Salida’s size cap is conditional rather than a single number: 1,000 sq ft (internal/attached ADU, capped at 800 sq ft above the first floor; or detached ADU 16 ft or less in height); 800 sq ft (detached ADU over 16 ft in height) — worth reading closely before sizing a unit.
Short-term rental of the ADU is not permitted, so the model here is long-term tenancy or family use.
Parking: 1 space, but only required if the lot lacks existing off-street parking, the base zoning district requires off-street parking for all dwellings, or on-street parking is prohibited on that block face; otherwise 0.
Property tax runs lighter than most of the state here: 46.08 mills total in the example tax area (Chaffee County tax area 07), about 49% below the median of the Colorado tax areas we track (levies vary by parcel).
And Salida is one of only 30 Colorado jurisdictions certified ADU Supportive, which makes residents eligible for CHFA’s state-backed ADU financing — an interest-rate buydown and credit enhancement offered through participating lenders. Most of the Front Range doesn’t have this lever.
What an ADU adds to the tax bill in Salida, and the federal benchmark for what it rents for.
Levies: Chaffee County Assessor's Office — 2025 Abstract of Assessment and Levies for Chaffee County (Chaffee County Tax Levies for Tax Year 2025, Collectable in Calendar Year 2026), plus Summary of Levies and Revenue page — example: Chaffee County tax area 07; levies differ between tax areas inside Salida; check your parcel with the county assessor. Rates: Colorado DOLA, TY2026 — the 10% reduction on the first $700,000 of value applies to the local-government portion, once per property. Rents: HUD Fair Market Rents, huduser.gov.

Free and specific to you. Want to go further?
Yes. The Salida Code Of Ordinances permits accessory dwelling units (§16-3-30), subject to the size, height, setback and use rules quoted above from the ordinance text. Zoning district, lot size and setbacks still decide what fits on a specific lot — the free property check confirms yours.
Yes. An ADU is a new dwelling unit, so Salida requires a building permit (plus any zoning or site-plan review the code calls for) before construction starts. Olerra's all-in price includes permitting, and factory-built units are inspected to the same building code as a site-built home.
Per the Salida Code Of Ordinances: 1,000 sq ft (internal/attached ADU, capped at 800 sq ft above the first floor; or detached ADU 16 ft or less in height); 800 sq ft (detached ADU over 16 ft in height). Both Olerra Flex Flats — the 490 and the 735 — fit under this rule. The free property check confirms what fits on your lot.
No — the ordinance does not permit short-term rental of an ADU here, so plan on long-term tenancy or family use.
A one-off site build with a general contractor typically runs about $500,000–$650,000 for a ~490 sq ft unit. Olerra's factory-built Flex Flats run $300,000–$365,000 (490) and $420,000–$465,000 (735) all-in — site preparation, foundation, utility connections and permitting included.
Roughly $321 per year for every $100,000 of value the ADU adds, in the example tax area shown above: Colorado's TY2026 school (7.05%) and local-government (6.80%) assessment rates on the latest certified (TY2025) levy, a mixed-year estimate. Levies differ between tax areas, so check your parcel with the county assessor.
