Artificial turf in Mountain View, CO, and the permit a visible yard needs.

If the street or the alley can see your turf, it needs a permit.

Mountain View is twelve blocks between Sheridan Boulevard and Fenton Street, from W 41st to W 44th Avenue (Town of Mountain View). It has been a town of its own since 1904 (Wikipedia), even with a Denver mailing address, and its zoning code is the one your yard answers to.

Since Ord. 2020-07-20A, that code has made it unlawful to install or reinstall artificial turf in a residential front yard, side yard, or rear yard visible from public right-of-way without an artificial turf permit (Mountain View Municipal Code 16.02.110). The code counts alleys as public right-of-way (Municipal Code 16.01.090), so a back yard seen from the alley needs the permit as surely as a front lawn. A side or rear yard hidden from view needs none, and the town's standards serve there as advisory guidelines.

Whether a yard is hidden is the town's call. The fence rules call a fence screened when it is at least 6 feet tall with picket gaps no wider than 20% of a board's face, but in the code as posted on 12 September 2026 the turf rule cites subsection (f), the sidewalk setback, rather than (g), the screening test (Municipal Code 16.04.040 and 16.04.045). Get the town's planning and zoning staff to confirm in writing that your yard can't be seen.

Four things go to the Town Clerk.

The form goes to the Town Clerk (Municipal Code 16.02.120). First, the fee: Town Council sets it by resolution, so ask Town Hall at 4176 Benton St., 303-421-7282, for the current amount and the form. Town Hall is open Monday to Thursday (Town of Mountain View).

Second, two copies of a scaled site plan showing property lines, access and the drive, and the buildings, landscaping and turf, both existing and proposed. The measurements from our free visit and the layout you approve give you the shapes and dimensions to draw.

Third, the manufacturer's documentation: a specification sheet, installation instructions, and the maker's written coverage of at least eight years against color fading and loss of pile height. Ask for it with the sample. Fourth, anything else the Zoning Administrator asks for. To talk the plan through first, the town offers free Design Review Committee meetings (Town of Mountain View Building Department).

The code sets a floor for the turf and the ground under it.

Turf in view must be cut pile with infill, made of polypropylene, polyethylene or a blend, with a pile at least 1.25 inches tall and a face weight of at least 50 ounces per square yard. Plastic or nylon carpet used as outdoor turf is prohibited (Municipal Code 16.04.045(d)). Check both numbers on the specification sheet first.

The ground is specified too: a compacted, porous base, graded and drained against runoff and flooding, turf anchored permanently with nails and glue, and a solid barrier such as a concrete mow strip or bender board at the planting beds. Our site prep and base are built for your soil, and the turf is laid, seamed and edged.

Afterwards the turf has to look naturally green and stay free of weeds, debris, stains, tears, holes, impressions and odors, with infill such as silica granules or cleaned sand and rubber brushed into the fibers. For a dog run the alley can see, stains and odors are a code matter. Our walkthrough covers the care it needs.

Older turf and new houses follow their own rules.

Turf laid legally before these standards can stay even if it falls short of them. It can be repaired, or changed to fit the rules better, but not enlarged, expanded or extended. Once 50% or more of it is damaged or removed and replaced with new turf, the replacement must meet every standard (Municipal Code 16.04.045(d)). In view of a street or alley, that reinstall needs the permit.

A new house changes the sums. Where a new primary residential structure is being built, 30% of the lot must be permeable landscaped area and 70% of the required landscaping in the front and side yards must be living material. Artificial turf is not living material and can't count, and the front setback needs living landscaping and a tree before a certificate of occupancy. R-3 lots follow the same wording (Municipal Code 16.05.045). Lay the turf out around that planting, not over it.

Your water district ends lawn watering after 30 September.

The Wheat Ridge Water District supplies and bills Mountain View's water (Town of Mountain View). It is one of Denver Water's Master Meter distributors, with its own system and its own customer rates (Denver Water), so its board decides how Denver Water's drought rules apply here.

The board chose to follow Denver Water's end to the season. 30 September 2026 is the last day for lawn watering, and from 1 October all lawn watering and lawn spray irrigation are prohibited. Trees, shrubs, perennials and vegetables can still be hand-watered with a shutoff nozzle or given low-volume irrigation, but not between 10 a.m. and 6 p.m. (Wheat Ridge Water District).

The district grants no variance for new seed or sod during the drought, and repeat violations can bring fines of up to $1,000 each time (Wheat Ridge Water District). Household use above 6,000 gallons a month carries a drought surcharge through 30 April 2027 (Wheat Ridge Water District). Before you budget for a rebate, read our guide to Denver-area water rebates and ask the district.
