Residential Estimator allows you to adjust the cost for the additional construction needed to meet seismic building code requirements. For frame homes, this includes the additional cost of structurally upgrading the sheathing, bracing and roof ties and of increased reinforcement in the foundation. For masonry homes, this includes the additional reinforcement cost for both the exterior wall and foundation, as well as the additional costs for roof ties and any other miscellaneous structural upgrading.
To set a seismic zone, select one of the zones listed on the form, or select None (No Adjustment, which is Zone 0).
