Before You Build in Maple Grove, MN: Permit & Rule Checklist (2026)

In Maple Grove, fences in residential areas (not farms) may be up to 6 feet tall. Decorative front-yard fencing is capped at 3.5 feet and may not be an enclosure. Business and industrial fences may reach 8 feet, and fences within the 75-foot lakeshore setback may not exceed 5 feet.

Maple Grove does not require a building permit to install a fence. The city's Building Department handout states a building permit is not required for fences that do not exceed 7 feet. Fences are still fully regulated by the Maple Grove Zoning Ordinance (Sec. 36-816), so height, placement, and material rules apply regardless.

Under Sec. 36-816(a), a fence in Maple Grove must sit entirely on the owner's own property unless the adjoining owner agrees in writing to a fence on the division line. The city may require a registered land survey to establish boundaries. Fences must be kept in repair, and HOA covenants may impose stricter rules the city does not enforce.

Maple Grove has no standalone retaining-wall ordinance; walls follow the Minnesota State Building Code, which the city administers. Under Minn. Rules 1300.0120, no permit is required for a wall not over 4 feet (footing to top) unless it supports a surcharge or impounds Class I, II, or III-A liquids. Walls must also meet zoning setback and easement rules.

Maple Grove allows common fence materials such as wood (split rail, picket), brick, and chain-link, provided they are substantial and suited to the purpose (Sec. 36-816(b)). Front-yard decorative fences exclude chain-link, lakeshore-setback fences must be see-through and earth-toned, and chain-link tops may not have barbed ends.

Maple Grove regulates hot tubs under the same rules as pools. A permit is required when valuation exceeds $500, and the rules apply to any hot tub deeper than 18 inches or larger than 150 square feet. A hot tub with a lockable cover does not need a fence; otherwise the four-foot self-closing, self-latching barrier rules apply.

Maple Grove requires a building permit for any swimming pool or hot tub with a valuation exceeding $500. Any pool or hot tub deeper than 18 inches or larger than 150 square feet must comply with the city pool rules whether or not a permit is required. Plans, including a site plan and fence details, must accompany the application.

Maple Grove requires a fence around any regulated pool or hot tub as soon as it can hold water. Permanent fences must be at least four feet high, climb-resistant, with no more than four inches under the fence, and gates must be self-closing and self-latching with the latch at the top of the gate.

Beyond fencing, Maple Grove's pool rules require a 48-inch-wide deck around in-ground pools, handholds around the pool, engineered structural design, gratings on main outlets, fill spouts at least six inches above the rim, and lighting shaded away from neighbors. Pool noise equipment must be in the rear yard.

Maple Grove gives above-ground pools a fencing break: pools with side walls four feet or more in height need no separate fence, but access must be by a four-foot-high gate that is self-closing and self-latching. No deck is required for above-ground pools. The pool must still be at least five feet from lot lines.

Maple Grove's zoning code (Chapter 36) does not contain a dedicated accessory dwelling unit ordinance. Minnesota has no statewide ADU mandate, so a second independent living unit on a single-family lot is not a use the city's accessory-building rules authorize. Confirm options directly with Community & Economic Development.

New single-family homes must include a garage with capacity for at least two cars, no smaller than 20 feet wide by 24 feet deep. Attached garages count against the lot's accessory-building total (1,254 sq ft in R-1/R-2/R-3, with a 1,000 sq ft per-structure cap), which constrains converting required garage space to living area.

Detached sheds are accessory buildings. They cannot exceed 15 feet in height, must sit at least 5 feet from all lot lines, and cannot be in a front or side yard. In R-1, R-2 and R-3 districts the total per-lot accessory area is 1,254 sq ft, with no single detached structure over 1,000 sq ft. Most sheds need a permit.

Maple Grove's code does not single out carports with a separate standard; a roofed carport is treated as an accessory structure subject to the general accessory-building rules: 15-foot height limit, 5-foot setback from lot lines, no placement in a front or side yard, and the district accessory-area caps. New homes must still have an enclosed two-car garage.

Maple Grove's zoning code has no tiny-home or ADU category, so a tiny house used as a separate dwelling is not an authorized accessory use on a single-family lot. A site-built tiny home must meet the Minnesota State Building Code and minimum-dwelling standards; movable tiny houses on trailers are not permitted as permanent residences.

Open burning of natural vegetation (other than recreational fires) requires a city open burning permit under City Code Sec. 18-78, following Minnesota DNR guidelines. Burning leaves, grass, brush, garden debris and all non-vegetative materials is prohibited. Open burn fires must be 600 ft from any occupied structure on adjoining property and conducted only when winds are under 20 mph.

Maple Grove requires a free recreational fire permit (valid through December 31) for backyard fire pits. City Code Sec. 18-78 and the Fire Department policy set the limits: open-air fires no larger than 3 ft diameter by 2 ft high and at least 25 ft from combustibles; fires in metal/clay/concrete devices must be 15 ft from combustibles.

Maple Grove requires anyone performing tree care work in the city, including trimming and pruning for hire, to hold a tree care license issued by the City Forester. Companies applying chemicals must employ an ISA-certified arborist or someone with a forestry degree. The city does not publish a height limit for routine homeowner trimming of healthy trees.

Maple Grove regulates removal of significant trees through its Tree Preservation ordinance (Chapter 36, Article VII, Division 6). Removing trees eight inches DBH or larger can require a certified tree survey, a preservation plan, and replacement plantings. Diseased, dying, or dead trees may be exempt when confirmed by a certified arborist or the community development director.

Maple Grove enforces year-round outdoor watering rules on its municipal water system: no sprinkling from 10 a.m. to 6 p.m. any day, plus an odd-even schedule by address tied to the calendar date. New sod or seed may qualify for a temporary exception. State law requires rain sensors on new irrigation systems.
