Summary

Harford County adopted the 2021 International Building Code by reference under § 82-1, making its permit-and-inspection provisions county law, enforced by the Department of Inspections, Licenses and Permits. Fees run from a flat $160 for simple work to $0.15 per square foot on new construction.

These county ordinances apply to unincorporated areas of Harford County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

The 2021 International Building Code (hereinafter referred to as the Building Code, or code) published by the International Code Council, Inc., is hereby adopted and by reference thereto is made a part of this chapter with the same force and effect as though set out in full herein, save and except such changes, amendments, revisions, deletions, subsections and/or additions as are specified in this chapter. If conflicts with this code, or with changes, amendments, revisions, deletions, subsections, and/or additions to that code are found elsewhere in the County Code, the most restrictive provisions shall govern.

Full Breakdown

Section 82-1 adopts the 2021 International Building Code, published by the International Code Council, as part of Chapter 82 with the same force and effect as if printed in full in the county code, and directs that where the adopted code conflicts with another part of the county code, the most restrictive provision governs. A copy must be kept on file for public inspection in the office of the Director of Administration and the office of the Council Administrator. Section 82-2 renames terms for local use: 'building official' means the Director of the Department of Inspections, Licenses and Permits, and 'Department of Building Safety' means that same department, which is the office that issues permits and inspects work under the adopted code.

15 per square foot plus $200 for commercial work, with a 50% fee multiplier for certain fire-resistive construction types and 25% for assembly, institutional and residential occupancy groups. Simple permits carry flat fees: $160 for a pellet or wood stove, sump pump, basement gutter drain or foundation repair, and $20 for a 1- or 2-family accessory structure under 200 square feet, which needs no certificate of occupancy or inspection. A demolition permit runs $175 residential or $275 commercial, waived for training exercises by a county volunteer fire company.

Working without a permit or under a stop-work order adds a penalty on top of the regular fee: $500 for a first occurrence, $750 for a second, and $1,000 for a third or later occurrence with an administrative hearing. If a permit is disapproved or withdrawn before issuance, § 157-3(E) refunds 50% of the fee paid.

Violations & Fines

A written notice of violation for working without a valid permit or license, or a stop-work order, carries an added penalty on top of the base fee: $500 for a first occurrence, $750 for a second, and $1,000 for a third or later occurrence, with the county holding an administrative hearing at that point. Proceeding without a required prior inspection draws a separate $50 penalty.

Frequently Asked Questions

What building code applies in unincorporated Harford County?
The 2021 International Building Code, adopted by reference under § 82-1 of the county code. It applies with the same force as if printed in full, and where it conflicts with another part of the county code, the more restrictive rule controls.
How much does a residential building permit cost?
Section 157-16 charges $0.15 per square foot for residential new construction, additions or alterations, plus a $100 nonrefundable application fee. Permits without a measurable square footage, like a pellet stove or sump pump, carry a flat $160 fee instead.
Do I need a permit for a small shed?
A 1- or 2-family accessory structure under 200 square feet needs only a $20 permit with no certificate of occupancy or inspection required, under the accessory-structure line of the § 157-16 fee table. At 200 square feet or more, the standard $0.15-per-square-foot fee plus a $100 application fee applies.
What happens if I build without a permit?
Beyond the regular permit fee, § 157-16 imposes a written-violation penalty of $500 for a first occurrence of working without a valid permit, rising to $750 for a second and $1,000 for a third or later occurrence, which also triggers an administrative hearing.
