Zoning, building permits and septic rules in Brownsville, Oregon

Brownsville, Oregon adopts and enforces its own zoning inside city limits1. Building permits are different: the city accepts applications as a drop-off point, but Linn County enforces the building code2. Septic permits come through Linn County Environmental Health3, and the city also requires its written permission4.

Does Brownsville, Oregon have zoning, and what does it mean for lot size and setbacks?

Yes. Brownsville adopts its own zoning inside city limits as Title 15 of the Brownsville Municipal Code1. The city's zones are LDR (low density residential), MDR, HDR, OTC (old town commercial), VC, LI, HI, SD and P10.

The dimensional rules depend on the district. A single-family lot needs at least 7,500 square feet in LDR, 6,500 in MDR and 5,000 in HDR7. In LDR the front yard is at least 20 feet and the rear yard at least 15 feet11. Buildings may cover 30 percent of an LDR lot, with total impervious surface capped at 40 percent12. A principal building in LDR may not exceed 35 feet in height, and an accessory building may not exceed 22 feet13.

The city's staff check setbacks as part of city-specific permits2.

Do you need a building permit in Brownsville, and who issues it?

Oregon requires a building permit to construct, enlarge, alter, repair or move a residential building5. In Brownsville the permit is enforced by Linn County, not the city: the city's own planning page says it is a drop-off point for Linn County building permits, does not inspect or enforce them, and leaves enforcement of the building code to the county2.

The Linn County Planning & Building Department issues the permits and inspections and uses the Oregon ePermitting system14. Permitted work is subject to inspection by the building official, and a new dwelling needs a certificate of occupancy before it is occupied1516.

Owner-builders can use Oregon's exemption from certain structural requirements; a permit is still issued9. We could not confirm Brownsville's own fee schedule or process; ask the city office.

How do septic permits work inside Brownsville?

Where a city sewer is available, the sewer is the answer: owners of buildings within 200 feet of a street or right-of-way with a public sanitary sewer must connect as soon as service becomes available, at their own expense6.

Where no public sewer is available, a private system needs the state-rules permit, the city's written permission and a city inspection fee before construction starts4. Linn County Environmental Health provides septic site approvals, plan reviews, permits and inspections3. The call goes to17.

Across Linn County, USDA rates only about 6 percent of soils as not limited for a conventional drain field18. That is a county figure, so expect a site evaluation and possibly an engineered system on any unsewered lot.

Can you live in an RV or tiny home in Brownsville?

Brownsville permits occupancy of recreational vehicles only in line with its special development standards, and we have not confirmed what those standards allow in residential zones8. The city's VC zone allows RV parks on parcels of three acres or more as a conditional use8.

Oregon law bars local governments from prohibiting an RV solely because it is an RV when it sits in an RV or manufactured-dwelling park with water, power and sewage hookups19. It does not make living in an RV on an ordinary city lot legal.

Manufactured homes on individual lots are a permitted use in the residential zones, subject to the same development standards20. We could not confirm the city's rules for tiny homes; ask the city's planning office.

Building a home in Brownsville: the steps, in order

  1. Confirm the zone and its lot size, setbacks and coverage limits with the city planning office102.
  2. Find out whether a city sewer is within 200 feet; if so, plan to connect6.
  3. If no sewer is available, start septic site approval with Linn County Environmental Health and get the city's written permission4.
  4. Submit the building permit application at city hall or to the county; Linn County reviews plans and issues the permit214.
  5. Call for inspections as work proceeds; work must stay exposed until approved15.
  6. Get the certificate of occupancy before moving in16.

What to check before you buy land in Brownsville

Confirm whether the parcel is inside city limits. Linn County's zoning applies to unincorporated land and city zoning replaces it after annexation21; for land outside the city, see the Linn County page.

Wells are a separate question. Oregon requires a landowner well permit, a $550 fee and a $10,000 bond for a landowner-constructed well22, but we could not confirm how that applies inside the city; ask the city office.

Flood hazard and driveway access inside the city are also unconfirmed. For taxes, Linn County's effective property tax rate is 0.9 percent23 and the median bill is $3,130 a year24.

Watch-outs

  • Electrical permits are handled in Albany rather than at Brownsville city hall, according to the city's planning page2.
  • Residential zoning in Brownsville allows RVs and manufactured homes only under special development standards that we could not confirm, so get the city's answer in writing before buying8.
  • Septic is split: Linn County Environmental Health approves the system, and the city separately requires written permission and charges an inspection fee4.
  • Building permit fees, floodplain rules and accessory dwelling rules inside Brownsville are unconfirmed; ask the city planning office2.
