The County does not run its own building counter. Its published answer to how to get a building permit in the county is that "the county contracts with the City of Waterloo for this service. To obtain a building permit information call Building Inspection at 319-291-4319." Planning and zoning for the county is also transacted at Waterloo City Hall, 715 East Mulberry Street. Read that division carefully rather than collapsing it: the contract moves administration, and the county Code section 15.05.010 separately and expressly moves code content by adopting the Waterloo ordinances on a continuing basis, but Black Hawk County remains the adopting authority for the unincorporated area and its own chapter carries exceptions that Waterloo ordinances do not - most importantly the 35-acre agricultural exemption described in the permit entry.

THIS COUNTY IS THE UNUSUAL CASE WHERE THE ADOPTION IS EXPRESSLY FLOATING RATHER THAN FROZEN, AND THAT CHANGES THE ANSWER. Black Hawk County Code section 15.05.010 adopts, as the Uniform Building Code of the County, "the 2009 International Building Code (IBC) and the 2009 International Residential Code (IRC) as they are adopted and amended by the City of Waterloo in Ordinance Nos. 4995, Plumbing Regulations, and 4996, Building Code, adopted on the twenty-first day of June 2010, and Ordinance No. 5096, Electrical Regulations, adopted on the twenty-seventh day of February 2012." Standing alone that recital would fix the county on the 2009 editions. It does not stand alone. The same section closes: "the adoption of the Waterloo ordinances shall be continuing, so that any adoption, amendment or change in the Waterloo ordinances shall constitute such a change in the Black Hawk County ordinance" (amended during the 2014 recodification; Ordinance 117, section 1, 2013). Waterloo has since adopted the 2021 International Residential Code by its Ordinance No. 5629 of December 20, 2021, and on the continuing-adoption clause that adoption carries the county with it. So the operative residential code in the unincorporated county is the one Waterloo currently enforces, while the county own codified text still recites the 2009 editions. BOTH READINGS ARE SET OUT HERE RATHER THAN ONE BEING CHOSEN, and the practical advice follows from that: confirm the edition with the building inspection office before relying on a provision that changed between the 2009 and 2021 editions. See the Waterloo, Iowa record for what that city currently enforces and for its local amendments.

Black Hawk County publishes no dollar or square-footage threshold of its own, and takes its fee structure from Waterloo: County Code section 15.05.030 provides that "the building permit fees as adopted or amended by the City of Waterloo, Iowa, and on file with the Black Hawk County Board of Supervisors are hereby incorporated by reference and the fee structure set out in the model ordinance is stricken, as it is not applicable to Black Hawk County." THE EXEMPTION THAT MATTERS MOST ON RURAL WORK IS AT SECTION 15.05.020 AND IT IS NOT A THRESHOLD BUT AN OWNERSHIP TEST: "this chapter does not apply to any person who owns more than 35 acres of land designated for agricultural use." A roofer working a farm building for an owner above that acreage is therefore outside the county building code chapter altogether, and the question turns on the owner holding and the land designation rather than on the building or the job. Establish it before quoting, because it decides whether a permit exists at all. The same section omits the electrical, gas, mechanical and plumbing inspection portions of the adopted codes except as covered by the Waterloo ordinances, and lowers the sprinkler requirement threshold to 9,000 square feet regardless of building use.

THE LAYER ANSWER HERE DEPENDS ON WHICH EDITION GOVERNS, AND THE TWO CANDIDATES GIVE DIFFERENT RULES, SO BOTH ARE SET OUT AND NEITHER IS ASSERTED. See the adopted code entry for why the county sits between two editions: its own text recites the 2009 codes while its continuing-adoption clause carries it to whatever the City of Waterloo currently enforces, which is the 2021 edition. On the 2021 reading the rule is a straightforward two layers maximum. Section R908.3.1.1 bars a roof recover where any of three conditions occur, the third being "where the existing roof has two or more applications of any type of roof covering," so one existing layer may be recovered and a second forces removal. On the 2009 reading the rule is not a layer count at all. Section R907.3 of that edition carries a FOURTH condition absent from the later text: "for asphalt shingles, when the building is located in an area subject to moderate or severe hail exposure according to Figure R903.5." That condition can require a full tear-off over a single existing layer, so no layer number states the rule under the 2009 edition. The practical consequence for a roofer is that an overlay which is plainly permitted under one reading may be barred under the other, and the difference falls on exactly the common case of asphalt shingles. Settle the edition with the building inspection office before quoting an overlay in the unincorporated county.

7% in unincorporated Black Hawk County - the 6% Iowa state sales tax plus a 1% local option sales tax, per the Iowa Department of Revenue local option sales tax tables effective July 1, 2026. HOW IOWA TAXES A ROOF IS UNUSUAL, AND IT CUTS BOTH WAYS. Iowa Code section 423.2(6) makes a list of enumerated services taxable at the state rate, and paragraph (l) of that list reads, in its entirety, "Roof, shingle, and glass repair." Against that, section 423.3(37) exempts "the sales price of services on or connected with new construction, reconstruction, alteration, expansion, remodeling." The materials side flips with the labour side. Under section 423.2(1)(b)(1), materials sold to a contractor "for the erection of buildings and other structures or for the reconstruction, alteration, expansion, or remodeling of buildings and other structures are retail sales of tangible personal property," on which the contractor pays the tax as consumer, while materials sold "for use in repairs to or for installation in existing buildings and other structures are purchases for resale." So a job characterised as a repair carries taxable labour and resale-purchased materials, and a job characterised as reconstruction or remodeling carries exempt labour and taxed materials. Which branch a particular tear-off and replacement falls into is a fact-specific question the statute does not answer, and it changes who owes the tax rather than only how much, so settle it with an accountant rather than assume it. The Department of Revenue tables record the Black Hawk County unincorporated area as having the local option tax in effect since October 1, 1991, with no sunset date. Waterloo and Cedar Falls each carry the same 1% rate in their own rows, so crossing into or out of city limits within this county does not change the sales tax rate.
