Before You Build in Springfield, IL: Permit & Rule Checklist (2026)

Illinois has no residential shared fence cost statute. Each property owner is responsible for their own fence. Agricultural boundary fencing has separate rules.

Springfield caps fences in a required front yard at 4 feet (and they must be at least 50% open), limits residential fences to 6 feet overall, and allows up to 8 feet in commercial and industrial districts. Recreational fences (tennis, baseball backstops, etc.) may be taller with a permit.

Any fence over four feet tall in a residential, commercial, or industrial district requires a fence permit from the Office of the Zoning Administrator (Building & Zoning Department), at a cost based on the standard building permit fee. No work may start until the permit is issued, and the permit becomes void one year after issuance if the fence is not completed.

Springfield requires permits for retaining walls above a certain height, typically 4 feet. Engineering review may be required for taller walls.

Springfield requires pool barriers meeting safety codes to prevent drowning. Fences must be at least 4 to 5 feet tall with self-closing, self-latching gates.

Where a dwelling wall serves as part of the pool barrier, doors with direct pool access must have a UL 2017 audible alarm. Suction outlets must meet ANSI/APSP-7 anti-entrapment standards, all pool metal must be bonded, and receptacles within 20 feet must be GFCI-protected.

No Springfield-specific ordinance separately regulates hot tubs or jacuzzis. Illinois' Private Swimming Pool Enclosure Act expressly excludes jacuzzis from its 'swimming pool' definition, so the state perimeter-barrier mandate does not apply to them, though general permit, electrical, and entrapment rules still govern installation.

A building permit and site plan are required for every Springfield swimming pool and its fence, and a setback inspection must be completed before the pool permit is issued. Permit review can take up to 14 days, and no work may begin until the application is approved.

Every Springfield swimming pool capable of holding water deeper than 24 inches must be surrounded by a minimum 48-inch-high barrier with no more than a 2-inch gap at grade and openings that will not pass a 4-inch sphere. Pedestrian gates must open outward, be self-closing, and self-latching.

When an above-ground pool structure (or a barrier mounted on it) is the barrier and access is by ladder or steps, the ladder must be removable, securable, or surrounded by a compliant barrier. Illinois exempts above-ground pools 42 inches or taller from the state enclosure mandate.

Springfield's zoning code expressly prohibits using any detached garage, accessory building, or structure as a dwelling unit, so a freestanding accessory dwelling unit (ADU) is not permitted under Zoning Ordinance Section 155.068(b)(2). Illinois has no statewide ADU law in force (HB 1813 remains pending), so the local ban governs.

Springfield's zoning code bars converting a detached garage or accessory building into a dwelling unit or a business: Section 155.068(b)(2) states no portion of such a structure may be used as a dwelling unit or for any business or office use. Converting an attached garage into living space is treated as altering the principal building and requires a permit.

Springfield Zoning Ordinance Section 155.068 allows detached sheds and accessory buildings in the rear yard, requiring at least a 3-foot setback from any property line, a 6-foot separation from the principal building, and an 18-foot maximum height in residential districts. Section 155.062 lists accessory sheds among permitted rear-yard obstructions.

Springfield requires permits for carport construction. Setback requirements, height limits, and lot coverage maximums apply.

Springfield regulates tiny homes differently based on whether they are on a permanent foundation or on wheels. Zoning and minimum square footage requirements apply.

Springfield treats backyard fire pits as recreational fires under Chapter 94 of the city code (which adopts the International Fire Code). The Fire Safety Division requires fire pits to be located 25 feet from any structure or combustible materials (15 feet for portable outdoor fireplaces), capped at a 3-foot diameter and 2-foot height, burning only dry wood or charcoal.

In the City of Springfield, open burning of yard waste, garbage, and construction materials is prohibited. Only recreational fires (fire pits, portable fireplaces) using dry wood or charcoal are permitted under Chapter 94 and the adopted International Fire Code, subject to size, setback, attendance, hours, and wind conditions. Outside the city, Sangamon County allows landscape/agricultural waste burning under conditions.

No Springfield-specific ordinance directly imposes routine lawn-watering restrictions (odd/even days, time-of-day limits). The municipal water utility, City Water, Light & Power (CWLP), supplies Springfield from Lake Springfield and currently has no standing outdoor-watering ban; restrictions would only be imposed by CWLP if drought conditions required them.

Springfield City Code Title IX, Chapter 99, Article III, Section 99.20 ('Trimming; nuisance') declares it a nuisance when limbs and foliage of trees on premises abutting a street, alley, or sidewalk are not trimmed at least 10 feet above a sidewalk and 15 feet above any street or alley. The abutting owner, occupant, or person in control must trim them, and the city may do the work and recover the cost if the owner fails to comply.

Springfield regulates tree removal on private property through permits and size thresholds. Street trees are city-managed and cannot be removed by residents.
