Avesta Housing is refurbishing a 40-unit affordable apartment complex in Sanford known as Patriot Place.
The $9.6 million renovation is being managed by Scarborough-based Allied Cook Construction.
Located at 24 Patriots Lane, the 40-year-old development has been owned by Portland-based Avesta Housing since 2006.
The complex consists of three garden-style apartment buildings, designed for both individuals and families.
