Fairfax, VA Landscaping Rules: Composting (2026)

Backyard composting of yard waste and kitchen scraps is permitted in the City of Fairfax without permit for residential use. The city encourages composting as part of its sustainability and waste reduction goals, and composting reduces methane emissions from landfills while producing beneficial soil amendment. Compost bins or piles must be maintained to avoid public nuisance, meaning they should not produce offensive odors perceptible at the property line, should not attract rodents or flies, and should not cause drainage or runoff problems to neighboring lots. Best practices include maintaining a 30:1 carbon-to-nitrogen ratio by mixing brown materials (leaves, straw, cardboard) with green materials (grass clippings, vegetable scraps), turning the pile regularly to maintain aerobic conditions, and keeping moisture like a wrung-out sponge. Avoid adding meat, fish, dairy, oily foods, pet waste, and diseased plants to backyard bins. The City of Fairfax provides curbside yard waste collection for residents, and leaf collection operates seasonally in the fall. Residents can also take yard waste to designated drop-off sites. Commercial composting operations processing off-site materials require a Virginia DEQ solid waste permit under 9 VAC 20-81. HOAs may impose additional rules on compost bin visibility and location, particularly in townhome communities. Worm bins (vermicomposting) are allowed indoors and on patios without restriction.
