Basement Apartment Layouts for Pueblo Rentals
Census figures put owner-occupied homes at 63.8% of Pueblo's occupied housing, so roughly a third are rentals. A basement unit adds one more without building on the lot. Most conversions fall into one of three layouts, and the layout decides how much of the cost goes into doors, walls and fire separation rather than finishes.
Basement Apartment With Its Own Outside Entrance
A one-bedroom unit with a private door is what most landlords picture. The entrance is often the biggest single structural item, because it means cutting the foundation and building an exterior stairwell, or reusing a walkout door if the lot slopes.
- Cost guide range: $50-100 per sq ft (HomeGuide)
- Rooms: bedroom with an egress window, full bath, kitchen, living area
- Exit: the outside door can serve the unit, but a bedroom still needs its own egress window
Basement Studio Apartment
A studio keeps the walls to a minimum: one open room for living and sleeping, a bathroom with a door and a kitchen along one wall. Fewer partitions mean less framing and drywall, and the egress opening serves the single sleeping area.
- Cost guide range: about $30,000-60,000 for a 600 sq ft basement unit (HomeGuide)
- Saving: HomeGuide says a basement that is already finished and only needs a kitchen and bathroom costs less
- Kitchen: a full range or a smaller basement kitchen setup with its own circuits
Basement Apartment in a Two-Family Split
When the house is treated as a two-family dwelling, the code asks more of the floor between the units. The 2021 IRC requires a 1-hour fire-resistance-rated wall and floor assembly between two dwelling units, or half an hour if the building has a full sprinkler system. In a basement unit, that assembly is the ceiling under the upstairs floor.
- Separation: 1-hour rating (1/2 hour with sprinklers), per 2021 IRC R302.3
- Circuits: each unit's branch circuits serve only that unit
- Cost guide range: toward the top of HomeAdvisor's $40,000-125,000, since the rated ceiling and separate utilities add work
- Ask SoCoBD early whether your layout is reviewed as an ADU or as a two-family dwelling

Basement Apartment Rules in Pueblo
The building work is only half of a rental conversion. These are the local checks to settle before a design is drawn.
Contractor on the permit
SoCoBD issues homeowner permits only to an owner who lives in the house as a primary residence. A unit built for rent needs a contractor. How permits, fees and inspections run is covered on the basement renovation page.State ADU law
Colorado's HB24-1152 lists Pueblo among its subject jurisdictions. That means one ADU, including one inside the house, has to be allowed where a single-unit detached home is allowed, through an administrative review with no public hearing. The city can still require its fire, building, utility and stormwater codes.Local zoning
HomeGuide's advice holds here: check zoning before you pay for plans. Ask the City of Pueblo planning office how its current code applies the state law to your lot.Dwelling unit test
A kitchen with a cooking appliance, a bedroom and a full bath together make a dwelling unit under the 2021 IRC. That brings in the separate-circuit rule, and it can bring in the two-family separation above.Sleeping rooms and alarms
Each new bedroom needs an egress opening, and a permitted alteration brings smoke and CO alarms up to new-home locations (alarm rules).Family use instead
If the space is for a parent or adult child rather than a tenant, the basement in-law suite page covers that version.
Tell us the basement's square footage, whether there is an outside door and whether a bathroom rough-in exists, and we pass the details on. Ask for the scope in writing, with the entrance, the kitchen, the bathroom and any fire separation priced on separate lines.
