Rogue ADU planning tool
Explore rough project cost, loan need, qualification limits, rent, and monthly cash flow using editable Ashland assumptions.
This is an early planning estimate—not a lender prequalification, appraisal, contractor bid, or promise of rent.

Answer a few planning questions to choose a project type and identify financing conversations worth having.
This checks the address against public City, county, and Oregon GIS sources for zoning, parcel area, mapped building footprint, water-resource constraints, and the 2024 Buildable Lands Inventory. The calculator does not store the address.
Enter an Ashland street addressYou’ll receive an automated preliminary property screen.
These are screening results, not final eligibility determinations. Every address on the supplied spreadsheet is treated as being within the CEJST area funded for the ADU Infill Pilot by an EPA Thriving Communities Grant. BLI status still does not decide whether an ADU is allowed, and the proposed Opportunity Zone has not yet received final federal designation.

Replace defaults with contractor and City estimates when available.
City utility rebates
Select only incentives the City or an installer has confirmed for this project. The calculator subtracts the selected amount from the financing need.
Potential maximums are shown before project-cost caps. Ashland requires an electric utility account, qualifying equipment, applicable permits, and program approval. Confirm whether the City and Oregon heat-pump incentives can both be applied without exceeding installed cost.
Use a long-term payment—not an interest-only construction payment.
This uses three common constraints: debt-to-income, combined loan-to-value, and loan-to-cost. Lenders calculate each differently.

How to use the result
Confirm site feasibility. Review setbacks, utilities, access, wildfire conditions, historic-district considerations, and the selected plan with the City.
Replace generic costs. Obtain a site-specific contractor budget with allowances, exclusions, draw schedule, and at least a 10% contingency.
Verify value and rent. Ask a lender whether it uses as-completed value and what share of appraiser-supported future ADU rent it can count.
Compare permanent payments. Consider construction-to-permanent financing, home equity, and any grant, reserve, rate-bydown, or soft-second support.
Factory-built and accessibility pathways
Factory-produced housing funds largely operate through manufacturers and affordable-housing developers. Accessibility programs generally serve an eligible resident in an existing occupied home.
Pacific Wall Systems advertises locally produced Dogwood, Beech, Magnolia, and Cascara component kits from $18,000 to $28,000. The calculator applies an editable 7% saving to the comparable site-built construction baseline, then shows the kit within the reduced installed budget.
Oregon’s current program can serve new residential construction through an approved contractor. Contractor confirmation should precede entry in the financing calculation.
OPI-M and OHP may cover resident-specific modifications after an assessment. Healthy Homes and OHCS Restore Health and Safety fund eligible organizations rather than homeowners directly. RVCOG/ADRC is the best local intake for seniors and adults with physical disabilities; Jackson County and VA repair programs have separate geography and eligibility rules.
LIFT factory-produced housing, the Older Adult Housing Program, and Elderly and Disabled bond financing are structured for qualifying affordable developments. They remain partnership opportunities for a nonprofit-sponsored portfolio.
Financing conversations
Public product descriptions are starting points. Confirm ADU eligibility, as-completed value, projected-rent treatment, owner occupancy, contractor requirements, and draw administration directly with each lender.
Columbia Bank expressly advertises ADU-eligible construction and renovation financing. Rogue Credit Union advertises construction-to-permanent and portfolio options including two homes on one lot. First Community, Banner, First Interstate, and Evergreen offer related products whose ADU rules need confirmation.
Potentially useful for a conversion or defined construction budget, especially when preserving a low-rate first mortgage matters. Rogue, First Community, Banner, KeyBank, U.S. Bank, and Peak advertise equity-based products; availability and limits vary.
Some banks offer smaller unsecured home-improvement or personal loans. These avoid a lien but generally carry shorter terms and higher payments, making them a poor fit for a large detached build.
Standard products may not count enough future rent or completed value. A locally supported pilot could combine feasibility help, a reserve, subordinate capital, or an affordability/accessibility commitment; no such Ashland-wide product should be assumed until launched.
Calculator FAQ
Yes, when you select a confirmed rebate. The calculator now subtracts selected City of Ashland energy incentives from the financing need, alongside the separate Oregon heat-pump incentive. It models Ashland’s current space heat-pump, heat-pump water-heater, electric-ready panel and circuit, induction-cooking, and City-confirmed weatherization rebates.
The income-qualified control doubles eligible space-heating and water-heating rebates. For a rental, Ashland says the renter’s income determines qualification. Panel assistance may rise from $1,000 and 50% of cost to as much as $2,000 and 100% of cost; the circuit rebate remains capped at $600. All values remain subject to the actual project cost and City approval.
Eligibility matters. Ashland’s space heat-pump rebate currently requires replacement of the home’s main heating system, and weatherization incentives apply to existing electrically heated homes after a City energy review. They should not be assumed for a new detached ADU. The $150 induction incentive explicitly includes new residential construction. The City’s heat-pump water-heater description refers to replacing an existing unit.
Ashland’s free pre-approved plans, estimated size-based SDC reduction, and all-electric impact-fee treatment remain planning items rather than automatic deductions. PacWall pricing starts with an editable 7% reduction from the comparable site-built construction baseline.
Defaults use the City of Ashland’s approximately $150-per-square-foot conversion guidance and $250–$500 new-construction range; current Ashland long-term rental listings; a 20% operating allowance; and a 7.50% illustrative permanent rate. The qualification screen applies user-editable DTI, CLTV, LTC, and projected-rent assumptions.
The 2026 HOME options use gross monthly rent limits of $858/$1,055 for a studio, $920/$1,176 for one bedroom, and $1,103/$1,413 for two bedrooms at the 60%/80% selections. Gross HOME rent includes tenant-paid utilities. Planning electricity estimates are $85 for Dogwood and Myrtle, $95 for Barn, $100 for Joel, $105 for Magnolia and Beech, and $125 for Sherrell. They assume efficient all-electric construction with heat-pump space conditioning and include the electric account charge, heating, cooling, water heating, cooking, lighting, and ordinary appliances. They exclude water, sewer, trash, and internet. The City-approved utility allowance—not this planning estimate—controls a recorded affordability agreement.
The Housing Choice Voucher option uses HAJC’s payment standards effective December 1, 2025 for ZIP codes 97520 and 97540: $1,150 for a studio, $1,340 for one bedroom, and $1,670 for two bedrooms. The calculator subtracts the same planning electricity estimate to show a possible contract-rent target. Payment standards are not promised rent or a general rent ceiling. HAJC must approve the rent as reasonable, apply its official utility allowance, verify the tenant’s voucher and authorized bedroom size, and inspect the unit. The tenant generally contributes an income-based share and HAJC pays the approved subsidy directly to the owner.
The proposed Ashland OZ result follows the August 2026 Ashland working list supplied for this calculator; the proposal has not received final designation. All addresses in the supplied Buildable Lands spreadsheet are classified here as being within the CEJST area funded for the ADU Infill Pilot Project through an EPA Thriving Communities Grant. Actual eligibility, interest rate, fees, value, taxes, insurance, construction cost, available incentives, and rent will vary. The result does not determine legal feasibility, creditworthiness, affordability, or investment suitability. Do not enter Social Security numbers, account numbers, or other sensitive information; this calculator does not need them.
