After a code is adopted, the code's success or failure is impacted by the local building industry's ability and willingness to comply with the new code requirements. Through the use of innovative legislation tied to the energy codes, some states and cities have been able to further encourage and improve compliance.

Local jurisdictions and states aiming for greater gains in energy efficiency can capitalize on consumer and builder preferences for sustainable home designs. Local jurisdictions have the power to prioritize plan review for homes that have the most energy efficiency potential. In turn, homebuilders are rewarded with quicker sales and given positive market signals for building the most efficient buildings on the market.
Energy codes generally apply to new construction as well as to major renovations of existing buildings. It is becoming apparent that energy codes are not widely enforced in existing buildings, consequently neglecting a significant opportunity for energy improvements. However, there are portions of the current energy code that are relatively easy to implement in existing buildings (outside of major renovations) and deliver cost-effective energy savings. Some states and cities have made progress on improving the energy efficiency of their existing building stock through "point of sale" or "time of transfer" requirements. Generally, these ordinances target buildings when they change ownership and require the property owner to make some basic energy efficiency improvements or meet set standards before sale. Legislation applicable to rental properties also offers another opportunity to improve the energy efficiency of the existing housing stock. Point-of-sale legislation is a recent but promising strategy to effectively leverage energy codes to achieve energy and carbon reduction.
States can requires new residential buyers to receive information on how home meets, falls below, or exceeds the national model code.
