Summary

New Haven's zoning code defines artificial turf as an impervious surface, not a pervious one, so installing it in a yard counts against the lot's maximum impervious coverage limits, not toward open, permeable ground.

PERMEABLE or PERVIOUS means surfaces which allow for the percolation of water into the underlying soil. Permeable surfaces include but are not limited to grass, mulched groundcover, planted areas, permeable paving as well as porches and decks erected on pier foundations that maintain the covered lot surface's water permeability. Pervious surfaces do not include any structure or building, any porch or deck that limits the covered lot surface from absorbing water, or any outdoor stairs, on-grade surface sports court, swimming pool, artificial turf, sidewalk or patio constructed of concrete, asphalt, brick, compacted gravel or other material that impedes the infiltration of water directly into the subsurface of the lot.

PODIUM CONSTRUCTION means a construction method that divides a building into lower and upper portions for which the lower portion, the "podium", is one or two stories that are built of a robust structural system, such as steel or reinforced concrete. The upper portion, which may be a maximum of five residential stories or six business stories, according to the International Building Code (IBC), is built of a more economical structural system, such as wood light frame construction (WLFC). The horizontal separation created by the podium is deemed to be "grade" for the purposes of determining the number of stories that can be built above the podium.

Full Breakdown

Section 1 of the New Haven Zoning Ordinance defines 'Permeable or Pervious' surfaces and expressly lists artificial turf alongside concrete, asphalt, brick and compacted gravel as material that blocks water from infiltrating the soil, meaning it does not qualify as pervious ground. That distinction matters under the district bulk tables: RS-1, for example, caps total building and paved area at 70% of the lot under Section 11(a)(1)g. A homeowner who lays artificial turf in a yard cannot count that area as permeable open space; it is treated as impervious coverage and can push a project over the district's maximum.

Violations & Fines

The Zoning Enforcement Officer can order a stop-work or deny a certificate of occupancy for noncompliant coverage under Section 62; unresolved violations may draw an injunction or civil penalties.

Frequently Asked Questions

Can I install artificial turf in my New Haven yard?
Yes, but it counts as impervious surface under Section 1, so it applies toward your lot's maximum building-and-pavement coverage, not toward required permeable ground.
Does turf count toward New Haven's stormwater rules?
Yes. Section 60 requires a stormwater management plan for many projects, and impervious surfaces like artificial turf factor into the runoff and infiltration calculations it must address.
