Additions, whole-house remodels, garage conversions, and ADUs all live or die on the person coordinating them. The difference between a good build and a nightmare is usually communication and sequencing, not craftsmanship. Describe the project and CCB-licensed Gresham builders respond with scope, timeline, and price.
Confirm address jurisdiction, verify the Oregon CCB record, and give each bidder the same design and scope. Compare allowances, exclusions, licensed-trade roles, inspections, milestones, changes and closeout—not totals based on different assumptions.
Not hammers — coordination. Permits pulled in the right order, subs scheduled so the electrician is not waiting on the framer, inspections passed the first time, and one person accountable when something goes sideways. On a project with six trades, that management is worth its markup. On a single-trade job it usually is not, and a good GC will tell you so.
Bumping out a bedroom or converting an attached garage into living space is common in Gresham, where lots are generous but 1970s floor plans are tight. Both trigger setback review, foundation work, and envelope upgrades to current energy code. Garage conversions also mean solving where the cars and storage go, which is a design question worth answering before demolition.
A serious bid names the scope, the allowances, the change-order process, the payment schedule tied to milestones, and who supplies what. Vague line items are where disputes start. Ask for proof of liability insurance and workers' comp, and confirm the CCB number is active and matches the business name on the contract.
Bids rarely cover identical scope, so line them up item by item before comparing totals. One may include cabinets at a $12,000 allowance and another at $25,000. One may exclude permits entirely. Normalize the assumptions first, then judge price. The cheapest number is often just the one that left the most out.
Define how concealed damage is protected, photographed and priced. Except for immediate stabilization, permanent extra work should wait for a signed change stating scope, price basis and schedule effect. Unit rates work only for defined measurable unknowns.
Tie payments to observable milestones. Final handoff should include inspection status, approved changes, manuals, warranties, finish records, concealed-work photographs and a completed punch list. The final invoice follows the contracted result, not simply crew departure.
Describe your project once and we help connect your request with relevant local contractors who serve your area. The request is free, there is no obligation to hire, and you decide whether anyone is right for the job.
Structural work, additions, and ADUs go through City of Gresham Development Services for plan review and inspections, while properties outside city limits toward Orient, Damascus, and Corbett permit with Multnomah County. Review timelines vary with workload. A GC who knows the counter and the reviewers keeps a project from stalling for weeks over a correction item.
Gresham parcels are generally deeper and wider than close-in Portland lots, which makes detached ADUs, shop buildings, and single-story additions more feasible than they would be inside the urban core. Setbacks, lot coverage, and tree requirements still govern. Have your builder confirm what your zoning allows before you fall in love with a footprint.
A 1,400 to 1,900 square foot home built between 1972 and 1992, with a compartmentalized floor plan, an original panel, and single-pane or early double-pane windows. These houses respond very well to opening up the main level and upgrading the envelope. Older farmhouses on the east edge are a different project with their own surprises.
| Control | Weak bid | Comparable bid |
|---|---|---|
| Scope | Remodel included | Room-by-room inclusions and exclusions |
| Allowances | Finish allowance | Item, quantity, basis and deadline |
| Schedule | Estimated duration | Review, ordering, inspections and work |
| Changes | Extra as needed | Evidence, price and time approved in writing |
Separate design, permits, demolition, structure, trades, utilities, site work, protection, restoration, finishes, allowances and contractor fee. Use specifications and measured quantities. Unsupported local averages cannot account for the property, design completeness or concealed conditions.
If the job is one trade, hire directly and save the markup. Once three or more trades have to be sequenced around inspections, self-managing usually costs you more in delays than the GC fee would have. Be honest about your availability during weekdays.
Look up the CCB number on the state's contractor search and confirm the status is active, the business name matches, and there is bond and insurance on file. Also check whether complaints have been filed. It takes a few minutes and it is the single highest-value screening step.
Simple over-the-counter items can be quick, while plan review for an addition or ADU often runs several weeks and longer if corrections come back. Build that into your schedule expectations. A contractor who promises immediate permits is not being straight with you.
Something modest tied to mobilization and material ordering, with the rest on milestones. Large advance payments transfer your risk to the contractor's cash flow. If a builder needs most of the money before starting, that is a reason to keep looking.
Many local builders do, and larger lots here make them practical. Utilities, setbacks, parking, and whether you go attached or detached drive both cost and feasibility. Start with a zoning check before design so you are not redrawing plans later.
Name the item, quantity, budget basis, tax, delivery, labor treatment and selection deadline.
Document it and approve scope, price and schedule in writing before permanent repair is concealed.
Inspection status, approved changes, manuals, warranties, finish records and a completed punch list.
