Violations & Fines

Exceeding a district's lot coverage cap is enforced under § 59-4350: every owner, lessee or other person who maintains the violation, and anyone who assists in it, is individually guilty of a separate offense, and each day the excess coverage continues is its own violation. A first or second conviction is a Class "a" offense, punishable under § 1-6 by a fine of up to $500.00, excluding costs and fees; a third or later conviction becomes a Class "b" offense, carrying a fine of up to $1,200.00 plus costs, up to six months in the City Jail, or both. The Director may also bring a court action under § 59-4350.3 to compel removal or correction of the excess construction.

Frequently Asked Questions

What is the maximum lot coverage in Oklahoma City's R-1 district?

Table 6100.2 of § 59-6100 caps residential lot coverage in the R-1 Single-Family Residential District at 50 percent, meaning principal and accessory buildings together cannot cover more than half of the lot; the rest is also subject to the district's separate front, side and rear yard setbacks.

Can I exceed my district's lot coverage limit with a variance?

Yes, but only through the Board of Adjustment's variance process under § 59-4250, which requires proof of an unnecessary hardship or exceptional practical difficulty peculiar to the property; the Board may grant only the minimum relief needed and can attach conditions in its order.

How is lot coverage different from a setback?

Lot coverage, defined at § 59-2150, measures the percentage of the whole lot covered by buildings, while setbacks in the same Table 6100.2 fix separate minimum distances from the front, side and rear property lines; a project must satisfy both limits at the same time.

What happens if I build over the coverage limit without a permit?

Section 59-4350.1 makes the owner, any person maintaining the violation, and anyone who assisted in it each individually guilty of a separate offense, with § 59-4350.2 treating every day of the violation as a new Class "a" offense fined up to $500.00 under § 1-6.
