RentCast long-term rent range with exact-ZIP comparable context. Existing main-house rent is modeled at 2x the regional estimate; proposed-unit estimates remain unadjusted. Low and high monthly scenarios are shown instead of one midpoint. Gross potential only; excludes vacancy, utilities, management, taxes, insurance, repairs, financing, and legal or permit restrictions.

First-floor house addition concept

Option A · First-floor attached addition

The footprint is shaped around available backyard space and connected directly to the existing main house.

Second-floor house addition concept

Option B · Second-floor addition

A second-floor option uses the existing building footprint and can combine with a smaller connected first-floor remainder.
