Low and Very Low Income: Covenant for 30 Years. A covenant or other document satisfactory to the City Attorney shall be recorded before issuance of a Building Permit, which shall ensure that the low- and very low-income density bonus units are at all times rented or sold to, and remain affordable at, the applicable income level for at least 30 years. If the Compton Redevelopment Agency provides financial assistance to the developer of the project, a longer term of affordability may apply.
