What the owner needed.
A guided flip for an investor: take a 1970 single-story home that already had an attached two-bedroom, one-bath unit with its own kitchen, renovate the house and the unit to the same standard, and sell it on the MLS as a five-bedroom, three-bath property with a self-contained casita.
- Renovated the existing attached casita: 2 bedrooms, 1 bath and a full kitchen, finished to match the main house
- Finished the home as 5 bedrooms / 3 baths
- Two new A/C systems with separate controls, so the casita is conditioned independently
- New windows, cabinets and quartz countertops in both kitchens
- 48 recessed lights and smart ceiling fans throughout
- Double French doors, new interior and exterior doors
- Updated plumbing with a tankless water heater
- New luxury vinyl flooring, interior paint and updated bathrooms
The unit already existed when we took the job; our team renovated it. The home already had the attached 2 bed / 1 bath unit with a kitchen; the team renovated it.
The project's own plan is not published. This is the concept layout for a attached living space of similar use, to show the arrangement.
Every attached living space has its own problem list: tying new plumbing into old lines, panel capacity, slab and ceiling height on conversions, matching the roofline on additions. We are writing up the specific ones from this job and will add them here.

What the numbers do and do not say.
The casita was part of a whole-home renovation. The published renovation budget covers the entire house, so it is not the cost of the casita.
