New Haven's Outdoor Lighting: The Rules That Matter
Every city handles outdoor lighting a little differently. In New Haven, Connecticut, there are 2 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.
Dark Sky Rules
New Haven's exterior lighting rule requires all outdoor light sources to aim downward, caps color temperature at 3000 Kelvins, and limits height to 20 feet to cut light pollution and glare.
Key details: Governing section: Zoning Ordinance § 60.1. Color temp cap: 3000 Kelvins maximum. Height cap: 20 feet without review. Direction rule: light must aim downward.
Installing exterior lighting that exceeds 3000K color temperature, is aimed upward without shielding, or exceeds the 20-foot height cap without site plan review violates Section 60.1 and can hold up a zoning approval.
Light Trespass & Shielding
New Haven requires every outdoor light fixture in a parking lot, driveway, or pedestrian area to be full cutoff or fully shielded so the light source itself stays hidden from view.
Key details: Governing section: Zoning Ordinance § 60.1(d)(2). Required fixture type: full cutoff or fully shielded. Applies to: parking, driveway, pedestrian lighting. Closing curfew: 50% dim within 30 min.
A parking lot or security fixture that exposes the bare bulb instead of a full cutoff or fully-shielded housing violates Section 60.1(d)(2) and must be replaced or retrofitted.
The Bottom Line
New Haven's outdoor lighting rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming New Haven is broadly strict or permissive.
Keep in mind that New Haven can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
