The UAE does not have a single federal indoor-air law setting chemical contaminant limits for every occupied building. Instead, the relevant framework is divided between Dubai Municipality technical guidance, Al Sa'fat building requirements, Abu Dhabi occupational Codes of Practice, federal occupational references and national policy.
Dubai Municipality's Technical Guidelines for Indoor Air Quality for Healthy Life, document reference DM-HSD-GU119-IAQ, Version 4, was issued on 11 December 2024 by the Health and Safety Department, Environmental Health Section. Its scope excludes premises exclusively dedicated to industrial and medical sectors. Testing carried out under the guideline must be undertaken by a company or laboratory accredited by the Emirates International Accreditation Centre.
The guideline contains different routes for new and existing buildings. Clause 9-8-3 applies to new buildings and states that buildings which optionally apply the listed procedures will be awarded an indoor air quality certificate by Dubai Municipality. Table 1 therefore contains entry conditions for a voluntary certification route. Its figures must always be described with that status and should not be presented as general statutory limits applying to every new building in Dubai.
Clause 9-8-4 addresses existing buildings. Table 2 is expressed in mandatory terms within Dubai Municipality's technical guideline, contains no "optionally" qualifier and states that testing must be carried out. The technical guideline is not statutory law, however, and Table 2 is not a voluntary certification route. The distinction is important: it is neither accurate to describe Table 2 as optional nor accurate to convert the guideline into a general statement that Dubai law requires indoor-air testing.
Table 1 and Table 2 serve different building categories and have different status. Table 1 sits within the optional certificate route for new buildings, while Table 2 is the existing-building route expressed in mandatory terms within the guideline. Results should therefore identify the table applied, the building status and the relevant averaging period.
The numerical objectives also differ. For example, the Table 1 long-term TVOC value is 300 micrograms per cubic metre over 8 hours, while Table 2 gives 0.6 milligrams per cubic metre over 8 hours, equal to 600 micrograms per cubic metre. The existing-building figure is therefore more lenient, and the two values should never be merged into a single Dubai Municipality TVOC limit.
Formaldehyde demonstrates a different problem. Dubai Municipality gives 0.01 ppm over 8 hours, while the 0.08 ppm value, equal to 0.1 milligrams per cubic metre, is the short-term value over 30 minutes. Published summaries have sometimes transposed these columns. A regulatory map must preserve the correct averaging periods rather than repeat the incorrect claim that Dubai Municipality sets 0.08 ppm over 8 hours.
Al Sa'fat, the Dubai Green Building System, 2nd edition, January 2023, replaced the Dubai Green Building Regulations and Specifications on 19 October 2020. It is a building-code and rating instrument rather than occupational-health law. The Silver Sa'fa is the mandatory minimum within the Al Sa'fat framework for all new buildings; Bronze is not the mandatory level.
Section 401.01, mandatory at Silver, requires compliance with the latest editions of ASHRAE Standards 62.1, 62.2 and 170. No edition year should be attached when citing this Al Sa'fat provision because the instrument itself uses the words "latest edition". Sections 404.01 and 404.02, also mandatory at Silver, address VOC content in paints, coatings, adhesives, primers and sealants by referring to limits specified by Dubai Municipality and certification by Dubai Central Laboratory. Those sections do not state their own grams-per-litre values.
Section 401.07 applies to listed categories of existing buildings and states that the buildings must apply the specified procedures. It includes chemical and other indoor-environment figures and requires retesting within 5 years of the last compliant test. Its status and scope should be reported accurately without turning Al Sa'fat into a general occupational-exposure law or a universal federal standard.
In Abu Dhabi, ADPHC Code of Practice 8.0 General Workplace Amenities, Version 4.0, effective 15 July 2024, operates under the ADOSH-SF framework. ADPHC states that its Codes of Practice are mandatory to all entities regardless of risk classification. That statement concerns the occupational framework and should not be expanded into a claim that the Code regulates every building occupant or creates a general indoor-air testing regime.
Section 3.2(c) states that workspaces shall be free from biological and chemical hazards. Section 3.7 covers HVAC, and section 3.7(d) requires fresh-air intakes to be located so that they do not draw in vehicle exhaust, noxious fumes, unpleasant smells or chemical contaminants. The Code also gives ventilation minima for different workplace types and includes minimum space and ceiling-height provisions.
ADPHC Code of Practice 1.0 Hazardous Materials, Version 4.0, also effective 15 July 2024, addresses chemical agents at work. Section 3.2(a) requires employers, so far as is reasonably practicable, to ensure that people are not exposed to safety and health risks from hazardous materials. This is an occupational duty directed at work activities and hazardous materials, not a general building-occupant indoor-air limit.
