TNV (Technical and Numeric Variation)
Written and verified by Struqt’s registered architects · Last verified July 2026
Address-specific overrides applied on top of the zone's default rules. TNVs change the effective height limit, setbacks, site coverage, or minimum lot for your particular parcel. Every designer must check them before sketching anything.
