Artificial turf on a custom home build: where it fits in the landscape plan, the approvals, and when it goes in

01Where does turf fall in a custom build’s schedule?

Near the end. A common order:

1. Design. The landscape architect or designer draws the turf areas while the house plans are in review. Range View Estates in Mead lets a landscaping plan go in with the construction drawings, though it must be approved before any landscaping starts (declaration).
2. Rough grading, foundation, backfill and utilities, by the builder.
3. Final grading, signed off. In unincorporated Larimer County, the final inspection a CO waits on is made after finish grading (Larimer County).
4. Hardscape and structures: patios, walls, a pool or an outdoor kitchen, with irrigation sleeves and lighting conduit laid under them before the concrete. The order among those trades is in planning a backyard around artificial turf.
5. Drip lines for beds and trees, then the trees and large plants, while machines can still cross open ground.
6. Turf base and turf, last, so nothing heavy drives over it.

Turf is last because its base is dug to the finished grade and meets every edge already built. Base depth: what base goes under artificial turf. Season: when to install artificial turf.

02Does the town review turf in a custom home’s landscape plan?

Mostly not at the building permit, though some town rules still reach the yard:

Berthoud and Mead also ask no landscape plan with a single-family permit. Firestone wants a town permit before any artificial turf goes in, and Loveland says the state’s turf law doesn’t apply to single-family lots. Every town is in our guide to artificial turf rules in Northern Colorado.

Statewide, since January 1, 2026, local governments may not allow nonfunctional artificial turf in new development on commercial, institutional and industrial property, HOA common areas, and streets and medians; single-family lots aren’t on that list (SB24-005). By January 1, 2028, every town and county with zoning power must also regulate live turf grass in new residential development, each choosing its own standard (HB25-1113), so a long build may see new rules. Not legal advice.

03What does the HOA or metro district review, and on what clock?

Custom-home communities review the yard much as they review the house:

• A professional plan. Monte Cielo in Longmont requires a professionally prepared landscape plan and highly encourages a landscape architect (guidelines). Range View Estates wants a professional landscape designer or contractor, and its plans must show any artificial turf, plus a drainage and grading plan that coincides with the builder’s.
• Detail. Heron Lakes in Berthoud asks for grading contours at 1-foot intervals reaching 10 feet past the lot lines, and each landscape feature’s size, material and details or cut sheets (rules).
• Unposted rules. Emerald Estates in RainDance gives out its design guidelines through the neighborhood’s broker (Emerald Estates); get them before design starts.

Many deadlines count from the CO or the end of construction, and some hold money until the yard is done:

Golf communities add their own calendar. Heron Lakes allows no outside construction during its golf tournament week, normally in July, and contractors reach a lot through the front only. The Masters keeps staging off district land and neighbors’ lots and limits visible rock and soil piles to 30 days, which decides when base rock can arrive.

Colorado law bars an HOA from prohibiting artificial turf in a detached home’s backyard, but the committee still reviews the design, and front yards aren’t protected (SB23-178). The packet: HOA approval for artificial turf.

04How do grading, irrigation and turf fit together on the plan?

• Grading. The turf base follows the engineered grade instead of reshaping it; The Masters bars landscape elements that disturb it and any change to engineered swales. The Colorado Geological Survey lists poor surface drainage near foundations among the landscaping problems on expansive soils (CGS). More in artificial turf on clay soil.
• Irrigation. Turf needs no spray heads, but trees in or beside it still need water, usually by drip (watering trees). CSU Extension says to group plants with similar water needs in one hydrozone (CSU Extension); turf simply stays off the zone map, unless a zone is kept to rinse a dog area (sprinklers after turf).
• Edges. Where turf meets a patio, walk or pool deck, the finish grade must leave room for the base so the turf sits flush. See edging options.
• Glass. Big windows can reflect enough sun to melt turf. Where screening isn’t wanted, the Synthetic Turf Council recommends planted areas or hardscape where the reflected heat lands (STC); more in turf melting near the house.
• Features. A putting green’s contours are shaped with the grading, not after it (putting greens, putting green design).
• The product. Colorado has barred installing artificial turf with intentionally added PFAS since January 1, 2026 (SB24-081), so put the spec sheet and its PFAS documentation in the review packet (what a spec sheet should say).

05What if the house is finished in winter?

Then the CO and the yard can come apart. In unincorporated Larimer County, a Temporary CO may run 180 days once life-safety items are corrected, for a $600 fee that is partly refundable. Where Wellington’s landscape standards apply, landscaping goes in before the CO, or the developer posts security of 125% of an approved cost estimate if weather prevents it; those standards are written for subdivisions and site plans, so for one custom house, ask Wellington Planning.

HOA clocks often allow for winter, as Range View Estates’ October 1 date does. If a deadline lands before the ground is workable, ask the committee for an extension in writing before it passes. How long the work takes: how long turf installation takes.

06What should I ask the builder, designer and installer?

• Builder: “Who signs off the final grade, and can I have the drainage certificate or as-built grades before turf work starts?” A good answer names the document and a date.
• Landscape architect or designer: “Does the plan show a base section for the turf, where its water drains, and the edge at each patio and walk?” A good answer is a detail drawn on the plan, not a note.
• Installer: “What has to be finished before you start, and how will material reach the backyard?” A good answer: final grade signed off, hardscape and sleeves done, trees planted, and an access route the HOA allows.
• All three: “Who prepares the HOA packet and tracks the deadline?”

More in questions to ask a turf installer and checking that the base went in; the work itself is artificial turf installation, and larger lots are in turf on acreage and estate lots.
