Noise Abatement Ordinance
(NAO)

Build­ing zones for build­ings with rooms sens­it­ive to noise that have not yet been de­veloped when the Act comes in­to force may only be de­veloped to the ex­tent that the plan­ning val­ues are com­plied with or can be com­plied with by a change in the type of use, or by plan­ning, design or struc­tur­al meas­ures. The en­force­ment au­thor­it­ies may grant ex­cep­tions for small sec­tions of build­ing zones.
