Rebuilding & ADUs

Rebuild, add a home or build new

Plain-language guides for rebuilding after the 2020 fire, adding an accessory dwelling unit or small home, and lining up permits, septic, utilities and money. Start with the step you’re on.

Start here

Start with your situation

Every project on the river runs into the same three questions: what the rules allow, what the land can hold and how to pay for it.

Rebuilding after the 2020 fire?

Some temporary rebuilding rules have ended and some still apply. Know which ones before you design.

Check the rules

Adding a second home or ADU?

Accessory dwellings, tiny homes and manufactured homes each come with their own rules and hidden costs.

Buying land to build on?

On most rural lots the septic system decides what can be built. Ask that question before you buy.

Start with septic

Step by step

Six steps from idea to move-in

The order matters: each step can change the one after it. Lane County issues the permits; these guides help you get ready for that conversation.

  1. 1

    Check which rules apply

    Rebuilding rules, nonconforming uses and zoning decide what can go back on a lot and how big.

  2. 2

    Know the site

    Septic, soils, landslide and flood risk can limit where and what you build.

  3. 3

    Look up the permit history

    See what has already been permitted on the property before you plan.

  4. 4

    Get permits and waivers

    Apply through Lane County and avoid the inspection problems that slow projects down.

  5. 5

    Line up power and water

    Underground service lines and river-friendly landscaping programs can lower costs.

  6. 6

    Pay for it

    Weigh insurance, loans and grants before you commit, and use local rebuilding help.

Homes & housing options

More ways to add a home

Small homes and second units can add places to live without new subdivisions. Each has trade-offs worth knowing first.

Good to know

Check before you build

Rules and programs change. Several rebuilding programs from the first years after the 2020 fire have closed or changed, so confirm current details with Lane County before you design, buy or apply.

If something here is out of date, tell us and we’ll fix it.

Questions

FAQ

Does MCP issue permits or approve plans?

No. Lane County issues building, land use and septic permits. MCP explains the process and points you to the official sources.

Where should I start with an ADU or small home?

Start with what your zone allows and whether your septic system can handle another home. Then see the tiny homes and ADU guides.

I’m rebuilding in downtown Blue River. Is there anything different?

Yes. Downtown Blue River has its own zoning and wastewater questions. See Blue River Recovery and Community Building.
