FAQ
I came to real estate after a career in structural engineering, where costs, sequencing, constructability, and risk had to be explained clearly enough for people to act on them. I later wrote about affordable housing for the Portland Business Journal and have continued researching how land, construction, permitting, infrastructure, financing, and time shape the housing market.
Nathan Austin is a licensed Realtor in Oregon and Washington, holds a B.S. in Architectural Engineering, and previously worked as a structural engineer. This article is a cost-analysis framework; every numeric placeholder below must be replaced with a current sourced figure before publication.
Oregon voters adopted Measure 5 in 1990, placing constitutional limits on property taxes for schools and general government. Measure 50 followed in 1997, replacing the prior tax base with an assessed-value system that generally limits annual growth in assessed value while allowing specified exceptions. Together, the measures constrained how quickly local property-tax revenue could respond to rising market values and service costs. [OFFICIAL OREGON SOURCE LINK REQUIRED.]
Those constraints did not remove the cost of reviewing development or expanding infrastructure. They changed the funding environment in which cities provide those services. Portland reorganized its permitting functions and increasingly relied on applicant-paid fees to support plan review, inspections, and related development services. The exact bureau chronology, dates, and current funding split should be inserted here from City budget and organizational records before publication. [CITY SOURCES REQUIRED.]
Taxes and fees are treated differently
Property taxes raise general or dedicated public revenue and are governed by Oregon’s constitutional tax limits. Permit fees and system development charges are structured as charges connected to a service, review, impact, or infrastructure need. Supporters describe that distinction as a lawful way to make development pay for the services and capacity it uses. Critics describe the same structure as an end run around tax limits because required charges can still increase the all-in cost of housing. Whether a specific charge is legally a fee rather than a tax depends on its authorization, purpose, calculation, and use—not simply its label. [LEGAL AND STATUTORY SOURCES REQUIRED; REVIEW BEFORE PUBLICATION.]
This history is included to explain the funding structure, not to assign motive or recommend policy. The final version should cite the Oregon Constitution, Oregon Department of Revenue guidance, Portland budget documents, and the statutes or code provisions authorizing each fee.
I’m tired of watching friends decide that the place they love is not a place where they can afford to have children. I’m tired of seeing clients leave Portland because the combined weight of housing costs and taxes makes another city feel more workable. Those choices may appear as migration statistics, but up close they are grandparents seeing less of their grandchildren, friendships stretched across states, and families giving up the community they spent years building.
Development costs do not stay on a permit invoice. They are financed into a project and eventually show up in mortgage payments, rents, or in homes that never get built. My concern is that households may be paying more over time through those monthly housing costs than they would under a broader general-fund approach. That comparison needs to be calculated with real project data and public-budget figures before it is stated as a conclusion, but it is an important question this article is designed to test.
The cost is larger than a monthly payment.
When families leave, the community loses neighbors, volunteers, customers, workers, future students, and the everyday relationships that make a city durable. Housing affordability is not an abstract production target to me. It determines who gets to remain part of Portland’s future.
Evidence needed for the final article: compare the financed monthly household cost of project fees with plausible general-fund funding scenarios, including who pays, over what period, and with what distributional effects.

System development charges fund the infrastructure new homes connect to: transportation, parks, water, sewer, and other public systems. The case for these charges is that growth should help pay for the capacity it requires rather than shifting the full cost to existing ratepayers. The counterargument is that large up-front charges raise the cost of producing each home and can make marginal projects infeasible. For the reference home, the current combined amount is [DATA REQUIRED FROM CURRENT RATE SCHEDULES].
Portland’s current published permit and plan-review timeline for this project type is [DATA REQUIRED]. Comparable timelines in [NEIGHBORING JURISDICTIONS] are [DATA REQUIRED]. Time becomes a cost through acquisition loans, construction interest, insurance, taxes, consultant remobilization, escalation, and delayed revenue. At a verified monthly carrying cost of [DATA REQUIRED], each additional month adds [CALCULATED AMOUNT] before another board is installed.
New-construction costs create a replacement-cost reference point. When producing an equivalent home becomes more expensive, existing homes can gain value even when they have age or maintenance disadvantages. Buyers comparing new and resale should separate the premium for new systems and lower near-term maintenance from the cost of location, lot, and permitting. Sellers benefit from understanding replacement cost, while owners considering an ADU or addition need to compare total project cost—not just contractor bids—to the income, utility, or resale value created. A detailed ADU cost article will be linked here when published.
1. Read a new-construction price as a stack of land, building, finance, fees, time, and margin—not one construction number.
2. When buying resale, review permit history before assuming an addition or conversion is legal.
3. Legalizing unpermitted work may require design, investigation, selective demolition, upgrades, and fees; use [VERIFIED RANGE REQUIRED] only after scope review.
4. An ADU pencils out only when total cost, financing, rent, utility, and long-term use are modeled together.
5. Treat every early estimate as a range until the site, utilities, zoning, and permit path are known.

How much are permit fees and SDCs on a new home in Portland?
[ANSWER PENDING: insert verified combined figure and official source.]
Why does new construction cost so much in Portland?
The price combines land, site work, construction, design, engineering, financing, permits, infrastructure charges, time, risk, and builder margin. The verified cost stack above will show the relative size of each line.
Do permit fees affect the price of existing homes?
Indirectly. Higher replacement cost can lift the reference price for existing homes, although location, condition, supply, demand, and financing still determine what buyers will pay.
How much does it cost to legalize an unpermitted addition in Portland?
[VERIFIED RANGE REQUIRED.] The final cost depends on scope, documentation, access for inspection, code upgrades, structural work, and whether selective demolition is required.
