Summary
Dallas requires every outside light fixture in the city to pair its light source with a reflector so the beam stays controlled and is never aimed across a property line. Sec. 51A-6.104(b) of the Dallas Development Code makes this a citywide environmental performance standard, enforced the same way as the code's noise and vibration limits under Chapter 51A.
(b) Outside lights must be made up of a light source and reflector so that acting together, the light beam is controlled and not directed across a property line. (Ord. Nos. 19455; 19995)
Full Breakdown
104 sits in Article VI of the Dallas Development Code, the same article that sets the city's noise limits (Sec. 102), vibration limits (Sec. 105) and odor/particulate rules (Sec. 106). Subsection (b) is Dallas's shielding mandate: outside lights must be made up of a light source and reflector so that, acting together, the beam is controlled and not directed across a property line. The requirement is written as a design standard, not a discretionary lighting plan review, so a fixture either meets it or it does not; there is no separate outdoor-lighting permit application layered on top.
It applies to any use, in any zoning district, because Chapter 51A's environmental performance standards are not confined to specific districts the way setback or height rules are. Subsection (a) of the same section, covered on its own page, separately bans glare or direct illumination that crosses a lot line and creates a nuisance, so a fixture can still fail (a) even when it technically carries a shield if that shield doesn't stop the spill. Nonconformance is addressed in Sec. 107: a lighting installation that predates the current standard may keep operating, but it may not be enlarged or remodeled in a way that increases its noncompliance.
104 the same way it enforces every Article VI standard, under the citywide enforcement mechanism at Sec. 103, which reaches any use or structure in Dallas regardless of the underlying zoning classification.
Violations & Fines
A knowing violation of Sec. 51A-6.104(b) is enforced under Sec. 51A-1.103: each day the unshielded fixture keeps operating is a separate offense, punishable by a fine of not less than $200 nor more than $2,000. The minimum fine doubles on a second conviction for the same violation within 24 months and triples on a third or later conviction in that window. The building official or another city representative may pursue criminal prosecution, civil court action, or order utility disconnection until the fixture is brought into compliance.
