Definition of Open Space

"Open Space" — an area reserved exclusively for parks, playgrounds, recreational uses, schools, roads, places of worship, hospitals, health centers, barangay centers and other similar facilities and amenities. (Sec. 1, P.D. 1216)

Open Space Reservation Requirements

P.D. 953 (1976): 30% of total subdivision area, exclusive of roads and alleys, reserved for parks and recreational areas.

P.D. 957 + P.D. 1216 (1977): 30% of gross area for subdivisions ≥ 1 hectare — with density-based breakdowns: 9% (high density/social), 7% (medium/economic), 3.5% (low/open market).

IRR of B.P. 220 (1982): Separate standards for economic and socialized housing projects in urban and rural areas.

Core Legal Principles from Jurisprudence

Developers cannot be compelled to donate road lots or open spaces. Compulsory donation under Sec. 31 PD 957 is invalid — donation requires animus donandi. DPWH v. Llamas (2017), DAALCO (2024)

Open spaces remain private until validly donated or expropriated with just compensation. White Plains (1998)

City ordinances declaring private road lots public without just compensation are null and void — beyond the ambit of police power. EPCIB v. SRA (2021)

HLURB/HSAC has broad jurisdiction over open space disputes — including mortgage annulment, road lot consolidation, and contractual claims. BDO v. Sunnyside (2016)

P.D. 957 has retroactive effect for non-development cases (Eugenio, 1996) but P.D. 1216 does not (Dueñas, 2004).

Water facilities used by residents for 30+ years constitute open space by easement through prescription; sale thereof is void. Liwag v. Happy Glen (2012)

HOAs may regulate passage through a subdivision for safety and security, even if roads have been donated to the LGU. Kwong v. Diamond HOA (2019)

Donation Rules — Quick Reference

Roads, alleys, sidewalks & playgrounds → may be donated to the LGU (LGU must accept)

Parks & playgrounds → may instead be donated to the Homeowners Association (with LGU consent)

Donated open spaces are non-convertible — no portion may be converted to any other use

A valid donation requires: (1) public instrument (notarized), (2) formal acceptance by the donee. Talayan Village (2015)

Section 31 donation only covers roads/alleys/sidewalks/playgrounds — not other open spaces like water facilities. Expressio unius est exclusio alterius. DAALCO (2024)
