The Democracy in Design Act directs the General Services Administration (GSA) to ensure that all federal public buildings follow the "Guiding Principles for Federal Architecture," a set of design standards originally established in 1962. The bill requires the GSA Administrator to create new regulations within 180 days that implement these architectural principles and establish minimum design standards for federal buildings across the country. The legislation affects federal agencies and the public by promoting consistency and quality in how government buildings are designed and constructed. The bill does not specify new funding but places an administrative requirement on the GSA to enforce existing architectural standards through formal rulemaking, which must include public comment periods.
