See How Many Affordable Senior Units Your Site Holds

How Many Affordable Senior Units Will Fit My Site?
TestFit is real estate feasibility software that generates site plans on your parcel and calculates what they yield. For an affordable senior community, the answer comes down to three things that are hard to judge from a parcel map.
Reduced parking frees land
Senior affordable residents tend to own fewer cars. Reduced parking frees land for buildings, and the unit count follows.
Two elevators per building
Every building gets a two-car elevator bank so residents are not stranded when one is out of service.
Compact units keep costs down
Compact one- and two-bedroom units and 10 ft floors keep cost per unit down. The plan shows how many fit on each floor.
From Your Parcel to a Deal You Can Underwrite
Start from the affordable senior community your team would build, tune it to your standards, and finish with one model for the site, plan, tabulation and pro forma.

Your parcel and its constraints
- Site boundary: pick the parcel from built-in parcel data with current owner info, draw it, enter metes and bounds, or import a KML/KMZ file
- Setbacks and frontage: front, side and rear setbacks set to the parcel edges
- Zoning: FAR, building and impervious coverage, height limits and parking ratios, pulled in for your parcel so you don't have to dig through the zoning code
- Easements: areas the layout keeps buildings out of
- Site conditions: flood zones, wetlands and topography from Site Intelligence
Every layout starts inside your site's real constraints.

Your product, fine-tuned on the site

55+ Affordable Senior Rental Site Planning FAQ
What is affordable senior housing?
Age-restricted rental housing for income-qualified residents 55 and older, with rents held below market. Units are usually compact one- and two-bedroom apartments.
Why does senior affordable housing need less parking?
Lower-income senior households own fewer cars on average, and many jurisdictions allow reduced parking ratios for age-restricted affordable housing. Check your local code.
Why does every building have two elevators?
So residents who cannot use stairs are not stranded when one elevator is out of service.
