The home

Ranch on a 7,500 sq ft lot with a permitted studio

A 1971 ranch, largely original inside, on a level 7,500 sq ft lot with mature planting and a 320 sq ft studio built under permit in 2021. The studio has heat, power and a three-quarter bath but no kitchen, so it is an accessory structure rather than a rentable ADU under current Boulder code — worth understanding before you count on the income.

Represented by Ines Kovač. All measurements are approximate and taken from the assessor record; a buyer should verify square footage, lot dimensions and permit history independently during the inspection period.

Neighborhood

North Boulder

NoBo runs along Broadway north of Alpine, and is the part of Boulder where the most new construction has happened in the last decade — mostly attached townhomes and small condominium buildings on former commercial parcels.

Housing stock
Contemporary townhomes and condominiums from 2012 onward, alongside a remaining stock of 1950s–70s ranches on the side streets.
Transit
RTD bus 205 and the Broadway corridor; direct bike access on the Fourmile Canyon Creek path.
Parks and open space
Foothills Community Park, Wonderland Lake and the Diagonal Highway open space corridor.

Under the Fair Housing Act we describe the place and its built form only — never the people who live there, and never who a home would “suit”.

An estimate only. Conventional 30-year assumptions, hazard insurance modelled at 0.35% of value a year, and mortgage insurance added below 20% down. Your actual payment depends on credit, debt ratios, reserves, occupancy and the loan product. A pre-qualification is a lender's opinion based on what you tell them; a pre-approval is based on documents they have verified. Sellers here take the second one seriously and largely ignore the first.
