Portland, ME Landscaping Rules: Artificial Turf (2026)

Portland's Code does not contain a residential artificial-turf ban. The most direct reference is in Chapter 34 (Landcare), Sec. 34-5(a)(4)(iii) and 34-5(b)(3)(ii), which carve out 'Hadlock Field' from the citywide synthetic-pesticide and fertilizer prohibitions — confirming that the Sea Dogs' artificial-turf playing surface is treated specially. For private residential installations, Chapter 14 (Land Use, Portland's zoning code) governs lot coverage and landscaped open space; landscaped open space generally excludes 'impervious surfaces such as paved or gravel driveways, parking areas, walkways, and patios.' Artificial turf is typically treated as semi-impervious in zoning calculations and may not count toward open-space requirements. Because Portland has a robust pesticide and fertilizer ban under Chapter 34, some residents install artificial turf to avoid lawn-care obligations; this is permitted as long as drainage does not create a nuisance to abutters and the installation complies with shoreland zoning if within 250 ft of a protected water body (38 M.R.S. § 435).
