The $62,892/Year Question Every Keller Family Is Facing
The average cost of assisted living in the Dallas–Fort Worth area is $5,241 per month — $62,892 every single year. That's money that leaves your family's wealth permanently, year after year, with nothing to show for it.
For Keller homeowners with aging parents or family members who need support but not full medical care, there's a smarter alternative: a granny flat ADU on your own property. You keep your loved one close, you eliminate the facility cost, and you add permanent value to your home.
The Wealth Math: Granny Flat vs. Assisted Living
- Assisted living cost: $5,241/month = $62,892/year = $314,460 over 5 years
- Granny flat build cost in Keller: $125,000 – $185,000
- Savings vs. assisted living over 5 years: $129,460 – $189,460
- Property value increase from ADU: $100,000 – $200,000 in Keller's market
- Net financial advantage of granny flat over 5 years: $229,000 – $389,000
The Real Cost of Waiting
Every month you pay for assisted living instead of building a granny flat costs your family $5,241 — money that builds zero equity and creates zero lasting value. A granny flat pays for itself and then some.
Keller's 1.5-Acre SUP Requirement — and the Guest Quarters Workaround
Keller's zoning code requires a Special Use Permit (SUP) for a full detached ADU on lots smaller than 1.5 acres. For many Keller homeowners on standard residential lots, this can seem like a barrier.
However, there's a well-established workaround: the Guest Quarters permit. A Guest Quarters allows you to build a fully habitable, private living space — bedroom, bathroom, living area, and efficiency kitchen — without triggering the SUP requirement. For multigenerational living purposes, a Guest Quarters unit is functionally identical to a granny flat.
DFW ADU Pro® has navigated this exact scenario dozens of times in Keller. We know which path is right for your lot and your goals.
