Waterloo building department

Waterloo’s Building Inspection Department, at City Hall (715 Mulberry Street), issues building, electrical, plumbing, HVAC, sign, demolition, and fire-protection permits inside Waterloo. Unusually, the same department also issues building, electrical, and demolition permits for unincorporated Black Hawk County; the online portal has a separate “BHC” set of permit types for county addresses.

What needs a permit

The department’s homeowner handout says permits are required for everything except flooring, painting, and countertops. That includes fences over 4 feet tall, roofing, decks, siding, window and entry-door replacement, additions, and remodels. A deck needs a permit regardless of size, height, or whether it is attached or freestanding. Electrical, plumbing, and heating, cooling, or ventilation work each need a separate permit on top of the building permit, including new wiring, new light fixtures, vents, and new or replacement sinks, toilets, tubs, or showers.

Applying through the OpenGov portal

Waterloo takes permit applications online through its OpenGov portal (waterlooia.portal.opengov.com). Under the Building Department category, choose City of Waterloo Residential, City of Waterloo Commercial, BHC (unincorporated Black Hawk County), or Architect/Engineer Plan Review. The last is for design professionals who need plans reviewed before a general contractor is chosen. Contractor registration is approved before you can apply, and permits are reviewed before payment and issuance. No work may begin until the permit is issued. Questions: (319) 291-4319.

What to upload, by permit type:

Permit type	Upload with application
Residential new dwelling	Site plan, building plans, and a Construction Site Runoff (CSR) application (CSR not required for county permits)
Addition, accessory building, deck	Site plan and building plans
Fence	Site plan
Remodel	Floor plan sketch if walls are demolished, built, or finished
Commercial remodel or repair	Building plans

Site plans must show property dimensions, the size of the structure, and distances to lot lines. New-home checklists also ask for driveway, sidewalk, and curb-cut locations, a window schedule (safety glazing and egress), insulation R-values, and a new address assigned by the Engineering Department. Setbacks are set by Planning & Zoning, (319) 291-4366. Driveway, sidewalk, right-of-way excavation, and dumpster-in-right-of-way permits are handled by Engineering, (319) 291-4312.

The older Tyler eSuite site (esuite.cityofwaterlooiowa.com) still provides a public permit search by permit number or address and contractor log-in for residential roofing and siding permits and rental registrations.

Contractor registration

General, residential, electrical, HVAC, plumbing, pipe-layer, and sign contractors must register in the OpenGov portal before applying, and permits will not be approved without that registration. General contractors and residential roofers, remodelers, and builders also renew a license each year with INRCOG, giving it a current state contractor registration, a certificate of liability insurance, and fees. Right-of-way contractors need a right-of-way construction bond approved by the City Council.

Homeowner permits

Homeowners can pull permits and do all the work on their primary residence, including electrical, plumbing, and HVAC. Owners of property that is not their primary residence can only pull building permits for it. For trade permits, the property must be residential, and the applicant must own it, live in it, and do the work. Homeowners may not pull permits for a contractor; any contractor hired pulls their own permit. A homeowner hiring multiple trades can act as general contractor on the building permit while each trade contractor pulls its own permit. An owner acting as general contractor on a new house must name a licensed framer. Commercial property owners doing their own minor repairs or remodels register with INRCOG in a “General Contractor Property Owner” category, and electrical, plumbing, and HVAC permits on commercial jobs must be pulled by licensed contractors.

Permits are valid for six months. The inspection card must be posted at the job site before work starts. The homeowner handout lists the residential permit writer/plans examiner as in the office weekdays 7:30 a.m. to 4:30 p.m.

Inspections

Your inspection card lists the required inspections. Most remodels use a combination inspection: only the building permit holder calls to schedule, and one inspector checks all trades in one visit. Typical stages are footing (before concrete is poured), foundation (before backfill), framing and rough-in (before covering), and final. Waterloo does not require a drywall inspection.

Inspectors take requests by phone at (319) 291-4319 from 7:30 to 8:30 a.m., Monday through Friday. A call during that window can sometimes get a same-day inspection; the handout recommends calling at least a day ahead. Voicemail is checked throughout the day. Failed items need correction and a reinspection before anything is covered.

Adopted codes

Waterloo has adopted the 2021 International Building, Residential, Fire, and Existing Building Codes, the 2024 International Mechanical Code, the 2024 Uniform Plumbing Code, and the 2023 National Electrical Code. Local amendments are in the City Code of Ordinances.

Construction notes from city handouts

• Decks: footings for attached decks must reach at least 42 inches below grade. Decks or landings more than 30 inches above grade need a guardrail, and stairs with four or more risers need a handrail. Exterior doors need a landing at least 36 inches deep. Attached decks need hold-down tension devices (at least two, within 24 inches of each end, each rated at 1,500 lb or more).
• Reroofing: one overlay of asphalt shingles is allowed over an original shingled roof; otherwise tear off. Asphalt shingles are not allowed below a 2/12 pitch.

Fees

The building permit fee schedule the city currently links (dated April 17, 2012) is based on valuation. It runs from $24.00 for work valued up to $500, to $181.00 at $10,000, $644.00 at $50,000, and $994.00 at $100,000. Above that, add $5.60 per $1,000 up to $500,000. Commercial projects that need plan review pay a plan review fee of 65% of the building permit fee. New commercial buildings with restrooms pay an extra $45.00 State Handicap Review fee. Reinspections are $50.00 per trip. Work started without a permit is charged double the permit fee or the fee plus $50.00, whichever is greater.
