Rockford’s own rules

  New homes, additions, patios, decks, porches, garages, accessory buildings, and fences inside Rockford city limits (not interior remodeling, roofing, window replacement, or siding).

  • Permit is not required for interior remodeling, roofing, window replacement, or siding, per 155.03.
  • Construction may proceed only after the permit is issued.

  “no building or other structure shall be erected or altered within the city without first receiving a permit. a permit is required for work such as new homes, additions, patios, decks, porches, garages, accessory buildings, or for work that would change the outside dimensions of an existing building. a permit is not required for interior remodeling, roofing, window replacement, or siding a building.”

• Local zoningPresent (with conditions)

  Land inside Rockford city limits under the city's Chapter 155 restricted residence district (city-wide except the business and industrial areas named in 155.14). This is the city's own ordinance, not county zoning.

  • 155.14 carves out a business district strip along Main Avenue, certain lots in blocks 11 and 16, and an industrial area west of 7th Street NW north of West Main Avenue.
  • 155.15 requires a council special use permit for non-residential buildings in the district, which needs a three-fourths council vote.
  • 155.17: no special use permit when 60% of residential owners within 300 feet object, except by unanimous council vote.
  • Only the 2020 code version was read; later amendments were not checked.

  “155.14 restricted residence district. the following area is hereby defined and established as a restricted residence district: all that area lying within the corporate limits of the city except the following described area: business district: territory adjacent to and with ½ block of either side of main avenue from fourth street east to third street west; also lots 6 and 7, block 16 and lots 16 - 30, block 11 industrial: west of seventh street nw and north of west main avenue”

• Zoning districtsPartial

  Districts defined in Rockford city's Chapter 155 text (no zoning map located).

  • The code defines one restricted residence district plus business and industrial carve-outs by text description; no map was located in the code read.

  “business district: territory adjacent to and with ½ block of either side of main avenue from fourth street east to third street west; also lots 6 and 7, block 16 and lots 16 - 30, block 11 industrial: west of seventh street nw and north of west main avenue”

• Minimum dwelling sizeSpecified

  Dwellings in the restricted residence district inside Rockford city limits.

  • The 22-foot rule is a minimum width measured at the narrowest point, excluding attached garages, porches and accessory structures.

  minimum dwelling dimension (narrowest point): >= 22 feet (attached garages, porches, and other accessory structures excluded)

  “no dwelling shall be erected, placed, or occupied within the restricted residence district unless such dwelling shall have a minimum dimension of 22 feet measured at the narrowest point of such dwelling. said dimension shall be exclusive of attached garages, porches or other accessory structures.”

• SetbacksSpecified

  Main single-family residential district: the city's restricted residence district under Chapter 155. Applies to principal buildings in that district.

  • 155.19 front-yard exceptions: item 2 allows a closer front setback where a building exists on one side within the same block; item 3 sets the front yard on the address side for double-frontage lots.
  • Accessory-building setbacks in 155.23 were not read.

  front yard: >= 25 feet (155.19 exceptions 2 and 3) · side yard: >= 6 feet (measured from the drip line of the building) · rear yard: >= 20 feet

  “within the restricted residence district there shall be a front yard of not less than 25 feet (measured from the front lot line)”

• Off-grid sanitationLimited

  Private on-site sewage disposal inside Rockford city limits.

  • Chapter 98 bars on-site systems except as provided in the chapter; 98.02 requires an approved on-site system where no public sewer is available.
  • Public sewer connection is required where available (see utility connection claim).

  “except as otherwise provided in this chapter, it is unlawful to construct or maintain any on-site wastewater treatment and disposal system or other facility intended or used for the disposal of sewage.”

• Mandatory utility hookupSewer (with conditions)

  Building sewers for buildings inside Rockford city limits where the public sanitary sewer is available.

  • Sewer connection is ordered by the city under the 96 chapter and the connection notice forms; the availability distance under 95.05 was not read.
  • Connection must be completed within 60 days after the sewer permit is issued, subject to hardship extensions.
  • Water connection requirement was not verified (chapter 90 not read).

  “the permit shall require the owner to complete construction and connection of the building sewer to the public sewer within 60 days after the issuance of the permit, except that when a property owner makes sufficient showing that due to conditions beyond the owner's control or peculiar hardship, such time period is inequitable or unfair, an extension of time within which to comply with the provisions herein may be granted.”

• Building in a floodplainRequired

  Flood plain development inside Rockford city limits on lands covered by Chapter 160.

  • Applies to any manmade change, including placement of factory-built homes, within the chapter's flood plain lands; 160.04 (lands covered) was not read.

  “160.12 flood plain development permit required. a flood plain development permit issued by the administrator shall be secured prior to any flood plain development (any manmade change to improved and unimproved real estate, including but not limited to buildings or other structures, mining, filling, grading, paving, excavation or drilling operations) including the placement of factory-built homes.”

• Permit processPartial

  Building and land use permits filed with the city building official inside Rockford city limits.

  • 155.02 makes the building official responsible for administering chapter 155.
  • 155.04 lists the application content; the fee (155.05), approval/denial (155.08-155.09), and conditions (155.10-155.11) were not read, so the process is partial.

  “155.02 building official. the building official is responsible for the administration and enforcement of this chapter.”
