Cottage Grove, Oregon Building Permit Guide

The City of Cottage Grove permits its own construction: the Building division of Community Development reviews plans and issues and inspects building, electrical, mechanical and plumbing permits. Contractors, designers and homeowners can all file in Oregon ePermitting, which the City uses as a full-service system from application to certificate of occupancy. Structural fees start at $88 and plan review adds 65%, under the fee schedule the City updated on November 1, 2024.

Community Development is at 400 E. Main Street (541-942-3340), and Melany Klemmer, the Community Development Manager, is listed by the state as the Building Official. Since January 16, 2025 the department closes to walk-ins on Thursdays from noon to 5 p.m. and sees people by appointment only then. Cottage Grove, in Lane County, had 10,851 residents in the Census estimate for 2025.

The City permits work inside its city limits. Outside them, including land inside the urban growth boundary, Lane County Land Management issues the permits.

What requires a building permit in Cottage Grove?

The City publishes a project-by-project list, “Common Development Work and Type of Permit”, that says whether a job goes to Building, Planning, Engineering or no one. Many small exterior jobs need only a Planning review, and the state’s 2026 residential code chapter 1, mandatory since October 1, 2026, sets the building-permit thresholds behind it.

What Cottage Grove decides and what the state holds

The building code, including which projects are exempt, is the state’s, and the City sends visitors to BCD’s site for codes and to the state’s Design Criteria Hub for local snow, wind and seismic values. Cottage Grove sets its fees by resolution, runs its own zoning, historic preservation and Willamette Greenway rules through Planning, and administers the National Flood Insurance Program through its Emergency Management division.

Oregon’s building code and its exemptions are the same in Cottage Grove as everywhere in the state, and an exemption from the building permit is not an exemption from zoning, land use or a trade permit. Site snow, wind and seismic values come from the state’s Oregon Design Criteria Hub. How Oregon’s statewide code works

Cottage Grove building department: who handles permitting

Community Development has four divisions. Building issues permits, reviews plans and inspects under the state specialty, fire and electrical codes. Planning handles land use, historic preservation, the Main Street program, floodplain enhancement and code enforcement. Economic Development runs the Enterprise Zone and business recruitment, and Emergency Management keeps the flood insurance program and hazard plans. Septic permits on lots without sewer come from Lane County Land Management, DEQ’s onsite agent for the county, and asbestos removal goes to the Lane Regional Air Protection Authority.

Permit types

Residential permits

Cottage Grove publishes a building permit application, separate electrical, mechanical and plumbing applications, a combined application for a new single-family home, a manufactured home placement application with a supplemental information sheet, deferred submittal and additional plans forms, and a Homeowner Acknowledgement Form for owners doing their own work. A new house is filed with two complete sets of plans, two sets of specifications and structural calculations, a reproducible site plan on letter or tabloid paper, the residential plan intake checklist, the energy measure selection form and the exterior wall drainage form, or the same documents uploaded in ePermitting.

Commercial permits

Commercial work follows the City’s commercial plan review submittal checklist. New buildings, mixed-use buildings or new residential space inside an existing building, additions, moved or new walls, changes of use and seismic upgrades need both Building and Planning; commercial siding and the demolition of a historic building start with Planning. Fire alarms, sprinklers and paint booths are priced on the structural table, with fire and life safety review at 45% of the structural fee, and essential facilities pay a 1% seismic surcharge on plan review.

For tenant improvements and new commercial builds, Alliance handles commercial permit expediting through issuance. More on this: commercial building permits explained.

What comes before the building permit

Many items on the City’s list need both Building and Planning sign-off, and Planning also handles street trees with the urban forestry program. Grading and clearing need an erosion control permit; new or wider driveways need Engineering and Planning approval for the right-of-way; sewer connections in the street go to Engineering; and a new water connection or meter involves Utilities, Engineering and a plumbing permit. Decommissioning an oil tank starts with a call to Public Works and Development. FEMA’s status book shows Cottage Grove’s effective flood map dated June 2, 1999, and the city in the Community Rating System at Class 6, which gives NFIP policies there a 20% discount.

Cottage Grove permit costs and fees

The building fee schedule posted with the forms is section XII of the City’s fee code, updated November 1, 2024 after Resolution 2154 of October 14, 2024. Structural valuation follows the ICC Building Valuation table in force on April 1 each year. The schedule names the state surcharge only line by line: demolition and permit extensions are “not subject to State Surcharge”, and reinstating an expired permit is “subject to State Surcharge”. A technology fee applies to every specialty code permit and to planning and engineering applications; the 2024 schedule lists it as unchanged without printing the rate.

Worked example. A house valued at $300,000 falls in the $100,001 to $500,000 band: $990.25 plus 200 × $5.45 ($1,090) gives a structural permit fee of $2,080.25, and plan review at 65% adds $1,352.16, for $3,432.41. The plumbing, electrical and mechanical permits, the technology fee and the state surcharge are added to that.

Other charges in the schedule: deferred submittals at 65% of the fee for the deferred part ($110 minimum), phased projects at $220 plus 10% of the total building permit fee (no more than $1,500 a phase), a foundation-only permit priced on 20% of the project value, complete demolition at $55, manufactured home placement at $330 plus the $30 state fee, and stand-alone home fire sprinklers from $150 for up to 2,000 sq ft to $327 above 7,200 sq ft. Work begun before a permit pays an investigation fee at actual cost.

Trade permits and who may pull them

Cottage Grove issues its own electrical permits, so the same office handles all four trades. The City’s list sends a service panel change, a new outlet or switch, a replaced furnace, an air conditioner, heat pump or mini-split, a new bathroom, replaced fixtures, water and sewer lines and irrigation systems to Building. Electrical master permits for ongoing work cost $110 a year plus $88 an hour of inspection, and the electrical minimum is $68.

How to apply for a Cottage Grove building permit

Review, corrections and what causes delay

A complete residential set is generally reviewed within two weeks, and the City notes that incomplete submittals may be rejected and sent back. Its operating plan, revised in December 2021, commits to telling applicants within three working days whether an application is complete, to reviewing simple one- and two-family plans in ten working days and complex ones in fifteen, and to flagging deficiencies in new commercial buildings and major additions within about three weeks on average. Residential plumbing, mechanical and manufactured home placement permits that need no plan review can often be bought over the counter or are issued within 48 hours. An application is treated as abandoned 180 days after filing unless it is being pursued in good faith or the permit has been issued, and the Building Official can grant extensions of up to 180 days each on a written request that shows good cause. Changes after approval are reviewed at $88 an hour, with a half-hour minimum.

Inspections in Cottage Grove

Inspections can be scheduled in Oregon ePermitting, through the state’s inspection line at 1-888-299-2821 or the ORinspect app, using the numbered inspection codes on the City’s code sheet; the City’s operating plan also lists an inspection request line, 541-942-9758. Because the City inspects electrical work as well as structural, mechanical and plumbing work, one team covers every trade on a Cottage Grove job, and the certificate of occupancy is issued through ePermitting at the end. The plan says the City’s own certified inspectors do the work and that Lane County and a private firm are under contract when the workload exceeds capacity.

A re-inspection or an inspection beyond the number allowed costs $88, an inspection with no listed fee is $88 an hour, and an inspection outside business hours is $132 an hour with a two-hour minimum. A temporary certificate of occupancy for 30 days needs the Building Official’s approval and costs $100 for a home.