ADPHC Code of Practice 8.0 section 3.1.1(b) requires compliance with MOHRE Administrative Decision No. (19) of 2023 Regarding Guidelines for Occupational Health and Safety Procedures, issued in implementation of Federal Law No. 33 of 2021. That is the permitted route for citing the Decision in this context, and no article number should be attached to it.
The reference does not convert every indoor chemical concern into a federal indoor-air testing duty. It remains part of an occupational safety and health framework concerned with workplaces, employers and work-related conditions. Building-owner, developer, tenant and public-occupancy questions may fall under different instruments or may not have a directly applicable chemical limit.
ADPHC's separate OSH Standards and Guideline Values document is currently suspended. Its own page states that entities are to comply with relevant local or federal standards in force. It must therefore not be used as a source of any chemical limit, and figures previously attributed to it should not be carried forward into current assessments.
Dubai Law No. (11) of 2024, issued on 25 April 2024, established DECCA and transferred those Dubai Municipality functions falling within DECCA's remit. Indoor air quality is not mentioned in that law. Dubai Municipality then issued Version 4 of DM-HSD-GU119-IAQ on 11 December 2024, nearly eight months later.
Indoor air quality therefore remains with Dubai Municipality. A report should continue to cite Dubai Municipality for the technical guideline and should not attribute the guideline or its building-testing provisions to DECCA.
The UAE National Air Quality Agenda 2031 identifies outdoor air quality, indoor air quality, ambient odour and ambient noise as four focus areas. It is a policy agenda, not law. It can show national direction and priorities, but it does not itself create a building-specific contaminant limit or a testing obligation.
There is no federal UAE indoor-air limit for chemical contaminants that applies across all building types and all emirates. Dubai has the most developed building-focused instruments among the sources considered here, while Abu Dhabi's verified provisions are principally occupational Codes of Practice and the Estidama rating system, which includes an indoor-environment category.
Estidama may be relevant to the design and rating of Abu Dhabi projects, but it should not be used to invent a universal chemical limit, a statutory testing duty or an unverified credit requirement. Its role is different from Dubai Municipality's technical guideline and from ADPHC's workplace Codes of Practice.
Most emirates have no equivalent verified instrument setting a comprehensive suite of indoor chemical contaminant values for ordinary occupied buildings. In those locations, recognised international guidance, project specifications, contractual requirements and competent risk assessment may assist interpretation, but their status must be stated honestly. International recommendations do not become UAE law merely because they are technically respected.
The absence of a universal limit does not mean that chemical contamination is irrelevant or that no duty can arise under another part of building, public-health, occupational or contractual practice. It means that each case requires a source-specific legal and technical map rather than a broad claim that all UAE buildings are governed by one indoor-air standard.
Indoor air quality in Dubai is addressed principally by Dubai Municipality's Technical Guidelines for Indoor Air Quality for Healthy Life, reference DM-HSD-GU119-IAQ, Version 4, issued on 11 December 2024. The status of its figures is not uniform, and the distinction matters. For new buildings, clause 9-8-3 states that the buildings which optionally apply the procedures will be awarded an indoor air quality certificate, so the Table 1 limits operate as the entry conditions of a voluntary certification route rather than as a general legal duty. For existing buildings, clause 9-8-4 is worded differently: testing for the contaminants in Table 2 must be carried out, without the optional qualifier. Separately, Al Sa'fat, Dubai's green building system, whose Silver Sa'fa requirements are mandatory for new buildings, sets its own indoor air quality testing requirements for listed categories of existing building. Al Sa'fat is a building-code and rating instrument rather than occupational health legislation, and its figures differ from the guideline's in places. Any figure drawn from these documents should be read together with the status of the specific clause it comes from.
Dubai Municipality DM-HSD-GU119-IAQ Version 4 (11 December 2024) — clause 9-8-3 figures apply to a voluntary certificate route; clause 9-8-4 is worded as mandatory within the guideline
No. There is no single federal requirement for chemical testing in every occupied building. Dubai Municipality has a technical guideline with separate new- and existing-building routes, Al Sa'fat applies within its building framework, and Abu Dhabi has occupational Codes of Practice.
No. Clause 9-8-3 states that buildings which optionally apply the procedures may receive a Dubai Municipality indoor air quality certificate. Table 1 is therefore part of a voluntary certification route for new buildings.
No. Table 2 is expressed in mandatory terms within the existing-building provisions of Dubai Municipality's technical guideline and contains no optional-certification wording. The guideline is not statutory law, so that status should not be overstated.
No. Dubai Law No. (11) of 2024 does not mention indoor air quality, and Dubai Municipality issued Version 4 of its indoor-air technical guideline on 11 December 2024. Indoor air quality remained with Dubai Municipality.
No. ADPHC states that the document is currently suspended. Current assessments should rely on relevant local or federal standards in force rather than reproducing figures from the suspended document.
