Full Breakdown
Zoning Ordinance Section 2.304(F) sets the accessory-structure rules for Pontiac's R-1 one-family district. Height is limited to 15 feet, measured midway between the roof peak and the eaves; living space built above an attached accessory structure instead follows the principal building's height limit. The combined footprint of all accessory buildings on a lot cannot exceed 15 percent of the total lot area, the first-floor area of the house, or 800 square feet in R-1 (900 square feet in R-1A and R-1B), whichever figure is smallest.
An attached accessory building counts as part of the principal structure and must meet that structure's own setbacks. A detached accessory building is barred from any required front or side yard and may only go in the rear yard, set back at least 3 feet from any lot line; on a corner lot it must instead meet the side-street setback that applies to the principal building, and on a through lot no part of it may sit closer to the rear lot line than the principal building's required setback.
Section 2.304(F)(4) caps the total at two accessory structures per residentially zoned lot, within that same area limit. The Community Development Department's building official reviews accessory-building permits and site compliance, and Section 6.703 bars occupancy of any structure until the building official signs off on final inspection.
Violations & Fines
An oversized, misplaced, or unpermitted shed is enforced as a municipal civil infraction under Zoning Ordinance Section 6.706, not a criminal matter. The building official issues the infraction after investigation; the minimum civil fine is $100 plus costs, climbing to at least $250 for a first repeat violation of the same rule and $500 for any later repeat, with each day of continued violation a separate offense.
