scale.
- Building floor plans, drawn to scale, including braced wall locations and engineered foundation for homes or additions over 500 square feet.
- Mechanical plans for the heating, ventilation or air conditioning system.
- Electrical plans for the electrical system.
- Plumbing plans for plumbing system.
- Energy code compliance information for the building envelope, lighting or mechanical systems.
- The Plat should be the legally recorded plat and include the recording information as well as a certified copy stamp.
- The Energy Code Documents must be either an Energy Star Report or IC3 report available from the Texas Energy System Laboratory software.
